Graph database security is critical for protecting sensitive data from unauthorized access, breaches, and cyber-attacks, which is why Memgraph incorporates essential security features such as authentication, authorization, encryption, and auditing. Authentication in Memgraph ensures that only authorized users can access the database by verifying their identity through various methods, including 2FA and biometrics, while authorization manages data access and modifications using role-based access control and the least privilege principles. Encryption secures data both at rest and in transit, ensuring it remains unreadable without the correct decryption key, and Memgraph supports encryption during transit through TLS and HTTPS, though at-rest encryption can be configured with tools like LUKS. Auditing in Memgraph tracks database activities by logging executed queries, which helps in detecting suspicious activities and ensuring compliance. These features collectively enhance data security and integrity, supporting business operations and decision-making by preventing downtime and safeguarding critical information assets.
