Intro
|
|
------------------------------------------------------------
|
|
|
|
As your trusted opensource security product, we do care a lot about security and with our regular release schedule we
|
|
try to stay ahead of possible incidents. Even though we are cautious and stay informed, sometimes issues
|
|
do occur, in which case it's good to know what to do.
|
|
|
|
|
|
------------------------------------------------------------
|
|
Staying ahead
|
|
------------------------------------------------------------
|
|
|
|
Even though we always encourage people to update regularly, sometimes it's not possible to do so for various reasons.
|
|
|
|
Luckily OPNsense comes with an integrated security check for known vulnerabilities, which can be found in our firmware
|
|
module. In which case you do have the opportunity to validate for yourself what the risk is to keep using the
|
|
current version for a bit longer.
|
|
|
|
You can reach it via :menuselection:`System -> Firmware` in the status pane, the button "Run an Audit"
|
|
will bring you right into the security report.
|
|
|
|
If all goes well, a report like the one below will be shown:
|
|
|
|
.. code-block::
|
|
|
|
***GOT REQUEST TO AUDIT SECURITY***
|
|
Currently running OPNsense 22.1.8_1 (amd64/OpenSSL) at Tue May 31 09:01:04 CEST 2022
|
|
vulnxml file up-to-date
|
|
0 problem(s) in 0 installed package(s) found.
|
|
***DONE***
|
|
|
|
|
|
.. Note::
|
|
|
|
We do not offer community support on assessing if incidents on older versions do warrant an immediate upgrade on your
|
|
end as this often depends on features used and settings configured. Our advise always will be to upgrade into the
|
|
latest community or business version.
|
|
|
|
|
|
.. Warning::
|
|
|
|
Please don't report issues to us reported by the security health check, they are already known and highly likely
|
|
a fix is pending for the next release.
|

Upstream vulnerabilities
|
|
------------------------------------------------------------
|
|
|
|
Since OPNsense is a collection of opensource software, when finding an issue, it is always a good idea to
|
|
inspect where is should be fixed first. In case you don't know or aren't sure, you can still ask on our end, just
|
|
know that we don't have the manpower to act as an intermediate between various projects.
|
|
|
|
|

|
|
Reporting an incident
|
|
------------------------------------------------------------
|
|
|
|
Security incidents on our product can be reported to our security team available at **security** @ **opnsense.org**.
|
|
|
|
All reports should contain at least the following information:
|
|
|
|
* A clear description of the vulnerability at hand
|
|
* Which version(s) of our product seem to be affected
|
|
* Any known workaround
|
|
* When possible, some example code
|
|
|
|
|
|
------------------------------------------------------------
|
|
Information handling policies
|
|
------------------------------------------------------------
|
|
|
|
As a general policy we do favor full disclosure of vulnerability information after a reasonable amount of time to permit
|
|
safe analysis and correction as well as appropriate testing for the correction at hand.
|
|
|
|
In order to coordinate with other affected parties, we might share parts of the information provided to us to them as well
|
|
or ask the reporter to do so.
|
|
|
|
When the submitter is interested in a coordinated disclosure process, this should be indicated in any submission to avoid
|
|
discussions later on.

Third party security verification
|
|
------------------------------------------------------------
|
|
|
|
Intro
|
|
............................................................
|
|
|
|
Within the OPNsense team and community we spend a lot of time safeguarding our software and keeping up with the latest threats,
|
|
like checking used software against CVE's on every release, implementing best practices in our development methods and
|
|
offering clear and transparent release engineering.
|
|
|
|
To even improve this further, we decided to bring a third party on board and mold a process around our security verification
|
|
by trained security professionals.
|
|
|
|
|
|
Business Edition
|
|
............................................................
|
|
|
|
As our business edition is aimed at professional users, it does make sense to offer additional safeguards, like even more extensive testing on
|
|
this product. Looking at the lifecycle of our software, this is also the most mature stage of what we do have to offer:
|
|
|
|
* Development version
|
|
|
|
- Available at every release, offers a glimpse of what to expect in the near future
|
|
|
|
* Community version
|
|
|
|
- When changes survive the development version, these are included in the community version, these are internally tested and
|
|
feedback has been offered by community members.
|
|
|
|
* Business Edition
|
|
|
|
- Functional changes are being included in a more conservative manner, more feedback has been collected from development
|
|
and community, leading to a mission critical version of your well known OPNsense firewall.
|
|
|
|
As security testing is quite time-consuming, we aim to offer a full qualification cycle at every major release.
|
|
|
|
|
|
Framework / Type of testing (LINCE)
|
|
............................................................
|
|
|
|
In our quest for a framework to use, we found the LINCE methodology.
|
|
|
|
LINCE is a lightweight methodology for evaluating and certifying ICT products, created by Spain's National Cryptologic Center (`CCN <https://www.ccn.cni.es/index.php/en/menu-ccn-en>`__),
|
|
based on Common Criteria principles and oriented to vulnerability analysis and penetration tests.
|
|
|
|
LINCE strengths over other methodologies mainly consist of reduced effort and duration.
|
|
However, the way in which it is applied also makes it possible to pay more attention to the critical points of each product,
|
|
giving more weight to concrete and practical tests that combat real threats than to dense documentation or exhaustive functionality tests.
|
|
|
|
As most frameworks are not intended to be repeated very regularly, together with `jtsec <https://www.jtsec.es/>`__ we came up with an approach which
|
|
makes it possible to pass the test twice a year, which is needed to align with our Business Edition releases.
|
|
|
|
During every cycle, there's always a chance that (small) issues appear which should be fixed, in close accordance with jtsec, the OPNSense
|
|
team prepares fixes for the findings and makes sure that these are included in a future (minor) release.
|
|
|
|
|
|
Steps in the process
|
|
............................................................
|
|
To better understand where a version of OPNsense is at in terms of verification, we distinct the following stages in the process, which
|
|
we will also note on the version at hand.
|
|
|
|
1. In test - Software delivered to jtsec, in process (interaction between OPNsense and jtsec).
|
|
2. Tested - Software verified / tested, documentation not yet published.
|
|
3. LINCE Compliant - Test complete including summarised report (by jtsec)
|
|
4. Certification pending - Offered for formal certification. (as of 2023)
|
|
5. LINCE Certified - Certified by CCN (as of 2023)
|
|
|
|
The certification steps are planned to be executed once a year starting in 2023, this process is quite time consuming, but
|
|
adds another independent party to the mix.
|
|
|
|
Timeline
|
|
............................................................
|
|
The first fully certified product has been a community version (21.7.1), which offered us insights into the process and
|
|
helped us improve the process which we would like to use for the business edition. We started this cycle with version 22.4
|
|
including full testing by jtsec and made plans for the future.
|
|
|
