EOL Asset DB – Certificate management

The IT Assets Database was replaced by the IT Admins CMDB and is EOL / End of Life, no further development will be done on this project.

Certificates have a major impact on the security and stability of any modern IT environment. It is essential to document where they are in use and to know when they expire. The certificate module allows you to relate them to various serves and web servers as well as relate them to an expense (assuming they had been bought from a public CA). You can add additional notes and TAGs to them and easily document the whole picture while documenting the most essential and basic information.

This helps a lot – especially while they often are valid for two to three years and the exchange with a new certificate later proofs a hassle simply because you don’t even know where exactly a certain certificate was used at – like a DMZ based web server, the firewall and an internal web-sever – it is easy to forget one of the places and due to the long time in between a specific certificate needs to be exchanged, it is hard to remember it all. Might be even you exchange a server that did hold a certificate – you might just forget it was there – or you had an expense set up to renew it but the servers that used it already have been retired.
