Note
Suppose Mark is the Network Security Engineer for ABC Company. He is asked by his manager to create a security policy in the Firewalls so that their internal network ABC_INTERNAL(172.16.0.0/24)may be able to access the DNS service from the server DNS_SERVER(192.168.1.5). NAT rule already exists for the Network. How will Mark create the security policy in the Firewalls?
Source: ABC_INTERNAL(172.16.0.0/24), Destination: DNS_SERVER(192.168.1.5), Service: HTTP(80), Action :Accept
Source: ABC_INTERNAL(172.16.0.0/24), Destination: DNS_SERVER(192.168.1.5), Service: DNS(53), Action :Accept
Source:Any, Destination: ABC_INTERNAL(172.16.0.0/24), service DNS(53), Action :Accept
Source: ABC_INTERNAL(172.16.0.0/24), Destination: DNS_SERVER(192.168.1.5), Service: HTTP(80), Action :Drop

Suppose Sally is the Network Security Engineer for ABC Company. She is asked by her manager to create a security policy in the Firewalls so that their internal network ABC_INTERNAL(172.16.0.0/24) may be able to access the SMTP(25) service from the server MAIL_SERVER(192.168.1.15).NAT rule already exists for the network. How will Sally create the security policy in the Firewalls?
Source: ABC_INTERNAL(172.16.0.0/8),Destination: MAIL_SERVER(192.168.1.5), Service: SMTP(25), Action :Accept
Source:ABC_INTERNAL(172.16.0.0/16), Destination:MAIL_SERVER(192.168.1.15), Service: SMTP(25), Action :Accept
Source:ABC_INTERNAL(172.16.0.0/24), Destination:MAIL_SERVER(192.168.1.15), Service:POP3(110), Action :Accept
The security of the Firewalls is a very important aspect.
