Jailbreaking

Jailbreaking is the process of removing software restrictions imposed by the manufacturer or operating system provider on devices such as smartphones, tablets, or gaming consoles. It allows users to gain root access or administrative privileges to the device’s operating system, enabling them to bypass limitations imposed by the manufacturer or customize the device’s software and […]

Java Deserialization Attack

A Java Deserialization Attack is a type of security vulnerability that occurs when an application deserializes untrusted or malicious data sent by an attacker, leading to remote code execution, denial of service, data manipulation, or other security compromises. This vulnerability arises from insecure deserialization practices in Java-based applications that allow attackers to exploit the deserialization

JIT Compiling Security

Just-In-Time (JIT) compiling security refers to the measures taken to ensure the safety and integrity of the JIT compilation process within software applications and runtime environments. JIT compilation is a technique used in programming languages and runtime environments where code is compiled from a high-level representation, such as bytecode or intermediate language, into native machine

JSON Web Token

A JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained format for securely transmitting information between parties as a JSON object. JWTs are commonly used for authentication and authorization in web applications and APIs, providing a stateless means of communicating claims or assertions between a client and a

Just Enough Administration

Just Enough Administration (JEA) is a security feature in Windows Server that allows administrators to delegate specific administrative tasks to non-administrative users or groups in a controlled and restricted manner. With JEA, organizations can enforce the principle of least privilege by granting users only the permissions necessary to perform their assigned tasks, reducing the risk

Just-in-Time Access

Just-in-Time (JIT) access, also known as dynamic or on-demand access, is a security principle and approach aimed at providing users with temporary and limited access to resources, systems, or data only when needed and for the duration necessary to perform specific tasks or activities. JIT access is designed to minimize the attack surface, reduce the
