Planet PDA Spring 2003 Abstract This presentation will cover: >Proper and workable approaches for dealing with wireless security >Techniques for securing a wireless device >Available and effective security technologies >The #1 vulnerability with wireless devices (and #2, #3,...)

Planet PDA Spring 2003 “Holy Smokes … where’s my PDA?!” It has happened to everyone. If your PDA is lost or stolen: >personal information is exposed >your latest data entries are lost >and if tied into your corporate enterprise... your entire network security is compromised!

Planet PDA Spring 2003 The Need for Wireless Security

Planet PDA Spring 2003 Security Risks Physical >Loss or theft  hacker accesses data files, keys Visual >Nosy neighbors on planes, trains & automobiles Electronic >Packet sniffers on Internet >Weak or no encryption >Weak or no authentication (simple passwords) > sniffer out in corporate office parking lot

Planet PDA Spring 2003 What’s an IT Manager to Do? >Recognize the problems >Get regular notifications of threats >Study the technologies, alternatives, vendors >Stay current with OS service packs & app updates >Allocate appropriate budget >Purchase appropriate software & licenses >Limit corporate PDA purchases to specific list >Develop procedures & policies for remote usage >Train the corporate population >Develop written policies for remote access >Consider a managed service

Planet PDA Spring 2003 Specifics, Please! >Enforce use of solid passwords >Utilize built-in security mechanisms >Provide immutable forced policies >Use standard & well-maintained antivirus programs >Use file encryption for internal data, folders, etc. >Provide “device access control” – smart card, token >Enforce use of encrypted connections, VPN tunnels! >Provide and maintain a good firewall

Planet PDA Spring 2003 Electronic Security Mechanisms Protocol >IPSec is the best, WEP, SSL Keys >768-bit, 1024-bit most common >RSA signatures most common, ECC >Preshared secrets today, public keys tomorrow Encrypting Algorithms >TDES most common, AES coming Authentication >2-Factor (RSA SecurID), Certificates, PINs >Biometrics

Planet PDA Spring 2003 Getting Security Policy to All Corporate Users

Planet PDA Spring 2003 Wireless Phones, PDAs, Laptops are All Network Devices

Planet PDA Spring 2003 Intelligence Agency Technical ExpertHacker Top 10 Remote Security Risks Risk 1: PDA “local data” storage is exposed (contacts and messages) Risk 2: Clear transmission of application data Risk 3: PDA user data access via desk stand Risk 4: PDA “applications” access via desk stand (Trojan Horse) Risk 5: PDA Device to PDA Device communications are not encrypted (RIM)

Planet PDA Spring 2003 Intelligence Agency Technical ExpertHacker Top 10 Remote Security Risks Risk 6: Risk 7: No Authentication for device or network access Risk 8: Device Encryption Keys Risk 9: User applications are not secured (insertion of Trojan Horse) Risk 10: Human factors

Planet PDA Spring 2003 Secure ALL communications between the remote user and the corporate LAN Three Points of Wireless Vulnerability

Planet PDA Spring 2003 Examples of Wireless Security Products What can IT managers do to strengthen the corporate (remote) network? Software >Security in Software Hardware >Security in Silicon Accessories >Security in Add-on Devices

Planet PDA Spring 2003 VPN Client Use in PDAs, phones and laptops >Use a VPN software client that offers secure client- to-gateway communication over wireless networks >Use a product that is interoperable, with many different gateways

Planet PDA Spring 2003 VPN: Simple, Cost-Effective Use the Internet to establish secure links via >Authentication >Encryption >Secure tunneling to access business partners, branch offices, and telecommuters

Planet PDA Spring 2003 Hardware Security

Planet PDA Spring 2003 Security Embedded in Silicon Embedded security includes all relevant cryptographic functionality in hardware form as well as a full-featured software library that runs on the processors on chip. Full functionality includes: >Encryption Engines: DES/3DES, ARC4, AES >Hash Engines: SHA-1, MD5, RIPEMD-128/160 >IPSec Packet Engine >Public Key Accelerator >RSA, DSA Digital Signatures >Entropy-based True Random Number Generator (RNG) 2.5G and 3G device manufacturers, wireless service providers, and wireless application providers, in using embedded silicon, provide accessibility to all cryptographic functionality in any combination of hardware and software.

Planet PDA Spring 2003 Smart Card Readers Secure Tokens Device Access Control allows only YOU to power up the device and/or use the select applications CARD ACCESS CONTROL

Planet PDA Spring 2003 Protecting the Platform DEVICE SECURITY  PIN & Biometric access control  File-based encryption  Unchangeable VPN policies  Application-level controls  Time-of-day access granularity

Planet PDA Spring 2003 Summary >Assess your risk >Protect the data on the remote phone, PDA, laptop >Protect the network with a VPN >Establish and enforce security policies and procedures >Stay current with all new security threats If you take basic precautions and use the techniques outlined here you CAN be safe in a wireless world!
