Security Manager discussion group

 S2_Online is an email list server for qualified security managers to help other new security managers. This is shared brain power where we can ask for assistance and leverage the the combined experience of experienced Security Managers - Click here for the S2_Online Email List Server (Formerly Security Managers Info List Server)


S2's are the Intelligence and Security Officer for Military Units. This is often a thankless job, where they receive little training.


Doctrinally, OPSEC does not belong to the G2 or S2, it belongs to the G3 or S3.  I always say, if we had named OPSEC, it would be SECOPS...with Security First.  Humor goes along way when explain doctrine to the S3.


OPSEC is also about security education. Security education is something the G2 and S2 community does not do well. When you read the Safety Holiday Message, signed by your commander, ask yourself... Is safety more important than Security or OPSEC?  Where is that message?  Has the 2 community failed to get the commander to push info to the potential security or OPSEC violators?

Below is an article I wrote titled: Commentary: OPSEC-60 Years and Counting, Remembering the Korean Conflict.  My PAO picked it up and sent it to the Army Publishing Service.


Without a doubt IOSS is the premier place to look for OPSEC information.  Below is some of the info from their website.

About the IOSS

Who We Are

In 1988, President Ronald Reagan signed National Security Decision Directive 298 (NSDD 298). This directive established the National Operations Security Program as a means to identify, control, and protect unclassified information and evidence associated with U.S. national security programs and activities. Adversaries or competitors working against the interests of the United States can exploit this information if it is not properly protected.

The NSDD 298 named the Director, National Security Agency, as the Executive Agent for interagency OPSEC training and included in his responsibilites the estabishment and maintenance of the Interagency OPSEC Support Staff. By mandate, this organization shall include representatives from the Federal Bureau of Investigation, Central Intelligence Agency, Department of Engery, Department of Homeland Security, and Department of Defense, including the National Security Agency. Other government agencies are encouraged to provide personnel to this staff and participate in interagency OPSEC forums.

The primary responsibility of the Interagency OPSEC Support Staff (IOSS) is to act as a consultant to other U.S government departments or agencies by providing technical guidance and assistance that will result in self-sufficient OPSEC programs for the protection of the U.S. operations. Members of the IOSS staff assess OPSEC programs, assist in OPSEC program development, conduct surveys, and provide training.

The IOSS further supports the National OPSEC Program by providing multimedia products and presenting events that attract attendees from the security, intelligence, research and development, acquisition, and law enforcement communities. These events include the National OPSEC Conference and Exhibition, the National Threat Symposium, and regional training symposia.
