The Central Intelligence Agency Counterintelligence Center (CIC) protects CIA operations from being compromised by foreign adversaries. To do this, CIC analyzes the capabilities, intentions and activities of foreign intelligence services. CIC officers advise the Director of the Central Intelligence Agency and other Agency components on counterintelligence (CI) and counterespionage objectives, strategies and resources. They also foster CI awareness and expertise among Agency officers and provide advice on operational security.
