Developing Technical Skills

1. Programming
2. Learn languages such as Python, Java, or C++ for scripting and automation.
3. Example: Writing a simple port scanner in Python.

import socket

def scan_ports(ip, port_range):
    open_ports = []
    for port in port_range:
        sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        sock.settimeout(1)
        result = sock.connect_ex((ip, port))
        if result == 0:
            open_ports.append(port)
        sock.close()
    return open_ports

ip_address = '192.168.1.1'
port_range = range(1, 1024)
print("Open ports:", scan_ports(ip_address, port_range))

1. Networking
2. Understand TCP/IP, DNS, and other networking protocols.

3. Use tools like Wireshark to analyze network traffic.

4. Operating Systems

5. Gain proficiency in Linux and Windows operating systems.
6. Set up a home lab using virtual machines to practice configurations and security settings.
