1 Cyber Resiliency Felicity March May

2 Cyber Resiliency Cyber Resiliency is the ability of an organization to continue to function with the least amount of disruption in the face of cyber attacks. Cyber resiliency is broader in scope comprising of both cyber security and business continuity. Cyber security is designed to protect systems, networks and data from cyber crimes. Effective cyber security reduces the risk of a cyber attack and protects organisations from the deliberate exploitation of its assets. Business continuity provides the plans and systems to resume operations when a cyber attack leads to a cyber outage causing service disruption. Thus, Cyber resiliency is an end to end initiative that brings together and addresses three critical areas... information security, business continuity and network resilience of enterprises to ensure organizations continue to function against cyber attacks and cyber outages. 2

3 IBM Cyber Resiliency High-profile cyberattacks continue to dominate the business and technology news space at alarming frequency Newsworthy cyberattacks of Aug 2016: Shadow Brokers Sep 2016-Feb 2017: Cloudbleed Oct 2016: Dyn DDOS attack Mar 2017: WikiLeaks CIA Vault 7 May 2017: Macron campaign hack May 2017: WannaCry June 2017: Petya, NotPetya, Nyetya, Goldeneye June 2017: 198 million US voter records exposed July 2017: Verizon Sep 2017: Deloitte Sep 2017: Equifax breach of 143 million records Jan 2018: Spectre and Meltdown vulnerabilities Our focus here are new, highly destructive cyberattacks 3

4 IBM Cyber Resiliency Some destructive cyberattacks will get through Ciaran Martin said the UK had been fortunate to avoid a so-called category one (C1) attack, broadly defined as an attack that might cripple infrastructure such as energy supplies and the financial services sector. The US, France and other parts of Europe have already faced such attacks. Martin said he anticipated such an attack in the next two years. He admitted total protection was impossible. Some attacks will get through. Figures for cyber-attacks since the NCSC opened through to December last year underline the pressure building on the UK from hackers. The NCSC recorded 34 C2 attacks, with WannaCry the most disruptive of these, and 762 slightly less serious C3 ones. 4

5 IBM Cyber Resiliency NotPetya got through and it could have been much worse; it was not designed to spread externally 80% of infections were in Ukraine, followed by 9% in Germany Some large firms trading in Ukraine were collateral damage Biggest thing in IBM last summer (we supported just a few affected firms) Initial infection through a legitimate software update; extremely hard to prevent, if at all possible No successful prevention of initial infection where the malware payload was downloaded Where uncontained, the infection spread everywhere in minutes Typically, within the hour affected firms lost everything, everywhere, all at once; a shock and awe moment Organisations had not designed DR solutions to withstand or to recover from a cyber-attack, resulting in recovery taking weeks or months 5

6 As a result of these new attacks board leaders have ranked cyberattacks in the top 5 of Global Risks at the World Economic Forum in Davos, Switzerland, in 2018 Global Risks that have a macro- impact across sectors. Boards across the globe need to consider how key business parameters will be influenced by these risks in view of mitigations implemented. In terms of preparedness, Cyberattacks presents a significant opportunity to de-risk the business. However a coherent strategy and understanding of underlying issues is lacking, as the impact is not fully understood at the Board Level.

14 IBM Resiliency Approach for Rapid Recovery Against Cyber Outages Recovery automation, air-gapped protection and Immutable storage are essential to rapidly recover from cyber outages. Air-gapped Protection An air-gapped solution ensures backup data is not accessible through the same network as production data Immutable storage (WORM) Verifiable Data Immutable storage systems protect your data from changes by always writing a new version Validation ensures the data or configuration that is backed up matches production data and an audit trail proves veracity Orchestration / Automation Components to meet Regulations Application aware Recovery Orchestration / automation ensures systems can be recovered rapidly in parallel Regulatory bodies impose data storage locations, timelines, audit records, format, and media rules; For e.g. Sheltered Harbor needs customer data to be stored in a third party site 14 March 2018 / 2018 IBM Corporation

15 Cyber Resiliency solutions powered by IBM Resiliency Orchestration software for Cyber Incident Recovery Cyber Incident Recovery for Platform Configuration This solution provides recovery against cyber attacks that corrupt the configuration and alter the behavior of data center platforms including network devices, storage devices, virtual devices and servers. The solution replicates the configuration data of these devices and servers into IBM immutable storage located in IBM public cloud or IBM Resiliency Data Center, and alerts the user when there is a suspicious change in configuration data and rapidly restores the original configuration to the impacted devices(s) or servers based on policies. Cyber Incident Recovery for Applications/Data This solution provides recovery against cyber attacks that corrupt the data itself. The solution replicates the data from servers and storage using copy data management products, with an air-gap mechanism, into IBM immutable storage located in the DR site of the customer and maintains multiple read-only PIT copies. When there is a cyber outage, it presents options to user to select the right copies to be restored and rapidly restores them on to DR compute infrastructure and DR storage infrastructure. 15

16 Impacts of these attacks are so high because firms are unprepared for response and recovery from these cyberattacks, here are some lessons learned 1 Get yourselves Match Fit Build a response plan with the right workflow Partner with industry experts that can help in time of need to quickly analyze the situation, handle crisis communication and work with law enforcement. Also required are experts that can quickly recover of all of the technology & assets to restore business operations. Practice 3 4 DR vulnerabilities must be fixed The DR capability is also affected by the cyberattack Unarticulated DR planning assumptions, e.g. AD is available What is the backup for the backup? Meet the challenge of scale Unrealistic DR tests and not for cyberattack scenarios Very labour intensive and long recovery Need for DR Automation and Orchestration 2 Cyber resiliency is a team sport Organizational alignment required gap between Security and DR DR functions mitigating traditional BC/DR risks, not recovery from cyberattack 5 Look out for Industry 4.0 / OT Supply Chain NotPetya attacked via a trusted supplier WannaCry impact on NHS via imaging and analysis equipment Back versions in OT systems.
