Security vs. Privacy: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on October 26, 2023
Security relates to protection from harm, while privacy concerns the right to keep personal information concealed.

Key Differences

Security is the process or measure taken to guard against threats, damages, loss, or any form of unauthorized interference. Privacy, on the other hand, relates to the state of being free from public attention or the unauthorized disclosure of one's personal data.
Security often refers to measures that protect individuals, organizations, or nations from threats like crime, terrorism, or espionage. Privacy revolves around ensuring that personal data, communications, or activities are not exposed or accessed without permission.
From a technological standpoint, security can be seen in protocols, firewalls, and encryption that safeguard data from hackers. Privacy in this context pertains to controlling who has access to personal data and how that data is used and shared.
Security is sometimes sacrificed to enhance privacy. For instance, anonymizing tools might reduce some security features to increase user anonymity.
Security and privacy are deeply interconnected. Strong security measures help maintain privacy, and ensuring privacy can often require robust security mechanisms.
