Is this the part that's "Easy to understand"
"The first is at the actual packet level (layers 3 and 4 of the OSI
model). The job here is to look for suspicious or malformed packets,
detect port scans, and assess whether or not each packet should be
allowed into the protocol stack. Packets will be analyzed by networking
criteria, for example: formal validity of the packet; direction of the
packet (inbound or outbound); source host and port; destination host and
port; specific packet flags (is this a connection attempt? Does it
belong to an already established connection?)"
It's not that I haven't tried, and I even have a book on TCP/IP, but
that's largely opaque to me.
My users barely understand copy and paste, so this might as well be in
Greek.
Windows just doesn't work very well in protecting people from the
evil-doers out there.
