Learn the basics of Database Security

Though some attackers still concentrate on denial of service attacks and destruction, cyber criminals frequently target the database because that is where the wealth is. The databases sites hold a huge deal of valuable data for someone looking to steal credit card information or personal details.

Database security itself is an enormously profound subject that may perhaps never be covered in the course of one article, but there are only some best practices that can assist even the smallest of organizations protect their database enough to make an attacker shift on to an easier target.

  1. Separate the Database and Web Servers- Database server should be kept separate from the web server. A database must exist on a separate database server placed behind a firewall, not in the DMZ with the web server. Though this makes for a more complex set of connections, the security benefits are well worth the shot.
  2. Encrypt the Stored Files- Almost websites are susceptible to as a minimum one type of attack. The stored files of a web application often hold data about the databases the software requires for connection. If this data is stored in plain text like several default setups, provide the keys an attacker needs to obtain sensitive information.
  3. Encrypt Your Backups Too- It is not necessary that an attacker will also be someone from an external environment. At times, it is possible that the most trusted can also indulge in attacks.
  4. Use a WAF- Make use of the web application firewalls. It is a misconception that protecting the web server is not related to the database. Besides protecting a site from the cross-site scripting exposures and web site destruction, a high-quality application firewall can also prevent SQL injection attacks too.
  5. Keep the Patches up to date- This is one part where administrators often turn up short. Web sites that are loaded with third-party applications, widgets, components and a range of other plug-ins and add-ons can easily get themselves a target to an exploit that must have been patched.
  6. Don’t Use a Shared Server- If your database contains sensitive data, then you must avoid using a shared web server. Though it could be easier, and economical, to host your site with a hosting source, you are in effect handing over the security of your data to someone else. If you don’t have another alternative, then must evaluate their security policies and have a word with them about their responsibilities in case of any security breach.
  7. Enable the Security Controls- These days the majority of databases facilitate the security controls by default, but you must go through and make sure to verify if it was done or not.
