Understanding Firewalls

• The firewall in simple terms is a
  barrier set to restrict the flow of website
  traffic to or from a network. Now, the barrier
  could be software or hardware alone or could be
  the combination of both to achieve the results.
  The entire flow of information should pass
  through the firewall Solutions in form of packets
  and blocks. Only the data that meets the criteria
  of the firewall settings enter into the network.
  The firewall, in a nutshell, stops the
  unauthorized access into a secured network.

At VRS Tech, we provide an
exhaustive firewall network security system in
Dubai for every business and domestic use for a
secure IT environment. Though the primary goal of
the firewall is to restrict the internet traffic
flowing into the network and from the network,
there are five different types of firewalls that
are deployed based on the unique requirement.

Key Points about how do the firewalls function?

• They are a single block point where the filtering
  and auditing of the network traffic take place.
• The functionality of the firewall is more
  comparable to the TCP/IP layers.
• As there are different types of firewalls
  existing today, the type of firewall that suits
  your type of industry is determined by the
  experts in the field.
• The next step, however, is to identify where to
  place the firewall.
• Once the firewall is placed, the job is far from
  being over. The regular auditing of how the
  firewall activity, begins. This is essential
  because there is always a constant fear of newly
  evolved threats attacking the system.

Various types of firewalls

• Network Layer Firewall or Stateful Firewall
• Application Layer Firewalls
• Proxy Firewalls
• Packet Filter Firewalls
• Next-gen Firewalls

7
Network Layer Firewall or Stateful Firewall

• This type of firewall actually
  considers source address, the destination address
  as single IP packets. The Network Layer firewall
  encourages the particular set of IP addresses
  that need to be blocked as they route the traffic
  directly through them. Due to this feature, they
  tend to be extremely fast and more transparent to
  the end users.

8
Application Layer Firewalls

• These are more elaborate in
  nature. These types of firewalls host the proxies
  and perform an in-depth analysis of all the
  network traffic that passed through it. These
  types of firewalls are not as transparent as the
  Packet firewalls. These instead are used as the
  network address translators as they encrypt the
  actual address after having passed through the
  application.

9
Proxy Firewalls

• These firewalls due to the level of
  filtering of the network traffic they perform are
  extremely slow. They offer more security than any
  other form of firewalls. In the proxy firewalls,
  the endpoint computers establish a connection to
  the proxy and mask the actual address of the
  initiator. This makes it difficult for the
  attackers to directly target the system.

10
Packet Filter Firewalls

• These firewalls are usually
  deployed at routers and switches where the data
  packets are compared to the predefined criteria.
  In case of the packets and IP addresses of the
  port number do not match, they are excluded from
  the list of others entering the network.
• Next-gen Firewalls These are the most recent
  type of firewalls which integrate both the packet
  filter firewalls and the network layer firewalls.
