Agenda

• Trends • Strategy • Mechanisms • ArcGIS Server • Mobile • Cloud

Trends

Trends Perception

• End-User Perception - I don’t ever hear about Virus issues in our company anymore

• Reality - Modern attacks are not as much about being visible - Layers of exploits deployed - Goal is to obtain your company’s most value information

Trends Events over the last months

• US loses $250 billion annually in IP theft • $338 billion annually in financial theft

• Result of cyber espionage is the "greatest transfer

of wealth in history."

Trends Mobile Security

• iPhone Twitter PII compromised

• Mobile device data not secure by default

Enterprise Mobile Security Solutions can help

Trends End of Browser Plug-ins?

• Migration away from Flash and Silverlight Plug-ins

• Security experts ready to unload plug-ins

• HTML5 limitation inconsistencies across browsers slowing migration

Trends Reverse Proxy’s Need to Be Maintained

• Apache Reverse Proxy Exploit – Oct 2011 • Allows unauthenticated access to information that should be confidential • Commonly overlooked component for updates

CVE-2011-3368

Update Your Reverse Proxy!

Strategy

Strategy

• Identify your Security Needs and Risks - Assess your environment - Datasets, Systems - Sensitivity, Categorization

• Understand Security Options - Enterprise-wide Security Mechanisms - Application Specific Options - Utilize patterns

• Implement Security as a Business Enabler - Improve appropriate availability of information

Strategy Security Implementation Patterns

• Risk based

• 3 categories / NIST alignment

• Selection process - Formal – NIST 800-60 - Informal

To prioritize information security and privacy initiatives, organizations must assess their business needs and risks

Strategy Security Implementation Patterns

- Basic - No Sensitive data - Public/Non-Privacy related information - All architecture tiers can be deployed on one server

- Standard - Moderate consequences with data loss or integrity - Architecture tiers are deployed to separate systems - Potential need for Federated Services

- Advanced - Sensitive data - All components redundant for high availability - 3rd party enterprise security components utilized

Strategy Security Principles - CIA

• Confidentiality - Preventing intentional or unintentional unauthorized

disclosure

• Integrity - Prevent unauthorized data modifications

• Availability - Ensures reliable and timely access to data

Strategy Security Principles – Defense in Depth

Mechanisms

Mechanisms

Authentication ArcGIS Server 10.1

• ArcGIS Server authentication - Built-in users and roles (token authentication) - LDAP or Windows Domain - LDAP or Windows Domain and the built-in store

• Web server authentication - Any identity store for which the web server has built support

Authorization Role Based Access Control

• Esri COTS - Assign access with ArcGIS Manager - Geodatabase roles

• RDBMS – Row Level or Feature Class Level - Versioning with Row Level degrades RDBM performance - Alternative - SDE Views

• Custom - Limit GUI - Rich Clients via ArcObjects - Web Applications

- Sample code Links in ERC - Microsoft’s AzMan tool

Authorization Assign access with ArcGIS Manager

Filters ArcGIS Server

• Firewalls • Reverse proxy • Anti-Virus Software

Filters ArcGIS Server - Integrating an existing proxy

• To select your port, install the Web Adaptor on another web server

Mechanisms Encryption – 3rd Party Options

• Network - IPSec (VPN, Internal Systems) - SSL (Internal and External System) - Cloud Encryption Gateways

- Only encrypted datasets sent to cloud

• File Based - Disk encryption – BitLocker - GeoSpatially enabled PDF’s combined with Certificates

• RDBMS - Transparent Data Encryption - Low Cost Portable Solution - SQL Express 2008 w/TDE

Encryption ArcGIS Server 10.1 SSL

Mechanisms Logging/Auditing

• Esri COTS - Geodatabase history

- May be utilized for tracking changes - ArcGIS Workflow Manager

- Track Feature based activities - ArcGIS Server 10+ Logging

- “User” tag tracks user requests

• 3rd Party - Web Server, RDBMS, OS, Firewall - Consolidate with a Security Information and Event Management

Issue Solution Question Physical Loss Device Security Options? Malicious App What app stores allowed? Rooted Device Encryption/Strength? Patches How enforced? Insecurely Written App How is code tested? Compromised Password How secured/encrypted? Unprotected Transport TLS/SSL Utilized? Weak Session Management Tokens always passed? Unprotected Services Hardening Guidance? Internal Resource Access VPN Options?

Mobile Enterprise Mobile Security

• Built-in device capabilities - Can store features iOS5 encrypted with Flex 3.0 API

• Enterprise device solutions (InTune, AirWatch, Good, MaaS360) - Benefits: Secure email, browser, remote wipe, app distribution

• Application specific solutions - Benefits: Secure connections and offline device data - Esri iOS SDK + Security SDK

Cloud Responsibility across cloud service models

• IaaS - ArcGIS Server for Amazon

• SaaS - ArcGIS Online

Compliance

• FDCC - Desktop products 9.3-10

• USGCB - Desktop products 10.1 – Almost completed

• SSAE 16 Type 1 – Previously SAS 70 - Esri data center operations - Expanding to Managed Services for 2012

• FISMA - ArcGIS Online – In progress

Cloud IaaS – Common security issues

• Access to ports not limited - If you utilize the default image and open RDP to all IP

addresses, expect to be compromised in as little as a day

• System patches not applied - There have been a number of significant RDP

vulnerabilities

• Authentication weak - Multi-factor authentication recommended - Check out AWS Multi-Factor Authentication (AWS MFA)

• System not hardened - Turn off/uninstall components you don’t use - Utilize built-in capabilities such as Network Level

Authentication (NLA) for RDP

Cloud SaaS - ArcGIS online for Organizations

• Organization administrator options - Require SSL encryption - Allow anonymous access to org site

• Consume Token secured ArcGIS Server services - 10 SP1 and later - User name and password prompts upon adding the service

to a map, and viewing

• Transparency - Status.ArcGIS.com

• Upcoming - Federated Identities (SAML/ADFS)

Summary

• Security is NOT about just a technology - Understand your organizations GIS risk level - Utilize Defense-In-Depth
