While securing the network environment is a high priority for any network administrator, nothing could be farther from the truth. In fact, the IT manager who invests in a complete network security suite will spend well over $3000 in bandwidth in doing so.
Unlike the case with the ‘firewall’ which, in the context of network security, works as a mode of barrier that separates the private networks, from the public network, business network security has to be much more active. The recent attacks on the World Wide Web, on the other hand, have taught us the value of a complete network security suite.
Most business networks are highly susceptible to attack due to the complexity and number of operations in their IT infrastructures. As a result, there has been a rise in the use of software as a tool for network security and risk management.
Thus, as a network administrator, you may need to perform your own assessments of the services and products that you are using. As an organization grows, you may need to incorporate product updates into your schedule. This will have to be done with every security update that you implement.
The upshot is that any corrective action that you take for the network’s security environment must also be reactive rather than proactive. This is because an efficient network will quickly detect an unauthorized access and immediately deny it. A reactive approach may mean that you need to pay for the service of a professional network security provider.
The big question for network administrators is how they can be able to monitor their network’s security systems without employing their own IT staff. Well, it’s not as difficult as you may think.
A firewall, in the context of network security, works as a firewall that separates the private networks, from the public network, business network security has to be much more active. The recent attacks on the World Wide Web, on the other hand, have taught us the value of a complete network security suite.
To start off with, you can use an internal firewall that is typically not connected to the internet. You can install the firewall in its own virtual private network (VPN) or you can connect the firewall to the company’s main network, if you have one. If you use the latter option, then the firewall will look to encrypt traffic that flows between the firewall and the company’s VPN.
In terms of IP addressing, you can assign each network to its own virtual IP address. In addition, you can enable the Internet protocol security protocol (IPSec) on your firewall to help guard the security of the network.
If you’re using Windows servers, then you can use external system security tools that are usually hosted on the company’s servers. In this scenario, the firewall will be responsible for guarding the firewall.
Firewalls can also be integrated with intrusion detection systems, to make sure that the IP addresses that are related to the network have not been used for an unauthorized purpose. But you must be careful when setting up the IP security feature.
Only use external tools that have the same purpose as that of the internal or the company’s system security tools. For example, you don’t want to use intrusion detection systems for the network’s email addresses.
