Description

Large and small companies face a critical stage; cyber-attacks have transformed
dramatically over the past few years. Unfortunately, organizations are still being breached too
often and are under more pressure than ever to secure their systems. The Network Security
course aims to address cyber challenges eHperienced on the network level. The course covers
various attack techniques and how to defend against them.
The course sets the groundwork for later specialization in cyber forensics, advanced cyber defense,
and penetration testing.
The course helps prepare for the certification eHams Linux+ (CompTlA) and LPIC-2 (LPI).

Target Audience

The course targets participants with basic IT or networking knowledge who wish to understand corporate cybersecurity and cyber defense from a technical perspective.

Objectives

  • Becoming familiar with the cyber threat landscapes
  • Acquiring the knowledge and tools to recognize threats in the network
  • Understanding cyber-attacks
  • Becoming familiar with a variety of available tools for performing security-related tasks

Module 1: Introduction to Linux

Students will study the Linux 05 fundamentals. This module uses Linux commands,
manipulating teHt and command outputs, understanding terminal-emulators, permissions, and other
security concepts.

Virtualization

  • Introduction to Virtualization
  • About Linux Distro
  • Installing Linux
  • Working with VMWare
  • Bridged vs. NAT

Working with Linux

  • Linux Directories
  • Linux Users
  • Packages
  • File Manipulation Commands
  • Text and File Manipulation Technics
  • Writing Linux Sripts

Module 2: Networking

During this module, participants will study network infrastructures, common network types, network Layers, communication between protocols, communication between network
devices from different Layers, and network anonymity methods.

Protocols and Services

  • TCP/IP and OSI Model
  • Network Routing Basics
  • DNS
  • DHCP
  • ARP
  • Remote Connection Protocols

Wireshark — Diving into Packets

  • Non-Secure and Secure Packets
  • Filtering and Parsing
  • Extracting Objects and Files from PCAP Files

Module 3: Introduction to Network Forensics

Large organizations these days suffer greatly from network attacks and malicious intrusions. Those who manage the organization’s network have an immense impact on ensuring its safety. This module will introduce participants to Network Forensics and learn how to locate and better understand various attacks.

Windows Tools

  • NetworkMiner
  • Advanced Wireshark
  • OS-Fingerprinting
  • Detecting Suspicious Traffic
  • Sysinternals

Linux Tools

  • TShark – Network Analyzing Automation
  • Capture Packet Data from Live Network
  • Filter Packets from Live Network
  • Filter Packet from PCAP File
  • Traffic Statistics
  • File-Carving
  • Parsing Traffic Logs
  • CAPlnfo

Module 4: Cyber Security

This module’s primary goal is to teach participants to embrace the attacker state-of-mind to recognize the necessary defense mechanisms. Participants will deal with several types of attacks. Students will learn about hash functions; furthermore, they will learn how wireless networks are attacked and how they are vulnerable to those attacks. Social engineering and honeypot techniques will also be demonstrated.

Cyber Security Vectors

  • Anti-Viruses
  • DoS and DDoS
  • CNC Servers and Botnets
  • Steganography

Network Attacks

  • Scanning Methods
  • MiTM
  • ARP Poisoning
  • DHCP Starvation
  • LLMNR Attacks
  • Offline Password Brute-Force
  • Working with Responder

Cyber Attack Practice

  • Payloads: Reverse vs.
  • Bind Privilege Escalation
