2 Incident Response: Categories of Cybercrime Activity April to June % 27% 12% 9% 7% 7% 5% 2 Ransomware Banking Trojan Business Compromise * DoS, unknown, digital currency mining and credential harvesting Web Script Adware Spam Other *

3 The Evolution of Ransomware Cybercrime has matured into a business sector The latest paradigm is Cybercrime-as-a- Service (CaaS) The Ransomware market, within this paradigm, is rapidly maturing Ransomware strains are being upgraded, rebranded, and sold cheaply on the Dark Web All potential targets, regardless of size, present equal opportunities 3

4 True Costs of Ransomware Ransom: $30,000 Lost Revenue 2,500,000 Incident Response 75,000 Legal Advice 70,000 Lost Productivity 250,000 Forensics 75,000 Recovery & Re-Imaging 60,000 Data Validation 25,000 Brand Damage 500,000 Litigation 200,000 Total Costs of Attack $3,785,000 4

6 Traditional Strategies Are Not Enough Data Encryption Tape Backups Cyber Insurance Not preventative against attacks Hacktivists can encrypt your encrypted data For data protection, not recovery Potential negative impacts on cost to store, replicate and protect Too long to recover Difficult to validate data Requires backup infrastructure to recover May not protect: Backup Catalog PBBA [Data Domain] Tape Library Meta Data DB All breaches may not be covered Policies have baseline security requirements Monetary limits may not cover all damages Does not protect: Patient needs Brand Lost trust 6

7 Current State: Risk Profile Summary Technical All data is currently susceptible to a cyber attack Primary storage replication can replicate corruption Backup catalog not replicated Recovery of backup catalog from tape is slow and failure prone Backup copies not isolated from network People & Process IT Engineering and Ops have access to most if not all Backup Assets Security teams not assigned to assets. Bad actors inside the firewall can create havoc. Franchise critical and non-critical data are not segregated Backup images can be expired without authorization These risks are consistent with traditional Prod/DR models. This is a different challenge and requires a different architecture. 7

8 Current State: What is a Business Impact Analysis? A process to understand: What is the monetary impact of a disaster of failure? What are the most time-critical and information-critical business processes? How does the business REALLY rely upon IT Service and Application availability? What availability and recoverability capabilities are justifiable based on these requirements, potential impact and costs? Composed to two components Technical Discovery Data Gathering Human Conversation Talk to People! 8

9 BIA Output: The Most Critical Data First Compute Protect the heartbeat of the business first Applications Validate & Store Highest Priority Data Prioritize top applications or data sets to protect Usually less than 10% of data Start with a core set and build from there 9

10 Layered Cyber-Security for Data Protection Level of Protection Good Better Best Traditional Data Protection Best Practices Deploy a layered data protection approach ( the continuum ) for more business critical systems but always include a point in time off array independent backup with DR Replication (N+1) Protect Born in the Cloud and endpoint Data Additional Hardening and Protection Features Product specific hardening guides Encryption in flight and/or at rest Retention lock with separate security officer credentials Advanced Protection Services Isolated recovery solution EMC/EY service offerings: assess, plan, implement, and validate Use of evolving security analytics: RSA & Secureworks 10

15 Proactive Analytics in the IR Vault Why Analytics in the Vault? Increase effectiveness of Prevent/Detect cybersecurity when performed in protected environment. Diagnosis of attack vectors can take place within an isolated workbench. App restart activities can detect attacks that only occur when application is initially brought up.
