CASE STUDY T esco, one of the world’s largest retailers of consumer goods, needed a multi-factor authentication (MFA) solution that would provide visibility over account access and ensure sensitive employee data didn’t end up in the wrong hands. With the exception of its banking operation, Luke Fairless is responsible for overseeing cybersecurity strategies across Tesco’s range of operations, including its Express businesses, superstores and metros in the UK, Ireland, Europe, Asia and other global offices. His team looks after everything from risk compliance through to digital forensics, the Security Operations Centre and identity access management. Fairless is also tasked with ensuring security awareness and education across all 450,000 colleagues in offices, shops and distribution centres. We discover why Tesco selected the OneLogin solution and how it is already providing benefits for the major retailer. 64 INTELLIGENTCIO The challenge Tesco is increasingly using cloud services and while it is only office staff and store managers that have access to email, the wider workforce is accessing pay slips from the cloud. “Anybody working in stores or distribution centres, as well as offices, need to be able to log into that,” said Fairless. “And we want to be able to protect it because pay slips have got a lot of information on them that you could use to try and do an identity takeover of somebody. “Increasingly, we want to be able to make these self-service so if you need to change your bank account details then you can just do it yourself online rather than needing to go through your personnel manager. “If you’re allowing people to do that though, you can imagine an attacker could change that bank account detail to their own just before the monthly paydays. “And then suddenly, people’s salaries don’t end up in their own bank account, they end up in a fraudster’s bank account. “So, the need to be able to protect those accounts is crucial and it’s been a need that we’ve been able to see for a year or two, but we can increasingly see it as a need as we go forward.” The solution Enterprises are now required to have a second factor of authentication in place as username and password information – something you ‘know’ – are increasingly easy to pass on to attackers, even if only accidentally. Fairless turned to OneLogin for a solution, won over by the ease of use and partnership approach the vendor was able to offer. The second factor now used by Tesco employees is a mobile phone – something which employees ‘have’ and much harder for attackers to access. www.intelligentcio.com
