The firewall function that allows legitimate traffic entry into a network is called "packet filtering." This process involves examining incoming packets and allowing or blocking them based on predefined security rules, such as source/destination IP addresses, port numbers, and protocols. Additionally, stateful inspection enhances this function by tracking active connections and making decisions based on the state of the traffic. Together, these mechanisms help ensure that only authorized traffic is permitted while unwanted or harmful traffic is blocked.
The firewall determines if network traffic should continue on to its destination or be stopped.True (Correct!)False
A network firewall prevents unlawful network access to your website. However, most website attacks are perpetrated via ports that must be kept open to allow legitimate HTTP, HTTPS and FTP traffic. This is where an application firewall is important because it inspects all the traffic and separates legitimate traffic from attack attempts against your website.Companies as Incapsula.com provides every web application, regardless of its size, with enterprise-grade Web Application Firewall, ensuring that the website's web application is safe and available.A web application firewall helps protect a website from illegitimate traffic
The purpose of the Sonicwall firewall is to provide security for the network and to monitor the traffic entering and exiting a network. This prevents malware and intrusions.
The tool used to regulate the traffic that traverses into or out of a network is known as a firewall. It serves as a security barrier, scrutinizing the network traffic based on predefined rules, and blocks or permits data packets accordingly. It's an essential component in maintaining the security and integrity of a network.

A firewall can be configured to block ICMP packets, but it depends on the specific rules set by the network administrator. By default, many firewalls allow ICMP traffic for essential functions like ping and network diagnostics. However, to enhance security, some firewalls may restrict or block certain types of ICMP packets to prevent potential attacks or network scanning. Ultimately, whether ICMP packets are blocked or allowed is determined by the firewall's configuration.
A router is a device that routes all traffic to and from your network. A router functions by forwarding packets of data between computer networks.

Traffic analysis is a method used by attackers to monitor and analyze network traffic to gather information about its patterns, volume, and behavior. This can help attackers identify vulnerabilities in the network and plan future attacks more effectively. It can also be used for legitimate purposes, such as optimizing network performance and security.
A firewall intercepts and controls traffic between networks with differing levels of trust. It is part of the network perimeter defense of an organization and should enforce a network security policy.
