The US Government Accountability Office (GAO) has called on the federal government to co-ordinate efforts across agencies to ensure uniform policies, standards and strategies on cyber security.
US national cyber security efforts involve several government agencies, local and state government and the private sector. Leadership is also shared by several agencies.
In an earlier report published in March, the GAO said US cybersecurity defences are being hampered by a lack of clear definitions of the roles of the government agencies involved.
The GAO said the US identified the need to define roles and responsibilities as a key challenge to cybersecurity efforts.
The report found that government agencies have overlapping and unco-ordinated responsibilities for cybersecurity and that it is unclear where overall responsibility lies.
In the latest report, the GAO said standardisation is crucial if the US is ever going to present a united front to the world on the issue of cyber security.
Until challenges in leadership, strategy, co-ordination, standards, policies, legal discrepancies and others are overcome, the US will be at a disadvantage in promoting its national interests in the realm of cyberspace, the report said.
The US Congress has been slow to move on passing a comprehensive law to tackle the issue of cyber security, according to US reports.
