Where are the boundaries for your cyber security?

There is only so much budget for your cyber security, so where you spend it needs to give you the best protection possible. When I am talking to clients, we quickly tick off anti-virus, hopefully a ransomware compliant back-up and possibly some advanced threat protection, and they think they are protected.

My opening gambit is then to take the management team through what Triple A, (Authentication, Authorisation and Accountability), means for their business operation and cyber security. A white board is helpful here as we build a model of their operation and the information within that, that needs managing.

Then we talk on.

We quickly get to staff training so the technical cyber security defences will be supported by a vigilant team. Then on to working from anywhere and that leads on to bring-your-own-devices and how the information the team has on those devices needs special attention. Read last week’s post on portable USB storage, if you want to know what I say about that and working from anywhere.

Then we come to something that often surprises the client – paper.

The dream of a paperless office has been spoken about, written about and promised for many years, but it never seems to get here. I get pretty close, thanks to OneNote, my smartphone’s camera and the functionality in the Microsoft 365 for Business app. Paper that is scanned into my system this way (business and personal) is saved into our business security structure. The paper is then shredded and recycled.

Then there is paper outside the office

I carry an A5, spiral bound notebook, as I cannot completely get away from paper, it is spiral bound to make it easy to photograph the pages and then destroy them. The notebook drops easily in my bag or even pocket keeping those confidential notes – confidential.

Diana (my partner at Smart Thinking and wife) and I have been watching a lot of television since last Thursday, when the death of Queen Elizabeth II was announced. We have a TV in the office. It was Diana who spotted Clive Myrie with his notepad on display whilst he was interviewing people outside St James’ Palace. That prompted this blog post. Now in my photo you cannot read the writing, I have blurred it, we were not watching in HD and I am sure there is nothing sensitive there, but it illustrates how, when under pressure, one of your team may carelessly give secrets away.

It happens to government papers

There has been research for a technical solution to this type of data leak (Fujikawa et al., 2012), but in this case training your team and having policies and procedures in place is probably the best solution.

One more thing about paper before I conclude. We work for a firm of solicitors who wanted to reduce costs on printers. We had to put in place a scheme that did not allow sensitive printouts to sit in printer hoppers for anyone, unauthorised staff or unauthorised visitors, to read.

So, the boundaries of your cyber security extend as far as you need them to and must include not only technical solutions but training, policies and procedures.
