Microservices - Service Mesh
How can a service mesh improve security between microservices?
ABy encrypting traffic and enforcing access policies between services
BBy storing all service credentials in a public database
CBy disabling authentication between services
DBy merging all services into a single monolith
Step-by-Step Solution
Solution:

  1. Step 1: Understand security features of service mesh

    Service mesh encrypts communication and enforces who can talk to whom using policies.

  2. Step 2: Exclude insecure or unrelated options

    Storing credentials publicly, disabling authentication, or merging services reduce security.

  3. Final Answer:

    By encrypting traffic and enforcing access policies between services -> Option A

  4. Quick Check:

    Service mesh security = Encryption + access control [OK]
Quick Trick: Service mesh secures traffic with encryption and policies [OK]
Common Mistakes:
MISTAKES
  • Thinking credentials are stored publicly
  • Assuming authentication is disabled
  • Believing services are merged for security
