Cyber security isn’t just an issue for governments and corporations, but an issue we all face—that’s because the favorite weapon of hackers and terrorists is your computer.
Enemy #1: Your Computer
If you read any report about the latest hacking attack, you’ll hear about “botnets” or “millions of computers”. These are giant collections of computers just like yours which hackers now control.
Hackers don’t buy these computers—they break into them remotely and then they either use them for evil or sell them to someone else who will use them for evil.
Most people don’t realize that their computers have been taken over until days or weeks later. It could be that your computer is no longer completely under your control right now—you just don’t realize it yet.
What Hackers Do With Your Computer
The easiest type of attack on the Internet is the Distributed Denial Of Service (DDOS) attack. The hacker takes thousands or millions of computers and has each one of them repeatedly try to access a site as fast as possible. Since few sites on the Internet can withstand millions of requests a minute, the site can’t respond to legitimate requests from legitimate customers.
DDOS attacks come in several types. Some require a relatively small number of computers—say 100,000 to take down Google. But these small-scale attacks can be blocked after the company determines which computers are powering the attack.
Another DDOS attack uses large numbers of computers and very basic attacks. In this case it might take up to 10 million computers to take down a site the size of Google. Unfortunately, there’s no cyber security defense against this type of attack. Google’s only options are to buy (or rent) extra servers or to wait for the attack to finish, which usually happens when enough people discover their computers are being used in an attack.
Beyond The Basic Attack
DDOS attacks are the most basic tool hackers control. And it’s a pretty useless tool—all it can do is force a website offline. Sure that costs the website significant business, but it’s not the worst thing in the world.
There’s far worse hackers can do with your computer—for example, hackers can make a quick buck by using your computer to sell child pornography. It’s an illegal business with high profit margins and if the hacker uses your computer, he doesn’t have to worry about the police seizing his computer.
Hackers will also use your computer to run phising scams and perpetuate fraud.
Unfortunately, when the police discover fraud or child pornography, they rarely look beyond the person who owns the computer perpetuating the crime. If you own the computer, you own the crime.
Is Your Computer Infected Right Now?
As I mentioned, your computer could be infected right now. Hackers prefer you don’t realize that your computer is infected so you don’t try to get it fixed.
But hackers can’t hide all the signs of their activity on your computer. Slow Internet, strange errors, and suspicious disk activity all point to a compromised computer.
If you suspect your computer has been hacked, use your anti-virus software to run a full system scan. You may want to disconnect from the Internet while the scan is running to prevent your computer from being used in an attack in the meantime.
Protecting Yourself In Advance
The best way to stay out of jail and avoid gaining a reputation as a terrorist, hacker, or child pornographer is to block hackers from accessing your computer in the first place. Follow the standard advice offered here and from most other experts:
- Don’t install programs without first verifying that they’re free of viruses. The best way to do this is to use a trusted download site which reviews the software before your download it.
- Always run an anti-virus program. It will help catch infected email attachments and it will scan your hard drive regularly to ensure no viruses have infected your computer.
- Always run a firewall. The firewall will block hackers and viruses when they try to connect to your computer directly. The firewall won’t help if you become infected, but it will help keep you from becoming infected in the first place.
- If you see something suspicious on your computer, investigate it. Don’t ignore it and hope it goes away—that’s bad cyber security.
Install a program to your computer!
A software program will not upgrade your memory but it will clean out all the junk files, detect Malware, delete unused registry keys, Automatic Driver updates, and more. Not taking advantage of the latest updates and security patches can leave your computer vulnerable to attacks. At the moment I am using PC Matic to maintain everything for me. This software is amazing and has won a number of top awards. You can get a free scan for your computer to see how it works before you buy.
