It is responsible for screening the information that enters or exits a network and tracking that information. Firewalls serve as the front-line defense for any network security system, keeping out unauthorized entities seeking to access the system&#8217;s data.<\/p><p>A fine-tuned, updated, and responsive firewall is one of the most important components of a network security system. Network security experts can test the strength of a firewall by determining how easy it is to penetrate. <a href=\"https:\/\/www.eccouncil.org\/train-certify\/certified-network-security-course\/\">EC-Council&#8217;s Certified Network Defender(CND) course<\/a> provides training on a variety of secure networking practices, including firewall installation and administration.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-447dd67 elementor-widget elementor-widget-text-editor\" data-id=\"447dd67\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h3>Access Control<\/h3>\n<p>Access control refers to the systems and protocols an organization has in place to make sure that only authorized users can enter the network and access the data and information stored there. The most common tool for access control is identity and access management (IAM), which is standard in all network security protection systems.<\/p>\n\n\n<p>IAM is a comprehensive strategy that covers all of an organization&#8217;s data\u2014both in the cloud and in house\u2014and implements keys and locks for every person authorized to access it. EC-Council&#8217;s CodeRed offers a <a href=\"https:\/\/codered.eccouncil.org\/course\/identity-and-access-management?utm_source=ecc-website&amp;utm_medium=product-category&amp;utm_campaign=identity-and-access-management\" target=\"_blank\" rel=\"noopener\">complete IAM<\/a> course that teaches you everything you need to know to design, organize, and launch an access control system that ensures only authorized individuals can access a network.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-43a9e72 elementor-widget elementor-widget-text-editor\" data-id=\"43a9e72\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h3>Network Segmentation<\/h3>\n<p>You&#8217;ve probably seen a movie where the hacker cracks the code, turns to the camera, and says, &#8220;We&#8217;re in!&#8221; In real life, it&#8217;s not quite that simple, thanks in part to network security protection methods like network segmentation.<\/p>\n\n<p>Network segmentation collates an organization&#8217;s data into separate groups that share common functions, ensuring that access to one group does not guarantee outright access to another. That hacker in the movie may have breached the network on one level but does not have free rein over the entire network. Network segmentation also allows organizations to control which members of the organization have access to certain information that shouldn&#8217;t be available in the general network landscape.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3ac940b elementor-widget elementor-widget-text-editor\" data-id=\"3ac940b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h3>Intrusion Prevention Systems<\/h3><p>Intrusion prevention systems (IPSs) are designed to spring into action as soon as a network security risk is detected and respond by blocking it. The responses are generally designed by network professionals and are unique to the system they&#8217;re meant to protect, as they are built to protect that specific system&#8217;s vulnerabilities.<\/p><p>EC-Council&#8217;s <a href=\"https:\/\/www.eccouncil.org\/train-certify\/certified-network-security-course\/\" target=\"_blank\" rel=\"noopener\">CND course<\/a> trains you to create IPSs that can identify and respond to attacks and threats before they damage networks or compromise information. The lab-intensive C|ND program gives you all the hands-on training you need to implement an effective and quick-acting IPS.<\/p><h3>Employee Training<\/h3><p>One of the most effective network security protection measures that organizations can take is to ensure that everyone who has access to the organization&#8217;s network is trained not to inadvertently jeopardize the network&#8217;s security. This can happen in many ways\u2014for example, giving out information to phishers and not implementing proper security features in work-related emails or documents stored in the cloud. Organization-wide security awareness training and policies are essential components of protecting an enterprise&#8217;s network against cyberattacks.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a7f0681 elementor-widget elementor-widget-heading\" data-id=\"a7f0681\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Advance Your Network Security Education with EC-Council<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-08ead79 elementor-widget elementor-widget-text-editor\" data-id=\"08ead79\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>If you&#8217;re ready to take the next step in your network security career, enroll in EC-Council&#8217;s <a href=\"https:\/\/www.eccouncil.org\/train-certify\/certified-network-security-course\/\" target=\"_blank\" rel=\"noopener\">CND course<\/a>.
