How do we define Internet security? Things have changed since the earliest days of computer viruses and spyware. Today, Internet security is a very broad topic.
First of all, there is a bigger list of threats. Here are some of them:
Scareware (such as fake antivirus programs)
And several more
Many of these threats overlap and become part of each other. For example, Trojans deliver other malware like spyware and adware. Phishing can lead to rootkit infections and backdoors to hackers.
Some may only force you to view ads and do little harm otherwise. Others can turn your system into a “zombie computer” that becomes part of a “botnet” and is controlled by a “CC or command and control center”. This reminds of the Borg in the Star Trek movies. Remember “resistance is futile”? Yeah, that could be you.
Even a single threat like a specific virus sometimes gets reincarnated regularly. As soon as antivirus companies (AV companies) discover one and create a solution for it, the virus authors begin working on a variation that isn’t found by the solution, sometimes within hours. This means that the AV vendors are always behind the curve.
Corporate networks have the same problems that you do but on a much bigger scale. Their IT (Information Technology) departments work tirelessly to lock down the company networks so that only authorized traffic gets in or out and they steer clear of threats.
Generally, all of these categories and variations of threats are now just called “malware”. So, one way to define Internet security might be:
“Internet security is the attempt to protect computers and networks, while connected to the Internet, from malware and unauthorized access”
That’s just my definition, though. And to expand a little more, Internet security is a combination of human intervention and vigilance along with software security tools used at various points in a network and on computers.
As a side note, we want to protect them after they’re disconnected from the Internet as well because some malware has a delay action built in. Also, malware gets carried from computer to computer via flash drives and other storage devices.
So, to define Internet security might only take a sentence or two but it covers a whole lot of territory when you get into the details. Be sure to look around and get educated so that you can make sure you have a top Internet security solution too.
