Principles of Operation Security Intelligence at Identification of Sensitive Information

o The identification of sensitive information is a critical step in ensuring information security. It involves understanding the nature of sensitive data, its potential impact if compromised, and the appropriate security measures to protect it

o Identifying data, information, or assets that need protection, such as operational secrets, strategies, technologies, or organizational plans.

1. Comprehensive Data Inventory

· Identify and Categorize Data: Classify data by sensitivity level (e.g., low, medium, high) to understand its criticality or not for organisation.

· Track Data Flow: Monitor data’s journey from creation to disposal to identify potential vulnerabilities that depict in a data flow

· Map Data Storage: Determine where sensitive data resides, including physical and digital locations place of data storage

2. Risk Assessment and Prioritization

· Assess Potential Threats: Identify potential risks like cyberattacks, insider threats, and physical breaches.

· Evaluate Impact: Determine the potential consequences of a data breach, such as financial loss or reputational damage.

· Prioritize Security Efforts: Allocate resources and implement security measures based on risk levels.

3. Classification and Labeling

· Clearly Label Sensitive Data: Assign appropriate labels to indicate the sensitivity level and handling requirements.

· Ensure Consistent Labeling: Maintain consistent labeling standards across the organization.

· Regularly Review Labels: Update classification and labeling schemes to reflect changing data sensitivity and regulatory requirements.

4. Access Controls

· Limit Access: Grant access to sensitive information only to authorized individuals with a legitimate need.

· Implement Role-Based Access: Assign permissions based on users’ roles and responsibilities.

· Minimize Access: Grant users the minimum necessary access to perform their duties.

· Verify User Identity: Utilize strong authentication methods like multi-factor authentication.

5. Data Protection and Encryption

· Protect Data at Rest and in Transit: Encrypt sensitive data to prevent unauthorized access.

· Secure Data Storage: Use secure storage solutions like encrypted drives and secure cloud storage.

· Implement Data Backup and Recovery: Establish robust backup and recovery procedures to safeguard against data loss.

6. Monitoring and Logging

· Monitor Network and System Activity: Continuously monitor for potential threats.

· Analyze Logs: Examine logs to identify suspicious activity and potential security incidents.

· Utilize SIEM Tools: Correlate and analyze security events across different systems.

7. Incident Response Planning

· Establish an Incident Response Team: Create a dedicated team to handle security incidents.

· Develop an Incident Response Plan: Outline procedures for detecting, containing, eradicating, recovering from, and learning from security incidents.

· Test the Incident Response Plan: Conduct regular security drills and simulations.
