Input: New Strategic Concept will enhance NATO security capabilities: Rasmussen
 Rasmussen highlighted the importance of the reforms to enable NATO to face three main challenges in the future  namely the risk of instability spreading from weak states  the proliferation of ballistic missile technology  and threats to cyber-security.
 Weak states can have a "direct impact" on the alliance's security  Rasmussen told a two-day Young Atlanticist Summit  which opened here on Friday.
 As societies have become reliant on information technology  Rasmussen stressed the need for NATO to develop cyber security systems and to protect important infrastructure such as banking systems  air traffic control or government services.
 There is a "clear" threat from the outside  which requires NATO to develop capabilities to defend Europe against missile attack  said Rasmussen. "Missile defense will bind the NATO allies closer together " he added.
 The Lisbon summit will give NATO the chance to undertake the reforms needed for the 61-year-old organization to tackle these new challenges  said Rasmussen. NATO leaders are expected to agree on a new Strategic Concept to serve as the alliance's guiding document for the next decade.
 This new strategy "will launch an alliance that will be more effective  more engaged  and more efficient " Rasmussen said.
 Rasmussen said NATO and Russia should together create a " security roof for the entire Euro-Atlantic area."
