3
Motivation (1/5)

• Need for wireless security as popularity of WLANs
  rises.
• Instead of focusing solely on max coverage, this
  project looks into physical security.

4
Project Overview (2/5)

• Developing a Deployment Tool devoted to finding
  best places for access points while
• Providing maximum coverage
• Minimizing leakage outside building

5
Project Overview (2/5)

• The Deployment Tool will
• Simulate signals being transmitted and received
  as in a WLANRay Tracing

6
Project Overview (2/5)

• The Deployment Tool will
• Provide a colored map indicating where signals
  are strong/weakCoverage Map

7
Project Overview (2/5)

• The Deployment Tool will
• Indicate where access point(s) should be placed
  in buildingAccess Point Map

Access Points
8
Project Overview (2/5)

• Equipment to be used
• Donated Equipment from Army Research Laboratory
  (ARL)
• 3 Access Points
• 6 Wireless Laptop Cards (802.11x)
• 2 Laptops for Measurements
• A 2.4G Hz Spectrum Analyzer

9
Background (3/5)

• Security Risks to WLANs that this project will
  address
• Signal Interception due to signal leakage, which
  can lead to
• Insertion attacks (Unauthorized devices)
• Monitoring of wireless traffic (Sniffers)
• Misconfiguration (SSID, WEP)
• Jamming (Denial of service)

10
Background (3/5)

• Ray Tracing Program
• Revolves around a Floor Plan File
• 2 Sections to a Floor Plan File
• 3D Data containing locations of walls, ceilings,
  etc.
• Electromagnetic properties of walls, ceilings,
  etc.

11
Background (3/5)

• Ray Tracing Program
• Has two sections
• Geometric (for Signal Paths)
• Uses 3D Data in Floor Plan File

12
Background (3/5)

• Ray Tracing
• Has two sections
• Electromagnetic (for Signal Strengths)
• Uses Electromagnetic Data in Floor Plan File

13
Project Plan (4/5)
14
Project Benefits (5/5)

• Collaboration with Army Research Laboratory (ARL)
• Could lead to user-friendly software
  commercialization
