What’s New in the Network Security Course from InfosecTrain?

Many aspects of our lives have migrated to the digital realm. We can find anything from birth dates, social security numbers (or other identification numbers), health history, credit history, bank accounts, utility bills, and other information on the internet. We use the internet for money transfers, communication with family, friends, and coworkers, shopping, entertainment, and research. All of those activities and transactions are accessible to threat actors. We are more likely to be attacked the more time we spend online.

Due to the reliance on various business and personal communication verticals, businesses of all sizes and objectives must secure their networks with appropriate digital security and compliance strategies and risk mitigation procedures. Even though no network is completely safe from cyber threats, an effective and dependable Network Security system can ensure the network’s critical security.

What is Network Security?

Network Security is the first line of defense that protects networking infrastructure from data breaches, unauthorized access, and manipulation. Network security incorporates a wide range of techniques, systems, and processes. It alludes to a collection of guidelines and configurations created to safeguard the integrity, confidentiality, and accessibility of data and system networks.

This article covers the major distinctions between InfosecTrain’s new and old network security courses.

An Overview of Network Security Course from InfosecTrain

In response to COVID-19, organizations have enabled flexible working practices for employees by encouraging a culture of working from home. As a result, attackers see an opportunity to exploit the weaknesses and take advantage of the human factor. We can see that mobile devices now generate more than 55% of internet traffic. This necessitates that networks handle and safeguard mobile traffic in novel ways and adhere to new trends. 56% of all Internet traffic derives from automated sources such as bots, hacking operations, spammers, and individuals posing as someone else. And approximately 4,000 ransomware attacks occur daily.

So, keeping network security in mind, InfosecTrain introduced a customized course in Network Security. Earlier, this course helped candidates understand the fundamentals of networks and their various components like firewalls, routers, different types of network attacks, fundamentals of browser history, and cryptography basics. Here, you can check out more about the Network Security course from infosecTrain.

Moving from these basic network security concepts, InfosecTrain moves a step ahead with a new, updated network security course. Here are some new topics added to this course.

1. TCP/IP networking basics and TCP/IP protocol stacks are various networking aspects.
2. Concepts of basic operating systems, security fundamentals, and different types of network attacks.
3. Introduction of attacks in an enterprise environment, like reconnaissance attacks, network access attacks, denial of service (DoS) attacks (hands-on using script), and many more.
4. The concept of network security policy, protocols, and controls, network security appliances, network protocol analyzer, and internet content filter.
5. The concepts of zero trust, different wireless terminologies, and at last, applying mitigation of network-based attack to virtual lab (hands-on) and pentesting the lab (hands-on).

Compared to the old network security course, the new one has almost twice as many lab sessions. This gives candidates the opportunity to get a lot of hands-on experience with different tools and ensure they understand how the technologies work.

Tools Covered in Network Security Course

There are different tools covered in the network security course from InfosecTrain, including:

• Nmap: Nmap, which stands for “Network Mapper,” is a free tool for researching networks that can also be used to check security and ports. It can be used by both small networks and very large networks.
• Metasploit: Metasploit is made for ethical hackers and people who do penetration testing. They can use it to create and use codes against remote systems.
• Wireshark: Wireshark is a great hacking tool for looking at data packets. It can also look at a wide range of standard protocols in detail.
• Nessus: Nessus is the name of the world’s most well-known vulnerability scanner tool. This network vulnerability scanner does an excellent job of detecting severe problems in any system.
• OpenVAS: The Open Vulnerability Assessment System (OpenVAS) is a vulnerability scanner tool that is made to run in a Linux system.
• HYDRA: This tool is a proof-of-concept program that allows hackers and security professionals to demonstrate how straightforward it is to gain unauthorized remote access to the network.
• MEDUSA: Medusa is meant to be a fast, modular login brute-forcer that works in many parallel threads. It works with AFP, CVS, FTP, HTTP, IMAP, SSH, Subversion, VNC, and other protocols.
• pfSense: pfSense is an open-source firewall and routing software based on FreeBSD, an open-source operating system. It is designed to provide organizations or individuals with a secure and reliable network infrastructure.
• PacketFence: PacketFence is an open-source network access control (NAC) system designed to secure wired and wireless networks. It provides authentication, authorization, and enforcement capabilities to make sure that only authorized users and devices can access network infrastructure.
• Velociraptor: Velociraptor is an open-source digital forensics and incident response (DFIR) tool that facilitates endpoint monitoring, data collection, and analysis in a network environment. It is primarily used to detect and investigate security incidents, conduct forensic investigations, and perform threat-hunting activities.
