What is Memory Integrity and how does it works ?
Imagine your computer’s memory as a bustling marketplace. Programs (like vendors) set up shop, exchanging data and instructions.
In this scenario, memory integrity acts like a security guard in this marketplace, ensuring only authorized vendors operate and no one tampers with the goods.
Now, let’s take a deeper dive into memory’s integrity and how it works:
What is Memory Integrity?
First and foremost, memory integrity is a security feature available in Windows 10 and 11 that leverages hardware virtualization to create a secure environment for critical system processes.
Essentially, think of it as a special, isolated zone within your computer’s memory.
How Does it Work ?
There are two key aspects to memory’s integrity:
- Virtualization-Based Security (VBS): To begin with, this technology creates a virtual environment separate from the main operating system. As a result, critical system processes, like the ones that manage hardware and security, run within this isolated zone.
- Memory Protection: Additionally, memory integrity restricts unauthorized code from accessing these critical processes. Consequently, this makes it much harder for malware to infiltrate and take control of your system.
Here’s a step-by-step breakdown of how memory integrity protects your PC:
- Program Requests Access: Initially, a program running on your computer needs access to a specific area of memory.
- Memory Integrity Checks: Subsequently, the memory’s integrity feature intercepts this request and verifies the program’s legitimacy using a special set of rules.
- Access Granted (or Denied): Finally, if the program is authorized, memory’s integrity grants access. However, if it’s suspicious or malicious, access is denied, thus preventing it from interfering with critical system processes.
Benefits of Memory Integrity
- Enhanced Malware Protection: Firstly, it makes it significantly harder for malware to tamper with core system functions.
- Improved System Stability: Secondly, it protects critical processes from accidental crashes caused by incompatible software.
- Reduced Security Risks: Lastly, it provides an extra layer of defense against security vulnerabilities.
