Which security feature in modern CPUs protects memory areas that contain part of the operating system from malware attacks?TPMexecute disable bitLoJackencryption

What mechanisms do modern operating systems implement to enhance security and protect against malicious attacks, and how do these mechanisms function?Group of answer choices• (a) Modern operating systems use fixed memory allocation and static user permissions to enhance security by simplifying system management.• (d) Modern operating systems use legacy security models that emphasize physical isolation and hardware-based protection.• (c) Modern operating systems rely solely on antivirus software and firewalls to protect against malicious attacks, focusing on external threat prevention.• (b) Modern operating systems enhance security through mechanisms such as address space layout randomization (ASLR), data execution prevention (DEP), and user access controls. ASLR randomizes memory addresses to prevent predictable attacks, DEP prevents execution of code in non-executable memory regions, and access controls manage user permissions.• (e) Modern operating systems enhance security by integrating biometric authentication and eliminating traditional password-based access controls.
