The importance of security should never be underestimated. The consequences of losing data can be disastrous for any organisation. For example, the loss of a single unencrypted laptop may have huge repercussions. This could include breaching data protection legislation with the risk of a significant fine, a loss in the confidence of an organisation, as well as the risk that sensitive data may fall into the hands of a competitor or third party with malicious intent.
Disk encryption uses disk encryption software to encrypt the entire hard disk. The onus is therefore not on the user to determine what data should be encrypted, or to remember to manually encrypt files. By encrypting the entire disk, temporary files, which may reveal important confidential data, are also protected. Security is enhanced further when disk encryption is combined with filesystem-level encryption.
To provide an insight into the open source software that is available, we have compiled a list of 5 notable disk encryption tools. Hopefully, there will be something of interest here for anyone who wants easy-to-use data encryption and security.
