Responsible programming
Excellent article! In your example of injection, the encapsulation would have to be prepared in such a way as to return multiple data. I am not sure most api would work this way, but it is certainly something to be aware of as sometimes developers do use such shortcuts and multi-purpose code.

When data is coming from a public source I believe that validation must necessarily occur using multiple factors, both for authentication and sanity checks. Perhaps there is more trust within a corporate shield, but these days this is rarely the case. Take for example a (trusted) employee using a BYOD device on corporate wi-fi, even with MAC validation.

Data Validation
It's all about the data validation.  OWASP has great documents on this, including: https://www.owasp.org/index.php/Data_Validation and https://www.owasp.org/index.php/Interpreter_Injection

In a nutshell:
  • Integrity checks - Ensure that the data has not been tampered with and is the same as before (checksums, logic in test code, etc)
  • Validation - Ensure that the data is strongly typed, correct syntax, within length boundaries, contains only permitted characters, or that numbers are correctly signed and within range boundaries
  • Business rules - Ensure that data is not only validated, but business rule correct. For example, interest rates fall within permitted boundaries. (extensive test scripts based upon code requirements)

Succinct anti-injection advice
Excellent, succinct advice on how to combat the injection attack. It requires more than most programmers are prepared to understand and do, but  there must be some way for greater programmer awareness and framework automated assistance to reduce the frequency of these attacks.

How Enterprises are Attacking the Cybersecurity Problem
Concerns over supply chain vulnerabilities and attack visibility drove some significant changes in enterprise cybersecurity strategies over the past year. Dark Reading's 2021 Strategic Security Survey showed that many organizations are staying the course regarding the use of a mix of attack prevention and threat detection technologies and practices for dealing with cyber threats.
