The Scale Cube: Achieve Security Through Scalability

May 14, 2019  |  Posted By: AKF

AKF Scale Cube
If AKF Partners had to be known for one thing and one thing only it would be the Scale Cube.  An ingenious little model designed for companies to identify how scalable they are and set goals along any of the three axes to make their product more scalable.  Based upon the amount of times I have said scalable, or a derivative of the word scale, it should lead you to the conclusion that the AKF Scale Cube is about scale.  And you would be right.  However, the beauty of the cube is that is also applicable to Security.

Xtra Secure

The X-Axis is usually the first axis that companies look at for scalability purposes.  The concept of horizontal duplication is usually the easiest reach from a technological standpoint, however it tends to be fairly costly.  This replication across various tiers (web, application or database) also insulates companies when the inevitable breach does occur.  Planning for only security without also bracing for a data breach is a naive approach.  With replication across the tiers, and even delayed replication to protect against data corruption, not only are you able to accommodate more customers, you now potentially have a clean copy replicated elsewhere if one of your systems gets compromised, assuming you are able to identify the breach early enough.

One of the costliest issues with a breach is recovery to a secure copy.  Your company may take a hit publicity wise, but if you are able to bring your system back up to a clean state, identify the compromise and fix it, then you are can be back on your way to fully operational.  The reluctant acceptance that breaches occur is making its way into the minds of people.  If you are just open and forthright with them, the publicity issue around a breach tends to be lessened.  Showing them that your system is back up, running and now more secure will help drive business in the right direction.

SecuritY

Splitting across services (the Y-Axis) has many benefits beyond just scalability.  It provides ownership, accountability and segregation.  Although difficult to implement, especially if coming from a monolithic base, the benefits of these micro-services help with security as well.  Code bases that communicate via asynchronous calls not only allow a service to fail without a major impact to other services, it creates another layer for a potential intruder to traverse.

Steps that can be implemented to provide a defense in depth of your environment help slow/mitigate attackers.  If asynchronous calls are used between micro-services each lateral or vertical movement is another opportunity to be stopped or detected.  If services are small enough, then once access is gained threats have less access to data than may be ideal for what they are trying to accomplish.

Segmenting customers based upon similar characteristics (be it geography, spending habits, or even just a random selection) helps to achieve Z-Axis scalability.  These pods of customers provide protection from a full data breach as well.  Ideally no customer data would ever be exposed, but if you have 4 pods, 25% of customer data is better than 100%.  And just like the Y-Axis, these splits aid with isolating attackers into only a subset of your environment.  Various governing boards also have different procedures that need to be followed depending upon the nationality of the customer data exposed.  If segmented based upon that (eg. EU vs USA) then how you respond to breaches can be managed differently.

Now I Know My X, Y, Z’s

Sometimes security can take a back seat to product development and other functions within a company.  It tends to be an afterthought until that fateful day when something truly bad happens and someone gains unauthorized access to your network.  Implementing a scalable environment via the AKF Scale Cube achieves a better overall product as well as a more secure one. 

If you need assistance in reaching a more scalable and secure environment AKF is capable of helping.
