In layman’s language, Network security is your first line of defense against ever-increasing cybercrime.
Network security refers to the tools, tactics, and policies that are used to monitor, prevent, and respond to unauthorized network intrusions, as well as to protect digital assets such as network traffic.

What is Network Security?
Network security refers to the various policies and techniques that limit unauthorized access to and misuse of the computer network and its resources. It also monitors network changes or delays. Network security also guards against hacking and unauthorized changes to networking systems.
Network security is made up of hardware and software technologies (as well as resources like knowledgeable security analysts, hunters, and incident responders) and is designed to respond to a wide range of potential threats to your network.
What are the benefits of Network Security?
There are network security tools and resources available to help the company protect its confidential data as well as its overall efficiency, credibility, and even business capacity. Here are some of the most important benefits of network security.
Data Security:
Network security guards against unauthorized network access. Many sensitive details, such as customer personal information, are stored on a network. Such sensitive data can be jeopardized if someone hacks into the network. As a result, network security should be implemented to safeguard them.
Prevents Cyber Threats:
The internet is where the majority of network threats originate. Hackers are experts at hacking new internet threats and malware. If your network security is lax, the flow of network information over the internet may be hampered. Network security tools can aid in the security of systems and networks.
Centrally Controlled:
Network security software, as opposed to desktop security software, is managed by a centralized user known as a network administrator. Whereas the former is vulnerable to viral attacks, the latter, because it is built on an internet-free system and is controlled by a single person, can prevent hackers from causing any harm to the network.

Aircrack
Aircrack is a collection of WEP and WPA cracking tools that provide ideal solutions for mobile device internet security. Aircrack is a reliable piece of algorithm cracking software. Airdecap for WEP/WPA file decryption and airplay for packet injection are also included in the suite. This suite includes a slew of other tools that work together to form a robust collection of Information Security applications. Aircrack is a one-stop shop for all wireless security needs.
Snort
It is a free and open-source intrusion detection system that supports all operating systems and hardware. The software examines protocols, searches and assembles content, and detects various network security threats. Snort is an effective intrusion detection and prevention framework due to its simple setup, versatile rules, and raw packet analysis.
Access control
The amount of damage threat actors can cause is severely limited if they are unable to gain access to your network. However, keep in mind that, in addition to preventing unauthorized access, even authorized users can pose a threat. Access control allows you to increase network security by restricting user access and resources to only the parts of the network that are directly relevant to individual users’ responsibilities.

Malware removal software
Malware is software that is designed to infiltrate computer systems and networks. It can take the form of viruses, trojans, worms, keyloggers, spyware, and other malicious programs. Anti-malware tools are a type of network security software that detects and prevents malicious programs from spreading.
Email safety
Email security, like DLP, is concerned with security flaws caused by humans. Attackers use phishing strategies to convince email recipients to share sensitive information via desktop or mobile device, or to unintentionally download malware into the targeted network. Email security can be used to detect potentially dangerous emails and to prevent attacks and the sharing of sensitive data.

Endpoint protection
Bring your own device (BYOD) is becoming increasingly popular in the business world, to the point where personal and business computer devices are nearly identical. Unfortunately, users who connect to business networks via personal devices can become targets. Endpoint security provides an extra layer of protection between remote devices and business networks.
Cain and Abel
Cain and Abel is a password recovery program that only works with Windows. It can record VoIP calls, decipher encrypted passwords, and examine routing protocols. Cached passwords, password boxes, crypts, brute-force cryptanalysis, and other features are revealed.
Argus
It is one of the most powerful free and open-source network analysis tools available. Argus is an abbreviation for Audit Record Generation and Utilization System. The software, as the abbreviation implies, performs effective, in-depth network data analysis with quick, detailed reporting across large networks.
Virtual private network (VPN)
VPN security tools are used to authenticate communication over a virtual private network between secure networks and endpoint devices (VPN). For authentication, remote-access VPNs typically use IPsec or Secure Sockets Layer (SSL), resulting in an encrypted line that prevents third-party eavesdropping.
Web Security
Web security is a catch-all term for network security measures implemented by businesses to ensure safe web access when connected to an internal network. It consists of security tools, hardware, policies, and other components. This prevents web-based threats from using browsers as network entry points.

Conclusion
Everything that can affect a company’s networks and everything that can help prevent those attacks is defined as effective network security. Network security tools are designed to assist all organizations in implementing intelligent policies and processes to safeguard data, networks, and systems. Staying current on global threats and ensuring networks are secure from individual hackers to larger coordinated breaching efforts are also part of network security.
