Information traveling through a network is in the form of packets. The firewall inspects each packet for any hazardous threats. If it finds them, it will immediately block them.<\/p>\n<h3><b>Protection against malware<\/b><\/h3>\n<p>Malware, especially the type of Trojan, is dangerous to a user. A <a href=\"https:\/\/en.wikipedia.org\/wiki\/Trojan_horse_(computing)\" target=\"_blank\" rel=\"noopener\">Trojan<\/a> silently sits on your computer, spying on all the work you do. Whatever information they gather will be sent to a web server. You will not know their presence until you notice the strange behaviors on your computer. A firewall in this instance will immediately block Trojans before they cause any damage to your <span style=\"box-sizing: border-box; margin: 0px; padding: 0px;\">s<strong>ystem<\/strong><\/span><b>. Hackers.<\/b><\/p>\n<p>Hackers on the internet always search for computers to carry out their illegal activities. When they find such computers, they start to do malicious activities, such as spreading viruses. Apart from those hackers, unknown people, such as neighbors, can also look out for an open internet connection. Therefore, to prevent such intrusions, it is a good idea to have firewall security.<\/p>\n<h3><b> Control Access<\/b><\/h3>\n<p>Firewalls come with an access policy that can be implemented for specific hosts and services. Attackers can exploit some hosts by blocking them from accessing the system. This access policy can be enforced if users feel they need protection from unwanted access.<\/p>\n<h3><b>Privacy<\/b><\/h3>\n<p>Privacy is one of the major concerns of a user. Hackers constantly look for private information to get clues about the user. However, by using a firewall, many of the services a site offers, such as the Domain Name Service (DNS), can be protected. Hence, hackers have no chance of getting private details. Additionally, firewalls can block the site system&#8217;s DNS information. Due to this,\u00a0 the names and IP addresses will not be visible to the hackers.<\/p>\n<h3><strong><span class=\"has-inline-color has-vivid-cyan-blue-color\">Easy Installation <\/span><span class=\"has-inline-color has-vivid-cyan-blue-color\"><br \/>\n<\/span><\/strong><\/h3>\n<p>The installation process of a software firewall is quite simple, and you can do it without any professional guidance. Moreover, there are some useful tutorials on the internet that help you learn the complete process in detail. Modern Operating systems like <em><span class=\"has-inline-color has-vivid-cyan-blue-color\">Windows 7, Windows 8, and Windows 10 <\/span><\/em>come with pre-installed firewalls. However, the hardware firewall is challenging to install and maintain. To access them, we need to take professional advice.<\/p>\n<h2><b>Disadvantages of a Firewall<\/b><\/h2>\n<ul>\n<li><b>User limitation<\/b><\/li>\n<li><strong>Cost<\/strong><\/li>\n<li><b>Performance <\/b><\/li>\n<li><b>Malware Attacks<\/b><\/li>\n<li><strong><span id=\"Complexity\">Complexity<\/span><\/strong><\/li>\n<\/ul>\n<h3><b>User limitation<\/b><\/h3>\n<p>There is no doubt that firewalls prevent unauthorized access to your system from the network. While this can be advantageous for an average user, it can be a problem for large organizations. The firewall&#8217;s policies are strict enough to prevent employees from performing certain operations. As a result of this, the overall productivity of the company can be severely affected. Sometimes this can also prompt employees from using backdoor exploits. However, this can lead to security problems since the data that travels through the travel door exploit is not examined properly.<\/p>\n<h3><b> Cost <\/b><\/h3>\n<p>Firewalls do require an investment, depending on the type. In general, hardware firewalls are more expensive than software firewalls. Besides, hardware firewalls require installation and maintenance, which can be costly. These types of configurations do not work without an expert IT employee. Compared to a software firewall, there is little investment, and it is easy for an average user to deploy.<\/p>\n<h3><b>Performance <\/b><\/h3>\n<p>Firewalls, especially software-based ones, have the capability to limit your computer&#8217;s overall performance. The processing power and the RAM resources are the factors that affect overall performance. When the software firewalls constantly run in the background, they consume more processing power and RAM resources, leading to diminished system performance. However, hardware firewalls do not impact the system performance since they do not rely upon computer resources.<\/p>\n<h3><b>Malware Attacks <\/b><\/h3>\n<p>Even though firewalls can block the basic types of Trojans, they are defenseless against other types of malware. These types of malware can enter your system in the form of trusted data. Therefore, even if you have a firewall, it is still recommended that you have anti-malware software installed on your PC. The only way to remove them is through an anti-malware scan.<\/p>\n<h3><strong><span id=\"Complexity\">Complexity<\/span><\/strong><\/h3>\n<p>Even though firewall maintenance is easy for small businesses, it is definitely not for large organizations. Large organizations require a separate staff to operate them. These people ensure it is safe enough to protect the network from intruders.<\/p>\n<h3><strong>Conclusion<\/strong><\/h3>\n<p>So, we explained the Advantages and Disadvantages of Firewalls.
