Practical Guide to Securing Windows 11 Devices

This guide outlines ten essential security strategies for Windows 11 devices aimed at security administrators, SOC teams, and MSPs. It emphasizes the importance of keeping devices and applications updated to mitigate risks and enforce policy compliance. Key strategies include restricting local administrator privileges, securing local admin passwords with Windows LAPS, and encrypting devices using BitLocker and Personal Data Encryption (PDE). The document details how patching can prevent cyberattacks by addressing known vulnerabilities in software. It also discusses the significance of implementing least privilege access to reduce the risk of lateral movement and privilege escalation in attacks. Additionally, the guide highlights the role of Attack Surface Reduction (ASR) rules in blocking risky processes and preventing exploits that utilize built-in tools. Each section provides implementation tips and explains the security impact of the measures discussed, reinforcing the necessity of a comprehensive approach to device security.
