Obtaining a Cybersecurity Professional License is a significant achievement for any cybersecurity professional. This license, granted under the Cybersecurity Act, 2020 (Act 1038) by the Cyber Security Authority of Ghana, signifies a high level of expertise and commitment to the field. In this article, we will explore some practical commands and codes that can be used in penetration testing, digital forensics, and incident response, which are critical areas in cybersecurity.
Penetration Testing Commands
1. Nmap Scan
nmap -sV -sC -O target_ip
This command performs a version detection, script scanning, and OS detection on the target IP.
2. Metasploit Framework
msfconsole use exploit/windows/smb/ms17_010_eternalblue set RHOSTS target_ip exploit
This command sequence sets up and executes the EternalBlue exploit on a target machine.
Digital Forensics Commands
1. Autopsy
autopsy
Launches the Autopsy GUI for digital forensics investigations.
2. Foremost File Recovery
foremost -i /dev/sdb1 -o /recovery/output
Recovers files from a disk image or partition.
Incident Response Commands
1. Log Analysis with Grep
grep "Failed password" /var/log/auth.log
Searches for failed password attempts in the authentication log.
2. Network Traffic Capture with Tcpdump
tcpdump -i eth0 -w capture.pcap
Captures network traffic on the eth0 interface and writes it to a file.
What Undercode Say
Cybersecurity is a dynamic and ever-evolving field that requires continuous learning and adaptation. The commands and codes provided in this article are just a starting point for those interested in penetration testing, digital forensics, and incident response. Here are some additional Linux commands and resources that can further enhance your cybersecurity skills:

3. Malware Analysis with Cuckoo Sandbox
cuckoo submit malware.exe
Submits a malware sample for analysis.
4. Vulnerability Scanning with OpenVAS
openvas-start
Starts the OpenVAS vulnerability scanner.
5. Log Management with Syslog
sudo nano /etc/rsyslog.conf
Configures syslog for centralized log management.
6. Intrusion Detection with Snort
snort -A console -q -c /etc/snort/snort.conf -i eth0
Runs Snort in intrusion detection mode on the eth0 interface.
7. File Integrity Checking with AIDE
aide --check
Checks the integrity of files on the system.
8. Password Cracking with John the Ripper
john --wordlist=/usr/share/wordlists/rockyou.txt hashes.txt
Uses a wordlist to crack passwords.
9. Network Mapping with Netdiscover
netdiscover -i eth0
Discovers live hosts on the network.
10. Web Application Scanning with Nikto
nikto -h target_url
Scans a web application for vulnerabilities.
