Detecting Unauthorized Web Servers

A technician has been alerted of incoming HTTP traffic on the LAN segment that should not contain any web servers.

The technician has the IP address of the destination host and wants to determine if the socket for HTTP is open.

Which of the following should the technician perform?

A.

Baseline assessment

B.

Packet analysis

C.

Port scan

D.

Patch-level assessment.

C.

The best option for the technician to determine if the socket for HTTP is open on the destination host is to perform a port scan, which is option C.

A port scan is a network reconnaissance technique used to identify which ports are open and listening on a target device. Ports are used to establish network connections and transmit data between devices. In this case, the technician wants to determine if port 80, which is the default port used for HTTP traffic, is open on the destination host.

A baseline assessment, which is option A, is a comparison of current network performance against a previously established baseline to identify changes and potential issues. It is not directly related to identifying open ports.

Packet analysis, which is option B, is the process of examining network traffic at the packet level to identify issues or security threats. While packet analysis can help identify HTTP traffic, it does not directly provide information about open ports.

A patch-level assessment, which is option D, involves reviewing and updating software patches and updates on network devices to improve security and performance. It is not directly related to identifying open ports.

In summary, the best option for the technician to determine if the socket for HTTP is open on the destination host is to perform a port scan, which involves scanning for open ports on the device.
