Frequently Asked Questions - Security

Why should I be concerned about security?

Any organisation that uses email or has a connection to the Internet is at risk. There are hundreds of thousands of viruses, worms and Trojan Horses circulating around the Internet, many of which will destroy data and even cause permanent damage to servers and workstations. As well as losing data, IT systems that are infected with viruses or worms will often be down for days, sometimes even weeks. In some cases it’s bad enough to put a company out of business permanently.

I have anti-virus software, so presumably I’m safe?

Not at all. There are all sorts of other risks – hackers can break into your network through Internet connections or via Trojan Horses sent via email or downloaded from the Internet. Then of course there are disgruntled employees – perhaps staff who bear a grudge or who have been given their notice; they can cause an enormous amount of damage to an unsecured network. The vast majority of networks – even those not connected to the Internet – are shockingly vulnerable.

Why would hackers be interested in my company?

It used to be the case that hackers would target large systems - typically government, military or large corporate sites. These days hackers are after any unsecured server they can find, so that they can store their programs on it and use it to launch attacks on other networks. And because they use automated tools to scan the Internet for servers which aren’t secured, you are just as likely to be hit as anyone else. During tests, we connected an unsecured server to the Internet to see how long it would take someone to find it. It was probed within sixty seconds.

What would happen if our servers were compromised?

Compromised servers are typically used for launching attacks on other networks. If this happens, the attack would be traced back to your servers and you could be held liable for any damage caused to others. If your mail servers are unsecured, they will be found and used for relaying junk email (known as “spam”) around the Internet. At best this will make you very unpopular and cause your mail server to be blacklisted; at worst this will bring your mail server to its knees and prevent you from sending or receiving your own email. We have seen mail servers used so heavily for relaying spam that the mail server has crashed, and crashed so badly that it wouldn’t boot up again. If you’re infected with a worm, you may have to re-install every server and every workstation from scratch in order to get rid of it.

What can you do for me?

We can carry out security surveys to see how vulnerable your networks and servers are. We then discuss our findings with you, and identify the issues that need to be addressed most urgently. We will then work with you to secure the network and make sure that you are protected against the most common threats. We supply a wide range of security products such as anti-virus software, firewalls and authentication devices to protect your networks and servers.

What if I can’t afford to spend any money on security?

You can’t afford not to. You could lose your data, lose your systems for weeks, lose your reputation – you could lose your entire business if you’re unlucky enough to get hacked or catch a nasty virus or worm. In any case, it doesn’t cost a lot to implement basic security measures which will protect you from the most common threats.
