Microsoft Security Baselines: Security Review for Microsoft Edge Version 145

Microsoft has published its security review for Microsoft Edge version 145, detailing the security baselines and protections implemented in this latest browser release. The review comes as part of Microsoft's ongoing commitment to enterprise security and vulnerability management across its software ecosystem.

The security review focuses on several key areas of Edge version 145, including the browser's sandbox architecture, extension security model, and integration with Windows security features. Microsoft engineers conducted extensive penetration testing and code analysis to identify potential attack vectors and implement appropriate mitigations.

One of the primary improvements in Edge 145 relates to the browser's process isolation model. Microsoft has refined the sandbox boundaries between renderer processes and the browser's privileged components, reducing the attack surface for potential exploits. The review notes that these changes were informed by recent threat intelligence and attack patterns observed in the wild.

Extension security has also received significant attention in this release. Microsoft has implemented stricter validation rules for extension manifests and tightened the permissions model to prevent malicious extensions from accessing sensitive user data. The review highlights new controls that allow enterprise administrators to more granularly manage extension permissions across their organizations.

For enterprise environments, Edge 145 introduces enhanced Group Policy support and configuration options. The security baselines document provides detailed guidance on recommended settings for different deployment scenarios, from small businesses to large enterprises with complex security requirements.

The review also addresses compatibility considerations, noting that while the security improvements may affect certain legacy web applications, Microsoft has provided tools and guidance to help organizations identify and remediate potential issues before deployment.

Microsoft emphasizes that these security baselines are part of a continuous improvement process, with regular updates planned as new threats emerge and security best practices evolve. Organizations are encouraged to subscribe to Microsoft's security update notifications to stay informed about critical changes and recommendations.

For organizations planning to deploy Edge 145, Microsoft recommends following the security baselines outlined in the review and conducting their own validation testing in controlled environments before broad deployment. The company also provides enterprise support channels for organizations requiring additional assistance with security configuration and deployment planning.

The full security review document is available on Microsoft's official documentation site, providing detailed technical specifications and implementation guidance for security professionals and IT administrators.
