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)>802.11 sniffer out in corporate office parking lot

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

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)

Top 10 Remote Security Risks

Risk 6: E-mail

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

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.

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!
