Data at rest protection

There a few ways to prevent a loss or theft of data that is stored.

  1. Theft of the data can be prevented by implementing encryption of the data. Even if an intruder is able to access the data, it will not make sense.
  2. Backup solution means that a version of data is available in the backup. It is important to have proper data included in the backup, test the backups and store backup in a secure offsite location, since data in backups maybe sensitive. Backups need to be tested regularly to ensure that they work.
  3. Redundancy at hardware level means that multiple copies of data is made and it is located on more than one server.
  4. Snapshots allow a user to go back to a version of a file that was available on certain day.
  5. It is possible to implement redundancy of the data for real-time access to it. It can be done by having data stored in multiple servers (ideally locations) or disks.

If not a trusted person get an access to this information, this information maybe used against the company and for a personal benefit. What to do in a case when there are more servers than one? Even so it is possible to inspect the log files in a single server, however it is impossible to do so when there is more than one server is available and web traffic is redirected to a different server each time. Log aggregation is needed in this case. All of the logs will be send to a central location. Logs may contain sensitive information. Please consult your company lawyer of how long logs can be stored, because logs can be use...

goto PHP operator

goto operator will skip execution of code and continue execution of a code that follows a label to which goto operator points to. If code has many goto operators, than this code probably needs a revision. It is possible to write code that executes without goto operators.
