OpSec: Protecting Your Data & Privacy

Operational Security (OPSEC) is a process that helps protect sensitive information from being compromised by unauthorized individuals. It is a systematic process of identifying, controlling, and protecting information that, if revealed, could be used by adversaries to harm an organization or individual. It is a continuous process of assessing threats and establishing countermeasures to protect information and operations. OPSEC includes physical security, personnel security, communications security, information security, and computer security. Physical security includes measures such as locks, fences, guards, and surveillance systems. Personnel security involves background checks, clearances, and security awareness training. Communications security involves encryption, authentication, and secure transmission protocols. Information security involves protecting data from unauthorized access, modification, or destruction. Computer security involves measures such as firewalls, antivirus software, and intrusion detection systems. OPSEC also involves developing and implementing policies and procedures to ensure the security of information, operations, and personnel.
