Hence, penetration testing is an evolving field. Here are some of the top trends, defenses and tactics to keep in mind:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Testing the external attack surface is necessary, as more assets are exposed to the internet and are regularly changing.<\/li>\n\n\n\n<li>Greater test frequency is needed to align with software development sprints.<\/li>\n\n\n\n<li>Penetration testing as a service (PTaas) provides integration with organizational defect tracking systems and can programmatically submit vulnerabilities to be tracked and remediated through the development team\u2019s defect tracking system.<\/li>\n\n\n\n<li>DevOps also needs to perform pentesting, as development and security have become intertwined.<\/li>\n\n\n\n<li>Automation should be used where possible to close the security gap and speed up the remediation process.<\/li>\n\n\n\n<li>Testing the supply chain is a necessary response to breaches such as SolarWinds and Kaseya.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Bottom Line: Open-Source Penetration Testing Tools<\/strong><\/h2>\n\n\n\n<p>Penetration testing is a critically important practice for keeping networks safe from intruders. While there are some <a href=\"https:\/\/www.esecurityplanet.com\/products\/best-penetration-testing\/\">comprehensive paid offerings<\/a>, many pentesting teams prefer the widely used open-source tools that they&#8217;re already familiar with. With a wide range of open-source tools to choose from, pentesters can accomplish comprehensive testing of their environments by using a number of free tools. But whether you use open-source tools, commercial tools, or even <a href=\"https:\/\/www.esecurityplanet.com\/networks\/vulnerability-management-as-a-service\/\">third-party services<\/a>, pentesting is something every organization with a network needs to do regularly.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Also read:<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.esecurityplanet.com\/applications\/open-source-vulnerability-scanners\/\">10 Best Open-Source Vulnerability Scanners for 2023<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.esecurityplanet.com\/networks\/nmap-vulnerability-scanning-made-easy\/\">Nmap Vulnerability Scanning Made Easy: Tutorial<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.esecurityplanet.com\/networks\/getting-started-with-burp-suite-pentest-tutorial\/\">Getting Started with the Burp Suite: A Pentesting Tutorial<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.esecurityplanet.com\/products\/metasploit-framework-tutorial\/\">Getting Started With the Metasploit Framework: A Pentesting Tutorial<\/a><\/li>\n<\/ul>\n\n\n\n<p><em>This updates a February 2022 article by <\/em><a href=\"https:\/\/www.esecurityplanet.com\/author\/jmaury\/\"><em>Julien Maury<\/em><\/a>.<\/p>\n\n\n<div id=\"ta-campaign-widget-66d6dd0807dfc-popup-wrapper\" class=\"ta-campaign-widget__popup-wrapper\">\n    \n<div\n    style=\"\n        --ta-campaign-plugin-primary: #3545ed;\n        --ta-campaign-plugin-button-text: #fff;\n        --ta-campaign-plugin-button-hover-background: #3231b4;\n        --ta-campaign-plugin-button-hover-text: #fff;\n        --ta-campaign-plugin-button-toggle-background: #3231b4;\n        --ta-campaign-plugin-button-toggle-text: #3231B4;\n    \"\n    data-ajax-url=\"https:\/\/www.esecurityplanet.com\/wp\/wp-admin\/admin-ajax.php\">\n    <div\n        id=\"ta-campaign-widget-66d6dd0807dfc\"\n        class=\"ta-campaign-widget ta-campaign-widget--popup\"\n        data-campaign-fields='{\"properties\":{\"campaign_type\":\"popup\",\"campaign_category\":false,\"sailthru_list\":[\"cybersecurity-insider\"],\"popup_type\":\"exit_intent\",\"appearance\":{\"colors\":{\"primary_color\":\"#3545ed\",\"button\":{\"button_text_color\":\"#fff\",\"hover\":{\"button_hover_background_color\":\"#3231b4\",\"button_hover_text_color\":\"#fff\"},\"toggle\":{\"button_toggle_background_color\":\"#3231b4\",\"button_toggle_text_color\":\"#3231B4\"}}},\"custom_scss\":\"\"},\"behavior\":{\"opt_in_enabled\":true},\"language\":{\"tagline\":\"Get the Free Cybersecurity Newsletter\",\"subtagline\":\"\",\"content\":\"Strengthen your organization&#39;s IT security defenses by keeping up to date on the latest cybersecurity news, solutions, and best practices.
