Security

It is imperative that a clearly defined security strategy is at the heart of your business and that your security requirements are designed from the inside out. There is no single magic box to plug in to your network that will solve everything, and it is important you implement the right solution first time.

Securing your network at the core from accidental and deliberate attack is paramount in preventing threats, such as viruses, from having a detrimental effect on your ICT system. It is equally vital that business critical applications operating over your network (in particular voice and multimedia) are fully protected to ensure that you are not a victim to hackers or fraud. Whatever solution or product you chose, you need to know that it will provide the best levels of protection now and in the future. Your security solution needs to have longevity and the ability to evolve with your business as it changes over time.

Network security decisions are based on understanding the inter-relation of the following three factors:

The role of network security is to minimise vulnerabilities and threats in a manner proportionate to the risk. Maximum ROI is seen for solutions that mitigate the highest risks.

Security is built into several component of any proposed solution, to provide multiple layers of defence against deliberate and accidental attack both from outside the network and from within.

Many of the most damaging attacks on networks and applications in recent years have occurred from inside the network:

• Mobile workers connecting un-patched, infected laptops to the network.
• A disgruntled employee deliberately launching an attack against another individual or the organisation as a whole, perhaps through being bribed by a competitor.
• Accidental or deliberate misconfiguration of critical network components.
• The use of unauthorised and insecure applications or devices on the network.
• The unauthorised connection of insecure Wireless Network Access Points to the network.
