Communication network security risk exposure management systems and methods are disclosed. Risks to a communication network are determined by analyzing assets of the communication network and vulnerabilities affecting the assets. Assets may include physical assets such as equipment or logical assets such as software or data. Risk analysis may be adapted to assess risks to a particular feature of a communication network by analyzing assets of the communication network which are associated with that feature and one or more of vulnerabilities which affect the feature and vulnerabilities which affect the assets associated with the feature. A feature may be an asset itself or a function or service offered in the network and supported by particular assets, for example.
