In real-world environments, attackers keep looking for unpatched software and misconfigurations to gain an opportunity for remote code execution. Once code execution is achieved, a simple technical glitch becomes an active intrusion.<\/p>\n<p>Proactive detection is a crucial part of any RCE defense strategy. However, detecting RCE attacks is not easy because malicious activity easily blends into legitimate application behavior.<\/p>\n<p>In this article, we cover how to detect and prevent remote code execution attacks using a combination of engineering practices and security platforms like <a href=\"https:\/\/fidelissecurity.com\/fidelis-elevate-extended-detection-and-response-xdr-platform\/\">Fidelis Elevate<\/a>\u00ae and <a href=\"https:\/\/fidelissecurity.com\/fidelis-halo-cloud-native-application-protection-platform-cnapp\/\">Fidelis CloudPassage Halo<\/a>\u00ae.<\/p>\n<\/div>\n<\/div>\n<div class=\"elementor-element elementor-element-8d2067d elementor-widget elementor-widget-heading\">\n<div class=\"elementor-widget-container\">\n<h2 class=\"elementor-heading-title elementor-size-default\">Why is RCE Detection Hard?<\/h2>\n<\/div>\n<\/div>\n<div class=\"elementor-element elementor-element-d35c97c elementor-widget elementor-widget-text-editor\">\n<div class=\"elementor-widget-container\">\n<p>RCE is difficult to detect because they are designed to look normal and legitimate.
