Securing networks is a preventative measure in the fight against cybercrime and attacks. The federal enterprise depends on information technology (IT) systems and computer networks for essential operations. Keeping networks safe protects the vital information and operational processes that live and depend on these systems. Networks face large and diverse cyber threats that range from unsophisticated hackers to technically competent intruders using state-of-the-art intrusion techniques. Many malicious attacks are designed to steal information and disrupt, deny access to, degrade, or destroy critical information systems. Securing a network involves continuous monitoring, assessments, and mitigation across various interrelated components, including servers, the cloud, Internet of Things (IoT), internet connections and the many physical assets used to access networks.
CISA works with each federal civilian department and agency to promote the adoption of common policies and best practices that are risk-based and able to effectively respond to the pace of ever-changing threats. When networks are protected, alerts can be issued at machine speed to help protect related or similar networks across the government information technology enterprise and the private sector. CISA provides the coordinating efforts and broad reach needed to create an enterprise approach to securing networks. This enterprise approach transforms the way federal agencies and private sectors manage cyber networks through strategically sourced tools and services that enhance the speed and cost effectiveness of federal cybersecurity procurements and allow consistent application of best practices.
