For getting job in computer networking you have to be CCNS or MCSE certified. Try to gain knowledge and then go for it. Give your 100% otherwise not.

Tiny packets can slip through a firewall, where there are rules for sting comparisons.

but the thought is so split up/fragmented, worm is in one packet, .exe is in an other, therefore it doesen’t match the rule set and allowed by the firewall.

I'm using arpspoofing techniques, but it's frustrating, I'm trying to understand how it works better. I can forward packets from one IP to me, but how do you do a whole subnet? Btw, what’s the common use for this? I’m using arpspoofing techniques, but it’s frustrating, I’m trying to be with you how it works better. I can forward packets from one IP to me, but how do you do a total subnet?

This can be achieved in three ways - Physical Security - Application Security - Hardware Security. Physical trying to limit physical access to a computer or networking devices. This can be done by housing critical devices in areas that few people have knowledge, requires keys, or smart card access. Hardware security reflects on networking devices such as routers and firewalls that have builtin virus scanners or access rules. Access rules are a defined list of both allowed and not allowed activities or programs. Similar to a bouncer at a bar, they inspect everything that goes in or out. Some also act as honey pot which pretends to be computer or server and will act as a scout that will alarm the adminstrator of possible threats. Some devices are advanced enough to offer hardware based encryption or reroute traffic when a threat is found. Application Security mostly deals with access permissions or group policies, encryption and programs located on a computer or server. Firewalls , antispam, spyware or virus scanners are the common tools that will be found at this level. Along with having a physical firewall scanners and encryption, application based solutions are needed because one level miss a threat. For example if a threat originates from within a network, considerable damage could of occured before its isolation with out the additional application layer. Group policies and access permissions are in some ways similar to a firewall. Not only do they have a list of which activities or programs are permitted, but depending on restrictions, they can deny access to files or certain tasks on a computer such as changing the system date or installing software. Finally, a true secure network environment is totally isolated meaning no network connection or physical access that simple. But that's not practical so have these three layers is must.

Physical trying to limit physical access to a computer or networking devices. This can be done by housing critical devices in areas that few people have knowledge, requires keys, or smart card access.

Hardware security reflects on networking devices such as routers and firewalls that have builtin virus scanners or access rules. Access rules are a defined list of both allowed and not allowed activities or programs. Similar to a bouncer at a bar, they inspect everything that goes in or out. Some also act as honey pot which pretends to be computer or server and will act as a scout that will alarm the adminstrator of possible threats. Some devices are well ahead enough to offer hardware based encryption or reroute traffic when a threat is found.

Application Security mostly deals with access permissions or group policies, encryption and programs located on a computer or server. Firewalls , antispam, spyware or virus scanners are the common tools that will be found at this level. Along with having a physical firewall scanners and encryption, application based solutions are needed because one level miss a threat. For example if a threat originates from within a network, considerable hurt could of occured before its isolation with out the additional application layer.
Group policies and access permissions are in some ways similar to a firewall. Not only do they have a list of which activities or programs are permitted, but depending on restrictions, they can deny access to files or particular tasks on a computer such as changing the system date or installing software. Finally, a right secure network environment is really isolated importance no network connection or physical access that simple. But that's not practical so have these three layers is must.
