Stopping by Clouds on an Agile Evening

Alan S. Cohen,

There is a crispness in the air and all across the country the leaves are falling in the annual winter display. Winter always reminds me of American poet Robert Frost whom I studied carefully during my years living in Vermont. His famous work “Stopping by Woods on a Snowy Evening” was a simple verse play of opposites between the beauty and death in the woods and the safe journey home.


For those of us working the security beat in the current computing revolution — illustrated by cloud, mobile, microservices, and DevOps, to name a few — there is a similar sense of unease with the lack of hard boundaries of our critical data in a dynamic and distributed world. The pull of new technologies and new computing environments must reside side by side with the increased risk of a fast and agile world.

Rather than write in prose, I took a shot at verse to capture what I am observing in my corner of the security world. What most people do not know about Robert Frost is that he was born in San Francisco, so I am going to take literary license to suggest he might have written something like this if he was working in our day and age

Stopping by Clouds on an Agile Evening

Whose cloud this is I think I know.  
His data center is across the country though;  
He will not see the virus spreading here
To watch his applications brought low.   

My little firewall must think it queer  
To miss traffic between servers with a million rules near  
Between the PostgreSQL and the open Internet
The highest traffic day of the year.  

He gives his SIEM dials a shake  
To ask if there is some mistake.  
The only other sound’s the spinning
Of normal drives and cooling fans.  

The clouds are lovely, dark and deep,  
But I have promises to keep,  
And hackers to find before I sleep,  
And hackers to find before I sleep.
