You scored 46

OUT OF WHAT?

The business, the world, your boss, your client, want you to tell them that they are not going to be the next headline, they are not going to be hacked, they are safe, that the money that they have spent on cyber security has delivered them from the cyber evils of the world.

So yes 46.

That's a number right? Metrics and certainty in an uncertain world - businesses run on metrics, cyber security runs on caffeine.

How do you know your security is right?
How do you know that you are getting your moneys worth?
How do you justify your existence?

So lets look at it, strip away PowerPoint, bell curves and NPS scores and figure out what matters and how to tell people that yes, they scored 46 out of it depends....


When we are bombarded with metrics from vendors, from news, from insurance companies, how do we make sense of it all?

Cyber Security Professionals are there to protect the business, but how do you distil this into a number that makes sense to the business?

If you are getting a service from a vendor - how do you know what they should be reporting? Is it true - is it snake oil?

Bad goals and metrics = bad outcomes

If your team doesn't seem happy - are they just grumpy or is there a problem?

Have you bought the silver bullet of security controls or have you been sold a lemon?

When you don't understand the numbers, or how they are made, what the jargon means is there any point to looking at that graph?

This talk looks at numbers, goals, metrics and statistics from the viewpoint of a vendor, a customer and a cyber security professional.

TLDR - we need to do better.
