Computer Security

Computer security requires a wide range of technically-trained experts who understand how computers work and networks function. A secure computer network also requires its users to be well-informed in the company’s security policies and how to operate strictly within the procedure whilst remaining watchful for situations that may cause or lead to a potential threat to the network.

For more information see IT Security and Information Security.
How Can Computer Network Security be breached?

Below are 5 broad areas of security breaches together with some of the questions you might want to see answered:

• Viruses (e.g. How do I recover from a virus attack?)
• Inappropriate Usage (Can I prevent inappropriate usage of my company's data?)
• Unauthorised Access (What risk do I face from hackers?)
• Theft (How do I safeguard my company's assets?)
• Systems Failure (How to cope with a major failure).

Your IT Network Security

Linking private networks to the Internet has become essential especially for emailing which is now one of the main line of communication. As a result your entire network become exposed to attacks from various levels of hackers, viruses and spy ware. Once a hacker gains access to your network he can use your computers to attack other companies, erase and crash systems just for the fun. To combat this unauthorised access into your network, it takes more knowledge and experience than most people realise.

The designing of internet linked networks and protecting their functionality is no simple task. Anyone can buy a small network hub and put together a very user friendly private network but protecting it from unwanted external sources is far from simple, rather it is a highly specialised and complex job.

When designing a network environment you must plan for any future growth and demands that may be placed on it coupled with a comprehensive security policy. Without a carefully designed network, a poor performance and a progressive slow down in business operations will eventually occur costing your company thousands of pounds.

How can GNS help you Secure your computer network?

GNS can help you build an underlying computer network infrastructure, policies adopted by the network administrator to protect the network and the network-accessible resources from unauthorised access and the effectiveness (or lack) of these measures combined together.

In Addition GNS can employ hardware and software firewalls to enforce access policies such as what services are allowed to be accessed by the network users and prevent unauthorised access to block potentially harmful contents such as computer worms being transmitted over the network.

We can also help you to setup an intrusion prevention system (IPS) to detect and prevent such malware and monitors for suspicious network traffic that tries to attack your contents by enforcing ‘denial of service’. Communication between multiple hosts using the network could be encrypted to maintain privacy.
