Protocol analysis is a complicated, and often intimidating, subject. Many engineers, even ones with significant experience, feel powerless and lost when confronted with the sea of data that a network capture can provide. Most courses approach this problem with more overload; diving into each menu item and option with detailed explanations. But when you get done with those courses, you still find yourself wondering “How do I actually use this stuff to resolve problems?”This course is differentThis course is specifically designed to walk you through the mindset and methodology an expert uses to diagnose problems with Wireshark. No time is wasted on options or features that are not heavily used. Instead, the key skills are trained, with a focus on making sure you understand why this skill is useful, and how the skill is used. Real problems are examined from real network captures, and the techniques used to diagnose these problems are laid bare. Throughout this course, you will open the same captures as the instructor, and use the same techniques he uses to see the same results he gets. In this course, you will learn: How to install Wireshark to both take and view captures How to take the best possible captures, maximizing signal and reducing noise How to filter captures using both individual and combined filtering, to arrive at the exact information you need Advanced techniques like comparison captures and ring buffering to diagnose complex corner cases How to use RFCs to understand the function of the protocols you are examining How to use captures to troubleshoot both common and complex problems, such as TCP retransmissions and Black Hole routersAdditionally, you w

For most organizations today, the adoption of Cloud infrastructure is more prevalent than ever and along with that comes Cloud based Active Directory. As an organization, you want to simplify authentication procedures across all enterprise applications and that can be achieved through Single Sign-On (SSO).In this tutorial I’m going to walk through how you as a ServiceNow Administrator can configure Azure AD to control what users and groups are populated in your ServiceNow environment, and establish Single Sign-On services to the ServiceNow application as well.In the Azure portal, on the ServiceNow application integration page, select single sign-on.In the Select a single sign-on method dialog box, select SAML mode to enable single sign-on.On the Set up single sign-on with SAML page, select the pen icon to open the Basic SAML Configuration dialog box.In the Basic SAML Configuration section, perform the following steps of configuringa. For Sign on URLb. For Identifier (Entity ID)c. For Reply URLd. In Logout URLOn the Set up single sign-on with SAML page, in the SAML Signing Certificate section, You can have Azure AD automatically configure ServiceNow for SAML-based authentication. To enable this service, go to the Set up ServiceNow section, and select View step-by-step instructions to open the Configure sign-on window.Configure ServiceNowSign on to your ServiceNow application as an administrator.Activate the Integration - Multiple Provider single sign-on Installer plug-in by following these steps:a. In the left pane, search for the System Definition section from the search box, and then select Plugins.b. Search for Integration - Multiple Provider single sign-on Installer then, Install and activate it.In the left pane, search for the Multi-Provider SSO section from the search bar, and then select Properties in the Administration.<
