Common Database Security Issues

In simple words database security means measures adopt to secure database. Database usually holds the sensitive and crucial information of any business, so that’s why it is necessary to protect it from attackers. The main purpose of database security is to cover the data record from misuse by hackers. Database security assures the database security against internet threats. It is concerned with data protection, database system protection, stored functions protection, database server and the associated network links protection. Security should be assured in its operating system, its database and on network. Below there are certain issues regarding database security.

Daily Maintenance:

 

Database audit require daily review to make sure that there is no misuse of use. This requires manage database privileges and then consistently updating users access accounts. A database security manager also provides different kinds of access control for different users and assesses new programs. If these tasks are performed on a daily basis, you cannot have to face security issues much with the users that may affect the security of the database. 

Manage User Passwords:

Sometimes there may be blank password, weak password database security managers forget to remove IDs of such users and access privileges of former users which lead to password vulnerabilities in the database. Password rules and maintenance needs to be strictly applied to avoid opening up the database to unauthorized users, so that misusing of data can be avoided.

Post-Upgrade Evaluation:

When a database is upgraded it is necessary for the administrator to perform a post-upgrade evaluation to make sure that security is consistent across all programs. If fail to perform this action opens up the database to attack.

Excessive stored procedures:

25 per cent of databases were found to have an excessive number of dangerous stored procedures. This issue is considered to present a risk to the security process of database. Stored procedures effectively increase the functionality which could be the reason of attacks against the operating system of the host.

SSL not enabled:

Databases accepted connections if an attacker has access to the network and is able to sniff the network traffic then the privacy and integrity of this transmission could be affected.

Default Account Name:

Databases were found to contain default accounts. It is always recommended that that default accounts are locked and renamed where possible as they can be used as the target of password guessing attackers.

Windows OS Flaws:

 

Windows operating systems are not effective when talk about database security. Even passwords can be easily hacked. The database security manager should take measures through daily maintenance checks. 

Application Spoofing:

 

Hackers are capable of creating applications that is similar with the existing applications connected to the database. These applications are often difficult to identify and allow hackers to approach the database via the application in disguise.
