The Yin and Yang of Security Patching

 

My computer is working, don’t change anything.

As an IT manager I observe this behavior regularly with end-users and product managers of eCommerce applications. It’s understandable. When a computer system is working and doing its job then “updates” are sources for creating failure. Updates change code. Updates rock the boat.

If a computer security update hasn’t bitten you yet, then it’s probably just a matter of time. My experience is the number of system issues related to operating system updates is growing.  It’s hard to test all the dependencies of code updates against every combination of hardware and software that exists on computing equipment. A couple of examples I can point to in 2017 are Microsoft Edge no longer working after installing the Windows 10 Creators Update.  Then there was the issue of Microsoft Outlook unable to open attachments which was later resolved with another hot fix.  

But we all know security updates are necessary. Why would we risk our personal data to thieves? In a business setting, why would put our customer’s data at risk? Why would we put the reputation of our business at risk?

Therein we find the yin and yang of security updates. We don’t want to upset the balance of a stable system, but we need to update the system so that it can remain stable in the future.

In the name of audit controls and security principles.

In the business environment, audit standards require staying up-to-date with security patches. ISO 27001/ISO 27002 and SOC2 have controls specifically addressing vulnerability patch management policies and procedures. To meet the requirements of the controls, a discipline in process and procedure is required.  These standards are there to help nudge all of us to change because we all know we resist change.

Plug those security gaps or face the consequences.

The consequences of not installing security patches can be devastating. In the worst case of cyber theft reported thus far, Equifax was robbed of information for 143 million individuals. The attackers found a weakness because Equifax failed to patch a known security vulnerability in website code they use.

Now hundreds of millions of people are exposed to the whims of criminals. The reputation of a large credit bureau is blown. The two highest ranking security officials within Equifax are out of a job. Patching known security vulnerabilities is serious business.

Complementary forces at play.

The next time someone schedules a security update for a system or application, understand the potential consequences fully. Intruders are at the gates. They make a living on our resistance to change.  But if we support the change and work with administrators to report any malfunctions, we can all help to build a safer tomorrow.  That’s how another yin and yang can make a more complete whole.

Onward and upward!
