Comprehensive Guide to Information Security Models: Principles, Types, and Implementation (PDF Resources)
An information security model is a framework that outlines the policies, procedures, and guidelines for protecting an organization's information assets from various threats. It's a systematic approach to managing information security risks and ensuring the confidentiality, integrity, and availability of sensitive information. An effective information security model helps organizations to identify, assess, and mitigate potential security risks, as well as ensure compliance with regulatory requirements.
Contextual factors (e.g., current time, geographic location, device security posture). If you’d like
Limit user access with Just-In-Time (JIT) and Just-Enough-Access (JEA) models to protect data and mitigate lateral movement.
