The essential elements of network security

Business networks run on a foundation of switches and routers. Switches tie together devices like computers, printers, and servers, while routers connect your networked computers to the internet. This allows better data sharing throughout the organization, which in turn helps in improved communication and work efficiency.

But beware, if you are connected to the internet, then your entire network is vulnerable to several threats. Your business data becomes susceptible to malicious programs like viruses, spyware, adware, Trojan horses, worms, phishing, and other malware. When you least expect it, cybercriminals can slip into your system and exploit vulnerabilities such as unsecured wireless networks and even weak passwords, just to name a few. The stolen data can then be held for ransom, used in identity theft, or even launched to attack other computers. This is why having proper network security is vital.

What is network security?

Network security is designed to protect the integrity, confidentiality, and accessibility of computer networks and data using software and hardware technologies. An effective network security system is multilayered to provide more reliability. It should be able to detect unusual network activity, and catch and prevent internal and external threats from reaching the network.

To best protect your business, start with the four essential elements of robust business network security.

1. Network access control (NAC)

A NAC system allows organizations to control and restrict who and which devices can access network resources. It blocks or provides limited access to noncompliant devices.

2. Firewall security

A firewall acts as a barrier between your trusted internal network and untrusted external networks like the internet. It filters incoming and outgoing network traffic based on the configurations that you have set. It can be software running on your laptop or dedicated hardware in a corporate network.

3. Intrusion prevention system (IPS)

An IPS identifies, records, reports, and blocks vulnerability exploits from occurring over a network. It is located behind the firewall and serves as a complementary filter of such suspicious activities.

4. Security information and event management (SIEM)

A SIEM system deploys multiple collection agents to gather security-related events from end-user devices and servers, as well as firewalls and IPS. It identifies deviations and sends out alerts and deploys security controls if it finds potential security issues.
