## 3 Proposed Framework for Cloud Multi-Factor Multi-Layer Authentication
### Cloud MFA Algorithm for Intrusion Detection
The objective of integrating multi-factor authentication methods on cloud is to enhance the security of cloud platforms and reduce false alarms. By using multiple authentication factors, it is more difficult for intruders to violate the system. The framework described in the abstract uses a variety of authentication factors, including the length, validity, value, suspected table, geolocation, and browser name of the authentication factor. By checking all of these factors, the framework can help to maintain that only authorized users can access the system. Using a combination of different security approaches is the optimal way to secure the systems and data from attack. This is because no single security approach is perfect, and attackers are constantly developing new ways to exploit vulnerabilities. By using a combination of approaches, the attackers and malicious users will find it more difficult to access cloud computing resources. The best way to detect malicious users and intruders is to use a combination of different approaches. By using multiple authentication factors and monitoring user activity, the system can make it more difficult for attackers to access the system and disclose data. The best combination of security approaches for your organization will depend on your specific needs and risks. The major benefits of integrating multi-factor authentication methods on cloud are as follows. 1. Increased security: multi-factor authentication makes it more difficult for intruders to access the system, even if they have stolen one of the user's authentication factors. 2. Reduced false alarms: By using multiple authentication factors, the framework can help to reduce the number of false alarms. This is because it is less likely that an intruder will be able to provide all of the required authentication factors. 3. Improved user experience: Multi-factor authentication can also improve the user experience. This is because users only need to provide their authentication factors once, when they first log in to the system. After that, they can access the system without having to provide their authentication factors again.

Reduced risk of data breaches: A combination of security approaches can help to reduce the risk of data breaches by making it more difficult for attackers to gain access to your systems and data. 6. Improved compliance: Many industry regulations require organizations to implement a combination of security approaches. By using a combination of approaches, you can help to ensure that your organization is compliant with all applicable regulations. Overall, the integration of multi-factor authentication methods in the cloud can provide a number of benefits, including increased security, reduced false alarms, and improved user experience. Different research methodologies are used to limit data access and provide provable security measures. As presented in [87], the authors proposed a new method for fine-grained data access control in mobile cloud computing (MCC)-based healthcare applications. The method is designed to be provably secure and to provide fine-grained control over data access, while also being efficient and scalable. As presented in [88], a new three-factor authentication, and key agreement protocol (CT-AKA) for cloud-assisted vehicles is proposed. The paper begins by discussing the security challenges of cloud-assisted AVs. These challenges include the need to protect the privacy of AV users, the need to ensure the security of AV communications, and the need to prevent malicious attacks on AVs. The paper then presents the proposed CT-AKA protocol, which is based on a combination of three-factor authentication, fuzzy vault cryptography, and key agreement.
