When is a security breach serious, less serious or not a breach at all? Attack chain scoring is important in helping you find out.
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.
Attack chain scoring
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.
