How To Shield Your PC From Net Attacks
As more computers become part of the planet wide network thanks to high-speed Internet connections, Internet security is starting to become an issue everyone should be worried about. These noxious programs can do a never-ending array of bad things: Swipe passwords, steal Visa card numbers, send spam from your personal computer, use your computer to attack other computers and masses more. Many folks feel rather overwhelmed or lost by what they perceive to be a complex and dismaying proposition, others ignore the issue completely. After you understand the threats and know one or two basic concepts, the issue is easy.
Long gone are the times when simply taking care about clicking on a file or a link was enough to protect you. Once this was only a problem for folk who traded illegal software, today viruses and trojans continually infect systems with no input from the user. Attacks are now cross platform and cross browser, using security holes present in assistant applications. A trojan can target user with no regard for browser or operating system.
Antivirus software is a good primary step but has limited efficacy. You would like to keep the criminal out of your home not tackle him after he is in your living room. The number one way to stop infections is to be sure each piece of software on your system is recent and keeping itself recent. Don’t ignore messages letting you know that a chunk of software must be updated. The great majority of updates are to close known security holes, these holes almost always have active exploits taking advantage of them.
Another security step that's ignored even by most security pros is using secure DNS servers. DNS servers are used to direct traffic to the correct web addresses. DNS servers can protect you in a number of ways. First, they can scan for and block sites for you; preventing your computer from even being able to get to a site trying to compromise your system.
2nd, just like anything else DNS servers can have security holes; many ISPs are loose about applying security patches to their DNS servers. Finally, changing your default DNS server may make it harder for a virus to modify it for you; many viruses will direct your PC to their own DNS server taking over all your Internet activity. There are plenty of free and secure DNS servers out there and setting one up on your system takes seconds.
