Implement IP Address and DNS Scanning for VirusTotal Integration

[0x11DFE]

Description:

Currently, Portmaster lacks the ability to scan IP addresses and DNS entries against VirusTotal's database for potential threats. This limits Portmaster's effectiveness in detecting and blocking malicious activity that might bypass traditional list based filtering.

Benefits of Implementation:

• Enhanced Security: Enabling IP address and DNS scanning would allow Portmaster to identify and block connections to known malicious servers and domains, even if they use non-standard ports or dynamic IP addresses.
• Proactive Defense: By proactively checking IP addresses and DNS entries, Portmaster could prevent users from inadvertently connecting to harmful websites or services, reducing the risk of malware infections and data breaches.
• Comprehensive Protection: Integrating IP address and DNS scanning with VirusTotal would further strengthen Portmaster's existing port-based filtering, providing users with more comprehensive protection against a wider range of threats.

Technical Considerations:

• Performance Impact: Scanning IP addresses and DNS entries could potentially increase Portmaster's resource usage and processing time, especially for users with large numbers of connections. Careful optimization would be necessary to minimize any performance impact.
• False Positives: It's important to ensure that Portmaster's implementation minimizes false positives, which could disrupt legitimate network traffic and frustrate users.
• User Control: Provide users with the ability to enable or disable IP address and DNS scanning, as well as configure the sensitivity of the detection algorithms.

Conclusion:

Adding IP address and DNS scanning capabilities to Portmaster, with integration into VirusTotal, would significantly enhance its ability to detect and block malicious activity, providing users with more comprehensive and proactive network security.

Note: This suggestion focuses on improving Portmaster's security features. Other potential enhancements, such as performance optimizations or user interface improvements, could be addressed in separate suggestions.
