Network layer firewalls examine every incoming and outgoing packet of information and filter out malicious requests by comparing database patterns. This type of firewall acts as a barrier between the private network and the public internet, blocking any suspicious traffic from entering the organization’s system. While this type of firewall is very efficient in blocking malicious requests, it may also inadvertently block some legitimate requests.
On the other hand, application layer firewalls are more intelligent and flexible compared to network layer firewalls. These firewalls inspect requests on a deeper level, employing advanced technologies such as deep packet inspection (DPI) to detect and stop malicious traffic. In addition, application layer firewalls can be configured to allow certain types of requests, such as those relating to remote access, email, or file transfer protocols.
Using both types of firewalls provides an organization with an extra layer of security that can greatly reduce its risk of becoming a cyber-attack victim. Some of the other benefits associated with using a firewall include:
1. Enhances Security on Multiple Levels – A firewall can be used to lock down ports on remote hosts, thus preventing malicious actors from using them to launch attacks. In addition, the firewall can be used to detect and prevent malicious traffic from entering the organization’s network.
2. Proactively Filters Out Malicious Traffic – Firewalls can help distinguish between legitimate and malicious traffic, thus ensuring only the most secure connections are allowed to pass through to the private network.
3. Increases Visibility Of Network Traffic – Most firewalls allow administrators to monitor network traffic to identify malicious traffic and take appropriate action.
4. Enhances Network Performance – Firewalls help to protect organizations’ networks from malicious traffic and by blocking unwanted or unauthorized requests, they can also reduce the load on the network and improve its overall performance.
Overall, using a firewall is an essential step for any organization looking to maintain a secure IT environment. By implementing a firewall, Organizations can protect their networks and critical assets from malicious traffic, unauthorized access, and data breaches. In addition, they can ensure their network remains performant while still protecting against malicious threats.
