    1. The Technical Services Stuff in IT Services A brief tour of the technical and service offering plethora – who knew???? Technology Training Services October 2009

    2. Course Goals • To help you integrate into IT Services by gaining the technical and service-oriented knowledge needed to be more productive. • To improve your awareness of and promote the services, resources, and tools that the various groups within IT Services provide (to the campus at-large and also within IT Services). • To provide a functional overview of the services and products, and how they interrelate across computing organizations and why they are important to the campus as well as IT Services.

    3. Course Agenda The technical overview of the services provided by each of the main divisions within IT Services • Strategic Planning • Human Resources • Architecture • Research Computing • Computing Services • Communication Services • Client Support • Business Services

    4. Administrative Guide Policies • Policies: http://adminguide.stanford.edu/ • Admin Guide 1: University Code of Conduct • Admin Guide 61: Administrative Computing Systems • Admin Guide 62: Computer and Network Usage Policy • Admin Guide 63: Information Security • Admin Guide 64: Identification and Authentication Systems • Admin Guide 66: Chat Rooms and Other Forums Using Stanford Domains or Computer Services • Admin Guide 67: Information Security Incident Response • Admin Guide 81.1: Telecommunication Services • Admin Guide 81.3: Provision of Mobile Equipment and Related Services • Admin Guide 84: Credit Card Acceptance and Processing

    5. HIPAA and FERPA HIPAA (Health Information Privacy and Security) http://hipaa.stanford.edu/ Protects the privacy of an individual’s health information and govern the way certain health care providers and benefits plans collect, maintain, use and disclose protected health information (“PHI”). Be sure appropriate procedures are maintained to ensure that the HIPAA privacy and security rules are followed. FERPA (Family Educational Rights and Privacy Act) http://ferpa.stanford.edu Provides students the right to consent to disclosures of personally identifiable information contained in the student’s education records. Students, faculty, and others with questions regarding student records should contact the Office of the University Registrar. page 5

    6. Security Issues • Important security concepts all IT Services employees need to know and understand: • Admin Guide 63 • Data Classification (Confidential, Restricted, Prohibited) http://www.stanford.edu/group/security/securecomputing/dataclass_chart.html • Encryption • Passwords: always use a secure connection when sending your password! • Kerberos • Secure Socket Layers (SSL) and Secure SHell (SSH) • Stanford Desktop Tools • Computers: be aware of how to encrypt the contents of your computer! • Stanford Whole Disk Encryption: (SWDE) http://www.stanford.edu/services/encryption/wholedisk/index.html • Windows: http://securecomputing.stanford.edu/pc_file_encryption.html • Mac: FileVault (System Preferences > Security > FileVault)

    9. Computing Services Authentication: SUNet IDs • Stanford University Network IDentifier • 3-8 character identifier • Permanent – cradle to grave – but aliases allowed! • Not private and not anonymous • Your “golden key” to online services • Password – change every 180 days • http://sunetid.stanford.edu

    10. Computing Services Authentication: Workgroup Manager • Workgroup Manager • Web application • Defines groups of community members for use on restricted web pages or applications • Workgroups are: • Lists of members in a group • Identified by their SUNet IDs • Given a name that uniquely identifies them. • Replicated into the Active Directory (AD) – more on AD later! A workgroup may also contain subgroups!

    11. Computing Services Authentication: Types of Workgroups • 3 types of workgroups: • System-maintained workgroups: stanford:student (students) stanford:academic (faculty and students) stanford:faculty (faculty) stanford:administrative (staff and faculty) stanford:staff (staff) stanford:stanford (students, faculty, and staff) • Department workgroups (often identified by the department’s assigned stem) organization:businessaffairs_its gsb:affiliates helpdesk:consultants • Individual workgroups (identified by the owner’s SUNet ID preceded by a tilde ~) ~jdoe:book_exchange ~instr:friends ~santa:naughty_children • Using workgroups (with Webauth, for example) in a .htaccess file: AuthType WebAuth AuthType WebAuth AuthType WebAuth require privgroup stanford:staff require privgroup its:directors require privgroup ~instr:friends

    12. Computing Services Authentication: Kerberos • Kerberos: • A network authentication system for use on physically insecure networks. • The heart of Stanford’s campus-wide network security infrastructure. • Prevents eavesdropping or replay attacks. • Provides for data stream integrity (detection of modification) • Prevents unauthorized reading of data using cryptography systems such as the Data Encryption Standard. • Is the official method for authentication at Stanford(see Admin Guide 64)

    13. Computing Services Authentication: Kerberos–A Screencast on How It Works From Password to Service Request to Service Ticket Screencast Played Here

    14. Computing Services Authentication: Establishing Kerberos Credentials • Windows: • Network Identity Manager (NIM) • Stanford Desktop Tools • http://www.stanford.edu/services/ess/pc/docs/kerberos/ • Macs: • Kerberos for Macintosh (runs in the background) • Stanford Desktop Tools • http://www.stanford.edu/services/ess/mac/docs/kerberos/ • Unix: • kinit • http://unixdocs.stanford.edu/loggingin.html • How does it work? • User runs NIM (Windows) or Stanford Desktop Tools (Windows/Mac) or kinit • User logs in with valid SUNet ID and corresponding password • Kerberos credentials are established!

    15. Computing Services Authentication: Web Authentication (WebAuth) • Open-source web-based system for authenticating users (developed here!) • Protects web sites on the main Stanford web servers • Can be used with other Apache-based web servers • How does it work? • User visits a protected website • Login screen appears and user enters SUNet ID and password • User’s identity and Kerberos ticket carried in a cookie • https://weblogin.stanford.edu/help.html • http://webauth.stanford.edu

    16. Computing Services Authentication: Web Login (WebAuth continued) • 2 keys are given to you when you log in: • a key to the specific web site or service you visited, • and a "master" key that opens other protected web sites. • The keys last until you quit your browser program, or until they expire – up to 10 hours later. • Be sure you have "turned in your keys" by quitting your browser before you leave your computer. • Otherwise other people can access websites as though they are you! • Note: • Using a protocol called SPNEGO, supported browsers can access protected web sites using Kerberos credentials obtained from your computer login instead of using the WebLogin screen. • For details, go to https://weblogin.stanford.edu/config.html

    17. Computing Services Authentication: Shibboleth http://www.stanford.edu/services/shibboleth/ • Lets you access secured non-Stanford sites (only those who have joined a common federation) using your SUNet ID. • Lets Stanford web servers authenticate users from those non-Stanford institutions using their local authentication credentials. • Example: COManage – Internet2 Project • Still in development… • COManage is the Collaborative Organization Management Platform developed by the Internet2 Middleware Initiative. It is intended as a demonstration of the capabilities offered by tying together federated identity management (Shibboleth), groups management (Grouper), and (coming soon) privilege management into a cohesive support infrastructure for a variety of collaborative applications. • http://middleware.internet2.edu/co/ • http://comanage-dev.stanford.edu/

    18. Computing Services Authentication: Guest Accounts • Based on email address • Uses Shibboleth as authentication • A Stanford Guest Account allows you to view specific Stanford web pages that normally require Stanford-Affiliated SUNet identification. A Guest Account might allow you to view and interact with web-authenticated department, individual, and group pages. The owner of the restricted pages can allow you to access them via your Guest Account. • Note: A Guest Account cannot be used to access any restricted data including HIPAA, FERPA, or PCI-regulated data. • http://www.stanford.edu/service/guest/ page 18

    19. Computing Services Distributed File Systems – AFS (Andrew File System) • Stanford’s campus-wide file system • Allows users to efficiently share files across local and wide area networks • System is backed up nightly • University’s main web site and linked files hosted on AFS • http://www.stanford.edu/services/afs/
