6. Security features of operating systems

Modern operating systems have powerful built-in security tools that authenticate, authorize, audit users' actions in the system, protect against failures, cryptographic protection of operating system objects, and prevent network attacks. Let's take a closer look at the built-in security features of the most popular operating systems.

6.3. Conclusion

Modern operating systems have built-in security features that allow for effective authentication, authorization and audit of user actions. These tools can be the basis for the implementation of security policies. However, the built-in tools of operating systems alone are not enough to resolve all security issues, they need to be supplemented with specialized software (antivirus software, firewalls, etc.).
