How Boards use the NIST Cybersecurity Framework as a Roadmap to oversee cybersecurity

Transcription

1 How Boards use the NIST Cybersecurity Framework as a Roadmap to oversee cybersecurity Why is the NIST framework important? GOH Seow Hiong Executive Director, Global Policy & Government Affairs, Asia Pacific Cisco Systems December 2017

2 As board members Does your company s management report to the Board on cybersecurity? Regularly? Do you know when was the latest breach in the company? Do you know the damage from the last breach? Do you know the extent of the breach?

3 THE EVOLVING THREAT LANDSCAPE What threats do I face?

4 Evolving business needs Dynamic threat landscape Complexity and fragmentation Security Challenges Shortage of cyber security experts Changing regulations and business models Widening IT/Board communication gap Attack surface Threat actors Attack sophistication Fragmented security Not interoperable Not open Talent crunch Niche security skills Increased costs

5 THE BIGGEST PROBLEM Do I know if I ve been compromised?

6 Cyber Attack No If but When Source: Verizon 2012 Data Breach Investigation Report

7 Whack-a-mole Approach

8 Recognizing Malware is Difficult and Not Enough

9 How easy is it to breach?

10 MY IT GUYS ARE ON IT! How are they managing security?

11 Management Nightmare

12 Complexity is a Significant Obstacle to Security Business Constraints Complexity 35% Budget (-4%) 28% Compatibility Issues (-4%) 1-5 (45%) 6-10 (29%) (18%) (7%) Over 50 (3%) Vendor 55% of organizations use 6 to >50 security vendors 2016 (n=2,850) 25% Lack of Trained Personnel (+3%) 25% Certification Requirements (+/-0%) 1-5 (35%) 6-10 (29%) Products 65% of organizations use 6 to >50 security products (Change from 2015) (21%) (11%) Over 50 (6%) 2016 (n=2,860)

13 Device enrollment challenges await. 374 new devices per second 10 min to connect and define policy 7.8 person-days of effort per second 245.8M person-days of effort per year

14 How do deal with the challenges? Holistic not piecemeal approach

15 Evolution of defensive tactics Medieval defense Modern defense

17 Effective security requires integrated threat defense Integrated threat defense Firewall and security infrastructure Leverage the network Advanced threat intelligence Governance processes Before During After

18 NIST Cybersecurity Framework Voluntary, open, transparent drafting process Voluntary, consensus-based standards leveraged Voluntary use of Framework by private sector Input to regulation & government procurement

19 NIST Cybersecurity Framework Recovery planning; Improvements; Communications Recover Identify Asset management; Business environment; Governance; Risk assessment; Risk Management strategy Protect Access control; Awareness training; Data security; Information protection processes & procedures; Protective technology Response planning; Communications; Analysis; Mitigation; Improvements Respond Detect Anomalies and events; Security continuous monitoring; Detection processes

20 How do I measure? Metrics

21 Metrics Mean time to detect Mean time to contain Mean time to recovery Does your management measure these?

22 Detection is key Current average time-to-detect: days Cisco in 2015: time-to-detect at 2 days Today: Cisco Time-to-detect at 6 hours Cisco in independent tests (NSS) 70% of breaches detected < 1 min 90% of breaches in 3 minutes 99% detection within 6 hours 100% in 24 hours

23 Looking forward

24 Collaborating with Partners Governments International bodies Private sectors and customers
