What are the short comings of SSL? (21 of 285 technotes for 2015)

SSL/TLS Shortcomings -

  • SSL is point to point - when the message reaches a peer server
  • SSL needs to be stripped off so that the message can be processed

SSL Limitations:

  • SSL is point to point - where as we need end 2 end security, as typical enterprise application has multiple layers.

  • SSL is transport layer security - not message level security - data in disk cannot be protected by ssl

  • HTTPS - does not support nonrepudiation well - critical for business
    • server can prove that a completed transaction was requested by a client (in case a dispute arises)
  • SSL does not support element wise signing - i.e. sign only the credit card details of the entire message.
