will be helpful for those in need From the rules you shared it is applying the rules to the top level of Accessibility and not its keys meaning the new data includes the keys and its value e.g. ID-123: true below I restructured it to look at the id and makes use of the .isBoolean() function.
code :
  "rules": {
    "Accessibility": {
        ".read": true,
        "$id" : {
          ".write": true,
          ".validate": "newData.isBoolean()",

What rule will make my Firebase storage bucket accessible only to my Firebase Function in the same project?

By : Manjunath CV

I think the issue was by ths following , Cloud Functions run with administrative access to the project they're a part of. This means you can simply give no regular users access to the bucket, as Cloud Functions bypasses your rules anyway.
From the documentation:
code :
// Access to files through Firebase Storage is completely disallowed.
// Files may still be accessible through Google App Engine or GCS APIs.
service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write: if false;

To fix the issue you can do The Firebase Security Rules now support a length property for strings, as well as several other string methods including replace(), contains(), toUpperCase(), toLowerCase(), etc.
See https://firebase.google.com/docs/reference/security/database/#string_properties for more information.

Misra-C 2012 rule 10.1 boolean operand to be used in case where expression is of boolean type

Hope that helps Basically, MISRA-C wants us to treat logical/relational operators as if they returned a bool type (like in C++) and generally "pretend" that C has a distinct bool type that is separate from integers. This gives increased type safety when you use static analysis tools.
Which means that you have to be explicit with checks against zero:

How can one restrict Firebase Admin SDK to delete data from firebase database

wish helps you When accessing Realtime Database using the Admin SDK, it has unrestricted access to your database by default. Security rules don't apply.
The only way to restrict the Admin SDK is to initialize it with UID that forces it to behave as if it authenticated as user with that UID. This is described in the documentation using databaseAuthVariableOverride. There is also another answer on SO that describes what to do for nodejs. If you scope access like this, your security rules will have to specifically call out that UID in the rules to limit its access.
