Barclays hacks its own systems to find holes before criminals do

London

BARCLAYS plc is hacking its own computer systems to stay a step ahead of the criminals.

Troels Oerting, who joined as chief information security officer in February, set up a so-called red team in recent weeks to attack the digital defences of the London-based bank. His goal is to find any flaws and fix them before thieves, vandals or terrorists can exploit them.
