ACM.136 Posts by Teri Radichel on making use of the DRY Principal to Cybersecurity
In yesterday’s submit, I wrote concerning the how the time period abstraction will be utilized to cybersecurity. We’re going to modify some insurance policies in upcoming posts to attempt to stop privilege escalation by way of IAM insurance policies.
Carefully associated to that’s the DRY precept — don’t repeat your self.
You need to keep away from writing the identical code in a number of locations. As an alternative, create an abstraction and transfer the code that’s repetitive to the abstracted layer. Then lengthen the abstraction so that you don’t repeat the identical code again and again.
Please observe that though the DRY precept is sweet for cybersecurity and stopping bugs, it isn’t relevant to all fields and aims. I studied advertising and marketing in faculty a protracted, lengthy, time in the past. I discovered in an promoting class that an individual should see an advert at the least seven instances earlier than they keep in mind it.
The identical is relevant to studying and attempting to elucidate an idea. That’s why my mother and father, who had been college lecturers, used a way of giving their college students a timed check repeatedly to see in the event that they knew their math info. By the point any pupil obtained out of their class, they’d no downside immediately offering the reply to any single digit multiplication downside.
I’ve written concerning the DRY (Don’t repeat your self) idea numerous instances in several methods so I’ll refer you to the next posts for extra info. These posts clarify how and why you need to apply this precept of not repeating your self in cybersecurity insurance policies and utility programming code.
I don’t know who first got here up with the DRY princple however I examine it in a software program structure e book a very long time in the past. Sadly, I don’t keep in mind which one, however maybe it was one of many books referenced on the backside of this submit in Wikipedia.
