Network security: The different types of network protection

Types of network security protections

Thankfully, there are a range of network security protections available these days. However, as hackers devise more sophisticated breach techniques, all options need to be regularly tested and updated with the latest versions to stay on top of emerging threats.

• Firewalls

A network’s first line of defence, firewalls are set to monitor potential incoming threats and are measured against a set of rules established by network administrators. Think of a firewall like a bouncer for your network. 

• Email security

Deemed as being the most common network security threat, email security applications essentially work to block any incoming threats. These threats most frequently appear in the form of links, which if clicked, download malware, or ignite a phishing attack.

• Data loss prevention (DLP)
  

If you’ve ever found yourself unable to upload, download, forward or share a file while working within an organisation, this could be data loss prevention technology (DLP) in action. DLP intentionally disables individuals from being able to share information, particularly if it is classified, with anyone outside of the network.

• Behavioural analytics
  

Network administrators use analytics tools to gain a picture of how users typically behave within the system. These tools also enable any unusual activity to be identified, as it could be the beginnings of a possible security threat. By identifying unusual behaviour early on, administrators are able to mitigate issues before they become a larger threat.

• Application security
  

Every time a new application or third-party system is integrated into a network, it is vital that it is vetted to avoid the possibility of infiltration from another unknown and potentially unlawful network. This vetting process is the essential aspect of application security. 

• Antivirus and anti-malware software

You’re likely familiar with some of the anti-virus and anti-malware software on the market. The role they play in network security is to continuously scan and monitor the network it is installed in, spotting any suspicious activity. This in turn adds a level of protection against potential cyber threats.

• Access control
  

While many users may need to be able to access a network, not everyone will need the same level of access. Users need to be classified into groups, with each having predetermined levels of access to relevant sections of the network. This will apply to the individual user, as well as to the devices connected to the network.

• Cloud network security 

Increased efficiencies and productivity are the drawcard for businesses moving to the cloud, but this shift also presents data risks. Cloud computing security needs to be integrated and often includes encryption-based measures.
