1 Strategies and Best Practices to Implement a Successful Data Loss Prevention Program Sebastian Brenner, CISSP Principal Systems Engineer Symantec LAMC

2 Agenda 1 What DLP is and its purpose 2 Challenges for a sustainable data protection program 3 Common attributes in a successful implementation 4 Achieve greater risk reduction

3 What is Data Loss Prevention (DLP)? Definition: Data loss prevention (DLP) is a strategy for making sure that end users do not send sensitive or critical information outside the corporate network. The term is also used to describe software products that help a network administrator control what data end users can transfer. (1) Where is your confidential data? How is it being used? How best to prevent its loss? (1) loss prevention DLP

4 Protect what s Important Customer Information Company Information Credit Card Info Intellectual Property Medical Records M&A and Strategy SSNs and Government IDs Internal Auditing Financials HR Records

5 Some Data Loss Prevention Use Cases Better Visibility Discover Data Theft Risk Reduction Legal and Regulatory Compliance

6 Features to Consider in a Data Loss Prevention Solution Office 365 ios Android USB Hard Drives Removable Storage Network Shares Print/Fax Cloud & Web Apps Unified Management Web FTP IM File Servers Exchange, Lotus SharePoint Databases Web Servers

7 Features to Consider in a Data Loss Prevention Solution Route Incidents to Right Responder High Severity of Incidents First Quick Detection & Response Visibility and Metrics Automation Integration High Accuracy & Low False Positives Multiple Detection Technologies Extensive Formats Localization Unified Management Flexibility Membership Granular Management Limit Data and Incident Access Exceptions Detect/Alert/Block Built in policies templates Alerts based on Risk and Severity

8 Who are the Main Players in the DLP Arena?

9 Recognize challenges for a sustainable data protection program

10 Implementing the DLP Product Suite Typical Customer Challenges Implementing the entire DLP suite without a plan ( I bought it all, I want to install it all; right now ) Not involving all affected areas of IT ( We are IT /Security and we don t need to engage others for our projects ) Not anticipating changing IT environment Database upgrades Migrations system upgrades Underestimating infrastructure needs and set up timeframes (unrealistic goals)

11 Developing the DLP Program Typical Customer Challenges Unclear or unfocused DLP program goals IT centered implementation with no Business Unit involvement Let s just see what happens approach Lack of knowledge about the information to protect (customer needs to define what is sensitive in their environment) No effort toward developing procedures for the long term

12 Operating a DLP Program Typical Customer Challenges Lack of resources Lack of data analysis No cooperation from business units Adhoc changes to policies and response rules Inability to show risk reduction progress (ROI)

13 Common attributes in a successful DLP implementation 13

14 Want success? Think differently. Traditional Approach Technology focused Incident and event centric Broad coverage approach Successful Approach People, Process, & Technology Comprehensive Prioritized and focused Typical Results Unpredictable Typical Results Predictable Technology Incomplete Scalable Inefficient Costly Technology Efficient Cost Effective People Process

15 Characteristics of Successful DLP Programs Architect / Design Executive Level Involvement Install Employee Education Technology Dedicated Experienced Resources Metrics Connection Trained Incident Response Team People Process Implement Prioritized Approach Optimize Operate Business Owner Involvement

16 How a comprehensive, clearly defined, business focused DLP program achieve greater risk reduction

17 Three Step Implementation Approach Plan for Success Target Most Sensitive Data First Begin Risk Reduction Begin Risk Reduction 17

18 Step 1: Plan for Success Assign a dedicated team to own project success Determine requirements, order and configure hardware Set expectations with proactive communication to employees Schedule training for System Administrator and Incident Response Team Select 1 2 key metrics for risk reporting Obtain executive buy in on initial roll out strategy

19 Step 2: Target Most Sensitive Data First Recommended Starting Points: Strategically add policies Network: High volume, high risk protocols and exit points Strategically add protocols and exit points Greatest Potential for Loss Strategically add repositories Storage: High access, highvolume repositories Endpoint: 19 Strategically add users and endpoints Users with access to highly sensitive data At risk employees

20 Step 3: Begin Risk Reduction 1000 Baseline Enable Lookups Remediation Refine Policies Notification Prevention/Protection Enable Advanced Detection Employee and Business Unit Communication Refine Policies Identify Broken Business Processes Fix Broken Business Processes Incidents Per Week Risk Reduction Over Time Business Unit Risk Scorecard Sender Auto Notification Business Unit Risk Scorecard Refine Policies Months 0 1 to 3 4 to 6 7 to 9 10 to 12 20

22 Keys to Success People & Process Engage business units and data owners to define data protection priorities Define and gain consensus on project goals and success metrics Determine awareness and communication program for DLP Focus initial deployment on 3 5 key policies Endpoint: target users with access to highly sensitive data and at risk employees (high turnover) Network: target high volume and high risk protocols (SMTP, HTTP, FTP) Storage: target high access, high volume repositories Train team prior to implementation Configure policies and define incident response workflow based on team capacity Regularly report results to key stakeholders and executives

23 Keys to Success DLP Technology Optimize system performance Filters, server management, scheduling scans and reports Precisely tune policies early Detection Technologies, Exceptions Automate to minimize resources Workflow, remediation, notification, prevention, protection, encryption Integrate with security infrastructure LDAP, encryption, messaging systems, forensics, SEMs
