Cyber Security and Artificial Intelligence

Artificial Intelligence (AI) and Machine Learning (ML) are nowadays used in a
plethora of use cases across different industries and sectors: from getting new
movies recommendations on Netflix, to optimizing corporate processes, to driving
autonomous cars. Simply put, machine learning gives the ability for computers to
learn from past behavior and react to newly encountered input without requiring
prior explicit programming.

One of the areas that can benefit from the use of AI and ML is Cyber Security.
There is actually a significant number of articles online that discuss about how
AI helps in detecting and blocking cyber-attacks. While there is certainly truth
in this, it is also important to state that AI is not the silver bullet that can
magically solve all the challenges in the cyber security landscape.

How can Artificial Intelligence augment Cyber Security?

Broadly speaking, machine learning can be used in order to detect anomalies.
Anomalies are deviations from already seen behavior, and such deviations may
signify malicious behavior caused by attackers, malware, disgruntled employees
or other malicious entities. In particular, we distinguish two phases; the training
and the detection phase. During the training phase, the machine learning algorithm
is being trained by being fed existing data in order to build a model of what constitutes
normal behavior.
Once the system has been trained, we can enter the detection phase during which the system
is being fed with new, previously unseen data. Based on the model built during the training
phase, the system can now detect and flag anomalous behavior. Moreover, as time goes by,
the system can be continuously trained with new data in order to maintain or increase its
Detecting attacks (especially new, previously unseen ones) as they occur is the objective
that we are after and an appropriately trained machine learning system can help us achieve
this goal. Nevertheless, the key point in this generic machine learning process described
above is “training data”. In particular, for a machine learning system to be effective we
require a sufficient amount of “good”, labeled training data that will help define what
constitutes normal behavior and what constitutes anomalous, attack behavior.
Without good training data the system has high chances of missing attacks (false negatives),
or even so, flag normal behavior as malicious (false positives), both of which are equally as
important. A system with high false negative rate is obviously not considered effective in
terms of security. Nevertheless, a system which is very good at catching the actual attacks
(low false negative rate) but does so at the expense of mistakenly flagging a lot of innocent
activity too (high false positive rate) is also of rather limited usability. In the latter case,
increased manual inspection will be required in order to differentiate the actual attacks from
the false positive which may be ineffective or even impossible to perform correctly.
At this point, you might be asking “so, how hard is it to get good training data in order to
build a machine learning system that is actually useful?”. Well, the answer is, it depends on
the use case. For example, malware and spam detection are two example use cases where we typically
have millions of labeled samples that allow us to train a machine learning systems very well. On
the other hand, detecting attacks by inspecting network traffic is a use case that lacks good
training data which means that machine learning-based approaches in this area are not going to
be effective and robust enough.

There are of course many other cyber security use cases where machine learning can be applied,
but in all of them, with no exception, the effectiveness of machine learning-based solutions
heavily depends on the quality of the training data.

How does Futurae use Artificial Intelligence?

At Futurae, AI is used in a different way as to what has been described above. In particular,
AI enhances the security of ‘Adaptive Authentication’, Futurae’s innovative two-factor authentication (2FA)
solution. The beauty of Adaptive Authentication is that it is completely hands free for the user. Upon
authenticating to an Adaptive Authentication-enabled website, you would only enter username and password like
normally, yet still benefit from the increased security that 2FA offers. But how is this possible?
Adaptive Authentication is enhanced with Zero-Touch, which compares a few seconds of ambient sound captured by your phone and the computer
from which you are logging in. If the recordings of the computer and phone match, it means that the
two devices are close to each other, so it must be the legitimate user logging in (and not, say, a
hacker that stole their password). All this happens automatically and transparently in the background
while you log in, in a matter of few seconds. All that is needed is to have your phone somewhere
close to you and that’s it!

Where does AI come into play in Zero-Touch?

The audio comparison algorithm of Zero-Touch leverages machine learning in order to ensure high
accuracy in all cases, regardless of the type of ambient noise that is present in the environment.
For this Futurae researchers collected tens of thousands of audio samples and used them in order to
train the system and make it able to identify and categorize the recordings captured during Zero-Touch
execution into different categories, depending on their sound content. For example, they might be
categorized as music, human speech, animal sounds, urban sounds and so on. Depending on this
classification, the Zero-Touch comparison algorithm ensures high accuracy for the comparison result.
Of course, it is important that the whole process, besides being secure, happens very fast and
transparently during the login process. AI and Zero-Touch make sure that you stay both secure and happy!
