What is the focus of operational security in information security?

Operational security in information security primarily focuses on the implementation and maintenance of controls that ensure both the confidentiality, integrity, and availability of information systems. This includes critical IT security controls such as malware protection, which safeguards against unauthorized software that can compromise data, and backups, which are essential for data recovery in the event of loss or failure.

By addressing these operational security measures, an organization can mitigate risks from potential threats and vulnerabilities effectively. It ensures the security of information systems and data in everyday operations, responding to ongoing and evolving security challenges.

While physical access controls, management of external vendor relationships, and development of asset management policies are important aspects of an overall information security framework, they do not encapsulate the primary focus of operational security, which is centered around protecting systems and data through active security measures and controls.
