Social media comprises online services where people and organizations publish content, communicate, and form networks. The term covers public posts, private messages, groups, live streams, advertising systems, and the APIs and third-party applications that process platform data.
For security teams, these platforms expose identity, relationship, and behavioral information that can support targeted phishing, impersonation, or social engineering. Compromised accounts may be used to distribute malicious links or fraud, while excessive sharing and poorly controlled integrations can expose personal or corporate data. Relevant controls include strong authentication, phishing-resistant account recovery, least-privilege access for connected applications, monitoring for brand and executive impersonation, and clear retention and privacy policies. Public posts and platform telemetry can also provide threat intelligence, but collection and use may be constrained by privacy obligations and applicable data-protection rules.
