The Importance of Network Security

in Network

With intrusion techniques getting more sophisticated by the day, Network Security has become a hot topic of discussion. Long gone are the days when businesses were able to operate with an unprotected network.

Exploitation of computer networks is becoming more common and it's absolutely vital for small businesses to be able to protect their privacy from serious threats that would try to steal their information.

Many believe that employing a hardware router or a software firewall is the only step required in securing the network, but the truth is that these methods are only the first step to ensuring that your network is 100 percent secured.

In order to be sure that your network is completely defended from intruders, your network security should employ more than the traditional router and firewall setup. So that you can understand how involved network security should be, you first need to be familiar with a few of the terms related Network Access Control (NAC), the approach by which access to a computer network is determined.

Authentication, enforcement, endpoint security, and management are the four core components of NAC and their strength determines how well protected the information on your business network is.

  • Authentication – This is the shortened way of referring to comprehensive authentication protocol. These are the protocols that determine external threats to the network by verifying what should and shouldn't have access to it. Firewalls handle many authentication needs but they alone can't completely prevent snooping of unencrypted messages.
  • Enforcement – The second layer of defense behind authentication. While basic security assumes that an authenticated client never becomes a security threat, enforcement ensures that this doesn't happen.
  • Endpoint Network Security – This NAC strategy focuses on security at the individual end-user level, while also being centrally managed. Personal firewalls and anti-virus programs on individual workstations are examples of endpoint security.  
  • Network Management – As what is perhaps the most important level of network security, network management  ties together the other components and tailors everything to the needs of the client business while. The term also applies to the constant monitoring of network activity

With all of these aspects of network security being deployed, businesses are better able to protect themselves from the biggest threats to their networks. Namely, threats like:

  • Viruses – Programs that compromise the network and spread until the network is rendered useless
  • Trojan Horses – Malware disguised as something that is welcome on your network. Once uncovered, it works similarly to a virus to steal information.
  • Spam – Unsolicited messages sent in bulk that than lead to cases of fraud and extra cost associated with acquiring more space to receive messages.
  • Phishing – An attempt to steal information such as usernames and passwords through the use of deception via email.
  • Packet Sniffers – Programs that intercept data sent over networks and decode the data in attempts to recover sensitive information.

With business being conducted over computer networks in such high volumes, the chances of coming under attack by the known dangers to network security increase greatly. Whether a business is a Fortune 500 conglomerate or a small local company, the vulnerability exists and steps should be taken to protect sensitive information.
