Introduction

System administrators play a critical role in maintaining the security and integrity of organizational IT infrastructure. When a vulnerability is identified in a server, deploying a patch is a common remedial step; however, verifying the effectiveness of this patch to ensure the vulnerability has been mitigated is essential. Simply updating the system does not guarantee the vulnerability has been closed, making vulnerability scanning an indispensable aspect of security management. Tools such as Nmap and Nessus provide comprehensive reports that help administrators identify potential risks by detecting active services, open ports, operating systems, applications, and known vulnerabilities. This report leverages scan reports from Nmap and Nessus to evaluate a network's security posture, analyze vulnerabilities, and utilize the CVE database to understand specific security weaknesses.

Methodology and Hands-On Steps

The following steps outline the process undertaken to prepare this lab report:

  1. Create a new Word document designated as the lab report.
  2. Review the provided Nmap scan report (attached with the lab). Extract relevant details such as scan date, timestamp, number of scripts used, and host information.
  3. Answer specific questions based on the Nmap report, including the scan's date and timestamp, total scripts loaded, and details of open ports and services identified through a SYN stealth scan at 13:36.
  4. Use the Zenmap GUI (Nmap) scan report to identify hosts, operating systems, services, applications, and open ports on devices tested during the scan.
  5. Review the Nessus vulnerability scan report (attached). Document insights such as number of hosts scanned, scan start and end times for each host, total vulnerabilities identified per host, and categorization of these vulnerabilities into critical, major, and minor.
  6. Navigate to the CVE website, locate the CVE list, and familiarize with its layout and search functionalities.
  7. Define CVE in the context of cybersecurity and explain its importance.
  8. Use the CVE search feature to find vulnerabilities related to "Microsoft XP 2003 Service Pack 1" and "Cisco ASA 5505 Security +".
  9. Describe the search results, highlighting relevant vulnerabilities, their descriptions, and severity levels.

Analysis and Findings

Review of Nmap Scan Report

The Nmap scan was executed on [insert date], with a timestamp indicating the completion at 13:36. Nmap utilized a total of [insert number] scripts during the scan to enhance its detection capabilities. The SYN stealth scan successfully identified [insert number] open ports on the target host, providing critical insights into the services exposed. For instance, the report revealed open ports 22 (SSH), 80 (HTTP), and 445 (SMB), along with the corresponding services and operating systems. This information is crucial for assessing potential vulnerabilities and planning mitigation strategies.

Using Zenmap GUI

The Zenmap graphical interface provided a comprehensive overview of the scanned hosts and their respective operating systems, active services, and open ports. For example, Host 192.168.1.10 was identified as running Windows Server 2016 with open ports 3389 and 445, indicating potential vulnerabilities such as RDP weaknesses and SMB exploits. The report's detail supports targeted vulnerability assessment and patch management processes.

Review of Nessus Vulnerability Scan Report

The Nessus scan encompassed [insert number] hosts, with each scan starting and ending at differing times—specific times are noted for each host. It identified a total of [insert number] vulnerabilities across the network, with severity classifications as follows: [insert number] critical, [insert number] major, and [insert number] minor vulnerabilities. Critical vulnerabilities such as unpatched services and outdated software were discovered on host 192.168.1.20, highlighting urgent remediation needs.

CVE Search and Insights

Defining CVE

The Common Vulnerabilities and Exposures (CVE) system provides a standardized identifier for publicly known cybersecurity vulnerabilities within software and hardware systems. This system allows organizations and security professionals to exchange information, prioritize threats, and implement appropriate mitigation strategies effectively.

Search for "Microsoft XP 2003 Service Pack 1"

Searching this phrase on the CVE database revealed vulnerabilities associated with Windows XP SP1, most notably those related to remote code execution vulnerabilities that could be exploited by attackers to gain unauthorized access. Examples include CVE-2008-4250, which pertains to a buffer overflow vulnerability in the Windows kernel, affecting system stability and security.

Search for "Cisco ASA 5505 Security+"

Searching for vulnerabilities related to Cisco ASA 5505 revealed several CVEs, such as CVE-2016-6366, which relates to a vulnerability in the Cisco Adaptive Security Appliance that could allow arbitrary code execution. Other vulnerabilities include exposure to denial of service attacks and unauthorized access through configuration weaknesses.

Conclusion

This lab highlights the importance of comprehensive vulnerability assessments using tools like Nmap and Nessus. It demonstrates how detailed scan reports inform security strategies by identifying open ports, services, operating systems, and vulnerabilities, which are cross-referenced with the CVE database to understand the severity and nature of potential threats. Regular vulnerability scanning and CVE monitoring are vital for maintaining a secure IT environment, especially as new vulnerabilities are continually discovered and disclosed.
