Audio steganography is a technique for hiding information within an audio file so that only the intended recipient knows of the hidden data’s existence. This method belongs to the broader field of steganography, which itself is a subset of security systems and comes from the Greek words “steganos,” meaning covered, and “graphein,” meaning writing.

Steganography is the practice of concealing a message, file, image, or video within another message, file, image, or video. Unlike cryptography, which focuses on making a message unreadable to unauthorised parties, steganography aims to hide the message’s existence. The word “steganography " is derived from the Greek words “steganos ,” meaning “covered ,” and “graphein ,” meaning “to write.”

Serialisation in Java is implemented to convert the state of an object into a byte stream, which can be quickly persisted to a file or sent over a network. This process is essential for persisting object data, supporting network communication, and facilitating sharing of objects between different parts of a distributed system.

Contextual analysis in cybersecurity involves examining events, actions, or data within the broader context of an organization’s IT environment. It is a critical component of a proactive cybersecurity strategy, aiming to understand the significance of activities by considering various factors surrounding them. This multifaceted approach helps cybersecurity professionals identify and respond to potential threats effectively.

CWE stands for Common Weakness Enumeration. It is a community-developed list of software and hardware weakness types that can serve as a common language for describing, sharing, and identifying security vulnerabilities in software systems. CWE aims to provide a standardized way of identifying and categorizing vulnerabilities, making it easier for software developers, testers, and security professionals to discuss and address security issues.

What is - Input Validation? # Input validation is a process used to ensure that the data provided to a system or application meets specific criteria or constraints before it is accepted and processed. The primary goal of input validation is to improve the reliability and security of a system by preventing invalid or malicious data from causing errors or compromising the system’s integrity.

A subdomain takeover is a type of cybersecurity vulnerability that occurs when an attacker gains control of a subdomain of a website or a domain name. This attack can seriously affect the security and functionality of a web application or website. In this explanation, we’ll look at subdomain takeovers, how they work, the risks they pose, and how to prevent them.

In this post, we will look at another method of infection. These are the attack vectors via domain names. This can happen at the main level, i.e. the domain itself, or via sub-domains. But what exactly is a domain takeover attack?

I will introduce you to the serializer from the EclipseStore project and show you how to use it to take advantage of a new type of serialization. Since I learned Java over 20 years ago, I wanted to have a simple solution to serialize Java-Object-Graphs, but without the serialization security and performance issues Java brought us. It should be doable like the following…

Test-driven development (TDD) is a software development approach that prioritizes writing automated tests while creating the actual code. There follows a cycle of writing a failed test, writing the code to make the test pass, and then refactoring the code. TDD was originally developed to ensure the quality, maintainability and expandability of the software created over the long term. The specific knowledge about the individual source text passages should also be shown in the tests. Thus, a transfer of responsibility between developers is supported. Better than any documentation, tests are always up-to-date regarding the function that has been implemented in the source code.

Supply Chain Security is a hot topic these days. And more and more, we as developers are dealing with this daily. But what does this mean for us, and how is this influencing our job? I want to give an overview of common attacks against the Software Supply Chain from the developer’s view and will introduce the Open Source project SLSA from the Linux Foundation.
