Maurine is working as a security consultant for Hinklemeir Associate. She has asked the Systems Administrator to create a group policy that would not allow null sessions on the network. The Systems Administrator is fresh out of college and has never heard of null sessions and does not know what they are used for.

Why would an attacker try to create a null session with a computer on a network?

Correct Answer:A
The Null Session is often referred to as the "Holy Grail" of Windows hacking. Listed as the number 5 windows vulnerability on the SANS/FBI Top 20 list, Null Sessions take advantage of flaws in the CIFS/SMB (Common Internet File System/Server Messaging Block) architecture.

Using these null connections allows you to gather the following information from the host:
- List of users and groups
- List of machines
- List of shares
- Users and host SID' (Security Identifiers)
