Evolve security automation like the human brain: Part 1

As our businesses become more digital, there are certain patterns
we can borrow from our own evolution to better model and improve our approach
to security and efficiency. There’s only so much that the security
professionals can do on their own as businesses grow more complex. To maintain
a strong security posture, you need to strike the right balance between
automated security processes and human ingenuity.

In all complex systems there is an element responsible for sense-making
and execution – for humans that is the brain. Let us for a minute draw
parallels to how the brain works and interacts with the rest of its parts. We
can examine these patterns and principals when deciding how to apply automation
effectively and responsibly to help your business become more efficient and
secure.

The Brain and the Body

Scientists have shown that the human brain has grown in
complexity and size largely due to environmental factors over millions of
years. While our digital businesses haven’t had the same amount of time to
develop, we can look analogously at information technology having its own
version of sensory organs, a nervous system, memory, and yes, even a brain-like
function.  

Our brains take in observations and with the proper
orientation and understanding, drive decisions and actions, some of which can
be automated. Much like how I don’t have to think about breathing as I write
this sentence, since it’s part of a well-managed set of motor skills that human
evolution has automated. What qualities does a process require to be a
candidate for this autonomous function? The answer to this question will serve
us well as we decide what is safe to automate and what is not.

The Lizard, Dog, and Primate

I’m going to talk about the brain in a functional manner.
For this example, let’s categorize the brain into a slight variation of the Triune
Model’s
three key functional parts: the lizard, the dog, and the primate. While
each of these sections provide vital functions and processes on their own, it’s
only when they work in tandem that they create a high-functioning and efficient
brain.

The lizard section of the brain handles autonomic bodily
functions like heartbeat and respiration. Being the highly automated section,
it is also responsible for behaviors like rigidity, obsessiveness, and
compulsiveness.

The dog portion wraps itself like a girdle around the
reptilian section – girdle in Latin is “limbus” which is why it is called the
limbic system. It is in charge of “feelings” which act like a form of currency
for what we should remember and an economy for our decision-making processes.

The newest section of the brain is the primate section. Its abilities
include the development of language, reasoning, and the ability to learn from
mistakes. Perhaps most important is the ability to interact with the dog and lizard
brain sections to make any necessary changes to improve performance and to take
charge when appropriate.

The Modern Business as a Brain

This modular architectural pattern parallels the functional
requirements necessary for our digital businesses to be efficient and secure. Artificial
intelligence (AI) and machine learning are similar to the lizard portion of our
brain example, providing your business with automated, but rigid security
measures. People like those in your SOC or other key security roles are like
the dog portion, working alongside the automated processes to ensure effective
and well-informed security decisions. Finally, business leaders are like the
primate section, processing the actions of the other two sections and using
what they learn to improve overall performance. We seek the same functional goals
which are:

  • Automate actions which are frequent, require the
    least latency, and are deterministic in their outcome
  • Ensure the brain is supplied with necessary and
    sufficient observations so models faithfully represent the external environment
  • Develop shared currency between sub-systems so
    the system has a way to distinguish what is an alert that needs to be acted
    upon and what is noise
  • Model the external environment so we can make
    more informed decisions and identify outcomes independent of execution

Just like how the sections in our model come together to
create a complete, functional, and efficient engine to help drive the human
body, effective automation requires a proper understanding of the roles that AI
and various human elements must play in our digital businesses. Be sure to join
me in part two of this blog next time as I take a deeper look at the functional
role AI and machine learning play. I’ll also discuss best practices for how
machine learning and AI should be used to help your business create a more
secure and well-automated ecosystem.
