Lecture 1 introduction

  1. 1. Network Design &AdministrationITEC20231Dr Jon Robinson (CIB 308)
  2. 2. Summary of Module• Second year module – 20 credits• Pre-requisite: ITEC10241 Introduction to Networks Network Design & Administration• Part of Computer Systems Programmes • Security and Forensics • Networks • Engineering 2
  3. 3. Aim of Module• “To enable you to plan, configure and manage networking solutions to support business needs” Network Design & Administration• Must understand business aspects and technical facilities available to achieve the business goals – within the constraints of cost and practically. 3
  4. 4. Learning Outcomes• You should be able to: • Analyse a straightforward need and suggest / evaluate possible solutions. • Fulfil the legal obligations of a network Network Design & Administration administrator. • Setup and manage a server. • Configure appropriate security technology. • Use network / server administration software. 4 • Interpret technical information.
  5. 5. Teaching Methods• Lectures (whole year: 24/25 )• Seminars (approx. 5/6) – requiring groups to study cases and provide solutions.• 2 hour lab sessions (approx. 10) – carry out Network Design & Administration exercises setting up and testing small networks (virtual ones!)• Additional labs in term 3 on client/server technology (using thin clients and dedicated HP server), forensic technology and (hopefully!) network intrusion / defence. 5
  6. 6. Resources• VLE – Lectures, seminar sheets & lab sheets• MSDN & TechNet• Books: Network Design & Administration • “The practice of Systems and Network Administration”, 2nd Edition, T. Limoncelli (ISBN: 0-321-49266-8) • “Unix and Linux System Administration Handbook”, 4th Edition, E. Nemeth, (ISBN: 978- 0-13-148005-6) 6
  7. 7. Assessment Methods• Exam (50%) – testing knowledge of network admin principles and skills at design and evaluation. Network Design & Administration• Coursework (50%) – assessing your practical and evaluative abilities, partly from a log book (20%) but mostly from a lab phase test (80%).• Success requires attendance and 7 interaction at all elements of the module!
  8. 8. Contents• Similar to parts of Microsoft MCP exams and some Linux content.• You need to go into much more detail if Network Design & Administration you wish to take MCP exams – knowing detailed specifics of tools and their limitations.• Module will use Windows 7, Windows Server 2008 R2 and Linux to allow 8 exercises to be carried out.
  9. 9. Course Contents• Network Admin – legal requirements and relevant ISO standards• Monitoring and administering network elements• Powershell scripting and cmdlets Network Design & Administration• Different server roles• Domains• Users, computers and groups• ACL’s and other aspects of control/monitoring• Backup/recovery• Security and reliability (a bit on encryption!)• Organisation, process and documentation 9• Cloud Computing & Virtualisation
  10. 10. Networks – a reminder• What is it? “A group of interconnected computers” (Wikipedia)• Why? Network Design & Administration • In business terms, what do computers do? [1] • Enhance inter-human communication • Speed up routine tasks • Improve human decision making• Networks enhance this even further 10
  11. 11. Essentials of a Network• These days we tend to the Client / Server model with the following elements: • Client – a PC with a GUI to run programs Network Design & Administration • Server – a more powerful PC providing services e.g. databases and other applications • Physical Network – LAN or WAN • Logical Connection – “glue” to connect 11 client to service
  12. 12. Client/Server Computing Other networks Router or Gateway Network Design & Administration Server Clients 12
  13. 13. Assumed NetworkInfrastructure• Physical components – cabling, routers, gateways, hubs, switched, even free space (wireless).• Already covered in ITEC10241 and further Network Design & Administration covered during Communications Technology module.• We will assume that the technology required is present and (mostly) working. Labs and discussions will concentrate on access control 13 and data structure.
  14. 14. The One Inviolable Rule “It is always a compromise”• Any network you build / configure / maintain will be a compromise… Network Design & Administration Features  Cost Convenience  Security Reliability Speed / Cost 14
  15. 15. Next Time…• Servers & Services Network Design & Administration 15
