AROUND THE AGENCIESStephanie DreyerDefense Department Stephanie Dreyer is director for digital media and strategy for the Department of Defense. (Chet Susslin)

When I meet with Stephanie Dreyer at her office in the D-ring of the Pentagon, she's just back from a trip with Secretary Ash Carter to the Asia-Pacific region—and she has the footage to prove it. She shows me a short, punchy, video of members of the military working and talking about why what they do in the region is important to U.S. security. In March, Dreyer became the Defense Department's first director for digital media and strategy, a job that has her overseeing content on all the department's digital platforms—Facebook, Twitter, Instagram, Vine—as well as coming up with innovative ways to communicate the secretary's agenda. Dreyer, 30, is a native of New Rochelle, New York, and previously served as communications director for the Truman National Security Project, a national security leadership organization in D.C. Her recent projects include helping Carter launch his Facebook page—he's the first secretary of Defense to have one.

AT THE BARHarvey RishikofCrowell & Moring+ Harvey Rishikof is senior cousel for Crowell & Moring. (Chet Susslin)

Harvey Rishikof believes defense and cybersecurity are among the "critical issues that will define our century"—so in March he joined the law firm Crowell & Moring. "People, resources, a commitment to cyber, and the firm culture made it hard to say no," the former dean of faculty at the National War College tells me. As a senior counsel in Crowell & Moring's Privacy & Cybersecurity and Government Contracts groups, he now helps clients "think through tough and interesting legal problems involving cybersecurity" and navigate everything from "entering the government marketplace and bidding on public contracts to complying with complex regulatory regimes." A native of Montreal, Quebec, the 61-year-old Rishikof's areas of expertise include national security, cybersecurity, government contracts, and civil and military courts.

ADVISORY GROUPSJuliette KayyemHomeland Security Advisory Council Juliette Kayyem joins the Homeland Security Advisory Council. (Chet Susselin)

Juliette Kayyem wears many hats: She's on the faculty at Harvard's Kennedy School of Government; she's helping Boston with its 2024 summer Olympics bid in her capacity as founder of security-risk-management firm Juliette Kayyem Solutions; she's a national security analyst for CNN; she hosts a podcast; she's writing a book. And, in May, Kayyem, 45, added another cap to her collection: She was appointed to the Homeland Security Advisory Council to provide Secretary Jeh Johnson with "some perspective and long-term planning." The Los Angeles native is now Boston-based—she was Massachusetts's first undersecretary for homeland security and ran for governor in 2013. (She lost the Democratic primary.) "I think it's helpful for an agency that can sometimes get stuck in the D.C.-ness of it all to still have voices from the outside chiming in," she says. Not that she's unfamiliar with D.C. or the Homeland Security Department: From 2009 to late 2010, she was the department's assistant secretary for intergovernmental affairs.
