GSEC Defense in Depth Practice Question
Which TWO of the following are primary objectives of implementing a defense in depth strategy in a corporate environment?
⚠ Common exam trap
Candidates often select incorrect options that imply defense in depth can completely prevent all initial attacks or eliminate risk entirely, rather than merely increasing cost and resilience.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
To increase the difficulty and cost for an attacker to succeed.
Defense in depth aims to delay attackers, increase the probability of detection, and ensure that a single point of failure does not lead to a total security compromise. These objectives are achieved by creating layers that require an attacker to defeat multiple, distinct security measures. This approach is essential for modern enterprises where perimeter defenses can be bypassed via phishing or zero-day vulnerabilities, making internal detection and mitigation capabilities absolutely vital.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To eliminate the need for regular security patching.
Why it's wrong here
Defense in depth does not negate the necessity of vulnerability management or patching. Patching is a critical layer of defense that addresses the root cause of exploits. Relying on other layers to compensate for unpatched software is a flawed strategy that leaves the organization unnecessarily vulnerable to attacks.
- ✓
To increase the difficulty and cost for an attacker to succeed.
Why this is correct
By implementing multiple, heterogeneous layers of security, an organization forces an attacker to expend more time and resources. Each additional layer increases the complexity of the attack chain, raising the likelihood of detection and providing more opportunities for the security team to identify and stop the adversary.
- ✓
To ensure that a single control failure does not result in a breach.
Why this is correct
The core of defense in depth is redundancy. By ensuring that no single security measure is a single point of failure, the organization can contain threats. If a firewall is bypassed, host-based security or network segmentation serves as the next barrier to stop the attacker from moving laterally.
- ✗
To replace the requirement for user security awareness training.
Why it's wrong here
Human users are often the weakest link in the security chain. No amount of technical layering can fully protect against social engineering if users are not trained. Defense in depth is intended to complement, not replace, the human element of an organization's overall cybersecurity and risk posture.
- ✗
To centralize all logs into a single storage location.
Why it's wrong here
While centralized logging is a best practice for visibility, it is a management and monitoring capability, not a primary objective of defense in depth. Defense in depth focuses on the layered application of security controls to stop attackers, whereas logging is primarily a detective and forensic capability.
