Backup and Example Slides from MITRE

CEE Example ,[object Object],[object Object],[object Object],Example Log Messages Transport - successful log transmission Syslog (each log message is transmitted in a single UDP packet usually over port 514/UDP) Syntax - details specific to event being logged Format (3) CEF message CEF:Version|Device Vendor|DeviceProduct|DeviceVersion|Signature ID|Name|Severity|Extension Extension is a meta item – it imposes a sytax extension to specify addition details - a data dictionary can enumerate these details Syntax - details specific to event being logged Format (1 and 2) month day time host program[pid]: message In CEE, each of these would be a possible syntax element, whose value and definition would be well defined by a Data Dictionary Data Dictionary needed to enumerate details associated with the event It needs to provide flexible syntax options by defining the elements and formats Ex: dst in the CEF event – defined by a dotted quad IPv4 address

CEE Example (Cont.) ,[object Object],[object Object],[object Object],Taxonomy – a reduced language set for consistent log messages Right now they are semantically similar – ok for humans – but not for computers
