What Role Does Encryption Play in Data Security?

Blog Posts

Online Tech’s Senior Product Architect Steve Aiello continues his data security series of videos on data encryption by explaining how encryption fits into the three premises of security.

Encryption plays into the three premises of security:

  1. Confidentiality – keeping data private
  2. Integrity – the accuracy of your data
  3. Availability – keeping your web server online and data available

Encryption helps with mainly the premise of confidentiality – keeping prying eyes off of confidential data.

Aiello explains how the balance of all three premises may be difficult to balance while keeping data confidential.

Identifying critical data, such as protected health information (PHI) for the healthcare industry and credit cardholder data (CHD) for the ecommerce and retail industry, is the first step toward determining what data needs to be encrypted and confidential.

The increased cyber threats of hackers and data theft presents a strong case for employing encryption and infrastructure that both secures data while delivering strong computing performance for optimal data availability and reliability. In this white paper, different types of encryption will be discussed, including using encryption in the cloud.

Although encryption is not a silver bullet of data or system security, it is one key tool that can be accompanied by a full arsenal of security services for a layered-defense approach to ensuring data is protected, even if accessed by unauthorized individuals. Additional security options to add to your IT solution will be covered.
