Unauthorized Data Access

Summary

Unauthorized Data Access is a type of application attack where an attacker gains access to sensitive or confidential data without proper authorization, often exploiting vulnerabilities in software, misconfigurations, or weak authentication mechanisms.

Key Characteristics

• Exploitation of application vulnerabilities such as SQL injection, broken access controls, or insecure APIs.
• Bypassing authentication or authorization controls to retrieve data.
• Access to sensitive information including personal data, financial records, or intellectual property.
• Often involves privilege escalation or lateral movement within systems.
• May be performed by external attackers or malicious insiders.

Defensive Controls

• Implement strong authentication and authorization mechanisms, including multi-factor authentication.
• Conduct regular security assessments and penetration testing to identify vulnerabilities.
• Enforce least privilege access policies and role-based access control (RBAC).
• Use input validation and parameterized queries to prevent injection attacks.
• Monitor and audit access logs to detect unauthorized activities.
• Apply timely patches and updates to applications and underlying systems.
