5 of the Best Free Linux Disk Encryption Tools
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
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.
Of course, whenever information is accessible, there is the
risk of its loss. A misdirected fax or a misdelivered letter can lead
to sensitive information being disclosed in error. But the
severity and ramifications of that risk is exacerbated when the data is
stored on a computer. Modern computer hard disks have the capacity to
store a gargantuan amount of data. A single hard disk may hold personal
details of hundreds of thousands or even millions of individuals. In
event that the data is not encrypted, the loss of the hard
disk may represent an organisation's worst nightmare. The actual cost
of replacing the hard disk of the machine pales into insignificance
compared to the loss of the confidential information and customer
Disk encryption is one method to help minimise the risks by
preventing unauthorised access to data storage, to ensure safe
information exchanges, safeguard against data leakage, and manage
compliance. This form of security is useful for any computer that holds
personal information, not only laptops. 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.
Many organisations and individuals need to encrypt sensitive
files but do not have the funds to buy disk encryption software.
Fortunately, there is a good selection of open source software
available to download at no charge that offers good functionality.
There are many different tools that allow for disk 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.
So, let's explore the 5 disk encryption tools at hand. For
each application we have compiled its own portal page, a full
description with an in-depth analysis of its features, screenshots,
together with links to relevant resources and reviews.
