Intelligence Compromise

Examples of how classified material can be compromised.

  • Classified information in the media
  • Classified documents left in an unsecured area
  • Classified discussions in an unauthorized area
  • Confirming or denying classified information to an uncleared source
  • Transportation of classified material by other than an authorized courier
  • Higher classified material being transmitted on a lower classified system

What to do if there is a compromise.

1. Isolate the information and exposure.

2. Contact the appropriate security official.

1. GENSER compromise contact G-1 Security Branch at 477-8420/8995.

2. SCI compromise contact G-2 Special Security Official (SSO) at 477-8451/8453.

3. SAPs compromise contact Louis Johnson at 477-8915.

4. After hours contact the G-3 Command Operations Center at 477-0077.

3. The security official will take the necessary steps to further notify the proper individuals.

4. If there are questions about a classification call a security official. Do not ignore a compromise. You never know what information, products or lives may be at risk.
