Types of Network Security

There are several types of network security. These may be categorized into physical security, software, and technical security.

Physical Security – This is the most common type of network security.

This involves the physical measures and systems that a company employs to ensure that its servers and computers are safe from being attacked by intruders. Some examples of physical security include firewalls, electronic locks, industrial strength printers, GPS tracking systems, and locks on door cabinets.

Software – This is the most complex form of network security. Companies that employ this type of use network security software to protect the data and computer systems within the company.

Technical Security – This type of network security is closely related to software. The basic idea behind this type of network security is that it provides a foundation for the various types of data that will be used in the network. It also relies on the use of separate encryption methods for each category of data that will be used within the network.

The underlying concept of all types of network security is the protection of data. The network security measures that a company employs have to address the protection of the company’s confidential data as well as data that are either not very confidential or will not be protected at all.

A firewall is the most obvious way of protecting a business from intruders or those that are trying to steal your company’s confidential information through physical security. A firewall provides a boundary that allows only authorized people access to sensitive files and information that belong to the company. It should be considered an essential part of any physical security.

Another important aspect of network security is access control.

Access control dictates the level of access given to employees or system administrators in the office. All employees should be allowed limited access to the office network while system administrators should be able to grant users access to the network if required.

User authentication and authorization are equally important because this establishes the company’s security. This ensures that only authorized people can gain access to data. It also protects the computer from any malicious acts.

Physical security will come into play when an employee is about to access or copy sensitive data on his computer. Therefore, he must first get permission from his supervisor. Physical security includes making sure that nobody will be able to open the door or other physical barriers of the office that can prevent employees from accessing the data.

If there is no control of computer systems within the office, it is possible that the employees could be vulnerable to hackers or worse. Physical security would not be a problem if there are some means of securing data while data is transferred.

The number of different types of physical security is not the only thing that should be considered when it comes to protecting sensitive data.

  • It also needs to be decided how the information will be secured from external sources, such as telecommunications.
  • It is important to consider both security and convenience when it comes to network security.
  • There is no need to compromise on these things, but it is important to consider that a certain amount of work should be done in order to secure the office.
