Threat number. 1
Threat title. Hackers changing what the advertisement shows
Probability. Likely
Potential size of Moderate
loss / impact
level.
Risk severity. Medium
Explanation of If hackers were able to find a vulnerability in the system, they
the threat in could change the advertisement boards to show whatever they
context. like. This could be imagery that is offensive to some people or the
images are graphic. This would be bad for Brilliant Billboards
because people would think the organisation had something to do
with this, damaging their reputation.
Threat number. 2
Threat title. Unauthorised access of the keypads to the display devices
Probability. Unlikely
Potential size of Moderate
loss / impact
level.
Risk severity. Low
Explanation of When there’s nobody near the keypads for the display devices, a
the threat in stranger could gain access to them and change the material that
context. it’s showing. This would be bad because although it could be for a
few minutes, it would stop people from seeing the intended
advertisement. This could make the clients of Brilliant Billboards
angry because they have paid for their material to be shown on
the boards and are not getting what they paid for.
