A popular computer network publication stated at one time that the enterprise firewall was dead. It boldly stated that the exterior firewalls of the organization should be torn down and replaced with host-based firewalls instead. Is this insane, or is it the best new practice in security management? Explain your answer.
A host based firewall is employing the protection on every VM/ machine on the network. Network based firewall is employee on the top of cloud network. In case of host based firewall , if the intruder was able to find out the security vulnerability then he can get all privilages of that machine. Where as in the case of network based firewall its difficult to access the internal VM because the machine and firewall are separate. Also it is very much difficult to portray the traffic of network firewall.
Hence network based firewall with efficient security techniques in force is more better than a host based firewall. its better to have both the firewalls in force to provide strong protection.
