Now you can see that many titles claim that they can switch to the field of network security within three months and become a network engineer with a monthly income of 15K. So, how much network security knowledge can you learn in 1 month? Is it possible to get started as a network security engineer?
The answer is yes.
Although network knowledge is a broad subject, covering computer network, data communication, network security, network management and many other aspects, it seems very complicated, but our goal is just to get started, so that we can find a promising job or internship , not to become a great god. 1 month is enough time.
Let me share with you how to attack network security during the winter vacation.
To start, in terms of choosing a software system. Many people will be entangled in whether to use Linux or Windows or Mac system. Although the Linux system looks cool, it is not very friendly for novices. Similarly, the Windows system can also learn by using a virtual machine to install a target machine. Therefore, using windows directly has extremely low learning costs.
Then there are some basic "black words" and home page terms, such as broilers, hanging horses, shells, and so on. Pay more attention when watching surfing. When you encounter something you don’t understand, it’s enough to accumulate slowly.
With these preparations, we began to enter the formal study .
1. Theoretical knowledge of network security (2 days)
① Understand the relevant background and prospects of the industry, and determine the development direction.
②Learn laws and regulations related to network security.
③The concept of network security operation.
④Multiple guarantee introduction, guarantee regulations, procedures and norms. (Very important)
2. Penetration testing basics (one week)
①Penetration testing process, classification, standards
②Information collection technology: active/passive information collection, Nmap tools, Google Hacking
③Vulnerability scanning, vulnerability utilization, principles, utilization methods, tools (MSF), Bypass IDS and anti-virus reconnaissance
④ Host attack and defense drill: MS17-010, MS08-067, MS10-046, MS12-20, etc.
3. Operating system basics (one week)
①Common functions and commands of Windows system
②Common functions and commands of Kali Linux system
③Operating system security (system intrusion troubleshooting/system reinforcement basis)
4. Computer network foundation (one week)
①Computer network foundation, protocol and architecture
②Network communication principle, OSI model, data forwarding process
③Common protocol analysis (HTTP, TCP/IP, ARP, etc.)
④Network attack technology and network security defense technology
⑤Web vulnerability principle and defense: active/passive attack, DDOS attack, CVE vulnerability recurrence
5. Basic database operations (2 days)
①Database basics
②SQL language basics
③Database security reinforcement
6. Web penetration (1 week)
①Introduction to HTML, CSS and JavaScript
②OWASP Top10
③Web vulnerability scanning tools
④Web penetration tools: Nmap, BurpSuite, SQLMap, others (chopper, missing scan, etc.)
Congratulations, if you learn this, you can basically work in a job related to network security, such as penetration testing, web penetration, security services, security analysis and other positions; if you learn the security module well, you can also work as a security engineer. The salary range is 6k-15k.
So far, about a month. You've become a "script kiddie". So do you still want to explore further?
