Network security and firewall have been the most pivotal elements in reference to bringing about the appropriate enforcement and the subsequent deployment of the security policy within the Network connectivity in the organization.
In this particular paradigm, the firewall has been considered as a network security device that constantly monitors both the incoming and outgoing network traffic and in this particular traffic regulation the firewall acts as a barrier between the trusted and the untrusted network system thereby Filtering the data packets ensuring that data which is further transmitted from the source to the other terminal end points happens safely.
Efficacy of the packet filtering methodology
As an analogy, one can understand that Packet Filtering is an expensive component to implement and deploy in the corporate networks. However, one should understand that a packet filtering method of firewall has a very limited level of security as compared to the application or the proxy firewall system
How packet filtering becomes the core activity of the firewall execution?
The packet filtering has been considered as the process of data filtering technique which blocks the untrusted data packets at the source of the network interface itself. This blocking of the untrusted data packets so that the internal network system is kept safe from any malicious intrusions that are bound to occur.
The packet filtering has been considered as one of the core component of the firewall execution program which is specifically designed to safeguard the network system from any untoward intrusions. The packet filtering comprises of three methods of packet filtering mechanism and once configured in the system can predominantly filter the data packets.
- The first method of packet filtering: In the first method, the packet filtering filters only those data packets which adhere to the standard protocol and discarding the other. The first method of packet filtering has been considered the most secured but there are equal chances for some of the legitimate packets to eventually getting dropped.
- The second method of packet filtering: In the second method, the packet filtering drops the data packets which are unsafe and accepting the packets which are safe.
- The third method of packet filtering: In the event that the filter encountering a packet which the firewall is not able to balance between the trusted and untrusted data packets, it queries with the user about the nature of the data packet and probably rejects or accepts based on the user inputs.
The network security firewall have emerged as a solution in itself in reference to providing the finest cyber security in the enterprise network system and in this particular trend VRS Tech have been constantly empowering the security coverage to the network system both internal and external.
