68 - Internet and online security

Botnets

A botnet is a string of infected, connected computers coordinated

together to perform a task. Botnets gain access to your machine

through some piece of malicious coding. Once the software is

downloaded, the botnet will now contact its master computer and let it

know that everything is ready to go. Now your computer, phone,

tablet, or IoT device is entirely under the control of the person who

created the botnet. Most people who are infected with botnets aren't

even aware that their computer's security has become compromised!

What to do if you're infected: If you're infected you probably don't

realize it as bots are notoriously quiet. Your Internet Service Provider

might send you a notification alerting you that they found a threat on

your network and that you need to remove the bot. If you have a bot,

use internet security software like Norton Security to scan all of your

devices.

Viruses/Malware

"Virus" is the commonplace word for all malicious software programs

for years now; however, a virus is just one type of malicious threat. A

virus is classified as a self-replicating piece of malicious code that

travels by inserting itself into files or programs.

What to do if you're infected: Take steps to avoid infection by

staying protected with internet security software like Norton Security.

If you subscribed to Norton Security and think you may have a virus,

contact Norton's on-call technicians to help eliminate the virus.

Take special precautions when using public Wi-Fi

Public Wi-Fi is available just about everywhere, from the local coffee

shop to the hotels and airports you visit while traveling. While public

Wi-Fi has made our lives a little easier, it also poses security risks to

the personal information available on our laptops and smartphones. A

virtual private network (VPN) gives you online privacy and anonymity

by creating a private network from a public internet connection. VPNs

mask your internet protocol (IP) address so your online actions are

virtually untraceable as well as secure. One of the biggest security

risks on public Wi-Fi are man-in-the-middle attacks (MITM). These

attacks are akin to eavesdropping. Data is sent from point A

(computer) to point B (server/website), and an attacker can get in-
