Poorly configured networks are vulnerable to many attacks. Easy attacks. In this blog we will demonstrate how easy it is to perform a DoS attack on a DHCP scope. Afterwards, we will remediate our poorly configured network devices with a security feature that you should include on every deployment to protect against this type of attack.

Anyone operating a PKI or an application whose functionality requires one, can attest to the ever-increasing amount of time spent keeping certificates up-to-date and compliant with the contemporary cryptography standards. When certificates expire, things break. When cryptography standards evolve, things break. For these reasons, the typical network/systems operator may find it...

Endpoint Captive Portal Detection - Why?

This blog assumes that you have a general understanding of ISE Central Web Authentication. Endpoint Captive Portal Detection plays a critical role in improving the end-user experience when connecting to a captive portal protected WiFi network, such as an ISE CWA protected WiFi network. The captive portal detection brings to the attention of the user that...

In the first entry of this series, we looked at the high-level mechanics involved in using AnyConnect with the ISE Posture module to perform endpoint host inspection (posture) when connecting to an AnyConnect VPN head-end (ASA/FTD). In the second entry of this series, we narrowly focused on getting the ISE posture module provisioned. In the third entry, we took stock of all the available posture...

In the last entry of this series, we looked at the high-level mechanics involved in using AnyConnect with the ISE Posture module to perform endpoint host inspection (posture) when connecting to an AnyConnect VPN head-end (ASA/FTD). If you haven’t read that one yet, you can find it here!

In this entry, we will be narrowly focused on provisioning the ISE posture module. Enjoy!

Project Manager: “We need to give them access to our network.”

IT Security: “No.”

Project Manager: “We really need to give them access to our network.”

IT Security: “Still no.”

Project Manager: “C’mon, pleeease??”

IT Security: “Ok fine. But we’ll need to assess their computer for vulnerabilities.”

Welcome back! In this blog we’re going to continue where we left off in the last entry where we looked at using Microsoft Intune to provision the native wired 802.1x supplicant on Windows 10. This time, we shift our focus to the wireless 802.1x supplicant. If you missed that one, be sure to check it out! OK! Let’s go!

Welcome back! In this blog we’re going to take a detour from our TrustSec series to introduce some modern endpoint management techniques in Microsoft Intune. Almost every customer we are working with is starting the journey to modern endpoint management with Microsoft Intune. As the functionality of Azure AD + Intune continues to mature, that once far away thought of shutting down those Microsoft...
