Proxy Firewall
A firewall
is a network security device that separates a trusted internal network from an
external network that is considered untrusted, such as the Internet. It
regulates incoming and outgoing network traffic based on pre-configured
security rules. Firewalls play a central role in protecting networks from
unauthorized access, malicious activity, and potential threats, and can exist
as hardware, software, Software as a Service (SaaS), or a public or private
(virtual) cloud.
Firewalls
inspect network packets to implement security policies, effectively preventing
unauthorized users and potentially harmful data from entering or leaving the
network. A firewall primarily acts as a gatekeeper, checking every network
packet and deciding whether to allow or block the packet based on
pre-configured rules. This ensures that only traffic that is deemed safe and
legitimate passes through the firewall.
In addition
to these core functions, today's next-generation firewalls (NGFWs) have many
other features to improve network security. These include deep packet
inspection, application visibility and control, intrusion detection and
prevention, malware protection, URL filtering, and more.
Types of
Firewalls
Packet Filter Firewalls
These
firewalls inspect all data packets that pass through them and filter them based
on parameters such as source and destination IP addresses, port numbers, and
protocol types. These firewalls are relatively simple and inexpensive, but
because they cannot inspect the contents of packets, they are less effective
against complex attacks.
Proxy Firewall
A proxy
firewall is an early type of firewall device that acts as a gateway from one
network to another for specific applications. By preventing direct connections
from outside the network, a proxy server can provide additional functionality
such as content caching and security. However, this can also impact throughput
capabilities and the applications they can support.
Stateful Inspection Firewall A
stateful
inspection firewall is now considered a traditional firewall, and allows or
blocks traffic based on status, port, and protocol. It monitors all activity
from the beginning to the end of a connection. Filtering decisions are based on
both administrator-defined rules and context, using information from previous
connections and packets belonging to the same connection.
