How do I protect data on my computer's hard drive?
Losing disk data is the worst thing that can happen to any computer user. Unexpected, often irretrievable damage is as high a threat as virus attacks or Internet data thieves. How to secure data on a computer?
How to protect data with a password and encryption?
First of all - it is worth setting a password for access to the computer and mobile devices. Also, laptops, due to the fact that they are portable, deserve additional protection in the form of an access password. From Windows, we can select "secured user profile" and set a password in the BIOS. In the latter case, first, when starting the computer, press the F11 (or F12) key - then we will get access to the motherboard settings. In this way, we make access to our data difficult, because the BIOS password reset can be done by removing the battery for several dozen minutes.
A particularly recommended option is file encryption. All you need to do is install an encryption program that can protect the entire disk or only selected files. You can choose one of the free apps, for example TrueCrypt, BestCrypt, or AzCrypt. Due to the fact that our files are encrypted, it will be more difficult for unauthorized people to get to them. The encryption algorithms work in layers, i.e. a potential intruder would have to deal with several barriers.
How to secure your data in a simple way? Hide files!
Sometimes it is also enough to use much simpler methods than encryption or generating passwords. If we have business files or those that we should especially watch over on our computer - use the option to hide the file. Just right-click on the object and then choose an option Properties, then selecting the option hidden. At this point, the file should disappear. You can regain access to hidden content by entering the Control Panel and then selecting the option Show hidden files and folders.
You can also make physical access to data difficult by hiding the icon thumbnail. Let's right-click on our folder and then on the option Adjustment in Properties (right mouse click). In the customization options, let's change the icon to a blank - then it will become transparent and we will only see the name of the folder. To hide its name as well, right-click Rename and press the key combination 0160 (keeping ALT pressed all the time). Ghost folder ready!
