Customers are unable to upload files to an SFTP server. Firewall logs show the following activity sourced from multiple IP addresses in one geographic region:

Time: 2024-10-11 15:05:21
Src_IP: 103.1.114.26
Dest_IP: 199.52.99.11
Src_port: 45678
Dest_port: 22
Action: Allow
Application: TCP
Src_zone: untrust
Dest_zone: trust
Session_end_reason: aged-out/incomplete

The analyst reviewing the logs notices that the session_end_reason does not change for any of the log entries. Which of the following is the next step the analyst should take to determine what is occurring?

الخيارات

  • A Submit a request to the engineering team to restart SFTP services on the host due to the session limit being reached.
  • B Take a packet capture of all traffic to or from dest_IP 199.52.99.11 to see whether it is responding to SYN-ACK with an ACK.
  • C Correct the misconfigured firewall by blocking dest_port 22 to prevent further credential brute-force attacks from src_IP 103.1.114.26
  • D Review endpoint detection logs on the SFTP server for any malware running on dest_port 22 that may be intercepting client communications.
