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.

Let's Not Mess Around with Security on our Personal Systems Either!

Essential Security Practices for Your Personal Systems Ensuring a minimal level of cybersecurity, privacy, and availability on your personal systems means you need to manage the following essential practices. This is a brief overview of recommendations from sources like CISA, NSA, etc., focused on personal laptop, phone, and other systems' security. Anti-virus  I've found you'll get the best anti-virus protection and usability from a paid product - I've always had good luck with Norton labeled products. If you are looking for current vendor offerings see:  https://www.pcmag.com/picks/the-best-antivirus-protection Regardless of whether you choose to use a commercial product or open-source anti-virus tool, it is absolutely something you need to use. This is the minimally needed level of system security. Once installed, ideally, it should be invisible until there's a security problem it can't prevent or solve.   Backups You need to have at least a minimal level of ...

RACI, Cybersecurity and NICE Framework

The NICE framework from a RACI point of view The NICE framework ( NIST SP 800-181 rev. 1) established a standard approach for describing cybersecurity work, in order to help stakeholders share a common language and ideally improve how to identify, recruit, develop and retain talent. It breaks down cybersecurity work role categories into: Oversight and Governance; Design and Development; Implementation and Operation; Protection and Defense; Investigation.  Which is very cybersecurity-centric and not related to common tools for project management within companies. Especially smaller enterprises that do not have dedicated people to mange and coordinate cybersecurity needs. A  RACI chart  is   a project management tool used to define and clarify roles and responsibilities within a project team.   It stands for Responsible, Accountable, Consulted, and Informed, and visually represents who is responsible for what, who is accountable for the outcome, who needs to be c...

Typescript - It might not be easier, but but it's surely different

Typescript is a statically typed language, that is a superset of JavaScript. I've had the discussions and debates about that aspect of the language. I am all for static typing. Any way my tools can help me be better is alright by me. So I avoid the ' any ' type designation and make sure I have guards on ' unknown ' types, as much as I can.  Any  does not carry any useful type information, while unknown does, and allows it to enforce type checking.  Anything can be assigned to a variable of type unknown , but an unknown value cannot be assigned to variables of other types without explicit type assertion or narrowing. Similarly, no operations are permitted on an unknown value until its type is refined. This behavior ensures type safety and prevents runtime errors. (Refined with help from google). I bring this up because I was arguing with the compiler recently because I'd assumed both made no use on any type information in any circumstance - because I haven't ...
