Security posture refers to the overall status and strength of an organisation's security measures, policies, procedures and capabilities in relation to its threat environment. It encompasses the effectiveness of technical controls, the maturity of governance processes, the awareness level of staff and the ability to detect and respond to incidents. A strong security posture indicates comprehensive, well-maintained defences.
Assessing security posture is an ongoing activity that involves vulnerability scanning, penetration testing, compliance audits and risk assessments. Organisations use security posture evaluations to identify gaps, prioritise investments and demonstrate due diligence to regulators, customers and partners. Continuous improvement of security posture is a core objective of any ISMS.
