ACARM (Alert Correlation, Assessment and Reaction Module) is a tool that correlates alerts sent by host and network sensors into groups and in that way reducing the amount of messages that need to be viewed by a sytem administrator. There is a Web GUI that let’s the admin observe the different kinds of alerts with different graphical representations like, for example, pie charts, bar charts or more advanced. Different kinds of alerts are color coded on a color scale from green to red, green being just information, while red being critical.
