Detailed Description

Security state and connection set for a single IP.

Core state unit of ConnectionLimiter, implementing layered IP-level + fd-level defense:

• activeConnections: concurrent connections from this IP
• connectRate: IP-level connection rate limiter state
• badScore: accumulated risk score (escalation trigger)
• conns: all active connections for this IP (fd -> ConnectionState)

Defense semantics

• activeConnections / connectRate:
  • Protect against connection floods and brute-force
• badScore:
  • Used to escalate defense (disconnect / temporary ban)

Note

• Blacklisting (ban TTL) is managed by ConnectionLimiter globally.
• badScore can be decayed over time or reset after a ban.
