Cisco Cyber Security Practice Exam

Which method is effective for managing unauthorized network probing and port scanning?

1. Conduct post-configuration penetration tests

2. Install additional software on all devices

3. Regularly refresh all hardware

4. Limit internet access for all employees

The correct answer is: Conduct post-configuration penetration tests

Conducting post-configuration penetration tests is an effective method for managing unauthorized network probing and port scanning because it simulates the actions of potential attackers to identify vulnerabilities within a network configuration. By performing these tests, security teams can analyze how well their defenses hold up against port scanning and probing attempts. This proactive approach allows organizations to uncover and remediate weaknesses before they can be exploited by malicious actors. This method also engages security personnel in a hands-on exercise that fosters a better understanding of actual hacking techniques and tools, contributing to the development of more robust security measures. By regularly scheduling penetration tests after significant changes or configurations, organizations can ensure their security posture remains strong against emerging threats. In contrast, while installing additional software might seem beneficial for security, it doesn't directly address how to defend against probing or scanning attempts. Regularly refreshing hardware can be good practice but does not principally aid in managing unauthorized access attempts. Limiting internet access for employees may mitigate some risks but can also hinder productivity and may not effectively address the core issue of unauthorized probing and scanning actions on the network.
