CISA (Network Security and Infrastructure Security Bureau) leads the national efforts to understand, manage and reduce the risks of our network and physical infrastructure. CISA connects stakeholders in industry and government, and uses resources, analysis and tools to help them build their own network, communication and physical security and resilience, thus helping to ensure that the American people have a secure and resilient infrastructure.
NIST = National Institute of Standards and Technology was established in 190 1 and is now a part of the US Department of Commerce. NIST develops network security standards, guidelines, best practices and other resources to meet the needs of American industry, federal agencies and the general public. Our activities range from generating specific information that organizations can put into practice immediately to long-term research to predict technological progress and future challenges.
Some NIST network security tasks are defined by federal regulations, administrative orders and policies. For example, the Office of Management and Budget (OMB) requires all federal agencies to implement NIST network security standards and guidelines for non-national security systems. Our cyber security activities are also driven by American industry and public demand. NIST actively works with stakeholders to determine priorities and ensure that our resources can solve the key problems they face.
NIST has also improved the understanding and management of privacy risks, some of which are directly related to network security.
The priority areas that NIST has contributed to and plans to pay more attention to include encryption, education and labor, emerging technologies, risk management, identity and access management, measurement, privacy, trusted networks and trusted platforms.
The Diplomatic Security Bureau (DSS = Diplomatic Security Bureau) is the federal law enforcement and security bureau in the State Council, USA. The mission of the Diplomatic Security Bureau is to ensure diplomatic security and protect the integrity of American travel documents. IT has the largest global influence among federal law enforcement agencies in the United States, with offices in 29 cities in the United States and more than 270 locations around the world, and protects the State Council's information and information technology (IT) assets in more than 270 locations around the world. This includes protecting the global network infrastructure consisting of networks and mobile devices.
Since the establishment of 1986, DSS has continuously expanded its network security capabilities, and established the Network and Technical Security Bureau in May 20 17. The bureau uses advanced technology and operational security expertise to better identify and respond to network risks and threats, including security challenges from hackers, rogue operators, nation-states and internal threats.
The core responsibilities of DSS network security include:
The National Security Agency/Central Security Agency (NSA/CSS) leads the US government in the field of cryptography, including SIGINT insight and network security products and services, and makes the operation of computer networks gain decisive advantages for the country and our allies. Throughout the website, NSA/CSS will be collectively referred to as NSA.
The Central Security Bureau provides timely and accurate password support, knowledge and help for the military cryptology community, and promotes the partnership between the National Security Bureau and the armed forces cryptology department.
