SYNOPSIS

openvas-adduser

DESCRIPTION

The OpenVAS Security Scanner comes with its own user base which contains the list of who can use the services of openvassd, and what restriction (or rules) each user has.

openvas-adduser is a simple program which will add a user to the openvassd userbase.

The program is straightforward and asks for the following items:

• Login

the login name of the openvassd user to add

• Password

the password that the user will use to connect to openvassd

• Rules

the set of rules to apply to the user. See below.

RULES

Each user has his own set of rules. Rules are here to restrict the rights of the users. For instance, you can add user ``joe'' so that he can only test the host ``192.168.1.1'', whereas you can add user ``bob'' so that he can test whatever IP address he wishes.

Each rule fits on one line. A user can have an unlimited amount of rules (and can even have no rule at all).

The syntax is:

accept|deny ip/mask

and

default accept|deny

Where mask is the CIDR netmask of the rule.

The default statement must be the last rule and defines the policy of the user.

The following rule set will allow the user to test 192.168.1.0/24, 192.168.3.0/24 and 172.22.0.0/16, but nothing else:

accept 192.168.1.0/24
accept 192.168.3.0/24
accept 172.22.0.0/16
default deny

The following rule set will allow the user to test whatever he wants, except the network 192.168.1.0/24:

deny 192.168.1.0/24
default accept

The keyword client_ip has been defined, and is replaced at run time by the IP address of the openvassd user. For instance, if you want your users to be able to only be able to scan the system they come from, then you want them to have the following ruleset:

accept client_ip
default deny
