Range vs Rate Typical Indoor Application Benefit comparison: 802. 11 a • Fewer sources of interference • Easily scalable • Maximum cell overlap 802. 11 g • Greater range • Backwards compatibility with 802. 11 b 28

802. 11 a/b/g Coverage Example 29

Trends • 802. 11 g is by far the leading WLAN technology in enterprise (new install), followed by 802. 11 b (largest installed base) – Both are 2. 4 GHz. • 802. 11 a is still around, but growth is slow. • 802. 11 n in development for 100 Mb/s speeds – 300 Mb/s and 600 Mb/s also in the queue 30

Wireless A-B-C A-Pick a PHY Layer B- Pick a Topology C- Choose Security

Wireless- Choose a Topology • Basic Service Set (BSS) - A group of stations communicating with each other • Independent Basic Service Set (IBSS) - BSS communicating in Ad-Hoc Mode • Infrastructure Basic Service Set (Infrastructure BSS) - BSS communicating in Infrastructure (AP) Mode • Extended Service Set (ESS) - BSS’s connected together through a backbone network 32

Wireless- Choose a Topology • BSSID (Basic Service Set Identifier) - Usually the MAC address of the AP hosting the BSS clients - Used by all BSS Stations in the Frame Header • SSID (Service Set Identifier) - Name given to all AP’s in an ESS - Transmitted in non-encrypted management frames 33

Wireless- Choose a Topology • Beacons - Announce the existence of a network and it’s parameters - Define the basic service area for a BSS • Probe Requests - Used by stations to scan an area for existing 802. 11 networks - Include the SSID and rates supported by the station • Probe Responses - Sent in response to Probe Requests by the AP or assigned Ad-Hoc Station - Contain all information found in the Beacon Frame 34

Wireless- Choose a Topology • 802. 11 Authentication (Two-Step) - The process of a station identifying itself before being allowed to transmit frames • Association (Two-Step) - The process of a station “registering” with a chosen AP AFTER 802. 11 authentication. The AP registers the station on the network. Association is the equivalent of “plugging in” to a wired network. 35

802. 11 State Transitions (The Minimum) State 1 Unauthenticated and unassociated Can send only Control, Probe, Beacon and Authentication frames State 2 Authenticated and unassociated Can now send Association frames State 3 Authenticated and associated Can now send all frames, including Data 41

Identify Your Coverage Locations • Keep the antenna away from metal obstructions such as heating and air-conditioning ducts, large ceiling trusses, building superstructures, and major power cabling runs. If necessary, use a rigid conduit to lower the antenna away from these obstructions. • The density of the materials used in a building's construction determines the number of walls the signal must pass through and still maintain adequate coverage. Consider the following before choosing the location to install your antenna: – Paper and vinyl walls have very little affect on signal penetration. – Solid and pre-cast concrete walls limit signal penetration to one or two walls without – – – • degrading coverage. Concrete and wood block walls limit signal penetration to three or four walls. A signal can penetrate five or six walls constructed of drywall or wood. A thick metal wall causes signals to reflect off, causing poor penetration. A chain link fence or wire mesh spaced between 1 and 1 1/2 in. (2. 5 and 3. 8 cm) acts as a harmonic reflector that blocks a 2. 4 Ghz radio signal. Install the antenna away from microwave ovens and 2 -GHz cordless phones. These products can cause signal interference because they operate in the same frequency range as the device to which your antenna is connected. Install the antenna horizontally to maximize signal propagation. 42

Choose Your Antenna • • This choice will be limited to application – Indoor vs outdoor – Point to Point vs multipoint Omnidirectional Directional – Yagi – Panel – Sectoral – Parabolic Grid Remember that the Higher the Gain (dbi), doesn’t increase the range 43

Wireless A-B-C A-Pick a PHY Layer B- Pick a Topology C- Choose Security

WLAN Security Q&A Key Questions: – How can I protect against war drivers? – Are there rogue devices in my network? – How does wireless relate to my other security solutions? Challenges: – The rogue user (war drivers) Challenge (Geek, thief, or both? ) – The User Policy Challenge – The Authentication + Encryption Challenge Result: – Secured wireless network 45

Let me introduce you to “The War Driver” 46

“The War Driver” Tools of the trade! 47

“The War Driver” Their goal “to map out the wireless world for all to use!” 48

The User Policy Challenge: How do I ensure users aren’t bringing in rogue equipment from home? Fact 1: You have wireless, whether you know it or not. . . • • • Home APs cost <$50 and are widely available Home equipment may not respond to SNMP queries All home equipment is a security hole out of the box Design Approaches: • • Outlaw private wireless LAN equipment Enforce the policy with periodic walkthroughs 49

The Authentication + Challenges: My authentication methods are top-notch so I’m safe, right? My WLAN data is encrypted so I’m safe, right? 50

WLAN Security = Authentication + Encryption Early Security “Solutions” • Don’t Send Beacons? • Don’t Broadcast my SSID? • Filter MAC addresses? • How about a VPN? 51

WLAN Security = Authentication + Encryption “Trivial” Authentication Methods Include • OPEN • WEP (Wired Equivalent Privacy) • WPA-PSK (Wi-Fi Protected Access/Pre-shared Key) – Also called 802. 11 i-PSK These methods can be easily Hacked!! 52

802. 1 X AUTHENTICATION • The premise of 802. 1 X is to authenticate the User NOT the machine • Also Called WPA or WPA “Enterprise” • Based on the Extensible Authentication Framework Protocol (EAP) • uses a RADIUS server to provide authorization, authentication and accounting (AAA) services • does not specify authentication mechanism 53

802. 1 X- Different EAP Methods • LEAP (Lightweight EAP) • TLS (Transport Layer Security) • TTLS (Tunneled TLS) & PEAP (Protected EAP) – Establish a TLS tunnel w/certificates – Encrypt a legacy or unencrypted authentication Protocol – Examples of “inner” authentication protocols include: Eap-MD 5 Challenge, EAP-Generic Token Card, EAPMSCHAP-V 2 – Non-Eap incl. PAP, CHAP, MS-CHAP LDAP, Kerberos 54

Example- Transport Layer Security (TLS) AP Authenticate Request w/ Client Certificate Server Certificate Client/AP Session Key Good • Strong Encryption • Session-based • WEP compatible • MS and Cisco supported Bad • Client-based certificates Overall Recommended for new installs 55

Example- Tunneled TLS (TTLS) Authentication Request Server Certificate Client/AP MD 5 Hash, Username/Password Client/AP Session Key Good • Strong Encryption • Session-based • WEP compatible • no client-side certificates Bad • Not standardized Overall Recommended for shops with existing client auth. systems 56

Authentication Types Etherscope provides: • Static WEP • • WPA PSK (Pre-Shared key) 802. 11 i PSK (Pre-Shared Key) • WPA – EAP TLS, LEAP, PEAP GTC, PEAP MD 5, PEAP MS-CHAP, PEAP TLS • 802. 1 X – EAP TLS, LEAP, PEAP GTC, PEAP MD 5, PEAP MS-CHAP, PEAP TLS • WPA 2/802. 11 i – EAP TLS, LEAP, PEAP GTC, PEAP MD 5, PEAP MS-CHAP, PEAP TLS 57

WLAN Security = Authentication + Encryption Methods: • WEP (Wired Equivalent Privacy) • Dynamic WEP (w/802. 1 X) • TKIP (802. 11 i - Temporal Key Integrity Protocol) • CCMP (802. 11 i - Counter Mode with CBC-MAC Protocol) - CCMP also known as WPA-2 58

WEP Overview Request Challenge Static Key Request Granted 59

The WEP Challenge: Can I count on WEP as my security solution? Fact 2: WEP has 3 Critical Flaws • 40 AND 128 bit keys can be easily hacked • re-keying clients is a management nightmare • susceptible to “man-in-the-middle” attacks Design Approaches: • Several Short-term solutions • A couple of emerging long-term solutions 60

61

WPA • WPA (Wi-Fi Protected Access) -Improves WEP by adding key management and addressing flaws in original WEP - Uses 802. 1 X for Authentication - Uses TKIP for Encryption 62

Encryption Key Management • TKIP (Temporal Key Integrity Protocol) – Manages/changes WEP keys -Multiple Master Keys -Per-Frame Keying -Sequence Counter -New Message Integrity Check (MIC) -Launch of Counter-measures! (Re-check validation, shut-down communications, Key refresh) 63

WPA 2 • WPA 2 improves on WEP by addressing the last “flaw” – Based on 802. 11 i standard – RC 4 encryption mechanism is replaced by AES (Advanced Encryption Standard) which is much more robust. • Requires appropriate chipset in Access Point • FIPS 140 -2 eligible (Government approved – strong encryption) 64

WPA (why it’s better!) 65

SO, What can I do? • “War drivers” will access your network if you leave an open door. – Most will look for easier targets if you have ANY security – WEP is enough to discourage only casual users • Remember, WEP is completely ineffective against real hackers!! – Use WPA at the very least, and if possible WPA 2, with 802. 1 x authentication 66
