two-factor authentication. Two-factor authentication (2FA) is a security measure that requires users to provide two pieces of evidence to verify their identity before accessing SaaS-based applications1. These pieces of evidence can be something the user knows (such as a password or a PIN), something the user has (such as a smartphone or a token), or something the user is (such as a fingerprint or a face scan)1. 2FA enhances the security of SaaS-based applications by making it harder for attackers to compromise login credentials and gain unauthorized access to sensitive data and resources2. The other options are not correct because they are not sufficient to secure SaaS-based applications. Modular policy framework (MPF) is a feature of Cisco ASA that allows administrators to create and apply security policies to traffic flows3. However, MPF alone cannot protect SaaS-based applications from web-based threats or data breaches. Application security gateway (ASG) is a device that provides firewall, intrusion prevention, and content filtering services for web applications4. However, ASG cannot prevent credential theft or account takeover attacks that target SaaS- based applications. End-to-end encryption (E2EE) is a method of encrypting data in transit and at rest, so that only the sender and the receiver can decrypt it. However, E2EE cannot prevent unauthorized access to SaaS- based applications if the encryption keys are compromised or stolen. References:

DevSecOps (development, security, and operations) is a concept used in recent years to describe how to move security activities to the start of the development life cycle and have built-in security practices in the continuous integration/continuous deployment (CI/CD) pipeline. Thus minimizing vulnerabilities and bringing security closer to IT and business objectives.
Three key things make a real DevSecOps environment:
+ Security testing is done by the development team.
+ Issues found during that testing is managed by the development team.
+ Fixing those issues stays within the development team.
