Description
This type of operating system probe attempts to determine an estimate for how predictable the sequence number generation algorithm is for a remote host. Statistical techniques, such as standard deviation, can be used to determine how predictable the sequence number generation is for a system. This result can then be compared to a database of operating system behaviors to determine a likely match for operating system and version.
Prerequisites
• The ability to monitor and interact with network communications.Access to at least one host, and the privileges to interface with the network interface card.
Consequences
• Confidentiality: Read Data
• Confidentiality, Access Control, Authorization: Bypass Protection Mechanism, Hide Activities
