Firewalls filter traffic based on rules set by the administrator. These rules can be based on IP addresses, port numbers, protocols, and more.
Firewalls provide logging and monitoring capabilities to help administrators track and analyze security events and trends.
Firewalls often support Virtual Private Network (VPN) connections to securely connect different parts of the network over the Internet.
Firewalls can track the state of active connections and make decisions based on the context of the traffic.
Keep firewall rules and signatures up to date to protect against the latest threats.
Limit access to firewall management interfaces to authorized personnel only and use strong authentication methods.
Implement multiple layers of security (defense in depth) to protect cloud resources. Combine network-based firewalls with host-based firewalls and other security measures.
Conduct regular audits to ensure firewall configurations comply with organizational policies and regulatory requirements.
Establish comprehensive security policies that define which traffic is allowed and which is denied.
