Explanation:
Since each firewall is different, you will need to read and understand the documentation that comes with it to determine whether the default firewall settings are sufficient for your needs. This is particularly concerning because the “default” configuration is typically less restrictive, which could make your firewall more susceptible to compromise. Alerts about current malicious activity (e.g., CISA’s Alerts) sometimes include information about restrictions you can implement through your firewall.
