Vulnerability Assessment

• Active Assessment is a type of vulnerability assessment where active scanning tools are used to probe systems, networks, or applications for weaknesses. Unlike passive assessments, which rely on existing logs or monitoring without direct interaction, active assessments directly engage with the target environment to uncover vulnerabilities.

  • Tools Used in Active Assessment:

    • Nmap: Network mapping tool for discovering hosts and services on a computer network by sending packets and analyzing responses.
    • Nessus: Vulnerability scanner that actively checks systems for vulnerabilities such as missing patches, misconfigurations, and open ports.
    • Burp Suite: Used for active web application security assessments, particularly for identifying issues like SQL injection, Cross-Site Scripting (XSS), etc.
    • OWASP ZAP: Another tool for actively scanning web applications to find security vulnerabilities.

• Passive Assessment is a vulnerability assessment method that involves monitoring and analyzing existing system data, network traffic, and logs without directly interacting with or probing the target systems. The goal is to identify vulnerabilities or security weaknesses without causing any disruption to services or performance.

  • Tools Used in Passive Assessment:

    • Wireshark: A network protocol analyzer that captures and inspects data packets traversing the network, helping identify traffic anomalies or insecure data transmission.
    • Snort: A network intrusion detection system (NIDS) that passively monitors network traffic to detect suspicious activity.

• External Assessment refers to the process of evaluating the security of an organization’s systems and infrastructure from an outside perspective. The goal is to identify vulnerabilities that could be exploited by attackers who do not have internal access to the network, such as hackers trying to breach the system from the internet.

  • Public-Facing Components:

    • The focus is on systems, services, and applications that are exposed to the internet or external networks. This includes:

    • Web applications

    • External network interfaces
