This trend makes sense. After all, authentication is just a fancy way of saying identity verification. Proving one\u2019s identity has been a way of granting one\u2019s access to something since time immemorial. From the secret passwords used to enter Chicago\u2019s famed speakeasies to the retinal scanners used to clear you through airport security today \u2013 proving identity ensures trustworthiness and minimizes risk.&nbsp;\n<\/p>\n<p>\nToday, there are three primary methods&nbsp;that organizations rely on for network and application&nbsp;authentication:&nbsp;\n<\/p>\n<ul>\n<li><b>Password-Based Authentication&nbsp;\u2013<\/b>&nbsp;Passwords are the most common methods of authentication. Passwords can be in the form of a string of letters, numbers, or special characters. To protect yourself you need to create strong passwords that include a combination of all possible options.&nbsp;Of course, humans are lazy and tend to stick to what they know\u2026meaning the same password gets used almost universally&nbsp;\n<\/li>\n<li><b>Multi-Factor Authentication&nbsp;\u2013&nbsp;<\/b>\nMFA authentication methods and technologies increase the confidence of users by adding multiple layers of security. MFA may be a good defense against&nbsp;most account hacks, but it has its own pitfalls.&nbsp;\n<\/li>\n<li><b>Certificate-Based Authentication&nbsp;\u2013&nbsp;<\/b>\nCertificate-based authentication technologies identify users&nbsp;or&nbsp;devices by using digital certificates. A digital certificate is an electronic document based on the idea of a driver\u2019s license or a passport.&nbsp;This is perhaps the strongest means of authentication.&nbsp;\n<\/li>\n<\/ul>\n<p>Now,&nbsp;\n<i>Mission Impossible<\/i>&nbsp;fans might say&nbsp;\n<i>hey, wait a minute, biometric authentication is missing&nbsp;off&nbsp;this list.\n<\/i>&nbsp;They\u2019re not wrong, but frankly&nbsp;we\u2019re not really focused on physically breaching CIA headquarters at Langley to get our hands on the coveted NOC list&nbsp;here.&nbsp;Rather, let\u2019s focus on the day-to-day use of authentication&nbsp;techniques&nbsp;adopted&nbsp;by&nbsp;employees&nbsp;during&nbsp;business&nbsp;hours.&nbsp;\n<\/p>\n<h3>I\u2019m&nbsp;On&nbsp;the Network: Great, Now What?<\/h3>\n<p>\nThe efficacy of the network authentication methods above can be debated to no end. That\u2019s not why we\u2019re here. Once a person\u2019s device is authenticated to a corporate network, there are several security considerations that pure-play authentication tools can\u2019t address.&nbsp;\n<\/p>\n<p>\nFor example:&nbsp;\n<\/p>\n<ul>\n<li>\nIs the connected user an employee, guest, or contractor?&nbsp;\n<\/li>\n<li>\nWhat\u2019s the user\u2019s role within the organization (i.e.&nbsp;seniority or department)?&nbsp;\n<\/li>\n<li>\nWhat can the user access on the network?&nbsp;\n<\/li>\n<li>\nWhat\u2019s stopping the user from accessing resources that shouldn\u2019t be available to them?&nbsp;\n<\/li>\n<li>\nHow do you monitor the risk posture of the connected device?&nbsp;\n<\/li>\n<li>\nHow do you know if&nbsp;that user\u2019s device becomes infected with malware?&nbsp;\n<\/li>\n<li>\nCan you prevent that infected device from moving across the&nbsp;network?&nbsp;\n<\/li>\n<li>\nIs there a way to return&nbsp;a non-compliant device back to a healthy state?&nbsp;\n<\/li>\n<\/ul>\n<p>\nInside that medley of questions are a grab bag of other more detailed and technically intricate considerations that network security administrators&nbsp;may worry about. The point is this: once a user authenticates their device to the network, how can you prevent that device from posing a risk to the organization, even if unintentional?&nbsp;If you\u2019re solely relying on authentication methods for network security, the answer is: you can\u2019t.&nbsp;\n<\/p>\n<h3>Closing the Gap on&nbsp;Network Security Blind Spots<\/h3>\n<p>\nThe list of considerations above boils down to needing three primary capabilities on top of network authentication when it comes to network security. Without these, you\u2019re essentially flying blind, unable to determine the true security posture of your network. &nbsp;\n<\/p>\n<p>\nThese capabilities include:&nbsp;\n<\/p>\n<ul>\n<li>\n<b>\nAccess Control&nbsp;\u2013&nbsp;\n<\/b>\nIf&nbsp;authentication is the first step, employing access control is the second. Here, you\u2019re aiming to dictate who can access what across your network.&nbsp;For example, you may not want&nbsp;Marketing to access Accounting\u2019s VLAN. Why?&nbsp;Because Accounting\u2019s&nbsp;VLAN holds sensitive financial information that has no bearing or relevancy to the day-to-day operations of Marketing.&nbsp;\n<\/li>\n<li>\n<b>\nEndpoint&nbsp;Risk&nbsp;Posture&nbsp;Assessment \u2013&nbsp;\n<\/b>\nThe ability to continually monitor the risk threshold of each endpoint connected to your network&nbsp;means knowing how vulnerable you are to compromise. N\network administrators will typically define a risk assessment policy, which assigns a risk score to each device. This score will indicate the level of risk posed by the device, taking into consideration the status of the device\u2019s firewall, antivirus, applications in use&nbsp;and more.&nbsp;\n<\/li>\n<li>\n<b>\nProactive Device Remediation \u2013&nbsp;\n<\/b>\nIn some instances, the network security team may define a series of remediation policies. Essentially, a remediation policy consists of unattended corrective and preventive actions (CAPA), automatically applied to devices upon every transmission or on a recurring basis. A remediation policy can be used to reduce devices\u2019 risk scores and increase compliance levels for network access.&nbsp;\n<\/li>\n<\/ul>\n<h3>Unifying these Security Essentials With NAC<\/h3>\n<p>\nThere is only one type of cybersecurity technology that brings together network authentication, access control, risk monitoring and remediation. That\u2019s \n<a href=\"https:\/\/www.portnox.com\/use-cases\/network-access-control\/\">\n<span data-contrast=\"none\">network access contro\n<\/a>\nl (NAC).&nbsp;NAC, such as&nbsp;\n<a href=\"https:\/\/www.portnox.com\/portnox-clear\/\">\n<span data-contrast=\"none\">Portnox&nbsp;CLEAR NAC-as-a-Service\n<\/a>\n, unifies these network and endpoint security essentials in a single platform, and helps you fill in these critical gaps that an authentication-only approach fails to cover:&nbsp;\n<\/p>\n<ul>\n<li>Device profiling for contextual understanding&nbsp;<\/li>\n<li>Role-based&nbsp;and location-based&nbsp;access control&nbsp;<\/li>\n<li>Segmentation through dynamic VLAN assignment&nbsp;upon authorization&nbsp;<\/li>\n<li>Risk mitigation through device posture monitoring&nbsp;<\/li>\n<li>Device quarantining based on risk score&nbsp;policies&nbsp;<\/li>\n<li>Automated device remediation&nbsp;of&nbsp;non-compliant devices&nbsp;<\/li>\n<li>\u2026the list goes on\u2026&nbsp;<\/li>\n<\/ul>\n<p>Ultimately, anything less than complete network security coverage&nbsp;enforced through a NAC system&nbsp;that brings together these essential capabilities isn\u2019t&nbsp;\u201cnetwork&nbsp;security\u201d&nbsp;\u2013&nbsp;it\u2019s holding on to a hope and a prayer.&nbsp;Rely on&nbsp;standalone&nbsp;authentication tools at your own peril \u2013 we\u2019ll just have to say&nbsp;<i>we told you so<\/i>.<\/p>\n\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-2004c86 elementor-widget elementor-widget-shortcode\" data-id=\"2004c86\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"shortcode.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-shortcode\">\t\t<div data-elementor-type=\"page\" data-elementor-id=\"18103\" class=\"elementor elementor-18103\">\n\t\t\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-748947f elementor-section-full_width elementor-section-height-default elementor-section-height-default\" data-id=\"748947f\" data-element_type=\"section\" data-e-type=\"section\" data-settings=\"{&quot;jet_parallax_layout_list&quot;:[{&quot;jet_parallax_layout_image&quot;:{&quot;url&quot;:&quot;&quot;,&quot;id&quot;:&quot;&quot;,&quot;size&quot;:&quot;&quot;},&quot;_id&quot;:&quot;c4f773e&quot;,&quot;jet_parallax_layout_image_tablet&quot;:{&quot;url&quot;:&quot;&quot;,&quot;id&quot;:&quot;&quot;,&quot;size&quot;:&quot;&quot;},&quot;jet_parallax_layout_image_mobile&quot;:{&quot;url&quot;:&quot;&quot;,&quot;id&quot;:&quot;&quot;,&quot;size&quot;:&quot;&quot;},&quot;jet_parallax_layout_speed&quot;:{&quot;unit&quot;:&quot;%&quot;,&quot;size&quot;:50,&quot;sizes&quot;:[]},&quot;jet_parallax_layout_type&quot;:&quot;scroll&quot;,&quot;jet_parallax_layout_direction&quot;:&quot;1&quot;,&quot;jet_parallax_layout_fx_direction&quot;:null,&quot;jet_parallax_layout_z_index&quot;:&quot;&quot;,&quot;jet_parallax_layout_bg_x&quot;:50,&quot;jet_parallax_layout_bg_x_tablet&quot;:&quot;&quot;,&quot;jet_parallax_layout_bg_x_mobile&quot;:&quot;&quot;,&quot;jet_parallax_layout_bg_y&quot;:50,&quot;jet_parallax_layout_bg_y_tablet&quot;:&quot;&quot;,&quot;jet_parallax_layout_bg_y_mobile&quot;:&quot;&quot;,&quot;jet_parallax_layout_bg_size&quot;:&quot;auto&quot;,&quot;jet_parallax_layout_bg_size_tablet&quot;:&quot;&quot;,&quot;jet_parallax_layout_bg_size_mobile&quot;:&quot;&quot;,&quot;jet_parallax_layout_animation_prop&quot;:&quot;transform&quot;,&quot;jet_parallax_layout_on&quot;:[&quot;desktop&quot;,&quot;tablet&quot;]}]}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-7995c19\" data-id=\"7995c19\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-a437045 elementor-widget elementor-widget-image-box\" data-id=\"a437045\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image-box.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-image-box-wrapper\"><div class=\"elementor-image-box-content\"><h3 class=\"elementor-image-box-title\">About Version 2 Digital<\/h3><p class=\"elementor-image-box-description\">Version 2 Digital is one of the most dynamic IT companies in Asia.
