Data Breaches

Summary

Data breaches occur when unauthorized individuals gain access to sensitive, confidential, or protected information from an organization’s systems or applications. These breaches often result from exploiting vulnerabilities in applications, weak security controls, or insider threats, leading to data theft, exposure, or misuse.

Key Characteristics

• Unauthorized access to sensitive data such as personal information, financial records, or intellectual property
• Exploitation of application vulnerabilities including SQL injection, insecure APIs, or misconfigurations
• Often involves large-scale data exfiltration impacting numerous users or systems
• May result from phishing, credential theft, or insider threats
• Can cause reputational damage, regulatory penalties, and financial losses

Defensive Controls

• Implement strong access controls and multi-factor authentication
• Regularly patch and update applications to fix vulnerabilities
• Conduct thorough security testing including penetration testing and code reviews
• Encrypt sensitive data both at rest and in transit
• Monitor and analyze logs for unusual access patterns or data exfiltration attempts
• Educate employees on phishing and social engineering risks
