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.

Does The firewall determines if network traffic should continue on to its destination or be stopped?
The firewall determines if network traffic should continue on to its destination or be stopped.True (Correct!)False
What is web application firewall?
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
How can a firewall be used to restrict access to a computer network?
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.
What is the purpose of a sonicwall firewall?
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.
What is the name of the tool used to control the traffic that is entering or leaving your network?
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.
When trying to protect your network you should create your secure network based on?

Does a firewall block ICMP packets?
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.
What device routes all traffic to and from your network?
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.
Which mechanisms is most often used in firewall rules to allow traffic on to the network?
Port Numbers
What is traffic analysis?
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.
How does a firewall effectively control traffic?
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.
