Database security also includes transparency about which users have connected to the database, when and from which address. All cloud databases have logging functions for this purpose. They should be activated directly during the initial configuration, if this has not already happened automatically. The recorded logs are a useful tool for measuring performance and determining the causes of faults, configuration problems and hacker attacks. This records abnormalities in database operation, such as frequently repeated login attempts with changing password entries. The management interfaces of the database systems usually keep the logs for a certain period of time and then delete the oldest ones. However, in order to be able to trace cyber attacks that occurred a long time ago and have not yet been discovered, the log data should also be backed up in other customer-owned systems.
Another tool for dealing australia telegram screening with risks such as cyber attacks, accidental deletion or data center failure is backups. Every cloud database has a corresponding function, which is often activated directly from the factory. It regularly creates a backup copy of the entire database instance with all active tables. In many cases, the procedure is incremental. First, a complete data backup is created, then only the data that has changed on each day is saved. For most providers, these backup copies go back about 90 days, and older ones are deleted. There should be an encryption function for the backups, which should of course definitely be activated.
The providers often back up the data in such a way that only the backup function can access it. Companies should therefore consider introducing an extended strategy: Their goal should be to regularly create complete and encrypted data backups in an additional, customer-owned storage system. Incremental backups are also useful between these times. Companies can decide for themselves how long they are kept. Depending on the load on the database and the business risk of even a small loss of data, it also makes sense to consider a more frequent backup frequency, for example hourly. There are also special cloud services that offer corresponding routines for this.
