In fiscal year 2006, the Internal Revenue Service (IRS) collected about $2.5 trillion in tax payments and paid about $277 billion in refunds. Because IRS relies extensively on computerized systems, effective information security controls are essential to ensuring that financial and taxpayer information is adequately protected from inadvertent or deliberate misuse, fraudulent use, improper disclosure, or destruction. As part of its audit of IRS's fiscal years 2006 and 2005 financial statements, GAO assessed (1) IRS's actions to correct previously reported information security weaknesses and (2) whether controls were effective in ensuring the confidentiality, integrity, and availability of financial and sensitive taxpayer information. To do this, GAO examined IRS information security policies and procedures, guidance, security plans, reports, and other documents; tested controls over five critical applications at three IRS sites; and interviewed key security representatives and management officials. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-07-364/html/GAOREPORTS-GAO-07-364.htm https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-07-364/pdf/GAOREPORTS-GAO-07-364.pdf GAO-07-364 https://www.govinfo.gov/app/details/GAOREPORTS-GAO-07-364 Other Written Product GAO-07-364; Information Security: Further Efforts Needed to Address Significant Weaknesses at the Internal Revenue Service; Computer security Confidential information Data integrity Information security Internal controls Physical security Program evaluation Risk assessment Risk management Servers Tax administration systems Tax information confidentiality Program implementation Title 31 Section 720 31 U.S.C. 720 Volume 116 Page 2946 116 Stat. 2946 Public Law 107-347
