A network firewall serves as the first line of defense for traffic that comes in and out of the network. The firewall checks the traffic to make sure that it meets the requirements for security that was set by the company, and any unauthorized access will be blocked. Firewall protection has evolved a lot over past few years. Apart from monitoring the internet traffic, the most recent firewall security products have a lot of other features.
What is a network firewall?
A network firewall
works by filtering internet transmission so that only authorized access can
only be allowed. Decisions are based on the policies and rules that were set by
the organization. Just like other areas of technology, network firewalls have
changed a lot over time and are far more complicated when it comes to their
deployment flexibility and efficacy.
What are the types of network firewalls?
1.
Packet Filtering Firewalls – an early kind of firewall network security that
depended on packet characteristics such as the source as well as destination IT
address. Protocol and port of each packet to determine if it must be dropped or
allowed to pass through.
2.
Stateful Inspection Firewalls – this type of firewall
protection adds the ability to check packets that belong to a complete session.
When a session is created, the destination and the source are permitted to
communicate without having to check subsequent packets in that particular
session.
3.
Application layer firewalls – they check the packet
level data and application layer data.
4.
Next-generationfirewalls – the latest firewall technology that adds different capabilities.
It is a deep packet inspection tool that goes beyond protocol/port checks and
blocking to include application level inspection, preventing intrusion, as well
as intelligence from outside the network firewall.
What are the next generation firewall solutions?
The feature strengths will determine the differences between
next generation firewalls. Less than half of the company internet connections
today are secured using next generation firewalls. But this is expected to
increase to 90%. This forecast has led several vendors to exploit the trend in
the firewall market. Many companies too, are expected to seek out IT Support Florence SC.
Juniper Networks – provides a portfolio of firewalls that
cater to mid and large size companies, service providers in the public or
private cloud, as well as hybrid environments.
Palo Alto Networks – claims that a few network firewalls pretend
as next generation firewalls by bringing deep inspection modules onto the
conventional port/protocol based architectures.
Barracuda Networks – allows users to monitor application
usage as well as prioritize network traffic that comes with features such as
WAN optimization and link balancing. They can be deployed on on-premises,
virtual, or cloud scenarios. The can offer protection against exploit patterns and
intrusion attempts at the network layer.
Check Point Software – the network firewall gateway can be improved
through subscriptions to offer advanced and complex malware protection as well
as different threat intelligence feeds.
Cisco – its Adaptive Security Appliance as well as its
FirePOWER services provides Sourcefire IPS, application control, as well as
malware protection.
SonicWALL – offers different firewall related products for
small branches and offices, larger and midmarket enterprises, and offers
integration with the wireless access points, switches, and WAN optimization
products.
Forcepoint – joins different elements and the firewall
product may reach up to 120 gbps and they have a virtualized version.
Fortinet – its FortiGate product is utilized as the firewall
for several service providers, SMBs, and enterprises.
