Security Checklist for Running a Safe WebBoardRunning a WebBoard (online message board or community forum) requires more than encouraging good conversations — it requires continuous attention to security. A safe WebBoard protects user data, prevents abuse, maintains uptime, and preserves the reputation of your community. Below is a comprehensive, practical security checklist organized into key areas: preparation, platform and code, authentication and access control, content moderation and abuse prevention, data protection and privacy, infrastructure and network, monitoring and incident response, and ongoing maintenance.
Preparation & Risk Assessment
- Define security goals and acceptable risk. Identify what “safe” means for your community: confidentiality of private messages, resilience against spam, legal compliance (e.g., GDPR), etc.
- Inventory assets. List software components (forum software, plugins), hosting environments, databases, backups, SSL certificates, and admin access points.
- Identify threats and threat actors. Consider spammers, credential-stuffing bots, DDoS attackers, insiders, and supply-chain risks from third-party plugins.
- Establish roles & responsibilities. Document who manages servers, moderators, backups, and incident response.
Platform & Code Security
- Use well-maintained, actively supported forum software with a strong security track record (e.g., Discourse, phpBB, Flarum, NodeBB), or a vetted custom solution.
- Keep all software up to date. Apply security patches to forum software, plugins, frameworks, and the OS as soon as feasible.
- Minimize plugin usage. Each plugin increases attack surface; only enable necessary, trusted plugins.
- Review third-party code for known vulnerabilities and subscribe to their security announcement channels.
- For custom code, follow secure coding practices: input validation, output encoding, parameterized queries, and secure error handling. Use static analysis and code reviews.
Authentication & Access Control
- Enforce strong passwords (minimum length, complexity) and block commonly used passwords.
- Implement multi-factor authentication (MFA) for administrative and moderator accounts.
- Use role-based access control (RBAC): separate duties (admins, moderators, devs) and give least privilege.
- Rate-limit login attempts and block IPs or accounts after repeated failures to mitigate credential stuffing.
- Consider support for OAuth/OpenID Connect (e.g., Google, Apple) to delegate secure authentication.
Content Moderation & Abuse Prevention
- Deploy automated spam filters (Akismet, StopForumSpam, or built-in solutions) and honeypots for bots.
- Use captchas (reCAPTCHA v3 or hCaptcha) selectively — for registrations, posting from new accounts, or suspicious activity.
- Implement moderation workflows: reporting tools, queues for flagged content, and escalation policies.
- Enforce community guidelines with clear terms of service and a visible moderation policy.
- Keep logs of moderation actions (edits, deletions, bans) for accountability.
Data Protection & Privacy
- Encrypt sensitive data at rest (database-level or full-disk encryption) and in transit (TLS 1.2+). Use HTTPS everywhere.
- Store passwords using a strong hashing algorithm (bcrypt, Argon2) with appropriate work factors.
- Minimize data collection: only store what’s necessary, and define retention periods.
- Implement secure deletion practices for removed accounts/content where required.
- Provide users with privacy controls (account deletion, export of their data) to comply with regulations like GDPR.
- Maintain a clear, accurate privacy policy.
Infrastructure & Network
- Use a reputable hosting provider with security features (isolated VMs/containers, private networks).
- Place the web application behind a Web Application Firewall (WAF) and, if appropriate, a CDN that offers DDoS protection.
- Segment networks: separate database servers from web servers; use private subnets and strict security groups.
- Disable unnecessary services and ports; follow the principle of least exposure.
- Use secure, non-default ports for management interfaces and SSH. Require SSH keys and disable password SSH where possible.
- Rotate credentials (API keys, database passwords) regularly and use secrets management tools.
Monitoring & Logging
- Enable centralized logging for web servers, application logs, authentication events, and moderator actions.
- Retain logs securely for a defined period and protect them from tampering.
- Monitor for anomalous activity: spikes in traffic, repeated failed logins, mass posting, or sudden moderator changes.
- Use intrusion detection systems (IDS) and host-based monitoring to detect compromise.
- Establish alerting thresholds and integrate with on-call tools (email, SMS, Slack, PagerDuty).
Incident Response & Recovery
- Create an incident response plan covering detection, containment, eradication, recovery, and post-incident review.
- Maintain recent, tested backups with offsite copies. Periodically test restores.
- Predefine communication templates and legal/PR contacts for larger breaches.
- Revoke compromised credentials and rotate keys immediately after suspected breaches.
- Conduct a postmortem to identify root causes and update controls.
Backup & Business Continuity
- Automate encrypted backups of databases and critical assets. Store backups in multiple locations.
- Test backup restoration at least quarterly.
- Keep a read-only snapshot of critical data to support investigations.
- Document disaster recovery steps and prioritize services for restoration.
API, Integrations & Third-Party Services
- Vet third-party integrations for security practices and least privilege access.
- Use API rate limits, authentication tokens, and scopes. Rotate API keys regularly.
- Validate and sanitize incoming webhook payloads and use HMAC signatures to verify authenticity.
Client-Side Security & Privacy
- Set secure HTTP headers: Content-Security-Policy (CSP), X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Strict-Transport-Security (HSTS).
- Protect against XSS by encoding user content, using secure templating libraries, and applying CSP.
- Use SameSite and Secure flags for cookies; avoid storing sensitive tokens in insecure storage.
- Limit user-uploaded file types and scan uploads for malware.
Legal, Policy & User Education
- Publish clear Terms of Service and Community Guidelines; include acceptable use, prohibited content, and appeals process.
- Provide clear reporting mechanisms and reply timelines for user reports.
- Educate moderators and admins on phishing, social engineering, and safe handling of user data.
- Maintain a plan for lawful requests (DMCA, subpoenas), documenting how you’ll respond and who handles them.
Ongoing Maintenance & Testing
- Schedule regular vulnerability scans and periodic third-party penetration tests.
- Run dependency scanning (SCA) on your codebase and plugins to detect vulnerable libraries.
- Keep an internal security checklist and review it after major feature releases.
- Hold regular security reviews and tabletop incident response exercises.
Final quick checklist (actionable)
- Enable HTTPS and HSTS.
- Require strong passwords and enable MFA for admins.
- Keep software and plugins updated.
- Use a WAF and DDoS protection.
- Encrypt data at rest and in transit.
- Backup regularly and test restores.
- Implement spam filters, captchas, and moderation workflows.
- Log and monitor authentication and moderation events.
- Perform regular vulnerability scans and penetration tests.
Keeping a WebBoard secure is continuous work: run audits, listen to your community’s concerns, and adapt controls as threats evolve.
