Encryption: Encrypting PII data during transit & at rest protects it against illegal access or interception. Encryption turns data into unreadable ciphertext that can only be decrypted using the correct cryptographic keys.

Access controls: Strong access controls ensure that only authorized individuals have access to personally identifiable information [PII]. This comprises role-based access controls [RBAC], least privilege principles & multi-factor authentication [MFA] techniques that authenticate users’ identities prior to providing access.

Data minimization: Data minimization entails gathering & maintaining only the least amount of personally identifiable information [PII] required for commercial reasons. By reducing the amount of PII data maintained organizations can lower their risk of exposure in the case of a data breach.

Secure storage solutions: Encrypted databases, secure file servers & cloud storage systems with strong security features can help protect PII data from unauthorized access or tampering. Organizations should select storage systems that meet industry standards & legal requirements for data protection.

PII Protection Regulations & Laws

Major data protection rules, such as the European Union’s [EU] General Data Protection Regulation [GDPR] & California’s Consumer Privacy Act [CCPA], have had a substantial impact on how corporations handle & protect Personally Identifiable Information [PII]. GDPR, which went into effect in May 2018, intends to increase data protection & privacy rights for individuals in the EU & the European Economic Area. It applies to all companies that process personal data of individuals residing in the EU, regardless of their location. Similarly, the CCPA, which went into effect in January 2020, gives California residents certain rights over their personal information while also requiring firms that collect, sell or reveal their data to follow specific guidelines.

Organizations must follow specific GDPR & CCPA regulations for processing & securing PII data. These include obtaining explicit consent from individuals before collecting their personal information, providing transparent privacy notices outlining the purposes & legal basis for data processing, implementing appropriate security measures to protect PII data from unauthorized access or disclosure & allowing individuals to exercise their rights regarding their personal information, such as the right to access, correct, delete or restrict the processing of data.

Organizations subject to GDPR must appoint a Data Protection Officer [DPO] who is in charge of ensuring GDPR compliance, performing data protection impact assessments [DPIAs] & acting as a point of contact for individuals & regulatory authorities. Furthermore, GDPR imposes stringent requirements for cross-border data transfers, requiring organizations to use appropriate safeguards, such as Standard Contractual Clauses [SCCs] or Binding Corporate Rules [BCRs], when transferring PII data from the EU/EEA to countries with insufficient data protection laws.

Noncompliance with GDPR & CCPA can lead to serious implications for businesses, such as regulatory fines, legal liability & reputational harm. GDPR authorizes regulatory authorities to levy fines of up to twenty (€20) Million Euros or four percent (4%) of the organization’s global annual revenue, whichever is greater, for significant violations of its rules. Similarly, the CCPA allows for statutory damages of up to $7,500 USD per infraction in certain circumstances, as well as civil fines imposed by the California Attorney General.

Risks & Threats to PII

Common cyber threats targeting PII

Phishing: Phishing emails, texts or websites spoof legitimate companies in order to fool people into providing personally identifiable information [PII], such as login passwords, credit card details or social security numbers. Phishing attacks frequently employ social engineering techniques to instill a sense of urgency or anxiety in victims, causing them to behave impulsively.

Malware: Malicious software, such as ransomware, spyware or keyloggers, can infect devices & compromise the personally identifiable information stored on them. Ransomware encrypts files or locks devices & demands payment for their decryption, whereas spyware quietly watches & collects sensitive data such as keystrokes, passwords & browsing histories.

Data breaches: Data breaches occur when thieves obtain illegal access to systems, databases or networks that hold personally identifiable information [PII]. These breaches disclose a vast amount of sensitive information, such as names, addresses, phone numbers & financial information, which can be used for identity theft, financial fraud or other nefarious purposes.

Best Practices for PII Protection

  1. Implementing strong access controls & authentication mechanisms

Implementing strong access controls & authentication systems is a critical step in protecting Personally Identifiable Information. This entails limiting access to personal data to authorized personnel with a legitimate need to access it for employment functions or responsibilities. Organizations should follow the concept of least privilege, which ensures that people only have access to the Personally Identifiable Information required for their respective activities. Furthermore, adding Multi-Factor Authentication [MFA] offers an extra degree of protection by forcing users to give several forms of verification, such as a password & a one-time code texted to their mobile device, prior to accessing personally identifiable information.

  1. Encrypting PII data in transit & at rest

Encrypting Personally Identifiable Information data both in transit & at rest is critical for preventing unauthorized access or interception. Personal data is encrypted into an unreadable format known as ciphertext using cryptographic methods & keys. This assures that even if data is intercepted or read by unauthorized persons, it is rendered incoherent & unusable without the decryption key. To protect personally identifiable information from eavesdropping, tampering or theft organizations should employ strong encryption methods such as Transport Layer Security [TLS] for data in transit & Advanced Encryption Standard [AES] for data at rest.

  1. Regularly updating security measures & software

Regularly updating security procedures & software is critical to ensuring the integrity & efficacy of Personally Identifiable Information protection measures. This involves quick installation of security patches, updates & fixes to address known vulnerabilities & reduce the chance of cybercriminals exploiting them. Organizations should have a comprehensive patch management approach to guarantee that security patches are applied promptly across all systems, applications & devices that hold or handle PII. Regular security assessments, vulnerability scans & penetration testing also assist discover & address potential security flaws before they are exploited by bad actors.
