Worked practice questions

Suspicious application commands often originate from DoS attacks, malware and:

  1. Buffer overhangs
  2. Buffer overlaps
  3. Buffer overflows
  4. Buffer overloads
Show answer and solution

Correct answer: C. Buffer overflows

1. Several attack families reach the application protocol. 2. One of them abuses memory handling in the target. 3. Suspicious commands often originate from buffer overflow attacks, DoS attacks and malware. 4. So the answer is buffer overflows. _Source: NIST SP 800-41 Rev. 1, 'Guidelines on Firewalls and Firewall Policy'_

Besides signature based analysis, IDPSs also use which kind of analysis?

  1. Advisory based
  2. Assembly based
  3. Authority based
  4. Anomaly based
Show answer and solution

Correct answer: D. Anomaly based

1. A signature only matches an attack already known. 2. Detecting the unknown needs a different approach. 3. IDPSs also use signature-based and anomaly-based analysis to detect problems in network traffic. 4. So the answer is anomaly based. _Source: NIST SP 800-41 Rev. 1, 'Guidelines on Firewalls and Firewall Policy'_
