Understanding Firewalls and its Types

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 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. Of late, with the increased number of hackers at loose, trying to steal the information for their malicious gains, the firewall solutions for small businesses as well as the big corporations have become more crucial than ever. At VRS Tech, we provide an exhaustive firewall network security system in Dubai for every business and domestic use for a secure IT environment.

Firewall is a network device that acts like a barrier between the incoming and outgoing traffic across the network. The firewall network security blocks the computer attacks or prevents further spreading of it. The network can be at safety from the attacks trying to intrude into the network and attempting to gain access to the valuable data present in the system. A network security firewall is essential for the network to be safe.

Packet filtering firewall

The packet filtering firewall blocks the traffic following a set of firewall rules, based on the IP protocol, IP address or port number. This firewall allows web-based traffic into the network and so intrusion prevention system is essential to deal with the web traffic. The intrusion prevention system does the job of differentiating the authentic from unauthentic web traffic and blocks or allows it in.

Among the packet filtering firewalls, the stateful firewalls are more powerful since the stateless firewall cannot make out if the detected packet allowed in and the packet that is disguised are different. The stateful firewall comes with an active and defined firewall management by recognizing the traffic that is part of the established outbound connection.

Deep packet inspection firewall

The deep packet inspection firewall offers security against application level attacks by examining the data in the packets entering the network. The deep packet inspection firewall offers security to some extent but does not examine the whole packet, missing some kinds of attacks. This firewall functions similar to the intrusion prevention system.

Application-aware firewall

The application-aware firewall is capable of adapting to the latest innovations of software and hardware by understanding any kind of network insecurity as per the present day’s changing needs. This firewall detects all kind of network traffic and provides granular traffic at the application level usage like Facebook, Twitter etc. in comparison to the traditional firewalls which need a separate appliance to perform the duty.

Ever since its inception, internet has gained so much of importance and popularity which, evidently, will continue so long as the internet exists. As much good it can do in our day to day lives, it can be unsafe too. It is through the internet that unsafe things travel, finally causing insecurity to our computer networks. The world has witnessed many cases of cyber insecurity where hackers or intruders have taken unfair advantages of the limitless use one could make of the internet. Certainly, with harmful tools, they began to steal sensitive data, send virus or demand a huge sum of ransom by encrypting all the important files. None, be it an individual or a big or small sized business could afford to fall into such an unsafe zone. So the right decision would be to look for ways to have well-protected computers.

firewall network security

There have come into existence security measures into the market with many security companies and providers coming up to offer. Anti-virus is the most common type of software intended to secure your computer from virus attacks. Anti-virus would not be enough but in addition a firewall network security should be installed to protect the overall network and beef up the security.

What is anti-virus?

An anti-virus is software that is intelligent enough to prevent, search for, detect and remove viruses and other malicious software from the computer, disallowing further spread-out of the virus aiming to harm the computer. Anti-virus detects and removes the virus which has already gained access.

What is a firewall?

A firewall is a kind of network security which blocks the incoming and outgoing traffic. In most plain terms, a firewall network security system blocks malicious programs or websites from gaining access to the network but gives way to the right and authentic programs to pass through the network. This way, all the harmful programs, emails, websites can be barred from causing threats to the computer’s important files, data and programs.

Just synonymous to how a firewall prevents fire from spreading out across a building; a network firewall prevents threats from entering your network and spreading it to the other computers.

Why a firewall protection should be employed in addition to anti-virus?

The loopholes in the security should not be incentives for insecurity in the network and so one should consider, why anti-virus is not enough. An anti-virus can handle the detection and removal of the virus, infecting the computers. As a noticeable fact, every day new sorts of virus are being crafted and it may take a while for the anti-virus company to update the anti-virus software program. Instead a firewall can strictly create a blockade for any kind of virus attempting to infiltrate your computer. With a firewall installed, the harmful dangers of network infiltration can be kept at a distance.

Installation of both anti-virus software and the firewall network security is the ideal security measure.
