7. Data Backup and Recovery
Establish robust data backup procedures to ensure data can be restored in the event of a cyberattack or data loss incident.
8. Data Retention Policies
Implement data retention policies to manage the lifecycle of data and ensure that obsolete or unnecessary data is securely disposed of.
How Data Security Management Works
Data security management works by implementing a combination of technical controls, policies, and procedures to protect data assets.
This includes encryption, access controls, authentication mechanisms, intrusion detection systems, security audits, and incident response protocols.
The goal is to create a layered defence strategy that mitigates risks and prevents unauthorised access to sensitive information.
Why Data Security Management is Important
Data security management is vital for several reasons:
1. Protection of Confidential Information
Safeguarding sensitive data such as customer records, financial information, and intellectual property from theft or misuse.
2. Compliance with Regulations
Ensuring compliance with data protection laws and regulations, such as GDPR or HIPAA, to avoid legal and financial repercussions.
