Cyber Terminologies and Fundamentals

Definitions 

JavaScript Injection

A type of attack where malicious JavaScript is injected into web applications.

JSON Web Token (JWT) Security

Best practices to secure JSON Web Tokens used for authentication.

Jamming Attack

A cyberattack that disrupts wireless communications by overwhelming frequencies with interference.

Jailbreaking

The process of removing software restrictions on a device to gain unauthorized access.

Just-in-Time (JIT) Exploits

Attacks that target vulnerabilities in just-in-time compiled code.

Java Deserialization Vulnerabilities

Security risks associated with the deserialization of untrusted Java objects.

Job Control Security

Mechanisms to restrict unauthorized modifications to scheduled or running jobs in an operating system.

JTAG Debugging Exploits

Attacks leveraging JTAG debugging interfaces to gain low-level system access.

Java Security Manager

A security feature in Java that enforces access control policies for applications.

Java Cryptographic Architecture (JCA)

A framework that provides cryptographic functionalities in Java applications.

Jitter-Based Detection

A technique that analyzes network jitter to identify potential cyber threats.

Jump Server Security

Measures to protect jump servers used to access secure environments.

Jamming Resistant Networks

Techniques to prevent or mitigate jamming attacks on wireless networks.

Java Sandbox Bypass

Exploiting vulnerabilities to escape the Java security sandbox.

JWT Token Spoofing

An attack where attackers forge or manipulate JSON Web Tokens to bypass authentication.

JavaScript Keyloggers

Malicious scripts that capture user keystrokes to steal sensitive information.

Just-in-Time Access Control

A security approach that grants temporary access to resources only when needed.

Jaccard Similarity in Threat Intelligence

A technique used to compare and identify similarities in cybersecurity threat data.

Jump Host Compromise

An attack that targets jump hosts to gain access to secure networks.

JSON Injection

A security vulnerability where malicious JSON data is inserted into web applications.
