Applying the 80/20 Rule to Cyber Security Practices

How to look holistically across technology and processes and focus resources on threats that create the greatest damage.

The 80/20 rule, or the “Pareto Principle,” states that approximately 80% of effects come from 20% of causes, reinforcing a very powerful point that distributions are rarely equal. In sales, for example, 20% of clients often represent 80% of a firm’s revenues while in the field of software development, a relatively small number of the most-reported bug fixes are likely to create solutions for the overwhelming majority of problems.

For corporate information security officers and others on the front lines in the fight against cybercrime, the key takeaway is that not all threats create the same level of risk and that resources need to be prioritized to fighting those attacks that could do the most damage to your firm or industry.

Unfortunately, we continue to see too many instances where firms take a one-size-fits-all approach to their cyber defenses, focusing too many resources on lower-level risks, such as wide-scale malware campaigns, and not enough on the most destructive attacks or targeted probing by capable adversaries. In today’s rapidly changing cyber landscape, with threat actors growing in sophistication each and every day, this must change.
