What is Data Security Lifecycle?

The importance of data security has witnessed exponential growth as organizations continue to generate and accumulate vast amounts of data. To safeguard this data against unauthorized access and malicious attacks, organizations must establish and maintain comprehensive security measures throughout the entire data lifecycle management.

Each stage of the cycle, including Creation, Storage, Usage, Sharing, Archival, and Destruction, necessitates meticulous consideration and implementation of appropriate security controls. This article offers an overview of the essential security measures that should be taken into account.

Data Creation

Data creation involves the generation of new data or modification of existing data. It encompasses a range of activities, such as gathering information from external sources or manually inputting data into a system. Throughout this process, it is crucial to consider security implications to guarantee the accuracy, reliability, and security of the data being created. For instance:

  • Gathering External Data: Ensuring the credibility and reliability of the source is crucial in the process of data collection from external sources. If the source is not trustworthy, it may compromise the accuracy of the resulting data. Additionally, data privacy considerations should be taken into account when dealing with third-party sources.
  • Manual Data Entry: Manual data entry poses risks as it is prone to human error, especially when dealing with large amounts of information. To ensure accuracy, important fields should be double-checked, and procedures should be implemented to detect and prevent malicious input. For instance, blocking or removing special characters or scripts before entering them into the system can help prevent injection attacks.
  • Data Validation: To ensure the validity and accuracy of incoming data, it is essential to subject it to a validation process before storing it in a database. This helps minimize errors and inconsistencies in the dataset by ensuring that only valid values are accepted for each field. Additionally, it safeguards sensitive information within the database by restricting access to authorized users.
  • Data Classification: Data classification should be performed promptly upon obtaining the data to provide organizations with clear guidelines on handling the information. It ensures the adequate protection of sensitive information and restricts access data to authorized personnel. The commonly used classifications for data are public, internal, confidential, and secret.

Data Storage

Safely and securely storing digital data is a crucial process that involves various methods. Cloud storage, hard drives, USB flash drives, and other external memory devices can be utilized to ensure information security. This data encompasses a wide range, from text documents and photos to large datasets generated by web applications. To maintain the confidentiality of this data, it is essential to implement effective security measures. Here are some key considerations:

  • Encrypting Sensitive Data: Encryption is paramount when it comes to data storage. By encrypting sensitive information, only authorized users can access it, making it challenging for unauthorized individuals to gain entry. The Advanced Encryption Standard (AES), which employs symmetric key algorithms, is widely used for secure encryption and decryption of files or messages transmitted over the internet. Additionally, Transport Layer Security (TLS) can provide an extra layer of protection when transmitting data over networks.
  • Monitoring Data Activity: Regularly monitoring data activity helps identify and address any suspicious behavior or potential data breach promptly. By observing data usage patterns, organizations and individuals can quickly detect anomalies and take necessary measures to safeguard and protect data from cybercriminals and other threats.

By implementing these measures, data can be stored securely, ensuring its integrity and confidentiality are protected.

Data Usage

Data usage refers to the utilization of data for various purposes. For instance, when a company collects customer information, they can leverage this data for marketing, customer service, product development, and more. This information collection enables organizations to gain insights into user behavior patterns and demographic trends, facilitating a better understanding of their target audience and customers. During data usage, it is vital to consider certain security measures:

  • Implementing Access Controls: Access controls help manage user privileges within an organization by defining who has access to specific data. By implementing role-based security measures, access to sensitive information can be limited to only those who require it. This not only safeguards confidential data but also provides protection against unauthorized access attempts by malicious actors.
  • Data Loss Prevention: Data loss prevention involves safeguarding confidential data by preventing unauthorized access, accidental or intentional modification, deletion, or transfer. DLP systems can monitor network activity for any suspicious behavior and notify administrators of any violations. This proactive approach helps protect against accidental and malicious breaches of confidential data.
  • Data Masking and Tokenization: Data masking and tokenization are techniques used to protect sensitive information. Data masking replaces original values with randomized values, while tokenization encrypts data in an unreadable format and stores it separately. Both methods minimize the risk of theft or misuse of sensitive user information, ensuring the security of your data.

Data Sharing

Data sharing involves the exchange of information between multiple parties, which can be done through various methods such as granting physical access to a dataset or utilizing cloud providers. The main objective of data sharing is to ensure that valuable information is shared among relevant parties, fostering better decision-making and collaboration. When engaging in data sharing, it is important to consider the following:

  • Non-disclosure agreements (NDA): When sharing sensitive information, it is advisable to establish a non-disclosure agreement (NDA). This practice safeguards confidential data, including intellectual property, customer data, and trade secrets, from unauthorized disclosure or misuse by external sources.
  • Secure File Sharing Platforms: To transmit large files containing confidential information, it is recommended to use secure file sharing platforms instead of email. These platforms include services like Dropbox, Google Drive, Box, as well as private cloud solutions designed for secure file exchanges between organizations, such as ShareFile or HighQ Collaborate.
  • Information Rights Management Solutions: Information Rights Management (IRM) solutions enable control over access, usage, and modifications of digital documents or records over time. These solutions can be employed in conjunction with secure file sharing platforms mentioned earlier, providing additional protection against unauthorized changes or distribution of confidential documents or records exchanged between parties.

By considering these factors, data sharing can be done in a secure and efficient manner, promoting effective collaboration and safeguarding confidential information.

Data Archival

Data archival or data retention involves storing data in an appropriate format for long-term retention and accessibility. Proper data archiving optimizes storage and retrieval operations while safeguarding confidential information. Here are some key security considerations:

  • Compliance with laws and regulations: Certain laws and regulations may require the archiving or retention of specific data for a minimum period. For example, customer account data is often subject to data retention under laws like the Sarbanes-Oxley Act in the United States and GDPR in the EU. Before archiving any data, ensure compliance with rules regarding retention duration and security measures.
  • Choice of online or offline storage: When deciding between online and offline storage for digital records, consider security implications. Online storage offers greater accessibility but requires careful selection of a reliable cloud provider. Offline storage may provide more secure solutions but can present challenges related to physical location and accessibility.
  • Data integrity: To ensure the accuracy of archived documents or records over time, implement regular backups and store multiple copies in different locations. This safeguards against potential loss or corruption. Depending on your organization’s needs, consider using checksums and hash functions as additional protection against tampering or corruption during long-term storage.

Data Destruction

Once the purpose of keeping a specific set of digital records has been fulfilled, it is crucial to securely destroy them. This can be achieved through various means, including:

  • Chain of Custody: Maintaining proper chain of custody practices is essential for ensuring security and accountability during the destruction of digital records. A chain of custody document should be utilized to record all actual processes involved in the destruction, including details such as document access prior to destruction, the method of destruction, and the responsible party overseeing the process.
  • Secure Disposal: When disposing of digital media, such as hard drives and storage devices, it is imperative to adhere to industry standards and perform secure disposal. Physical destruction methods, such as shredding or degaussing, can effectively prevent any compromise of recovered files.
  • Cryptographic Erasure: Cryptographic erasure, also known as Crypto Erase, is a secure data deletion process applied to storage devices. The data is encrypted, and instead of deleting the data itself, the encryption key is discarded. This ensures that the data remains inaccessible and secure without the encryption key.

It is important to note that comprehensive security controls should be implemented throughout the entire lifecycle of data, rather than solely during specific stages. This includes encrypting data throughout the lifecycle and ensuring that only authorized users can access the data at any given time.

Furthermore, performing comprehensive data analysis and security assessment can offer valuable insights into the handling of sensitive information, the data flow within the organization’s systems, and the effectiveness of existing policies in mitigating data risk. This evaluation helps to ensure the adequacy and robustness of the organization’s security measures. By understanding the current state of data security, organizations can take necessary steps to ensure the ongoing security of their data.

The Role of a Data Owner in the Data Security Lifecycle

The data owner plays a crucial role in the lifecycle of data security, carrying the responsibility for safeguarding and ensuring compliance with data protection measures at every stage. As the custodian of information, the data owner sets the rules for data access, usage, and sharing, ensuring that only authorized personnel can interact with the data.

They are also instrumental in determining the lifespan of the data, which includes its archival and eventual destruction, thus maintaining control over the data throughout its lifecycle. In essence, the data owner’s involvement is indispensable for an effective data security strategy, as they facilitate the holistic protection of data from inception to retirement.


In conclusion, data security is paramount in today’s digital age. As information becomes increasingly stored digitally, it is crucial to implement robust measures throughout the data security lifecycle. This ensures protection against unauthorized access and malicious attacks.
