Table of Contents

Description

Network security is a broad term that covers multiple technologies, devices, and processes. Nowadays, every organization, regardless of size, industry, or infrastructure, requires a network security expert in place to protect it from the ever-growing landscape of cyber threats today.

After this course, you will be able to discover security vulnerabilities across the entire network by using network hacking techniques and vulnerability scanning. You will understand the various types of firewalls that are available and master the hardening for both Windows and Linux servers.

How to make the most of this course?

In order to succeed in the course, the following requirements must be met:

  • Participation in all practical laboratories,
  • Self-work at home between lessons,
  • Repetition of materials, self-learning, performing tasks, etc …

In addition to regular classroom studies, the participant is required to practice at least 10 hours a week in order to gain practical experience in the field.

Real Cases Studies

Case Study #1 (NS001)
Just before last Christmas and year-end holidays, Citrix announced that its Citrix Application Delivery Controller (ADC) and Citrix Gateway are vulnerable. The vulnerability allows the attacker to execute arbitrary code on the servers. As the Network security expert, your company put you in charge of this case. Use your Network abilities to find the vulnerability and mitigate it
Reference
Case Study #2 (NS002)
Kaspersky Lab reports that A massive DNS cache poisoning attack attempting to infect users trying to access websites is currently underway in Brazil. Several large ISPs in the highly connected country have been affected by the attack. You have been tasked to identify details related to the attack to remediate any damage discovered in the identification phase.
