TYPES OF FIREWALLS IN NETWORK SECURITY PPT

Conclusions
With the increased number of threats to networks such as worms, viruses and clever hackers, security can no longer be viewed as an option, even within “private” networks. Securing all equipment, including physical infrastructure equipment such as UPS systems and HVAC s[r]

The bandwidth capacity of a network cable is usually measured in the number of bits or bytes that can be transferred in a second. In modem con- nections, thousands of bits may be sent, with each thousand referred to as a kilobit per second (Kbps). <[r]

Second, because application firewalls typically perform a more detailed inspection of the data, they perform worse than a comparable stateful packet-filtering firewall. By placing the firewall closest to the resources being protected, you reduce the volume of extraneous traff[r]

Firewalls
A firewall is a hardware or software solution implemented within the network infrastructure that contains a set of programs designed to enforce an organization’s security policies by restricting access to specific network resources. In the phys[r]
