The common types of network security are:

• Antivirus and Antimalware Software
• Application Security
• Behavioral Analytics
• Data Loss Prevention (DLP)
• Email Security
• Firewalls
• Mobile Device Security
• Network Segmentation
• Security Information and Event Management (SIEM)
• Virtual Private Network (VPN)
• Web Security
• Wireless Security
• Endpoint Security
• Network Access Control (NAC)

Network security helps you protect your proprietary information from cyber attacks. It allows you to take preventative measures to secure your organization’s networking infrastructure from unauthorized access, misuse, malfunction, modification, destruction or improper disclosure. By implementing network security measures, your users, computers, devices, and programs can perform their authorized critical functions within a secured environment.

Security analytics is a cybersecurity approach that aims to take proactive security measures based on the analysis of data. Incredible amounts of data keep passing through your network continuously. In such scenarios, your security appliances like firewalls or Intrusion Detection Systems get only limited time to inspect the traffic flowing through your network. This is where network security analytics can help you.

Network security analytics broadly comprises the tools, technologies, and methodologies that make use of data science techniques such as statistical analysis and pattern detection for network security risk management.

Intrusion Prevention System (IPS) is a kind of network security that continuously monitors your network to detect and prevent identified threats. An IPS system captures information on any malicious incidents and reports the events to system administrators who can take preventive actions to defend any cyber attacks. IPS is placed in between the direct communication path between the source and destination so that it can actively analyze and take automated actions on the traffic flowing through the network.

VPN or Virtual Private Network extends a private network across a public network. It allows you to create a virtual private network from a public internet connection by masking your internet protocol so that your online activities are virtually untraceable. VPN protects your online activities such as shopping, emails, bills, and payment transactions using encryption and anonymity, and makes your web surfing anonymous.

Network segmentation is intended to improve network performance and security. It works by dividing or segmenting a computer network into smaller parts so that an organization can control how traffic flows across each part of your network. You can restrict or define the traffic flow based on the traffic type, source, destination, and other criteria. Segmentation reduces network congestion, restricts the damage caused by cyberattacks, protects vulnerable devices, and minimizes the costs associated with regulatory compliance.
