The database holds more than rows—it holds secrets. Every query, every login, every SSH session is a potential breach point. Field-level encryption and SSH access proxy harden that surface, locking data at the source and controlling access like a vault.
Field-level encryption encrypts sensitive columns in the database itself, before they leave storage. Even if backups are stolen or a dump is exposed, the fields remain unreadable without the right keys. This is tighter than full-disk encryption; it applies protection exactly where it matters—credit card numbers, personal identifiers, financial records. By keeping encryption at the field level, application logic can define which data is encrypted, how, and when to decrypt. Permissions become cryptographic instead of just role-based.
The SSH access proxy sits between the user and the server. It is a gate. Incoming sessions are terminated at the proxy, checked against policies, then connected to the destination server if authorized. This eliminates the need for direct server keys floating across developer machines. It logs every connection, maps commands to specific identities, and enforces fine-grained restrictions on what each account can do.
When combined, field-level encryption and an SSH access proxy close two critical gaps: exposure through data theft and unauthorized shell access. They form a layered defense—encrypted data is still encrypted when seen over SSH, and SSH sessions themselves are constrained by the proxy. This reduces the blast radius of any security event.
