  • Privileged ports

    From Richard Tobin@21:1/5 to All on Wed Apr 5 14:49:18 2023
    Traditionally, only root can bind to IP port numbers <1024.

    That no longer seems to be enforced on MacOS, which seems a bit
    surprising.

    Certainly not on all OSes - Windows in particular didn't restrict this.
    Either way, it doesn't really add much at all to security.

    There are perhaps some additional privileges assigned to certain groups?
