Securing Eureka in Spring cloud

Question

I am curious about what options I have for securing a service connecting (registering and getting disco info) to eureka. Obviously I want to turn security on in Eureka and specify a username password for service.

One question that I have is how do services trying to connect to eureka specify their credentials? Is it through the specification of the zone and what is the format of this reference?

*** I actually the answer to the above question and posted below, But still wonder about the following

As well, can I specify more strenuous security mechanisms and if so, which and how?

Answer 1

Ok, turns out that after you post an question is when suddenly you discover a way of doing.

I have figured out the part of my question:

in the Eureka server put this

security:
  basic:
    enabled: true
  user:
      name: user # login username
      password: password

In you service then put this

eureka:
  client:
    registerWithEureka: true
    fetchRegistry: true
    serviceUrl:
      defaultZone: http://user:password@localhost:8761/eureka/

After this services are authenticating to Eureka nd Eureka will reject any service without these credentials.

So Now to the second part of my question. What other ways can I secure this connection that are more secure?
