First, contain immediately - revoke access privileges without alerting them. Simultaneously preserve evidence by capturing logs and documenting their activity patterns. Then investigate with precision - understand what was shared, to whom, and potential exposure scope. This isn't just about one person - examine whether this reveals systemic security culture issues. Address the individual through HR following established protocols, but focus equally on root causes. Was this malicious or ignorance? Did they bypass controls that need strengthening? Turn this incident into organizational immunity by reinforcing training, implementing technical safeguards where gaps exist, and creating psychological safety for reporting concerns.

Use Microsoft Purview Audit to track what was shared and identify exposure, then enforce Microsoft Purview Data Loss Prevention (DLP) policies to automatically block sensitive data sharing across emails, endpoints, and cloud apps. Strengthen access with Microsoft Entra Conditional Access and Access Reviews to prevent unauthorized access. Integrate Microsoft Defender for Cloud Apps with DLP to monitor and restrict sensitive data movement in cloud environments. Use Microsoft Defender XDR to detect insider risks in real time. Reinforce security awareness, leverage Microsoft Learn for resources, ensuring employees understand the risks and consequences of mishandling sensitive data.

Based on ISO/IEC 27001: 1. Contain the Breach Revoke access & preserve evidence (Clause 9.2, 7.5). 2. Inform Authorities Investigate & involve legal if needed (Clause 7.2, 5.1). 3. Interview the Employee Determine motive & follow procedures (Clause 7.2, 9.1). 4. Implement Security Measures Tighten access controls, DLP, & encryption (Clause 9.1, 8.3, 10.1). 5. Update Policies Enhance training, NDAs, & response plans (Clause 7.2, 8.1, 6.1). 6. Communicate Notify affected parties (Clause 5.3). 7. Legal Action Consult legal if necessary (Clause 9.1). 8. Preventive Measures Strengthen detection, audits, & culture (Clause 9.1, 9.2, 5.1).

When confidential information is exposed, we act quickly to contain risks and avoid impacts: Contain and Investigate – We block unauthorized access and analyze the incident. Notify and Correct – We inform leaders and apply disciplinary measures as necessary. Prevent New Cases – We reinforce controls and training to prevent recurrences. We ensure an agile, transparent response that is aligned with corporate guidelines.

PRIVACY VIOLATION - When anyone shares confidential information carelessly, it must be thoroughly researched & quickly resolved. As a starting point the SECURITY INCIDENT RESPONSE PLAN provides well thought out written guidance in advance. Bypassing security is serious & must be investigated: * RCAs & WHO/WHY/WHERE/WHEN for these violations? * Was violation intentional? accidental? job related? * Do security POLICIES need to be improved? * Do policies need better communications? * IMPACT analysis for HUMAN side of failure? * For highly sensitive INFO, contact all participants & stress confidentially * For major intentional acts, disciplinary actions outside security may be needed * Target & conduct needed security awareness training

Más allá de reforzar accesos y monitorear actividades, es importante fomentar una mentalidad de seguridad dentro del equipo. Crear simulaciones de phishing, establecer canales de denuncia anónimos y reconocer buenas prácticas puede prevenir futuras filtraciones.

Whenever an organisation finds that it's sensitive information is compromised by its employee the immediate action must be taken to Identify the breach, revoke unauthorized access, and analyze intent (accidental or malicious). Strengthen access controls, reinforce data handling policies, and implement DLP solutions, so that such type of incidents are prevented in future. Conduct security awareness training and enhance SIEM & logging for proactive detection. If the information is shared intentionally then it must be Escalate to HR/legal teams, ensuring compliance with company policies.

So verhindere ich weitere Sicherheitsverletzungen durch einen Mitarbeiter: - Zugriff sperren: Sofort alle Berechtigungen des Mitarbeiters widerrufen. - Untersuchung einleiten: Umfang und Ursache des Verstoßes klären. - Zugriffskontrollen überprüfen: Nur notwendige Berechtigungen vergeben. - Sicherheitsrichtlinien schulen: Team über Datenschutz und Konsequenzen informieren. - Meldesystem etablieren: Klare Kanäle für interne Vorfälle schaffen. - Rechtliche Schritte prüfen: Den Vorfall juristisch bewerten und gegebenenfalls Maßnahmen ergreifen.

Se você descobriu que um funcionário compartilhou informações confidenciais de segurança, é crucial agir rapidamente para conter a violação e evitar que ela se repita. Lembre-se de que a prevenção é a chave para evitar violações de segurança. Ao implementar políticas e procedimentos robustos, fornecer treinamento adequado e monitorar continuamente os sistemas, você pode reduzir o risco de futuras violações.
