Let’s be honest: we all go on the Internet too many times a day to count. From checking our email when we first wake up to seeing the score of the game near bedtime, our days are filled with the Internet, even in ways that we may not realized, like with connected devices. But one thing that you may not consider is your safety online. This glossary outlines some basic cybersecurity words and phrases that you should definitely know if you’re an Internet user. Let’s get started!
Internet Safety & Security Glossary

Antivirus: Software that is designed to prevent malware from harming a computer. Its functions typically include checking all executable files for signs of malware infection and scanning the computer’s file system for potentially infected files.

Their methods include stalking, threats, personal attacks and name-calling, betraying a victim’s sensitive and embarrassing information to the public for the purposes of ridicule, and defamation of character, including maliciously false accusations.
Cybercrime: Any activity that is a violation of the law and is carried out using computers and the Internet.
Cyberstalking: The act of tracking, harassing, or otherwise stalking a person online.
Firewall: Security software or hardware that serves as a protective shield for a computer or network. Its purpose is to filter all incoming and outgoing data to prevent malware or malicious information from entering the system and prevent the unauthorized distribution of information outside of the system.

Monitoring software: Software that enables parents to monitor their child’s Internet use, including emails and websites visited.

Examples include phishing, leaving malware-infected USB drives around for curious people to insert into their computers (baiting), and tricking businesses into divulging customer information (pretexting), which is a tool often used by private investigators as well as cybercriminals.
Trojan: A form of malware that pretends to be something benign and useful in order to access sensitive files and information, install spyware, or otherwise make a computer vulnerable to hackers.
