Applicationsecurity er praksis med at beskytte software mod trusler — at bygge og vedligeholde apps, så de modstår angreb, beskytter data og opfører sig sikkert. Det betyder noget, fordi sikkerhedsbrud har alvorlige konsekvenser: datatyveri, økonomisk tab og ødelagt tillid.
Hvad applicationsecurity dækker
App security = protecting software and its data from threats throughout the lifecycle:
→ secure CODING (avoid vulnerabilities like injection, XSS)
→ AUTHENTICATION (who are you?) and AUTHORIZATION (what can you do?)
→ protecting DATA (encryption in transit and at rest)
→ input VALIDATION, secure configuration, dependency security, etc.
→ "Security" is a quality of the whole system, not a single feature.
