![]() ![]() ![]() The organization had recently implemented Cisco Systems Identity Services Engine (ISE) and had hired a pen-testing firm to evaluate its efficacy in preventing unwanted access to the network. A network penetration tester easily bypassed their access controls by cloning a mac address from an IP phone to a Linux laptop computer, Background To explore the issues, we are going to evaluate the case of an organization that had recently implemented a network access control solution. However, with a defense in depth approach using basic tools and techniques, the risk and impact can be largely mitigated. The problem with this approach is MAC address spoofing is trivial to implement. Media Access Control (MAC) Addresses commonly are used to identify endpoints for purposes of access control and authorization on access layer networks that have yet to implement 802.1x (dot1x) device authentication. ![]() 4.3.2 Creating the policy that references the vendor class.3.2.3 Anomalous Endpoint Detection (AED).3.2 Effect of MAC address spoofing on the profiler.3.1.4 Policy Set Authorization (AuthZ) rule. ![]() 3.1.1 Endpoint Database and Endpoint Attributes. ![]()
