Shields UP!! — Service Ports Probe

Port Authority Edition – Internet Vulnerability Profiling
by Steve Gibson, Gibson Research Corporation.

Determine the status of your
system's first 1056 ports

This Internet service ports "grid scan" determines the status — Open, Closed, or Stealth — of your system's first 1056 TCP ports.

32 ports, represented by each horizontal row, are probed as a group. The results are posted as the next set of ports are probed.

During off-peak hours the entire scan requires just over one minute.

For guaranteed accuracy, the scanning time will increase during peak usage when many people are sharing our scanning bandwidth.

A scan of a stealthed system is up to four times slower since many more probes must be sent to guarantee against Internet packet loss.

The test may be abandoned at any time if you do not wish to wait for the scan to finish.

You may hover your mouse cursor over any grid cell to determine which port it represents, or click on the cell to jump to the corresponding Port Authority database page to learn about the port's specific role, history, and security consequences. (Depress SHIFT when clicking to open new window and allow unfinished test to continue.)
