The Evolution Of Network Security Technology

In the beginning of the age of online communication, data exchange, data storage and the building of databases, network security technology was rather simplified as compared to what it is today. There was still the need for security and it was no less important then, than it is now.

One of the big reasons that thing were much easier to manage for the experts in network security technology is because of the physical structure of the networks. Since there was no mobile technology every device connected to the system was in the same physical boundaries or the same internal network.

These devices were carefully controlled and monitored and there were updates done on the devices by the IT staff as needed. Additionally, specific programs designed to handle specific security issues within the network and were not designed to operate in conjunction with other programs on the network, nor was it even required.

However, as the networks grew more complex and the number of devices on the network became more mobile and more varied, the need for an evolution in network security became evident. Individual programs and systems that didn't work together created possible and potential gaps in protection. Hackers were able to use those gaps and vulnerabilities to get into systems and gain access to the confidential and secure data and information stored in databases and servers.

Today's Technology

Now, the goal of network security technology is to work synergistically to provide a mesh or a web of security that has limited the gaps and closed up the holes in the security coverage. This is all done even with the use of multiple types of devices that are both private mobile devices and those that belong to the company.

However, not all of the new network security technology is really brand new. Much of the technology has evolved itself, stepping up to address the new types of security issues and helping to protect companies both large and small from the ever increasing risk of hackers and attacks.

With the network security technology used now, individual security options now function together to provide greater control and protection for the network. A good example of this is how Next-Generation firewalls are able to work with Secure Web gateways.

Originally firewalls were simply a pass or not pass type of security measure. Soon they evolved to be able to allow tracking or monitoring of the flow of data between devices on either side of the firewall. This was done through state tables that not only monitored the traffic flow, but made sure the data packets were coming only from the allowed devices. Now deep packet inspection is possible with the Next-generation firewalls to not just track packets but to determine if there are malicious or known attack patterns in the packets moving through the firewall

This technology uses Transport Layer Security, which is the next generation of SSL (Secure Sockets Layer) technology. This is similar to the same technology used with SSL certificates and encryption where there is a recognition of the communication between clients and servers, servers and servers and email sender and recipients using Public Key Infrastructure.

The new firewalls now work in conjunction with secure web gateways. These are more than gatekeepers that prevent access to blacklisted websites, including sites that are suspected or known to have malware. The new generation of secure web gateways actually look for malware, viruses and irregularities that are associated as high risk security issues.

Sharing Information

The new generation of network security technology, which includes other components from the firewalls and secure web gateways, can all exchange information about risks, attacks and security. By sharing this information, there is a more comprehensive and complete level of protection offered across the complete network, helping to reduce the risk of vulnerabilities that hackers are so good at locating and exploiting.

It is possible to include different elements of more traditional as well as next-generation security technology into any network system. This is a more complex task but one that IT professions can use to customize the security based on individual network security concerns or requirements.
