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) […]
