Certificate Revocation Does Not Work!

One thing that’s very surprising about PKI infrastructure is the fact that a lot of the mechanisms put in place don’t work, or don’t work as they should. Often this is driven by sheer necessity, and the need to keep the internet working no matter what. One example of this is certificate revocation. If you are setting up a domain and requesting a new certificate, you would assume that once issued the certificate can be revoked in the case of a security breach.

But you’d be wrong. Even when you revoke the certificate attackers can still use it to enable MIIM attacks. Read on to see why….

REST -What It’s Good For (Part 2: Semantics and Information Sharing)

In my previous post, I detail how REST allows us to utilise the HTTP’s native caching functionality without the need for additional technologies or knowledge. However, this whole ‘using what we know about HTTP already’ philosophy goes much deeper than that.

Consider one of the biggest problems with API design and maintenance: getting your clients to use the API correctly, especially when it’s changing or is constant development. This might be easy if you are integrating with one team that sits next to you (and even then misunderstandings can arise), but what if you have multiple clients across the organisation, or if you API is public?
