This report presents a comprehensive network security assessment, detailing vulnerabilities discovered through various techniques, including physical inventory, automated tools (NMAP, Nessus), and manual inspection. The assessment reveals critical issues such as missing security patches, misconfigured firewall rules, open USB access, weak or default passwords, insecure wireless networks (WEP and rogue access points), inactive intrusion prevention system (IPS) signatures, insecure data flow over public and MPLS networks, and a lack of security device monitoring and log management software. The analysis highlights the potential impact of these vulnerabilities on data confidentiality, integrity, and availability (CIA), emphasizing the need for immediate remediation. The report underscores the importance of timely patch management, robust firewall configurations, USB port security, strong password policies, secure wireless protocols, active IPS signatures, data encryption, and the implementation of security monitoring tools to detect and mitigate threats. The findings underscore the need for a proactive approach to network security, including regular assessments, policy enforcement, and continuous monitoring to protect against potential attacks and data breaches.
