OPSECâs most important characteristic is that it is a process. It is an analytical process that can be applied to any operation or activity for the purpose of denying critical information to an adversary.
Operations security (OPSEC) is a vital component in developing protection mechanisms to safeguard sensitive information and preserve essential secrecy. To develop an effective operations security program, the organization's OPSEC officer must understand the range of threats that confront his activity. This handbook provides unclassified threat information that can be used by OPSEC program managers in developing protection regimes and training organizational personnel.
