Advantages and Disadvantages of Firewall

Any computer that connects to an internet connection is vulnerable to attacks. Some computers can be more vulnerable than the other. In order for protecting against them there must be a system that should act as a gateway between the user and the internet. 

In this article, I will be illustrating the Advantages and Disadvantages of Firewall | Drawbacks and Benefits of Firewall. Finally from this article, you will know the pros and cons of using firewall.

Advantages of Network Firewall :

  1. Monitors network traffic
    A network firewall monitors and analyzes traffic by inspecting whether the traffic or packets passing through our network is safe for our network or not. By doing so, it keeps our network away from any malicious content that can harm our network.
  2. Halt Hacking
    In a society where everyone is connected to technology, it becomes more important to keep firewalls in our network and use the internet safely.
  3. Stops viruses
    Viruses can come from anywhere, such as from an insecure website, from a spam message, or any threat, so it becomes more important to have a strong defense system (i.e. firewall in this case), a virus attack can easily shut off a whole network. In such a situation, a firewall plays a vital role. 
  4. Better security
    If it is about monitoring and analyzing the network from time to time and establishing a malware-free, virus-free, spam-free environment so network firewall will provide better security to our network.
  5. Increase privacy
    By protecting the network and providing better security, we get a network that can be trusted. 

Disadvantages of Network Firewall :

  1. Cost
    Depending on the type of firewall, it can be costly, usually, the hardware firewalls are more costly than the software ones.
  2. Restricts User
    Restricting users can be a disadvantage for large organizations, because of its tough security mechanism. A firewall can restrict the employees to do a certain operation even though it’s a necessary operation.
  3. Issues with the speed of the network
    Since the firewalls have to monitor every packet passing through the network, this can slow down operations needed to be performed, or it can simply lead to slowing down the network.
  4. Maintenance
    Firewalls require continuous updates and maintenance with every change in the networking technology.  As the development of new viruses is increasing continuously that can damage your system.
