How To Carry out a Database Security Audit

A database security audit is the act of monitoring a company's database to watch the actions of the users that are able to access the database. This is done as a security measure so that all the vital information in the database is not tampered with by the ones who are granted access to the database and to make sure that no unauthorized person will be able to get into the database. There are different ways to perform database security auditing.

Here are some ways on how a database auditing is carried out:

  1. Server Security - This is the act of limiting the users who can access the database server. This is done so that no unauthorized person is capable of accessing vital information in the database. What is done here is that the server of a company only grants access to computers that have a trusted Internet Protocol address. Also, the database's server is configured to admit only connections from that certain web server. This will make sure that no outside people can access the database.
  2. Database Connections - System administrators do not allow unauthorized updates to be done on the database. Any update that will happen should be screened so that it is sure to be a legitimate and safe update. There are people in the company who have access to the database as system administrators. They could use this privilege to tamper with the database and access vital information. The system administrator should monitor anyone who has access to the database as a system administrator to make sure that he is not violating security measures.
  3. Table Access Control - This is considered one of the hardest database security audits to be applied on the database. This is because the developer of the database and the system administrator will have to collaborate to make this effective. If this is implemented on the database, what happens is that there will be a checklist of all the systems that have access to the database. The access control list will then be able to identify which user is capable or accessing the system or the database. This is a great way to closely monitor the activities of those who have access to the database.
  4. Restricting Database Access - This is a security measure for databases that are hosted on the Internet. The server is only able to let a system access the database from a list that contains all the trusted hosts. Users are only allowed up to three password attempts. If a user fails to provide the correct password after three attempts, the user's account will be disabled and access privileges will be taken away. There can also be a software or a web application security used to alert the system administrator when someone using an unknown server is attempting to gain access to the database.

These are the four ways that a security audit for a database is carried out. This is to make sure that no unauthorized person has access to sensitive data that can be used for malicious purposes.
