Protecting your business web link has become essential, more than ever.
Its hard to imagine a day without the Internet or devices capable of interacting with it.
Tech giants like Google and Facebook have also suffered from such theft.
All thanks to modern advancements thatfirewallshave been introduced to protect against digital threats.
They are designed to safeguard devices and valuable data by monitoring and controlling connection traffic incoming and outgoing.
However, hackers and their threats are evolving as we speak.
Therefore, firewalls need to be smarter as well to face new challenges.
Are all firewalls the same?
No, all firewalls are not built the same.
Each one of them has some pros and cons and applicability, but both are indeed important fornetwork protection.
So, lets jump straight to know them!
What is a Stateful Firewall?
Stateful firewalls are capable of monitoring all aspects of data pipe traffic, including their communication channels and characteristics.
Now, what do thesecontextandstatemean in the language of internet connections?
Next, the connection receives the flag SYN+ACK by the server.
Until the client reverts with ACK, the connection does not establish.
Benefits
It implies that stateful firewalls keep on analyzing every data packet trying to enter into a connection.
Once the stateful firewall approves a traffic request, it can travel freely inside the connection.
However, stateful firewalls can be vulnerable toDDoS attacks.
The reason behind the same is the increased need for software-internet connection and intense computational power for implementation.
What is a Stateless firewall?
On detecting a possible threat, the firewall blocks it.
There are certain preset rules that firewalls enforce while deciding whether traffic must be permitted or not.
As stateless firewalls are not designed to consider as many details as stateful firewalls, they are less rigorous.
For example, a stateless firewall cannot take into account the complete pattern in which packets are entering.
Instead, it will inspect each packet in isolation.
Consequently, stateless firewalls are susceptible to online attacks spread across different packets.
Which firewall is better Stateful or stateless?
Now comes the interesting part!
In addition, they also have a limited budget in hand.
Hence, stateless firewalls could be a suitable option for you if you run a small business.
It could take a toll on their reputation and money.
Not to mention, they also have a larger inkling and outgoing traffic that needs monitoring.
For them, stateful firewalls could do the talking.
Other scenarios
Some FAQs
No.
A firewall can either be stateful or stateless.
The server forgets everything about the online window or client state.
Due to web applications, HTTP looks virtually like stateful, but in reality, it is stateless.
Windows Firewall (WF) is stateful.
It automatically monitors your connections to ensure only trustworthy data is permitted.
