Why is Data Security Important?

Data security is very important or critical for most companies and businesses. Besides formal organizations, it is also very critical for home computer users as well. Information like client details, bank details, account details, personal files, etc. must be well protected for everyone on the planet because if it gets into wrong hands, it can be misused easily. Such information can be hard to replace and potentially dangerous. By securing such data or information, one can protect the files and avoid facing any difficulties.

Different data security measures:

1. Disk Encryption.
2. Software and hardware based ways to protect data.
3. Backups.
4. Data masking.
5. Data mirroring.

Data Protection Principles

Personal Data must be processed lawfully and fairly.
Personal data should be relevant, adequate and not excessive in relation to the purpose or purposes due to which they have been processed.
Personal data must be obtained just for one or more than one specified and lawful reasons and must not be processed in any way that is not compatible with those reason/reasons.
Personal data should be accurate and should be kept up to date wherever it is necessary to keep it up to date.
Personal data which is processed for any reason or reasons should not be kept for any time longer than required for that reason or reasons.

Data encryption

Disk encryption is one of the most commonly opted for data security technology or methods. This is a technology through which encryption of data on a hard disk drive takes place. This technology takes place in two major ways – software or hardware. In disk encryption, data is converted into unreadable codes that cannot be accessed or deciphered by anyone who is unauthorized. There are several ways and tools to carry out disk encryption, and these tools may vary in the security offered and features used.

Data mirroring

Discuss your definition and make an assumption which of today’s new terms best fit your definition
