IT Security Audit
An IT security audit is a comprehensive assessment of a company’s technical and organizational safeguards, aiming to identify weaknesses, evaluate risks, and recommend actions to enhance the level of security.
The audit may cover IT infrastructure, systems, configurations, access management, and selected security processes and procedures.
We identify the most critical risk areas and indicate which actions should be taken first.
What Does an IT Security Audit Involve?
An IT security audit involves assessing an organization’s environment for weaknesses, irregularities, and risks that could impact the security of systems and data.
Its purpose is to determine the most critical risk areas, their potential significance for the organization, and which actions should be prioritized.
The audit should provide the organization with a basis for informed planning of changes, not just a list of detected problems.
What does a security audit cover?
The scope of an IT security audit may include infrastructure, systems, access management, backups, and processes and procedures affecting organizational security.
Depending on the project’s goal, we analyze, among other things:
- IT infrastructure – how key environmental elements, devices, and services are secured,
- systems and configuration – settings affecting security and potential configuration errors,
- access management – rules for granting, modifying, and revoking permissions,
- authentication – mechanisms used and rules for system access,
- backups – how backups are created, stored, and managed,
- security procedures – rules operating within the organization and their practical application,
- incident management – the organization’s preparedness to identify and handle security-related events.
The exact scope of the audit is determined before the project begins and is tailored to the organization’s environment and needs.
How is an IT Security Audit Conducted?
An IT security audit includes defining the scope, analyzing the environment, assessing risks, and preparing a report with recommendations.
1. Defining the objective and scope
We define which environment will be covered by the audit and which areas require special attention.
2. Environment and Security Analysis
We examine the defined elements of infrastructure and systems, and, if included in the scope, selected security procedures and processes.
We identify potential weaknesses, irregularities, and areas requiring further analysis.
3. Risk Assessment
We assess identified problems in the context of the organization’s environment and their potential impact on security.
This allows us to determine which of them should be prioritized.
4. Report and Recommendations
The audit concludes with a report containing the analysis results and recommendations for further actions.
What Do You Receive After a Security Audit?
After the audit, you receive a report describing identified weaknesses, an assessment of their significance, and recommendations for further actions.
The audit results help to:
- identify the most critical risk areas,
- prioritize corrective actions,
- better plan changes in security measures and processes,
- make security decisions based on the current state of the environment.
Thus, the audit can serve as a starting point for further organization and development of the organization’s security.
When Should a Security Audit Be Conducted?
A security audit is worth conducting when an organization wants to obtain an independent picture of its IT environment and identify the most critical risk areas.
It is particularly advisable to consider an audit:
- after major changes in the IT environment,
- after a security incident,
- when the infrastructure has not undergone a comprehensive assessment for a long time,
- as part of a periodic verification of the security level.
An audit can also be a good starting point when a company wants to improve its cybersecurity but is not yet clear on which actions to begin with.
Security Audit vs. Penetration Test
A security audit assesses the environment more broadly, while a penetration test focuses on the practical verification of vulnerabilities in a specific system, application, or infrastructure.
An audit can cover both technical safeguards and organizational processes. A pentest involves a controlled attempt to exploit vulnerabilities within a defined scope.
Both services can complement each other but address different needs.
Security Audit vs. NIS2, DORA, and ISO 27001 Requirements
An IT security audit focuses on the level of security and risks present in an organization, whereas a compliance audit verifies the fulfillment of requirements stemming from a specific regulation or standard.
If the project’s goal is compliance verification, please refer to the appropriate service:
FAQ
How Long Does an IT Security Audit Take?
The duration of an audit depends on the size and complexity of the environment, as well as the defined scope. The schedule is determined after understanding the infrastructure and areas to be analyzed.
Can an audit cover only a selected area of the infrastructure?
Yes. An audit can cover the entire environment or a specific area if the organization wishes to verify particular systems, processes, or infrastructure elements.
Does an audit require access to company systems?
The scope of required access depends on the type of audit and the areas being analyzed. Before starting the project, we determine what information and level of access will be needed to conduct the assessment.
How to Prepare Your Company for a Security Audit?
The extent of preparations depends on the project. Most often, basic information about the environment, architecture, systems, and existing security processes is needed. A detailed list is established before the audit begins.
How Often Should a Security Audit Be Conducted?
The frequency depends on the organization and changes occurring in its environment. An audit should be repeated periodically and after major infrastructure changes or significant security incidents.
Can recommended changes be implemented after the audit?
Yes, if the scope of cooperation also includes further actions. The audit results can form the basis for planning technical or organizational changes, or subsequent security tests.
Does a security audit cover NIS2, DORA, or ISO 27001 requirements?
A security audit may reveal problems that are also significant from the perspective of regulatory requirements, but a full compliance assessment with NIS2, DORA, ISO 27001, or other requirements should be carried out as part of a dedicated compliance audit.
