Which of the following describes a firewall?
Detailed Solution. The correct answer is Preventing unauthorized access. A firewall is a kind of security-conscious type of hardware or software that stays between the computer and our network with a primary task: preventing malicious software from reaching us.
A firewall is a network security device that monitors incoming and outgoing network traffic and permits or blocks data packets based on a set of security rules.
Which of the following best describes a firewall? It is a combination of hardware and software that controls the flow of incoming and outgoing network traffic.
What is a firewall? hardware or software system that prevents unauthorized access to or from a network. - used to separate a trusted network from an untrusted network. - basically act like a filter and stops untrusted network traffic or packets. It protects the network from external attacks.
- Physical Barrier: A firewall does not allow any external traffic to enter a system or a network without its allowance. ...
- Multi-Purpose: A firewall has many functions other than security purposes. ...
- Flexible Security Policies: Different local systems or networks need different security policies.
What do firewalls do? Firewalls provide protection against outside cyber attackers by shielding your computer or network from malicious or unnecessary network traffic. Firewalls can also prevent malicious software from accessing a computer or network via the internet.
A firewall is a security system designed to prevent unauthorized access into or out of a computer network. Firewalls are often used to make sure internet users without access are not able to interface with private networks, or intranets, connected to the internet.
Which statement is true of firewalls? They protect against external access, but they leave networks unprotected from internal intrusions.
The correct answer is It is unable to permit legitimate communication to pass. A firewall is a network security device/software that monitors incoming and outgoing network traffic and permits or blocks data packets based on a set of security rules.
Which of the following best describes a host-based firewall? A host-based firewall is a software firewall that protects a single endpoint device.
Which of the following are true about firewalls?
Firewalls are filters network traffic which follows a set of rules and can either be used as hardware or software device. They are often categorized as network or host-based firewalls. Network firewall filter traffic between two or more networks while host networks run on host computers.
The firewall rules block all other traffic. These filtering rules on the firewall are called Access Control Lists, or ACLs. The firewall scans incoming and outgoing network traffic, and it compares that traffic to the rules you've defined. Then it decides whether the traffic should be allowed or rejected.
A firewall can help protect your computer and data by managing your network traffic. It does this by blocking unsolicited and unwanted incoming network traffic. A firewall validates access by assessing this incoming traffic for anything malicious like hackers and malware that could infect your computer.

What are two types of firewall? and software firewall.
A firewall keeps track of the established connections passing through it. A(n) learns what is "normal" on the network and can react to abnormalities even if they're not part of the signature database.
The most common firewall types based on methods of operation are: Packet-filtering firewalls. Proxy firewalls.
Which of the following statements best describes a stateful packet inspection firewall? It can keep track of the status of the connection in addition to examining each packet.
Which statement best describes network security?
Network security means everyone has access to the information the network is not compromised and only a handful of people are authorized to use it.
Packet filtering firewalls are one of the earliest and simplest forms of the modern firewall.
Which of the following best describes a network authentication system? c. A system that sits at the border of a network and allows or rejects traffic coming into or out of the network based on a set of pre-written rules.
Which of the following is another name for a firewall that performs router functions? A firewall performing router functions is considered a screening router. A screening router is the router that is most external to your network and closest to the internet.
Which of the following is the best description of a key (that is used in encryption/decryption)? b. A key is the data to be protected from eavesdroppers during transmission from sender to receiver (like a social security number, credit card number, username and password, etc.)
Which of the following types of proxies can be used for web filtering? Transparent proxies are located between a user and the internet, and they can redirect requests without changing them. These can also be used for web filtering. Reverse proxies can be used for caching and authentication.
