When you think about it, the most sensitive part of your computer is the data stored in it. There is just too much important information that can be accessed using your computer and if some of these information becomes known to someone other than you, that could spell disaster for your way of life.
Many data in your computer are confidential. Not only will you not want to lose it, you won’t even want someone viewing them without your authorization. Unfortunately, many opportunists would love to access your data to get your sensitive information. You’re probably familiar with the term “hacker” and you have an idea of what they do. They access your information and use it for their gain. You can be a victim of identity theft, credit card scam, and other internet crimes if you are not careful with your data.
In this day and age, you need to protect your data at all cost. Here are the things that you can do to protect your data from hackers and unauthorized users.
1: Back up early and often
To protect your data, you should back up early and often. This is one of the most important steps that you can take to protect your data from data loss and other data corruption issue. You can schedule backups automatically if you want. Many OS support automatic backup so you are covered.
2: Use file-level and share-level security
Creating permissions to your data files and folders is another thing that you can do to keep unauthorized users from accessing your file. If you have data in network shares, you can control which files can be accessed by other users. However, this permission security won’t work for someone using your local computer. If you share your computer with someone else, you will need to use file-level permissions.
3: Use disk encryption
You can download many third-party products that allow you to encrypt entire disk. Whole disk encryption allows you to lock down the entire content of the disk drive/partition. Only the user who initiated the encryption is allowed to view the files. For other users, all they see are the data in ‘outer’ disk.
4: Protect your transit data using IP security programs
Your data can be had while it is traveling over the network by a hacker. To protect your data in transmission, you can use IPsec when transmitting data. Most OS have built it in on their system so that hackers can’t read what is sent over networks.
5: Store important data offline
With all the NSA news right now, whatever you do, your computer that is connected to the internet may already be compromised by the NSA. The only thing you can do here aside from being very vigilant on your internet activity is to avoid storing sensitive information online. If you can, just save the most important files in a hard-drive that can’t be accessed over the internet.
