So it Mint Sandstorm subgroup has demonstrated its ability to quickly follow freshly claimed N-day vulnerabilities toward the playbooks. To help reduce organizational coverage, Microsoft Defender having Endpoint consumers can use the newest issues and you can vulnerability administration capacity to see, prioritize, and you can remediate vulnerabilities and you may misconfigurations.
Decreasing the attack surface
Microsoft 365 https://kissbrides.com/american-women/garland-ks/ Defender users may turn on attack body reduction guidelines to help you harden their surroundings against processes utilized by which Mint Sandstorm subgroup. These types of laws, and that’s set up because of the the Microsoft Defender Anti-virus people and not simply men and women making use of the EDR service, bring tall coverage resistant to the tradecraft discussed within report.
