X3-DNS

X3-DNS is a robust and user-friendly DNS vulnerability assessment tool designed to help users identify and mitigate potential security risks in their domain's DNS configuration. This tool performs comprehensive checks for common DNS vulnerabilities, including SPF, DKIM, DMARC, DNSSEC, MX, and CAA records, providing detailed results and actionable recommendations to enhance DNS security.

Features

• SPF Record Validation: Ensures the presence and correctness of SPF records to prevent email spoofing.
• DKIM Record Check: Searches for DKIM records using common selectors to verify email integrity.
• DMARC Record Verification: Confirms the existence of DMARC records to enforce email authentication policies.
• DNSSEC Configuration Check: Validates DNSSEC setup to protect against DNS spoofing and cache poisoning.
• MX Record Validation: Checks for valid MX records to ensure reliable email delivery.
• CAA Record Validation: Ensures the presence of CAA records to restrict certificate issuance to authorized CAs.

How It Works

X3-DNS leverages the dnspython library to perform DNS queries and validate the presence and correctness of various DNS records. The tool is built with a user-friendly interface using tkinter and ttkthemes, allowing users to easily input domains, select vulnerabilities to check, and view results in a structured format.

Installation

To run X3-DNS from source, follow these steps:

1. Clone the Repository:

   git clone https://github.com/mubbashirulislam/X3-DNS.git
   cd X3-DNS
