Glossary of Cyber Security Terms

JavaScript

JavaScript is a versatile scripting language that's the backbone of dynamic web development, used to enhance user interfaces and websites. However, it's a double-edged sword as it can be exploited for cross-site scripting (XSS) attacks, necessitating judicious usage in secure environments.

Jitter

In cybersecurity parlance, jitter or noise refers to subtle alterations of fields within a database while maintaining its overall useful characteristics. It's akin to a soft nudge that doesn't topple the balance.

Jitterbug

A Jitterbug attack is the digital equivalent of a disruptive whisper in a synchronized chorus, subtly manipulating signal timings to induce errors or compromise performance. The term is borrowed from a class of bugs that cause timing issues, especially in multitasking computer systems.

JSON (JavaScript Object Notation)

JSON is the bridge between humans and machines in data exchange. This lightweight data-interchange format is human-friendly to read and write while being machine-friendly for parsing and generating. It's often the preferred choice when data is sent from a server to a web page.

Jump Bag

A Jump Bag is the cybersecurity equivalent of a first aid kit, housing all the necessary items to respond to an incident swiftly. It's a precautionary measure designed to mitigate the effects of delayed reactions.

JVM (Java Virtual Machine)

A JVM is an abstract computing machine that enables computers to execute Java programs. Acting as the enforcer of Java's security model, JVM sandbox Java applications by default. However, several security considerations come into play when configuring and running a JVM.
