1. Audit objectives and scope:
The primary task of information system security audit is to determine the audit objectives and scope, and make clear the information systems, network equipment and data storage and processing systems that need to be audited. Audit objectives may include system compliance, risk management, data security and network security.
2. Security policy and policy review:
Auditors will review the security strategies and policies of enterprises or organizations to assess whether they comply with national laws and regulations, industry standards and best practices. Including the review of the formulation process, effectiveness and implementation of safety policies.
3. User rights management audit:
User rights management is an important aspect of information system security. Auditors will review user accounts, roles and permissions to verify their rationality and security. This includes reviewing the process of creating and deleting user accounts, rights assignment and revocation control, password policy and account lockout.
4. Audit of system access control:
System access control is an important means to protect information system from unauthorized access, and auditors will evaluate the access control strategy and implementation of the system. Including user login process review, access authority verification, remote access control, operation logging and auditing.
5. Data security audit:
Data security is the core of information system security, and auditors will review data protection measures and compliance. Including data classification and encryption, backup and recovery, data transmission and storage security, data integrity and consistency.
6. System vulnerability scanning and vulnerability assessment:
In order to evaluate the security and risk of the system, the auditor will scan the vulnerabilities of the information system and evaluate its weaknesses. This includes using automated tools to scan the vulnerabilities and weaknesses of the system, and analyzing and evaluating them to determine the potential security problems in the system.

1. Security Incident Response Audit:
The purpose of security incident response audit is to evaluate the security incident response capability of enterprises or organizations, including security incident detection and reporting, emergency response process, incident traceability and investigation. By auditing the response process of security incidents, we can evaluate the timely response and recovery ability of enterprises or organizations to security incidents.

The report will include detailed audit results, risk assessment and suggested measures to help enterprises or organizations improve the security and compliance of their information systems.
Summary:
Information system security audit is a process of comprehensive inspection and evaluation of information systems of enterprises or organizations. By reviewing security policies, user rights management, system access control and data security, we can find potential security problems and put forward suggestions for improvement.
In addition, it can also evaluate the compliance of the system and the ability to deal with security incidents, and provide enterprises or organizations with effective measures to ensure the security of information systems.
