Importance And Importance Of Internet Security

Firewall: A firewall is a software or hardware-based network security system that controls the incoming and outgoing network traffic by analysing the data packets and

AVG has an anti-spam application which blocks spammers and scammers as well as a firewall to block hackers, so the user is able to go online purchase items or pay bills (AVG, 2014).

The most effective way to protect your personal information on the internet is to have a strong password. A strong password should consist of a mixture of upper and lower case letters, numbers, and special characters. Ideally you want a unique password made up of at least ten characters for every website you have an account on.

A Virus is a piece of malicious code that has the intent to damage your system.

Antivirus is programming program that outline to make PC gradually in light of the fact that programmer can be take the secret word and furthermore the records can be erase frame desktop and imperative things like video and picture there case about that treats, worms and Trojans.

Firewall is “a computer security program that blocks incoming network traffic based on certain predetermined criteria”. Firewalls have details logs, that can hold a wealth of information about the network to the forensics investigations. The firewall logs can also have details about the hardware failures. Successful/unsuccessful connection attempts, users added on, and any permissions changed. You can also find evidence on the backdoors.

Antivirus software is something we use to protect our computers from viruses .we use software's such as Norton security and MacAfee.

A firewall protects networked computers from intentional hostile intrusion that could compromise confidentiality or result in data corruption or denial of service. It may be a hardware device or a software program running on a secure host computer. It must have at least two network interfaces, one of the network it is intended to protect, and one for the network it exposed

Another thing that you should never do, is use the same password for everything. The problem with using the same password for all your online accounts is that if someone was able to crack that one password, they would have access to everything. So a few things that would help keep your information safe. First you must create different passwords that are at least 14 -16 characters

Anti-virus software was designed to run a specific job of protecting a user’s computer system from any threats obtained from the internet or even files that may be downloaded of the internet or any external source. How it work is by a number of ways first by shielding itself, normally starting off with an anti-virus firewall, so it scans files eliminates threats and informs you if a website is safe or not. The software would need to connect with the main server through the internet, so to be able to gain information of any new viruses that are brand new to be able to protect your computer system. If the anti-virus software doesn’t receive an update about any new viruses then the software

This is a security system that was executed in software or hardware that is used to prevent unauthorised access to or from an intranet which is a private network, firewalls are frequently used during that time. They work by filtering packets of data as they enter or leave the network, on the other hand they apply security to some particular applications, firewalls are like the front line for defence, they make sure that everything is secure before they allow anyone to enter or leave the network, which can help keep not only the computers but also the organisations and information safe.

Internet safety has been an extensive issue for children and adolescents since accuse to the Internet has become readily available in homes. With Internet use increasing at such rapid rates and a large proportion of adolescents using the Internet daily, the awareness of Internet safety should be addressed. The term Internet safety can be defined as “the knowledge of maximizing an individuals safety to private information, and self protection from using the Internet”. The impact and influence that the Internet has on adolescent life is far-reaching and research findings by Norris (2007) indicate that one-quarter of the American youth that go online at home, do so in the privacy of their rooms. Additionally, with the recent trend of wireless connections there has been a profound expansion in private Internet usage. The diverse means by which adolescents are using the Internet has become coupled with inherent risks of unsupervised and uneducated use.

A firewall is a system or group of systems that enforces an access control policy between two or more networks. The means by which this control is accomplished varies widely, but in principle, the firewall is a pair of mechanisms, one that blocks traffic and one that permits traffic. Some firewalls emphasize blocking traffic, while others emphasize permitting traffic. The most important thing to recognize about a firewall is that it implements an access control policy. If you don't know what kind of access you want to permit or deny, or you let someone else or some product configure a firewall based on judgment other than yours, that entity is making policy for your whole organization.

Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself.

There are various types of firewall both software and hardware. According to The National Institute of Standards and Technology (NIST) 800-10, firewalls is divided into three basic types, The Proxys firewall, Stateful Inspection firewall, and Packet Filtering firewall. The packet filtering firewall is the simplest type of firewall is a type of firewall which uses a list of firewall security rules which are able to restrict traffic based on Internet protocols, addresses and or port number. Utilizing this type of firewall management program web traffic allows for the flow of all web traffic to involve web base intrusion. In situations like this the user will need to also employ some form of intrusion prevention program along with their already established firewall security. This will help tell the difference between good and bad web traffic.
