Question

You recently learned that a network router has TCP ports 22 and 80 open, but the organization's security policy mandates that these should not be accessible. What should you do?

A) Disable the FTP and HTTP services on the router.
B) Disable the DNS and HTTPS services on the router.
C) Disable the SSH and HTTP services on the router.
D) Disable the Telnet and Kerberos services on the router.

Answer 1

To comply with the security policy, you should disable the SSH and HTTP services on the router.

Step-by-step explanation:

The correct answer is C) Disable the SSH and HTTP services on the router.

TCP port 22 is used for Secure Shell (SSH) which provides secure remote login and file transfer capabilities. TCP port 80 is used for Hypertext Transfer Protocol (HTTP) which is the protocol used by web browsers to communicate with web servers. Disabling these services on the router will make sure that they are not accessible.

For example, to disable SSH on the router, the administrator can access the router's configuration settings and disable the SSH service or block traffic on port 22. Similarly, the HTTP service can be disabled or traffic on port 80 can be blocked.
