A network engineer configured new firewalls with the correct configuration to be deployed to each remote branch. Unneeded services were disabled, and all firewall rules were applied successfully. Which of the following should the network engineer perform NEXT to ensure all the firewalls are hardened successfully: A)Ensure an implicit permit rule is enabled. B)Configure the log settings on the firewalls to the central syslog server. C)Update the firewalls with current firmware and software. D)Use the same complex passwords on all firewalls.
The correct answer is C) Update the firewalls with current firmware and software.
After configuring the firewalls with the correct settings and disabling unneeded services, the network engineer should update the firewalls with current firmware and software.
This is an important step to ensure that the firewalls are running the latest versions, which often contain bug fixes, security patches, and performance improvements. Regularly updating the firmware and software reduces the risk of potential vulnerabilities and ensures the firewalls are operating at their optimal level.
Option A) Ensure an implicit permit rule is enabled is not necessary in this scenario. Implicit permit rules can introduce security risks as they allow traffic by default, and it’s generally recommended to have explicit rules that explicitly permit only necessary traffic.
Option B) Configure the log settings on the firewalls to the central syslog server is a good security practice, but it is not directly related to hardening the firewalls. It is more for monitoring and analysis purposes.
Option D) Using the same complex passwords on all firewalls is not recommended as it can be a security risk. If an attacker manages to discover one password, they would have access to all firewalls. Instead, it is best to use unique, complex passwords for each firewall and follow proper password management practices.
