Learning Objectives
- Understand the key resources available in SecArchive for cybersecurity certification prep.
- Learn essential Linux and Windows commands for security testing and system hardening.
- Explore vulnerability exploitation and mitigation techniques using real-world tools.
You Should Know
1. Essential Linux Commands for Security Testing
Command:
nmap -sV -A -T4 target_ip
What It Does:
This Nmap command performs an aggressive scan (-A) with version detection (-sV) and fast timing (-T4) to identify open ports, services, and potential vulnerabilities on a target system.
How to Use It:
1. Install Nmap if not already present:
sudo apt install nmap Debian/Ubuntu
2. Run the scan against a target IP:
nmap -sV -A -T4 192.168.1.1
3. Analyze the output for service versions and potential attack vectors.
2. Windows Security Hardening with PowerShell
Command:
Get-Service | Where-Object {$_.Status -eq "Running"} | Select-Object Name, DisplayName
What It Does:
This PowerShell command lists all running services on a Windows system, helping administrators identify unnecessary services that could be disabled to reduce attack surface.
How to Use It:
1. Open PowerShell as Administrator.
2. Execute the command to view running services.
3. Disable unnecessary services using:
Stop-Service -Name "ServiceName" Set-Service -Name "ServiceName" -StartupType Disabled
3. Extracting Metadata from Files with ExifTool
Command:
exiftool suspicious_file.jpg
What It Does:
ExifTool extracts metadata (e.g., GPS coordinates, timestamps, camera details) from files, useful in forensic investigations.
How to Use It:
1. Install ExifTool:
sudo apt install libimage-exiftool-perl
2. Run the tool on a file:
exiftool suspect_image.jpg
3. Check for hidden data or anomalies.
4. Detecting Open Ports with Netcat
Command:
nc -zv target_ip 1-1000
What It Does:
Netcat (nc) performs a basic port scan to check for open ports between 1 and 1000 on a target system.
How to Use It:
1. Install Netcat:
sudo apt install netcat
2. Scan a target:
nc -zv 192.168.1.1 1-1000
3. Review open ports for further investigation.
5. Securing SSH Access
Command:
sudo nano /etc/ssh/sshd_config
What It Does:
Editing the SSH configuration file allows hardening remote access by disabling root login and enforcing key-based authentication.
How to Use It:
1. Open the SSH config file:
sudo nano /etc/ssh/sshd_config
2. Modify the following lines:
PermitRootLogin no PasswordAuthentication no
3. Restart SSH:
sudo systemctl restart sshd
