Identify and Analyze Security  Vulnerabilities in Target Systems

Business Scenario

You are working as a Cyber Security Analyst at SecureXit. During a routine security assessment, your team has been assigned to evaluate a target system for potential security weaknesses. Before implementing any security controls, it is important to identify vulnerabilities and misconfigurations that could be exploited by attackers.

Using vulnerability scanning tools, you will scan the target system to discover known vulnerabilities, insecure configurations, and exposed services.

Pre-Lab Preparation

The identified findings will be analyzed based on their severity levels, such as Low,Medium, High, and Critical, to understand their potential impact on the organization.

The collected results will then be reviewed and documented in a vulnerability assessment report to help the security team prioritize remediation efforts and improve the overall security posture of the environment.
