Database Cleanup for Security

Several of my web sites use custom databases. Some of those web sites are gone (on purpose). But the databases were still there.

So I spent a bit of time deleting some unused databases and database users. It’s a security thing: there might be some personal information on some of the databases, and deleting unused data is a ‘good thing’.

Database security is important. Here are a few things to think about:

  • Do you have unused databases anywhere?
  • Is there public/personal information in the data tables?
  • Have you secured the user rights to those databases — not giving full access to a user out of convenience?
  • Do you have backup copies of the databases?
  • Are databases that contain personal information encrypted?

Any other considerations? Let me know in the comments.
