Data security measures

10.1.3.2 describe security measures including the concepts: data back-up measures, encryption, mirroring

Data security measures

In the most basic terms, Data Security is the process of keeping data secure and protected from not only unauthorized access but also corrupted access. The main focus of data security is to make sure that data is safe and away from any destructive forces. Data is stored as rows and columns in its raw form in the databases, PCs as well as over networks. While some of this data may be not that secretive, other might be of private value and importance. But unauthorized access to such private information or data can cause many problems such as corruption, leakage of confidential information and violation of privacy.

Data erasure
Data mirroring

Data encryption

Data 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. Even though there are many benefits of using this method, there are also certain weaknesses or vulnerabilities.

Data mirroring

Data mirroring refers to the real-time operation of copying data, as an exact copy, from one location to a local or remote storage medium. In computing, a mirror is an exact copy of a dataset. Most commonly, data mirroring is used when multiple exact copies of data are required in multiple locations.

Backups

One of the easiest yet most effective ways to avoid data loss or to lose important and crucial files is by taking a backup of your data regularly. There are many ways to take backup and it is up to you how many copies of your data you wish to keep. While external hard disks are a common way to take backup, these days cloud computing too proves to be a cheap and easy way to maintain a backup of all files at a safe location. Of course, a backup won’t prevent data loss but would at least ensure that you don’t lose any information of importance.

How to backup data?

Individual work.
1. Select the Start  button, then select Control Panel > System and Maintenance > Backup and Restore.
2. Do one of the following:
If you've never used Windows Backup before, or recently upgraded your version of Windows, select Set up backup, and then follow the steps in the wizard.
