2013 Outlook - CompTIA

2013 Outlook - CompTIA

Network+ Finding the Best Route To Success William Saichek Professor, Computer Science and Information Systems Orange Coast College Perspectives on Teaching Network+ We all know the Network+ Certification objectives This exam will certify that the successful candidate has the knowledge and skills required to troubleshoot, configure and manage common network wireless and wired devices. Knowledge and skills include: Establishing basic network design and connectivity Understanding and maintaining network documentation Identifying network limitations and weaknesses Implementing network security, standards and protocols The successful candidate will have a basic understanding of emerging technologies including unified communications, mobile, cloud and virtualization technologies. CompTIA Network+ Objectives (N10-006) Perspectives on Teaching Network+

Looking a the objectives, we all see a wealth of opportunities to bring in practical, hands-on activities to our classes. Just look at some great possibilities Terminate cables (I know we ALL have students patch and punch CAT5e/6-RJ45 and RG6-FType cables) Networking Services DHCP/DNS/NAT/Port Forwarding IPv4 and IPv6 (especially IPv6) Subnetting VLANs and Trunking QoS Routers and Routing Protocols Can you say Other than Cisco Firewalls pfSesnse (Open Source) VPNs and RADIUS Encryption techniques (IPSec/L2TP vs SSL) Wireless Access Points

Networking Services File / Print Voice Over IP Audio/Video Streaming using Real-time protocols Video Surveillance Virtualization and Storage Packet / Network Analysis Wireshark everywhere WiFi Pineapple Power Over Ethernet & Powerline Ethernet Remote Monitoring Cloud-based VPN-Based Traditional Thick Wireless Controllers

Mesh Bridges Security Non-WiFi (802.11) Bluetooth Zigbee Z-Wave WeMo Micro-controllers Mobile device activated Voice Activated So Looking at the list of lab possibilities, how can we integrate these labs into a Network+ class, given Relevance In most cases, a Network+ class is a 100-level class where students have little or no networking background (maybe the A+ class) There is no practical networking foundation that answers the question And this is important why?????

Lack of specific vendors dilute the marketability of the technical concepts Facilities Many of the labs use combinations of expensive servers, routers, firewalls, workstations, etc In fact it could be argued that each student (or group of students) should have their own datacenter to work with Equipment Costs Commercial / Industrial networking hardware (Cisco, Palo Alto), servers (Dell, HP) and storage (EMC, Netapp) is expensive to purchase and maintain even at Academy pricing So Welcome to The Internet of Things So Welcome to The Internet of Things Lets start with the first go to source Wikipedia The Internet of Things (IoT) is the network of physical objects or "things" embedded with electronics, software, sensors and connectivity to enable it to achieve greater value and service by exchanging data with the manufacturer, operator and/or other connected devices. Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure.

In 2005 the World Summit on Information Society posited By embedding short-range mobile transceivers into a wide array of additional gadgets and everyday items, [we are] enabling new forms of communication between people and things, and between things themselves. At the Internet of Things conference held in Zurich in 2008 (yeah, there are now whole conferences on the topic) it was stated The term "Internet of Things" has come to describe a number of technologies and research disciplines that enable the Internet to reach out into the real world of physical objects. So Welcome to the Internet of Things Hmmmmm So, how could we describe The Internet of Things Could you say a Practical Accessible Relevant Current FUN Application of

Network Technologies Why Use IoT as a Practical Approach to Teaching Network+ Practically every Network+ objective is present in IoT technologies The IoT Industry is advancing at faster rate than anyone has envisioned. There are dozens of new devices being released all the time The leveraging of standard networking protocols has been accelerated The security issues STILL have not been addressed In fact the more devices that are deployed, the more vulnerable we are The human elements that IoT technologies influence are being ignored And, most importantly, the technology is FUN TO WORK WITH And, if its fun, students are much more ENGAGED More and More Players are Joining the Party Traditional IT Companies

Cisco Has just introduced a new class into the Networking Academy curriculum Packet Tracer v7 has incorporated a whole cadre of IoT devices Microsoft Apple We think Apple has evolved to something beyond a traditional IT company Newer, smaller (more nimble??) IT Companies TPLINK DLink Belkin (they even have a whole line WeMo) Nest (well, it was bought by Google we may NOT want to talk about it) There are literally hundreds of small companys making s*** using the same chipsets

What they all have in common Works with Alexia More and More Players are Joining the Party Thingy Manufactures Samsung GE Sylvania Amazon Google Honeywell Philips Siemens Technologies Allen Bradley

Leviton Lighting Lutron Lighting Carrier HVAC Ecobee HVAC Bose Audio Logitech AV Controls Schlage Locks Kwikset Locks Orvibo and many, many more Network+ and The Internet of Things The Internet of Things will attract NEW students from many diverse backgrounds Students from traditional computer science In order to program IoT applications, students MUST understand network technologies and network protocols

Students from Trade Industries Construction Architecture Plumbing and Electrical Industrial Engineering Aerospace Manufacturing Aviation (think Drones ) Using IoT in a First Year Network+ Class No Prerequisites Picks up students from other programs Introduces basic concepts Cable Construction Basic Electronic and Instrumentation Concepts

Basic Networking OSI Networking Model Infrastructure (lower layers) Wired WiFi Zwave, Zigbee, Bluetooth, etc TCP/IP Addressing and Protocols Audio / Video Distribution Basic HVAC controls Lighting Controls Security and Surveillance Using IoT in a First Year Network+ Class Take the basic concepts and expand with more in-depth hands-on labs Discussion of protocols and their implication

For example, using Wireshark to do packet and traffic analysis Team-level working with associated technology areas Architecture Construction HVAC and Environmental Systems Interior Design System-level design and integration Large scale practicum Using IoT in a First Year Network+ Class Security and Advanced Networking VPN Access OpenVPN on open-source DD-WRT routers and Raspberry Pis RADIUS Servers FreeRADIUS on Raspbery Pis

Firewalls pfSense IoT Appliances / Storage Services Steaming media services CODECs and Encryption Voice Over IP Network Attached Storage Using IoT in a First Year Network+ Class Controller Applications Home Assistant Software Simple to setup and program Raspberry Pi based Open Source

Large User Base Great Documentation Extensive Component Support https://home-assistant.io/ Use commercial and industrial microcontrollers Samsung Wink Using the IDEs design and implement custom skills Program an integrated activity that can be initialed by voice command through the Amazon Echo or the Google Home Variety of networking fundamentals are in the set up Ethernet & WiFi as well as other wireless protocols such as Zigbee and Z-Wave TCP/IP protocols (including UDP, SNMP, RTP/RTSP) VPNs, Port Forwarding and Static NAT Approaching the Internet of Things In the Classroom There are FANTASTIC opportunities to establish relationships with other departments and programs

Architecture Construction Technologies HVAC Electronics Interior Design Health Care Information Digital Media Arts Aviation Science and Unmanned Arial Systems Challenges in Teaching Network+ Using IoT Technologies You will need lots of things The pieces are small, and individually, not expensive However, you will need multiples of the things Students come in from other programs with little to no networking background

Buy-in from the programs who would be using the things Instructors will need to have knowledge of the things For example: Thermostats knowledge of HVAC Media Distribution knowledge of Audio/Video technologies Lighting Controls knowledge of electrical wiring and lighting design VoIP knowledge of the public switched telephone network Home Security knowledge of legal issues 17 Challenges in Teaching Network+ Using IoT Technologies And the number one challenge SECURITY

Both knowledge and teaching 18 Network+ Labs Using IoT Technologies Ok, so lets talk about labs The goals for all of the labs are: IoT Use of IoT technologies to teach topics relevant to Network+ Rather than buy lots of expensive servers , workstations, routers, switches and APs Use virtualization (desktop and/or server)* Use Raspberry Pis as a network appliance or a client Use inexpensive DD-WRT based AP/Routers or OpenWRT in a VM Use inexpensive managed switches or VM-based infrastructure Repurpose older technology from your Cisco Academy If you have Netlab+ or NetlabVE in your school, some of the labs are available from NDG and CSSIA Use open source as a training method

Yes, Microsoft thinks its Brain Taking Over the World, but to really teach networking, it is important to use non-MS generically enhanced protocols ** Many of the best networking and service appliances are based on Linux and are open source FreeNAS / Open Media Vault / XPEnology NAS and SAN FreeRADIUS RADIUS Server OpenVPN SSL VPN Server and Clients FreePBX Voice Over IP Gateway iSpy IP surveillance Plex Media Server Media Distribution (well, its not open source, but it is free) * If youre school is an VMware IT Academy or has a VMAP program, you have use of VMware ESXi and Workstation licenses ** That said it is still important to teach MS networking using server and desktop environments. Your school should have a Microsoft Imagine account that can provide lab licenses Network+ Labs Using IoT Technologies

Honeywell Nest Ecobee Carrier Physical Security Schlage and Kwikset Door Locks Ring Doorbells Motion and Door Open Sensors Practicum Create an Integrated Network+ / IoT Activity The heart of IoT is the interconnection between devices Referred to as Sensors Actuators There needs to be something in the middle to manage these interactions This is the Microcontroller Until recently, it was a Tower of Bable ... everything is proprietary Insteon, Control4, Crestron, etc NOW we have been transitioning to STANDARDS

TCP/IP Ethernet & WiFi Zigbee & Z-Wave One of the newest players, Samsung, has created a Microcontroller that can support almost any IoT device through the network But Samsung DID NOT want to write all of the device drivers and the activities So they created a developer platform and are encouraging the development and dissemination of devices and activities Demonstrations OpenVPN Services FreePBX / Voice Over IP Samsung SmartThings Hub Programming Integrated Control Using Alexia Echo / SmartThings Hub / Osram Lights
