Segurança | Guia para segurança em IoT

24/10/2016

A Cloud Security Alliance (CSA) lançou recentemente um guia sobre segurança em IoT, batizado de “Future-proofing the Connected World: 13 Steps to Developing Secure IoT Products”.

csa-iot-guide

O guia tem 76 páginas e identifica 13 recomendações principais:

Start with a Secure Development Methodology
Implement a Secure Development and Integration Environment
Identify Framework and Platform Security Features
Establish Privacy Protections
Design in Hardware-based Security Controls
Protect Data
Secure Associated Applications and Services
Protect Logical Interfaces / APIs
Provide a Secure Update Capability
Implement Authentication, Authorization and Access Control Features
Establish a Secure Key Management Capability
Provide Logging Mechanisms
Perform Security Reviews (Internal and External)

O documento é bem completo, pois além de descrever as recomendações acima, ele também inclui um capítulo sobre as necessidades e sobre os desafios relacionados a adoção de dispositivos IoT.

Esta é a iniciativa mais madura que eu conheço para discutir detalhadamente como tratar segurança no mundo IoT. Há um ano atrás, eles já tinham publicado um relatório inicial sobre este tema.

O relatório pode ser baixado gratuitamente do site da CSA.

5. Design in Hardware-based Security Controls The MicroController (MCU) Trusted Platform Modules Use of Memory Protection Units (MPUs) Incorporate Physically Unclonable Functions Use of specialized security chips / coprocessors Use of cryptographic modules Device Physical Protections Tamper Protections Guard the Supply Chain Self-Tests Secure Physical Interfaces

6. Protect Data Security Considerations for Selecting IoT Communication Protocols

7. Secure Associated Applications and Services

8. Protect Logical Interfaces / APIs Implement Certificate Pinning Support

9. Provide a Secure Update Capability

10. Implement Authentication, Authorization and Access Control Features Using Certificates for Authentication Consider Biometrics for Authentication Consider Certificate-Less Authenticated Encryption (CLAE) OAuth 2.0 User Managed Access (UMA)

11. Establish a Secure Key Management Capability Design Secure Bootstrap Functions

12. Provide Logging Mechanisms

13. Perform Security Reviews (Internal and External)
