About Port Patrol
Ports flash on screen. You have 60 seconds to identify as many services as you can: FTP, RDP, Elasticsearch, Modbus. How many do you know?
Difficulty: IntermediateTime: 60 sec
How it works
- You have 60 seconds. A port number flashes on screen and you pick its service from four options.
- Correct answers score 10 points on easy ports and up to 20 on hard ones, with a streak counter that lights up after three in a row.
- There are no lives. The round runs until the timer hits zero, then you get a grade from IT Helpdesk up to Network Security Expert.
What you'll learn
- Everyday ports and their services: FTP on 21, SSH on 22, HTTP on 80, HTTPS on 443, and DNS on 53.
- Database ports that should never face the internet: MySQL 3306, PostgreSQL 5432, Redis 6379, MongoDB 27017, and MSSQL 1433.
- High-risk management and data services like RDP 3389, SMB 445, Elasticsearch 9200, the Kubernetes API on 6443, and Modbus 502.
- Why some ports carry a critical risk note, such as Telnet 23 sending credentials in clear text.
