    Hey guys, for you network security guys, can anyone list as much as they can, different softwares that can protect the 7 layer OSI model? ( I only need the first 4)
    1.Physical Layer
    2.Data link layer
    3.Network Layer
    4.Transport Layer

    Like i just need vendor names or software names to protect these 4 layers (and each software has to be different).. its for a uni assignment so it'll be great if u guys can help me out!!! thanks alot!!!!!!!!!

    Software, at the physical layer??

    I would have thought your more likely to be looking at hardware here.

    So, mainstream firewall providers - people like Cisco, Sonicwall, Zyxel, HP, Nokia
