Several Security Pitfalls to Avoid in Software Design
February 6, 2025
Developers concerned about security should check out "Seven Types of Security Issues in Software Design" at InsBug. The article does leave out a few points we would have included. Using Microsoft software, for example, or paying for cyber security solutions that don’t work as licensees believe. And don’t forget engineering for security rather than expediency and cost savings. Nevertheless, the post makes some good points. It begins:
"Software is gradually defining everything, and its forms are becoming increasingly diverse. Software is no longer limited to the applications or apps we see on computers or smartphones. It is now an integral part of hardware devices and many unseen areas, such as cars, televisions, airplanes, warehouses, cash registers, and more. Besides sensors and other electronic components, the actions and data of hardware often rely on software, whether in small amounts of code or in hidden or visible forms. Regardless of the type of software, the development process inevitably encounters bugs that need to be identified and fixed. While major bugs are often detected and resolved before release or deployment by developers or testers, security vulnerabilities don’t always receive the same attention."
Sad but true. The seven categories include: Misunderstanding of Security Protection Technologies; Component Integration and Hidden Security Designs; Ignoring Security in System Design; Security Risks from Poor Exception Handling; Discontinuous or Inconsistent Trust Relationships; Over-Reliance on Single-Point Security Measures; and Insufficient Assessment of Scenarios or Environments. See the write-up for details on each point. We note a common thread—a lack of foresight. The post concludes:
"To minimize security risks and vulnerabilities in software design and development, one must possess solid technical expertise and a robust background in security offense and defense. Developing secure software is akin to crafting fine art — it requires meticulous thought, constant consideration of potential threats, and thoughtful design solutions. This makes upfront security design critically important."
Security should not be an afterthought. But after a breach, it is going to be fixed. Oh, the check is in the mail.
