ABE is commonly used in Windows File Services, SharePoint environments, and enterprise conte..."
  • 06:3506:35, 6 July 2026 diff hist +10,791 N Least Privilege Access Created page with "'''Summary:''' Least Privilege Access (sometimes called the ''Principle of Least Privilege'' or ''PoLP'') is a security model that restricts users, systems, applications, and services to the minimum permissions required to perform their intended function. Rather than granting broad access "just in case", permissions are carefully assigned based on business need, operational responsibility, and security requirements. This reduces the impact of mistakes, limits opportuni..." current
  • 06:3306:33, 6 July 2026 diff hist +8,615 N Defence in Depth Created page with "'''Summary:''' Defence in Depth is a security strategy that uses multiple, independent layers of protection to reduce risk. Rather than relying on a single security control, organisations deploy overlapping preventative, detective, and corrective measures throughout their infrastructure. The approach assumes that any individual security control can fail, be bypassed, misconfigured, or become obsolete. By introducing multiple protective layers, an attacker who defeats o..." current
