A network infrastructure consists of hardware and software resources that work together to manage the enterprise network. The network provides communications and services between users, applications and processes.

These are a few elements that exist in an infrastructure network:


  • Routers
  • Switches
  • LAN cards
  • Cables


  • Operating systems
  • Firewalls
  • Network security applications

Network services

  • T-1 line
  • Internet connection
  • Wireless protocols
  • Satellite
  • IP addressing

You have to adhere to these aspects below to ensure that your infrastructure is running optimally:

Create a critical infrastructure list: There are a number of ways to create this list. You can do a walkabout and document all the hardware you have and install software to scan your network. When you’re manually checking your network, start at the core switch and analyse what’s connected. This list will consist of routers, firewalls, distribution switches and any devices used to keep your network operational.

Implement a change control process: It’s too easy to duplicate change control processes from previous jobs. Don’t do this. For every system on your critical infrastructure list, create its own log of changes and who implemented them.

Keep dependencies in mind: Certain systems will ultimately be dependent on others. This makes monitoring tools a priority for the health of your network. In fact, it’s advisable to have a dedicated team monitoring your network.

Ensure you have the optimal data: Make sure you have enough space to house your data. Besides this, back up your network and have a contingency plan such as a disaster recovery service in place.

Set up security standards: The most important asset to keep in check will be your users because they are the weakest link in any security plan. Before a user gains access to a network account, they require training on what to do and what not to do. Make sure each user obtains an account dedicated only to them.

Policies should be created to help secure your network such as an Internet access policy, remote access policy, network security policy and remote access policy. Policies can then be used as the ultimate reference point when making important security decisions.

Keep an eye on network traffic: Don’t simply rely on your firewall to protect your network, you need to analyse your traffic flow. Achieve this through the use of an intrusion detection system.

Digital disruption is creating a shift in the way organisations run their networks. According to Dimension Data, a proud strategic partner of IS: “We’ll also see more businesses exploiting software-defined networking and network virtualisation across the network in the data centre, hybrid WAN and the campus, as part of their efforts to transform their networks.” It is clear that the industry is leaning towards a hybrid IT approach, which includes a move away from technology integration towards services integration.
