Cisco Cyber Security Practice Exam

If a router has a software vulnerability, what action is advisable?

1. Disconnect the router

2. Update device with security fixes and patches

3. Change the router password

4. Monitor incoming traffic

The correct answer is: Update device with security fixes and patches

Updating the device with security fixes and patches is advisable when a router has a software vulnerability because it directly addresses the specific weakness that could be exploited by cyber threats. Software vulnerabilities often arise from flaws in the router’s firmware or operating system, which can leave it open to unauthorized access or attacks. By applying security fixes and patches, you reinforce the router’s defenses, mitigate the risk of exploitation, and ensure that known vulnerabilities are resolved. Disconnecting the router may be an immediate response to prevent any potential attacks, but it does not solve the underlying issue of the vulnerability. Changing the router password is a good practice for enhancing security but does not address the software flaws that may allow an attacker to gain control of the device. Monitoring incoming traffic can help in identifying suspicious activity, but it is a reactive approach and does not resolve the vulnerability itself. Thus, updating the device with security fixes and patches is the most effective proactive measure to safeguard the router against potential threats.
