When is a security breach serious, less serious or not a breach at all?
Latest reports now online.
Our endpoint protection tests have always included targeted attacks.
These allow us to gauge how effectively anti-malware products, in use by millions of customers, can stop hackers from breaching your systems.
We penalise products heavily for allowing partial or full breaches and, until now, that penalisation has been the same regardless of how deeply we've been able to penetrate into the system. Starting with this report we have updated our scoring to take varying levels of 'success' by us, the attackers, into account.
The new scores only apply to targeted attacks and the scoring system is listed in detail on page eight of each of the reports.
If the attackers are able to gain basic access to a target, which means they are able to run basic commands that, for example, allow them to explore the file system, then the score is -1.
The next stage is to attempt to steal a file. If successful there is a further -1 penalty.
At this stage the attackers want to take much greater control of the system. This involves increasing their account privileges – so-called privilege escalation. Success here turns a bad situation worse for the target and, if achieved, there is an additional -2 penalty.
Finally, if escalation is achieved, certain post-escalation steps are attempted, such as running a key logger or stealing passwords. A final -1 penalty is imposed if these stages are completed, making possible scores for a breach range between -1 and -5 depending on how many attack stages are possible to complete.
We have decided not to publish exact details of where in the attack chain each product stands or falls, but have provided that detailed information to the companies who produce the software tested in this report and who have asked for it.

SE Labs uses current threat intelligence to make our tests as realistic as possible. To learn more about how we test, how we define 'threat intelligence' and how we use it to improve our tests please visit our website and follow us on Twitter.
