Shared Responsibility Model: ISC2 CC Deep Dive

The Shared Responsibility Model defines the security obligations of the cloud provider and the customer. In IaaS, customers manage most of the stack; in PaaS, the provider handles more; and in SaaS, the provider manages nearly everything. Regardless of the model, the customer always remains responsible for their own data and identity management.

Digital Signatures & Non-Repudiation: ISC2 CC Guide

Digital signatures use asymmetric encryption to ensure message authenticity, integrity, and non-repudiation. By encrypting a hash of a message with a private key, the sender creates a unique signature that anyone with the corresponding public key can verify, proving the sender's identity and that the content remained unchanged.

Vulnerability Scanning vs Pen Testing: Key Differences

Vulnerability scanning is an automated, frequent process that identifies known security flaws without exploiting them. Penetration testing is a manual, deep-dive simulation of a real-world attack that actively exploits vulnerabilities to test defenses. While scanning finds the "open door," pen testing actually walks through it to assess the real impact.

Least Privilege vs Need to Know: ISC2 CC Study Guide

Least Privilege (PoLP) restricts a user's access to the minimum set of permissions required to perform their job function. Need to Know further narrows this by limiting access to specific data based on a legitimate requirement. Together, these access control models minimize the attack surface and prevent unauthorized lateral movement.
