Overview

AngkorSecurity is a comprehensive, production-ready security plugin built for Paper 1.21 servers.
It combines real-time threat detection, automated response, and deep audit logging into a single lightweight plugin — no database required.

Originally built for KrudSMP, a hybrid Java + Bedrock server, it is designed to handle both premium and cracked player environments with full Velocity proxy support.

✨ Features

Brute-Force Protection

• Tracks failed login attempts per IP within a configurable time window
• Automatic lockout after threshold is reached
• Auto-ban IP and/or player on lockout (permanent or timed)
• Configurable attempt limit, lockout duration, and track window

Threat Score System

• Per-IP threat score (0–100) that escalates automatically
• Alert admins at configurable score threshold
• Temporary ban at mid-level threshold
• Permanent ban + Discord alert at high threshold
• Score decays over time when no suspicious activity is detected

VPN & GeoIP Blocking

• Detects VPN, proxy, and Tor exit nodes via ip-api.com
• Optional hosting/datacenter IP blocking
• Country whitelist or blacklist mode (GeoIP)
• Result caching to minimize API calls
• Graceful fallback — allows player through if API is unreachable

OP Tracker

• Detects unauthorized /op and /deop commands
• Auto-deop unknown operators instantly
• Kick player and drop inventory on unauthorized OP
• Periodic background scan for unknown OPs
• Full Discord + in-game alerts

Permission Guard

• Protects sensitive LuckPerms permissions from being granted or revoked
• Configurable protected permission list
• Alert admins on any protected permission change
• Optional auto-cancel of unauthorized permission changes

Gamemode Guard

• Blocks unauthorized creative mode switches
• Auto-kick or auto-ban players who enter creative mode
• Exempt permission node for trusted staff

Session & Alt Detection

• Tracks known IPs per player
• Alerts on login from a new/unknown IP
• Detects alt accounts sharing IPs with banned players
• Detects and logs player name changes

Staff Accountability

• Full staff action tracker with configurable retention
• Anomaly detection — alerts when staff logs in at unusual hours (configurable timezone)
• Suspicious command detection and logging
• All actions stored in a structured audit trail

Discord Webhooks

• Per-category webhooks (security, sessions, permissions, commands)
• Configurable event list — choose exactly what gets posted
• Rich embed-style messages with player name, IP, reason, and timestamp

Lockdown Mode

• /asec lockdown on — instantly kicks all non-admin online players and blocks new joins
• /asec lockdown off — restores normal access
• Admins with angkorsecurity.admin are always exempt

Audit Log & GUI

• Structured in-game GUI (/asec alerts) showing all security events
• Paginated — supports hundreds of entries
• Click any alert to see full detail in chat
• Plain-text audit.log file with auto-rotation

⚙ Other Features

• Jail & Mute system with duration support
• Spam & chat filter protection
• Login rate limiter (max connections per minute per IP)
