Advanced Persistent Threats
Overview
An advanced persistent threat (APT) works to access computer networks and systems without being detected or noticed. These threats, sometimes enacted by a nation state or state-sponsored group, can steal private information, damage IT systems and disrupt the function of vital systems. Defending against Advanced Persistent Threats is a difficult task as they act stealthily, and their intrusions can be hard to recognize.

CISA offers tools, assessments, and services to enhance network, device, and online safety for both individuals and organizations. CISA coordinates information sharing to spread awareness of vulnerabilities, strategies for defense, and potential threats.
