A protocol or system designed to protect a network and data against any unauthorized access and to secure the network is the Network Security system. An effective network security system ensures secure access to authorized personnel or systems only. Meanwhile securing both hardware and software and warding threats off and also preventing their access to your network.
Network security is designed as a multi-layered system that includes mainly two processes: authentication and authorization which implement policies and controls that allow authorized users while denying malicious elements or threats.
Today’s world is a digital one and wherever we go there is some sort of a device, connected to a network, making our lives easier but itself is always at stake owing to several kinds of threats like hacking, malware like spyware, ransomware, phishing, etc.
For every organization, it’s a must to have a proper network security system to safeguard its data and proprietary information from attacks because letting that happen would destroy the company’s goodwill and reputation. To keep potential threats at bay the system needs to recognize the users and devices. Through network access control (NAC) noncompliant users may be avoided or given restricted access.
Several kinds of malware infect a network but lie dormant for some time. The use of strong antivirus or antimalware is also advisable not only to block them upon entry but also to track the anomalies created by them, to remove the malware and fix the damages. Any applications used by a company may have some vulnerability that may be used by the attackers to infiltrate your network. Hence, Application security is needed to remove those vulnerabilities and to secure the hardware, software and your reputation.
A good security team knows how to differentiate between normal and abnormal behavior and hence, can identify and negate any potential threat. It includes installing firewalls, intrusion prevention systems (IPS), network segmentation to classify network traffic and assign access rights based on IP addresses, role, location, etc., and also containment of suspicious devices. Security information and event management (SIEM) collect information through physical and virtual appliances and server software to aid your security staff in identifying and responding to threats.
Creating a Virtual private network (VPN) is also a tool used by network security teams to encrypt and secure a network whereas web security is another important tool to safeguard a company’s website while restricting access to malicious websites and protecting the web gateway as well. Another addition that a network security team needs is wireless security because a wireless LAN could always be vulnerable to exploitation.
If network security is such an important thing, then it’s a must to have a good network security team like PRONIX to ensure security and cost-effectiveness. Not only their experienced and well-trained team has a good in-depth knowledge of the components but also about the threats and how to secure the system against them. A team like that from PRONIX would always be dependable.
