You Should Know:
1. Linux Command for Network Security:
- Use `nmap` to scan for open ports and services on a network.
nmap -sV 192.168.1.1
- This command will scan the IP address `192.168.1.1` and provide detailed information about the services running on open ports.
2. Windows Command for Firewall Configuration:
- Use `netsh` to configure Windows Firewall settings.
netsh advfirewall set allprofiles state on
- This command enables the firewall for all profiles (Domain, Private, and Public).
3. Cybersecurity Best Practices:
- Regularly update your software and systems to patch vulnerabilities.
- Use strong, unique passwords and enable multi-factor authentication (MFA) wherever possible.
- Conduct regular security audits and penetration testing to identify and mitigate risks.
4. Linux Command for Log Monitoring:
- Use `tail` to monitor log files in real-time.
tail -f /var/log/syslog
- This command will display the last 10 lines of the syslog file and update in real-time as new entries are added.
5. Windows Command for Event Logs:
- Use `wevtutil` to query and manage Windows Event Logs.
wevtutil qe System /c:5 /f:text
- This command retrieves the last 5 entries from the System log.
6. Cybersecurity Tools:
- Wireshark: A network protocol analyzer that lets you capture and interactively browse the traffic running on a computer network.
- Metasploit: A penetration testing framework that helps you find, exploit, and validate vulnerabilities.
7. Linux Command for File Integrity Checking:
- Use `sha256sum` to generate a checksum for a file.
sha256sum importantfile.txt
- This command will generate a SHA-256 checksum for
importantfile.txt, which can be used to verify file integrity.
8. Windows Command for User Account Management:
- Use `net user` to manage user accounts.
net user username /add
- This command adds a new user to the system.
