Careless homeworkers increase security risks

CIO Jury: But there's no reason why they should…

Careless remote and home-working staff are opening up corporate IT networks to an increased risk of damaging security breaches.

A survey by Cisco this week found a lack of discipline and vigilance among home workers on the internet - from hi-jacking the neighbour's wi-fi to opening unsafe emails and lending non-employees their work PCs or laptops.

That view of increased security risks is backed by 10 of silicon.com's 12-strong CIO Jury IT user panel, along with silicon.com's new Naked CIO columnist.

Peter Pedersen, CTO of Rank Group, said: "I believe the risks will increasingly force IT departments to implement tougher lockdown and device control."

But working from non-office locations is now a fact of life for most businesses and the risks must be mitigated against, according to Nick Masterson-Jones, IT director at Vocalink.

He said: "In response we have brought in a new infrastructure that allows remote access from anywhere but the services all operate within our data centre - the remote access is purely a Citrix window. We can therefore completely control the resources available, including preventing printing, cutting, copying of data and even downloads onto those ubiquitous USB memory sticks."

Ian Auger, IT director for ITN, said backing up employee usage policies with automated enforcement systems can help mitigate the risk.

He said: "We deploy varying levels of remote access from basic Outlook web access to full blown VPN depending on the need. This impacts on the potential risk, ease of accessibility, the amount of support needed to maintain the systems and ultimately the cost."

A lack of training for remote and home working staff is also one of the key risk factors.

Kevin Fitzpatrick, European CIO for Sodexho, said: "Risks increased when we moved away from mainframes and proprietary networks to client devices, but the increased benefits hugely outweigh the downsides. Sensible policies, appropriate security and above all training can sufficiently mitigate."

But others disagree that homeworkers pose a greater security risk than employees in the office.

Nic Evans, European IT director at Key Equipment Finance, said: "With secure VPN and disk encryption there is no reason why technically homeworking should be any less secure than in the office. A few years ago I found tomato ketchup on the keyboard and Chitty Chitty Bang Bang in the DVD drive of a laptop which served as a reminder that you should also have training and strictly enforced usage policies to go with it."

Social networks also pose a security risk, according to Richard Steel, CIO for the London Borough of Newham.

He said: "Increasingly we work in partnerships and share information, and will open up access though social networks - as well as increase home and remote working. Our system's infrastructure designs have to be fit for purpose."
