9cd356a3aae8-0 | When the CA administrator and the certificate issuer reside in different AWS accounts, the CA administrator must share CA access\. This is accomplished by attaching a resource\-based policy to the CA\. The policy grants issuance permissions to a specific principal, which may be an AWS account owner, an IAM user, an AWS Organizations ID, or an organizational unit ID\.
Sharing can be done in the management console using AWS Resource Access Manager \(RAM\), which is a standard method for sharing AWS resources across accounts\. When you share a CA resource in AWS RAM with a principal in another account, the required resource\-based policy is attached to the CA automatically\. For more information about RAM, see the [AWS RAM User Guide](https://docs.aws.amazon.com/ram/latest/userguide/)\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/granting-ca-access.md |
9cd356a3aae8-1 | Alternatively, the CA administrator can attach a policy to a CA manually\. This is done using the PCA APIs [PutPolicy](https://docs.aws.amazon.com/acm-pca/latest/APIReference/API_PutPolicy.html), [GetPolicy](https://docs.aws.amazon.com/acm-pca/latest/APIReference/API_GetPolicy.html), and [DeletePolicy](https://docs.aws.amazon.com/acm-pca/latest/APIReference/API_DeletePolicy.html), or the corresponding AWS CLI commands [put\-policy](https://docs.aws.amazon.com/cli/latest/reference/acm-pca/put-policy.html), [get\-policy](https://docs.aws.amazon.com/cli/latest/reference/acm-pca/get-policy.html), and [delete\-policy](https://docs.aws.amazon.com/cli/latest/reference/acm-pca/delete-policy.html)\.
**Cross\-Account Case 1: Issuing a managed certificate using the console**
In this case, the CA administrator uses RAM to share CA access with another AWS account, enabling that account to issue managed ACM certificates\. The diagram shows that RAM can share the CA directly with the account, or indirectly through an AWS Organizations ID in which the account is a member\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/granting-ca-access.md |
9cd356a3aae8-2 | ![\[Cross-account issuance with the console\]](http://docs.aws.amazon.com/acm-pca/latest/userguide/images/ca_access_2_accounts_console.png)
After RAM shares a resource through AWS Organizations, the recipient principal must accept the share for it to take effect\. The recipient can configure AWS Organizations to accept offered shares automatically\.
**Note**
The recipient account is responsible for configuring auto\-renewal in ACM\. Typically, on the first occasion a shared CA is used, ACM installs a service\-linked role that enables it to make unattended certificate calls on ACM Private CA\. If this fails \(usually due to a missing permission\), certificates from the CA will not renew automatically, and only the ACM user can resolve the problem, not the CA administrator\. For more information, see [Using a Service Linked Role \(SLR\) with ACM](https://docs.aws.amazon.com/acm/latest/userguide/acm-slr.html)\.
**Cross\-Account Case 2: Issuing managed and unmanaged certificates using the API/CLI**
This second case demonstrates the sharing and issuance options that are possible using the AWS Certificate Manager and ACM Private CA APIs\. All of these operations can also be carried out using the corresponding AWS CLI commands\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/granting-ca-access.md |
9cd356a3aae8-3 | ![\[Cross-account issuance using the APIs\]](http://docs.aws.amazon.com/acm-pca/latest/userguide/images/ca_access_2_accounts_api_options.png)
Because the APIs are being used directly in this example, the certificate issuer has a choice of two APIs to issue a certificate\. The PCA API action `IssueCertificate` results in an unmanaged certificate that will not be automatically renewed and must be exported and manually installed\. The ACM API action [RequestCertificate](https://docs.aws.amazon.com/acm/latest/APIReference/API_RequestCertificate.html) results in a managed certificate that can be easily installed on ACM\-integrated services and renews automatically\.
**Note**
The recipient account is responsible for configuring auto\-renewal in ACM\. Typically, on the first occasion a shared CA is used, ACM installs a service\-linked role that allows I to make unattended certificate calls on ACM Private CA\. If this fails \(usually due to a missing permission\), certificates from the CA will not renew automatically, and only the ACM user can resolve the problem, not the CA administrator\. For more information, see [Using a Service Linked Role \(SLR\) with ACM](https://docs.aws.amazon.com/acm/latest/userguide/acm-slr.html)\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/granting-ca-access.md |
9f50d8b31fe6-0 | With ACM Private CA, you can create a hierarchy of certificate authorities with up to five levels\. The root CA, at the top of a hierarchy tree, can have any number of branches\. The root CA can have as many as four levels of subordinate CAs on each branch\. You can also create multiple hierarchies, each with its own root\.
A well\-designed CA hierarchy offers the following benefits:
+ Granular security controls appropriate to each CA
+ Division of administrative tasks for better load balancing and security
+ Use of CAs with limited, revocable trust for daily operations
+ Validity periods and certificate path limits
The following diagram illustrates a simple, three\-level CA hierarchy\.
![\[Diagram of a simple, three-level CA hierarchy.\]](http://docs.aws.amazon.com/acm-pca/latest/userguide/images/simple-ca-tree.png)
Each CA in the tree is backed by an X\.509 v3 certificate with signing authority \(symbolized by the pen\-and\-paper icon\)\. This means that as CAs, they can sign other certificates subordinate to them\. When a CA signs a lower\-level CA's certificate, it confers limited, revocable authority on the signed certificate\. The root CA in level 1 signs high\-level subordinate CA certificates in level 2\. These CAs, in turn, sign certificates for CAs in level 3 that are used by PKI \(public key infrastructure\) administrators who manage end\-entity certificates\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/ca-hierarchy.md |
9f50d8b31fe6-1 | Security in a CA hierarchy should be configured to be strongest at the top of the tree\. This arrangement protects the root CA certificate and its private key\. The root CA anchors trust for all of the subordinate CAs and the end\-entity certificates below it\. While localized damage can result from the compromise of an end\-entity certificate, compromise of the root destroys trust in the entire PKI\. Root\- and higher\-level subordinate CAs are used only infrequently \(usually to sign other CA certificates\)\. Consequently, they are tightly controlled and audited to ensure a lower risk of compromise\. At the lower levels of the hierarchy, security is less restrictive\. This approach allows the routine administrative tasks of issuing and revoking end\-entity certificates for users, computer hosts, and software services\.
**Note**
Using a root CA to sign a subordinate certificate is a rare event that occurs in only a handful of circumstances:
When the PKI is created
When a high\-level certificate authority needs to be replaced
When a certificate revocation list \(CRL\) or Online Certificate Status Protocol \(OCSP\) responder needs to be configured
Root and other high\-level CAs require highly secure operational processes and access\-control protocols\.

9139fd1a6172-0 | End\-entity certificates derive their trust from a certification path leading back through the subordinate CAs to a root CA\. When a web browser or other client is presented with an end\-entity certificate, it attempts to construct a chain of trust\. For example, it may check to see that the certificate's *issuer distinguished name* and *subject distinguished name* match with the corresponding fields of the issuing CA certificate\. Matching would continue at each successive level up the hierarchy until the client reaches a trusted root that is contained in its trust store\.
The trust store is a library of trusted CAs that the browser or operating system contains\. For a private PKI, your organization's IT must ensure that each browser or system has previously added the private root CA to its trust store\. Otherwise, the certification path cannot be validated, resulting in client errors\.
The next diagram shows the validation path that a browser follows when presented with an end\-entity X\.509 certificate\. Note that the end\-entity certificate lacks signing authority and serves only to authenticate the entity that owns it\.
![\[Validation check by a web browser.\]](http://docs.aws.amazon.com/acm-pca/latest/userguide/images/chain-of-trust.png) | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/ca-hierarchy.md |
9139fd1a6172-1 | The browser inspects the end\-entity certificate\. The browser finds that the certificate offers a signature from subordinate CA \(level 3\) as its trust credential\. The certificates for the subordinate CAs must be included in the same PEM file\. Alternatively, they can also be in a separate file that contains the certificates that make up the trust chain\. Upon finding these, the browser checks the certificate of subordinate CA \(level 3\) and finds that it offers a signature from subordinate CA \(level 2\)\. In turn, subordinate CA \(level 2\) offers a signature from root CA \(level 1\) as its trust credential\. If the browser finds a copy of the private root CA certificate preinstalled in its trust store, it validates the end\-entity certificate as trusted\.
Typically, the browser also checks each certificate against a certificate revocation list \(CRL\)\. An expired, revoked, or misconfigured certificate is rejected and validation fails\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/ca-hierarchy.md |
a2c6f591039b-0 | In general, your CA hierarchy should reflect the structure of your organization\. Aim for a *depth* \(that is, number of CA levels\) no greater than necessary to delegate administrative and security roles\. Adding a CA to the hierarchy means increasing the number of certificates in the certification path, which increases validation time\. Keeping the depth to a minimum also reduces the number of certificates sent from the server to the client when establishing trust\. A smaller depth also decreases the amount of work that a client performs to validate an end\-entity certificate\.
In theory, a root CA, which has no [path\-length parameter](#length-constraints), can authorize any depth of subordinate CAs\. A subordinate CA can have as many child subordinate CAs as are allowed by its internal configuration\. ACM Private CA managed hierarchies support CA certification paths up to five levels deep\.
Well designed CA structures have several benefits:
+ Separate administrative controls for different organizational units
+ The ability to delegate access to subordinate CAs
+ A hierarchical structure that protects higher\-level CAs with additional security controls
Two common CA structures accomplish all of this:
+ **Two CA levels: root CA and subordinate CA**
This is the simplest CA structure that allows separate administration, control, and security policies for the root CA and a subordinate CA\. You can maintain restrictive controls and policies for your root CA while allowing more permissive access for the subordinate CA\. The latter is used for bulk issuance of end\-entity certificates\.
+ **Three CA levels: root CA and two layers of subordinate CA** | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/ca-hierarchy.md |
a2c6f591039b-1 | + **Three CA levels: root CA and two layers of subordinate CA**
Similar to the above, this structure adds an additional CA layer to further separate the root CA from low\-level CA operations\. The middle CA layer is only used to sign subordinate CAs that carry out the issuance of end\-entity certificates\.
Less common CA structures include the following:
+ **Four or more CA levels**
Though less common than three\-level hierarchies, CA hierarchies with four or more levels are possible and may be required to allow administrative delegation\.
+ **One CA level: root CA only**
This structure is commonly used for development and testing when a full chain of trust is not required\. Used in production, it is atypical\. Moreover, it violates the best practice of maintaining separate security policies for the root CA and the CAs that issue end\-entity certificates\.
However, if you are already issuing certificates directly from a root CA, you can migrate to ACM Private CA\. Doing so provides security and control advantages over using a root CA managed with OpenSSL or other software\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/ca-hierarchy.md |
86c70d69ba5f-0 | In this example, a hypothetical technology company manufactures two Internet of Things \(IoT\) products, a smart light bulb and a smart toaster\. During production, each device is issued an end\-entity certificate so it can communicate securely over the internet with the manufacturer\. The company's PKI also secures its computer infrastructure, including the internal website and various self\-hosted computer services that run finance and business operations\.
Consequently, the CA hierarchy closely models these administrative and operational aspects of the business\.
![\[Diagram of a more complex CA hierarchy.\]](http://docs.aws.amazon.com/acm-pca/latest/userguide/images/multilevel-ca-tree.png)
This hierarchy contains three roots, one for Internal Operations and two for External Operations \(one root CA for each product line\)\. It also illustrates multiple certification depths, with two levels of CA for Internal Operations and three levels for External Operations\.
The use of separated root CAs and additional depth on the External Operations side is a design decision serving business and security needs\. With multiple CA trees, the PKI is future\-proofed against corporate reorganizations, divestitures, or acquisitions\. When changes occur, an entire root CA hierarchy can move cleanly with the division it secures\. And with two levels of subordinate CA, the roots CAs have a high level of isolation from the level 3 CAs that are responsible for bulk\-signing the certificates for thousands or millions of manufactured items\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/ca-hierarchy.md |
86c70d69ba5f-1 | On the internal side, corporate web and internal computer operations complete a two\-level hierarchy\. These levels allow web administrators and operations engineers to manage certificate issuance independently for their own work domains\. The compartmentalization of PKI into distinct functional domains is a security best practice and protects each from a compromise that might affect the other\. Web administrators issue end\-entity certificates for use by web browsers throughout the company, authenticating and encrypting communications on the internal website\. Operations engineers issue end\-entity certificates that authenticate data center hosts and computer services to one another\. This system helps keep sensitive data secure by encrypting it on the LAN\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/ca-hierarchy.md |
eed7588a2573-0 | The structure of a CA hierarchy is defined and enforced by the *basics constraints extension* that each certificate contains\. The extension defines two constraints:
+ `cA` – Whether the certificate defines a CA\. If this value is *false* \(the default\), then the certificate is an end\-entity certificate\.
+ `pathLenConstraint` – The maximum *additional* depth of a certification path that includes the certificate\.
A root CA certificate needs maximum flexibility and does not include a path length constraint\. This allows the root to define a certification path of any depth\.
**Note**
ACM Private CA limits the certification path to five levels\.
Subordinate CAs have `pathLenConstraint` values equal to or greater than zero, depending on location in the hierarchy placement and desired features\. For example, in a hierarchy with three CAs, no path constraint is specified for the root CA\. The first subordinate CA has a path length of 1 and can therefore sign child CAs\. Each of these child CAs must necessarily have a `pathLenConstraint` value of zero\. This means that they can sign end\-entity certificates but cannot issue additional CA certificates\. Limiting the power to create new CAs is an important security control\.
The following diagram illustrates this propagation of limited authority down the hierarchy\.
![\[Diagram of a simple, three-level CA hierarchy.\]](http://docs.aws.amazon.com/acm-pca/latest/userguide/images/path-length.png) | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/ca-hierarchy.md |
eed7588a2573-1 | In this four\-level hierarchy, the root is unconstrained \(as always\)\. But the first subordinate CA has a `pathLenConstraint` value of 2, which limits its child CAs from going more than two levels deeper\. Consequently, for a valid certification path, the constraint value must decrement to zero in the next two levels\. If a web browser encounters an end\-entity certificate from this branch that has a path length greater than four, validation fails\. Such a certificate could be the result of an accidentally created CA, a misconfigured CA, or a unauthorized issuance\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/ca-hierarchy.md |
a919a4f626cc-0 | ACM Private CA provides templates for issuing root, subordinate, and end\-entity certificates\. These templates encapsulate best practices for the basic constraints values, including path length\. The templates include the following:
+ RootCACertificate/V1
+ SubordinateCACertificate\_PathLen0/V1
+ SubordinateCACertificate\_PathLen1/V1
+ SubordinateCACertificate\_PathLen2/V1
+ SubordinateCACertificate\_PathLen3/V1
+ EndEntityCertificate/V1
The `IssueCertificate` API will return an error if you attempt to create a CA with a path length greater than or equal to the path length of its issuing CA certificate\.
For more information about certificate templates, see [Understanding Certificate Templates](UsingTemplates.md)\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/ca-hierarchy.md |
8e5cd402ebde-0 | Once you have settled on a design for your CA hierarchy, you can test it and put it into production using a AWS CloudFormation template\. For an example of such a template, see [Declaring a Private CA Hierarchy](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-acmpca-certificateauthority.html#aws-resource-acmpca-certificateauthority--examples) in the *AWS CloudFormation User Guide*\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/ca-hierarchy.md |
a556c63ba2db-0 | The following Java sample shows how to use the [PutPolicy](https://docs.aws.amazon.com/acm-pca/latest/APIReference/API_PutPolicy.html) operation\.
The operation attaches a resource\-based policy to a private CA, enabling cross\-account sharing\. When authorized by a policy, a principal residing in another AWS account can issue and renew private end\-entity certificates using a private CA that it does not own\. You can find the ARN of a private CA by calling the [ListCertificateAuthorities](https://docs.aws.amazon.com/acm-pca/latest/APIReference/API_ListCertificateAuthorities.html) action\. For examples of policies, see the ACM Private CA guidance on [Resource\-Based Policies](https://docs.aws.amazon.com/acm-pca/latest/userguide/pca-rbp.html)\.
Once a policy is attached to a CA, you can inspect it with the [GetPolicy](https://docs.aws.amazon.com/acm-pca/latest/APIReference/API_GetPolicy.html) action or delete it with the [DeletePolicy](https://docs.aws.amazon.com/acm-pca/latest/APIReference/API_DeletePolicy.html) action\.

adacf2be4b00-0 | After you [create](PcaCreateCa.md) your private CA, [retrieve](PcaGetCsr.md) the certificate signing request \(CSR\), and [sign](PcaSignCert.md) the CA certificate, you must import the certificate into ACM Private CA\. After signing and importing the certificate, you can use your private CA to issue and revoke trusted private SSL/TLS certificates\. These enable trusted communication between users, applications, computers, and other devices internal to your organization\. The certificates cannot be publicly trusted\.
You must also retrieve the certificate chain that contains the certificate of the intermediate or root CA used to sign your private CA certificate and any preceding certificates\. To create the chain, concatenate your root certificate, if available, and any subordinate certificates that you might have into a single file\. You can use the `cat` command \(Linux\) to do so\. Each certificate must directly certify the one preceding\. The following example contains three certificates, but your PKI infrastructure might have more or fewer\.
**Note**
Your chain must be PEM formatted\.
```
-----BEGIN CERTIFICATE-----
Base64-encoded intermediate CA certificate
-----END CERTIFICATE-----

abbabcf8024e-0 | Access to ACM Private CA requires credentials that AWS can use to authenticate your requests\. The following topics provide details on how you can use [AWS Identity and Access Management \(IAM\)](https://docs.aws.amazon.com/IAM/latest/UserGuide/introduction.html) to help secure your private certificate authorities \(CAs\) by controlling who can access them\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/security-iam.md |
f81e9fc331a0-0 | You can access AWS as any of the following types of identities:
+ **AWS account root user** – When you first create an AWS account, you begin with a single sign\-in identity that has complete access to all AWS services and resources in the account\. This identity is called the AWS account *root user* and is accessed by signing in with the email address and password that you used to create the account\. We strongly recommend that you do not use the root user for your everyday tasks, even the administrative ones\. Instead, adhere to the [best practice of using the root user only to create your first IAM user](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#create-iam-users)\. Then securely lock away the root user credentials and use them to perform only a few account and service management tasks\.
+ **IAM user** – An [IAM user](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_users.html) is an identity within your AWS account that has specific custom permissions \(for example, permissions to create a directory in ACM Private CA\)\. You can use an IAM user name and password to sign in to secure AWS webpages like the [AWS Management Console](https://console.aws.amazon.com/), [AWS Discussion Forums](https://forums.aws.amazon.com/), or the [AWS Support Center](https://console.aws.amazon.com/support/home#/)\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/security-iam.md |
f81e9fc331a0-1 | In addition to a user name and password, you can also generate [access keys](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_access-keys.html) for each user\. You can use these keys when you access AWS services programmatically, either through [one of the several SDKs](https://aws.amazon.com/tools/#sdk) or by using the [AWS Command Line Interface \(CLI\)](https://aws.amazon.com/cli/)\. The SDK and CLI tools use the access keys to cryptographically sign your request\. If you don’t use AWS tools, you must sign the request yourself\. ACM Private CA supports *Signature Version 4*, a protocol for authenticating inbound API requests\. For more information about authenticating requests, see [Signature Version 4 Signing Process](https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html) in the *AWS General Reference*\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/security-iam.md |
f81e9fc331a0-2 | + **IAM role** – An [IAM role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles.html) is an IAM identity that you can create in your account that has specific permissions\. An IAM role is similar to an IAM user in that it is an AWS identity with permissions policies that determine what the identity can and cannot do in AWS\. However, instead of being uniquely associated with one person, a role is intended to be assumable by anyone who needs it\. Also, a role does not have standard long\-term credentials such as a password or access keys associated with it\. Instead, when you assume a role, it provides you with temporary security credentials for your role session\. IAM roles with temporary credentials are useful in the following situations:
+ **Federated user access** – Instead of creating an IAM user, you can use existing identities from AWS Directory Service, your enterprise user directory, or a web identity provider\. These are known as *federated users*\. AWS assigns a role to a federated user when access is requested through an [identity provider](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_providers.html)\. For more information about federated users, see [Federated Users and Roles](https://docs.aws.amazon.com/IAM/latest/UserGuide/introduction_access-management.html#intro-access-roles) in the *IAM User Guide*\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/security-iam.md |
f81e9fc331a0-3 | + **AWS service access** – A service role is an IAM role that a service assumes to perform actions in your account on your behalf\. When you set up some AWS service environments, you must define a role for the service to assume\. This service role must include all the permissions that are required for the service to access the AWS resources that it needs\. Service roles vary from service to service, but many allow you to choose your permissions as long as you meet the documented requirements for that service\. Service roles provide access only within your account and cannot be used to grant access to services in other accounts\. You can create, modify, and delete a service role from within IAM\. For example, you can create a role that allows Amazon Redshift to access an Amazon S3 bucket on your behalf and then load data from that bucket into an Amazon Redshift cluster\. For more information, see [Creating a Role to Delegate Permissions to an AWS Service](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_create_for-service.html) in the *IAM User Guide*\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/security-iam.md |
f81e9fc331a0-4 | + **Applications running on Amazon EC2** – You can use an IAM role to manage temporary credentials for applications that are running on an EC2 instance and making AWS CLI or AWS API requests\. This is preferable to storing access keys within the EC2 instance\. To assign an AWS role to an EC2 instance and make it available to all of its applications, you create an instance profile that is attached to the instance\. An instance profile contains the role and enables programs that are running on the EC2 instance to get temporary credentials\. For more information, see [Using an IAM Role to Grant Permissions to Applications Running on Amazon EC2 Instances](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-ec2.html) in the *IAM User Guide*\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/security-iam.md |
c9cd27848a86-0 | In ACM Private CA, the primary resource that you work with is a *certificate authority \(CA\)*\. Every private CA that you own or control is identified by an Amazon Resource Name \(ARN\), which has the following form\.
```
arn:aws:acm-pca:AWS_Region:AWS_Account:certificate-authority/12345678-abcd-1234-abcd-1234567890ab
```
A *resource owner* is the *principal entity* of the AWS account in which an AWS resource is created\. The following examples illustrate how this works\.
+ If you use the credentials of your AWS account root user to create a private CA, your AWS account owns the CA\.
+ If you create an IAM user in your AWS account, you can grant that user permission to create a private CA\. However, the account to which that user belongs owns the CA\.
+ If you create an IAM role in your AWS account and grant it permission to create a private CA, anyone who can assume the role can create the CA\. However, the account to which the role belongs will own the private CA\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/security-iam.md |
964db33cc739-0 | A *permissions policy* describes who has access to what\. The following discussion explains the available options for creating permissions policies\.
**Note**
This documentation discusses using IAM in the context of ACM Private CA\. It doesn't provide detailed information about the IAM service\. For complete IAM documentation, see the [IAM User Guide](https://docs.aws.amazon.com/IAM/latest/UserGuide/introduction.html)\. For information about IAM policy syntax and descriptions, see [AWS IAM Policy Reference](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies.html)\.
When you set up access control and permissions policies that you plan to attach to an IAM identity \(identity\-based policies\), use the following table as a reference\. The first column in the table lists each ACM Private CA API operation\. You specify actions in a policy's `Action` element\. The remaining columns provide the additional information\.

You can use IAM to create policies that apply permissions to IAM users, groups, and roles\. These are called *identity\-based policies*\. IAM offers the following types of identity\-based policies:
+ [AWS Managed Policies](#auth-AwsManagedPolicies) are policies available by default with ACM Private CA\. These policies cover basic user roles\.
+ [Customer Managed Policies](#auth-CustManagedPolicies) are policies that you create and manage in your AWS account and which you can attach to multiple users, groups, and roles\. You have more precise control when using customer managed policies than you have when using AWS managed policies\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/security-iam.md |
964db33cc739-8 | + [Inline Policies](#auth-InlinePolicies) are policies that you create and manage and which you embed directly into a single user, group, or role\.
+ [Resource\-Based Policies](pca-rbp.md) are used by ACM Private CA to enable cross\-account access to private CAs\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/security-iam.md |
abaffb335206-0 | ACM Private CA includes a set of predefined AWS managed policies for administrators, users, and auditors\. Understanding these policies can help you implement [Customer Managed Policies](#auth-CustManagedPolicies)\.
+ **FullAccess** – Unrestricted administrative control\.

cf9049ea075a-0 | As a best practice, don't use your AWS account root user to interact with AWS, including ACM Private CA\. Instead use AWS Identity and Access Management \(IAM\) to create an IAM user, IAM role, or federated user\. Create an administrator group and add yourself to it\. Then log in as an administrator\. Add additional users to the group as needed\.
Another best practice is to create a customer managed IAM policy that you can assign to users\. Customer managed policies are standalone identity\-based policies that you create and which you can attach to multiple users, groups, or roles in your AWS account\. Such a policy restricts users to performing only the ACM Private CA actions that you specify\.
The following example [customer\-managed policy](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_managed-using.html#create-managed-policy-console) allows a user to create a CA audit report\. This is an example only\. You can choose any ACM Private CA operations that you want\. For more examples, see [Inline Policies](#auth-InlinePolicies)\.
**To create a customer managed policy**
1. Sign in to the IAM console using the credentials of an AWS administrator\.
1. In the navigation pane of the console, choose **Policies**\.
1. Choose **Create policy**\.
1. Choose the **JSON** tab\.
1. Copy the following policy and paste it into the editor\.

1c11ba2a57a3-0 | After you [create](PcaCreateCa.md) your private CA using ACM Private CA and [retrieve](PcaGetCsr.md) a certificate signing request \(CSR\), you must take the CSR to your external X\.509 infrastructure\. Use an intermediate or root CA to create your private CA certificate and sign it\. Signing affirms the identity of the private CA within your organization\. When you have completed this process, follow the instructions in [Import Your Private CA Certificate into ACM Private CA](PcaImportCaCert.md)\.
**Important**
Details of your X\.509 infrastructure and the CA hierarchy within it are beyond the scope of this guide\. For more information, see [Creating and Signing a Private CA Certificate](PcaTsSignCsr.md)\.
The validity period of a private CA is determined by the validity period you specify when you create the private CA certificate\. Set the **Not Before** and **Not After** fields\. Aside from enforcing the defined period, ACM Private CA does not restrict the lifetime of a CA\.
If you must create a CA certificate that does not effectively expire, set the special value `99991231235959Z` in the **Not After** field\. We do not recommend this as a general practice\.
The signed certificate is typically returned to you as a base64\-encoded PEM file or string\. This is shown by the following example\. If the certificate is encoded in a different format, you must convert it to PEM\. Various OpenSSL commands are available to perform format conversion\.
``` | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/PcaSignCert.md |
1c11ba2a57a3-1 | ```
-----BEGIN CERTIFICATE-----
MIIDRzCCA..................
..........9YFbLXtPgZooy2IgZ
------END CERTIFICATE------
```
You can use the OpenSSL `x509` command to view the contents of your signed PEM format certificate\.
```
openssl x509 -in path_to_certificate_file -text -noout
```
This command outputs a certificate similar to the following example\.

Alternatively, an ACM Private CA administrator can use the PCA APIs [PutPolicy](https://docs.aws.amazon.com/acm-pca/latest/APIReference/API_PutPolicy.html), [GetPolicy](https://docs.aws.amazon.com/acm-pca/latest/APIReference/API_GetPolicy.html), and [DeletePolicy](https://docs.aws.amazon.com/acm-pca/latest/APIReference/API_DeletePolicy.html), or the corresponding AWS CLI commands [put\-policy](https://docs.aws.amazon.com/cli/latest/reference/acm-pca/put-policy.html), [get\-policy](https://docs.aws.amazon.com/cli/latest/reference/acm-pca/get-policy.html), and [delete\-policy](https://docs.aws.amazon.com/cli/latest/reference/acm-pca/delete-policy.html), to apply and manage resource\-based policies\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/pca-rbp.md |
46d398ab81ec-1 | For general information about resource\-based policies, see [Identity\-Based Policies and Resource\-Based Policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_identity-vs-resource.html) and [Controlling Access Using Policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_controlling.html)\.
An AWS Certificate Manager \(ACM\) user who has received shared access to a private CA can issue managed end\-entity certificates that are signed by the CA\. Users with cross\-account shared access to a CA may only issue certificates that use the `EndEntityCertificate/V1` template\.
The following examples contain resource\-based policies and the commands to apply them\. In addition to specifying the ARN of a CA, the administrator provides an AWS user account ID or an AWS Organizations ID that will be granted access to the CA\. For readability, the JSON of each policy is provided as a file instead of inline\.
**Note**
The structure of the JSON resource\-based polices shown below must be followed precisely\. Only the ID fields for the principals \(the AWS account number or the AWS Organizations ID\) and the CA ARNs can be configured by customers\.

3546700121b1-0 | You can restore a private CA that has been deleted as long as the CA remains within the restoration period that you specified upon deletion\. The period identifies the number of days, from 7 to 30, that the private CA remains restorable\. At the end of that period, the private CA is permanently deleted\. For more information, see [Deleting Your Private CA](PCADeleteCA.md)\. You cannot restore a private CA that has been permanently deleted\.
**Note**
You are not charged for a private CA after it has been deleted\. However, if a deleted CA is restored, you are charged for the time between deletion and restoration\. For more information, see [Pricing](PcaPricing.md)\.

3a1f543766b2-0 | You can use the AWS Management Console to restore a private CA\.
**To restore a private CA \(console\)**
1. Sign in to your AWS account and open the ACM Private CA console at [https://console\.aws\.amazon\.com/acm\-pca/home](https://console.aws.amazon.com/acm-pca/home)\.
1. Choose **Private CAs**\.
1. Choose your private CA from the list\.
1. You can restore a private CA if its current status is `DELETED`\. On the **Actions** menu, choose **Restore**\.
1. In the dialog box, choose **Restore** again\.
1. If successful, the status of the private CA is set to its pre\-deletion state\. Choose **Enable** on the **Actions** menu to change its status to `ACTIVE`\. If the private CA was in the `PENDING_CERTIFICATE` state at the time of deletion, you must import a CA certificate into the private CA before you can activate it\. | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/PCARestoreCA.md |
b183c632ad09-0 | Use the [restore\-certificate\-authority](https://docs.aws.amazon.com/cli/latest/reference/acm-pca/restore-certificate-authority.html) command to restore a deleted private CA that is in the `DELETED` state\. The following steps discuss the entire process required to delete, restore, and then reactivate a private CA\.
**To delete, restore, and reactivate a private CA \(AWS CLI\)**
1. Delete the private CA\.
Run the [delete\-certificate\-authority](https://docs.aws.amazon.com/cli/latest/reference/acm-pca/delete-certificate-authority.html) command to delete the private CA\. If the private CA's status is `DISABLED` or `PENDING_CERTIFICATE`, you can set the `--permanent-deletion-time-in-days` parameter to specify the private CA's restoration period from 7 days to 30\. If you do not specify a restoration period, the default is 30 days\. If successful, this command sets the status of the private CA to `DELETED`\.
**Note**
To be restorable, the private CA's status at the time of deletion must be `DISABLED` or `PENDING_CERTIFICATE`\.
```
aws acm-pca delete-certificate-authority \
--certificate-authority-arn arn:aws:acm-pca:region:account:\ | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/PCARestoreCA.md |

certificate-authority/12345678-1234-1234-1234-123456789012 \
--permanent-deletion-time-in-days 16
```
1. Restore the private CA\.
Run the [restore\-certificate\-authority](https://docs.aws.amazon.com/cli/latest/reference/acm-pca/restore-certificate-authority.html) command to restore the private CA\. You must run the command before the restoration period that you set with the delete\-certificate\-authority command expires\. If successful, the command sets the status of the private CA to its pre\-deletion status\.
```
aws acm-pca restore-certificate-authority \
--certificate-authority-arn arn:aws:acm-pca:region:account:\
certificate-authority/12345678-1234-1234-1234-123456789012
```
1. Make the private CA `ACTIVE`\.
Run the [update\-certificate\-authority](https://docs.aws.amazon.com/cli/latest/reference/acm-pca/update-certificate-authority.html) command to change the status of the private CA to `ACTIVE`\.
```
aws acm-pca update-certificate-authority \ | https://github.com/siagholami/aws-documentation/tree/main/documents/aws-private-ca-user-guide/doc_source/PCARestoreCA.md |

7b6a36c588fb-0 | If your private CA hierarchy's root of trust must be a CA outside of ACM Private CA, you can create and self\-sign your own root CA\. Alternatively, you can obtain a private CA certificate that is signed by an external private CA operated by your organization\. Use this externally obtained CA to sign a private subordinate CA certificate that ACM Private CA manages\.
**Note**
Procedures for creating or obtaining an external CA are outside the scope of this guide\.
Using an external parent CA with ACM Private CA also allows you to enforce CA name constraints\. Name constraints are defined in the internet public key infrastructure \(PKI\) standard RFC 5280\. The constraints provide a way for CA administrators to restrict subject names in certificates\. For more information, see the [Name Constraints](https://tools.ietf.org/html/rfc5280#section-4.2.1.10) section of RFC 5280\.
ACM Private CA cannot directly issue CA certificates with name constraints\. However, you can issue CA certificates that include name constraints from an external parent CA\. ACM Private CA will enforce these constraints when issuing subordinate CA and end\-entity certificates\. For more information, see [Enforcing Name Constraints on a Private CA](name_constraints.md)\.
