A PASSI audit is an information systems security audit carried out by a service provider qualified by the National Information Systems Security Agency (ANSSI). This qualification attests to the competence and reliability of the service provider, as well as the quality of the audits it carries out.
Ziwit is a French group specializing in cybersecurity. It has a team of qualified and experienced experts who carry out PASSI audits.
Ziwit has recognized expertise in many areas of cybersecurity, including:
Security architecture is the set of elements that contribute to the security of information systems.
Ziwit can assess the consistency of an organization's security architecture, ensure it meets security requirements, and identify potential vulnerabilities.
For example, Ziwit can identify flaws in an organization's security architecture, such as insufficient network segmentation, inappropriate use of privileges, or lack of vulnerability management.
Security policies and procedures are documents that define the security rules and good practices to be respected.
Ziwit can assess the effectiveness of an organization's security policies and procedures, ensure they are implemented consistently, and identify any gaps.
For example, Ziwit can identify gaps in an organization's security policies and procedures, such as a lack of a password policy, an inadequate backup policy, or a lack of a business continuity plan.
Security controls are technical or organizational measures put in place to protect information systems.
Ziwit can assess the effectiveness of an organization's security controls, ensure they are implemented correctly, and identify any weaknesses.
For example, Ziwit can identify weaknesses in an organization's security controls, such as a lack of firewalls, inappropriate use of antivirus, or lack of access management.
Vulnerabilities are flaws in systems or applications that can be exploited by attackers to compromise security.
Ziwit can identify potential vulnerabilities in an organization's systems and applications, and assess their severity.
For example, Ziwit can identify vulnerabilities in an organization's systems and applications, such as a software flaw, an operating system flaw, or a database flaw.

PASSI audits are carried out by qualified and experienced professionals, who use proven methodologies. They allow organizations to have an objective assessment of their level of security, and to take the necessary corrective measures to improve it.
PASSI audits make it possible to identify vulnerabilities and security risks in information systems. This information is valuable to organizations, which can then take steps to mitigate or eliminate them.
PASSI audits result in an audit report which contains recommendations for corrective measures. These measures can be implemented by organizations to improve their information systems security.
PASSI audits make it possible to identify the security risks to which organizations are exposed. By analyzing them, organizations can better manage them and implement effective mitigation measures.
PASSI audits are mandatory for organizations covered by the ANSSI General Safety Regulations (RGS). This regulation applies to public bodies, private companies and associations whose activities are likely to harm national security.
By carrying out this type of audit, organizations can demonstrate that they comply with the requirements of the RGS.
PASSI audits help identify vulnerabilities and security risks. By correcting or mitigating them, organizations can reduce the risk of cyberattacks.
A cyberattack can result in serious consequences for an organization, such as loss of data, business disruption, or cost of damage.
By avoiding cyberattacks and their consequences, organizations can reduce security costs. A cyber attack can result in significant costs, such as damage repair costs, data loss costs, and communication costs of the cyber attack.
PASSI audits can help improve customer and partner confidence, by demonstrating that the organization takes security seriously. Customers and partners may be more inclined to do business with an organization that has effective security measures in place.
The conduct of a PASSI audit is defined by the ANSSI requirements framework. It consists of four main phases:
Phase 1 of a PASSI audit is a crucial step that helps define the foundations of the audit and guarantee its success. It consists of four main activities:
This meeting allows representatives of the organization and the service provider to meet and discuss the objectives, scope and expectations of the audit.
During this meeting, the stakeholders:
The audit provider collects preliminary information about the organization, such as its activities, structures, information systems and security policies.
This collection of information allows the audit service provider to:
The audit agreement is a legal document that specifies the terms of the audit, such as the objectives, scope, timetable, budget and responsibilities of the parties.
The agreement is important to ensure that both parties agree on the terms of the audit. It also helps prevent conflicts or misunderstandings.
The service provider develops an audit plan detailing the specific activities to be carried out, the methods and tools to be used.
The plan is an important document that allows the audit service provider to prepare effectively for the audit. It also helps ensure that the audit is conducted effectively and efficiently.
Phase 2 of a PASSI audit is a crucial step which makes it possible to identify risks and security vulnerabilities in information systems. It consists of three main activities:
The audit provider analyzes the organization's documents, such as security policies, business continuity plans and contracts with service providers.
During this analysis, the service provider is interested in several aspects of security policies, in particular:
The provider may also identify potential vulnerabilities in security policies, for example policies that:
The audit service provider carries out interviews with the organization's employees to gather their perception of security.
During these interviews, the audit service provider focuses on several aspects of security, including:
The audit service provider can identify risks linked to employee behavior, for example:
The service provider may perform technical tests, such as penetration tests or vulnerability tests, to identify security vulnerabilities.
During these tests, the service provider attempts to simulate a computer attack to test the resistance of information systems to attacks. It can identify security vulnerabilities in information systems, for example:
Phase 2 of a PASSI audit is an essential step which makes it possible to identify risks and security vulnerabilities in information systems.
Phase 3 of a PASSI audit involves writing an audit report that presents the results of the assessment. This report contains recommendations to improve the safety of the organization.
The audit report must be clear, concise and objective. It must contain the following information:
The introduction presents the audit and its objectives. In particular, it must include the following information:
This section presents the risks and security vulnerabilities identified during the assessment. In particular, it must include the following information:
This section presents recommendations to improve the safety of the organization. In particular, it must include the following information:
Recommendations must be realistic and achievable. They must be adapted to the needs and priorities of the organization.
Recommendations may cover different aspects of security, including:
The conclusion summarizes the main findings of the audit. In particular, it must include the following information:
Phase 4 of an audit consists of:
Monitoring recommendations is an essential activity in phase 4. It ensures that recommendations are implemented correctly and on time.
The provider can follow the recommendations in different ways, including:
Evaluating the implementation of recommendations ensures that they have a positive impact on the safety of the organization.
The audit provider can assess the implementation of the recommendations in different ways, including:
The audit service provider can provide assistance to the organization to improve its security, in particular by implementing security training for employees or helping to update information systems.
Here are some additional examples of activities that the audit service provider can carry out during phase 4 of a PASSI audit:
