The two leaders had a private dinner at the White House after Cameron arrived here yesterday.
Substantive discussions are scheduled to take place today after which the two leaders would address a joint press conference.
"The United States has a special relationship with the United Kingdom and the President is looking forward to welcoming the Prime Minister to the White House on Thursday evening," White House Press Secretary, Josh Earnest told reporters yesterday.
"I'm confident that the close counter-terrorism partnership that we have with the United Kingdom will be discussed. They will discuss the ongoing campaign against ISIL," he said.
"The British military has made significant commitments to that effort. We're deeply appreciative of them. I'm confident that the two leaders will have an opportunity to discuss that," he said, adding, they will also be discussing economic issues as well.
"We certainly anticipate that the two leaders will be discussing cyber-security during the visit. The United States works very closely with the British on a whole range of counter-terrorism measures, including cyber threat and cyber-security policies," Earnest told reporters.
"I think that our British counterparts would agree that it is imperative that we properly balance the need for government intelligence agencies and national security agencies to have access to certain kinds of information to try to protect their citizens. At the same time, it is critically important for the government to protect the privacy of their citizens.
Ahead of their meeting, Obama and Cameron in a joint op-ed pledged to work together against terrorists.
"We will continue to stand together against those who threaten our values and our way of life. When the freedoms that we treasure came under a brutal attack in Paris, the world responded with one voice. Along with our French allies, we have made clear to those who think they can muzzle freedom of speech and expression with violence that our voices will only grow louder," the op-ed said.
