It can get a lot more technical than that, but it\u2019s all about identifying the weak points and ensuring the right defenses are in place.

Aspects like traffic analysis, configuration review, and updates for compliance purposes are all common focus areas.<\/span><\/p><p><span style=\"font-weight: 400;\">Although there\u2019s plenty that can be included in a network security audit, you\u2019re going to get a five-step breakdown.

A few examples of this would be your existing access control policies and current traffic. Something that shouldn\u2019t be missed here is the state of your data and security compliance.<\/span><\/p><p><span style=\"font-weight: 400;\">For a comprehensive start on your audit, information that spans from policy to configuration should be collected. You want to have a visible overview of the situation so you can approach any necessary changes from a bird\u2019s eye view.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8e9ef05 elementor-widget elementor-widget-heading\" data-id=\"8e9ef05\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">2.

These play a significant role in your network security. You can take this even further by looking into network segmentation. If you isolate specific data or internal systems, you can have a better chance of preventing later cyber attacks across your network.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-19460ee elementor-widget elementor-widget-heading\" data-id=\"19460ee\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">3.

This is crucial for anomaly detection as well as being proactive in identifying potential and existing threats.<\/span><\/p><p><span style=\"font-weight: 400;\">Other important aspects of analyzing your firewall device traffic logs include:<\/span><\/p><ul><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Review of traffic filtering is aligned with current security policies<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Making sure that logging mechanisms are capturing every traffic source<\/span><\/li><li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Maintaining compliance with security and data laws and regulations<\/span><\/li><\/ul><p><span style=\"font-weight: 400;\">Keeping a close eye on your traffic logs should be a fairly consistent practice.

Some of these practices overlap with other steps, but this step should also get its own focus.<\/span><\/p><p><span style=\"font-weight: 400;\">Nowadays, you can use the help of automation to scan your network for these kinds of issues. This coincides with penetration testing as well. It doesn\u2019t hurt to simulate real cyber threats to see how your firewall hardware will respond. The same goes for your network as a whole, and this section is equally important for overall risk mitigation, including compliance.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-bddd32a elementor-widget elementor-widget-heading\" data-id=\"bddd32a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">5.
