However, managing session expiration and ensuring that the session token is valid for the requestor becomes challenging. […]

Introduction In software development, third-party libraries are akin to the gears in a well-oiled machine – essential and powerful, yet requiring careful handling. While they bring efficiency and functionality, they also introduce security risks that can compromise your application. This article aims to guide developers through the labyrinth of third-party library security, offering best practices […]

Whether it’s school or car loans, you know that paying off your debt makes your life easier. It can improve your credit score, giving you more financial security. As a developer, you may also suffer from technical debt that impacts your application’s security. In a world where time to delivery is critical, you may make […]

Introduction Within the cascading bytes and bits of digital communications, developers forge pathways of data, threading information through the vast expanse of the internet. However, threats lurking within these pathways seek to intercept, manipulate, and exploit this data. This article ventures into HTTPS and Strict Transport Security (HSTS), offering developers a guide to comprehend, implement, […]

If you’ve ever had a toddler or a cat, you know they usually enjoy that box that an item comes in more than the item itself. In other words, you already know the first rule of business logic testing: the way people use applications isn’t logical.   As a developer, you have a set idea about […]

Another year, another Apache Struts 2 vulnerability that can lead to a major data breach. You may remember Apache Struts 2 from previous security alerts, like CVE-2017-5638, CVE-2020-17530, and CVE-2021-31805. When threat actors can find a vulnerability in the open-source web application framework, they immediately seek to create exploits. Typically, developers use the model-view-control (MVC) […]

While shell script syntax may feel clunky by today’s modern coding standards, shell enables productivity and collaboration.  On the other hand, many […]

Testing your application for business logic vulnerabilities is the digital version of a deep sea exploration. On the surface, you can identify various technical vulnerabilities, similar to how people snorkeling may come into contact with sandshark. However, the business logic vulnerabilities that hide within the application’s business logic are more difficult to detect and can […]
