Implement data security concepts, governance, authentication, infrastructure security, and threat mitigation strategies (23% of exam).
Covers applying encryption (in transit, at rest), data masking, and destruction techniques for data security. Includes implementing data loss prevention, retention policies, and regulations like GDPR and PCI DSS for governance and compliance. Encompasses managing access controls, password policies, and identity management for authentication and authorization. Also covers physical controls like biometrics and fire suppression, logical controls like firewalls and port security, and threat mitigation for SQL injection, denial of service (DoS), phishing, ransomware, and brute-force attacks.

In the context of CompTIA DataSys+, data and database security are foundational domains focused on protecting information assets from unauthorized access, corruption, and theft. The curriculum emphasizes the implementation of the CIA triad: Confidentiality, Integrity, and Availability.
A primary defense mechanism covered is Access Control. DataSys+ advocates for the Principle of Least Privilege, ensuring that users and applications possess only the permissions strictly necessary for their functions. This is typically managed through Role-Based Access Control (RBAC) to streamline permission management based on job functions.
Encryption is a critical technical control. Candidates are expected to distinguish between protecting data at rest—utilizing methods like Transparent Data Encryption (TDE) or volume-level encryption—and data in transit, which requires TLS/SSL protocols to prevent interception during transfer. Key management lifecycles are also integral to maintaining encryption integrity.
Furthermore, the certification stresses the importance of Authentication and Auditing. Strong authentication methods, such as Multi-Factor Authentication (MFA) and LDAP/Kerberos integration, verify identity before access is granted. Once inside, Database Activity Monitoring (DAM) and granular logging provide the necessary visibility to detect anomalies, investigate breaches, and satisfy compliance requirements (e.g., GDPR, HIPAA, PCI-DSS).
Finally, infrastructure hardening—patching vulnerabilities, disabling default accounts, and sanitizing inputs to prevent SQL injection—rounds out the security strategy, ensuring a resilient database environment.In the context of CompTIA DataSys+, data and database security are foundational domains focused on protecting information assets from unauthorized access, corruption, and theft.
