Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Masquerading malicious traffic on common ports like 443
Why this is correct
Using standard ports makes malicious traffic blend in with web traffic.
- ✗
Using clear-text Telnet for all communication
Why it's wrong here
Telnet is easily detectable and rarely used for hiding traffic.
- ✗
Sending traffic exclusively during business hours
Why it's wrong here
This makes traffic look like user activity, but is not a method for 'hiding' the traffic itself.
- ✗
Disabling all logging on the source host
Why it's wrong here
This is an anti-forensics technique, not a way to hide network traffic.
- ✓
Embedding data within encrypted SSH tunnels
Why this is correct
SSH tunnels hide the actual traffic content from NIDS.
