I'm no security expert, but I would suggest that a benefit of
'Personal' firewalls is the provision of a simple, systematic way of
restricting access to services. Yes, many apps offer some way of doing
this, but remembering each one's different method of doing this can be
a headache. I suppose one really should, for maximum security, but I
think there's still benefit in a simpler, consistent system.
Additionally, not all apps do this the same way; for example, sshd can
be configured to bind to a specific IP address, but what if the address
is unknowable in advance? Can it be limited to a specific interface,
as can be accomplished with a firewall? Even if the answer is yes, my
point about simplicity remains.
I may be off base here; I'm just expressing my (limited) understanding
of the issue.
