I graduated this year and am working in the security domain. I want to explore security topics and don't have a strong background since it was not part of our curriculum. Can you list some good security blogs which explore various security strategies. It could be any kind of security like network security, information security, SOA security, Identity, access, authorization etc.
Note: for developer-oriented resources, see this question:
What security resources should a white-hat developer follow these days?
