## Background
RELATED APPLICATION/S
This application claims the benefit of priority under 35 USC §119(e) of U.S. Provisional Patent Application No. 62/243,334 filed Oct. 19, 2015, the contents of which are incorporated herein by reference in their entirety.


FIELD OF THE INVENTION
The present invention relates to the field of Internet connection security.
BACKGROUND
Internet resources made available between web servers and client terminals using domain names, domains, subdomains, or the like, are defined by the Internet address the resources are located at. Domains are described, for example, in Mockapetris, P., “Domain names—concepts and facilities”, IETF STD 13, RFC 1034 [online], November 1987 [retrieved on 2015 Sep. 30], retrieved from the Internet: tools.ietf.org/html/rfc1034, DOI: 10.17487/RFC1034, incorporated herein by reference in its entirety. In further example, domains are described in Mockapetris, P., “Domain names—implementation and specification”, IETF STD 13, RFC 1035 [online], November 1987, [retrieved on 2015 Sep. 30], retrieved from the Internet: http://tools.ietf.org/html/rfc1035, DOI: 10.17487/RFC1035, incorporated herein by reference in its entirety. The Internet resource and client data transferred between the client terminal and the web server may be transferred in an unencrypted connection, such as using a hypertext transfer protocol (HTTP), or on a secure and encrypted connection, such as using HTTP (HTTPS).
Web servers usually provide secure connections to client terminal web browsers and/or applications using transport layer security (TSL) protocols, secure socket layer (SSL) protocols, and/or the like. The TSL protocol is described, for example, in Dierks et al., “The Transport Layer Security (TLS) Protocol Version 1.2”, IETF RFC 5246, [online], August 2008 [retrieved on 2015 Sep. 30], retrieved from the Internet: tools.ietf.org/html/rfc6101, DOI: 10.17487/RFC5246, incorporated herein by reference in its entirety. Such secure connections may use a secure Internet address port 443, a digital certificate, and/or the like. When the client terminal application requires a secure connection, a clienthello security message is sent encapsulated inside a data packet of the computer network infrastructure. The web server may receive secure connection requests to multiple virtual and/or real web sites managed by the server. The clienthello message may include a Server Name Indication (SNI) field to allow the web server to determine the hostname and respective digital certificate to send to the client terminal thereby enabling the secure connection. The SNI protocol extension is described, for example, in Blake-Wilson et al., “Transport Layer Security (TLS) Extensions”, IETF RFC 3546 [online], June 2003 [retrieved on 2015 Sep. 30], retrieved from the Internet: tools.ietf.org/html/rfc3546, DOI 10.17487/RFC3546, incorporated herein by reference in its entirety.
A digital certificate (DC) may be issued by a certification authority (CA), such as Comodo, Symantec, GoDaddy, GlobalSign, DigiCert, and the like. Certificate and certification standards are described, for example, in Cooper et al., “Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile”, IETF RFC 5280 [online], May 2008, [retrieved on 2015 Sep. 30], retrieved from the Internet: tools.ietf.org/html/rfc5280, DOI: 10.17487/RFC5280, incorporated herein by reference in its entirety. The digital certificate includes a public key, the identity of the owner, and the like. The client terminal can then validate the identity of the CA and thereby the validity of the public key before facilitating the secure connection with the web server. Thus the privacy and integrity of the data exchanged between the client terminal and the web server is ensured.
Data encapsulation layers of an Internet protocol include a link layer for physical transport of data packets, an Internet layer for directing the packets to the web servers, a transport layer that may include security protocols, and an application layer that transfers the data between the cline terminal and the web server applications, such as a hypertext transfer protocol (HTTP) and the like. HTTP standards are described, for example, in Fielding et al., “Hypertext Transfer Protocol—HTTP/1.1”, IETF RFC 2616 [online], June 1999, [retrieved on 2015 Sep. 30], retrieved from the Internet: tools.ietf.org/html/rfc2616, DOI: 10.17487/RFC2616, incorporated herein by reference in its entirety. When an application or user of a client terminal requires a secure connection, a special request is made to provide security of the transport layer to application layer, such as using a HTTP Secure (HTTPS) protocol. An application running on the client terminal may require a secure connection to a web server and an HTTPS protocol command is sent to the web server, such as HTTPS://secureconnection.webserver.com/secure_commenction.html and the like. Such as protocol command initiates a clienthello message encapsulated in the data packet to facilitate a secure connection to the web server before transferring date between the client terminal and the web server. The clienthello message may contain the SNI field to allow the web server to return the correct DC for the hostname secureconnection.webserver.com.
The foregoing examples of the related art and limitations related therewith are intended to be illustrative and not exclusive. Other limitations of the related art will become apparent to those of skill in the art upon a reading of the specification and a study of the figures.

DETAILED DESCRIPTION
According to embodiments of the present invention, there are provided methods, devices, and systems to facilitate secure connections between client terminals and unsecure web domains. Methods may comprise actions of automatically intercepting data packets sent to a web server to identify client terminal requests for secure data connections, such as hypertext transfer protocol secure (HTTPS) connection requests, to unsecure Internet resources, such as web domains. The data packets are analyzed to identify the Internet resource requested and the client terminal(s) that are requesting the connection. When the Internet resource and client terminal(s) meet a rule that defines allowable access and/or allowable client terminal(s), a public key certificate, such as a digital certificate, is acquired for the secure connection to be initiated the next time a client terminal requests access to the Internet resource.
Using one or more hardware processors, the web server hosting the unsecure domain may automatically determine that the request for a secure connection was initiated by a legitimate end user of the client terminal. Unsecure domains are, for example, domains that do not have associated digital certificates. The secure connection request is, for example a clienthello message as defined by the transport layer security (TLS) protocol, is automatically identified in a data packet, and a server name identification is automatically located, for example in the clienthello message using the Server Name Identification (SNI) field. By automatically analyzing the data packet information, the Internet protocol address (IP) of the client terminal may be determined. When a rule regarding the acquisition of a digital certificate (DC) for the unsecure domain is satisfied, the hardware processor automatically acquires the DC, and automatically associates the DC with the unsecure domain for sent in response to new client terminal requests for a secure connection. This allows automatically converting the unsecure domain into a secure domain when a legitimate client attempts to access the domain.
Embodiments of the present invention may allow preventing secure connection requests from web crawlers, such as web bots, automated processes, and the like, that are not the intended legitimate clients of the Internet resource and/or domain. Embodiments of the present invention may allow automatically identifying unsecure domains that client terminals are trying to access using a secure connection, and convert the unsecure domains to secure domains being thereby allowing secure connection access to web domains that were not previously accessible.
Optionally, a blacklist of words is maintained to prevent the web server from facilitating a secure connection to the web domain and/or Internet resource from clients that are not legitimate end users or approved by the owner of the resource. For example, if a secure connection is requested from a client terminal that has the word Google, Crawler, and the like associated with the IP address of the client terminal, the secure connection request is determined to be associated with a web crawler and not a legitimate end user.
Optionally, secure connection requests are concentrated on one or more subdomains of a web domain, and a DC is retrieved for each relevant one or more subdomain.
Optionally, a web server restart is initiated after a predefined number of new DCs has been associated with Internet resources on the web server, thereby updating the corresponding DNS entries. Optionally, when two or more hardware processors and/or subsystems exist for a web server system, the two or more hardware processors and/or subsystems are restarted on a rolling basis to prevent a loss of service condition.
Reference is now made to FIG. 1, which is a schematic illustration of a system 200 for automatically securing unsecure domains 203, according to embodiments of the invention. A web server system 200 may comprise one or more hardware processors 205, such as in a web server farm, a series of rack servers, two or more cores in a single hardware processor, two or more processors in a single blade server, and the like, which are examples of multiple processors for managing web resources. FIG. 1 and other drawings describe a simple example embodiment, where the web resource hosting environment is also a computerized system carrying out the embodiment, but in other embodiments, actions may be distributed differently between one or more hardware processors in a virtualized web resource environment, a system of systems, and the like. System 200 comprises a network interface 206 for communicating with a certificate authority 210 and one or more client terminals 221. For example, certificate authority 210 receives an application programming interface (API) communication from hardware processor 205 requesting a digital certificate 207E for a domain 203 through network interface 206. The hardware processor(s) 205 may receive HTTP(S) 220 protocol data packets from client terminal(s) 221 through network interface 206. Network interface 206 may comprise a specific port 206A, such as port 80, for non-secure protocol data packets 220A, and a specific port 206B, such as port 443, for secure data packets 220B.
Web server system 200 may comprise a local or networked repository 207, such as a non-transient computer-readable storage medium, a hard disk, a network attached storage, and the like, for storing a program code. Specifically, a program store may store program code for an automatic data packet interceptor and analyzer 207A that comprises program code to instruct hardware processor(s) 205 to intercept HTTP(S) data packets 220 and determine the domain name of a domain 203 and/or subdomain name of a subdomain 204 stored on repository 207. Data packet interceptor and analyzer 207A may also determine one or more parameters 221P of client terminal(s) 221, such as IP address, physical location, ownership, user name, client terminal type, and/or the like, and store client terminal parameters 221P in a client terminal database (DB) 207D. For example, a client terminal type may be a virtual terminal operated by a web crawler, and the owner name may be GoogleTM, such as a web crawler and the like. A rule manager 207C may comprise program code to instruct hardware processor(s) 205 to retrieve a digital certificate 207E from analysis of domain names and client terminal parameters 221P. An automatic certificate manager 207B may comprise program code to instruct hardware processor(s) 205 to retrieve a digital certification (DC) 207E from certificate authority 210, and may store DC 207E on repository 207. The program code for performing the actions described herein may be arranged in modules as described or in other modules according to requirements.
Reference is now made to FIG. 2A, which is a flowchart of an automatic method 100 for securing unsecure domains, according to embodiments of the invention. Method 100 comprises an automatic action of intercepting 101 data packets, such as by copying data packets from hardware port 443 as at 206B of FIG. 1, for example by inserting an operating system service to instruct hardware processor(s) 205 to intercept data packets. Method 100 comprises an automatic action of analyzing 102 the data packets to determine a name of a domain 203 and/or subdomain 204, client terminal parameters 221P, and the like. Optionally, client terminal parameters 221P are stored in a client terminal database 207D. When client terminal parameters 221P comply with a rule 103 for domain 203 and/or subdomain 204, a digital certificate 207E is automatically retrieved 104 and automatically associated 105 with corresponding domain 203 and/or subdomain 204 on web server system 205. Program code stored in a rule manager 207C may instruct hardware processor(s) 205 to determine when a rule and/or condition is met 103, such as when a client terminal from a target neighborhood has accessed the web domain. When a new client terminal requests a secure connection for domain 203 and/or subdomain 204, a corresponding digital certificate 207E is sent 106 during the TLS protocol negotiation between the new client terminal and web server 200.
Reference is now made to FIG. 2B, which is a flowchart of an automatic method 110 for determining unsecure domain names, according to embodiments of the invention. When a data packet is received 111 via network interface 206 of FIG. 1, hardware processor(s) 205 identifies when the data packet contains a request for a secure connection, such as a clienthello message 112. Program code stored in a data packet interceptor and analyzer 207A may instruct hardware processor(s) 205 to determine when 112 a data packet 220 contains a clienthello message. When the data packet contains the clienthello message, hardware processor(s) 205 determine if the message also contains a domain and/or subdomain identifier, such as a server name identifier 113. When both conditions 112 and 113 exist, a domain name is extracted 114 from the data packet. Optionally, client terminal parameters 221P are determined 115 from a data packet, such as a client terminal Internet protocol address, MAC address, geographical location, user name, and the like. Optionally, secondary parameters are determined 115 by searching for data packet parameters, such as using a search engine, an information service, a database, and the like. The domain name and client terminal parameters 221P may be stored 116 in a client DB for further use.
Reference is now made to FIG. 2C, which is a flowchart of an automatic method 120 for obtaining digital certificates for unsecure domains, according to embodiments of the invention. When data in received data packets has complied with a rule, a digital certificate information is determined 121, such as domain name, domain owner, and the like. The DC information is submitted automatically 122 on a certificate signing request, such as using an API interface to certificate authority (CA) 210. Web server system 200 receives 123 from CA 210 a DC identification (ID) code. A virtual hosting setup, such as a virtual web host, may be created 125 for domain 203 and/or subdomain 204, and the DC ID code is placed 124 on the domain, such as in a hypertext markup language document, a web document, a text document, and/or the like. Hardware processor(s) 205 may send a request to modify 126 the domain name server entry for the domain if needed. When the domain is verified by CA 127, the DC is retrieved 129 from CA 210, and associated 130 with the domain name on web server system 200.
Reference is now made to FIG. 2D, which is a flowchart of an automatic method 140 for converting temporary digital certificates to permanent digital certificates, according to embodiments of the invention. Optionally, a temporary DC is retrieved 141 and associated with the domain name prior to retrieving 144 a permanent DC. For example, a web server 200 monitors 142 a secure connection until a permanent DC rule is satisifed 143 and then the permanent DC is retrieved. When a number of unique client terminals exceeds a predefined threshold determined by a permanent DC rule, a permanent DC may be retrieved 144.
In some embodiments of the invention, public key encryption is used to establish secure data connections between a client terminal and an Internet Resource hosted on a web server. The resource owner is contacted to approve the secure connection for the client terminal, and the owner allows a temporary or permanent public key certificate for encryption of the secure data connection. The certificate includes information on the key, the owner and a digital signature verifying the contents of the certificate. The certificate allows the owner to control the access of client terminals to the Internet resource, for example by digital certificates provided by a certificate authority and described herein as TLS and/or SSL security.
When a web server receives a secure connection request to an unsecure Internet resource, such as a web domain without a DC, the connection is rejected and the request is ignored by the server. The unsuccessful secure connection requests may not be logged by the server. Since there is log on the server of unsuccessful requests, the web server is not capable of automatically detecting these requests and taking corrective action to secure the unsecure Internet resource. Embodiments of the present invention allow detecting these requests associating a temporary or permanent DC with the Internet resource.
Since many new web sites may be experimental, temporary, transitional, and the like, the cost of acquiring a digital certificate (DC) from a large numbers of new sites may be very high. Furthermore, many web crawlers, bots, Internet search providers, and the like, are not the intended clients for the web sites but may continuously and frequently access web sites to acquire information on the web sites for their own purposes. An owner of a web site, a web hosting service, and the like may want to optimize the expenses acquiring DCs for multiple sites by postponing the acquisition as much as possible, avoid acquiring DCs for obsolete or unused web sites, and the like.
In some secure connection request circumstances, a web server may have a very large list of DCs for an Internet resource, and send a truncated list of DCs to the client terminal to avoid overloading the network connection bandwidth. In these cases, some embodiments of the invention may determine the correct DC to send the client based on information in the client terminal database.
In the description and claims of the application, each of the words “comprise” “include” and “have”, and forms thereof, are not necessarily limited to members in a list with which the words may be associated. In addition, where there are inconsistencies between this application and any document incorporated by reference, it is hereby intended that the present application controls.

identifying, in said at least one secure connection request, a clienthello-type message of the transport layer security protocol,
for each identified clienthello-type message, automatically locating an indication of a name of said unsecure domain,
automatically obtaining said digital certificate for said unsecure domain from a trusted certification authority, said obtaining comprises:
(a) receiving a digital certificate identification (ID) code from the trusted certification authority, and
(b) placing the ID code onto said unsecure domain,

automatically associating said digital certificate with said unsecure domain, thereby converting said unsecure domain to a secure domain, and
automatically sending said digital certificate to at least one second client terminal in response to at least one future secure connection requests, thereby facilitating a secure connection between said at least one second client terminal and said secure domain,
wherein automatically means without any user intervention; and
at least one hardware processor configured to execute said processor instructions.

16. The computerized system of claim 15, wherein said processor instruction are further for determining that said client terminal is legitimate by counting a number of unique client terminals requesting said secure connection to said unsecure domain, wherein each said unique client terminal is determined to be associated with a legitimate client from parameters of said identified clienthello-type message.

17. The computerized system of claim 15, wherein said processor instruction are further for comparing, based on a certificate rule, said unsecure domain with a list of domains that are each associated with a client rule function, wherein said client rule function is a function of a plurality of client terminal parameters associated with said at least one client terminal.
