The Importance Of Data Security

Data security is the practice of keeping data protected from corruption and unauthorized access. The aim of data security is to make sure privacy is implemented in protecting personal data.

Data is raw information that is stored either in a database or somewhere lying inside your hard disk drive. It can be any kind of information you store, privately safe or publicly viewable. However, no matter how secured we want our data is, there comes a time that our private data are breached even though we know how to secure files into our system. Here, is where we mostly miss these things:

Data or files do not actually gets deleted in the drive. The operating system simply forgets where your file is located to make room for more files.

Selective file wiping. Involves the use of a file wiping software to delete the file in an irreversible manner. It writes random 0s and 1s to the file so the actual file is overwritten; therefore, no data are recovered.

2.Clean up the Entire Drive. This method instantly removes any hard disk mounted in your computer. An effective way if you have multiple drives to clean up.

Dead hard disks should not be thrown too because it also has files in it. The reason it become broken is not because of the files but only because of the hardware itself. So if, the platters are clean without damaged and minimal scratch it is recoverable. So here are some ways to make it permanently unrecoverable.

Use hard disk destruction machines. Hard disk destruction machines crush, grind, or saw the disk in half so that disk are completely unusable and the platters inside, irreversible. These kinds of machines are very expensive that is why there are hard disk destruction companies that can destroy drives but for a small fee.

If you don't want to use any kind of service to get your disk destroyed, you can destroy hard disk data yourself using common tools found at home like hammer, saw, or drill.
