MEMORANDUM FOR CHIEF, AGENCY-WIDE SHARED SERVICES
FROM: Michael R. Phillips /s/ Michael R. Phillips
Deputy Inspector General for Audit
SUBJECT: Final Audit Report – The Internal Revenue Service Adequately Protected Sensitive Data and Restored Computer Operations After the Flooding of Its Headquarters Building (Audit # 200620041)
This report presents the results of our review to evaluate the actions taken by the Internal Revenue Service (IRS) in response to the flooding of its Headquarters building. Specifically, we determined whether the IRS adequately protected data and computer operations and sufficiently recovered its computer systems and data damaged or disrupted by the flooding. The Senate Finance Committee requested that the Treasury Inspector General for Tax Administration determine the extent and nature of disruption to IRS operations and identify the functions and locations that have been most affected as a result of the flooding. This audit is one of three reviews that the Treasury Inspector General for Tax Administration initiated to answer the Senate Finance Committee’s request.
Impact on the Taxpayer
The flooding disaster at the IRS Headquarters building in Washington, D.C., could have resulted in the loss of taxpayer data and disruption in computer operations. However, due to preparatory and responsive actions, the IRS adequately protected sensitive data in the aftermath of the flooding and restored computer operations for its Headquarters employees.
A rare tropical deluge over the Washington, D.C., metropolitan area on June 24 and 25, 2006, unleashed floods of water that swamped the Federal Triangle area of the nation’s capital and forced an estimated 3 million gallons of water into the basement and subbasement of the IRS Headquarters building at 1111 Constitution Avenue, NW. Due to cleanup activities, health concerns, and the lack of electricity and ventilation, the building was closed and could not be immediately reoccupied. The building reopened in December 2006. The Headquarters building houses more than 2,200 employees from various IRS business units, including many top-level management officials.
Taxpayer data stored in the entire building were adequately protected against the risk of unauthorized access. In addition, destroyed taxpayer data stored in the basement were properly protected and disposed of.
Perimeter security was always maintained at the Headquarters building, and entry was tightly controlled after the flooding occurred. As a result, taxpayer data stored in the entire building were adequately protected against the risk of unauthorized access. In addition, damaged equipment and destroyed taxpayer data stored in the basement were properly protected and disposed of.
A little more than 1 month after the flooding, the
Agency-Wide Shared Services Division had completed workstation space
arrangements for displaced employees in 15 different locations in the
The MITS organization restored computer infrastructure operations that existed in the Headquarters building prior to the flooding. A Wage and Investment Division computer application system, the only mainframe application operating out of the Headquarters building, was reestablished at a mainframe computer in another site within 2 calendar days after the flooding. Other critical servers were moved from the Headquarters building to another IRS facility and restored for availability to employees within 8 calendar days after the flooding. Many other vital servers were moved and restored within 2 weeks after the flooding.
We commend the efforts of the IRS and believe the actions taken by the IRS protected taxpayer data and minimized the disruption of computer operations caused by the flooding. However, we found the tracking of computer assets removed from the building was not initiated timely. For example, several Wage and Investment Division servers were removed from the Headquarters building without the knowledge or approval of the MITS organization. These servers were temporarily stored overnight in non-IRS space. Also, the Criminal Investigation Division removed many servers from the building before the asset tracking system was implemented.
MITS organization employees were unable to perform a physical inventory validation of computers remaining in the building because the building was closed. However, now that the building has reopened, the annual physical inventory validation is scheduled to begin in January 2007. We encourage the completion of this inventory validation because it will provide documented evidence that all computers are properly accounted for.
The Chief, Agency-Wide Shared Services, should ensure the Incident Management Plans for all IRS locations include the implementation of an asset tracking system and related processes immediately after a disaster.
The Chief, Agency-Wide Shared Services, agreed with our findings and recommendation. The Director, Agency-Wide Shared Services Employee Support Services, developed and implemented an Emergency Incident Asset Retrieval form, which has been incorporated into the Incident Management Plan Addendum. In addition, incident management planning was updated to include the asset tracking process, and training was provided to appropriate personnel. Management’s complete response to the draft report is included as Appendix IV.

A rare tropical deluge over the Washington, D.C., metropolitan area on June 24 and 25, 2006, unleashed floods of water that swamped the Federal Triangle area of the nation’s capital and forced the closure of many Federal Government offices, including the Internal Revenue Service (IRS) Headquarters building at 1111 Constitution Avenue, NW. Electrical and maintenance equipment in the subbasement of the building was submerged in more than 20 feet of water. Also, the basement of the building, which contained additional electrical equipment, a health fitness facility, stored records, computer equipment, and vehicles garaged in the building, was partially submerged.

The IRS Headquarters building houses more than 2,200 employees from various IRS business units. Among these employees are the top-level management officials, such as the Commissioner and Deputy Commissioners.
On July 6, 2006, the Assistant Secretary for Management, Department of the Treasury, met with the Treasury Inspector General for Tax Administration (TIGTA) and expressed concern about how the IRS was responding to the disaster. On July 12, 2006, the ranking member of the Senate Finance Committee sent a letter to the Inspector General requesting that the TIGTA determine the extent and nature of disruption to IRS operations and identify the functions and locations that have been most affected by the flooding. As a result, the TIGTA Office of Audit initiated three audits to answer concerns about the flooding disaster at the IRS Headquarters building. This review focused on data security and computer operations, while the objectives of the other reviews relate to general business resumption efforts and determining the costs related to the flooding disaster.
This review was performed at the IRS National Headquarters in Washington, D.C.; the IRS Office of Chief Counsel at 950 L’Enfant Place, Washington, D.C.; the New Carrollton Federal Building at 5000 Ellin Road, Lanham, Maryland; and the IRS Real Estate and Facilities Management office at 2221 South Clark Street, Crystal City, Virginia, during the period July through October 2006. The audit was conducted in accordance with Government Auditing Standards. Detailed information on our audit objective, scope, and methodology is presented in Appendix I. Major contributors to the report are listed in Appendix II.
The flooding into the IRS’ Headquarters building occurred on Sunday evening, June 25, 2006. The building was unoccupied at the time except for the usual security guards posted at the perimeter. A short-circuit in the electrical system caused by the flooding set off the fire alarm at 10:45 p.m., and a security guard contacted the IRS building manager. The building manager promptly went to the building to assess the situation. At that point, Constitution Avenue was under 3 feet of water. Within 2 hours of arriving, the building manager had arranged for water pumps to begin pumping water out of the basement. On Monday, June 26, 2 other firms, 1 under contract by the General Services Administration and another under contract by the IRS, joined the first group in the removal of an estimated 3 million gallons of water.
The IRS building manager notified the Incident Commander of the flooding at 12:45 a.m. on Monday, June 26, 2006, and the Incident Commander contacted key management officials to advise them of the flooding and that the building would be closed for the day. At 3:01 a.m., the Incident Commander authorized a message to be sent to all IRS executives advising them of the flooding of the building. The Incident Commander enlisted the support of the IRS Communications Officer to contact the local media. By 3:37 a.m., all local television channels and a radio station had been contacted for public notification of the building closure. The announcement on the radio also included a contact telephone number for employees to call for additional information. In addition, a voice mail message was issued to all IRS District of Columbia employees advising them of the closure of the building for the day, and the IRS’ official web site provided current information on the building closure. Also, on June 26, 2006, senior IRS leadership established operations in another local IRS building in accordance with the IRS Business Resumption Plan.
As the water receded, it became apparent that all contents located in the basement had been damaged or destroyed. Doors had been forced from their hinges, some of the windows were broken, and furniture was piled into doorways. Many records were soaked and all computers were damaged. The highest water level in the basement reached approximately 5 feet. The water depth in the small subbasement, containing electrical and maintenance equipment, was estimated at 20 feet.
Perimeter security was maintained at the building, and entry was tightly controlled after the flooding occurred
In the days following the flooding, the IRS placed additional security guards to prevent any unauthorized entry into the building. Physical access into the building was controlled through a single entry point. All employees entering the building were required to sign in and out. By Wednesday, June 28, 2006, it was determined by the Incident Commander and senior IRS executives that the building would be closed for an extended period of time. Because the building was secure at all times, taxpayer data maintained throughout the building were not at risk of unauthorized access.
Damaged equipment and destroyed taxpayer data stored in the basement were properly protected and disposed of
Unsalvageable records stored in the basement included over 100 boxes containing taxpayer and other personally identifiable information belonging to the Office of Chief Counsel and the Office of the Tax Exempt and Government Entities Division, personnel records of the Criminal Investigation (CI) Division, employee medical records maintained by the Health Unit, and Freedom of Information Act litigation documents. Based on potential health and contamination issues caused by the floodwaters and the fact that many of the documents with long-term retention periods were replicated in the records of United States District Attorneys and United States District Courts, the National Archives Records Administration approved the destruction of these records. On July 12, 2006, these records were destroyed by the document destruction company currently under contract with the IRS.
Employees of the primary cleaning contractor normally used by the IRS from an existing contract had been screened for suitability of employment; however, the additional 100 employees used for the emergency cleanup after the flood worked for a subcontractor and did not have security clearances. Cleaning of the flooded building was conducted around the clock, with the subcontractor employees working 12-hour shifts. These employees were required to sign in and out of the building and were restricted to the basement area. In addition, the primary contractor employees and the security guards on duty at the building monitored the cleaning activities. Given these circumstances and mitigating controls in place, we believe the use of unscreened contractors was appropriate to expedite cleanup efforts.
In addition to hardcopy files, Building Management function employees and contractors with offices in the basement had computers that were destroyed. These computers did not contain taxpayer information. The CI Division had three computers in the basement, one of which was used to issue credentials. The three damaged CI Division computers were taken to the CI Division laboratory for security purposes. The CI Division also had 12 new, unused notebook computers damaged by the flood. In addition, the Office of Chief Counsel had $1.3 million of new, unused computer equipment stored in the basement. None of the new equipment contained taxpayer data. The new computers were disposed of by the contractor responsible for cleaning the basement area.
Tracking of computer assets removed from the building was not initiated timely, and computers were allowed to be taken out of the building without proper oversight and accountability
While the flooding disaster mainly affected the basement and subbasement floors, it indirectly affected the rest of the building because all electrical and ventilation equipment was damaged and would take months to repair or replace. In addition, summer weather temperatures and high humidity levels created concern about contamination and mold growth in the building. As a result, the entire building was closed and deemed unsuitable for employee occupancy.
To expedite the resumption of normal operations, the IRS allowed limited and escorted traffic into the building after the flooding. To account for and control building traffic, all persons entering and leaving the building were required to sign in and out. Employees were permitted to enter the building and remove personal items, files, and computers. For example, many employees who were assigned laptop computers entered the building to retrieve their computers. In some cases, IRS computer desktop support employees helped the employees pack their computers for shipment to the employees’ new work locations. Some of the larger desktop computers were removed, but most of these computers remained in the building. The IRS provided replacement computers for these users at their new locations. Procedures for tracking computer assets in the event of a disaster had not been included in the IRS’ Incident Management Plan.
By Friday, June 30, 2006, the IRS had developed and implemented an asset tracking process to track the removal of assets, including equipment and records from the IRS Headquarters building. Modernization and Information Technology Services (MITS) organization managers requested that no computer equipment be moved except under controlled and secure conditions. In addition, employees who had already removed items were asked to retroactively complete the asset tracking forms so inventory records would show the correct location for each item. To their credit, 148 employees completed the tracking forms, listing the equipment and items they had taken from the building between June 26 and June 29, 2006. According to these forms, 104 computers were removed, including 81 laptop computers. In total, employees removed 627 computers, including 464 laptop computers, from the Headquarters building.
· On Wednesday, June 28, 2006, seven servers from the Wage and Investment (W&I) Division were removed from the Headquarters building by contractors and placed in a locked room within a secure but non-IRS building overnight without the knowledge or approval of the MITS organization. ****3(d)**** When the removal of the servers was discovered the following day, the MITS organization directed the W&I Division to immediately move these servers to a designated IRS building and the move was completed that same day. Before these computers were reconnected to the IRS network, the IRS tested the computers to ensure compliance with IRS security standards. The servers have been tracked to their current location.
· On Wednesday, June 28, 2006, and Thursday, June 29, 2006, employees from the CI Division removed 41 computer servers from the Headquarters building using a rented truck. The CI Division was able to move the computers before the asset tracking system was in place because the Division has its own computer staff and did not need assistance from the MITS organization. Prior to the removal of the equipment, the Chief, CI, obtained verbal authorization from the Chief, Agency-Wide Shared Services (AWSS). The CI Division contends that the computer assets were always under its control and secure at all times, and it maintained documentation to verify that its computer assets were being tracked within the Division to their current locations.
Many critical servers were moved to two
different locations on Friday, June 30, 2006.
Fifteen servers used by the W&I Division’s Computer Assisted
were moved by a contractor to the
· One week later, on Friday, July 7, 2006, with 1 freight elevator in the building operational, IRS contract movers were able to more easily transfer 82 pieces of equipment, including 24 additional vital servers, from the Headquarters building to the computer room in the IRS facility in Lanham, Maryland, using required security and inventory controls.
· A review of IRS inventory records for the Headquarters building, as of August 15, 2006, showed that almost one-half of the servers assigned to the Headquarters building had not been scanned or modified after the date of the flooding event. While it is likely that many of these servers remain inside the building, we cannot be sure because the asset tracking system was not in place until 5 calendar days after the flooding.
Because the building was closed, MITS organization employees were unable to perform a physical inventory validation of the workstations and servers remaining in the building. The building reopened for occupancy December 8, 2006, and the IRS plans to begin its annual physical inventory in January 2007. We encourage the completion of this inventory validation because it will provide documented evidence that the computers are still located in the Headquarters building. We had made a similar recommendation during an audit on the IRS’ efforts for Hurricanes Katrina and Rita. Specifically, we recommended the Chief Information Officer establish procedures to conduct a physical inventory validation of all computers at IRS facilities that suffer extensive damage after any major disaster, to identify possible loss or theft of computers. In addition, the report stated this validation should be performed within 30 calendar days after the disaster. Due to the closure of the Headquarters building, we were likewise unable to conduct a physical validation of computer assets located in the building.
Recommendation 1: The Chief, AWSS, should ensure the Incident Management Plans for all IRS locations include the implementation of an asset tracking system and related processes immediately after a disaster.
Management’s Response: The Chief, AWSS, concurred with the finding and recommendation. The IRS developed and implemented an Emergency Incident Asset Retrieval Tracking form, which has been incorporated into the Incident Management Plan Addendum. In addition, all written material concerning incident management planning has been updated to include asset tracking processes, and training was provided to appropriate personnel.
Because the flooding disaster damaged the electrical and ventilation functions of the building, employees were not allowed to work in the building, which required the IRS to locate temporary workspace for all displaced employees. This responsibility was assigned to the AWSS Division. Business Resumption Coordinators for each of the business units provided the Incident Commander with a prioritized list of employees who required space. The AWSS Division secured workstation space arrangements for the displaced employees in 15 different locations in the District of Columbia, Maryland, and Virginia.
In addition to finding workspace for displaced employees, the IRS needed to provide them with computer resources to resume tax administration activities and to move all computer infrastructure operations that existed in the building prior to the flooding. These responsibilities were assigned to the MITS organization. To this end, MITS organization employees worked many hours of overtime that resulted in overtime costs of about $50,000.
Some employees who regained possession of their computers reported to work at other IRS offices and connected directly to the IRS network. For those employees who requested to temporarily work at home, IRS technicians installed secure connectivity software in their computers so these employees could connect to the IRS network.
For displaced employees who reported back to work but did not have computers with which to resume their duties, MITS organization personnel were tasked with locating unassigned computers, visiting the various worksites of displaced employees, and configuring computers to fit each employee’s needs. With more than 2,200 displaced employees, this endeavor was daunting, yet the MITS organization provided all employees with assigned computers by July 28, 2006, a little over 1 month after the flooding occurred.
Additionally, the IRS provided network data and telephone lines in two new locations that were rented for the CI Division and Office of Chief Counsel staffs. Adaptive computer equipment required by some employees with special needs was moved to their temporary work locations.
As previously mentioned, the IRS
moved many servers out of the Headquarters building to new locations. The MITS organization timely restored
connectivity of these servers to the IRS network. For example, MITS organization personnel worked
over the weekend to restore the critical servers removed from the building on
June 30, 2006; the servers were restored by the following Monday, July 3,
2006 (8 calendar days after the flooding).
Most of the vital servers moved on Friday, July 7, 2006, were placed
into operation that weekend (2 weeks after the flooding). In addition, the connectivity of the W&I
Division’s Computer Assisted Publishing System was restored on another
mainframe computer at the
Although the demands created by this disaster required additional equipment and services, the IRS did not request additional funding. We commend the efforts of the IRS and believe the actions taken by the IRS minimized the disruption caused by the flooding disaster.
The overall objective of this review was to evaluate the actions taken by the IRS in response to the flooding of its Headquarters building. Specifically, we determined whether the IRS adequately protected data and computer operations and sufficiently recovered its computer systems and data damaged or disrupted by the flooding. To accomplish our objective, we:
I. Determined whether the IRS protected taxpayer data during and after the flood.
A. Assessed the security of the IRS Headquarters building after the disaster.
B. Assessed the security of taxpayer records and computer equipment during cleanup activities.
II. Determined whether the IRS sufficiently recovered its computer systems and data damaged or disrupted by the flooding.
A. Assessed whether the computer operations and related data were timely and adequately restored.
B. Assessed whether taxpayer records were being adequately protected by employees who were working in facilities outside the control of the IRS.
