Chapter 3      Understanding Intrusion and Correlation Data Structures
  Intrusion Event and Metadata Record Types
Security Zone Name Record
The eStreamer service transmits metadata containing information on the name of the security zone 
associated with an intrusion event or connection event within a Security Zone Name record, the format 
of which is shown below. (Security zone information is sent when the Version 4 metadata flag—bit 20 
in the Request Flags field of a request message—is set. See 
.) Note that the 
Record Type field, which appears after the Message Length field, has a value of 
115
, indicating a 
Security Zone Name record. It contains a UUID String data block, block type 14 in the series 2 set of 
data blocks.
String Block Length
uint32
Number of bytes in the client application URL String data block, 
including eight bytes for the string block type and length fields, 
plus the number of bytes in the URL string.
Encoding
string
Encoding used for the event extra data, for example, IPv4, IPv6, or 
string.
