Mitigating Database Security Threats

Hackers keep on unleashing attacks intended to steal confidential data, and database servers are often the primary targets of these attacks posing a serious security threat to the targets. The reason databases are under attack so frequently is pretty simple—they are the center of every organization, storing customer records and other private business information.

The chances of a breach security threat rise when the organization lacks behind to enforce training and develop a work culture that ensures security consciousness. Organizations are not able to protect their vital resources well enough.

Database Security Threats

It is considered necessary to use a combination of finest techniques and internal control to mitigate database security threats. The possible measures are:

  • Inference Control: It is used as a control measure for Statistical database security threats. A statistical database is a database which contains precise information on individuals or events but is proposed to allow only statistical queries. However, it is possible to get private data on individuals employing only statistical query.  By using inference control technique, we can forbid sequence of queries that generate repetitively.

  • Flow Control: It regulates the distribution of information among accessible objects. It checks that data enclosed in some objects does not flow explicitly or implicitly into a lesser amount of restricted objects.
  • Encryption: The main idea behind encryption is to assign an encryption algorithm to the data. It uses a user-specified key. The data gets converted into an encrypted version. Then there is also a decryption algorithm which turns encoded data into its original form using a decryption key.

  • Monitoring Database Access Activities: Database of an organization comprises of crucial information and is used by several users.  Almost users access only a small part of the database. It is undesirable to allow unlimited access to all the data. The database should provide mechanisms to control access to data.

  • Training Employees: Employees should get training to recognize frequent cyber threats like- spear-phishing attack;  learn   about best practices for Internet and e-mail use and password management.
