Our company suffered a security breach in the form of a
virus last month. As managing director, I am concerned about the
effect on our business of more serious incidents in the future.
Should I employ a dedicated IT security manager or use third-party
managed services?
Outsource, but someone in-house must retain
control
You are right to take this seriously, because your next breach
could take your business offline and pass the problem on to your
customers and suppliers.
It is tempting to focus on straightforward technology, for example,
installing anti-virus and firewall software, as this appears
affordable and straightforward to set up.
However, securing your business is not a trivial task. You have to
assess your exposure, formulate policies appropriate to your
business and train users. You have to design and implement a
security product and monitor it 24 hours a day, which requires a
detailed knowledge of your network. You have to manage rules for
your firewall and for controlling what people can do on the web.
You also need to produce reports to demonstrate your protection.
This is a tall order for just one person.
In light of this, small and medium-sized organisations are
increasingly turning to managed service providers to help them keep
their businesses secure.
Third parties can help you assess your vulnerabilities and
formulate policies. If they are also the people that provide your
network, they are in a position to fully integrate security. If you
make sure your managed service company has government and
manufacturer accreditation and lays on expert monitoring around the
clock, you are in a position to achieve more peace of mind that a
lone internal resource can provide.
A managed service does not have to be expensive. Third parties can
help you balance your risks and budget and may avoid you having to
make capital investment. When you consider the full cost of
employing a dedicated person, a third-party service may seem very
attractive.
Using a managed service will allow you to concentrate your efforts
on your core business. However, you should still have one person
responsible for security. They need not be dedicated or an expert
in technology, but they do need to understand your company's
business and the impact of security failures.

Consider training the IT manager as security
expert
There is no hard and fast answer. A small company probably does not
need a dedicated IT security manager, but the person who looks
after IT should definitely be keeping a close eye on security. You
could even consider training this person to become a security
expert.
Regardless of whether you have an internal security manager or
whether you employ a managed service provider, the key to IT
security is to implement systems and policies.
However, you should ensure they are not too complicated for people
to use, otherwise you will leave your organisation open to even
more threats as there will be lots of security holes you do not
know about.
If you do decide to work with an external service provider, make
sure they are accredited and can demonstrate their experience in
providing security for a business of your size.

Internal threats can be controlled with
software
Breaches in security can arise from many areas, including internal
staff. The decision of whether or not to employ a security manager
will depend on where the breach has arisen and where you think any
breaches may occur in the future.
Any policy should be explained and accepted by the staff so that
everyone knows what is expected.
Typically, viruses will get into the business through e-mail,
websites or storage media. Protection can be provided against
e-mail-based viruses by using a third party to scan incoming and
outgoing e-mails for viruses.
Similarly, access to the internet can be managed and controlled
using a rules-based web control system.
Next, you need to ensure that you are either controlling or
preventing e-mail and access to the internal systems from computers
that could be vulnerable to viruses. A typical example is where a
user on a home computer is allowed to establish a virtual private
network into the main system but does not have any firewall or
anti-virus protection.
If the previous breaches in security and the perceived threat is of
the nature outlined here, it will be hard to justify a security
manager in a small business.

A security audit will tell you where the problem
lies
When did you last conduct a formal security audit? If a virus can
breach your current defences, this is clearly an indication that
not all is well, but I would not hire anyone until you understand
the extent of the problem.
The British Chambers of Commerce has written an excellent security
guide for small business owners, which can be found at
www.bcentral.co.uk. In it you will find an easy to follow audit
process and an example of a security policy for your
business.
Having conducted the audit you will probably find you need some
external support. Again, you can find qualified businesses at
bCentral.
You should take the opportunity to address your IT systems as a
whole to make sure they are supporting your business effectively;
your security policy should reflect that people will work from
home, client's offices or on the move.
Now you are in a position to choose in-house or third party. I
think you have no choice but to make a member of your staff
responsible for security. However, the tools and services to keep
your systems secure are most cost-effectively provided by third
parties.
It is important to keep all your software updated with the latest
fixes and patches. You should try to purchase software that does
this automatically or make it part of your IT partners' contract.
Finally, in six months' time review the security policy in the
business and in 12 months conduct another audit.
John Coulthard, head of small business, Microsoft UK
Outsourcing would be a suitable short-term
fix
Whether security is managed in-house or outsourced, the first and
most urgent requirement is to perform an audit to identify all
possible risks and to determine the source of the breach.
If anti-virus procedures have been neglected, it is likely that
other areas have been too. The audit should be used to determine a
suitable response and to create a security policy that will
identify clear roles and responsibilities.
The security policy should be communicated to all staff and a
breach of the policy made a dismissal offence. Even if management
is outsourced, someone in the company must be responsible for
enforcing the security policy.
If a dedicated manager is to be employed, they must be of
sufficient calibre and, if resources are limited, the role is
better outsourced. In view of the urgency of the issue, outsourcing
may be the only possible short-term solution.
A third party or in-house manager are both likely to rely on
commercial anti-virus products combined with an appropriate
directory services configuration. In determining whether to
outsource, it is most important to consider who will be responsible
for regular maintenance, identification of new threats, reviewing
the situation and regular reporting.
