The bank failed to implement proper access controls and encryption for customer onboarding APIs, allowing 1.2 million unauthorized accesses to personal data. The incident was compounded by inadequate risk assessment and delayed customer notification, resulting in regulatory penalties. This demonstrates why robust security controls must be maintained especially during system transitions when vulnerabilities are most likely to emerge.","**Immediate actions:**\n- Implement strict authentication and authorization controls for all customer-facing APIs\n- Enable encryption for all personal data in transit and at rest\n- Conduct security assessments before and during system migrations\n\n**Long-term improvements:**\n- Establish API security testing as part of standard deployment procedures\n- Implement real-time monitoring and alerting for unusual API access patterns\n- Create incident response procedures that prioritize customer notification within regulatory timeframes\n\n**Compliance measures:**\n- Develop privacy impact assessments for all system changes involving personal data\n- Train staff on GDPR breach notification requirements and timelines\n- Establish automated breach detection systems with defined escalation procedures",[12,13,14,15,16,17,18,19,20],"CIS Control 3 (Data Protection)","CIS Control 14 (Controlled Access)","NIST SP 800-53 AC-3","NIST SP 800-53 SC-8","GDPR Article 5","GDPR Article 25","GDPR Article 32","GDPR Article 33","GDPR Article 34","published","2026-04-17T14:09:27.003189+00:00","2026-04-17T14:09:26.852+00:00",{"id":7,"url":25,"slug":26,"title":27},"https:\u002F\u002Fgdprhub.eu\u002Findex.php?title=AEPD_(Spain)_-_EXP202406208&diff=51367&oldid=51366","aepd-spain-exp202406208-fd80fe","AEPD (Spain) - EXP202406208",[29,35],{"id":30,"name":31,"slug":32,"description":33,"color":34},"1ec88fde-2d0f-4ed8-932a-33f5ccc0fdc7","Access Control","access-control","Excessive privileges, missing MFA, weak auth","#f97316",{"id":36,"name":37,"slug":38,"description":39,"color":40},"c8b843a5-d5a7-41d1-8d3b-cabded09d2ef","Data Protection","data-protection","Unencrypted data, missing DLP, poor classification","#3b82f6",[]]
