The ICSA Anti-Virus Certification Scheme
DOS/Windows/Other Platform Certification Process
http://www.icsa.net/html/certification/
--------------------------------------
Properties of Anti-Virus Certification
--------------------------------------
ICSA tests and certifies that anti-virus scanners pass a number of
stringent tests. The testing adheres to the following criteria:
- Testing performed by an independent organization Testing performed
by an unbiased organization
- Tests done on the most current version of the products
- All major products are tested
- All significant platforms are used for testing
- Tested on an on-going basis (at least monthly)
- Test criteria are objective
- Tests are "real-world" oriented
- Tests check for viruses "in the wild"
- Test criteria are made public
- Tests are "peer-reviewed"
- Anti-virus product developers are consulted
- Independent anti-virus experts are consulted
- Large corporate users of AV products are consulted
- Large computer security firms are consulted
- Test results are made public
- And, the certification can be revoked for the failure of a product
to maintain these standards.

The ICSA Certification Scheme for DOS/Windows and Other Platforms
-----------------------------------------------------------------
The old ICSA certification scheme required products to detect 90% of
the ICSA virus library. This was carried out on a release-by-release
basis (ie was version number dependent) and was designed to ensure
that certified products had 'adequate' virus detection capabilities.
While this testing methodology gave the user some information about
the efficiency of the software, it does not fully address the real
threat. It was for this reason that the new scheme was developed.
Note that the new scheme is still in it's infancy, and that new tests
will be being added month by month.
When one studies the epidemiology of viruses, one notices that
although there are 6000+ viruses known for the IBM PC or compatible,
there are only a couple of hundred 'in the wild' (that is, actively
spreading on PCs). A list of such viruses is maintained by Joe Wells.
By collating statistics provided by over 30 contributors from many
different countries, Wells' tracks those viruses which are reported.
Participants in the list include all the major anti-virus software
developers, and several independent researchers. The list is broken
down into two parts: an upper list, for viruses which have been seen
by two or more participants, and a lower list, which is made up of
those viruses seen by only one participant.
The new ICSA certification scheme is designed to focus on the real
threat to corporate PCs: those viruses known to be in the wild. In
order to be certified, a product must pass the following tests:
1. Certified products must detect 100% of all those viruses defined
as 'in the wild' according to the upper part of the Wild List. As
new viruses are discovered all the time, the Wild List used is
the one which was current two months prior to the date of the
certification test.
2. Certified products must still detect a minimum of 90% of the ICSA
virus 'Zoo', made up of samples of some of the 6000+ other
viruses known.
These tests are carried out with the product running its default mode
of operation, with the exception of using any appropriate logging
facilities.
-------------------------
Certification Maintenance
-------------------------
Once a product is certified, ICSA will attempt to recertify the
product a minimum of 4 times per year. Each certification attempt
will be carried out without the prior knowledge of the developer.
This helps to ensure that every release of the product is capable of
meeting the certification criteria, not just a special
'certification' version.
If a product fails either test I or II, the vendor will be given 7
days to supply a fix for the problem, and make this fix publicly
available. If this time limit is not met, the product will be removed
from the certified product list available from this Web site. This
list will be maintained in such away that a product's certification
history (passes and failures) will be visible.
Once a product has been decertified, certification can only be
regained when the vendor ships through its normal distribution
channel a version of the product which is certifiable. A special fix
just sent to ICSA for testing is not acceptable.
---------------------
Collection Management
---------------------
One of the most important factors to consider when carrying out a set
of detection tests on anti-virus software is the way in which the
virus library is managed. It is also vital to know which vendors (if
any) have access to the actual test samples used, and the way in
which the library is created.
No sample used in the ICSA 'in the wild' test-set is sent out to any
vendor. However, should a virus be missed during a certification
attempt, a replicant of that sample (note that this is not a copy of
the actual sample) will be sent out to the vendor for inclusion in
the next release of the product. This process ensures that vendors
have reliable detection algorithms for each virus in the collection.
In the case of a polymorphic virus, multiple copies of each virus is
used, to ensure that the product tested can detect that virus with
accuracy. Copies of individual replications of each virus from within
this test-set are not made available to vendors; thus, the test is
carried out against an 'unseen' collection of files. In order to pass
this test, the product must detect every replication in the test-set.
All viruses in the collection are attached to standard Goat files,
ensuring that no 'first generation' samples are in the collection.
Furthermore, should a virus be missed during certification, a check
is made to make certain that the file is not corrupted and is
capable of replication.
