Next Gen Firewall (NGFW) is a by default part of any IT setup of corporate / business houses for hosting their data and doing routine work. This article is intend to share some elementary guidelines to configure and manage NGFW. Though many of us are having these pointers are in place but felt that it can be useful for others especially who are working in this field.

·        Create a security policy: A security policy defines the rules and guidelines for access to your network. It should include information on what traffic is allowed or blocked, how traffic is monitored, and how security incidents are handled.

·        Limit incoming traffic: Only allow incoming traffic that is necessary for your business operations. Block all other incoming traffic.

·        Limit outgoing traffic: Limit outgoing traffic to only necessary traffic. This can help prevent malicious software from sending data out of your network.

·        Regularly review logs: Review firewall logs regularly to detect any unusual traffic patterns or potential security breaches.

·        Implement VPN: If remote access is required, use a VPN to securely connect remote users to your network.

·        Test and validate firewall rules: Regularly test and validate firewall rules to ensure that they are functioning as intended.

·        Regularly review security policies: Review security policies periodically to ensure they are up to date with the latest threats and to make any necessary changes.
