FIPS 201 / PIV

  1. 1. PIV (FIPS 201) Anshuman Sinha
  2. 2. What is PIV (FIPS 201)? <ul><li>Response to HSPD-12. “ Policy for a common identification standard for Federal Employees and Contractors. ” </li></ul><ul><li>Common Identity Standards For Federal Employees and contractors to get physical as well as logical access to Federal assets or Information Systems </li></ul><ul><li>Graduated security to different assurance levels for different applications. Too much of security may be expensive and redundant. </li></ul>Anshuman Sinha <anshuman.sinha2@gmail.com>
  3. 3. What does PIV replace? <ul><li>Drivers license as Identity of the Federal Employee and contractor </li></ul><ul><ul><ul><li> </li></ul></ul></ul><ul><ul><ul><li>=> => </li></ul></ul></ul><ul><li>Passwords to gain access to a service of or data in information system </li></ul><ul><ul><ul><ul><li>“ xxxxxxyyyy ” => </li></ul></ul></ul></ul>Anshuman Sinha <anshuman.sinha2@gmail.com>
  4. 4. Goals of PIV? <ul><li>Strong verification before issuance of Identity credentials, done by Issuance System or Card Mgmt. System </li></ul><ul><li>Authenticate rapidly and electronically which means paperless issuance.

  36. 36. Upon Lost Notification [Person in Organization] <ul><li>CMS should provide mechanism to block the card. The lost card should be promptly blocked. Host will need to have an interface which will notify the CMS that the card is lost -> therefore block it. </li></ul><ul><li>Host needs to inform about the lost or stolen card and request to generate a new card. </li></ul><ul><li>Credentialing organization receives the request and processes it to generate another plain card with platform keys that is sent to the card issuer. </li></ul>Anshuman Sinha <anshuman.sinha2@gmail.com>
  37. 37. Temporary Badge Creation <ul><li>Need to generate an emergency badge for the interim. The expiration date should be short, exact length is not specified, depends on the type of employee and agency ’ s policy regarding the same. </li></ul><ul><li>PIV doesn ’ t specify the type of temporary badge. For physical access, a visitor badge may suffice, but for logical access? </li></ul>Anshuman Sinha <anshuman.sinha2@gmail.com>
  38. 38. ReIssuance of PIV Credentials <ul><li>Go through the approval process again </li></ul><ul><ul><ul><li>Approval from signature authority </li></ul></ul></ul><ul><ul><ul><li>Determine turnaround time and notify card holder about it </li></ul></ul></ul><ul><ul><ul><li>Adjudication and Vetting process </li></ul></ul></ul><ul><ul><ul><li>Determine if card centralized/decentralized policy will be used </li></ul></ul></ul><ul><ul><ul><li>Develop materials/ handling requirements of card stock </li></ul></ul></ul><ul><ul><ul><li>Define Activation Policies </li></ul></ul></ul>Anshuman Sinha <anshuman.sinha2@gmail.com>
  39. 39. New / Replacement Badge Creation <ul><li>Format the badge with new set of keys and certificates. Since the badge is lost, new credentials are needed. </li></ul><ul><li>Increment the “ ICI ” (Individual Credential Issue Number), all physical access controllers should have the new ICI. </li></ul><ul><li>Usually its best idea to check every badge ’ s ICI. If not, the distinction could be done in credential number </li></ul>Anshuman Sinha <anshuman.sinha2@gmail.com>

  42. 42. 200 bit Weigand (FASCN) <ul><li>This format outputs the entire FASC-N. </li></ul><ul><ul><li>Example of FASC-N: </li></ul></ul><ul><ul><li>AC (agency code – 4 digits): 1111 </li></ul></ul><ul><ul><li>SC (site code – 4 digits): 2222 </li></ul></ul><ul><ul><li>C# (credential number – 6 digits): 333333 </li></ul></ul><ul><ul><li>CS (credential series – 1 digit): 4 </li></ul></ul><ul><ul><li>ICI (individual credential issue – 1 digit): 5 </li></ul></ul><ul><ul><li>PI (person Identifier – 10 digits): 6666666666 </li></ul></ul><ul><ul><li>0C (organizational category – 1 digit): 7 </li></ul></ul><ul><ul><li>OI (organizational identifier – 4 digits): 8888 </li></ul></ul><ul><ul><li>POA (person/organization association – 1 digit): 9 </li></ul></ul>Anshuman Sinha <anshuman.sinha2@gmail.com>
  43. 43. 200 bit Weigand (FASCN + E.Date) <ul><li>This format outputs the FASC-N with the expiration date.
