1 La mobilité en milieu académique et la sécurisation des applications sans fil

2 Agenda Réseaux académiques : état des lieux Défis des Hautes Ecoles Maturité des réseaux mobiles Pourquoi Aruba? Intégration des solutions de sécurité Valeurs ajoutées de Juniper Exemple d un Campus numérique «on line»

3 Institution publique Les réseaux aujourd hui en milieu académique Espace public Intérieur & Extérieur Administrative University Hospital Library, Classrooms Cafeteria Student Housing Stadium Faculty Housing Satellite Campus Haute densité Connexions concurrentes public averti Extensions du réseau limitées Accès Guest, Points d accès publics Couverture de réseau difficile Points d accès FAT gestion difficile sécurité limitée Besoins : - Rester compétitif car les accès aux TIC sont un MUST pour les étudiants - ROI et maintenance réduits - Systèmes de formations en ligne

4 Les défis des Hautes Ecoles Personnel IT qualifié réduit Budgets IT en baisse Méthodologies de gestion de projets ITIL Public averti, habitué aux nouvelles TIC Appareils portables = facilité Explosion des PC incontrôlables Sécurité de l information = Souci n 1 Accès au réseau sur tout le campus Applications e-learning Accès sécurisé pour les utilisateurs incontrôlables Déploiement de systèmes d informations pour les étudiants Convergence du réseau IP : data + voice + video Source: Gartner Group

5 Maturité des réseaux mobiles 1 ère Génération 2 ème Génération State of the Art Points d accès autonomes et distribués Pas de gestion des fréquences des émissions radio Niveau de sécurité faible Points d accès légers et centralisés Gestion active des fréquences radio Déploiements denses avec haute performance Haut niveau de sécurité et support de clients multiples Géolocalisation des clients WiFi Réseau basé sur l identité et sécurité «end-to-end» avec une encryption centralisée Mobilité à travers les réseaux LAN, WAN et Internet Facilité de déploiement des clients avec outils de géolocalisation Réseaux d envergure à travers une meilleure gestion des VLANs Haute qualité de service en fonction des clients: PC, tablet, GSM, PDA, etc. Meilleure performance basée sur les standards de gestion des fréquences radio

6 Pourquoi les solutions d Aruba? 1) Complex become simple 2) Règles de sécurité sans frontières res 3) Start small and go big

7 1 La complexité devient une simplicité Portail captif Couverture extérieure Gestion Radio Adaptative Sécurité i Shaping du trafic Serveur AAA Mobilité Tactique Stratégique Dominante Mobilité Remote AP Convergence des Applications Polices de sécurité Connexions VPN point-à-point Détection IDP Wireless

8 2 Règles de sécurité sans frontières La sécurité suit l utilisateur partout Pas de reconfiguration 1 seul SSID pour tout le réseau Configuration AAA 1 et 1 seule fois Sciences appliquées Bibliothèque Arts

9 3 Commencez petit et devenez GRAND Complexité des applications Convergence Mobilité globale Hotspots Nbre d utilisateurs concurrents Software + Hardware + Management = 1 seule plate-forme

10 Une vue de la Mobilité dans l Education selon Aruba Des possibilités illimitées d extension protègent vos investissements à très long terme Affiliated schools Libraries Remote AP-70 Student Housing Distance Learning AP-60 AP-61 ARUBA 2400 LAN AP-70 WAN Internet Partners & consultants ARUBA 6000 Satellite Campus AP-80 ARUBA 800 AP-2E Labs Remote AP-70 Teacher Access

11 PHL un campus numérique «on line» Réseau Gigabit GRID de Belnet 4000 étudiants 500 collaborateurs 160 points d accès Firewall Anti-virus, spam In & Out Authentification forte (802.1X) Financement de 1500 portables (800 euros) E-learning Blackboard Academic Suite Plus de 1200 connexions concurrentes

13 AAA Servers Identity Stores Resources WL AP Wireless Agent Wired Agent Copyright 2007 Juniper Networks, Inc. Proprietary and Confidential 13

14 Issues No server access control Access to the network = access to everything Application authentication is the only security barrier Server vulnerabilities exposed Servers, services and applications vulnerable to DoS Any unmanaged device can connect to the network and comprise server security Unmanaged devices might compromise your trusted devices Proliferation of malware, spyware, backdoors Copyright 2007 Juniper Networks, Inc. Proprietary and Confidential 14

15 Network Segmentation Juniper FW/VPN Introducing network segmentation Add firewall device to protect resources Create segments on switches (VLAN) Static firewall security policy to allow access to resources Advanced security Deep Inspection (full IDP on ISG firewall) Anti-virus, Anti-Spyware, Anti-Spam, URL filtering Traffic shaping and prioritization with QoS, DSCP Firewall user authentication allow more granular access control first step to dynamic policies Copyright 2007 Juniper Networks, Inc. Proprietary and Confidential 15

16 AAA AAA Servers Identity Stores Firewall User access to protected resources WL AP Copyright 2007 Juniper Networks, Inc. Proprietary and Confidential 16

17 Issues Static firewall access policy Access policy not related to user profiles Lots of exceptions Hard to manage Only servers are protected Clients are completely exposed Copyright 2007 Juniper Networks, Inc. Proprietary and Confidential 17

18 Introducing UAC User authentication against central Infranet Controller appliance (integration with Windows logon) Dynamic access control policies on firewall(s) Policy rules linked to user profile User disconnected policies removed End-point assessment to ensure client device security Integrates with existing user directories Re-use of group membership to create access control policies (much the same way as managing file access on windows file shares) Firewall policies can include AV, DI and URL filtering profiles Unmanaged and unauthenticated devices get restricted access to protected resources Copyright 2007 Juniper Networks, Inc. Proprietary and Confidential 18

19 AAA AAA Servers Identity Stores Central Policy Manager Dynamic Role Provisioning with SBR Dynamic Role Provisioning Endpoint profiling, user auth, endpoint policy Firewall Enforcers User access to protected resources WL AP Wireless Agent Wired Agent Copyright 2007 Juniper Networks, Inc. Proprietary and Confidential 19

20 Issues Every client is still on the same network Security enforced only at the resources When host assessment fails or unauthorized user device has no access to protected resources, but can still access the local network Not hack-proof: Can compromise other client devices Not infection-proof: Can infect other client devices Confidentiality: monitor traffic between authenticated devices and protected server resources Copyright 2007 Juniper Networks, Inc. Proprietary and Confidential 20

21 Introducing 802.1x Dynamically assign VLAN based on user authentication Unsuccessful authentication and/or host assessment results in a default GUEST VLAN Requires 802.1x supplicant and Radius server Both are included in the UAC solution and are part of the Infranet Controller appliance Automatic, central distribution of supplicant from IC Open Standards based Integrate with any 802.1x standards based switch or access point Copyright 2007 Juniper Networks, Inc.
