In this video, we will look at hashing, which is the conversion of key/string/variable into a hash using an algorithm used in malware and antimalware products.

This is a brief overview of the concepts to be learned from this section, including the different kinds of attacks, Hashcat, and PowerShell.

This video demonstrates using Zenmap, the graphical user interface for NMAP, to scan different networks.

In this video, we will understand a firewall and the intrusion detecting system in NMAP for a packet or probe coming specifically from NMAP.

This video elaborates on NMAP's different techniques for scanning networks using the available network probes.

This video continues where we left off, understanding the host discovery controls and the scanning techniques used briefly.

In this lesson, we will look at the different probes used by the NMAP, including ICMP Echo request, TCP Syn packet to port 443, TCP ACK packet to port 80, and ICMP timestamp request.

This video will teach us about the six port states: open, closed, filtered, unfiltered, closed/filtered, and open/filtered.

After installing and configuring NMAP, we will look at how this NMAP scanning program works.

This video demonstrates how to install, set up, and configure the NMAP, a powerful network scanner.

This video briefly outlines the concepts you will learn in this section regarding NMAP, its installation, and its use.

In this lesson, we will look at creating a sample outbound rule; we will test it out by trying to block internet access by setting outbound rules for the Google Chrome browser.

This video walks us through the built-in firewall of the Windows 10 operating system. The advantages of using the firewall, and how it protects the operating system.

Here, you will learn how to harden networks. What devices and protocols are available to harden a network from being hacked?

This video demonstrates how the TCP protocol operates in a 3-way mode through host-server-host communication.

Here, we will understand transmission control protocol and user datagram protocol and the fundamental differences between the two.

This video is a detailed introduction to Network Address Translation, allowing computers to share the same public IP address.

This video explores the ports, networks, and protocols used to operate each port.

This video takes us through the different commands to operate the DHCP and protect a system or network from attacks.

This video introduces us to the dynamic host configuration protocol and the domain name service.

This video briefly outlines the section concepts, including a typical home network setup, DHCP and DNS, commands used in them, TCP versus UDP, and firewalls and hardening networks to prevent attacks.

This continuation of the previous video explains phishing emails in detail and how to avoid phishing attacks.

This video illustrates how to create or craft a phishing email.

This video takes us through the various updates available through operating systems that we can use to avoid phishing attacks as much as possible.
