A firewall is the tool that blocks ports, programs, or any other network traffic from incoming or outgoing connections.

A firewall controls outgoing communications by inspecting data packets leaving a network and applying predefined security rules to determine whether to allow or block them. It can filter traffic based on criteria such as IP addresses, port numbers, and protocols. By doing so, the firewall helps prevent unauthorized data transmission and protects sensitive information from being sent outside the network. Additionally, it can log outgoing traffic for monitoring and analysis.
The list of rules that a firewall uses to determine which traffic to block is called an "Access Control List" (ACL). An ACL defines the criteria for allowing or denying network traffic based on attributes such as IP addresses, port numbers, and protocols. Firewalls apply these rules to filter incoming and outgoing traffic, ensuring that only authorized communication is permitted while unauthorized access is blocked.
Protesters can block traffic during a demonstration, but it is illegal and can result in consequences such as arrests or fines. It is important for protesters to find lawful ways to express their views without disrupting public safety.
A firewall can restrict access to a computer network by monitoring and controlling incoming and outgoing network traffic based on predetermined security rules. It can block unauthorized access attempts from external sources while allowing legitimate traffic through. By setting specific rules, such as allowing only certain IP addresses or protocols, a firewall helps protect the network from threats and unauthorized users. Additionally, firewalls can provide logging and alerting features to notify administrators of suspicious activities.
Protestors do not have the legal right to block traffic, as it can be considered a public safety hazard and a violation of traffic laws.
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?
probably the best solution is to use a firewall that notifies you about outbound connections and to use a firewall between you and the internet that is not part of your computer on which you block all unnecessary outbound ports you may also install an ids that can tell you when outbound traffic on a port is abnormally high you might even be able to configure an ips to block the traffic

Peer Guardian 2 was released in March 2005 in beta format. It is computer software made by Phoenix labs for Microsoft Windows to block both incoming and outgoing connections.
