DSAT-DNSSecurityAnalysisTool

Description

The DNS Security Analysis Tool is a Python-based utility designed to conduct an in-depth security analysis of DNS configurations for multiple domains. It queries various DNS record types and performs specialized checks, including DNSSEC verification, open resolver detection, and reverse DNS mismatch analysis. This tool is handy for network administrators, cybersecurity professionals, and anyone interested in DNS security.

Key Features

• Comprehensive DNS Record Queries: Retrieves various DNS record types such as A, AAAA, MX, TXT, NS, CNAME, SOA, SPF, DKIM, DNSKEY, DS.
• DNSSEC Verification: Checks for the implementation of DNSSEC, enhancing the security of DNS queries.
• Open Resolver Detection: Identifies potential open resolvers that might be used in DNS amplification attacks.
• Reverse DNS Mismatch Analysis: Examines mismatches between forward and reverse DNS records.
• Anomaly Detection: Basic analysis to identify potential anomalies and unusual entries in DNS records.
• Response Code Logging: Captures and logs DNS response codes for each query for further analysis.
• Domain Name Validation: whether the domain exists or not. If not, no further check will be done.
• Empty Row filtering: If the file contains an empty row, it will check and skip that part.

Key Notes:

• check_open_resolver Function: This function uses the dig command to determine if the given domain is an open resolver. Ensure the environment where this script is run has the dig command available.
• check_dnssec Function: Performs DNSSEC validation for the domain using the specified nameservers.
• analyze_records Function: Placeholder for analyzing DNS records for anomalies. Specific logic can be implemented based on the requirements.
• Reporting and Processing: The script generates a report in the chosen format and processes each domain in the input file, showing progress with a tqdm progress bar.

This script should now provide comprehensive DNS security analysis, including open resolver checking and DNSSEC validation, among other features. Test this script in your environment to ensure it performs as expected. Please let me know if you encounter any issues or need further modifications!
