Steps To Optimize Your Firewall Configuration

October 28, 2015

Firewall is an essential part of your organization’s network security. It works by monitoring all the incoming and outgoing traffic on your network to restrict any unauthorized access. It can also limit exposure by camouflaging internal network information from the public internet. Though its importance is well-known, many people do not optimize their firewall settings efficiently. Majority of the cyber-attacks occur mainly because of flaws in a network’s firewall configuration.

Here are some steps that you need to follow to optimize your firewall configuration:

  • Filter Outbound Traffic: You must constantly monitor your server to detect and remove any unwanted or unauthorized traffic. Denied or dropped outbound requests hitting the firewall should also be tracked. Subsequently, the network administrators should reconfigure the firewall to prevent such unauthorized servers, thereby eliminating load from the firewall.
  • Minimize Privileges: You should set specific configuration polices to filter traffic on your organization’s network. Each user should be given the least level of privileges that are absolutely required for him to work efficiently. This will reduce the chances of a potential data breach. You should also review your firewall policies frequently to determine any new applications and the connectivity they need
  • Run Only Required Services: Many organizations face security issues due to outdated or unrequired services running on their firewall. The best way to overcome this is to strengthen device security and ensuring that the firewall configurations are compliant before they can be used on the organization network. By modifying your device’s settings according to their functioning and usage, you can improve its security and minimize the chances of running a malicious service on your firewall.
  • Standardize Authentication Mechanisms: You should enforce the same authentication mechanisms across all your organization’s branches, even in remote locations. If not, the employees will be able to access online accounts with weak passwords without any limit on login failures on entering incorrect details. In such situations, hackers find an easy way to access the organization network through remote locations. Having a standardized authentication policy will minimize this risk and improve security.

It is important that you continuously monitor your organization’s firewall settings. However, by following these steps, you can improve overall network security and significantly lower the chances of a hacking attack.
