Science, Technology, and Public Policy

All the world's nuclear-armed states (except for North Korea) have begun modernizing and upgrading their arsenals, leading many observers to predict that the world is entering a new nuclear arms race. While that outcome is not yet inevitable, it is likely, and if it happens, the new nuclear arms race will be different and more dangerous than the one we remember. More nuclear-armed countries in total, and three competing great powers rather than two, will make the competition more complex. Meanwhile, new non-nuclear weapon technologies — such as ballistic missile defense, anti-satellite weapons, and precision-strike missile technology — will make nuclear deterrence relationships that were once somewhat stable less so.

The Kingdom of Saudi Arabia Cyber Readiness at a Glance is the ninth study in a series of country reports assessing national-level preparedness for cyber risks based on the Cyber Readiness Index (CRI) 2.0 methodology. This report provides the most in-depth analysis to date of Saudi Arabia’ current cyber security posture and its efforts to strengthen the country's security and resilience in the wake of significant cyber threats to the nation.

As President Trump increasingly boxes in Tehran, U.S. allies should be worried about the potential for a devastating cyberattack from the Islamic Republic.

In this Project on Managing the Atom Discussion Paper, Philipp C. Bleek chronicles nuclear weapons proliferation choices throughout the nuclear age. Since the late 1930s and early 1940s, some thirty-one countries are known to have at least explored the possibility of establishing a nuclear weapons program. Seventeen of those countries launched weapons programs, and ten acquired deliverable nuclear weapons.

A Senior Iranian Islamic Revolutionary Guard Corps (IRGC) official described a war in cyberspace as "more dangerous than a physical war." This statement was likely made in 2012, in response to a wave of publicly reported cyber operations against Iran, including Stuxnet, Duqu, and Flame. Since these operations, Iran has expanded the role of cyber capabilities in its broader national security strategy. Cyber Security Project Director Michael Sulmeyer assesses the role of cyber tools in Iran's broader strategy.

Nuclear weapons remain the most powerful weapons on the planet and how President Donald Trump’s team manages nuclear issues is critical to our security. These are hard challenges; none were perfectly addressed under President Obama’s leadership. But we made them a priority from day one. Whether or not the new team puts them at the top of the to-do list, here are five issues that will demand their attention before too long.

In March, the Justice Department unsealed an indictment against seven Iranians for hacking the U.S. financial sector and a dam in New York. In doing so, it also clarified what information security officials have argued for years: that the vast majority of hacks exploit known vulnerabilities.
