Secure Network

The network can be defined as a connection between the worldwide web i.e. servers, a group of computers, and your computer. Anything you do on your computer over the internet sends data from your computer to the servers using this network. Hence your network should be secure. There are some software that monitors your network and can extract data from the network. To have a secure network, you need to install a firewall. Secure networks can be established with the help of computer protection software and by this, I mean antivirus software. There are lots of software available over the internet that claims to be computer protection software and helps you to secure your pc from viruses and malware. 

What Is Antivirus Software? How Antivirus Software Works

Antivirus can be defined as software that scans the system for the presence of virus trojan horse, spyware, etc, and delete them and thereby secure the devices from the virus. As the name suggests, it is software and implemented in software only. This pc protection software helps to save the system from internal as well as external software attacks. In simple words, if you install antivirus software in your system and your system has some viruses in it, the software starts scanning and after detecting viruses, it deletes them and hence prevents your system from getting corrupt,. This is how antivirus software fights with internal threats. Now if you insert Pendrive or any other storage device and suppose that Pendrive has a virus, antivirus software will scan prior to open the pen drive and delete the pendrive virus. This is how antivirus software protects you from external threats. Some software also scans files that you download from the internet and will delete if found suspicious. This was the working of Antivirus software in computer.

What is firewall | Firewall definition

A firewall is a network security software that monitors incoming data and allows it to pass only if found safe. Data is transferred in the form of data packers,  firewall applies packet filter and acts as a barrier between the internet and your network. Inbound and outbound traffic is being monitored by the firewall and filters any data packets for suspicious files or content. It is implemented on both software as well as hardware and hence, it also protects the system, from the data coming from hardware. The main function of a firewall is to monitor network traffic and prevent any unauthorized entry into the system. Unlike antivirus software, it cannot protect from internal threats.
