Ethical Hacking: Introduction to Ethical Hacking (Updated)

https://www.linkedin.com/learning/ethical-hacking-introduction-to-ethical-hacking/
What is ethical hacking? When it comes to cybersecurity, hacking comes in many colors: white, grey, black, and shades in between. White hat hackers use their skills for good. They practice ethical hacking: involved testing to see if an organization's network is vulnerable to outside attacks. Ethical hacking is key to strengthening network security, and it's one of the most desired skills for any IT security professional. If you're interested in becoming an ethical hacker, or getting started securing your own network, this introduction is for you. Security expert Lisa Bock explores today's threat landscape, dissecting the top attack vectors and motives for attacks. Lisa identifies a variety of ways to secure an organization, explores policies that help enforce security objectives, and more.

Network address translation is used to allow devices on a private network and access resources on the global Internet. This course introduces you to NAT, examines different types of NAT, and teaches you how to implement and troubleshoot them.

TCP is a core protocol driving business applications, but is often a blind spot in IT organizations. A thorough understanding of TCP can speed up network and application troubleshooting, empowering engineers to quickly resolve problems.

The IP address is a fundamental building block for a functioning modern network. In this course, instructor Anthony Sequeira explains the basics of IP addressing, the components of an IP address, aggregation, and more. Anthony begins by describing what the IP address does and why it is critical in a successful network. He goes into the structure of IPv4 and IPv6 addresses. Anthony shows you how to work with the classful addressing system for IP addresses, then goes over subnet masks and subnet addressing. He covers how variable length subnet masking (VLSM) permits the creation of optimal "right-sized" network segments. Anthony walks you through CIDR and IP address aggregation. He explains special use addresses, then concludes with how IP services such as DHCP, DNS, and NAT can benefit your network.

If you watched our Introduction to Ethical Hacking course, you know the basics of ethical hacking. Ethical hackers use their knowledge for good: to test if an organization's network is vulnerable to outside attacks. But where do they start? With footprinting (aka reconnaissance), the process of gathering information about computers and the people to which they belong. In this course, Lisa Bock introduces the concepts, tools, and techniques behind footprinting: finding related websites, determining OS and location information, identifying users through social media and financial services, tracking email, and more. Footprinting relies on tools as simple as a web search and dumpster diving, and as complex as DNS interrogation and traceroute analysis. Lisa shows how to put these nefarious sounding tools to work for good, and mitigate any risks an organization has to these types of attacks.

Servers are the heavy lifters of IT. They power the internet, email, enterprise-level applications, databases, local networks, and more. While most users have a superficial understanding of servers, system administrators and IT pros must know them intimately. You must be prepared to configure, deploy, and maintain a variety of servers—with high availability and scalability. This course covers the fundamentals of servers, including popular server operating systems such as Windows Server and Linux. It's designed for the entry-level IT student who needs a basic understanding of server architecture, user administration, virtualization, storage, security, networking, and disaster recovery. Instructor Ed Liberman, an IT consultant and trainer for over 20 years, also reviews troubleshooting theory and tools, so you can understand common problems that can arise with servers and how to solve them.

Lynda - Ethical Hacking: Evading IDS, Firewalls, and Honeypots

https://www.lynda.com/IT-tutorials/Ethical-Hacking-Evading-IDS-Firewalls-Honeypots/5043084-2.html
Ethical hacking—testing to see if an organization's network is vulnerable to outside attacks—is a desired skill for many IT security professionals. In this course, cybersecurity expert Malcolm Shore prepares you to take your first steps into testing client defenses. Malcolm provides you with an overview of firewall technology, detailing how firewalls work in both Windows and Linux, as well as how to set up a firewall simulation in a GNS3 network. Next, he goes over web application firewalls, API gateway threat mitigation solutions, and how to use honeypots to detect intruders. Finally, he covers the main ways to manage a suspected intrusion, including how to use the Security Onion intrusion detection system (IDS).

Lynda - Wireshark: Malware and Forensics

https://www.lynda.com/Wireshark-tutorials/Wireshark-Malware-Forensics/624305-2.html
Security devices on a network scoop up traffic and then analyze the field values to allow or deny specific traffic. As smart as the devices are, there are times when some threats slip through the cracks. Wireshark is a free protocol analysis tool that is used to baseline a network, actively monitor changes, identify common attack signatures, build firewall rules, detect issues, and quickly remove threats from the network. This course covers how to use Wireshark for deep packet analysis, capturing, and forensics. Learn how to keep your networks secure against malware and cyberattacks by implementing solutions that detect and handle unusual traffic.
