What are the principles of the CIA?

The CIA triad is a widely used information security model that can guide an organization's efforts and policies aimed at keeping its data secure. The model has nothing to do with the U.S. Central Intelligence Agency; rather, the initials stand for the three principles on which infosec rests: 1 Confidentiality: Only authorized users and processes should be able to access or modify data 2 Integrity: Data should be maintained in a correct state and nobody should be able to improperly modify it, either accidentally or maliciously 3 Availability: Authorized users should be able to access data whenever they need to do so

What is loss of confidentiality?

A loss of confidentiality is defined as data being seen by someone who shouldn't have seen it. Big data breaches like the Marriott hack are prime, high-profile examples of loss of confidentiality.

What is public key cryptography?

Public-key cryptography is a widespread infrastructure that enforces both As: by authenticating that you are who you say you are via cryptographic keys, you establish your right to participate in the encrypted conversation. Confidentiality can also be enforced by non-technical means.

What is the most important way to enforce confidentiality?

Authorization, which determines who has the right to access which data: Just because a system knows who you are, it doesn't necessarily open all its data for your perusal! One of the most important ways to enforce confidentiality is establishing need-to-know mechanisms for data access; that way, users whose accounts have been hacked or who have gone rogue can't compromise sensitive data. Most operating systems enforce confidentiality in this sense by having many files only accessible by their creators or an admin, for instance.

What are some examples of breaches of integrity?

Breaches of integrity are somewhat less common or obvious than violations of the other two principles, but could include, for instance, altering business data to affect decision-making, or hacking into a financial system to briefly inflate the value of a stock or bank account and then siphoning off the excess.

How can SecurityScorecard help?

The CIA triad alone is not enough to keep your data secure. You also need to be aware of where your risks are.

What are some examples of confidentiality?

For example, examples of Confidentiality can be found in various access control methods, like two-factor authentication, passwordless sign-on, and other access controls, but it’s not just about letting authorized users in, it's also about keeping certain files inaccessible. Encryption helps organizations secure information from both accidental disclosure and malicious attacks.

What is availability in DDoS?

Availability is really about making sure your systems are up and running so that business can continue, even in the face of an attack. DDoS (Distributed Denial of Service) attacks rely on limited availability, for example. For this reason, creating a DDoS response plan and redundancy in your systems is a way of ensuring availability. However, when there’s no attack, systems can still fail and become unavailable, so load balancing and fault tolerance are a way to keep systems from failing.

Why are the three concepts in the triad important?

The reason these three concepts are grouped into a triad is so information security professionals can think of the relationship between them, how they overlap, and how they oppose one another. Looking at the tension between the three legs of the triad can help security professionals determine their infosec priorities and processes.

What is the CIA triad?

The CIA triad is widely accepted as a model in information security. It’s not a singular doctrine and there was no one author. Rather the model appears to have developed over time, with roots as old as modern computing, pulling concepts from various sources. Ben Miller, vice president for Dragos, seems to be one of the few people who has done any digging on the origins of the triad. He wrote a blog post 11 years ago about its roots and was unable to find a single source. Instead, the concepts seem to be pulled from a few different documents: a 1976 paper for the U.S. Air Force, for example, and a paper written in the 1980s about the difference between commercial and military computer systems.

How many components are there in the CIA Triad?

Whatever the source, the CIA triad has three components:

What are the three core components of the CIA triad?

Confidentiality, Integrity, and Availability. These are the three core components of the CIA triad, an information security model meant to guide an organization’s security procedures and policies.

What is confidentiality in business?

Confidentiality Confidentiality is synonymous with privacy. Confidentiality measures prevent data from falling into the hands of people who do not have authorization to access said information . In organizations that store large amounts of information, data may be classified based on how detrimental it would be to the organization in the case of a data breach. This process may help direct development of varying levels of security.Ensuring confidentiality requires that all people who have access to sensitive information understand the risks involved. This is often accomplished in special training sessions and may include a lesson in best practices for password safety and social engineering methods. Not only should these employees know how all of the security measures work, they should be able to identify potential risks and be familiar with the legal ramifications associated with data breaches.Everyday examples of confidentiality measures include bank card pin numbers, routing numbers on checks and email passwords. Two-factor authentication, which means using a combination of confidentiality measures such as a password and finger print identification, is common in the professional world. Other aspects of confidentiality include limiting how many places data is stored and the frequency with which data is transmitted. Air gapped computers, disconnected storage devices and keeping only hard copies of documents are all stronger types of confidentiality measures. Integrity In the IT world, integrity is all about making sure information is accurate and always stays that way. Common measures to protect integrity include file permissions and version controls to prevent accidental changes or deletion. Ensuring integrity also requires protection against non-human-related errors such as server crashes. Most importantly, information must be backed up to allow quick recovery when disasters happen. Availability Ensuring availability requires routine maintenance and upgrading of hardware, software and operating system environments. Maintaining adequate bandwidth to limit bottlenecks and developing a comprehensive disaster recovery plan, which includes consideration of natural disasters like floods and fires, is also necessary to ensure availability. Firewalls and proxy servers are additional tools that fall under the umbrella of protecting information availability. New Considerations for the CIA Triad Big data is presenting new challenges to the CIA model because of the massive amount of information being stored, the many sources from which data originates and the array of formats in which the data is stored. Making duplicate copies of so many documents can get expensive fast, and managing big data requires a lot of staff, which multiplies the risks of security breaches and makes oversight difficult.The Internet of things, which involves the increasing capacity for devices other than computers to connect with the Internet, adds additional challenges: for example, in early 2014, security company Proofpoint uncovered a scheme in which household appliances, including a refrigerator, were being hacked and used to steal data from nearby computers. Any product with a computer chip and the ability to network with other machines is vulnerable, and many appliances, like some smart refrigerators, lack adequate security measures to protect against hackers. All new appliances purchased for use around servers containing sensitive information should be carefully vetted by IT staff.No matter how large or small a business or non-profit is, they all deal with sensitive information to some degree. Since new challenges are emerging faster than ever before, CIA should become part of the standard lexicon in offices across the world.

What does CIA stand for in security?

What is the ultimate safeguard against ransomware?

Again, as with integrity, the ultimate safeguard is immutable storage . This is where copies of the data are made that cannot be modified. This is emerging as a primary defense against Ransomware attacks where the attacker encrypts the data and holds it hostage to extort money. With one client we designed a solution moving the immutable backups to a colocation facility not visible from within their environment. This kind of offsite storage is also a safeguard against any number of DR scenarios.

What is zero trust approach?

The Zero-trust approach with integrity is to integrate the approach across all IT silos. This means implementing least privileged access technologies such as role-based access controls (RBAC) and even attribute-based access control (ABAC), an emerging technology standard that can apply context to the permissions. It also involves coordinating encryption technologies, certificate management and backups that include immutable storage as needed.

What does availability mean in business?

But it literally means that data should be available to users whenever and wherever it’s needed to support the business.

What is the CIA triad?

From a security management standpoint, there is a risk-based methodology called the “CIA Triad”: Confidentiality, Integrity, and Availability (CIA). Confidentiality means that only authorized users and processes should be able to access or modify data. Integrity describes that data should be maintained in a correct state, and nobody should be able to improperly modify it, either accidentally or maliciously. Finally, Availability describes that an authorized user should be able to access data wherever and whenever they need it.

What is 5 9s reliability?

In reliability engineering we discuss 5 9s as the concept of a system being highly available (HA). That number was inherited from the telecommunication service provider industry. The literal definition of this is that the system is 99.999% available. This results in an expectation that there be no more than 5.26 minutes of downtime per year.

Why do HA systems fail?

This often happens through lack of maintenance resulting in preventable failures. Remember that at 5 9s they only get 5.26 minutes downtime per year. Failures in these systems point out that in IT we tend to design to meet minimum requirements within the context of capital or operational budgets. What we fail to think about is how to design for the real world. This involves thinking about designing for operational environments.

What is loss of availability?

Loss of availability is defined as data being unable to access, modify or add data. A public example of a security breach based on availability is a distributed denial of service (DDoS) attack. This type of attack consumes a firms Internet infrastructure making it difficult to do business.

What is the best way to protect your data?

Encryption standards include AES (Advanced Encryption Standard) and DES (Data Encryption Standard). Another way to protect your data is through a VPN tunnel. VPN stands for Virtual Private Network and helps the data to move securely over the network.

What does confidentiality mean in a network?

Confidentiality : Confidentiality means that only the authorized individuals/systems can view sensitive or classified information. The data being sent over the network should not be accessed by unauthorized individuals.

What does "available" mean in network?

This means that the network should be readily available to its users. This applies to systems and to data. To ensure availability, the network administrator should maintain hardware, make regular upgrades, have a plan for fail-over, and prevent bottlenecks in a network. Attacks such as DoS or DDoS may render a network unavailable as the resources of the network get exhausted. The impact may be significant to the companies and users who rely on the network as a business tool. Thus, proper measures should be taken to prevent such attacks.

What are some examples of confidentiality violations?

For example, someone may fail to protect their password—either to a workstation or to log in to a restricted area. Users may share their credentials with someone else, or they may allow someone to see their login while they enter it. In other situations, a user may not properly encrypt a communication, allowing an attacker to intercept their information. Also, a thief may steal hardware, whether an entire computer or a device used in the login process and use it to access confidential information.

What is integrity in business?

Integrity involves making sure your data is trustworthy and free from tampering. The integrity of your data is maintained only if the data is authentic, accurate, and reliable.

What happens to availability when there is a power outage?

If, for example, there is a power outage and there is no disaster recovery system in place to help users regain access to critical systems, availability will be compromised. Also, a natural disaster like a flood or even a severe snowstorm may prevent users from getting to the office, which can interrupt the availability of their workstations and other devices that provide business-critical information or applications. Availability can also be compromised through deliberate acts of sabotage, such as the use of denial-of-service (DoS) attacks or ransomware.

What is MITM in cyber security?

These direct attacks may use techniques such as man-in-the-middle (MITM) attacks, where an attacker positions themselves in the stream of information to intercept data and then either steal or alter it. Some attackers engage in other types of network spying to gain access to credentials. In some cases, the attacker will try to gain more system privileges to obtain the next level of clearance.
