8 The Key Business Challenges 8

9 The Key Technology Challenges 9

10 The Threat Situation Continuing serious cyber attacks on information systems, large and small; targeting key federal, state, local, and private sector operations and assets. Threat Actors Attacks are organized, disciplined, aggressive, and well resourced; many are extremely sophisticated Adversaries are nation states, terrorist groups, criminals, hackers, and individuals or groups with intentions of compromising your information systems Effective deployment of malicious software causing significant exfiltration of sensitive information (including intellectual property) and potential for disruption of critical information systems / services. -- Dr. Ron Ross NIST, Computer Security Division Information Technology Laboratory 10

18 The Challenge: To Corporate and Government Leaders. Where does your business stand on basic cybersecurity hygiene? There is a global awakening among non technologists That we are vulnerable in cyberspace We are not organized well to protect ourselves We suffer from a fog of more More standards, more checklists, more devices, more technology, more things Our Executives need to ask five basic questions Do we know what s connected to our systems and networks? Do we know what s running or trying to run on our systems and networks? Are we limiting the number of people with administrative privileges to change, bypass or override the security setting? Do we have continuous processes backed by security technologies that allow us to prevent most breaches, rapidly detect all that do succeed and minimize damage to our business and customers? Can you demonstrate all this to me, to our Board, and to our shareholders and customers today? Because. Having these basic safeguards in place will prevent 80% to 90% of the known attacks Jane Holl Lute Council on Cybersecurity Served as Deputy Secretary for Homeland Security from April, 2009 to April

19 The Response: We Need to be Proactive. Manage our Risks Understand and establish a well developed risk management model Apply controls to our assets Because every security incident starts with a compromised asset Manage our Assets Inventory, prioritize, categorize (by type and value), safeguard Lifecycle Management (provision, de-provision, discover, manage changes, reconciliation, monitor & alert Manage our Programs Understand the essential building blocks And how they relate Alignment and Transparency Are we on the same page? Are we learning and improving? Are we testing and measuring? Are we maturing our program over time? 19

20 We have executive attention.. So now what? 20

21 Part 2: Understanding the Risks 21

22 The Risk Equation Risk = Threats X Vulnerabilities X Asset Value + Residual Risk Controls How do we calculate risk? Risk is based on the likelihood and impact of a cyber-security incident or data breach Threats involve the potential attack against IT resources and information assets Vulnerabilities are weaknesses of IT resources and information that could be exploited by a threat Asset Value is based on criticality of IT resources and information assets Controls are safeguards that protect IT resources and information assets against threats and/or vulnerabilities Residual risk includes a combination of unknown threats + unknown vulnerabilities + unmanaged assets + missing controls 22

23 Assets: What are you trying to protect? What are the assets? Where are the Assets? How are the Assets Managed? Which Assets are Critical? 23

24 Threats: What are you afraid of happening? What are the threats? Where are the threats? How have the threats changed? How are attacks staged? 24

25 Vulnerabilities: How could the threat occur? What is a vulnerability? What are the Vulnerabilities? How are the Vulnerabilities Managed? How are vulnerabilities remediated? 25

26 Mitigation: What is currently reducing the risk? What is a control? What is a controls framework? What are the controls types? How are controls measured?

36 The NIST Cybersecurity Framework Cybersecurity Program Steps The Cybersecurity Resilience Approach Step 1: Prioritize and Scope. Step 2: Orient. Step 3: Create a Current Profile. Step 4: Conduct a Risk Assessment. Step 5: Create a Target Profile. Step 6: Determine, Analyze, and Prioritize Gaps. Step 7: Implement Action Plan. 36

37 The NIST Cybersecurity Framework NIST Definition of cyber resilience the ability to prepare for and adapt to changing conditions and withstand and recover rapidly from disruptions. Resilience includes the ability to withstand and recover from deliberate attacks, accidents, or naturally occurring threats or incidents 37

38 DHS Cyber Resilience Review Areas of Focus 1 Asset Management - The purpose of Asset Management is to identify, document, and manage assets during their life cycle to ensure sustained productivity to support critical 2 Controls Management - The purpose of Controls Management is to identify, analyze, and manage controls in a critical service s operating environment. 3 Configuration and Change Management - The purpose of Configuration and Change Management is to establish processes to ensure the integrity of assets using change control and change control audits. 4 Vulnerability Management - The purpose of Vulnerability Management is to identify, analyze, and manage vulnerabilities in a critical service s operating environment. 5 Incident Management - The purpose of Incident Management is to establish processes to identify and analyze events, detect incidents, and determine an organizational response. 6 Service Continuity Management - The purpose of Service Continuity Management is to ensure the continuity of essential operations of services and their associated assets if a disruption occurs as a result of an incident, disaster, or other disruptive event. 7 Risk Management - The purpose of Risk Management is to identify, analyze, and mitigate risks to critical service assets that could adversely affect the operation and delivery of services. 8 External Dependencies Management - The purpose of External Dependencies Management is to establish processes to manage an appropriate level of controls to ensure the sustainment and protection of services and assets that are dependent on the actions of external entities. 9 Training and Awareness - The purpose of training and awareness is to promote awareness in and develop skills and knowledge of people in support of their roles in attaining and sustaining operational sustainment and protection. 10 Situational Awareness - The purpose of Situational Awareness is to actively discover and analyze information related to immediate operational stability and security and to coordinate such information across the enterprise to ensure that all organizational units are performing under a common operating picture. 38

65 Summary: Building an Effective Security Program The NIST Golden Rules Develop an enterprise-wide information security strategy and game plan Get corporate buy in for the enterprise information security program effective programs start at the top Build information security into the infrastructure of the enterprise Establish a level of due diligence for information security Focus initially on mission/business case impacts bring in threat information only when specific and credible Create a balanced information security program with management, operational, and technical security controls Employ a solid foundation of security controls first, then build on that foundation guided by an assessment of risk Avoid complicated and expensive risk assessments that rely on flawed assumptions or unverifiable data Harden the target; place multiple barriers between the adversary and enterprise information systems Be a good consumer beware of vendors trying to sell single point solutions for enterprise security problems Don t be overwhelmed with the enormity or complexity of the information security problem take one step at a time and build on small successes Don t tolerate indifference to enterprise information security problems And finally Manage enterprise risk don t try to avoid it! 65
