3.3 Compare and contrast concepts and strategies to protect data Safeguarding sensitive information is crucial in today's data-driven world. This presentation will explore various data types, classification schemes, and methods to effectively secure and protect critical business assets. Data Types and Their Characteristics Regulated data: Highly sensitive information subject to strict compliance and privacy rules. Trade secrets: Confidential business information that confers a competitive advantage. Intellectual property: Legally protected creative works, designs, and inventions. Legal information: Sensitive data related to lawsuits, contracts, and other legal matters. Financial information: Proprietary records of a company's income, expenses, and assets. Human- and non-human-readable data: Information in both machine-interpretable and human- readable formats. Regulated Data Regulated data refers to highly sensitive information that is subject to strict compliance and privacy rules. This includes personal data, financial records, and other confidential information protected by laws and regulations such as HIPAA, GDPR, and PCI-DSS. Proper handling and storage of regulated data is critical to avoid legal penalties and reputational damage. Trade Secret Data Trade secrets are highly confidential business information that provide a company with a competitive advantage.

Public Data Restricted Data Information that can be freely shared with Sensitive information that has additional anyone, such as marketing materials, press access controls and handling requirements, releases, and published reports. like classified government documents or customer credit card numbers. Sensitive Data Highly Confidential Strict Access Compliance Sensitive data includes the Controls Regulations most confidential and Sensitive data requires the The handling of sensitive protected information that highest levels of access data is heavily regulated by could cause significant harm control, encryption, and laws and standards such as if disclosed, such as security measures to prevent HIPAA, GDPR, and PCI-DSS personal identities, financial unauthorized access or to ensure the confidentiality, records, and trade secrets. leaks that could integrity, and availability of compromise individual critical information. privacy or a company's competitive advantage. Confidential Data Restricted Access Secure Storage Compliance Confidential data is accessible Confidential data must be stored Requirements only to authorized personnel in secure, encrypted repositories Handling of confidential data is within an organization. Strict with limited visibility. Physical subject to regulatory guidelines access controls and and digital safeguards prevent such as HIPAA, PCI-DSS, and authentication measures unauthorized access or data GLBA. Failure to adhere to these safeguard this sensitive leaks. standards can result in severe information. penalties. Public Data Definition Public data is information that is openly available and accessible to anyone without restrictions or authentication requirements. Examples Common examples of public data include government publications, press releases, public company filings, and publicly available research studies. Accessibility Public data can be freely accessed, shared, and distributed without the need for special permissions or access controls. Regulatory While public data is generally less regulated, organizations must still Considerations ensure compliance with applicable laws and regulations around data privacy, information security, and intellectual property. Restricted Data Heightened Access Control 1 Restricted data requires stringent access controls, including multi-factor authentication, role-based permissions, and strict authorization processes. Secure Storage 2 This highly sensitive information must be stored in encrypted repositories with limited visibility and robust physical and digital security measures. Regulatory Compliance 3 Handling of restricted data is subject to rigorous compliance standards, such as HIPAA, PCI-DSS, and ITAR, to prevent unauthorized access or misuse. Private Data 1 Highly Restricted Private data is the most sensitive and closely guarded information, accessible only to a select few with the highest levels of authorization and access. 2 Strong Encryption This data requires robust encryption techniques, like advanced end-to-end encryption and multi-factor authentication, to protect it from unauthorized access or leaks. 3 Strict Policies Comprehensive data governance policies, audits, and access controls ensure the confidentiality, integrity, and availability of private information at all times. Critical Data Methods to Critical data encompasses the most sensitive and essential information an organization possesses, Secure Data such as financial records, intellectual property, and Protecting sensitive data requires a mission-critical operational data. The loss, multilayered approach using a variety of corruption, or unauthorized access to this data security methods. Geographic restrictions, could have catastrophic consequences, making encryption, hashing, masking, and tokenization robust security measures and strict data work together to safeguard data from governance a top priority. unauthorized access, tampering, and leaks. Geographic Restrictions Limiting data access and storage based on geographic location is a key method for securing sensitive information. This can involve restricting data to specific countries, regions, or even distances from a central office. Geographic restrictions help mitigate risks from nation-state actors, legal jurisdictions, and physical security threats. They also support data sovereignty requirements and reduce the attack surface for potential breaches. Encryption Encryption is a fundamental data security technique that converts information into a coded format, ensuring only authorized parties can access the data. It provides a robust layer of protection against unauthorized access, interception, or tampering. Encryption algorithms, such as AES, RSA, and ECC, leverage complex mathematical functions to scramble data, making it unintelligible to anyone without the correct decryption key or password. Hashing Secure Data Collision Resistance Password Protection Transformation Strong hash algorithms, such as Hashing is commonly used to Hashing is a cryptographic SHA-256 and MD5, are designed securely store passwords by technique that converts data to be collision-resistant, converting them into unique, into a unique, fixed-length digital meaning it is computationally non-reversible hash values. This fingerprint, or "hash value." This infeasible for two different protects against unauthorized process is a one-way inputs to produce the same access, even if the password transformation that cannot be hash value. This property is database is compromised, as reversed, providing a secure crucial for data authentication the original passwords cannot method for data integrity and non-repudiation. be recovered. verification. Masking 1 Data Obfuscation Masking is a data obfuscation technique that replaces sensitive information with fictitious, but realistic-looking, data. This helps protect the original data while still allowing for necessary processing and analysis. 2 Preserving Format Unlike encryption, masking maintains the original data format, enabling applications and systems to continue functioning without disruption. This makes masking well-suited for production environments and real-time data processing. 3 Reversible Process Masked data can be unmasked by authorized personnel with the appropriate credentials, allowing them to access the original sensitive information when needed. This provides controlled access while maintaining data privacy. Tokenization Reversible Masking Reduced Attack Surface Tokenization is a data protection technique that By substituting tokens in place of sensitive data, replaces sensitive information with a non- the attack surface is significantly reduced. sensitive placeholder, or "token." This allows the Tokens do not contain any meaningful original data to be recovered when needed, information, making them less valuable to making it a reversible process unlike hashing. attackers. Preserving Format Compliance Benefits Unlike encryption, which scrambles data, Tokenization helps organizations meet tokenization maintains the original data format. compliance requirements by removing the need This enables continued functionality of to store or process sensitive data directly. This applications and systems that rely on the lowers the burden of security and auditing for structure of the data. regulated data. Obfuscation 1 Obscuring Data 2 Complexity and Confusion Obfuscation transforms data into a form Obfuscation techniques introduce that is difficult to understand or analyze, complexity, misleading code structures, and without changing its underlying random variable names to confuse and functionality. deter potential attackers. 3 Preserving Usability 4 Layered Security Unlike encryption, obfuscation maintains Obfuscation is often used in conjunction the data's original format and structure, with other security methods like encryption allowing applications to continue operating and access controls for a multilayered normally. defense. Segmentation 1 Logical Data 2 Granular Access 3 Breach Divisions Control Containment Segmentation involves By segmenting data, If a breach occurs, data logically partitioning data organizations can apply segmentation limits the into distinct, non- tailored access exposure and impact, overlapping categories or permissions and security preventing unauthorized groups based on specific measures to each access to the entire criteria. segment, enhancing dataset. overall data protection. Permission Restrictions User-based Data Temporal Geo-Fencing Access Classification Restrictions Restrict data access Restrict data access Classify data into Limit data access and and usage to based on individual sensitivity levels, such usage to specific time authorized geographic user roles, as public, confidential, periods, preventing locations or IP address responsibilities, and or restricted.
