U.S. Senate's Revised Cybersecurity Act Enhances National Security

Lawmakers on Wednesday introduced in the U.S. Senate a revised draft of the Cybersecurity Act, striking out a controversial clause that would have given the president power to shut down the internet.. Originally introduced in April of 2009 by Sen. John (Jay) Rockefeller IV, D-W.Va., and Sen. Olympia Snowe, R-Maine, the bill is designed to address the nation's vulnerability to cybercrime, global espionage and digital attacks. The proposed "Rockefeller-Snowe" legislation has undergone four revisions so far. The newest draft, which takes into account suggestions from cybersecurity experts in government, the private sector and the civil liberties community, includes two new provisions and five revised ones. An earlier version of the bill garnered criticism because it contained a provision that would have allowed the president to declare a cybersecurity emergency and order the shutdown of internet traffic to and from any compromised federal government or critical infrastructure information system. The revised bill would require the president to collaborate with critical infrastructure owners to develop cybersecurity emergency response plans, the bill states. The president's declaration of a cybersecurity emergency would trigger the implementation of these plans. The link for this article located at SC Magazine is no longer available. .

US 19-Year-Old Phreaker Receives 11 Years For Swatting Threats

In the US a 19-year-old phreaker (or phone phreak) has been sentenced to more than eleven years in prison because he placed numerous emergency calls resulting in the dispatch of special police units or SWAT teams (Special Weapons and Tactics). The SWAT teams arrived at the locations from which the calls were placed only to find sleeping families. Such incidents are increasingly common in the US, giving rise to the term swatting.. In his calls to the 911 emergency line, the now convicted culprit sent falsified caller ID numbers and claimed to have hostages in custody. To change the caller ID function, the phreaker is reported to have manipulated several telephone networks, including AT&T, Sprint and Verizon. When a security specialist at Verizon discovered his activities and sought to investigate further, the phone phreak is said to have threatened the employee and made harassing calls to his land line number, while making the caller ID function appear to show friends and co-workers as placing the calls. At that point, the employee contacted the FBI. The link for this article located at H Security is no longer available. .

U.S. Raises Terror Alert to Orange: Operation Liberty Shield

On the brink of an almost certain U.S. attack on Iraq, Homeland Security Secretary Tom Ridge has ordered America's terrorist alert raised to orange and increased security at ports and land borders, airports, critical infrastructures and across the Internet . Known as Operation Liberty Shield, Ridge said the Homeland Security Department is ratcheting up security, increasing public health preparedness and making sure that the federal response can be deployed quickly. It has assigned one emergency response team to the nation's capital in the event of a terrorist attack. "The intelligence community believes that terrorists will attempt multiple attacks against U.S. and coalition targets worldwide in the event of a U.S.-led military campaign against Saddam Hussein," Ridge said in a statement March 17, moments after President Bush gave Saddam Hussein 48 hours to get out of Iraq or face certain attack by the United States.

The Bush administration signed off Friday on the final version of the United States' strategy for protecting the Internet and securing information systems. The policy statement, called the National Strategy to Secure Cyberspace, calls for the government to work with private industry to create an emergency response system to cyberattacks and to reduce the nation's vulnerability to such threats. "Securing cyberspace is an extraordinarily difficult strategic challenge that requires a coordinated and focused effort from our entire society--the federal government, state and local government, the private sector and the American people," President George W. Bush wrote in a letter introducing the document. The strategy document included several modifications of a previous draft released last September. These modifications included a focus on five specific policy initiatives and the allocation of much of the responsibility for securing the country with the newly established Department of Homeland Security.

Barak Advocates Global Intelligence Database For Terrorism Prevention

Intelligence agencies worldwide must create a global database to share information with each other about threats and attacks by terrorist organizations and "rogue despots like Saddam Hussein. . .. Intelligence agencies worldwide must create a global database to share information with each other about threats and attacks by terrorist organizations and "rogue despots like Saddam Hussein ," former Israeli Prime Minister Ehud Barak said here Monday at the opening general session of the BioSecurity Summit, which is running concurrently with the Comdex trade show. Some steps have been taken to create such a database, but it is not complete, Barak said during his sobering address aimed at health-care professionals, emergency crews and government agency representatives attending the summit. Intelligence agencies naturally want to protect their own databases and make certain that when they share information their databases remain protected, he said. However, cooperation is vitally important in a world where terrorists are active and able to exploit weaknesses in security, at times using technology for ill gain, Barak said, touching on chemical, biological and nuclear threats. The global shipping industry is particularly vulnerable, he emphasized numerous times during a speech in which he often said that he couldn't say much more because of the sensitive nature of the information he possesses about threats and how the Israeli government in particular responds to those. What he would say is that terrorists could use containers on ships to launch coordinated attacks with GPS (Global Positioning System) technology and digital radios to, for instance, release biological or chemical agents into the air. "It's frightening to think how easy launching an attack might be, not necessarily through the air, but through shipping in containers," Barak said, adding that he has some discomfort saying that publicly, but the possibility of "major, simultaneous attacks of a biological nature by terrorist groups," is real. Beyond that,he said, it's important for world leaders to help prepare the people of their nations psychologically for such terrorist acts. Civilian preparation is key, he said. In Israel, for instance, "we practically equipped the whole population" with protection like gas masks against the threat of chemical warfare, especially for children and people who are not mobile, Barak said. His nation also has accumulated a "sizable" amount of antibiotics to fight anthrax and is vaccinating "first responders" such as emergency crews against smallpox. Israel has found "the need to try to predict what should be done not just as far as the need for vaccines, but with training and education of staff and first responders," as well as the public, he said. More money is needed to effectively provide federal security in the U.S. and in other countries, he said, noting that creation of the U.S. Department of Homeland Security will help in that regard. Otherwise, Barak also advocated at least one armed air marshal on airplanes, secure cockpit doors and the right of pilots to decide how threatening passengers should be dealt with, including the possibility of shooting them. "It's just the beginning," he said of the battle against terrorism. "We should approach terrorism as our forefathers approached piracy on the high seas" so that countries agree there will be no assistance of any kind to nations that support terrorism. When that agreement is violated, he said, the nation that is responsible for the breach should be ostracized. It took 20 years to make the seas safer from pirates, Barak said, and it will also take time to fight terrorist organizations. During his speech, Barak referred several times to Iraqi President Saddam Hussein and during a question-and-answer session at the end of his talk, he said he supports the approach of U.S. President George W. Bush, who has pledged a military campaign if Hussein does not voluntarily comply with U.N. weapons inspections and disarm his nation. Hussein and terrorists must be dealt withdecisively, Barak said, adding that in his opinion Bush is acting with "moral and strategic clarity" and the international debate about the wisdom of military action against Iraq will not dilute that clarity. A military campaign against Hussein will be "decisively won," Barak said, and will further send an important message to Iran that the U.S. is willing twice in 12 years to wage war. In the only moment of levity during his remarks, Barak was asked his views about particle filtering systems for airplanes, schools and other enclosed spaces known to have poor air quality and which therefore could be particularly vulnerable to a biological or chemical attack. Barak gestured and said "or gambling palaces," referring to the myriad Las Vegas casinos with their pumped-in air that is often already filled with cigarette smoke. Such efforts may be too focused on air travel than is necessary, to the detriment of particle filtering in other areas. He stressed that in general, officials are "far behind" the ability to sense the presence of biological agents in real time. Unlike the security checks, including metal detectors, before the Bill Gates opening keynote speech Sunday night at the MGM Grand hotel, there was no discernible security presence for the Barak talk save for one dark-suited man who stood, hands clasped in front of him, to the side as the former Israeli prime minister spoke and who then followed closely behind as Barak exited the stage.

They may not be the Continental Congress, but hundreds of IT experts from the defense and intelligence communities gathered here yesterday to share ideas and plans on emergency responses to a terrorist attack on the nation. Only blocks from the spot where the Founding Fathers signed the Declaration of Independence, more than 900 government and private-sector officials met to discuss efforts to improve collaboration and information sharing among the hundreds of federal, state and local agencies in charge of emergency response in the event of future terrorist attacks. On the first day of the three-day Information Sharing and Homeland Security conference, officials have been clear on what the overall strategy is for detecting and preventing future attacks: Create a nationwide information-sharing architecture by leveraging the billions of dollars in federal IT investments, rather than building something from scratch.
