What is a "security requirement"?

A "security requirement" refers to a specification that a system must satisfy to reduce vulnerabilities and mitigate risks. In the context of software development, security requirements are critical because they define the necessary controls and standards that need to be in place to protect the system from threats and breaches. These requirements ensure that the software not only functions correctly but also maintains the integrity, confidentiality, and availability of data within it.

By identifying and implementing robust security requirements during the software design process, developers can proactively address potential security issues before they become significant problems. This includes measures such as authentication, data encryption, and secure coding practices, all aimed at safeguarding the system against various types of attacks.

The options that focus on legal obligations, user experience, or guidelines for user support do not align with the core purpose of security requirements, which is to enhance the security posture of a software application rather than to fulfill legal obligations, improve usability, or assist users.
