Data encryption is read more an essential component of any security-conscious organization. It transforms plaintext (readable information) into a non-readable code called ciphertext. Only those who have the correct key can decrypt back to its original format. This is also required by regulators in fields like healthcare and financial services.
The importance of encryption is in a mobile environment, where information is constantly transferred between devices and servers. It also keeps anyone from having access to your private information or the secrets of your business, helping you comply with the regulations of compliance and minimize the risk of cybersecurity.
Additionally, encryption can be used to safeguard data stored in fixed locations, like a USB stick or hard drive. This is helpful when the data is taken by unauthorised persons. When combined with other security functions such as authentication, encryption can ensure that even if malware or a malicious insider tries to access the data and tries to read it or use it.
No matter how effective your encryption algorithm, it’s only as good as the security controls that decide who is able to view the encrypted code. This is referred to as security access control or simply access control. Overly focusing on this aspect of security can compromise the confidentiality and integrity of your data by allowing the wrong individuals access to the keys that allow access to it.
