those procedures and policies because they should always be improved and that’s way
we would believe they got the quite good and not the best ones.

Some researchers would suggest

that we should try to avoid the
hacker’s tools getting remotely

connected to our devices. The

recommended way to do so is to
set up your Firewall – either being

software or hardware by its
configuration. Through our

research, we would find some
sources that would claim we

should follow the quite good

practice of disabling the inbound connections within our Firewall protection. In other
words, those researches would indicate that most of publicly available hacking tools

would use our inbound ports in order to obtain the access to our devices. If we block

those connections – we could reduce the risk from being hacked. In addition, we would
get the information that the entire web traffic could get transferred from inbound to

outbound ports and if we do so – we should count on less threatening network’s
communications. On the other hand, if you use some messenger tool for – let’s say –

chatting purposes – you should define its inbound port being opened because in
opposite – your messenger would not work at all. Well, let’s say that we have defined

some inbound port for the messenger communications and we have assured that we

could take advantage over that tool. In such a case, the hackers could try to exploit that
vulnerability attempting to access your computer and the entire network through that

port. Finally, you would agree that configuring the network’s traffic is the quite trickery
job and it seeks a lot of knowledge to get obtained.

One more suggestion we could make regarding the secure network’s traffic is that we

should try to get the difference between public and private IP address. The private IP
address is the IP address that would belong to your physical device, while the public IP
