Databases are often the targets of security attacks by cyber criminals. Databases that hold all the security related information, passwords and financial details of users are what these attackers are looking to profit off. That is why database security is an incredibly complex topic that can be covered in elaborate detail. Get in touch with your remote DBA now.
However here are a few of the best practices in database security that will help businesses.
1. Keep the database and the web servers separate.
Usually when the entire web related software is been installed, the database is automatically made. For the sake of convenience the database is made on the same server where the software has been loaded which is the web server. However this opens the doors for a security breach because then hackers will only need a single point of entry. If they are able to make their way past the security for the web server then all the data stored will be at their mercy.
This is why the database should be stored separately on server that is further protected by a firewall and not with the web server. It is a more intricate but well needed procedure. To know more visit - http://www.remotedba.com/
2. File encryption
Just storing the database on a separate server is not enough to ward off persistent attacks. Encrypt all the files that are being stored. The stored files of the web software have the information that will enable it to connect to the databases. If you store the data in plain text files like a lot of people then they will provide the data that the hacker needs to get to the sensitive information.
It is not just the files that need to be encrypted. Encrypt the backup files too incase there is an internal attack.
3. WAF
Use WAFs or web application firewalls. It isn’t true that the web server protection is completely separate or irrelevant to the database. A proper WAF will protect your website from cross site script vulnerabilities, vandalism and also potential SQL injection attacks. If SQL queries can be prevented from being injected by a criminal then the firewall will be successful in keeping all the sensitive information which is stored in a database away from unwanted attention and attacks.
4. Current patches
This is one thing that a lot of web administrators like remote DBA fall short. Web sites which have a lot of third party apps, elements, widgets, plug-ins and other add-ones become easy targets to something that could have been patched on time.
5. Less third party apps
Try and reduce the number of third party applications being used. While it is understandable to use user-interactive widgets and other content that makes websites attractive, any app that accesses the database is always a weak point which can be exploited. Unless it is required don’t use third party apps. Remember that these are made by programmers who then stop support after a while.
6. No shared servers
If your database has highly sensitive information then don’t use a shared server if you can avoid it. It will be cheaper and easier. However remember that you are putting all your important data at the hands of someone else. In case you can’t avoid it, do a keen review of all their security protocol.
7. Security controls
Put in security controls on your database. Check your controls and ensure that they have been enabled even though it is automatically enabled by most databases these days.
