INTRODUCTION The Federal Risk and Authorization Management Program (FedRAMP) Program Management Office (PMO) prepared this document to provide guidance for completing the Plan of Action and Milestones (POA&M) Template. The POA&M is a key document in the security authorization package. It describes the specific tasks the Cloud Service Provider (CSP) has planned to correct any weaknesses or deficiencies in the security controls noted during the assessment and to address the residual vulnerabilities in their cloud system. CSPs applying for a FedRAMP Joint Authorization Board (JAB) Provisional Authorization to Operate (P-ATO) should use this guide while completing the POA&M Template, which is available at: http://www.fedramp.gov/resources/templates-3/. CSPs develop the POA&M document in the POA&M Template according to the rules and requirements described in this guide to ensure consistency across providers. The POA&M Template provides the required format for preparing the Plan of Action and Milestones. The CSP may add to the format as necessary to comply with its internal policies and FedRAMP requirements; however CSPs are restricted from altering columns or headers. 1.1. PURPOSE The purpose of the POA&M is to facilitate a disciplined and structured approach to mitigating risks in accordance with the CSP’s priorities. The POA&Ms include the findings and recommendations of the security assessment report and the continual security assessments. FedRAMP uses the POA&M to monitor progress in correcting weaknesses or deficiencies noted during the security control assessment and throughout the continuous monitoring process. The POA&Ms are based on the: § Security categorization of the cloud information system § Specific weaknesses or deficiencies in deployed security controls § Importance of the identified security control weaknesses or deficiencies § Scope of the weakness in systems within the environment § Proposed risk mitigation approach to address the identified weaknesses or deficiencies in the security controls (for example, prioritization of risk mitigation actions, allocation of risk mitigation resources) The POA&M identifies: (i) the tasks the CSP plans to accomplish with a recommendation for completion either before or after information system implementation; (ii) any milestones the CSP has set in place for meeting the tasks; and (iii) the scheduled completion dates the CSP has set for the milestones. |1 1.2. SCOPE The scope of the POA&M includes security control implementations (including all management, operational, and technical implementations) that have unacceptable weaknesses or deficiencies. The POA&M also includes an up-to-date list of assets within the environment, based on the list provided in the security assessment plan. CSPs are required to submit updated POA&Ms to the Authorizing Official (AO) in accordance with the FedRAMP Continuous Monitoring Strategy & Guide. 2. POA&M TEMPLATE CSPs gather and report basic system and weakness information in the POA&M Template. The POA&M Template is an Excel Workbook containing three worksheets: The current system POA&M worksheet, the closed (mitigated) POA&M worksheet, and an up-to-date System Inventory worksheet. CSPs should complete the System Inventory worksheet first because the Asset Identifier in the POA&M worksheet refers to the inventory items. 2.1. WORKSHEET 1: OPEN POA&M ITEMS The Open POA&M Items worksheet has two sections. The top section of the worksheet documents basic system information and tracks the headers described in the table below: Table 1 – POA&M Items Header Information Description HEADERS DETAILS CSP The Vendor Name as supplied in the documents provided to the AO. System Name The Information System Name as supplied in the documents provided to the AO. Impact Level Systems are categorized as Low, Moderate, or High based on a completed FIPS 199/800-60 evaluation. FedRAMP currently supports Moderate and Low risk impact level systems. POA&M Date The date the POA&M was created, which is the date the CSP committed to in their continuous monitoring plan. The bottom section of the Open POA&M Items worksheet is the corrective action plan used to track IT security weaknesses. This section of the POA&M worksheet has some similarities to the National Institute of Standards and Technology’s (NIST) format requirements, but requires additional data and formatting as required by FedRAMP. |2 Table 2 – POA&M Items Column Information Description HEADERS DETAILS Column A – POA&M ID Assign a unique identifier to each POA&M item. This can be in any format or naming convention that produces uniqueness, but FedRAMP recommends the convention V. (for example, V-123) Column B – Controls Specify the FedRAMP security control affected by the weakness identified during the security assessment process. Column C – Weakness Name Specify a name for the identified weakness that provides a general idea of the weakness. Use the Weakness Name provided by the security assessor, or taken from the vulnerability scanner that discovered the weakness. Column D – Weakness Description Describe the weakness identified during the assessment process. Use the Weakness Description provided by the security assessor or the vulnerability scanner that discovered the weakness. Provide sufficient data to facilitate oversight and tracking. This description should demonstrate awareness of the weakness and facilitate the creation of specific milestones to address the weakness. In cases where it is necessary to provide sensitive information to describe the weakness, italicize the sensitive information to identify it and include a note in the description stating that it is sensitive. Column E – Weakness Detector Source Specify the name of the Third Party Assessment Organization (3PAO), vulnerability scanner, or other entity that first identified the weakness. In cases where there are multiple 3PAOs, include each one on a new line. Column F – Weakness Source Identifier Often the scanner/assessor will provide an identifier (ID/Reference #) that specifies the weakness in question. This allows further research of the weakness. Provide the identifier, or state that no identifier exists. Column G – Asset Identifier List the asset/platform on which the weakness was found. This should correspond to the Asset Identifier for the item provided in Worksheet 3, Inventory List, as well as any applicable network ports and protocols. Include a complete Asset Identifier for each affected asset. Do not use an abbreviation or “shorthand”. The CSP may obfuscate the asset information when it is required by the internal policies of the CSP. The Asset Identifier must be unique and consistent across all POA&M documents, 3PAOs, and any vulnerability scanning tools. See Section 2.3 for formatting requirements. Column H – Point of Contact Identify the person/role that the AO holds responsible for resolving the weakness. The CSP must identify and document a Point of Contact (POC) for each reported weakness. Column I – Resources Required Identify any cost associated with resolving the weakness and provide an estimated staff time in hours. Column J – Overall Remediation Plan Provide a high-level summary of the actions required to remediate the plan. In cases where it is necessary to provide sensitive information to describe the remediation plan, italicize the sensitive information to identify it and include a note in the description stating that it is sensitive. Column K – Original Detection Date Provide the month, day, and year when the weakness was first detected. This should be consistent with the Security Assessment Report (SAR) and/or any continuous monitoring activities. The CSP may not change the Original Detection Date. Column L – Scheduled Completion Date The CSP must assign a completion date to every weakness that includes the month, day, and year. The Scheduled Completion Date column must not change once it is recorded. |3 HEADERS DETAILS Column M – Planned Milestones Each weakness must have a milestone entered with it that identifies specific actions to correct the weakness with an associated completion date. Planned Milestone entries shall not change once they are recorded. Column N – Milestone Changes List any changes to existing milestones in Column M, Planned Milestones in this column. Column O – Status Date This column should provide the latest date an action was taken to remediate the weakness or some change was made to the POA&M item. Column P – Vendor Dependency This column should specify whether the remediation of the weakness requires the action of a third party vendor. Should a weakness be vendor dependent, a monthly update with the third party vendor is required. In these cases, the weakness cannot be remediated, and the POA&M item cannot be closed, but the completion date may be extended if a monthly update is made. If the completion date is extended, provide an update in Column N, Milestone Changes. Once a patch is available, the CSP has 30 days to remediate high vulnerabilities and 90 days to remediate moderate vulnerabilities according to FedRAMP standards. This timeframe begins on the date that the patch is released. The CSP must include the patch release date in column Z (comments). In this case, the CSP may overwrite the auto-calculated scheduled completion date found in column L. Column Q – Last Vendor Check-in Date If the remediation of the weakness is dependent on a third party vendor’s action, as specified in Column P, Vendor Dependency; a monthly update with the third party vendor is required. Provide the date that the latest update was made. Column R – Vendor Dependent Product Name If the remediation of the weakness is vendor dependent, provide the name of the product for which the third party vendor has responsibility. Column S – Original Risk Rating Provide the original risk rating of the weakness at the time it was identified as part of an assessment and/or continuous monitoring activities. Column T – Adjusted Risk Rating Provide the adjusted risk rating when a Deviation Request Form is submitted. If no risk adjustment is made, state N/A. In the case that the scanner changes its risk rating from a lower to higher risk rating, the CSP may update this column and set column U to “Yes.” No deviation request form is necessary in this case. Column U – Risk Adjustment State the status of the risk adjustment request. CSP determination of a risk adjustment will cause this column to be set to “pending”. The adjustment is finalized (setting the Risk Adjustment to “yes”) if it is approved by the AO. Approved risk adjustments may alter the scheduled completion date. Column V – False Positive State the status of the weakness deviation request for false positive. A False Positive (FP) occurs when a vulnerability is identified that does not actually exist on the system. For example, a vulnerability scanner may incorrectly identify a weakness that is not installed, or not completely identify a recent system update. Either the scanner is incorrect, or it has not found a completed system update. A false positive means the weakness is determined to be non-existent and is a false positive provided by the vulnerability scanner. A CSP determination of a false positive will cause this column to be set to “pending”, the deviation is finalized (setting the status to “yes”) if it is approved by the AO. Approved false positives can also be closed, see Section 2.2 for guidance on closing a POA&M item. |4 HEADERS DETAILS Column W – Operational Requirement State the status of the weakness deviation request for operational requirement. An Operational Requirement (OR) means that there is a weakness in the system that will remain an open vulnerability that cannot be corrected without impacting the full operation of the system. An OR is also an open vulnerability that could be exploited (regardless of the limited opportunity for exploitation), such as a component that is installed but not enabled. A CSP determination of an operational requirement will cause this column to be set to “pending”, the deviation is finalized (setting the status to “yes”) if it is approved by the AO. Approved operational requirements remain on Worksheet 1, POA&M Template, and are to be periodically reassessed by the CSP. Column X – Deviation Rationale Provide a rationale for the various weakness deviations requested, including mitigating factors and compensating controls that address the specific risk to the system. For False Positives, include information about evidence/artifacts that support the result. Column Y – Supporting Documents List any additional documents that are associated with the POA&M item. Column Z – Comments Provide any additional comments that have not been provided in any of the other columns. 2.2. WORKSHEET 2: CLOSED POA&M ITEMS The Closed POA&M Items worksheet contains similar basic system information as the top of Worksheet 1, Open POA&M Items. The remainder of the document should contain the POA&M items that are completed. The details will reflect almost all of the information provided in the Open POA&M Items worksheet; however Column O, Status Date, needs to be updated to the date of completion. To “close” a POA&M item, update the date in Column O, Status Date and move the POA&M item to Worksheet 2, Closed POA&M items. A POA&M item can be moved to the Closed POA&M Items when either of the following occurs: § All corrective actions have been applied and evidence of mitigation has been provided. Evidence of mitigation can be verification by a 3PAO, a targeted vulnerability scan that covers the weakness domain, the following continuous monitoring scans, etc. § A false positive request was submitted and approved by the AO. 2.3. INTEGRATED INVENTORY WORKBOOK As indicated above, CSPs may append their current Integrated Inventory Workbook Template (a separate FedRAMP Template) as an additional worksheet (worksheet 3) within the POA&M Template or may retain the Integrated Inventory Workbook Template as a separate document, as desired. While the Integrated Inventory Workbook Template is initially submitted and |5 referenced in the SSP/SAP/SAR and other applicable documents as part of the initial assessment, it must be updated and submitted regularly with the POA&M, as part of continuous monitoring in accordance with the FedRAMP Continuous Monitoring Strategy & Guide. Please see the Integrated Inventory Workbook Template for instructions on completing and updating the inventory of system assets. The FedRAMP Integrated Inventory Workbook Template can be found on the following FedRAMP website page: Templates. 3. GENERAL REQUIREMENTS POA&Ms must include all known security weaknesses within the cloud information system. POA&Ms must comply with the following: § Use the POA&M Template to track and manage POA&Ms. § If a finding is reported in the SAR and/or in the continuous monitoring activities, the finding must be included as an item on the POA&M. § All findings must map back to a finding in the SAR and/or any continuous monitoring activities § False positives identified in the SAR (Appendices C, D, and E), along with supporting evidence (for example, clean scan report) do not have to be included in the POA&M. § Each line item on the POA&M must have a unique identifier. This unique identifier should pair with a respective SAR finding and/or any continuous monitoring activities. § All high and critical risk findings must be remediated prior to receiving a Provisional Authorization. § High and critical risk findings identified following Provisional Authorization through continuous monitoring activities must be mitigated within 30 days after identification. § Moderate findings shall have a mitigation date within 90 days of Provisional Authorization date or within 90 days of identification as part of continuous monitoring activities. § The POA&M must be submitted in an appropriate format for the FedRAMP automated processes. See the example row in the POA&M Template. Note: The POA&M Spreadsheet has problems with data validation in the Mac version of Microsoft Office. Disabling macros should prove to be a sufficient work-around. |6 APPENDIX A: FedRAMP ACRONYMS The master list of FedRAMP acronym and glossary definitions for all FedRAMP templates is available on the FedRAMP website Documents page under Program Overview Documents.
