July 22, 2024 • César Daniel Barreto
The contemporary information age has resulted in huge volumes of data that are collected and warehoused. This represents personal information and business intelligence critical to operating, decision-making, and strategic activities.
Managing and protecting this sea of data demands a defined organizational role: that of a Data Custodian. This article looks into the responsibilities, the need for, and best practices in data custodianship.
Who is a Data Custodian?
A Data Custodian refers to a person or a group heading the technical environment and operational aspects of data management within an organization. While the Data Owner dictates the purpose and policy of the data, the Data Custodian is concerned with the practical issues of storing, maintaining, and protecting the data in everyday life.
The major responsibilities of a Data Custodian are:
- Storing and maintaining data: Data Custodians ensure that data is stored appropriately and effectively. This shall include the selection of suitable storage solutions, management of databases, and making sure that data gets backed up regularly to prevent loss.
- Data Security: The primary role is to protect the data from unauthorized access, breaches, and various security threats. The Data Custodians implement these security measures through encryption and other security measures such as access controls and firewalls.
- Data Integrity: Data integrity is the requirement that ensures that the data is accurate, consistent, and reliable throughout its life cycle. This is achieved through appropriate validation procedures and routine auditing of data for discrepancies by the Data Custodians, who solve these inconsistencies.
- Availability of Data: This is considered as the availability of data to authorized users when required. The Data Custodians see to it that the management of user permissions and the procedure for retrieving data is efficient and reliable.
- Compliance: The data custodians ensure that data management practices comply with the concerned laws, regulations, and industry standards. These include the GDPR, HIPAA, and other laws set out for the protection of data.
Importance of a Data Custodian
- Protecting Sensitive Information: A Data Custodian becomes very important in an environment with proliferating threats of cyber attacks. He has the responsibility to safeguard sensitive and confidential information against breaches and other unauthorized access.
- Business Continuity: Proper data management and backup practices in place by Data Custodians ensure that in the case of a disaster or failure of a system, it would be restorable quickly, so as to minimize the period of downtime and disruption caused.
- Regulatory Compliance: Data Custodians keep an organization compliant with various acts and regulations on data protection, hence evading possible legal penalties and reputational damage.
- Improving Data Quality: High-quality data is possible only if Data Custodians take care of the integrity and accuracy of the data. This enables better decision-making at all levels of business operations.
Best Practices of Data Custodianship
- Implement Robust Security Measures: The Data Custodian should have in place comprehensive security protocols, which involve multi-factor authentication, encryption, and periodic security risk assessments to prevent threats to data.
- Regular Backups of Data: Automatic backup at regular intervals avoids loss of data due to accidental deletion by the user, hardware failure, or even cyber-attacks.
- Data Lifecycle Management: Data has to be properly managed from creation to destruction based on its importance and regulatory compliance.
- User Training and Awareness: It educates users on good data security practices and explains their role in keeping data safe. This can be prevented through periodic programs for training, which will eliminate human errors leading to leakage or loss of data.
- Collaborative effort with Data Owners: The Data Custodians should collaborate with the Data Owners in knowing the use and purpose of the data and other compliance requirements so that the management of data is aligned with the goals and objectives of the organization.
Conclusion
Data Custodian is a position very important in today’s data-driven world. It involves the safekeeping of valuable information assets, ensuring business continuity, and enabling compliance through proper storage, security, and management of data. Looking ahead into the future, with organizations continuing to produce ever-increasing volumes of data and relying on them for their operations, the role of the Data Custodian will only continue to rise in importance, thus remaining one of the core functions within any data-centric enterprise.
