Best Way to Evaluate Access Controls to an Internal Network

A.

Access controls are crucial for securing an internal network, and it's essential to evaluate their effectiveness to ensure the security of the network. Each of the options provided in the question can be used to evaluate access controls, but the BEST way to evaluate their effectiveness is to perform a system penetration test.

Explanation of each option: A. Perform a system penetration test: This is the BEST option as it involves simulating an attack on the network to identify vulnerabilities in the access controls. A penetration test can identify weaknesses that are not apparent from a review of access rights or router configurations, and it can provide a more comprehensive assessment of the effectiveness of the access controls.

B. Test compliance with operating procedures: This option involves reviewing the procedures in place to ensure that they are being followed. It can help to identify gaps in procedures or areas where training may be needed, but it may not reveal all weaknesses in the access controls.

C. Review access rights: This option involves reviewing the permissions granted to users and ensuring that they are appropriate. While this is a necessary step in evaluating access controls, it may not reveal all the weaknesses in the system.

D. Review router configuration tables: This option involves reviewing the configuration of the routers that control access to the network. While this is a necessary step in evaluating access controls, it may not reveal all the weaknesses in the system.

In conclusion, performing a system penetration test is the BEST way to evaluate the effectiveness of access controls to an internal network. It can identify weaknesses that other methods may miss and provide a comprehensive assessment of the security of the network.
