Microsoft’s new kernel information safety know-how for Home windows 10 will make kernel reminiscence read-only
Within the fixed battle towards hackers, Microsoft has simply performed one other card, introducing new kernel information safety know-how that may make it more durable for attackers to make use of information corruption methods to bypass safety and enhance privileges.
Kernel Knowledge Safety (KDP) makes sections of kernel reminiscence read-only and prevents information corruption assaults by defending components of Home windows kernel and drivers by means of virtualization-based safety (VBS).
The know-how is claimed to mitigate a brand new type of assault seen just lately, the place hackers exploit signed however susceptible drivers to put in malicious unsigned drivers which then corrupt reminiscence. With read-only safety, even signed drivers wouldn’t have the ability to modify essential reminiscence constructions and parameters.
Microsoft has mentioned the know-how is required to maintain attackers at bay as hackers develop annoyed with Code Integrity (CI) and Management Circulate Guard (CFG) safety applied sciences and search for different avenues of exploitation.
Microsoft says the know-how has different advantages, together with:
- Efficiency enhancements – KDP reduces the load on attestation parts, which might not have to periodically test for information variables which have been write protected
- Reliability Enhancements – KDP makes it simpler to diagnose reminiscence corruption bugs that do not essentially signify safety vulnerabilities
- Have interaction builders and driver distributors to enhance compatibility with virtualization-based safety, bettering adoption of those applied sciences throughout the ecosystem
Not all Home windows techniques will have the ability to implement KDP as a result of the platform should assist virtualization-based safety (VBS). The know-how is already accessible within the newest Insider variations of Home windows 10.
