context_page_description: A security increase often occurs when a nation, state, or institution has recently suffered from a serious incident or is under the perception that there is an increased risk for an incident to occur that endangers or potentially endangers its well-being.
  Historically, security has been increased by governments and private institutions for a variety or reasons, including incidents that have occurred to themselves, to other similar institutions, or to the world, nation, or region following a high-profile event or a perceived threat of one. When this occurs, many identify the move as elevated, heightened, or "beefed-up" security.
  Those who are forced to make changes or be extra-vigilant as a result or the increase sometimes refer to the new era as the "security age."
  Institutions which often increase security in response to perceived risks include airports, government buildings, international borders, hospital, schools, religious institutions, and tourist attractions. The September 11 attacks on the World Trade Center in 2001 resulted in security being greatly increased around the world.
  Common methods employed to increase security include:
context_section_description: After the Boston Marathon bombing, police vowed to install additional security measures—including bag checks and additional barriers—while maintaining a friendly, happy atmosphere. Police banned backpacks, strollers, suitcases, glass containers, some costumes and props, weight vests, and items larger than 5 by 5 inches (13 cm × 13 cm). More than 3,500 uniformed Boston Police officers were present for security.
