Security Monitoring & Reputation Management

Overview

This document outlines free and low-cost security resources to maintain trust, safety, and reputation across our peer-to-peer charity platforms. Server security and hardeneing are covered separately. Given our commitment to 100% peer-to-peer charity with zero overhead costs, we focus exclusively on free-tier services and tools.

Core Security Principles

  • Trust is paramount: Our platform connects donors directly with recipients – any security breach undermines the entire mission
  • Frugal approach: Using free tools allows us to maintain zero operational costs and true 100% peer-to-peer giving
  • Multi-layered defense: Combining multiple free tools provides comprehensive coverage
  • Proactive monitoring: Regular checks prevent problems before they damage reputation

1. Website Security Monitoring

2. Domain & IP Reputation Monitoring

Why This Matters

If our domains or IPs get blacklisted, legitimate donation emails may never reach recipients, destroying trust in the platform.

Tools

MXToolbox Blacklist Check

ZeroBounce Blacklist Checker

EasyDMARC IP & Domain Reputation

URLVoid Domain Checker

  • URL: https://www.urlvoid.com/
  • Use Cases: Check domain reputation and safety
  • Frequency: Weekly checks of all our domains

What to Do If Blacklisted

  1. Identify which blacklist (use tools above)
  2. Investigate cause (compromised server, spam complaints, malware)
  3. Fix the underlying issue
  4. Request delisting from each blacklist (follow their specific procedures)
  5. Implement stronger email authentication (SPF, DKIM, DMARC)
  6. Monitor closely for re-listing

3. Advertiser Verification

Pre-Approval Process

Before accepting any advertiser, we must verify their legitimacy and safety:

Step 1: Manual Review

  • Verify the advertiser’s website exists and is professional
  • Check their about page, contact information, and business registration
  • Look for red flags (too-good-to-be-true claims, poor English, pressure tactics)

Step 2: Security Scanning

Run through these free tools:

  1. VirusTotal: Check advertiser’s domain and any file downloads
  2. URLVoid: Verify reputation across 30+ databases
  3. Google Safe Browsing: Check at https://transparencyreport.google.com/safe-browsing/search
  4. Sucuri SiteCheck: Scan for malware

Step 3: Content Review

  • Review all ad creative (images, text, videos)
  • Ensure ads don’t contain:
    • Malicious links
    • Phishing attempts
    • Deceptive claims
    • Adult content
    • Cryptocurrency scams
    • Multi-level marketing schemes
    • Anything that could harm our reputation

Ongoing Monitoring

  • Re-scan advertiser sites monthly
  • Monitor for complaints from users
  • Be prepared to immediately remove problematic advertisers

4. Content Moderation (Social Media/Nostr Integration)

Challenge

Our platform integrates with Nostr for social features. We need to moderate public posts to prevent:

  • Hate speech and harassment
  • Spam and scams
  • Child exploitation material (CSAM)
  • Phishing attempts
  • Misinformation that harms the charity mission
  • Personal information leaks

Free/Affordable Content Moderation Options

Community-Based Moderation

  • Cost: Free (volunteer moderators)
  • Approach: Recruit trusted community members as volunteer moderators
  • Tools: Simple reporting system, moderator dashboard
  • Limitations: Doesn’t scale well, slow response times

Open Source Content Moderation

Consider deploying one of these free, self-hosted solutions:

  • Perspective API (Google): Free API for toxic comment detection
  • Detoxify (Python library): Open-source toxic comment classifier

Hybrid Approach (Recommended)

  1. Automated pre-screening: Use free APIs to flag potentially problematic content
  2. User reporting: Allow users to flag inappropriate content
  3. Volunteer moderators: Review flagged content and make final decisions
  4. Clear policies: Publish transparent community guidelines

Free Content Moderation APIs (with limitations)

ModerateContent.com

  • URL: https://www.moderatecontent.com/
  • Free Tier: 1,000,000 images/month
  • Features: Image moderation for adult content
  • Use Case: Profile pictures, user-uploaded images

Microsoft Azure Content Moderator

  • Note: Has a free tier but with strict limits
  • Features: Text and image moderation

Perspective API (Google)

  • URL: https://perspectiveapi.com/
  • Free Tier: Available with registration
  • Features: Toxic comment detection
  • Use Case: Auto-flag toxic posts for review

Content Moderation Workflow

  1. Real-time filtering: Block obvious spam/malicious content automatically
  2. User reports: Easy “Report” button on all posts
  3. Moderator queue: Flagged content goes to volunteer moderators
  4. Response times: Aim for <24 hours on flagged content, <1 hour for CSAM
  5. Appeals process: Users can appeal moderation decisions
  6. Transparency: Publish monthly moderation statistics

5. SSL/TLS Certificate Monitoring

Why This Matters

Expired or invalid SSL certificates break trust and prevent secure connections.

Tools

SSL Labs Server Test

  • URL: https://www.ssllabs.com/ssltest/
  • Purpose: Comprehensive SSL/TLS configuration analysis
  • Use Case: Verify proper SSL setup, identify vulnerabilities
  • Frequency: After any server changes, quarterly reviews

SSLTrust Certificate Checker

Best Practices

  • Use Let’s Encrypt for free SSL certificates (auto-renewal)
  • Set up expiration alerts (60 days, 30 days, 7 days before expiration)
  • Monitor for certificate revocation
  • Verify HTTPS is enforced site-wide

6. Vulnerability Scanning

Free Website Vulnerability Scanners

OWASP ZAP (Zed Attack Proxy)

  • Type: Open source security scanner

  • Use Case: Scan user-uploaded files before storing
  • Integration: Queue system for rate-limited scanning

ClamAV

  • Type: Open source antivirus
  • Cost: Free
  • Deployment: Self-hosted
  • Use Case: Real-time file scanning on upload

File Upload Security Practices

  1. Restrict file types: Only allow necessary formats (images, PDFs)
  2. Scan before storage: Never store unscanned files
  3. Separate storage: Store uploads separate from application code
  4. Filename sanitization: Remove dangerous characters
  5. Size limits: Prevent DOS attacks through large uploads
  6. Access control: Require authentication for sensitive uploads

    • TLD variations (.com vs .org vs .net)

Brand Protection

10. Incident Response Plan

When Something Goes Wrong

Detection
