A "Security Alliance" refers to a partnership between countries or organizations aimed at enhancing mutual security and defense. These alliances often involve sharing intelligence, resources, and strategies to address common threats, such as terrorism or cyberattacks. Examples include military alliances like NATO and various cybersecurity coalitions. Such alliances can also focus on economic security, promoting stability and cooperation in trade and investment. By working together, members of a security alliance can strengthen their collective defense capabilities and respond more effectively to emerging challenges in a rapidly changing global landscape.
