Data Loss Prevention and Data Backup


It is not a good day at work for you when you realize you have lost an important document that you worked on for hours, or when you realize your hard drive has been completely wiped out. The importance of data backup may seem a bit repetitive at this point, but it does take more effort to replace the data once it is gone than it takes to back it up.

First off, you should have a backup schedule. You should also think about how you’re going to implement it. Will you hire someone to do continuous backup for you? Maybe you’ll just use backup tapes. Backup tapes may seem like a perfectly fine idea to you, but you need to keep in mind that if a disaster strikes on site, no electronic device will save your data unless it is in a remote location.

Continuous backup is a process by which your data is constantly backed up by frequent ‘snapshots.’ Remote backup is a process by which your data is maintained off site without having to manually transport your data. Manual transportation has proven time and again to be an unsafe measure. You may want to consider continuous remote data backup for your company to ensure the best security of your information.

Other measures to take include keeping your computers in cool, dry, areas that are free of dust. Use a generator – if there’s ever a power outage, you want your computer to stay on so that data doesn’t disappear because you didn’t get the chance to save it. In addition, antivirus software is essential for keeping your computer’s system healthy and decreasing your risk of losing data.

Preventing Computer Viruses

Far too many company and household computers become infected with viruses annually, and the affects of these infections can be devastating to the user. Since there are so many ways a virus can enter your computer’s system, it’s important that you know how to block off those entrances. Here are several ways to decrease the chances of your computer becoming infected:

-Don’t solely rely on anti-virus software, although you should have it installed. Be sure to update often to detect and protect your computer from the most recently created viruses.
(It also doesn't hurt to install a spyware, malware, and adware removal application)
-Read the headlines. Stay on top of the news to educate yourself about new viruses.
-Try not to open an e-mail attachment until you are sure it is safe. Make sure you know the person or why it may be sent to you.
-Once again, surf the web for news about viruses so you know common subject lines and file extensions relative to those viruses.
-Disable automatic attachment viewing in your e-mail settings.
-Set your Word and Excel settings so that Macros are disabled when a file is opened up for viewing.
- Use search engines that are well-known for generating results relevant to search terms. A site is probably safe if a lot of people have linked to it, but keep in mind that this isn’t always the case. This way, your chances of being directed to a site that hosts a virus is less likely.
-Make sure you set your security settings to ‘high’ in your web browser.
-Try to avoid downloading free applications from unverifiable websites.
-Configure your settings so that you can always view file extensions.

The following are examples of file extensions to be suspicious of when they show up in e-mail:

ADE, ADP, BAS, BAT, CHM, CMD, COM, CPL, CRT, DLL, EXE, HLP, HTA, INF, INS, ISP, JS, JSE, LNK, MDB, MDE, MSC, MSI, MSP, MST, OCX, PCD, PIF, POT, REG, SCR, SCT, SHB, SHS, SYS, URL, VB, VBE, VBS, WSC, WSF, WSH

It is easy to tell yourself you will regularly take these measures to maintain your computer security and implement virus protection, but it is also quite easy to forget. This is often how viruses end up finding their way into your computer.
