This plugin just sets global variables (SID, SERVICE_NAME, etc.), and does not perform any security checks.

This plugin is an internal dependency used by several Nessus scripts. It does not perform anything by itself.

This plugin configures miscellaneous global variables for Nessus port scanners. It does not perform any security check.

The Nessus scanner testing the remote host has been given SMB credentials to log into the remote host, however these credentials do not have administrative privileges. 

Typically, when Nessus performs a patch audit, it logs into the remote host and reads the version of the DLLs on the remote host to determine if a given patch has been applied or not.  This is the method Microsoft recommends to determine if a patch has been applied. 

If your Nessus scanner does not have administrative privileges when doing a scan, then Nessus has to fall back to perform a patch audit through the registry which may lead to false positives (especially when using third-party patch auditing tools) or to false negatives (not all patches can be detected through the registry).

The remote host appears to be running Novell NetWare.  This operating system has a history of crashing or otherwise being adversely affected by scans.  As a result, the scan has been disabled against this host.

This script offers a way to control scanning of certain categories of network devices and hosts that are considered 'fragile' and might crash if probed.

This plugin configures various options and variables used by some Oracle plugins. 

By itself, it does not perform any security checks but may change the behavior of others.

OS Security Patch Assessment is not available for this host because either the credentials supplied in the scan policy did not allow Nessus to log into it or some other problem occurred.

This script just sets global variables (telnet/rexec/rsh logins and passwords) that are used to perform host-level patch level checks.

You should avoid using these cleartext protocols when doing a scan, as Nessus will basically broadcast the password to every tested host.

This script just sets global variables (SNMP community string and SNMP port) and does not perform any security checks.

This plugin displays, for each tested host, information about the scan itself :

  - The version of the plugin set.
  - The type of scanner (Nessus or Nessus Home).
  - The version of the Nessus Engine.
  - The port scanner(s) used.
  - The port range scanned.
  - The ping round trip time 
  - Whether credentialed or third-party patch management     checks are possible.
  - Whether the display of superseded patches is enabled
  - The date of the scan.
  - The duration of the scan.
  - The number of hosts scanned in parallel.
  - The number of checks done in parallel.

This plugin lets a user enter information about the Kerberos server that will be queried by some scripts (SMB and SSH) to log into the remote hosts.

This plugin initializes the SSH credentials as set by the user.

To set the credentials, edit your scan policy and go to the section 'Credentials'.

This plugin logs into the remote host using SSH, RSH, RLOGIN, Telnet, or local commands and extracts the list of installed packages.

If using SSH, the scan should be configured with a valid SSH public key and possibly an SSH passphrase (if the SSH public key is protected by a passphrase).

This plugin configures miscellaneous global variables for Nessus plugins. It does not perform any security checks but may disable or change the behavior of others.

The host seems to be an AppSocket or socketAPI printer.  Scanning it will likely waste paper.  Therefore, port 9100 won't be scanned.

The remote host appears to be a network printer, multi-function device, or other fragile device. Such devices often react very poorly when scanned. To avoid problems, Nessus has marked the remote host as 'Dead' and will not scan it.

This host has an IP address known to be a wildcard record for a top- level domain (TLD) or for a host within the 'nessus.org' domain.  It has been blacklisted and will not be scanned.

This plugin puts the content of cgibin() in the KB so that the function cgi_dirs() can work properly.

This script logs onto a web server through a login page and stores the authentication / session cookie.

This plugin sets various SMTP parameters because several checks need to use a third-party host/domain name in order to work properly. The checks that rely on this are SMTP or DNS relay checks. By default, 'example.edu' is being used for this purpose. However, under some circumstances, this may leak packets from your network to this domain, thus compromising the privacy of your tests. While the owner of example.edu is not known to keep logs of such packet traces, you may want to change this value to maximize your privacy.

Note that you absolutely need this option to be set to a third-party domain. This means a domain that has nothing to do with the domain name of the network you are testing.

This plugin configures Nessus so that it knows if it should query local information on each host or information pertaining to the domain (ie: requests will be forwarded to the PDC). 

If you test a single workstation, you want information about the domain.  If you test the whole network, including the PDC, you won't want redundant information. 

See the plugins preferences panel for details.

This plugin provides the username and password credentials for common servers, such as HTTP, FTP, NNTP, POP2, POP3, IMAP, IPMI, and SMB (NetBios).

Some plugins will use those credentials when needed. If you do not provide the credentials, those plugins will not be able to run.

Note that this plugin does not do any security checks.
