ISO 27001 Compliance Checklist: Information Security Management Systems

Implementing ISO/IEC 27001 ISMS Controls

ISO/IEC 27001:2022 specifies requirements for establishing, implementing, and maintaining an Information Security Management System (ISMS). For SaaS platforms, achieving certification is a validation of data security standards. Compliance leads build risk logs, define acceptable use guidelines, and secure infrastructure. Maintaining active security reviews ensures the platform is ready for certification audits.

Database Schema for ISO 27001 Risk Registries

An ISMS requires tracking corporate risks, impact levels, and mitigation actions. The following database table maintains the risk register:

CREATE TABLE iso_risk_register (
  risk_id VARCHAR(32) PRIMARY KEY,
  description TEXT NOT NULL,
  impact_score INT CHECK (impact_score BETWEEN 1 AND 5),
  probability_score INT CHECK (probability_score BETWEEN 1 AND 5),
  mitigation_strategy TEXT NOT NULL,
  owner_email VARCHAR(128) NOT NULL,
  last_reviewed_at TIMESTAMP WITH TIME ZONE
);

This structure supports audit requirements, ensuring a 100% complete asset risk logging target.

Audit Intervals and Gap Resolution Rules

Maintaining ISO compliance requires scheduling internal reviews. Companies set a 12 months recommended recurrence interval for internal security audits. These reviews test access controls, employee training, and backup systems. If auditors identify gaps, engineering teams must resolve issues within a 10hr maximum resolution target, keeping database records protected against data modification risks.

ISO 27001 Access Control Config JSON

Security teams write automation configurations to verify access logs and remove inactive developer accounts:

{
  "compliance_framework": "ISO-27001-2022",
  "access_policy": {
    "mfa_enforced": true,
    "password_rotation_days": 90,
    "session_timeout_seconds": 1800,
    "automatic_deactivation_days": 30
  }
}

This JSON ensures corporate access systems comply with Annex A security controls.

Indian Cybersecurity Rules and ISMS Alignment

Under CERT-In guidelines, Indian startups must report cybersecurity incidents within six hours of detection. Compliance teams align ISO 27001 workflows with local reporting protocols, writing scripts to check system integrity. Saving incident logs in secure, partitioned cloud buckets protects the platform, verifying that data access histories follow corporate safety rules.

Annex A Security Controls Mapping and Risk Registers

Achieving ISO 27001 certification requires SaaS startups to build an Information Security Management System (ISMS). Product teams map database operations against Annex A security controls, covering cryptography, asset management, and access keys.

The risk register logs all identified system risks, tracking mitigation timelines. Conducting internal security audits and running VAPT tests twice a year ensures the platform passes ISO verification, building client trust.
