A commercial homeland security test facility is serving as a proving ground for systems and processes for all levels of government responders. It features hardware and software from dozens of companies as well as potential crisis scenarios developed by government officials.

Successfully managing homeland security activities requires government agencies to balance their efforts between different issues such as cyberspace, border protection, law enforcement and international cooperation. Good communications between all facets of federal, state and local government as well as the private sector is key to maintaining this equilibrium. But achieving ideal levels of coordination remains a challenge as officials struggle to counter external threats while attempting to restructure internal communications across organizational boundaries.

To protect information systems from security breeches, organizations increasingly are embracing a comprehensive strategy that relies on both technology and enforced policies. Meanwhile, the legal system has been hard pressed to keep pace with information system protection issues, leaving many questions unanswered about how far businesses may go to protect their systems.

The U.S. Coast Guard plays a vital role helping tie together pieces of the national security community. The Coast Guard is unique in that, while it is a military service, organizationally it sits within the U.S. Department of Homeland Security and clearly has homeland security/counterterrorism, public safety and law enforcement roles. This positioning within several national security communities allows the Coast Guard to provide an invaluable coordination and linking function.

In the 18 months following the terrorist attacks, the U.S. government has undergone a series of structural changes. At the state and federal levels, efforts are underway to enhance communications and information-sharing infrastructures among agencies and other organizations. Public institutions also have reached out to the private sector to form partnerships designed to protect vital national infrastructures.

The major consolidation of federal agencies that is creating the new Department of Homeland Security also is impelling private industry to adapt to the changing landscape. The resulting environment places more responsibility on businesses to protect vital infrastructure, but it also clears the way to a closer and more productive relationship between the commercial and public sectors.

The commander of national cybersecurity has issued a call to arms to both private-sector and government organizations in the battle against cunning adversaries bent on wreaking havoc on U.S. critical infrastructures. During the past year, many sector-specific government agencies, including the U.S. Department of Homeland Security, have been working hand-in-glove with their industry counterparts to draft specific battle plans. Among the top priorities in the telecommunications and information technology sectors is conducting a national vulnerability assessment of all infrastructure. Similar plans also were designed for the other 15 component sectors covered by the department's National Infrastructure Protection Plan.

Sky marshals, metal detectors and multiple identification checks may increase security in the corporeal world, but guarding the nation's information superhighway requires different tactics. And in the information age, homeland security must extend into the digital realm, or even a tiny crack could allow adversaries into some of the most important systems in the world today.

No, the title is not a redundancy. Given all the recent events in homeland security, it appears the whole process will undergo yet another round of reviews. I don’t think any of us would question that security is better today than in 2001. But is it good enough? Probably not.
