✍️ 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 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.
3. 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.
4. What is the security benefit of using software-defined networking (SDN) in enterprise environments?
SDN's centralized control plane allows security policies to be applied uniformly across the network and updated dynamically in response to threats.
5. Which IAM control helps prevent privilege escalation by ensuring users cannot grant themselves higher permissions than they currently hold?
Constrained delegation and IAM permission boundaries ensure that even if an account is compromised, the attacker cannot escalate to permissions beyond those already assigned.
6. Which key management practice ensures that encryption keys are protected from the data they encrypt?
An HSM is a dedicated hardware device that stores and processes cryptographic keys in a tamper-resistant environment, separate from the data.
