Critical infrastructure and key resources (CIKR)

Critical infrastructure and key resources (CIKR) are those physical and cyber systems and assets that are so vital to the United States that their incapacitation or destruction would have a debilitating impact on national security, economic security, public health and safety, or any combination thereof.

CIKR includes, but is not limited to, the following 16 sectors:

-Information and telecommunications
-Transportation
-Energy
-Banking and finance
-Water
-Emergency services
-Government
-Food and agriculture
-Chemical
-Nuclear
-Defense
-Space

Critical infrastructure and key resources are those systems and assets whose loss or damage would have a debilitating impact on the security of the United States. The term encompasses both physical and cyber systems and assets.

CIKR includes, but is not limited to, the 16 sectors identified by the Department of Homeland Security:

-Information and telecommunications
-Transportation
-Energy
-Banking and finance
-Water
-Emergency services
-Government
-Food and agriculture
-Chemical
-Nuclear
-Defense
-Space

What are the 5 key critical infrastructure sectors?

The five key critical infrastructure sectors are:

1. Transportation
2. Energy
3. Water
4. Communications
5. Financial Services

What are the four key critical infrastructures?

There are four key critical infrastructures:

1. Financial services: This infrastructure includes banks, stock exchanges, and other financial institutions.

2. Energy: This infrastructure includes power plants, electric grids, and natural gas pipelines.

3. Communications: This infrastructure includes telephone networks, the Internet, and broadcast media.

4. Transportation: This infrastructure includes airports, seaports, and railroads.

What are the 10 critical infrastructure sectors?

1. Energy
2. Banking and finance
3. transportation
4. water
5. public health
6. emergency services
7. government
8. communications
9. information technology
10. food and agriculture

What is considered Cikr?

In computer security, CIKR (pronounced like "sicker") is an acronym for Critical Infrastructure and Key Resources. CIKR includes physical and cyber systems essential to the minimum operations of society. They are categorized into 16 sectors, which are further divided into subsectors.

The 16 sectors are:

1. Agriculture and food
2. Banking and finance
3. Chemical
4. Commercial facilities
5. Communications
6. Critical manufacturing
7. Dams
8. Defense industrial base
9. Emergency services
10. Energy
11. Government facilities
12. Healthcare and public health
13. Information technology
14. Nuclear reactors, materials, and waste
15. Transportation systems
16. Water and wastewater systems

CIKR have many dependencies, which can be physical, logical, or human. For example, the electric power grid is a physical infrastructure that is dependent on the financial sector for funding, and on the human resources sector for workers.

CIKR are also often interconnected, so that a disruption to one sector can have ripple effects on others. For example, an attack on the transportation sector could affect the supply chain for the chemical sector, or an attack on the healthcare sector could overload the emergency services sector.

The goal of CIKR protection is to reduce the vulnerabilities and consequences of attacks on CIKR. This can be done through physical security measures, such as fortifying buildings, or through cyber security

Who is responsible for Cikr?

The short answer is that the network administrator is responsible for Cikr. However, there are a few things to keep in mind.

First, Cikr is a security protocol, and as such, it is the responsibility of the network administrator to ensure that it is properly configured and implemented. Second, Cikr is designed to protect against a specific type of attack, known as a man-in-the-middle attack.

In a man-in-the-middle attack, an attacker intercepts communication between two parties and impersonates one of the parties in order to gain access to sensitive information. Cikr is designed to prevent this type of attack by verifying the identity of both parties before allowing communication to take place.

Third, Cikr is not a silver bullet. It is important to remember that no security protocol is 100% effective. Cikr can help to protect against man-in-the-middle attacks, but it cannot prevent all types of attacks.

Fourth, Cikr is not a substitute for good security practices. Even with Cikr in place, it is important to follow good security practices, such as using strong passwords and keeping software up to date.

Ultimately, the responsibility for Cikr lies with the network administrator. However, all users of the network should be aware of the importance of security and should take steps to protect themselves.
