Some of the different types of network security:
Email Security
Email security helps to secure the data of an email account by blocking incoming malicious content and safely send data outside via the mail channel. Multiple threats such as suspicious links, scams, and phishing can be attached to emails because attackers use elements of personal information or related information in order to appear more legitimate, they can often deceive recipients.
Firewall
Firewalls are secure gate keepers between any source and destination. When it comes to wide network like internet the traffic needs to be protected from any unwanted data been sent or received. Firewalls block or allow the traffic based on the policies/rules configured for incoming and outgoing in addition to inspection of the data packets.
Network Segmentation
Network segmentation is a commonplace of a network security practice for reducing the ease of which network security threats can spread. It even involves classifying a larger network into the multiple sub-networks, with each sub network being managed with its own unique access controls.
Virtual Private Networks (VPN)
Virtual Private Networks (VPN) offers secure remote access from a given endpoint outside the organization into a network. Virtual Private Networks encrypts all network traffic sent from and to the network via a secure tunnel between the endpoint and the network. It is being used by off-site workers that need a secure connection to their company’s network, allowing them to access applications and data that are necessary for their role.
SIEM
Security incident and Event Management, which is also known as SIEM is a security solution which receives all the logs from the security devices in the organization. SIEM product co-relates all the logs and alerts the IT team in case of any abnormal incidents or events. The solution is integrated with threat intelligence as the logs received by SIEM are analysed for any threats.
Web security
Web security software is a type of security which secures the web traffic generated by a user. It limits the traffic generated by authorized employee and protects them from going to any malicious sites where there may be threats or unwanted data.
DLP (Data Loss Prevention)
Data Loss Prevention or DLP is a type of network security that is used by organizations to secure their communication networks. These types of network security can protect sensitive data sent outside the organization domain as each organization have their own critical data which needs to be protected. DLP solutions can prevent the data exposing to bad actors
Behavioural Analytics Tools
IT team should know what a normal set of network behaviour looks like so that they can easily spot breaches or anomalies as they happen, there are multiple tools which will analyse the behaviour of network activities. These tools automatically discern network activities that deviate from the norm. An IT security professional must use these tools to analyse the abnormal behaviours in the network.
Conclusion
To truly protect a network, multiple specialized software and hardware need to be managed and installed. By analysing a layered network security approach with the latest tools that helps to support the principles of the CIA triad, a network can be secured with a wide range of vulnerabilities. Getting the VAPT audit done frequently would help to secure the network more as it closes the loopholes.
