Admin NatSec spokes describes doc as 'update to similar directive dating back to 2004'...

Man, Glenn Greenwald at the UK Guardian has got a very good, and very high-level, source (or sources).

After his Wednesday blockbuster release of secret court documents detailing an order to release millions of Verizon phone records to the NSA, and his arguably more disturbing Thursday blockbuster release of classified documents detailing the secret PRISM program allowing the government "direct access" to the servers of giant Internet service providers like Microsoft, Yahoo!, YouTube, Google and Skype, he has, as promised earlier today, just released another major classified document.

This one is a classified 18-page Presidential Policy Directive issued by President Obama last October detailing "Offensive Cyber Effects Operations (OCEO)" which "can offer unique and unconventional capabilities to advance US national objectives around the world with little or no warning to the adversary or target and with potential effects ranging from subtle to severely damaging".

It is said, by an Administration national security spokesperson, to be an update to "a similar directive dating back to 2004."

Here are the key details from Greenwald's latest blockbuster report, written along with the Guardian's Ewen MacAskill...

Barack Obama has ordered his senior national security and intelligence officials to draw up a list of potential overseas targets for US cyber-attacks, a top secret presidential directive obtained by the Guardian reveals.

The 18-page Presidential Policy Directive 20, issued in October last year but never published, states that what it calls Offensive Cyber Effects Operations (OCEO) "can offer unique and unconventional capabilities to advance US national objectives around the world with little or no warning to the adversary or target and with potential effects ranging from subtle to severely damaging".

It says the government will "identify potential targets of national importance where OCEO can offer a favorable balance of effectiveness and risk as compared with other instruments of national power".

The directive also contemplates the possible use of cyber actions inside the US, though it specifies that no such domestic operations can be conducted without the prior order of the president, except in cases of emergency.

The aim of the document was "to put in place tools and a framework to enable government to make decisions" on cyber actions, a senior administration official told the Guardian.
...
The directive's publication comes as the president plans to confront his Chinese counterpart Xi Jinping at a summit in California on Friday over alleged Chinese attacks on western targets.

Even before the publication of the directive, Beijing had hit back against US criticism, with a senior official claiming to have "mountains of data" on American cyber-attacks he claimed were every bit as serious as those China was accused of having carried out against the US.
...
The document says that agencies should consider the consequences of any cyber-action. They include the impact on intelligence-gathering; the risk of retaliation; the impact on the stability and security of the internet itself; the balance of political risks versus gains; and the establishment of unwelcome norms of international behaviour.
...
The revelation that the US is preparing a specific target list for offensive cyber-action is likely to reignite previously raised concerns of security researchers and academics, several of whom have warned that large-scale cyber operations could easily escalate into full-scale military conflict.
...
The full classified directive repeatedly emphasizes that all cyber-operations must be conducted in accordance with US law and only as a complement to diplomatic and military options. But it also makes clear how both offensive and defensive cyber operations are central to US strategy.
...
The directive provides that any cyber-operations "intended or likely to produce cyber effects within the United States" require the approval of the president, except in the case of an "emergency cyber action". When such an emergency arises, several departments, including the department of defense, are authorized to conduct such domestic operations without presidential approval.
...
Earlier this year, the Pentagon publicly accused China for the first time of being behind attacks on the US. The Washington Post reported last month that Chinese hackers had gained access to the Pentagon's most advanced military programs.

The director of national intelligence, James Clapper, identified cyber threats in general as the top national security threat.

Obama officials have repeatedly cited the threat of cyber-attacks to advocate new legislation that would vest the US government with greater powers to monitor and control the internet as a means of guarding against such threats.
...
In a statement, Caitlin Hayden, national security council spokeswoman, said: "We have not seen the document the Guardian has obtained, as they did not share it with us. However, as we have already publicly acknowledged, last year the president signed a classified presidential directive relating to cyber operations, updating a similar directive dating back to 2004. ... The procedures outlined in this directive are consistent with the US Constitution, including the president's role as commander in chief, and other applicable law and policies."
