An IT guy I used to work with (who will remain nameless), previously worked for the Alliance & Leicester, he was tasked with patching in some new kit over the weekend in the main server building for them.
Now to use BACS, you have to have a main connection into your system and a backup connection, once a week the backup connection is used for a whole 24 hours to verify it is functional and also to allow maintenance, this is part of the rules for having BACS I am told.
So as he is setting up the new kit, he contacts the central IT team to get 6 port numbers he can use to connect up the new server, which the central IT team give him, he queries this as there are cables in there, but they asure him that they are not being used for anything, so he un-patches them all and adds in the new server, all works and everyone is happy...
.. That is until Thursday, when at midnight the BACS system swithces to the backup server, which is running fine and is showing up on the network as fine!
However the 6 cables on the floor in the comms room are not receiving anything from the outside world, resulting in all oayments inbound to the A+I failing and no person getting paid or any money arriving, when this is picked up the bank discovers that they are now missing a 7 figure sum of money from their accounts and a huge amount of interest has been lost.
The weekend after the entire companies network was re-logged correctly. |
