Does Your Company Have a Data Destruction Policy?
There are various ways carrying out data destruction, depending on the finality of the results required – this article outlines a few of those methods below.
The first method we will discuss is the art of destroying data by overwriting it with gibberish data. Programs have been made with the sole purpose of doing so, hour after hour, day after day, just to overwrite the data on a disk. Overwriting several times over on a disk seems reasonable to completely erase the data. For some, this method just isn’t secure enough and these customers demand a more permanent data destruction solution.
Encryption is a different way to ruin the data. While effective, it is actually somewhat wimpy since the data would still be there, and all you’d need to have is actually a key to access it. It does not even matter how tricky or convoluted the key is. The data is there, and it is actually only a matter of time before you can get the data out.
Yet another approach of data destruction is degaussing the disk. This means getting a potent magnet, and it is your choice no matter whether it is actually unidirectional or alternating, and apply the magnetic field over the disk. Tiny areas on the disk known as magnetic domains are magnetically attracted to your magnet, reorganizing the disk in random methods in reaction to your magnet. However, the data is still there, only randomized in chunks. And as long as the data is there, the data could still be retrieved.
Yet another approach shows far more promise. This technique, referred to as physical destruction would be to apply bits of pressure on the physical disk about a zillion times per second and hammer and smash it like the villain that it really is. Imagine what a paper shredder does to paper, then replace the paper having a disk, along with the paper shredder with about a million additional paper shredders. And run the disk numerous times by way of the million shredders.
But still, the tiniest bit of the disk can contain essential data, and this still just isn’t total destruction.
The final approach is known as phasing. It really is a much more expert way of saying you nuked the disk. Phasing is altering the state of the disk from a solid state to a gaseous state, by applying heat was above its melting point. With absolute certainty, this really is total data destruction of the data on the disk.
This really is complete and utter data destruction. It truly is completely particular that no info can ever be retrieved from the disk. To be fair, it can be with absolute certainty that the disk itself will in no way be retrieved . The only strategy to retrieve the data would be to apply data destruction procedures to the ones who wrote the precise information on the disk. Data destruction anyone?
