Do you know what network security is?
Network security can be defined as the process of ensuring that communication between devices is secure, and there are different kinds of security for different kinds of devices.
A company’s network consists of computers, servers, routers, hubs, switches, bridges, networks, firewalls, and more. This means that each computer has its own security policy, and the company must create a policy for each device that they own. The policies will ensure that communication among devices is secure.
There are two types of security for network devices: passive and active.
There are also several different security levels, such as client/server, wireless, and encrypted.
The first thing to do when setting up a security policy is to determine what type of security system will work best. There are many different options to choose from, and the best way to decide which option is best for your organization is to research what they have to offer.
For example, a client/server model allows users to access resources over a network but does not encrypt the data. On the other hand, an encrypted client/server model does encrypt the data, but clients still cannot access the data. In this case, the user must enter an encryption key before the data can be accessed.
Another option is the wireless model. Wireless models use an encryption protocol called WEP or WPA to encrypt the data between clients and servers. The encryption is strong enough to be considered secured.
At the same time, wireless models also do not provide any protection for the data. It is also important to use a firewall to protect the information from unauthorized access. Other choices include deploying a wireless access point and software that support wireless client access.
In the same way, the decision for data security is the same. Active (software-based) or passive (hardware-based) firewalls are the two most common.
The last thing to think about when implementing network security is where the network is located. A single point of failure is very dangerous for any kind of network, but it is especially risky if the network is located in a building. This is because a physical break-in of a single network device may compromise the entire network.
While active firewalls are very effective at keeping out intruders, they have a limited ability to stop attacks from outside the firewall. In this case, a firewall that is configured in such a way that it only blocks connections to external networks is better.
Information about the security of a building can be found online through many security monitoring programs. These programs keep a record of network activities and issues and can alert management when network activity becomes risky.
Before securing a network, one should first ask if their company needs to use network security. Doing so can help businesses improve the overall performance of their network.
