Authorization is still a problem in the CWE...

A common problem on the Common Weaknesses list is CWE-862: Missing Authorization. This happens when a product doesn't check a user's permissions before they access something.

Often this weakness is solved once you implement an access control system. This system typically asks users for their login information when they open the application. This is like securing the "front door" - you know who's coming in. At that point you may have solved the “Front Door” authentication problem, where you know who you are letting in.

But what about inside the application? Each resource (like data or features) should also be checked against the user's permissions. This is the “Authorization” problem. This is a critical design consideration for any application because it applies to everything from buttons on the user interface (UI) to internal parts (libraries) used by the application. The importance of these checks depends on how sensitive the application's information and features are.

For a deeper understanding of authorization testing, consider exploring the OWASP project's WSTG - Latest for Web Application Security Testing guide, specifically section 05-Authorization Testing.

Unit Testing - What to Test

This I wrote to answer a question that came up when we were discussing our software process and I was training developers on how to unit test. It seems a simple enough question, but I kept pondering it and delving deeper until I realized I needed to write this monograph. What unit tests should we write? How do we know what to test? Ideally, unit tests should cover every path through the code. It should be your chance to see every path through your code works as expected and as needed. If you are practicing Test Driven Development then it's implied everything gets a test. In the real world, you might not be allowed to test everything - for instance, if the testing suite ends up taking a week to run, then the world will have changed by the time it finishes and the test results will be obsolete. Unit testing at it's basic is testing an object, a method - the smallest unit of your code that it can test independently. It should test the inputs "goes into" an...

It's all broken...

So, Scott Hanselman struck a chord again: Everything's broken and nobody's upset . The worst part is I can see that I'm part of the problem on both sides . I've excused many problems with software - shrugging as I restart the software or reboot. I save my anger for those occasions where I fell I've lost serious work and substantial time. Other than that I accept problems, glitches, crashes as "the cost of doing business". I believe it's actually because I've amused myself and earned a living creating software, that I am able to accept what's often pitiable quality. I've spent time working on systems that are not much more than breadboards with wires cascading from it, where getting something, anything to work was a huge accomplishment. But that was then and this is now. No way would I put up with a car that suffers from numerous small problems as today's software can. And putting these two thoughts together, it's now frightening ...
