PII definition and examples
Personally Identifiable Information (PII) is any information that can be used to reasonably infer the identity of an individual, either directly or indirectly. This includes any information that can be used to distinguish or trace an individual's identity, such as their name, social security number, date and place of birth, mother's maiden name, or biometric records. It also includes any other information that can be linked to an individual, such as medical, educational, financial, and employment information.
PII is sensitive information that requires protection to prevent unauthorized access or abuse, which could result in grave repercussions for the individual whose information has been compromised. The unauthorized release of PII can lead to substantial harm, including identity theft or other fraudulent use of the information. As such, it is essential to safeguard PII and ensure that only authorized individuals with a "need to know" have access to such information.
Examples of PII breaches include leaving documents containing PII in open areas, attaching someone's medical information to a letter sent to the wrong recipient, or posting a truncated social security number on a public website. These incidents highlight the importance of maintaining and protecting PII securely and in accordance with applicable laws and policies.
The federal government requires the collection and maintenance of PII to govern efficiently. However, due to the sensitive nature of PII, the government must also take responsibility for safeguarding this information. This includes establishing procedures for the proper handling and storage of PII data and ensuring that only authorized individuals have access to it.
Individuals who have access to PII, such as employees or contractors, also play a crucial role in safeguarding this information. They must adhere to the rules and guidelines set forth by their organizations and governing bodies to protect PII from unauthorized disclosure or misuse. This includes being vigilant about protecting PII, even when working remotely or facing deadlines, as highlighted in the PII Awareness Training Knowledge Check flashcards.

Sensitive vs non-sensitive PII
Personally Identifiable Information (PII) is any information that can be used to identify an individual directly or indirectly. Examples include a name, email address, Social Security Number, or IP address. PII can be further categorized into sensitive and non-sensitive PII.
Non-sensitive PII, also known as personal data, is information that, in isolation, would not cause significant harm to an individual if leaked or stolen. It may or may not be unique to a person and is often publicly available. For instance, a social media handle or a phone number is considered non-sensitive PII as it could identify someone, but it wouldn't be enough to commit identity theft. Other examples include a person's full name or address, which may be listed in a local government's public property records. While non-sensitive PII may not be protected by some data privacy regulations, many companies choose to safeguard it anyway.
On the other hand, sensitive PII (SPII) is information that, if lost, stolen, or disclosed without authorization, could result in significant harm, embarrassment, inconvenience, or unfairness to an individual. It is typically not publicly available, and most data privacy laws require organizations to safeguard it through encryption, access control, and other cybersecurity measures. Examples of SPII include health information, financial records, and government-issued identification numbers.
The distinction between sensitive and non-sensitive PII is crucial for organizations to ensure compliance with data privacy laws, such as the General Data Protection Regulation (GDPR) in the European Union. Under the GDPR, organizations must protect both sensitive and non-sensitive PII. However, special category data, formerly known as sensitive personal data, is given extra protection due to its sensitive nature. This includes data revealing health details, racial or ethnic origin, political opinions, religious or philosophical beliefs, trade union membership, genetic or biometric data, and data concerning a person's sex life or sexual orientation.
It is important to note that whether information is considered sensitive or non-sensitive PII depends heavily on context. For example, a person's phone number may be publicly available and considered non-sensitive, but a database of phone numbers used for two-factor authentication on a social media site would be considered sensitive PII. Additionally, while some pieces of non-sensitive PII may not seem harmful on their own, they can be used by cybercriminals in combination with other information to gain unauthorized access to accounts or commit identity theft. Therefore, organizations must be vigilant in protecting all types of PII and ensuring compliance with relevant data privacy regulations.

Legal and ethical implications of PII breaches
Personally Identifiable Information (PII) is sensitive information that can be used to identify, contact, or locate an individual. It includes data such as an individual's name or social security number. When PII is leaked or exposed without an individual's knowledge or consent, it can have serious legal and ethical implications for the organisation or individual responsible for the breach.
From an ethical standpoint, a PII breach can result in a loss of trust and negative publicity for the organisation, leading to reputational damage. It can also have severe consequences for the individuals whose data has been compromised, including identity theft, financial loss, and a loss of privacy, as their personal data can be used to track and target them for malicious purposes.
Legally, data breaches involving PII are governed by various laws and regulations, such as the General Data Protection Regulation (GDPR) in Europe, the Health Insurance Portability and Accountability Act (HIPAA) in the United States, and the Gramm-Leach-Bliley Act (GLBA). Organisations are required to implement security measures to protect sensitive data and must notify the relevant authorities and affected individuals in a timely manner, typically within 72 hours of becoming aware of the breach. Failure to comply with these regulations can result in significant fines, regulatory penalties, and civil lawsuits from affected individuals. In the United States, violations of data privacy laws can also lead to criminal penalties, including imprisonment.
To mitigate the impact of a PII breach, organisations should follow recommended data breach response guidelines, such as those provided by the Federal Trade Commission (FTC) in the United States. This includes securing their infrastructure, fixing any vulnerabilities, and notifying the appropriate people, such as legal authorities and affected individuals. By taking prompt and appropriate action, organisations can minimise the potential harm caused by the breach and demonstrate their commitment to data protection.
It is important to note that PII breaches can occur due to various factors, including cyberattacks, human error, or improperly configured systems. Regardless of the cause, organisations and individuals must prioritise PII data security and be prepared to respond swiftly and effectively in the event of a breach to minimise the potential harm to all parties involved.
