Congress almost certainly won’t pass any kind of major cybersecurity legislation in 2013, according to industry officials, lobbyists and others who track the issue.

Protecting the nation’s cyber infrastructure has been a top priority for the White House and many lawmakers, but the legislative effort has been done in by fugitive intelligence contractor Edward Snowden’s leaks, a crowded congressional agenda, differing views over the role of the Department of Homeland Security and affiliated organizations, and a wait-and-see approach to an executive branch cybersecurity initiative that won’t be wrapped up until next year.

Lawmakers are still likely to keep discussing cybersecurity, and the legislative push could get revived in 2014. The U.S. Chamber of Commerce is holding its second annual cybersecurity summit Wednesday, and another summit is happening the same day at the National Press Club.

Leaders of the Senate Homeland Security and Governmental Affairs Committee are working together to come up with bipartisan legislation. A House Homeland Security subcommittee last week approved a smaller cybersecurity bill (HR 3107) that would seek to strengthen the government’s cybersecurity workforce, and the committee as a whole is working to write broader legislation.

But that broader House Homeland Security draft bill is an example of some of the hurdles in the way of enacting a cybersecurity measure this year.
