greenbone-security-assistant (UI for OpenVAS)
This is the UI the Open Vulnerability Assessment System (OpenVAS).
###### Known Problems ######
- PDF report generation is broken. This may get fixed in a future slackbuild.
- The libssh-0.5.4 shipped with Slackware (at the time of this writing) is
broken. If you need to run "credentialed" scans against targets running
OpenSSH 6.7 or beyond (including Slackware), you have 2 options:
1. Enable diffie-hellman-group1-sha1 as a KexAlgorithm in the sshd_config
of your targets.
2. Update your libssh to the latest.
You also may have problems with targets running Dropbear SSH server. See
this thread on LinuxQuestions for more information:
http://www.linuxquestions.org/questions/showthread.php?t=4175533193
- All the daemons run as root. There's no (working) configuration options
or documentation to change this behavior.
- There are a number of tests that depend on other software packages that are
not available as slackbuilds at this time. Stay tuned.
- If you're running in a VM environment, or on a headless server, then
installing haveged is recommended, particularly for step 11 below.
###### Upgrade Notes ######
If you're updating from OpenVAS-7 to OpenVAS-8, please note the following.
(See: http://www.openvas.org/install-source.html if you're unsure which
version you're running.)
Openvas now uses redis as a temporary database while running scans. You will
need redis installed and running, as well as hiredis. See step 2 below on
how to configure redis.
Before running openvas-manager, you'll need to migrate the database. Simply
run:
# openvasmd --migrate
###### Installation Instructions ######
These instructions assume you're familiar with slackbuilds. If not, please
refer to http://slackbuilds.org/howto/ .
1. Build and install hiredis.
2. Build and install redis. You need to uncomment the following 2 lines in the
/etc/redis/redis.conf file:
#unixsocket /tmp/redis.sock
#unixsocketperm 700
Now start up redis:
# sh /etc/rc.d/rc.redis start
3. Build and install openvas-libraries.
4. Build and install openvas-scanner.
5. You need a Certificate Authority and server certificate. Run the following
command:
# openvas-mkcert
6. You need the NVT's (Network Vulnerability Tests). Run the following
command to sync. In the future, you can do this through the
greenbone-security-assistant interface. This will take a minute or so
with a blazing fast internet connection. YMMV.
# openvas-nvt-sync
7. Start the openvas-scanner daemon.
# sh /etc/rc.d/rc.openvassd start
8. Build and install openvas-manager.
9. You need client certificates for manager to talk to scanner. Use the
following command.
# openvas-mkcert-client -n -i
10. Initialize the manager database. This will take a while, so be patient.
# openvasmd --rebuild
11. You want encrypted credentials in the DB, so do this now.
# openvasmd --create-credentials-encryption-key
This may take a while, so it's best to create some entropy by skipping to
#13-#15 and then coming back, if needed.
12. Create a user.
# openvasmd --create-user=cary
If you find the assigned password hard to remember, you can change it
right now.
# openvasmd --user=cary --new-password=mekmitasdigoat
13. Sync SCAP data. This will take some time.
# openvas-scapdata-sync
14. Sync CERT data.
# openvas-certdata-sync
15. Update port names.
# wget http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xml
# openvas-portnames-update service-names-port-numbers.xml
# rm service-names-port-numbers.xml
16. Start the openvas-manager daemon.
# sh /etc/rc.d/rc.openvasmd start
17. Build and install libmicrohttpd.
18. Build and install greenbone-security-assistant.
19. Launch the greenbone-security-assistant.
# sh /etc/rc.d/rc.gsad start
20. Point your browser at https://<YOUR IP OR HOSTNAME>:9392
You'll get a certificate error, of course (fixing this is left as an
excercise for the reader). Log in with your username/password from #10.
21. [Optional] Build and install openvas-cli. You'll need this if you ever
want to script tests.
That's it! If you run into any problems, you can try running the
openvas-check-setup script found here:
https://svn.wald.intevation.org/svn/openvas/trunk/tools/openvas-check-setup
If you don't have a web-server running, you can edit the /etc/rc.d/rc.gsad
script to remove the "-p 9392" option, and it will run on port 443.
Please let me know if you run into any problems. Patches welcome!
Have Fun!
