What steps can one take to secure personal data?
The steps or actions one can take to secure personal data are part of the concept behind personal computer data security. Before we can delve deeper into this concept, we need to enumerate some of the ways personal computer data can leak out--then and only then can we determine ways we can secure personal data. Here are the most obvious and common ways you can leak personal computer data:
- You lose the device containing personal computer data
- your laptop
- external hard drive
- USB thumb drive
- You unknowingly install a trojan on your computer
- You unknowingly install spyware on your computer
- You respond to an official looking e-mail from your financial institution asking you to login in order to resolve account issues
- You make such information available on your online profile (e.g. on Facebook)
Now that we know what can lead to your personal computer data to leak out unexpectedly, we can begin looking at actions that can help prevent such loses if and when such things happen. Each example listed above belongs to classes of ways personal computer data can be lost or can leak out. They are:
- loss of computer or data storage device
- victim to malware infection
- victim to phishing
- direct disclosure to online social networking sites
There are measures one can take to secure personal data and computer data. I will enumerate them below along with which class above they counteract.
- For loss of computer or data storage device
- External storage. Don't put personal data in your computer hard disk drive, instead store them externally online or in external storage devices like a USB thumb drive) . If you lose your laptop, you can buy another one to replace it with no personal data loss.
- File/volume encryption software. Regardless of where you store your personal data, you should encrypt files containing personal data or store them in encrypted disk volumes, so that if you lose your storage device or your computer is compromised by some form of trojan or spyware, no one can read your personal computer data.
- Against malware infection
- Firewall/internet-web filter. Setup your computer's firewall, and install an Internet or web filter software or solution. Doing so can help prevent you from getting infected in the first place; or if you do, it can prevent the infection from sending back your personal data to a malicious hacker.
- Antivirus/Antispyware software. Install some form of anti-malware software on your computer. This is just common practice and common sense. If you don't have one, get one. Trojan or spyware infection can allow a malicious hacker to steal your personal data/information.
- Against phishing
- Internet-web filter. Install an Internet-web filter solution. Most solutions will prevent you from accidentally going to malicious web sites which can steal your personal information or data.
- Self-education. Educate yourself about the best way to handle e-mails from your financial institutions. Find good sources of information online and learn about how to deal with e-mail so that you don't accidentally divulge personal information to malicious hackers. A good common sense solution is never click on any link e-mailed to you, unless you know how to tell if the link is legitimate. If it looks like your bank is asking you to login to their web site, don't click the link in the email; instead open your browser and type your bank's web site there.
- Against disclosure of personal data to online networking sites
- Self-education. Educate yourself about the online capabilities of your online networking site, and use its privacy tools to limit disclosure of any personal information you may have there.
- Limit disclosure. Better yet, limit what personal information or data you disclose on your online profile, or any site for that matter.
- You lose the device containing personal computer data
