“One of the
big things that has changed in the past five years is that information has
spread much more widely across the organisation,” says Dave Johnson, business
future manager at Rebus. “That puts the focus on security much more than
before, particularly for people handling subjects like performance appraisal or
recruitment, who have to take great care that the information is kept private

according to security experts, is to install a range of protection devices

identify the source of any potential threat.

accountability, together with a policy on passwords.”

consultants working on short-term contracts are a particular danger, he points
out, since their loyalties may often be to themselves rather than to the

assumption is often that the agency has done that, which is often not the

especially important in large organisations where staff turnover is rapid. “A
company such as Vodafone has a huge number of contract staff working on a

from being a technical specialist to a recruiter, the access I need for that is

other roles as a manager and as an employee. This provides a security layer

Monitor e-mail traffic

unsolicited messages, and pornography, as well as the means of disseminating
sensitive commercial information, personal details about staff or customers, or
even libel about other companies.

In one case
an employee admitted to serious shortcomings within the company in a private

individual sent an e-mail with extreme religious content to everyone in the
company, provoking a flood of responses that blocked the system.
that goes largely unrecognised is that e-mail serves as evidence of an exchange
of promises, amounting to a contract. A disaffected outgoing member of staff
can abuse that, for instance by ordering a lorryload of pencils that the
company would be liable for.
Protect employee information

increasing danger both for individuals and organisations, which are liable
under the Data Protection Act for misuse resulting from leaks.
there has been little regulation of the Internet traffic in CVs but this could
Jennings, managing director of job site GraduateBase.com, says it will not send
CVs on-line without providing an audit trail. That enables job seekers to know
exactly to whom the information is going and to receive an assurance that it
will be deleted once used, as will soon be required by EU law.
“HR has to
be very careful about sending a CV to other companies, because they don’t know
where it is going to end up,” he says. “This applies particularly in the case
of individuals who are already in work: you can imagine what would happen if
someone’s CV ended up on their bosses desk.”
