"a computer emergency response team is called at midnight to investigate a case in which a mail server was restarted. after an initial investigation, it was discovered that email is being exfiltrated through an active connection. which of the following is the next step the team should take? a. identify the source of the active connection b. perform eradication of active connection and recover c. performance containment procedure by disconnecting the server d. format the server and restore its initial configuration"
Answer: B. Identify the source of the active connection
Any problem can be fixed only finding of the source of it. We can fix a problem in ‘n’ number of ways but it might again come back if source of it is not identified.
Identify the source of the active connection is the NEXT step the team should take. It is very similar to our human body.
If the infection is coming in the body again and again and gets fixed in the treatment, the reason for come - back will be identified so that it does not lead to unnecessary treatment.
In a similar way, if source are identified then the problem of come-back can be avoided. So option B would be the right choice.
