Network Security

Secure networking ensures that the network is available to perform its allotted task by defending it from attacks originating inside and outside the organization.   Conventional thinking associates this to a handful of precise requirements, including user authentication, user device protection and point solutions. However, the move to junction, together with better workforce mobility, rendering networks to new exposure, as any connected user can prospectively attack the network. Application traffic must be securely transported across the network, keeping away from threats such as theft of intellectual property or private data. In addition, the fundamental infrastructure must be secluded against service disturbance (in which the network is not available for its planned use) and service theft (in which an unauthorized user accesses network bandwidth or an authorized user accesses unauthorized services). While most organizations have a focal point on protecting the application traffic, few put adequate infrastructure focus beyond point solutions such as firewalls. To protect the whole network, security must be integrated in all layers and the inclusive networking lifecycle.
Secure networking rivets securing the application traffic as it navigates the network. It should cover these areas:
  * Perimeter Security: protects the network applications from outside attack, through technologies such as firewall and intrusion recognition (Warren, How to - UK Enterprise & Technology IT How To articles & advice from IT Experts).
  * Communications Security: provides data discretion, integrity and non-repudiation, normally through the use of Secure Sockets Layer or IPsec virtual private networks (VPN).
  * Secure Networking: expands this by defending the essential infrastructure from attack.
  * Platform Security: ensures that each device is accessible to execute its intended task and doesn’t become the network’s single point of failure. The network security plan should... [continues]
