Let’s learn how to turn on Windows Device Protection with Core Isolation Memory Integrity. Memory integrity is a feature of core isolation. Turning on the Memory integrity setting can help prevent malicious code from accessing high-security processes in the event of an attack.
Windows Security provides built-in security options to help protect your device from malicious software attacks. Core isolation is a security feature of Microsoft Windows that protects important core processes of Windows from malicious software by isolating them in memory.
Memory integrity prevents attacks from inserting malicious code into some Windows Core processes. It does this by virtualizing some of those processes, which results in the processes being isolated from other parts of memory.
Memory integrity, also known as Hypervisor-protected Code Integrity (HVCI) is a Windows security feature that makes it difficult for malicious programs to use low-level drivers to hijack your computer.
Microsoft is continuously investing in improving the default security baseline for Windows. In the future update of Windows 11, you’re going to many security features for Windows that will help protect hybrid work, with the great addition. Here’s a look at New Security Features for Windows 11.
