IDS Rule References
5 IDS / security rules reference TCP port 3535. Treat that number as context, not a danger score. Many detection rules are written against groups of ports rather than one service, web ports especially, so common web alternate ports inherit large counts while genuinely sensitive services can show few rules or none. Presence in IDS rules does not mean traffic on this port is malicious.
Rule categories (top 3): default-login-attempt (3), suspicious-login (1), attempted-dos (1).
