EAP-TLS Authentication with an NPS RADIUS Server
EAP-TLS Authentication with an NPS RADIUS Server 802.1X/EAP-TLS (Extensible Authentication Protocol-Transport Layer Security), defined in RFC 5216, provides secure authentication methods. Client devices (RADIUS supplicants) and a RADIUS authentication server verify each other's identity by validating the signature on the computer and server certificates that they send one another. This authentication method uses an infrastructure that includes a RADIUS authentication server that communicates with an external LDAP database. It also needs a mechanism for installing certificates on the server and all the supplicants, which you can do with a Windows NPS (Network Policy Server) using a GPO (Group Policy Object) to distribute computer certificates and an 802.1X SSID client configuration for wireless access. You can also employ the same infrastructure to authenticate users (also referred to as RADIUS supplicants) who submit user names and passwords to the authentication server. This document explains how to set up the following components to provide wireless client and user authentication through 802.1X/EAP-TLS: • (Aerohive) An 802.1X SSID that instructs APs (RADIUS authenticators) to forward authentication requests to an NPS RADIUS server • (Windows) An NPS RADIUS server that accepts authentication requests from the APs and EAP-TLS authentication requests from clients • (Windows) A GPO to deploy computer certificates and a wireless network configuration to clients • (Aerohive and Windows – optional) An Aerohive and NPS configuration in which different RADIUS attributes are returned based on authentication method (EAP-TLS or PEAP-MS-CHAPv2 in this example) assigning one user profile to clients authenticating by certificate and another to users authenticating by user name/password.

Utility-Grade Core Network Services
WHITEPAPER Utility-Grade Core Network Services The infoblox appliance-based platform integrates distributes, and manages DNS, DHCP, IPAM, TFTP, NTP and more to drive networks and applications Executive Summary Networks and applications have become highly dependent on a collection of essential core network services that are not always “visible” or on the forefront of IT project lists. For example, virtually all applications, including web, e-mail, ERP, CRM, and Microsoft’s Active Directory require the Domain Name System (DNS) for their basic operation. Most IP-based devices, including laptops and desktops, require Dynamic Host Configuration Protocol (DHCP) to obtain an IP address. Newer devices such as IP phones, RFID readers, and cameras that are network-connected require file transfer services (via TFTP or HTTP) to receive configuration information and firmware updates. If core network services are compromised, networks and applications fail. These failures often manifest themselves as “network” or “application” issues but are often caused by failure of the underlying core network services themselves. A majority of enterprises still use an “ad-hoc” collection of disparate systems to deploy core network services and are, therefore, experiencing growing problems with availability, security, audit-ability, and real-time data integration that threaten current and future applications. For more than a decade, the focus of networking professionals has been on physical network architectures with high levels of redundancy and fault-tolerance. From the endpoint inward, enterprise networks are designed to provide high availability with device redundancy and multiple paths among users and data. One of the key components of these architectures has been the network appliance, purpose-built devices that are designed to perform a specific function such as routing, switching, or gateway applications.

RADIUS Tunnel Preference for Load Balancing and Fail-Over
RADIUS Tunnel Preference for Load Balancing and Fail-Over The RADIUS Tunnel Preference for Load Balancing and Fail-Over feature provides industry-standard load balancing and fail-over functionality for an Layer 2 Tunnel Protocol network server (LNS), rather than requiring the use of a Cisco proprietary Vendor Specific Attribute (VSA). The feature conforms to the tunnel attributes that are to be used in a multivendor network environment as defined in RFC 2868, thereby eliminating interoperability issues among network access servers (NASs) manufactured by different vendors. • Finding Feature Information, page 1 • Prerequisites, page 2 • Restrictions, page 2 • Information About RADIUS Tunnel Preference for Load Balancing and Fail-Over, page 2 • How RADIUS Tunnel Preference for Load Balancing and Fail-Over is Configured, page 4 • Configuration Example for RADIUS Tunnel Preference for Load Balancing and Fail-Over, page 4 • Additional References, page 4 • Feature Information for RADIUS Tunnel Preference for Load Balancing and Fail-Over, page 6 • Glossary, page 6 Finding Feature Information Your software release may not support all the features documented in this module.

Breaking PPTP Vpns Via RADIUS Encryption
Breaking PPTP VPNs via RADIUS Encryption Matthias Horst, Martin Grothe, Tibor Jager, and Jorg¨ Schwenk Horst Gortz¨ Institute, Ruhr-University Bochum matthias.horst, martin.grothe, tibor.jager, f joerg.schwenk @rub.de g Abstract. We describe an efficient cross-protocol attack, which enables an at- tacker to learn the VPN session key shared between a victim client and a VPN endpoint. The attack recovers the key which is used to encrypt and authenticate VPN traffic. It leverages a weakness of the RADIUS protocol executed between a VPN endpoint and a RADIUS server, and allows an “insider” attacker to read the VPN traffic of other users or to escalate its own privileges with significantly smaller effort than previously known attacks on MS-CHAPv2. 1 Introduction The Point-to-Point Tunneling (PPTP) protocol [5] implements a confidential and au- thenticated virtual private network (VPN) tunnel in public computer networks like the Internet. In this work, we analyze the security of PPTP using MS-CHAPv2 in combi- nation with a RADIUS authentication server. This is a standard setting, which is used in large-scale and enterprise networks, where RADIUS is used to centralize user man- agement and to perform authentication for different applications. Large scale analysis of public VPN service providers shows that over 60% of these still offer PPTP [14]. Contributions. We describe an efficient cross-protocol attack, which enables an attacker to learn the VPN session key shared between a victim client and a VPN endpoint. The attack recovers the key which is used to encrypt and authenticate VPN traffic, usually with the Microsoft Point-to-Point Encryption (MPPE) [9] scheme.

FREERADIUS TECHNICAL GUIDE CHAPTER 1 - INTRODUCTION WHAT IS FREERADIUS? Chapter 1 - Introduction
THE FREERADIUS TECHNICAL GUIDE CHAPTER 1 - INTRODUCTION WHAT IS FREERADIUS? Chapter 1 - Introduction This chapter describes: • What is RADIUS? • What is FreeRADIUS? • FreeRADIUS benefits • FreeRADIUS case studies 1.0 What is RADIUS? RADIUS, which stands for “Remote Authentication Dial In User Service”, is a network protocol - a system that defines rules and conventions for communication between network devices - for remote user authentication and accounting. Commonly used by Internet Service Providers (ISPs), cellular network providers, and corporate and educational networks, the RADIUS protocol serves three primary functions: • Authenticates users or devices before allowing them access to a network • Authorizes those users or devices for specific network services • Accounts for and tracks the usage of those services For a detailed look at how RADIUS performs these functions, see section 2.2, “The RADIUS Session Process”, on page 11. 1.0.1 History In 1991, Merit Network, a non-profit internet provider, required a creative way to manage dial-in access to various Points-Of-Presence (POPs) across its network. In response to this need, RADIUS was created by Livingston Enterprises. At the time RADIUS was created, network access systems were distributed across a wide area and were run by multiple independent organizations. Central administrators wanted to prevent problems with security and scalability, and thus did not want to distribute user names and passwords; instead, they wanted the remote access servers to contact a central server to authorize access to the requested system or service. In response to contact from the remote access server, the central server would return a “success” or “failure” message, and the remote machines would be in charge of enforcing this response for each end user.

A Framework for the Development of Mobile Social Software on Android
A Framework for the Development of Mobile Social Software on Android Robert Lübke, Daniel Schuster, and Alexander Schill Computer Networks Group, Technische Universität Dresden, Dresden, Germany {robert.luebke,daniel.schuster,alexander.schill}@tu-dresden.de Abstract. Nowadays, social aspects can be found in more and more mobile applications. Analyzing the domain of mobile social software and especially the offered features shows much similarity in the different apps. A framework that supports often used functionalities can facilitate and speed up the development of new innovative mobile applications. This paper presents the Mobilis framework, which aims to extensively support the developers of mobile social software. It provides often used features and offers the functionality in a service environment, that can easily be integrated into new mobile applications. Keywords: social software, mobile computing, framework, social network, group formation, collaboration, XMPP, Android. 1 Introduction In the last years social networks have gained a huge popularity. Nowadays they connect millions of internet users with each other. Facebook Places1, Foursquare2 and Gowalla3 are well-known examples of apps that combine social networking and pervasive computing and thereby form the trend of pervasive social com- puting. While many social platforms are accessible via apps for mobile devices, they do not unfold their full potential until the connected users can interact and collaborate with each other in a way that is adapted to the current situa- tion and technical infrastructure. With collaborative features users interact with each other in a target-oriented way to reach a common goal and they coordi- nate each other with their mobile devices.

Bintec/Teldat VPN gateway configuration Contents Bintec/Teldat VPN gateway configuration for SMS PASSCODE ................................ 1 Connect Radius .............................................................................................. 1 Bintec/Teldat VPN gateway configuration for SMS PASSCODE In this scenario about the VPN configuration on the Bintec gateway, an IPSec peer configuration entry is created which allows the simultaneous connection of multiple clients (IPSec Multi-User). Following the IPSec pre-shared key authentication, the One-Time Passcode (OTP) authentication between the Bintec VPN client and the SMS PASSCODE™ server is completed via a RADIUS server, in this case a Microsoft Network Policy Server (NPS). Note Instead of the Multi-User IPSec configuration, there is also the option to create a separate IPSec peer configuration entry for each VPN client. The priority of the Multi-User IPSec peer must always be lower than other IPSec peer configuration entries. Connect Radius To connect the RADUIS server to the Bintec VPN gateway, go to the following menu: 1. Go to System Management -> Remote Authentication -> RADIUS ->New. System Management->Remote Authentication->RADIUS->New Proceed as follows: 1. Select Authentication Type XAUTH in order to enable authentication via the Windows Server. 2. Enter theServer IP Address, e.g. 172.16.105.131 , to communicate with the Microsoft RADIUS server. 3. Enter the shared password used for communication between the RADIUS server and your device, e.g. supersecret . 4. Press OK to confirm your entries. An address pool must be created to assign an IP pool to the VPN profile of the Multi-User IPSec peer. 1. Go to VPN -> IPSec -> IP Pools -> Add VPN -> IPSec -> IP Pools -> Add Proceed as follows: 1.

Prerequisites for Configuring the Switch for Secure Shell (SSH) and Secure Copy Protocol (SCP) The following are the prerequisites for configuring the switch for secure shell (SSH): • For SSH to work, the switch needs an RSA public/private key pair. This is the same with Secure Copy Protocol (SCP), which relies on SSH for its secure transport. • Before enabling SCP, you must correctly configure SSH, authentication, and authorization on the switch. • Because SCP relies on SSH for its secure transport, the router must have an Rivest, Shamir, and Adelman (RSA) key pair. • SCP relies on SSH for security. Consolidated Platform Configuration Guide, Cisco IOS XE 3.3SE (Catalyst 3850 Switches) OL-30686-01 1 Configuring Secure Shell (SSH) Restrictions for Configuring the Switch for SSH • SCP requires that authentication, authorization, and accounting (AAA) authorization be configured so the router can determine whether the user has the correct privilege level.

Radsec a Secure, Reliable Radiator RADIUS Protocol
October 19, 2012 RadSec a secure, reliable Radiator RADIUS Protocol Copyright (C) 2012 Open System Consultants Pty. Ltd. This white paper discusses RadSec, a secure, reliable protocol for proxying RADIUS requests. 1.0 Introduction This document provides an overview and technical description of the RadSec protocol, which provides secure, reliable RADIUS transport for Radiator and other compliant products. RadSec has been formalised as an ofﬁcial IETF RFC 6614. RadSec allows RADIUS authentication and accounting data to be passed safely and reliably across insecure networks such as the internet. 2.0 Rationale and Overview The RadSec protocol is designed to provide secure, reliable transport of RADIUS requests across insecure networks such as the Internet. It was designed by Open System Consultants in response to some of the shortcomings of the conventional RADIUS pro- tocol. In 2012, it was released as an ofﬁcial IETF RFC 6614 (http://datatracker.ietf.org/ doc/rfc6614/). The RADIUS protocol (RFC 2865) has been in use for many years and has become the de-facto standard for providing AAA (Authentication Authorisation and Accounting) services. In the time since its release, it has revealed a number of serious shortcomings when used in some environments. Many operators use RADIUS proxying to send conventional RADIUS requests across insecure networks as part of various global roaming or open campus projects. Typical are educational and other institutions which permit their users to roam on the networks of their partners, and arrange to send RADIUS authentication and accounting requests to the user’s home RADIUS server, based on the user’s Realm. This is called ‘Realm- 1 of 6 Rationale and Overview based proxying’, and is usually implemented with the Radiator AuthBy RADIUS clause.
