CYBERSECURITY AND INFORMATION ASSURANCE Provide answers to the mitigation of the following description
22. Weak Authentication Scheme [State: Not Started] [Priority: High]
Category:Information Disclosure
Description: Custom authentication schemes are susceptible to common weaknesses such as weak credential change management, credential equivalence, easily guessable credentials, null credentials, downgrade authentication, or a weak credential change management system. Consider the impact and potential mitigations for your custom authentication scheme.
Justification:
23. Replay Attacks [State: Not Started] [Priority: High]
Category:Tampering
Description: Packets or messages without sequence numbers or timestamps can be captured and replayed in a wide variety of ways. Implement or utilize an existing communication protocol that supports anti-replay techniques (investigate sequence numbers before timers) and strong integrity.
Justification:
24. Collision Attacks [State: Not Started] [Priority: High]
Category:Tampering
Description: Attackers who can send a series of packets or messages may be able to overlap data. For example, packet 1 maybe 100 bytes starting at offset 0. Packet 2 maybe 100 bytes starting at offset 25. Packet 2 will overwrite 75 bytes of packet 1. Ensure you reassemble data before filtering it, and ensure you explicitly handle these sorts of cases.
