
A Crisis (Event) is Any Situation Requiring Regional,
National or International Attention as Determined by
the President of United States/UN
A Coalition is an Alliance of Organizations:
Governmental (Federal, State, and Local), Military,
Civilian, International or Combination
A Dynamic Coalition is Formed in a Crisis and
Changes as Crisis Develops, with the Key Concern
Being the Most Effective way to Solve the Crisis
Dynamic Coalition Problem (DCP) is the Inherent
Security, Resource, and/or Information Sharing Risks
that Occur as a Result of the Coalition Being Formed
Quickly

Tidal Wave in Southeast Asia
Hurricanes in US
 Katrina – Louisiana and Mississippi
 Rita – Texas and Louisiana
Mudslides in Guatemala
Earthquake in Pakistan/India
Key Issues for US Crises:
 Both Hurricanes Involved Large Populations of
Underinsured and Uninsured
 Rita had Notice – Evacuation Hampered/Slow
 Relief Hampered by Total Failure of Power,
Particularly in New Orleans
 Coalitions Difficult to Form and Utilize

Emergent Need for Coalitions

CSE
4701
“Coalitions must be flexible and no one coalition is or
has the answer to all situations.”
» Secretary of Defense, Donald Rumsfeld

“Whenever possible we must seek to operate alongside
alliance or coalition forces, integrating their
capabilities and capitalizing on their strengths.”
» U.S. National Security Strategy

“Currently, there is no automated capability for
passing command and control information and
situational awareness information between nations
except by liaison officer, fax, telephone, or loaning
equipment.”
» Undersecretary of Defense for Advanced Technology

Uninsured/Underinsured Patients are Difficult to
Manage/Treat from an Informatics Perspective
 Move from State Agency to Agency
 Visit Many Diverse Health Care Providers
 Incomplete/Inconsistent Data for Each Visit
Treatment of Chronic Diseases is Difficult
 Consider Asthma – Many Different Types,
Treatment Plans, Medication Regimes, etc.
 History, Symptoms, Past Meds, etc., all Vital to
Deal with Current Problem
 Problematic with Incomplete/Missing History
One Individual at a Time – What Happens when there
is a State-Wide Event that Impacts 10,000?

Dealing with Different Patient Populations?
Insured Populations:
 Less Dispersed Profile of Medical Visits
 Easier to Obtain Compete Patient Records
Underinsured/Uninsured Populations:
 Varied/Disparate Visit Profile
 Changing Addresses/Homeless
 Cycle Among State Agencies, Providers
 Higher Rates of Respiratory Illnesses
Coalitions Need to Deal with All Potential Patients
Difficulty with Underinsured/Uninsured Populations
Means Potential for Incorrect Care

Establish Roles to Information Repositories
 Responders, Emergency/Medical Personnel ...
 Coalitions Dynamic –Secure/Flexible Access
 Transcend HIPAA, Other Constraints
Time Controllable Access to Information
 Time Limits on Users and Roles
 As Event Abates, Access Becomes Stricter
Value Based Constraints on Access
 Multiple Events, Responders Limited Access
Difficult to Federate Users and Resources
 Proprietary Databases in Different Formats

GCCS Shortfalls: User Roles

CSE




Currently, GCCS Users have Static Profile Based on
Position/Supervisor/Clearance Level
Granularity Gives “Too Much Access”
Profile Changes are Difficult to Make - Changes Done
by System Admin. Not Security Officer
What Can User Roles Offer to GCCS?
 User Roles are Valuable Since They Allow
Privileges to be Based on Responsibilities
 Security Officer Controls Requirements
 Support for Dynamic Changes in Privileges
 Towards Least Privilege

Emergent Events (Chemical) Requires a Response
Some Critical Issues
 Who’s in Charge?
 Who is Allowed to do What?
 Who can Mobilize Governmental Resources?
Roles can Help:
 Role for Event Commander(s)
 Roles for Event Participants/Personnel
 Roles Dictate Control over Resources
For Katrina: Lack of Leadership & Defined Roles
 Army Corps of Engineers Only Allowed to Repair
Levees – Not Upgrade and Change

GCCS Shortfalls: Time Controlled Access

CSE


Currently, in GCCS, User Profiles are Indefinite with
Respect to Time
 Longer than a Single Crisis
 Difficult to Distinguish in Multiple Crises
 No Time Controllable Access on Users or GCCS
Resources
What can Time Constrained Access offer GCCS?
 Junior Planners - Air Movements of Equipment
Weeks before Deployment
 Senior Planners - Adjustment in Air Movements
Near and During Deployment
 Similar Actions are Constrained by Time Based on
Role

Multiple Events Require Ability to Distinguish
Between Roles Based on Time and Crisis
Occurrence of Rita (one Event) Impacted the Ongoing
Event (Katrina)
Need to Manage Simultaneous Events w.r.t. Time
 Different Roles Available at Different Times for
Different Events
 Role Might be “Finishing” in one Event (e.g., First
Response Role) and “Starting” in Another
 Individual May Play Different Roles in Different
Event
 Individual May Play Same Role with Different
Duration in Time w.r.t. its Activation
Chaps22-38
GCCS Shortfalls: Value Based Access

CSE
4701

Currently, in GCCS, Controlled Access Based on
Information Values Difficult to Achieve
 Unlimited Viewing of Common Operational
Picture (COP)
 Unlimited Access to Movement Information
 Attempts to Constrain would have to be
Programmatic - which is Problematic!
What can Value-Based Access Offer to GCCS?
 In COP
 Constrain Display of Friendly and Enemy Positions
 Limit Map Coordinates Displayed
 Limit Tier of Display (Deployment, Weather, etc.)

In Katrina/Rita, What People can See and Do May be
Limited Based on Role
 Katrina Responders Limited to Katrina Data
 Rita Responders Limited to Rita Data
 Some Responders (Army Corps Engineers) May
Need Both to Coordinate Activities
 For Chemical Event – Same Issue to Address
Within Each Event, Information Also Limited
 Some Katrina Roles (Commander, Emergency
Responders, etc.) see All Data
 Other Katrina Roles Limited (Security Deployment
Plans Not Available to All)
 Again – Customization is Critical

GCCS Shortfalls: Federation Needs

CSE


Currently, GCCS is Difficult to Use for DCP
 Difficult to Federate Users and Resources
 U.S. Only system
 Incompatibility in Joint and Common Contexts
 Private Network (Not Multi-Level Secure)
What are Security/Federation Needs for GCCS?
 Quick Admin. While Still Constraining US and
Non-US Access
 Employ Middleware for Flexibility/Robustness
 Security Definition/Enforcement Framework
 Extend GCCS for Coalition Compatibility that
Respects Coalition and US Security Policies

 How will that Access be Delivered?
 Who (People/Roles) will Need to See What When?
 How will What a Person Sees Impact Other
Sources?

Concerns: Consistency, Accuracy, Reliability
Accidental Errors – All too Prevalent
 Crashes, Concurrent Access, Logical Errors
 Actions:
 Integrity Constraints (Correct Data Values)
 GUIs (Correctly Entered Values)
 Redundancy (Values are Backed Up Offsite: 9/11)

Malicious Errors - Not Totally Preventable
 Individuals Seek to Interfere with Coalition
Operations During Actual Event
 Actions:
 Authorization, Authentication, Enforcement Policy
 Concurrent Updates to Backup DBs

Assurance
 Do Security Privileges for Each User Support their
Needs?
 What Guarantees are Given by the Security
Infrastructure in Order to Attain:
 Safety: Nothing Bad Happens During Execution
 Liveness: All Good Things can Happen During
Execution

Consistency
 Are the Defined Security Privileges for Each User
Internally Consistent?
 Are the Defined Security Privileges for Related
Users Globally Consistent?

What are Key Security Concepts?

CSE


Principal or Subject
 Entity (Person/Process/etc.) to Which
Authorizations are Granted
 Can be a User, User Group, Program, Client,
Protected Object (Chunk of Information)
 Known Object whose Internal Structure is
Inaccessible Except by Protection System
 The Unit of Protection
 For Our Purposes:
 Patient Record, Patient Test, etc.
 Geographic Database, Weather Map, etc.
Glossary from: Saltzer and Schroeder, “The Protection of Information in
Computer Systems”, Proc. of IEEE, Vol. 63, No. 9, September 1975.

What are Key Security Concepts?

CSE




Authentication
 Proving you are who you are
 Is the Client who S/he Says they are?
Authorization
 Granting/Denying Access to Information
 Revoking Access to Information
 Does the Client have Permission to do what S/he
Wants?
Encryption
 Establishing Communications so that No One but
Receiver Gets the Content of the Message
 Symmetric and Public Key Encryption
All Three are Vital for Coalitions/Events
Chaps22-57
What are Key Security Issues?

CSE
4701


Legal and Ethical Issues
 Information Must be Protected (e.g., SSN)
 Information Must be Accessible (e.g., Medical
Record)
Policy Issues
 Who Can See What Information When?
 Applications Limits w.r.t. Data vs. Users?
Access Control Models
 Govern the Way that Secure Access of Subjects to
Objects is Controlled
 Ranges from User (Roles) to Data Control
 Also Includes Ability to Delegate Capabilities
from One User to Another
Chaps22-58
Role Based Access Control

CSE
4701

What is Role Based Access Control (RBAC)?
 Roles Provide Means for Permissions to Objects,
Resources, Based on Responsibilities
 Users May have Multiple Roles Each with
Different Set of Permissions
 Role-Based Security Policy Flexible in both
Management and Usage
Issues for RBAC and DCP
 Who Creates the Roles?
 Who Determines Permissions (Access)?
 Who Assigns Users to Roles?
 Are there Constraints Placed on Users Within
Those Roles?
Chaps22-59
Discretionary Access Control

CSE
4701

What is Discretionary Access Control (DAC)?
 Restricts Access to Objects Based on the Identity
of Group and /or Subject
 Discretion with Access Permissions Supports the
Ability to “Pass-on” Permissions
DAC and DCP
 Pass on from Subject to Subject is a Problem
 Information Could be Passed from Subject (Owner) to
Subject to Party Who Should be Restricted

For Example,
 Local Commanders Can’t Release Information
 Rely on Discretion by Foreign Disclosure Officer

Pass on of DAC Must be Carefully Controlled!
Chaps22-60
Mandatory Access Control

CSE
4701

What is Mandatory Access Control (MAC)?
 Restrict Access to Information, Resources, Based
on Sensitivity Level (Classification) Classified
Information - MAC Required
 If Clearance (of User) Dominates Classification,
Access is Allowed
MAC and DCP
 MAC will be Present in Coalition Assets
 Need to Support MAC of US and Partners
 Partners have Different Levels/Labels
 Need to Reconcile Levels/Labels of Coalition
Partners (which Include Past Adversaries!)
