Cyberspace and its underlying infrastructure are vulnerable to a wide range of risk stemming from both physical and cyber threats and hazards. Sophisticated cyber actors and nation-states exploit vulnerabilities to steal information and money and are developing capabilities to disrupt, destroy, or threaten the delivery of essential services. As Americans become more reliant on modern technology, we also become more vulnerable to cyberattacks such as corporate security breaches, spear phishing, and social media fraud. Law enforcement performs an essential role in achieving our nation’s cybersecurity objectives by investigating a wide range of cyber crimes, from theft and fraud to child exploitation, and apprehending and prosecuting those responsible. The Department of Homeland Security (DHS) works with other federal agencies to conduct high-impact criminal investigations to disrupt and defeat cyber criminals, prioritize the recruitment and training of technical experts, develop standardized methods, and broadly share cyber response best practices and tools.
Cybersecurity and Computer Science
Criminal investigators and network security experts with deep understanding of the technologies malicious actors are using and the specific vulnerabilities they are targeting work to effectively respond to and investigate cyber incidents. The mission of DHS’s Network Security Deployment (NSD) division is to improve cybersecurity to federal departments, agencies, and partners by developing the technologies and establishing the services needed to fulfill CS&C’s cybersecurity mission. NCPS is an integrated system-of-systems that delivers a range of capabilities, including intrusion detection, analytics, intrusion prevention, and information sharing. These capabilities provide a technological foundation that enables DHS to secure and defend the federal civilian government’s information technology infrastructure against advanced cyber threats.One of DHS’s key technologies within the NCPS is EINSTEIN. EINSTEIN allows DHS to both detect cyber attacks targeting federal civilian government networks and actively prevent potential compromises. The EINSTEIN program also serves as a platform to aggregate federal civilian executive branch traffic so that DHS can implement new and advanced protections. In other words, by putting all federal government traffic through a few locations, DHS can easily add security tools to those locations.
