System monitoring can detect unauthorized use of organizational systems. System monitoring is an integral part of continuous monitoring and incident response programs. Monitoring is achieved through a variety of tools and techniques (e.g., intrusion detection systems, intrusion prevention systems, malicious code protection software, scanning tools, audit record monitoring software, network monitoring software). Output from system monitoring serves as input to continuous monitoring and incident response programs.<br \/>\nUnusual\/unauthorized activities or conditions related to inbound and outbound communications traffic include internal traffic that indicates the presence of malicious code in systems or propagating among system components, the unauthorized exporting of information, or signaling to external systems. Evidence of malicious code is used to identify potentially compromised systems or system components. System monitoring requirements, including the need for specific types of system monitoring, may be referenced in other requirements.<br \/>\nNIST SP 800-94 provides guidance on intrusion detection and prevention systems.<\/p>\n<p>Further Discussion<br \/>\nDefine authorized use of your systems. Create an acceptable use policy to establish the baseline for how users access devices, internal network services, and the internet. Define authorized use by specific roles such as: user, administrator, and technician. After authorized use is defined, identify unauthorized use of systems.<br \/>\nMonitor systems by observing audit activities from the system logs. This can be accomplished in real time using automated solutions or by manual means. To identify unauthorized use, leverage existing tools and techniques, such as:<\/p>\n<ul>\n<li>intrusion detection systems;\n<li>intrusion prevention systems;\n<li>malicious code protection software;\n<li>scanning tools;\n<li>audit record monitoring software; and\n<li>network monitoring software.<\/li>\n<\/ul>\n<p>This requirement, SI.L2-3.14.7, which deals with identifying unauthorized use of organizational systems, is related to requirements: AC.L2-3.1.1, AU.L2-3.3.1, IA.L2-3.5.1, and IA.L2-3.5.2.
