NESSUS a one of scanner network security that use by administrator system. role NESSUS a to security audit a system.
like vulnerability,
misconfiguration,
security path that not yet to application,
default password, and
denial of service.
NESSUS functions to monitoring a network traffic.
Audit NESSUS as follows :

each security test write as external plugin. white features like this, we can white easily add test that we want without to read from engine NESSUS code.
2. NASL (Nessus attack scripting Language)
NASL is a language that to design for write program security test white easily and fast. in addition to NASL, c language also can use to write program security test.
3. UP-TO Date security vulnerability database.
4.client-server architecture
NESSUS security scanner consist from two sections that is:
a server that function as actor attack, and a client that functions frontend.client and server can run on the system that different. meaning from this feature is that whole network can to audit through a PC, white server that doing attack to network target.
5. can to testing value many host in the tie that same.
6.smart service recognation.
NESSUS not believe host that target use standard port that determinate by IANA. this meaning NESSUS can know a web server that running on the port that not a standard port (exaple in port 8080), or a FTP server that running on port 31337.
7. multiple services
when are two web server on host targets then NESSUS will testing both the web server.
8. Complete report
NESSUS not only give known weakness from network target but also to give way that can to use to prevent the bad guy to exploits weakness from network and also give level risk from a problem that found.
