, DEEL 1: CYBERSECURITY FUNDAMENTEN

1.1 CIA-Triad en Principes

CIA-Triad = KERN van informatiebeveiliging!


Confidentiality (vertrouwelijkheid):
→ Alleen BEVOEGDEN zien data!
→ Maatregelen: encryptie, toegangscontrole, classificatie!
→ Classificatie: openbaar → intern → vertrouwelijk → geheim!


Integrity (integriteit):
→ Data is CORRECT + COMPLEET + ONGEWIJZIGD!
→ Maatregelen: hashing, digitale handtekeningen, versioning!
→ Hash: SHA-256 → unieke vingerafdruk van data!


Availability (beschikbaarheid):
→ Systemen zijn BESCHIKBAAR wanneer nodig!
→ Maatregelen: redundantie, backup, load balancing, DDoS-bescherming!
→ Uptime: 99,9% = 8,7 uur downtime/jaar. 99,99% = 52 min/jaar!


Aanvullende principes:
→ Authentication: WIE ben je? (bewijs je identiteit!)
→ Authorization: WAT mag je? (rechten/rollen!)
→ Accountability: WIE deed WAT? (logging, audit trail!)
→ Non-repudiation: je kunt niet ONTKENNEN (digitale handtekening!)


→ Least privilege: alleen de rechten die je NODIG hebt!
→ Need-to-know: alleen info die RELEVANT is voor jouw functie!
→ Defense in depth: MEERDERE lagen beveiliging (als 1 faalt!)
→ Zero Trust: "Never trust, always verify" (niet automatisch vertrouwen!)
→ Verificatie bij ELKE toegang (ook intern netwerk!)
