ISO 2700 For Database administrators

 For Database Administrators (DBAs), ISO/IEC 27001 (often loosely referred to as ISO 2700) provides the gold standard framework for securing organizational data. The core goal is to protect databases from breaches, unauthorized access, and data loss by strictly maintaining the Confidentiality, Integrity, and Availability (CIA) of information. 

Understanding the standard's impact involves looking at four core pillars:
1. Access and Identity Control
  • Principle of Least Privilege: Grant permissions only to the extent required for users to perform their jobs.
  • Privileged Access Rights (Annex A 8.2): Limit super-admin privileges (e.g., sysadmin or root) to an absolute minimum and closely monitor their usage.
  • Segregation of Duties: Ensure developers and DBAs cannot push code/schema changes to production without peer reviews or management approval 
2. Data Protection and Masking
  • Encryption: Protect data at rest (using Transparent Data Encryption) and in transit (using TLS).
  • Data Masking: Prevent developers and QA engineers from viewing sensitive Personally Identifiable Information (PII) or financial data in non-production environments.
  • Cryptographic Keys (Annex A 8.24): Manage, rotate, and securely store encryption keys independently of the database files. 
3. Monitoring and Vulnerability Management
  • Audit Logging: Retain immutable, time-stamped logs of all database queries, schema changes, and login attempts.
  • Technical Vulnerabilities (Annex A 8.8): Perform routine patching, configure security baselines, and scan databases for known CVEs.
  • Real-Time Threat Detection: Implement tools like database firewalls to actively block SQL injections and unauthorized bulk exports.  
4. Backups and Business Continuity
  • Information Backup (Annex A 8.13): Enforce strict backup schedules, test data restoration procedures, and securely store offsite or immutable backup copies in case of ransomware or hardware failures.
Actionable DBA Tasks for ISO 27001 Compliance
  • Access Review: Conduct quarterly audits to remove terminated employees and revoke stale database accounts.
  • Hardening: Disable unnecessary database features, sample schemas, and extended stored procedures that can serve as attack vectors.
  • Vendor & Framework Resources: Reference the ISO 27001 Azure SQL Blueprint or the ISO 27001 Official Standard Guide for specific cloud and enterprise requirements

GOAL Goal of this document is to provide the method to purge the old records of Optimizer Statistics Advisor Task namely AUTO_STATS_ADVISOR_TASK that consumes huge SYSAUX space. Huge no.of old records retained in WRI$_ADV_OBJECTS for AUTO_STATS_ADVISOR_TASK or INDIVIDUAL_STATS_ADVISOR_TASK incurs heavy SYSAUX space. AUTO_STATS_ADVISOR_TASK is meant for Automatic Statistics Advisor task while INDIVIDUAL_STATS_ADVISOR_TASK is for Manual Statistics Advisor task.  DBA_ADVISOR_PARAMETERS displays all advisor task parameters and their current values in the database. There is a parameter name called EXECUTION_DAYS_TO_EXPIRE. This parameter is set in no.of days. Executions older than the value(no.of days) set would be purged automaticall...
