Dual network cards allow a computer to connect to two independent networks, increasing productivity. However, there are security vulnerabilities, such as the potential for virus propagation and compromised data. Dual network cards can be useful for software developers and training, but may require advanced configuration and can be problematic for inexperienced users. Companies with secret data should avoid using dual network cards.
Many computers today are capable of supporting dual network cards. There are several pros and cons to using this type of technology. The main advantage of two network cards is the ability to connect to two completely independent networks at the same time. This can increase productivity because one machine can work in two separate environments. The downside is potential security vulnerabilities that occur through sharing networks on a computer.
A computer with two network cards can connect to multiple computers. Most software developers require access to both a development environment and a separate test environment. Having two network connections allows the developer to access both networks through one computer. Without this feature, the developer is forced to use separate computers for each task.
Most large companies use training software to help employees learn the computer applications used by the company. These applications are typically run on a separate training network. A computer with two network adapters can access both the training and production networks. This setup saves organizations money because the employee can use one computer for both training and production.
One of the main problems with dual network cards is security. A computer with two network cards can be used as a virus propagation device. If a hacker gets into a computer with two cards, he can send malicious software across multiple networks.
If a computer is connected to both a production network and a test network, production data can easily be compromised. This is because the production data will reside on a computer connected to a test network. If the user accidentally sends this data over the test network, it can be seen by users who shouldn’t have access to it.
A company that requires covert network environments will not allow two network cards on a single computer. This is considered a security breach due to the vulnerability of data exposure and cyberspace infiltration issues. Companies with secret proprietary data should refrain from using two network cards.
Some companies use dual network adapters as a way to manage overall network performance. With this configuration, one network will be connected to a slower capacity server with the other network connected to a high bandwidth capacity infrastructure. Computer applications can be configured to run on the appropriate network infrastructure.
Using two network cards can be problematic for most inexperienced computer users. These network devices may have configuration problems when you restart your computer. Since the dual network approach is usually an advanced configuration, it is not a default configuration for most operating systems.
