Operational security is the process of identifying, protecting, and controlling sensitive information and
activities from unauthorized access or disclosure. Operational security includes background screenings for
personnel who need to access classified or restricted information or resources, as well as implementing
policies and procedures to prevent leaks, breaches, or espionage. Operational security is essential for
government projects that involve national security, defense, intelligence, or law enforcement.
Operational security is different from data security, which is the process of safeguarding data from
unauthorized access, use, modification, or destruction. Data security includes encryption, authentication,
authorization, backup, and recovery of data. Operational security is also different from physical security,
which is the process of securing physical assets, such as equipment, data, or personnel, from unauthorized
access or damage. Physical security includes locks, alarms, cameras, guards, and fences. Operational security
is also different from digital security, which is the process of protecting digital devices, networks, and systems
from cyberattacks, malware, or hacking. Digital security includes firewalls, antivirus, VPN, and passwords.
