This is the second article in the series of “Network Security Explained” which lists out different types of network security and their significance.
In the current year, 2019, the global cybercrime is expected to rise by $2.1 trillion, which shows how crucial the security of an organizational network is. Network security ensures the security of organizational IT assets, including data and online network traffic. Networks are likely targeted by an array of threats that are aimed to intrude and destroy the network components fully or partially. Limiting access to the network can be managed by having an effective network security strategy.
Network security stands for the integration of multiple layers of defenses in the network, and each layer has defined policies and controls laid out. The network access is also defined to authorized users. Malicious users are blocked from intruding into the network infrastructure. The world is transforming by digitization, and this has greatly impacted our daily lifestyle. We are dependent on the internet for most of our regular activities. Digital vendors should be protecting their networks and devices while delivering the services demanded by employees and customers. With increasing cyberattacks every day, the need to implement network security becomes important.
|S. No.||Types of Network Security||Protects from||How it Helps|
|1||Antivirus and antimalware||Malware like spyware, ransomware, Trojans, viruses, and worms||The software scans for malware entry and regularly tracks files to detect anomalies, fix and repair them.|
|2||Application security||Vulnerabilities and bugs||Finds vulnerabilities and bugs to fix them so that attackers can not exploit them.|
|3||Behavioral analytics||Online attacks on app or website||Behavioral analytic tools differentiate between normal and abnormal behavior and alert the security team.|
|4||Email security||Phishing like Social engineering||Email security application blocks incoming malicious emails and scans outbound messages to protect the loss of sensitive data.|
|5||Firewalls||Attacks from untrusted outside networks, like the internet||Firewall can be software or hardware. It manages traffic and secures all connections when online.|
|6||Intrusion prevention||Network traffic||Intrusion Prevention System (IPS) setting interface allows admin to configure the ruleset updates for Snort (an open-source, free and lightweight network intrusion detection system (NIDS) software).|
|7||Mobile device security||Mobile accessed through the official network||Control on the usage of the official network, configure connections to keep the network traffic secure.|
|8||Security Information and Event Management (SIEM)||Threats goes unidentified||SIEM products provide all the information needed by security staff to identify and respond to threats.|
|9||Wireless security||Malware or vulnerabilities makes way for intruders||Stringent wireless security along with the installation of wireless LAN, will prevent intrusions.|
|10||Network segmentation||Unauthorized access||Segmentation defines the right to access based on location, role, and more so that authorized access can be shared.|
|11||Virtual Private Network (VPN)||Unauthorized access to a network||Encrypting the connection from an endpoint to a network, over the internet.|
|12||Web security||Malware by accessing malicious websites||Web security restricts access to malicious websites.|
|13||Network Access Control||Malicious content, unauthorized access||Helps in controlling access to the network. Every device must be recognized to access the network, and non-compliant devices receive limited access or blocked.|
|14||Endpoint security||Network connectivity via remote devices spread vulnerabilities||Endpoint security methodology protects the network from known and unknown threats.|
The rising cyberattacks call for a need to understand the importance of network security by all the organizations irrespective of government, small-scale, multi-national, startup, or organizations that are based on service motive. Network security should hold the same level of significance among them. An incident would result in substantial irreparable loss, whereas a secured network can protect the IT infrastructure and information from getting compromised by the intruders. In our upcoming article from this series, ‘Network Security Explained’ we shall be discussing how finding the right network security tools for businesses and how this will impact businesses and consumers.
