"Software Development Security — a MUST know for the CISSP exam."– Luke Ahmed
Today is Day 10 of Yihenew’s CISSP study plan, staying within Software Development Security, this time focusing on inference attacks and their role in protecting sensitive information.
Key Areas Covered:
Inference Attacks Defined — deducing sensitive data from non-sensitive data through logical reasoning
Real-World Example — attacker combines salary ranges with job titles to reveal exact compensation data
CISSP Context — highlights the importance of proper database design and query restrictions
Countermeasures — data suppression, query restrictions, noise and perturbation, and access controls
Manager’s Viewpoint — inference attacks are less about raw hacking and more about gaps in governance and oversight
In this CISSP study plan session, Yihenew emphasized that inference attacks test whether a security professional understands how data can leak indirectly. The exam often frames these questions from a risk management perspective, not just a technical one.
Quick CISSP Practice Question
Which of the following best describes an inference attack?
A. Exploiting unpatched vulnerabilities to access databases
B. Deducing restricted information by analyzing accessible data
C. Injecting malicious code to manipulate application behavior
D. Overwhelming systems to deny access to authorized users
✅ Correct Answer: B. Deducing restricted information by analyzing accessible data
Explanation: Inference attacks occur when an attacker pieces together available data to derive sensitive information. Unlike injection or DoS attacks, inference is indirect and often overlooked unless proper countermeasures are in place.
