Description
The ssl-certificate-monitor file is generated by a script or tool that regularly checks SSL/TLS certificates across a list of networked services—such as websites, VPNs, mail servers, and internal apps. Its main job is to verify that the certificates are valid, not expired, properly signed by a trusted CA (Certificate Authority), and correctly chained to a root certificate.
It records the domain or IP being checked, the certificate’s issuer, expiration date, and validation status. Advanced implementations may even test SSL strength (cipher support, key size, protocol version), and alert on weak or deprecated setups.
When expiration is approaching (e.g., within 15 or 30 days), the file can trigger alerts via email, webhook, or internal monitoring system. This prevents downtime or broken secure connections that occur when a certificate expires and clients reject the connection.
This file is especially valuable in environments managing multiple domains or wildcard certificates, where manual tracking isn’t scalable. In security audits, it provides proof of SSL hygiene and proactive certificate management.
