1 IBM and Security in the Healthcare Industry Information Security: Why is it important for the Healthcare Industry? Glen Gooding IBM Security Leader May

2 Baseline definitions Security For purposes in the context of IT security, a number of points need to be addressed Confidentiality - Integrity Availability - Authentication Authorisation - Audit CIA - AAA Privacy - Privacy means an individual's interest in limiting who has access to personal health care information. 2

3 How much security is enough (but not too much) From a security perspective, all IT solutions must balance three conflicting factors: The risk to the organisation of operating the IT solution The cost of implementing and operating the security controls in general, the tighter the controls the lower the risk The usability of the solution in general, the tighter the controls, the greater the impact on the users of the system RISK High Low High Low COST Low Security Environment USABILITY The resulting set of controls must be, as far as possible necessary and sufficient. Hig h Later will hear COST COMPLEXITY COMPLIANCE 3

4 IT Security is about CIA Confidentiality Integrity Availability 4

5 Data confidentiality Definition To protect against an unauthorised disclosure of the message. Technically Think encryption, SSL, the lock on your browser Health Care Specific Secure Messaging 5

6 Data integrity Definition Guarantee that the content of the data has not been tampered with. Technically Think Data signatures and the signing of data Health Care Specific Secure Messaging 6

7 Authentication Determines or proves that you are who you say you are Authentication based upon something you: know (e.g. password, PIN) Too many to remember Too easily guessed Can be sniffed/captured Can be cracked have (e.g. smart card, token) more expensive to deploy less portable are (e.g. biometrics) even more expensive to deploy may be considered invasive error-prone (false pos / neg) Health Care Specific HI, NASH 7

8 Authorisation Authorisation determines what an entity is allowed to do. Access control is a means of enforcing this authorisation model: data not disclosed data not modified users remain accountable. Health Care Specific Clinical applications, HR systems, Financials, Patient Administration 8

9 Audit Companies need to audit their IT infrastructure Determine whether or not business can continue to grow and mature based on current IT infrastructure Audit logs are often the only record that suspicious behaviour is taking place Can be fed real-time directly into intrusion detection or log management systems. Logs can provide individual accountability by tracking a user's actions. Logs are useful in reconstructing events after a problem has occurred, security related or not 9

10 Why is security important? Never fly in a plane designed by an optimist. 10

11 IBM Security Framework Built to meet four key requirements: Provide Assurance Enable Intelligence Automate Process Improve Resilience Introducing the IBM Security Framework and IBM Security Blueprint to Realise Business-Driven Security; IBM RedGuide REDP , July

12 Typical Client Security Requirements People and Identity Privileged user monitoring, including logging activities, physical monitoring and background checking Federated identity / on-boarding: Coordinating authentication and authorisation with enterprise or third party systems Standards-based SSO Data and Information Data segregation Client control over geographic location of data Government: Cloud-wide data classification Network, Server, Endpoint Isolation between tenant domains Trusted virtual domains: policy-based security zones Built-in intrusion detection and prevention Vulnerability Management Protect machine images from corruption and abuse Government: MILS-type separation Governance, Risk Management, Compliance 3rd-party audit (SAS 70(2), ISO27001, PCI, HIPAA) Client access to tenant-specific log and audit data Effective incident reporting for tenants Visibility into change, incident, image management, etc. SLA s, option to transfer risk from tenant to provider Support for forensics Support for e-discovery Application and Process Application security requirements are phrased in terms of image security Compliance with secure development best practices Physical Monitoring and control of physical access Based on interviews with clients and various analyst reports 12

13 Security governance, risk management and compliance IBM Security Framework Customers require visibility into the security posture of their environment. Implement a governance and audit management program Establish 3rd-party audits (ISO27001, PCI) 13 Provide access to log and audit data Create effective incident reporting Visibility into change, incident, image management, etc. Create policies for PII and for data crossing International boundaries Understand applicable regional, national and international laws Support for forensics and e-discovery

14 People and Identity IBM Security Framework Customers require proper authentication of all users. Implement strong identity and access management Implement least privilege model for user s access Strong Identity lifecycle management All administrative access over secure channels Privileged user monitoring, including logging activities, physical monitoring and background checking Utilise federated identity to coordinate authentication and authorization with enterprise or third party systems A standards-based, single sign-on capability 14

15 Data and Information IBM Security Framework Customers cite data protection as their most important concern. Ensure confidential data protection Protect PII and Intellectual Property Implement a secure key management program Use a secure network protocol when connecting to a secure information store Implement a firewall to isolate confidential information, and ensure that all confidential information is stored behind the firewall Sensitive information not essential to the business should be securely destroyed 15

16 Application and Process IBM Security Framework Customers require secure applications and provider processes. Establish application and environment provisioning Implement a program for application and image provisioning. Ensure provisioning management is strictly controlled Protect machine images from corruption and abuse Ensure all changes to virtual images and applications are logged. Ensure provisioned images apply appropriate access rights Ensure destruction of outdated images 16

17 Network, Server and End Point IBM Security Framework Customers expect a secure cloud operating environment.. Maintain environment testing and vulnerability/intrusion management Implement vulnerability scanning, anti-virus, intrusion detection and prevention on all appropriate images IBM Cloud Security Guidance Document 17 Ensure isolation exists between tenant domains Trusted virtual domains: policy-based security zones A secure application testing program should be implemented. Develop all Web based applications using secure coding guidelines. Ensure external facing Web applications are black box tested

18 Physical Security IBM Security Framework Customers expect health based data centers to be physically secure.. Implement a physical environment security plan Ensure the facility has appropriate controls to monitor access Prevent unauthorised entrance to critical areas within facilities e.g. servers, routers, storage, power supplies Biometric access of employees Ensure that all employees with direct access to systems have full background checks Provide adequate protection against natural disasters 18

19 The IBM Health Integration Framework Architectural blueprints for provider and payer transformation Pre-built healthcare accelerators Built on a Smart SOA TM foundation Keep up with open standards Leverage an ecosystem of key business partners Leverage existing healthcare applications, systems and business processes Healthcare Provider Solutions Rapid Development & Integration Lowered Risk and Cost Business Partner Ecosystem Health Integration Framework Process Flexibility Interoperability Infrastructure and Governance Intelligence Reduced Manual Intervention Speed accelerate delivery and integration Flexibility grow and add new capabilities incrementally Choice multiple solution on-ramps and business partners 19

20 Healthcare Identity, Access and Audit Management IBM's approach is to strategically manage risk end-to end across all risk areas within an organisation. Identity Manager Identity Management User Compliance Auditing Security Info and Event Mgr Access Management Unified Single Sign-On Enables visibility into user activity, control over access to PHI, and automation of the sign-on process in order to improve quality of care, clinician productivity, and overall compliance 20

21 I promised earlier that you would hear... COST High High Low Low Low Security Environment Hig h RISK USABILITY COST COMPLEXITY COMPLIANCE COST High High Low Low Low Security Environment Hig h RISK USABILITY 21

22 Reduce Complexity Scenario: Improve service by expanding reach via role based portals to services and applications Quickly roll out new applications and services to authorised users Enable single sign on for authentication Issue and manage user credentials Users role will determine the information and services they are authorised to access Monitor, audit and report on user activity Physician Portals Patient Portals Hospital Website/ Portals 22 Payer Portals

23 Reduce Cost Scenario: Reduce costs with self service and service management integration Offering user self-service to manage profile, passwords and access can reduce help desk, IT administration and user productivity costs By enabling users to manage passwords via challenge/response questions Rapid access to applications By accelerating time to access applications and sharing of workstations and kiosks By reducing labor required to manage and audit application-specific password policies via single sign-on Fast user switching Integrating identity management with incident management can reduce IT costs Offload service desk workload with selfservice password, profile management and access request Automate incident resolution within Tivoli Service Request Manager Tivoli Service Request Catalog Tivoli Identity Manager Self-Service 23

24 Manage Compliance Scenario: Manage risk of insider threat and support audit requirements with access recertification, user activity monitoring and reporting Monitor user access Do user access rights match responsibilities? Are rights consistently certified? Are there separation of duty violations? Monitor user activity Volume of activity Type & location of activity Timing of activity Privileged user activity Compliance Reporting Pre-built reporting modules on common regulatory mandates (SOX, PCI, Basel II, HIPAA, etc.) Flexible report design to match company-specific audit requirements 24

Secure access to applications, information and data while still allowing easy access for those with need and authority. Consistently enforce and audit corporate security and compliance policy. Streamline provisioning processes to facilitate quick access to clinical systems for staff. Reduce operational expenses through automation of common administrative tasks and providing service catalog components for those that make business sense. 28 Enable remote physician Web portal access to key data securely. 28

29 IAA for Healthcare - Business Case Summary Business Need Healthcare IT facilitates access to patient confidential data that is used to enable clinical care. Many Providers are faced with no central control of Identity provisioning. Security audits are central to local regulations Joint Commission compliance. Client Value Proposition Identity and Access Assurance allows the provider tighter control over their HIT infrastructure Know who is accessing which systems Know when their staff is accessing the systems Implement measures to assure a consistent audit trail procedure over security access. The business can depend on Identity and Access Assurance for Healthcare Providers Content exists to enable HIPAA compliance reporting in the solution. HIT ISV are partnering with IBM to develop provisioning adapters to their application suites. Enterprise Single Sign on with multifactor authentication can be deployed. Services Delivery and Deployment Strategy IBM Business Partners with Service Management experience can be engaged. Gold Coast Security Lab Services can be engaged for architectural guidance 29
