 # PT-Environment
 Local penetration test experimental environment
+
+## What's this
+
+This is a Network topology designed by Cisco Packet Tracer in my own laptop.
+
+## Why do this
+
+In the daily APT attack and defense and penetration testing process, we will encounter a very complicated internal network environment(maybe the Windows AD environment), we need to ensure that there will be no leakage before some actual operations.
+
+So, I used the VMware workstation to build this whole experimental environment in my laptop. 
+
+This is just a simple topology and design file. After that, I will write about the specific configuration process and details when I am free.
+
+This project has no technical content, just an archive of its own learning knowledge process.
+
+## What it looks like now

+
+
+## In the future
+
+I did a "Cyber Range" project at the university, mainly for cyber security teaching and training. At that time, it was all the systems built with a VMware Esxi server with 200G memory. The system system at that time was as follows:

+
+Personally, in fact, the "network shooting range" is an important network security infrastructure for individuals, organizations, companies and even the country. A good shooting range can be a good experimental network environment and exercise offensive and defensive techniques.
+
+Maybe in the future, the above shooting range will be done again and become a real enterprise product.
