What is a Layer 7 firewall?
Layer 7 Firewalls (Application Firewalls) Layer 7 lets you sort traffic according to which application or application service the traffic is trying to reach, and what the specific contents of that traffic are.
How is IP spoofing detected?
Since a lot of the networks do not apply source IP filtering to its outgoing traffic, an attacker may insert an arbitrary source IP address in an outgoing packet, i.e., IP address spoofing. … A proposed detection scheme is based on an analysis of NetFlow data collected at the entry points in the network.
What is the main purpose of a firewall?
Its purpose is to control what traffic is allowed to traverse from one side to the other. As the most basic level, firewalls can block traffic intended for particular IP addresses or server ports.
Can firewall be hacked?
Firewalls are essential for internet security, since they prevent anyone from the outside to access the internal network, and possibly sensitive data. However, firewalls are no panacea. In some cases, malicious hackers can still attack a vulnerable web application that is hosted behind a firewall.

What are the two main types of firewall?
This post reviews two primary firewall types – basic traffic scanning devices and interactive layer-inspecting machines. The kinds of firewall technology currently on the market: packet filtering, circuit-level gateway, stateful inspection, application-level gateway, multilayer inspection, and UTM.
What is the most secure type of firewall?
Proxy FirewallsProxy Firewalls (Application-Level Gateways) As the most powerfully secure choice available, proxy firewalls serve as an intermediary where source computers connect to the proxy instead of the destination device.
