Security Posture

Definition ∞ A security posture describes the overall state of an organization’s cybersecurity defenses and its readiness to counter threats. It represents the collective measures, policies, and practices in place to protect digital assets and systems. A strong security posture is characterized by proactive threat detection, rapid incident response capabilities, and continuous risk assessment. It is a dynamic measure, requiring constant evaluation and adaptation.
Context ∞ The security posture of entities operating within the cryptocurrency and blockchain space is under intense scrutiny, particularly given the increasing frequency of sophisticated cyberattacks. News cycles often report on security audits, vulnerability disclosures, and the implementation of advanced threat mitigation strategies by exchanges, custodians, and protocol developers. The focus is on establishing resilient defenses that can withstand persistent and evolving adversarial tactics.
