The Reason Why I roll out this course Hi All, This is Trevor Shi, I was the IT support back in 2019, I created the CyberRookie ProjectSelf training project version 1, spent a year training myself to be Security Analyst.  From my own experience, to be a qualified Cyber Analyst, it should at least match these four requirements: 1. Having the cyber-related certificated 2. Having cyber knowledge 3. Having cyber hands-on skills 4. With IT work Experience The CyberRookie Course is trying to cover these 4 domains with limited cost to get free cyber-related certificated, gain cyber knowledge, practice cyber hands-on skills, and get a deep understanding of IT systems.  I believe that How good you are at cybersecurity is based on how deep you understanding the IT system. CyberRookie Project CyberRookie Project is an 8 weeks self-Studying project. Currently is in version 2.1. Our goals  are to help people with limited IT/Cyber background into IT/Cyber field can: Learning cyber skill...

  To Be A Cyber Man: Trevor Shi CyberSecurity Blue team HomeLab V3.0     I recently updated my cybersecurity  HomeLab . The design is more focused on the Bule team. T his lab design can provide basic functionally IT services with continual protection and log monitoring to detect the cyber attack.     Upgraded history:     1. Upgraded  virtualization solution from Vmware player to Vmware ESXi.     2.  Added WatchGuard Firewall as the gateway.       3. Added  virtual  PfSense Firewall in front of BuleTeam Lab as the gateway.     4. Deployed EVE-NG  with Fortigate firewall SD-WAN and PaloAlto lab.      Licensing and Cost:     One of the benefits of this Lab is  saving money. Buying one i5 PC can set it up. You do not need to put a physical firewall in front of the network, The virtual FW works just fine.      Diagram:
