example, passwords, together with finger
print or retinal scans and personal data,
can be incorporated as an additional
measure. In some instances a phone
factor is used where a message is sent
to a phone to ensure that the correct
individual receives the password.
This can be strengthened further by
authorisation based on least privilege,
intrusion detection and notification and
restrictive access controls – measures
that are of paramount importance
when securing data.
Another way in which data centres
can reduce the risk of rogue insiders
is to eliminate a generic visitor pass.
Although this can seem a low-tech safety
measure, given the research about data
breaches, it is key that safety measures

are equally stringent at the physical
level and not ignored or viewed as less
important. With the unique visitor pass,
all personnel entering the datacentre are
uniquely identified with a photograph,
which is placed on their visitor
badge. This is supplemented with key
information relating to the individual
and their role and the badge is also
time stamped, so the visitor is unable to
reuse the badge at another time, pass
the badge onto someone else or to stay
beyond their permitted time slot.

Conclusion

Data centres must take a multi-level
approach to security, considering both
physical and logical measures. The aim

your fiber

of this approach is to meet compliance
and specific legal requirements as well as
to stay one step ahead of the risk posed
by rogue employees and external threats.
With the right tools in place alongside a
multi-level strategy, data centre
employees will be able to fulfil their daily
tasks, repair and protect systems and
overall satisfy real security needs. While
it is essential that technology continues
to develop and protect against external
threats, it is evident that internal threats
are constantly posing a huge risk to
companies. A multi-level approach
will be able to tackle both, by creating
opportunities to proactively detect, deter
and overcome any data breaches from
an internal or external source.
