Entac - IT and Network Security

Virtualisation

Over the past few years, virtualisation has become one of the major trends in IT. Whilst virtualisation provides a number of benefits for businesses - such as reductions in power consumption, server consolidation, and maximisation of resource availability and utilisation - virtualisation also brings with it a number of security challenges.

Entac can assist in the development of innovative security solutions for virtualised environments to ensure that your business can take advantage of the benefits of virtualisation whilst remaining secure and compliant.

Security Solutions

Virtualised systems are challenging environments to secure. Innovations such as distributed switch fabric within the hypervisor have made aspects of network security such as traffic inspection and network segmentation extremely challenging as the path traffic takes through the virtualised network is more uncertain.

Additional concerns such as securing virtualised applications and desktops without overloading physical resources are difficult to deal with and require careful design and implementation to be sure of success. Entac can assist in the design, selection, and implementation for your virtualised environment.

Fabric Design

As more networking functions migrate to the hypervisor and become virtualised themselves, vendors have begun to refer to the combined virtual and physical networking estate as the network fabric. The migration of aspects of the fabric into the hypervisor has led to a number of security challenges, particularly with regard to segmentation and inspection of traffic that traverses within a single physical or distributed hypervisor.

Entac understands the challenges of securing the network fabric within virtualised environments, and our consultants have a track record of developing intelligent strategic solutions to provide unparalleled security and visiblity within and throughout the network fabric.

Service Availability

A major factor in the widespread adoption of virtualisation technology has been the ability of consolidated distributed hypervisors to provide high availability for critical applications and services. This has led to massive improvements for internal service availability, but all too often, these internal improvements have not been matched with a coherent network availability architecture to ensure bandwidth is available to service the more efficient application back-ends.

This has led to the network architecture falling behind the service layer design as resources are dieverted from networking hardware to the drive for virtualisation. Entac consultants can help harmonise the strategic service and network layer designs to ensure that the network does not become the weak point in your systems architecture.
