Introduction Vulnerability assessments are crucial for identifying weaknesses in your system before attackers exploit them. With open-source tools, even beginners can get started. In this blog, we’ll guide you through conducting a basic vulnerability assessment using tools like Nmap , Nikto , and OpenVAS . Setting Up Your Environment Before diving in, ensure you have a safe testing environment: Use a virtual machine (VM) or isolated network. Download and install the tools: Nmap : Network scanning tool. Nikto : Web server vulnerability scanner. OpenVAS : Comprehensive vulnerability management system. Scanning with Nmap What it does: Nmap scans your network to identify open ports and services. Command to use: nmap -sS -sV -O -T4 <target IP> Explanation: -sS : Stealth scan. -sV : Service version detection. -O : OS detection. -T4 : Faster scan speed.
