protobuff vs json

 

Protocol Buffers (protobuf) and JSON (JavaScript Object Notation) are both data interchange formats, but they have some key differences in terms of usage, efficiency, and features. Here are some points of comparison:

  1. Serialization Format:

    • JSON: It's a human-readable, text-based format. It's easy to read and write for both humans and machines.
    • Protobuf: It's a binary serialization format. While it's not human-readable, it's more compact and efficient for data interchange.

  2. Data Types:

    • JSON: Supports a limited set of basic data types, including objects, arrays, strings, numbers, booleans, and null.
    • Protobuf: Supports a broader range of data types, including scalar types (integers, floats, booleans, strings), maps, nested structures, and more.

  3. Schema:

    • JSON: Schema is not explicitly defined, which means there is flexibility but less strict validation.
    • Protobuf: Requires a predefined schema (defined in a .proto file). This schema provides a contract for the data structure, enabling better interoperability and validation.

  4. Readability:

    • JSON: Human-readable and easy to debug.
    • Protobuf: Not human-readable in its binary form, which can make debugging more challenging.

  5. Size Efficiency:

    • JSON: Text-based, so it tends to be larger in size compared to binary formats.
    • Protobuf: Binary format results in smaller serialized data, making it more space-efficient.

  6. Parsing and Serialization Performance:

    • JSON: Slower to serialize and deserialize due to its text-based nature.
    • Protobuf: Faster serialization and deserialization due to its binary format.

  7. Language Support:

    • JSON: Widely supported across various programming languages.
    • Protobuf: Has official support for several languages, and third-party libraries/extensions are available for others.

  8. Usage Scenarios:

    • JSON: Often used for configuration files, web APIs, and scenarios where human readability is a priority.
    • Protobuf: Commonly used in high-performance and bandwidth-sensitive applications, such as communication between microservices, storage systems, and protocol-level communication.

In summary, the choice between Protocol Buffers and JSON depends on the specific requirements of your application. If human readability, simplicity, and ease of debugging are crucial, JSON may be a good choice. If efficiency, smaller payload size, and a well-defined schema for validation are more important, then Protocol Buffers might be a better fit.

Safety property that a deadlock can never occur

Identified four necessary conditions for a deadlock to occur 1. Mutual Exclusion. The nodes claim exclusive control of the resources they require. 2. Wait for. Tasks hold resources already allocated to them while waiting for additional resources. 3. No preemption. Resources cannot be forcibly removed from the tasks holding them until the resources are used to completion. 4. Cyclic Wait. A cyclic chain of tasks exists, such that each task holds one or more resources that are being requested by the next task in the chain.

OWASP API Security Top 10 vulnerabilities 2023

API Security Do's and Don'ts Don't trust input data for an API and do validate all inputs. Ensure you understand security and keep sensitive data out of code. Don't hardcode keys/tokens Don't reveal useful info in error messages. Don't have hidden/unadvertised features. Don't filter data in UI - control at app level Don't confuse authentication and authorization Always use API gateways to control access and traffic Do require API documentation. Do expect users/hackers to find and use undocumented endpoints Do continuous testing - attack simulation, test configs, fuzzing, injections OWASP API Security Top 10 Vulnerabilities 2023 API-1:2023 - Broken Object Level Authorization: BOLA is still the leading vulnerability that plagues APIs. When data objects do not have sufficient access controls in place, resources can be accessed by unauthorized users.
