(NBC NEWS) -- Intelligence leaders said for the first time on Tuesday that cyber
attacks and cyber espionage have supplanted terrorism as the top
security threat facing the United States.
That stark
assessment, in an annual "worldwide threat" briefing that covered
concerns as diverse as North Korea's belligerence and Syria's civil war,
was reinforced in remarks by the spy chiefs before the Senate
Intelligence Committee.
They expressed concern that computer technology is evolving so quickly it is hard for security experts to keep up.
"In
some cases, the world is applying digital technologies faster than our
ability to understand the security implications and mitigate potential
risks," James Clapper, the director of National Intelligence, told the
committee.
In written testimony, Clapper softened his analysis
somewhat, playing down the likelihood of catastrophic attacks on the
United States in the near term — either through digital technologies, or
from foreign or domestic militants employing traditional violence.
But this year's annual threat briefing underscored how, a decade after
the Iraq war began and nearly two years after the killing of al-Qaida
leader Osama bin Laden, digital assaults on government and computer
networks have supplanted earlier security fears.
On Monday,
White House national security adviser Tom Donilon, citing complaints
from U.S. businesses about alleged Chinese cyber espionage, said the
issue is a growing challenge to economic relations between the United
States and China.
China said on Tuesday it was willing to meet Donilon's request that Beijing talk with the United States about cyber security.
Economic costs
Last
month, a private U.S. computer security company issued a study accusing
a secretive Chinese military unit of being behind hacking attacks on a
wide range of American industries.
China has denied such reports, and says it is a victim of cyber spying by the U.S. government.
The annual economic loss from cyber attacks is estimated to be in the tens of billions of dollars.
In a separate hearing on Tuesday before the Senate Armed Services
committee, Army General Keith Alexander, head of the U.S. military's
Cyber Command, said cyber attacks on private companies and in particular
on the U.S. banking sector were getting worse. He predicted that the
intensity and number of attacks will grow significantly throughout the
year.
FBI
Director Robert Mueller (L), Director of National Intelligence James
Clapper (C) and CIA Director John Brennan testify before a Senate
Intelligence Committee hearing on "Current and Projected National
Security Threats to the United States" on Capitol Hill in Washington
March 12, 2013.
Alexander said the military was
beefing up its cyber warrior team, adding troops from across the
military as well as civilians. He said there would be three teams: a
Cyber National Mission force which will deploy teams to defend against
national-level threats; a Cyber Combat Mission force in charge of
operational control; and a Cyber Protection force which will defend the
military's information systems.
The goal is to add the new
resources to the teams by the end of 2015, but one third of them are
planned to be in place by this September.
Budget cuts
Clapper
also used Tuesday's Intelligence Committee hearing to give an alarming
account of how U.S. intelligence capabilities will be damaged if
Congress does not move to ease financial pressures caused by automatic
across-the-board budget cuts known as sequestration.
Due to
funding cutbacks, thousands of FBI employees could face furloughs, 5,000
intelligence contractors could be terminated, cyber security efforts
could be affected and older overhead intelligence collection systems —
spy satellites — could face cutbacks, he said.
Intelligence
agencies at a minimum want Congress to give them the authority to
redistribute cuts among programs "to minimize the damage," he said.
Clapper presented to the Senate panel a 34-page paper that ran through a
wide variety of threats covered by U.S. intelligence agencies, from
continuing Middle East instability to what is predicted to be China's
continuing domination of the world's supply of rare earth elements.
On two of the most volatile global crisis points, the U.S. spy agencies' assessment was restrained.
While Iran is improving its expertise in technologies including uranium
enrichment and ballistic missiles, which could be used in a nuclear
weapons program, the intelligence community does not believe Iran's
leadership has decided to build a nuclear weapon and does not know if or
when it might do so.
This assessment is consistent with a
controversial 2007 finding, known as a National Intelligence Estimate,
which concluded Tehran had "halted its nuclear weapons program" in fall
2003 and had not restarted it as of mid-2007, although it was keeping
open the option of building nuclear weapons.
Syria's situation
On
Syria, U.S. spy agencies assessed that the erosion of the government of
President Bashar al-Assad's ability to defend itself is accelerating.
Assad's forces have stopped insurgents from seizing cities such as
Aleppo, Damascus and Homs, but the agencies say insurgents have been
gaining strength in rural areas. This could ultimately lead to the
establishment of a "more permanent base" for the rebels in Idlib
province along the border with Turkey.
The listing of
cyber-related attacks as the top item in the annual threat assessment is
a departure from assessments offered previously. In 2011 and 2012, the
first threat listed in the agencies' annual assessment to Congress was
terrorism.
