✍️ Sample CSS Questions & Answers
1. Which cloud deployment model provides an organization with the highest level of control over its infrastructure?
A private cloud is dedicated exclusively to one organization, granting the greatest control over security configurations and infrastructure.
2. Which indicator in endpoint telemetry MOST strongly suggests process injection has occurred?
Process injection hijacks trusted processes, so suspicious network behavior or unusual child processes spawned by normally benign system processes is a strong indicator.
3. Which attack targets authentication systems by using previously captured valid authentication tokens?
Pass-the-hash and pass-the-ticket attacks use stolen authentication tokens to authenticate as a victim without knowing the actual password.
4. What is the first step in incident response?
The first and most crucial step in incident response is to accurately identify that a security incident has occurred and then thoroughly assess its nature, scope, and severity. This initial phase, often called detection and analysis, is vital for understanding the situation, determining the appropriate response actions, and allocating resources effectively before proceeding to subsequent steps like containment or eradication.
5. Which technique allows an attacker to bypass network-based intrusion detection by splitting a TCP packet payload across multiple fragments?
Splitting a malicious payload across fragmented packets can evade IDS/IPS systems that do not properly reassemble TCP streams before inspecting content.
6. Which stakeholder group is MOST critical to include during the initial development of an enterprise information security policy?
Senior leadership provides authority and strategic alignment, while legal counsel ensures regulatory compliance — both are essential at the policy creation stage.
