What are the 3 main pillars of cyber security?

What is the CIA triad?

The CIA triad is a model for information security that consists of three main components: confidentiality, integrity, and availability. These three principles are at the core of information security and are often referred to as the "CIA triad" or the "security triad."

What are the 3 main pillars of cyber security?

Cybersecurity is a complex and multifaceted field, but there are three main pillars that form the foundation of a strong and effective cybersecurity system:

Confidentiality

Confidentiality refers to the ability to keep information private and secure. This means that only authorized individuals should be able to access certain information, and that this information should be protected from being accessed or disclosed to unauthorized parties. This is often achieved through the use of strong authentication methods (such as passwords and two-factor authentication), encryption, and access control measures.

Integrity

Integrity refers to the accuracy and completeness of information. This means that information should not be modified or tampered with without the knowledge and consent of the authorized individuals. To ensure integrity, organizations often use checksums and hash functions to detect any changes to data, as well as backup and recovery systems to ensure that data can be restored in the event of an attack or data loss.

Availability

Availability refers to the ability to access information and systems when needed. This is critical for organizations that rely on technology and data to function, as downtime or disruptions can have serious consequences. To ensure availability, organizations use measures such as redundant systems, load balancing, and disaster recovery plans to minimize the impact of outages or attacks.

There are many other aspects of cybersecurity, and these three pillars are often referred to as the "CIA triad" (confidentiality, integrity, and availability). However, these three pillars form the foundation of a strong and effective cybersecurity system, and they are essential for protecting sensitive information and systems from cyber threats.

Stability, availability and security

Stability, availability, and security (SAS) are three important principles that are often used to guide the design and operation of computer systems, networks, and other technology-based systems.

Stability refers to the ability of a system to perform consistently and reliably over time. A stable system is one that is not prone to crashing or experiencing other types of failures.

Availability refers to the ability of a system to be accessed and used when needed. A system that is highly available is one that is always online and can be accessed by users without interruption.

Security refers to the measures that are taken to protect a system from unauthorized access or attacks. This includes measures such as firewalls, encryption, and secure authentication protocols

In addition to the CIA triad, there are several other key elements of cybersecurity that are important to consider:

Risk assessment

Risk assessment is the process of identifying and evaluating potential threats to an organization's information and systems. This involves analyzing the likelihood and potential impact of different threats, and determining the appropriate measures to mitigate those risks.

Threat intelligence

Threat intelligence is information about current and emerging threats that can help organizations stay ahead of potential attacks. This can include information about specific vulnerabilities, tactics and techniques used by attackers, and indicators of compromise that can help organizations detect and respond to threats in a timely manner.

Security controls

Security controls are measures put in place to protect against cyber threats. These can include technical controls (such as firewalls and intrusion detection systems) as well as administrative controls (such as policies and procedures).

Incident response

Incident response is the process of responding to and managing the aftermath of a cybersecurity incident. This can include steps such as containing the incident to prevent further damage, recovering systems and data, and taking steps to prevent similar incidents from happening in the future.

Compliance

Compliance refers to the need for organizations to adhere to various laws, regulations, and standards related to cybersecurity. This can include industry-specific regulations, as well as broader laws such as the General Data Protection Regulation (GDPR) in the European Union.

Cybersecurity is an ongoing process, and it requires a combination of technology, policies, and processes to be effective. It is important for organizations to regularly review and update their cybersecurity posture to ensure that they are adequately protected against evolving threats.
