OS Security Explained: Access Attacks & Access Control Models

How do operating systems decide who gets access to what—and how do attackers try to bypass those decisions? This comprehensive session breaks down the two sides of OS security: access attacks (credential compromise, password cracking, and impersonation) and access control models (DAC, MAC, RBAC, ABAC, Bell-LaPadula, Biba, Clark-Wilson, and more). Learn how real operating systems like Unix, Windows, Android, and iOS layer these models together to build defence in depth. Perfect for students, developers, and security professionals. Includes a practical payroll system scenario applying these concepts. #OSSecurity #AccessControl #CyberSecurity #InfoSec #DAC #MAC #RBAC #ABAC #OperatingSystems #CyberAware #TechTalk #SecurityModels #LeastPrivilege #LinuxSecurity #WindowsSecurity #CyberSecurityAwareness #AccessAttacks #ZeroTrust #IdentitySecurity
