What is database security? – Definition from Techopedia

What does database security mean?

Database security refers to the collective measures used to protect and secure a database or database management software against illegitimate use and malicious cyber threats and attacks.

Database security procedures aim to protect not only the data inside the database, but also the database management system and all applications that access it from intrusion, misuse of data and damages.

It is a broad term that includes a host of processes, tools, and methodologies that provide security in a database environment.

Techopedia Explains Database Security

Database security covers and enforces security on all aspects and components of databases. This includes:

Database security is typically planned, implemented, and maintained by a database administrator and/or other information security professional.

Here are some of the ways database security is analyzed and implemented:

  • Restrict unauthorized access and use by implementing strong, multi-factor data management and access controls.

  • Load/stress testing and capacity testing of a database to ensure it does not crash during a Distributed Denial of Service (DDoS) attack or user overload.

  • Physical security of the database server and backup equipment against theft and natural disasters. Regular data backups can be scheduled as part of a database security protocol, and multiple copies can be stored offsite to provide redundancy and disaster recovery.

  • Review the existing system for any known or unknown vulnerabilities and define and implement a roadmap/plan to mitigate them.

  • Data encryption can provide an additional layer of security to protect data integrity and confidentiality.

Applying proper database security practices is vital for any organization for a variety of reasons. These include:

  • Ensuring business continuity: Many businesses cannot operate until the breach is resolved.

  • Minimize financial damage: Once a breach occurs, an organization must incur significant financial costs to communicate the breach to all of its customers, manage the crisis, repair or update affected systems and equipment, pay for investigation activities, etc. .

  • Loss of intellectual property: If a database is accessed, it is possible that a company’s trade secrets, proprietary procedures, and other forms of intellectual property could be stolen or exposed. In some cases, this means the complete loss of any competitive advantage maintained by that organization.

  • Damage to brand reputation: Once a breach is notified to customers, partners and customers can lose confidence in the organization’s ability to protect their data. The reputation of the brand will suffer and many may decide to no longer buy the products or services of this organization.

  • Penalties and fines: Organizations must comply with a large number of regulations, such as the General Data Protection Regulation (GDPR), Payment Card Industry Data Security Standard (PCI DSS), HIPAA (Health Insurance Portability and Accountability Act), etc. If a data breach occurs because the organization failed to comply with these regulations, the fines and penalties can be very severe, in some cases even exceeding several million dollars per breach.
