A cyberattack that tries to gain unauthorized access to a network or exploit a security vulnerability. Also known as a breach or compromise.
A server that enables websites to communicate with each other over the internet by translating domain names into Internet Protocol (IP) addresses. It’s what gives websites their URLs.
Definitions
A type of malware that tries to hijack computer systems and use them for its gain. Malware can take many forms, including viruses and spyware, and is used to steal data, spy on people, or cause destruction.
A cyberattack technique involves a hacker using a list of passwords, names, dates of birth, and other personal information to gain access to an account. The attacker then uses their access to change the victim’s password or steal money from their bank accounts.
An attack technique that tries to get unauthorized access to a device or system by showing users unauthorized adverts, such as pop-up messages, new browser windows, and website add-ons. This can disrupt online experiences and cause computers to crash.
The smallest unit of information is sent over a network. Data is encrypted through a cybersecurity solution, so eavesdroppers cannot see what’s inside.

The term “jargon” describes the specialized vocabulary employed by a specific profession. This includes the cybersecurity field. It is essential for all involved in the field to have a clear understanding of the terminology. A list of cybersecurity jargon definitions is an excellent tool to help get everyone on the same page.
Cybersecurity is a set of logical/technical, physical, and personnel-focused countermeasures, safeguards, and security controls an organization uses to protect its information, systems, and networks from unauthorized access or harm. It involves both proactive and reactive security measures.
A botnet is a network of (often thousands) computers a criminal controls, typically without the owner’s knowledge. Criminals use botnets to send spam, attack websites in DDoS attacks, and sometimes even (using their combined computing power) crack passwords.
Each device in a botnet is clandestinely connected to criminal command and control servers via communication protocols. The bot herder sends instructions to the compromised devices in the botnet to perform certain activities like stealing data, sending spam, or carrying out DDoS attacks. The bots execute those commands on a massive scale and in large numbers.
Malicious software infects internet-connected devices such as computers, smartphones, and IoT devices. When a computer is part of a botnet, it becomes a zombie and may perform tasks like sending spam or DDoS attacks for the bot herder.
The good news is that you can protect your network against bots by implementing cybersecurity best practices, including setting hard-to-crack passwords, deploying strong multi-factor authentication, and ensuring all devices connected to the internet are running up-to-date software.
Examples
Many professions have their jargon, including cybersecurity.
A type of malware that can collect data from an infected device. Hackers often use this information to access a victim’s online banking account or social media profile.
The process of switching over from one system or network to another, typically to reduce or eliminate the impact on users should a security breach occur. A type of hacking attack that involves attackers using fake websites to lure victims into revealing sensitive information. It’s also known as phishing or spear phishing.
A hacking technique in which a hacker obtains a password by examining the scrambled representation of the password, known as the hash. The hacker then uses the hash to access the user’s account.
Organizations must follow standards to protect the information they store and process.
Glossary
Cybersecurity is a multifaceted profession requiring various skills to protect data and systems effectively. This glossary of cybersecurity terms will help everyone, from aspiring professionals to seasoned industry veterans, understand key concepts and vocabulary.
An attack in which hackers use a computer program to steal personal information, such as email addresses, passwords, and financial details. Hackers can use this data to access a victim’s account without authorization and exploit security flaws.
A type of malware that can multiply itself and spread to other computers and devices. Unlike viruses, which need human assistance to cause damage, worms can carry out attacks without any user interaction and do significant damage.
The lowest-level software on a computer makes it possible for the central processor unit to communicate with the operating system as the device boots up.
A computer that has been compromised by a malicious virus and has become part of a criminal botnet. Criminals use these machines for various activities, including sending spam emails and launching DDoS attacks against websites. They can also hack other users’ accounts by using their computing power to guess their passwords. This is often accomplished through phishing or other cyberattack methods.
A DDoS attack is a blunt instrument. It doesn’t net attackers’ private data or control over a target but can knock them offline.
DDoS attacks are growing in frequency and scope. Learn how to mitigate DDoS attacks by working with your provider to utilize scrubbing centers and services that filter traffic.
