It checks whether the device complies with predetermined security policies before granting or denying access. The process typically involves endpoint security checks, identity verification, and compliance assessments. If a device meets the specified criteria, it is granted access; otherwise, it may be placed in a restricted or quarantined network segment.<\/span><\/p>\n<h2 style=\"text-align: justify;\"><span class=\"ez-toc-section\" id=\"Capabilities_of_Network_Admission_Control\"><\/span><span style=\"font-family: Cambria; font-size: 22px;\"><strong>Capabilities of Network Admission Control:<\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ol style=\"text-align: justify;\">\n<li>\n<p style=\"text-align: justify;\"><span style=\"font-family: Cambria; font-size: 15px;\"><strong>Endpoint Security Checks:<\/strong>\u00a0NAC examines the security posture of devices seeking access, verifying the presence of up-to-date antivirus software, firewalls, and other essential security components.<\/span><\/p>\n<\/li>\n<li>\n<p style=\"text-align: justify;\"><span style=\"font-family: Cambria; font-size: 15px;\"><strong>Identity Verification:\u00a0<\/strong>Users and devices must authenticate themselves before gaining network access.
