Control system security
open-in-new
<p>Control system security, or automation and control system (ACS) cybersecurity, is the prevention of (intentional or unintentional) interference with the proper operation of <a href="/facts/Automation/3YlF2K5q">industrial automation</a> and <a href="/facts/Industrial_control_systems/YzgsMy2x">control systems</a>. These control systems manage essential services including electricity, petroleum production, water, transportation, manufacturing, and communications. They rely on computers, networks, operating systems, applications, and <a href="/facts/Programmable_logic_controller/bqh0GAdb">programmable controllers</a>, each of which could contain <a href="/facts/Vulnerability_(computing)/jg0Gr71M">security vulnerabilities</a>. The 2010 discovery of the <a href="/facts/Stuxnet/xa7gvYYF">Stuxnet worm</a> demonstrated the vulnerability of these systems to cyber incidents. The United States and other governments have passed <a href="/facts/Cyber-security_regulation/8e7WYbXd">cyber-security regulations</a> requiring enhanced protection for control systems operating critical infrastructure. </p><p>Control system security is known by several other names such as <i><a href="/facts/SCADA/nKL6Mfd1">SCADA</a> security</i>, <i>PCN security</i>, <i>Industrial <a href="/facts/Network_security/09f8YxwD">network security</a></i>, <i><a href="/facts/Industrial_control_system/YzgsMy2x">Industrial control system</a> (ICS) Cybersecurity</i>, <i><a href="/facts/Operational_Technology/jHUvzTEl">Operational Technology</a> (OT) Security, Industrial automation and control systems</i> and <i>Control System Cyber Security</i>. </p>
