Computers are under constant threat from Trojan horses, viruses, worms and other malicious sources that can cause permanent damage. They’re also susceptible to theft and can be easily hacked, so it’s essential to protect your PC with asset tags and invest in some decent software.
Here are five ways to make sure your IT equipment is secure:
Install a firewall
Any computer connected to the internet is vulnerable to infiltration, so you must install a firewall. A firewall is a handy bit of software or hardware that acts as a barrier between your private computer and the public internet. It monitors incoming and outgoing applications and decides what should pass through to your system. Firewalls are particularly good at preventing unauthorised access and can stop hackers from invading your privacy. Windows Firewall is fairly basic, but it’s free and can be backed up with a hardware firewall – so there’s no excuse for not protecting your equipment. If you do wish to opt for something more sophisticated, commercial firewalls offer more comprehensive protection and could save you money in the long run.
Make the most of anti-virus software
Firewalls are great at fighting off worms, but other viruses can slip through the net. Therefore, it’s wise to install the latest antivirus software, to ensure your computer stays safe. The software will scan the files on your PC and will alert you if it finds anything suspicious. It’ll keep a look out for viruses that match a virus dictionary and will work hard to remove harmful files. Modern PCs often come with computer security programs; however, you must make sure they’re updated regularly – as new threats are appearing all the time. Free anti-virus packs are available online, but ensure you’re getting the optimum protection and don’t leave anything to chance.
Don’t open unknown attachments
One of the best ways to keep your PC secure is by deleting unknown attachments. Avoid reading emails from an unfamiliar contact and read up on dangerous viruses doing the rounds. Occasionally a virus or worm is spread via email and is sent round the world in a matter of days. It might contain a catchy subject line such as “view this world-famous image right now”, as this entices you to click on the email. If you do, harmful files might enter your computer system causing serious damage. If your friend’s PC has a virus, their computer might send out dangerous emails from their address – so be aware of this too.
Use different logins
Passwords are required to enter many sites these days, but it’s crucial to use different logins – in case one falls into the wrong hands. If someone sinister (like a computer hacker) gets hold of your codes, they could steal a wealth of personal information, so don’t make their job easy. It can be difficult to recall a number of long passwords, so try using the same one with a series of number on the end. Jot the numbers down in a notebook (without the main password) and this will help you keep on top of the game safely. It’s also wise to remember that secure sites will always display a small padlock icon. If they don’t, your information might be passed on, so don’t take risks.
Invest in asset tags
As well as securing your files, it’s also wise to protect the computer itself. You can do this by placing asset labels to your belongings, as this should keep them safe. These highly adhesive security labels can be bought from reputable stores and work to deter thieves. They show that the item is accounted for and leave a nasty mark when removed – decreasing their value and making them unattractive to steal. Opportunistic thefts are common, so do all you can to safeguard your expensive equipment.
If you own a PC make sure it’s well protected and keep your documents and personal files safe!
