Computer Network Security

Everyday, Internet is being affected by software securities vulnerabilities, worms and new viruses. The network security of the system has become a management activity which needs ongoing network monitoring on continuous basis. For tackling these daily security hazards, CSC (Computer Services Centre) is constantly working to enhance the security management devices by launching advance technologies to protect network security system. Moreover, CSC is not only working to protect the threats originated from internet but also from the internal threats generated by the user of the system.

Types of Network Security Devices

Here are some of the network security devices which can help you protect your system from internal and external threats:

• Firewall and Internet Router

Firewall and Internet Router has the ability to implement network policy and authorize only allowed protocol/traffic with the approved IP address range to pass through. These policies can be rather packet examination and static which is performed by specific hardware devices. Network security devices help in filtering the data to an appropriate way so that the system stays safe and protected by any generated threats. They provide fast filtering mechanism which discards all those packets which tends to violate network policy.

• (IPS) Intrusion Protection System

There are some network packets which pass through firewall and still contain virus which have the ability to harm the system. For example, entire email traffic should be permitted to go through firewall specified in the firewall policy. Keeping this in mind, IPS offers second level of the network packet examination of normalized traffic patterns and attack signatures. Basically, IPS works like “Anti-Virus” software such as MacAfee Inc and Computer Network Security Software Inc working in the network appliance scrutinizes network packets at the level of Multi-gigabit in network security system.

• Traffic Shaping Device

The traffic shaping device is specifically designed to help us in making fair allocations. This device has the ability to automatically to learn and classify the flowing of network traffic. In addition to permitting and blocking network packets, it also has the capability to shape, increase and provide the guaranteed bandwidth for pre-defined applications.

It is quite necessary to keep your system safe from all the threats roaming around on the internet to harm you. By using the above network security devices, you will able to track all the undesired threats packets efficiently.
