Cybersecurity glossary

Clear definitions and expert insights,
supporting Askeal's mission to make cybersecurity more accessible.

Each glossary entry provides a clear definition, a detailed explanation of the concept, examples of how it works, common techniques or variants, its impact and risks, links to recommended external resources, and related topics for further exploration.

Advanced Persistent Threat APT

An advanced persistent threat refers to a structured and sustained intrusion by skilled adversaries who pursue long term objectives.

Amplification Attack

An amplification attack uses third party servers to multiply traffic toward a victim so a small request yields a large response.

Antivirus and Next-Gen AV (NGAV)

Antivirus and Next-Gen AV (NGAV) are endpoint protection technologies that detect and block malware. While traditional antivirus relies on signatures, NGAV uses behavioral and machine learning techniques to identify novel threats.

Application Layer Attack

Application layer attacks focus on exhausting resources at the web or API layer so legitimate requests fail to complete.

ARP Poisoning

ARP Poisoning (also called ARP spoofing) is a network attack in which an adversary sends falsified ARP (Address Resolution Protocol) messages to associate their MAC address with the IP address of another host, allowing them to intercept, modify, or block traffic.
