FAQs
While encrypting all data sounds appealing, in practice it is more complex. Organizations should conduct risk assessments and classify data to define which data truly requires encryption based on sensitivity and protection needs. Blanket encryption of all data can introduce unnecessary costs, complexity, and usability issues if not managed carefully.
Some hackers do target encrypted data in hopes of cracking or circumventing the encryption through brute force attacks or by exploiting flaws in algorithms or implementations. Strong encryption with sufficient key length makes this mathematically infeasible. And best practices like key rotation and revocation limit the window of exposure. Encryption may not stop the most determined attackers but significantly raises the difficulty bar.
Encryption does introduce additional complexity, which means more opportunity for risk if not managed properly. Processing overhead may impact performance and efficiency. Encrypting and managing large volumes of data can be challenging. There is also the possibility of losing access to encrypted data if keys are lost. Organizations should weigh upsides vs downsides based on their specific needs and risk profile.
This is one of the risks of encryption: The permanent loss of access to encrypted data without the keys. Organizations should have documented procedures for secure key generation, storage, rotation, and recovery. Forgetting keys means irrevocable data loss, so key management is critical.
It is important to validate encryption is implemented effectively before reliance in production. Best practices include design reviews, proof of concept testing, simulated attacks, audit logging, key/user lifecycle processes, and interoperability assessments. Performing both technical security tests as well as usability tests helps confirm encryption works as intended.
