However trojans can find another ways to enter the system, so you must use a good internet security product with firewall.

ICMP
Pretty much every protocol used for malicious traffic and Trojans is also used for legitimate traffic. You cannot block all bad traffic just by filtering on protocols. When given that ICMP and HTTP are both allowed, if you have to block one, block ICMP. Choices were: DNS DHCP ICMP HTTP https://library.skillport.com/courseware/cbtlib/TPSY0201/metadata/eng/TPSY0201B.htm?
In computer terms, IPS stands for Intrusion Prevention System. An IPS is a network security device that monitors network traffic and system activity for malicious activity.

If you have a firewall, you should be able to go to your firewall and edit the traffic options, which dictates what programs get Internet access and which ones don't. Edit the protocol for your Internet browser to unblock it.
What protocol is used by web servers and on which port ?
The protocol used for handling TCP traffic through a proxy server is called SOCKS, which means \"Socket Secure\".
Generally traffic exiting a LAN is controlled at the router or firewall by setting rules in the configuration files for the router or firewall restricting what IP addresses traffic can be sent to, what devices outbound traffic can be sent from. You can also set rules controlling what outbound ports, protocols, and services will be blocked or allowed. Generally the best way to configure is "deny all and allow by exception" where all traffic is blocked by default and then rules are inserted to allow exceptions for specific traffic. You would also insert settings into the Access Control List.
Tracing network traffic requires a network monitor, protocol analyzer, or packet sniffer.
