The data that you have created and stored inside of your computers and networks is the reason why you consider these things to be of value. Besides, having all of this data is the reason why you have bought your own computer or network. This is why you must make sure to protect all of your data at all times. If the applications and operating systems that you have installed on your computer will be deleted, you can always have them reinstalled. However, the same cannot be said with the unique data that you have created and stored. Once they get lost, unfortunately, you cannot get them back anymore.
Besides most data found on your computer to be more unique, some can also be highly confidential. Clearly, you do not want to lose it, and you also do not want other people to view it without your consent. You become a victim of identity theft when your credit card, social security number, and bank account information are exposed to people you do not know. Furthermore, company documents may include the financial records of your company, personal information of your client and employees, and your trade secrets.
Below are some ways in which you can secure your data and prevent its loss.
1. Utilize disk encryption
You see a lot of third-party products nowadays that enable you to encrypt data found on your entire disk as well as any removable devices that you have such as flash drives, USB drives, and the like. Disk encryption allows locking down of all of the contents found on your disk drive and removable devices. Data will be encrypted the moment it will be written on the hard disk and will then be decrypted before it gets loaded into memory. You can come up with a master password for your own use and some secondary passwords with access rights to other users.
2. Use a public key infrastructure
A PKI or public key infrastructure is a method of managing private or public key pairs and digital certificates. To protect the data that you will be sharing with your intended recipient, using a PKI allows you to encrypt your data with the public key of your recipient that can be accessed by anyone. However, the holder of the private key corresponding to the public key is the only person who can decrypt your data.
3. Protect data with IP security while in transit
Using a sniffer software, most expert hackers can easily capture your data while it is traveling over a network. To ensure that your data is well protected while it is in transit, you can utilize an internet protocol security system. Just be sure that both your receiving and sending systems are supported by this system. You can have your IP security setting configured using the properties option of your TCP/IP protocol. You can find this from the Options tab on your Advanced TCP/IP Settings. Most operating systems already come with built-in support for IP security. Just be sure that you have everything set appropriately.
