Which of the following BEST ensures that a firewall is configured in compliance with an enterprise's security policy?
Click on the arrows to vote for the correct answer
A. B. C. D.D.
A review of the parameter settings will provide a good basis for comparison of the actual configuration to the security policy and will provide reliable audit evidence documentation.
Incorrect Answers: A: While interviewing the firewall administrator may provide a good process overview, it does not reliably confirm that the firewall configuration complies with the enterprise's security policy.
B: While procedures may provide a good understanding of how the firewall is supposed to be managed, they do not reliably confirm that the firewall configuration complies with the enterprise's security policy.
C: While reviewing the device's log file for recent attacks may provide indirect evidence about the fact that logging is enabled, it does not reliably confirm that the firewall configuration complies with the enterprise's security policy.
The best way to ensure that a firewall is configured in compliance with an enterprise's security policy is to review the parameter settings.
Explanation: Firewalls are an essential component of an enterprise's security infrastructure and are used to control access to and from the organization's network. It is crucial that firewalls are configured correctly to provide effective security and comply with the organization's security policy.
Option A, interviewing the firewall administrator, can provide useful information about the configuration process and can help to identify potential areas of concern. However, it is not a reliable method for ensuring that the firewall is configured in compliance with the enterprise's security policy.
Option B, reviewing the actual procedures, can provide useful information about how the firewall was configured. However, it does not guarantee that the firewall is configured correctly or in compliance with the enterprise's security policy.
Option C, reviewing the device's log file for recent attacks, is a useful method for identifying potential security breaches or anomalies. However, it is not a reliable method for ensuring that the firewall is configured in compliance with the enterprise's security policy.
Option D, reviewing the parameter settings, is the best way to ensure that a firewall is configured in compliance with an enterprise's security policy. The firewall's parameter settings can be compared against the organization's security policy to ensure that they meet the required standards. This approach is more reliable than other methods as it provides a direct assessment of the firewall's configuration and can identify areas of non-compliance that need to be addressed.
In conclusion, option D, reviewing the parameter settings, is the best approach to ensure that a firewall is configured in compliance with an enterprise's security policy.
