Chapter 4      Understanding Discovery & Connection Data Structures
  Host Discovery and Connection Data Blocks
Integer (INT32) Data Block
The Integer (INT32) data block is used in List data blocks to convey 32-bit integer data, for example, in 
the Vulnerability Reference data block where it is used to transmit a list of vulnerability identification 
numbers.
The Integer data block has a block type of 7 in the series 1 group of blocks.
The following diagram shows the format of the integer data block:
The following table describes the fields of the Integer data block:
Vulnerability Reference Data Block
The Vulnerability Reference data block describes the list of vulnerabilities to which a host is subject, 
including the affected port, protocol, server, and list of related vulnerabilities. The Vulnerability 
Reference data block has a block type of 8 in the series 1 group of blocks.
Note
An asterisk (*) next to a series 1 data block name in the following diagram indicates the message may 
contain zero or more instances of the block.
