You Should Know:
Here are some practical commands and codes to enhance your cybersecurity skills, particularly in Linux and Windows environments:
Linux Commands for Cybersecurity:
1. Network Scanning with Nmap:
nmap -sP 192.168.1.0/24 # Ping scan to discover live hosts nmap -sV -O 192.168.1.1 # Version and OS detection nmap -p 1-1000 192.168.1.1 # Port scan for specific range
2. Packet Capture with tcpdump:
tcpdump -i eth0 -w capture.pcap # Capture packets on eth0 interface tcpdump -r capture.pcap # Read captured packets
3. File Integrity Check with md5sum:
md5sum importantfile.txt # Generate MD5 hash for file integrity
4. Firewall Management with iptables:
iptables -A INPUT -p tcp --dport 22 -j ACCEPT # Allow SSH traffic iptables -L # List all firewall rules
5. Log Analysis with grep:
grep "Failed password" /var/log/auth.log # Find failed login attempts
Windows Commands for Cybersecurity:
1. Network Configuration with ipconfig:
ipconfig /all # Display detailed network configuration
2. Port Scanning with PowerShell:
Test-NetConnection -ComputerName 192.168.1.1 -Port 80 # Test port connectivity
3. Event Log Analysis:
Get-EventLog -LogName Security -Newest 50 # Retrieve latest security logs
4. File Hashing with CertUtil:
certutil -hashfile C:\path\to\file SHA256 # Generate SHA256 hash
5. Firewall Management with netsh:
netsh advfirewall set allprofiles state on # Enable firewall netsh advfirewall show allprofiles # Display firewall status
