The CIA triad is a common model that forms the basis for the development of security systems and strategies. The three letters in CIA triad stand for Confidentiality, Integrity, and Availability. Each aspect of the CIA triad represents the foundational principles of information security and covers every possible way that sensitive data can be compromised. A data breach is any security incident in which unauthorized parties access sensitive or confidential information. The CIA triad can be used to evaluate security procedures and tools and assess what went wrong and what worked after a negative incident. This differentiation helps security teams pinpoint the different ways in which they can address each concern.

What You'll Learn
Confidentiality: Preventing unauthorised access to data
Confidentiality, the first element of the CIA triad, is about keeping sensitive information private and secure. The aim is to prevent unauthorised access to data by cybercriminals or employees without legitimate access. This is roughly equivalent to privacy.
To prevent unauthorised access to data, you can classify and label restricted data, enable access control policies, and use multi-factor authentication (MFA) systems. It is advisable to ensure that all employees have the training and knowledge they need to recognise the dangers and avoid them. This training can include educating employees on strong passwords and password-related best practices, as well as common social engineering methods used by bad actors to manipulate users into breaking data-handling rules. For example, a method for protecting sensitive data and ensuring confidentiality is requiring an account number or routing number when banking online.
Data encryption is another common method of ensuring confidentiality. Encryption is the process of encoding data to prevent unauthorised access. It is a powerful tool that can help secure information and prevent it from falling into the wrong hands. Data stewardship and governance are also important considerations when dealing with large data volumes. Responsible data stewardship, auditing, and oversight are crucial to ensuring confidentiality.
Additionally, it is essential to conduct regular risk assessments to identify vulnerabilities and implement necessary controls to address these risks. This involves analysing operations to measure the risks, threats, and vulnerabilities in systems that could compromise sensitive information. By implementing these controls, you will satisfy one or more of the CIA triad's core principles.
Overall, by implementing these measures and strategies, organisations can effectively prevent unauthorised access to data and protect the confidentiality of sensitive information.

Integrity: Ensuring data is accurate and reliable
Integrity is the second element of the CIA triad, which is a common model that forms the basis for the development of security systems. It refers to the completeness, accuracy, and reliability of data, as well as an organization's ability to protect it from corruption. Data integrity is maintained only if the data is authentic, accurate, and reliable.
To ensure data integrity, it is essential to prevent unauthorized alterations to the data. This involves implementing measures to safeguard against data breaches and unauthorized access. For example, data encryption, access control policies, and multi-factor authentication (MFA) systems can be utilized to protect data from tampering and unauthorized modifications.
Additionally, it is crucial to ensure that the information itself is correct and up-to-date. Organizations should establish rigorous data validation and verification processes to identify and rectify any inaccuracies or inconsistencies within the data. Regular audits and data quality checks can help maintain the integrity of the information.
Moreover, data integrity also encompasses the protection of data during transit. Measures such as cryptographic systems and digital signatures can be employed to ensure that data cannot be altered during transmission. This is essential to prevent data corruption or unauthorized modifications while data is being transferred between systems or users.
By prioritizing data integrity, organizations can maintain the reliability and trustworthiness of their data. This is crucial for effective decision-making, maintaining the organization's reputation, and ensuring compliance with regulatory frameworks such as ISO 27001 and the GDPR, which emphasize the importance of data integrity.

Availability: Ensuring data is accessible when needed
Data availability is a critical aspect of data management and security. It ensures that data is accessible to authorized users when needed. In other words, data availability guarantees reliable access to data.
A scenario in which data is not accessible is highly problematic because it can prevent the delivery of services, and in some cases creates a chain reaction that compromises other data as well. Therefore, organizations must take measures to ensure that mission-critical data remains accessible at all time.
- Data Backups: Regularly back up data to a secure, off-site location. This ensures that even in the event of a physical disaster, your data can be recovered.
- Redundancy: Implement redundant systems, such as RAID (Redundant Array of Independent Disks), to protect against data loss due to hardware failure.
- Data Replication: Replicate data across multiple locations to ensure availability even if one location experiences an outage.
- Data Durability: This is a different but related objective to data availability, with an emphasis on the long term. While data availability focuses on system uptime and operational live data, data durability refers to protecting the data throughout its lifecycle.
- Data Retention: Data retention relates to persistent data and records management policies for analysis or compliance purposes. The data involved is archived for later review or to provide evidence in legal situations, rather than for any immediate or frequent use.
The CIA triad (Confidentiality, Integrity, and Availability) is a common model that forms the basis for the development of security systems. It is a powerful tool in disrupting the Cyber Kill Chain, which refers to the process of targeting and executing a cyberattack. The CIA triad can be used to train employees regarding cybersecurity.

Data classification: Labelling restricted data
Data classification is a process of identifying, categorising, and protecting data according to its sensitivity or impact level. Labelling restricted data is an important aspect of data classification, as it helps organisations manage and protect their data effectively. Restricted data is typically the most sensitive data handled by an organisation, and its unauthorised disclosure could cause severe harm to the organisation or individuals. Examples of restricted data include credit card information, medical records, and personally identifiable information (PII).
To effectively label restricted data, organisations should establish a clear and consistent data classification framework. This framework should include distinct criteria for each classification level, ensuring a uniform approach across the organisation. Microsoft, for instance, recommends using no more than five top-level parent labels, each with five sub-labels, to maintain a manageable user interface. The levels are usually arranged from least to most sensitive, with labels such as "Public", "Internal", "Confidential", and "Highly Confidential".
When labelling restricted data, organisations should consider the following:
- Data Sensitivity: Restricted data is highly sensitive, and access should be limited to authorised individuals only.
- Data Labelling: Decide on the specific labels to be used, such as "Restricted", "Confidential", or "Top Secret", ensuring they clearly indicate the relative sensitivity.
- Access Controls: Determine who has access to different levels of classified data and implement measures such as encryption and multi-factor authentication to protect restricted data.
- Data Handling: Establish procedures for handling restricted data, including guidelines for data storage, retention, and deletion.
- Training and Awareness: Provide training and awareness programmes to ensure employees understand the data classification framework and the importance of proper data handling.
By implementing a comprehensive data classification framework and labelling restricted data appropriately, organisations can improve their data security posture. This helps in complying with regulations, enhancing data management, facilitating risk management, and enabling effective responses to data breaches. Proper data classification ensures that critical information receives the necessary protection, reducing the likelihood of unauthorised access and potential breaches.
