Chapter: Data And Database Security
Database infrastructure security is essential to protecting the sensitive data stored in databases, ensuring that the data is kept safe from unauthorized access, corruption, theft, or loss. It involves implementing both physical and logical security measures to safeguard database systems from various threats and vulnerabilities, ensuring confidentiality, integrity, and availability.
1. Physical Security of Database Infrastructure
Overview: Physical security is a critical layer of defense for any database infrastructure. It encompasses a wide range of measures and technologies designed to protect the tangible assets—servers, storage arrays, network equipment, and backup media—that host and support data systems. While logical security can protect against cyber threats, physical security guards against threats such as unauthorized personnel access, equipment tampering, environmental damage, and natural disasters.
