Secuditor Lite

Secuditor Lite is a free security diagnostic tool for Windows endpoints and network analysis. It identifies system vulnerabilities, improves device Operational Security (OPSEC), detects network elements, and generates structured audit reports in TXT format. Developed for personal and organizational environments, it provides endpoint security status visibility through automated forensic-style analysis.

• Comprehensive endpoint analysis. The function examines local security configurations, group policies, active services, missing security updates, and account settings. Results are presented in a consolidated interface with color coding for rapid risk identification.
• Audit report generation. Creates categorized plain-text (TXT) reports with security findings, configuration baselines, and relevant event logs. Reports can be exported without post-processing for integration into SIEM systems or manual reviews.
• Operational Security (OPSEC) analysis. Executes forensic-style checks on running processes, established network connections, critical registry entries, and scheduled tasks. Detects indicators of compromise and configurations that expose system information.
• IPv4/IPv6 gateway discovery. Identifies active gateways on local networks with dual-stack support. The function lists router IP addresses, DHCP servers, and other infrastructure devices visible from the endpoint.
• Dual-stack network configuration verification. Analyzes the computer's network interfaces, displaying assigned IPv4 and IPv6 addresses, connectivity status, configured DNS servers, and routing tables. Detects inconsistent or insecure configurations.
• Basic TCP/UDP port scanning. Probes specific ports or defined ranges to identify listening services. Helps determine attack surfaces inadvertently exposed on the local system or neighboring hosts.
• Active network element detection. Discovers devices on the local network through ARP requests and ICMP packets. Presents a list of MAC addresses and associated manufacturers, allowing identification of unauthorized or misconfigured devices.
• Software digital signature validation. Verifies that critical system executables and installed applications maintain valid digital signatures issued by trusted certificate authorities. Warns about unsigned drivers or files.
• Antivirus exclusion check. Lists exclusions configured in security software (Microsoft Defender or others) and verifies that sensitive folders or system files are not unnecessarily excluded from real-time scanning.
• Malicious scheduled task analysis. Examines the Windows Task Scheduler for hidden tasks, unusual triggers, or actions executing scripts from temporary locations. Helps detect malware persistence mechanisms.
• Established network connection monitoring. Displays active TCP connections in real-time, the processes associated with each connection, and listening ports. Enables identification of unauthorized communications toward external addresses.
• Security baseline assessment. Compares current system configuration against reference templates (CIS, NIST, or custom) and reports deviations that may pose security risks.

Secuditor Lite was created in 2025 by Menahem Levinski as a security diagnostic solution for Windows endpoints. The application is primarily written in Python, utilizing standard libraries for Windows API interaction and network components. Some critical low-level modules are implemented in C to ensure performance in process and connection analysis.
