24 hours in a Security Operations Centre (SOC) Part 3

The importance of supplier due diligence...

“G’day mate, I see you’ve had a busy one”. A message appears; our Australian SOC is open and preparing to take over from us in our ‘follow the sun’ routine. Whilst running proactive scans my mind starts to drift to my dinner plans; mmm, yes… I think a quarter duck would hit the spot. Suddenly I’m snapped out of it by a call from AcmeCorp…

I jump straight into reviewing their logs using our cutting edge Security Information and Event Management (SIEM) tool; we have some of the best technology in the world to monitor their systems, but there is nothing to show they have been hacked. How could hackers steal everything and leave no trace of anything untoward?

We gather the cybersecurity incident response team, quickly establishing that nobody had complained about a lack of service; that was until AcmeCorp’s Head of HR spoke up.

AcmeCorp hasn’t been hacked; but the cloud service has! The hacker has lied - they only showed us data from that breach. We investigate what data is held by this service, but it’s nothing more than we’ve already seen, thankfully the service was just being tested. I soon discovered that HR had purchased this service without telling anyone else. There had been no review of the provider’s security and they hadn’t investigated how the data they uploaded was handled.

This incident could have been much worse if they had uploaded more data with that provider. AcmeCorp has asked us to review their policies, so we will align them with ISO27001, ensuring there are sufficient safeguards for supplier management. We’ll also lead more training, so everyone understands how serious this could have been and only uses approved services in future.
