Question 850
At the Nortonwood online learning platform, an incident investigator concludes all SSH file transfers are harmless because the payload is encrypted. Which explanation best accounts for the concern?
Explanation
Correct Answer
The situation shows that encrypted SSH sessions can carry data exfiltration despite hiding payload contents, rather than merely a monitoring or presentation issue. Remediation is to analyze destination authorization flow volume timing and endpoint file activity for SSH SCP or SFTP.
Incorrect Answers
The offered principle is: DNS can carry encoded outbound data through a nominal name resolution channel. In the source material it is associated with: DNS can carry encoded outbound data through a nominal name resolution channel. This case has a different controlling cause: Encrypted SSH sessions can carry data exfiltration despite hiding payload contents. Its keyed mechanism is: Encrypted SSH sessions can carry data exfiltration despite hiding payload contents.
Although mAB is a fallback identifier method not strong cryptographic device authentication, the presented symptoms do not support that as the primary cause; they indicate that encrypted SSH sessions can carry data exfiltration despite hiding payload contents. For the Nortonwood online learning platform, the direct corrective action is to analyze destination authorization flow volume timing and endpoint file activity for SSH SCP or SFTP.
An endpoint's MAC connectivity does not establish its type and intended privilege. That may occur elsewhere, but the evidence at the Nortonwood online learning platform instead points to the fact that encrypted SSH sessions can carry data exfiltration despite hiding payload contents.
