CISSP Cheat Sheet

• Division D – Minimal Protection • Division C – Discretionary Protection − C1 – Discretionary Security Protection • Identification and authentication Separation of users and data • Discretionary protection of resources − C2 – Controlled Access Protection More finely grained DAC Individual accountability through login procedures • Object reuse • Protect audit trail Resource isolation Required System Documentation and user manuals.

• Division B – Mandatory Protection − B1 – Labeled Protection • Labels and mandatory access control • Process isolation in system architecture • Design specifications and verification • Device labels Informal statement of the security policy model Data sensitivity labels Mandatory Access Control (MAC) over select subjects and objects Label exportation capabilities All discovered flaws must be removed or otherwise mitigated Design specifications and verification − B2 – Structured Protection -Config Mgt* • Device labels and subject sensitivity labels • Trusted path • Separation of operator and administrator functions* • Covert channel analysis Security policy model clearly defined and formally documented DAC and MAC enforcement extended to all subjects and objects Covert storage channels are analyzed for occurrence and bandwidth Carefully structured into protection-critical and non-protection-critical elements Design and implementation enable more comprehensive testing and review Authentication mechanisms are strengthened Trusted facility management is provided with administrator and operator segregation Strict configuration management controls are imposed − B3 – Security Domains • Security administrator role defined* • Trusted recovery* • Monitor events and notify security personnel Satisfies reference monitor requirements Structured to exclude code not essential to security policy enforcement Significant system engineering directed toward minimizing complexity Security administrator role defined Audit security-relevant events Automated imminent intrusion detection, notification, and response Trusted system recovery procedures Covert timing channels are analyzed for occurrence and bandwidth An example of such a system is the XTS-300, a precursor to the XTS-400

• Division A – Verified Protection (very few) − A1 – Verified Design • Formal methods of design and testing Functionally identical to B3 Formal design and verification techniques including a formal top-level specification Formal management and distribution procedures
