User rights in IT teams: guide for developers

Introduction

In the IT and software development sector, managing user rights within teams is much more than a simple matter of internal organisation. It determines systems security, regulatory compliance and collective productivity. According to an IBM Security study in 2024, 74% of data breaches involve abuse or theft of privileged access rights. Faced with teams that are often distributed, multi-project and highly automated, defining who has access to what — and why — has become a strategic priority. This article guides you step by step through structuring user rights: authorisation models, operational best practices, integration into development workflows and impact on electronic signature of technical deliverables.

Understanding access rights management models

Before configuring anything, it is essential to choose the right conceptual model for rights management. Each IT team architecture calls for a different paradigm.

The RBAC model: the industry standard

Role-Based Access Control (RBAC) is the most widely used model in development environments. It consists of assigning permissions not to individuals directly, but to predefined roles (junior developer, tech lead, DevOps engineer, system administrator, etc.), and then associating each user with one or more roles.

Advantages of RBAC:

• Simplified management during arrivals/departures (offboarding)
• Clear auditability: you know exactly what each role can do
• Reduced risk of unintentional privilege escalation

In practice, a junior developer will only have access to development and staging environments, never production. A tech lead can validate pull requests and trigger CI/CD pipelines, whilst only the senior DevOps administrator will have access to production secret keys.

The ABAC model for complex environments

Attribute-Based Access Control (ABAC) goes further than RBAC by conditioning rights to contextual attributes: user location, connection time, project classification, code repository sensitivity. This model is particularly suited to teams managing projects for clients in the financial, healthcare or defence sectors, where compartmentalisation requirements are maximum.

Concretely, an engineer can have access to a Git repository in the morning from company offices, but be denied access over the weekend from an unapproved residential IP address — even with an identical role.

The principle of least privilege as a guiding thread

Regardless of the model chosen, the principle of least privilege (Least Privilege Principle) must guide all access policies. This principle, set out in ANSSI recommendations and formalised in ISO/IEC 27001 standard, states that each user or process should have only the rights strictly necessary to carry out their duties.

In a DevOps context, this notably implies never sharing generic service accounts, using secrets with limited lifespan (ephemeral tokens), and never granting administrator rights by default.

Structuring rights by environment and project

A software development team rarely works on a single project or environment. The segmentation of rights must reflect this operational reality.

Segregating dev, staging and production environments

Strict separation of environments is a fundamental best practice. In most mature teams, rights are structured as follows:

• Development environment: accessible to all developers on the project, with broad permissions to encourage experimentation
• Staging/testing environment: access restricted to senior developers and QA engineers; no manual deployment possible without validation
• Production environment: access reserved for system administrators and automated pipelines (CI/CD) with mandatory multi-factor authentication

This segmentation drastically reduces the attack surface and limits the consequences of a compromised account.

Managing rights in collaborative development tools

Platforms such as GitHub, GitLab or Bitbucket offer granular rights systems that deserve careful attention. On GitHub Enterprise, for example, permission levels include: Read, Triage, Write, Maintain and Admin — each with precisely defined capabilities.

Best practice: define a RACI matrix of access for each critical repository, formalised in your project's internal documentation. This matrix records who is Responsible, Accountable, Consulted and Informed for each type of action on the repository.

For project management tools (Jira, Linear, Notion), also remember to apply the same level of rigour: an external contractor should only access tickets that concern them, never the complete strategic roadmap.

Automating rights management in CI/CD pipelines

Rights are not limited to humans. In a modern architecture, service accounts, API tokens and CI/CD agents are as many non-human entities that have permissions. Their management is often neglected and constitutes a major attack vector.

Practical recommendations:

• Use a dedicated secrets manager (HashiCorp Vault, AWS Secrets Manager, Azure Key Vault) rather than plain text environment variables
• Configure API tokens with short lifespan and automatic rotation
• Regularly audit service account rights and remove those that are no longer used

These practices are part of an approach to document compliance and traceability that Certyneo supports notably through electronic signature of internal security policies.

Integrating rights management into the employee lifecycle

Rights management is not a static configuration: it must evolve continuously with changes in the team.

Structured onboarding process

The arrival of a new developer or contractor must trigger a formalised access rights attribution process, ideally automated via an Identity Governance and Administration (IGA) tool or, at minimum, via an access request form with managerial validation.

Automatic provisioning from the HR system (via SCIM connectors to Active Directory, Okta or Google Workspace) ensures that rights are granted on day one and above all revoked on the last day. According to a Ponemon Institute survey (2023), 58% of enterprises admit that former employees can still access systems after their departure.

This onboarding process often includes signing IT charters, security policies or confidentiality clauses — documents for which electronic signature in the enterprise offers irreproachable legal traceability.

Periodic access reviews (Access Reviews)

DORA (Digital Operational Resilience Act) and security frameworks such as SOC 2 or ISO 27001 require periodic reviews of access rights — generally quarterly or semi-annually. These audits consist of asking each manager to confirm or revoke the rights of each team member.

These reviews must be documented and traceable. Electronic signature of access rights audit reports is a best practice to guarantee their integrity and non-repudiation — a subject detailed in our comprehensive electronic signature guide.

Managing special cases: contractors, freelancers and interns

External parties present a specific challenge. They need sufficient access to work effectively, but must be compartmentalised from sensitive data and critical systems.

Best practices:

• Create separate accounts for contractors (never share internal accounts)
• Apply automatic expiration dates on external accounts
• Restrict network access via a dedicated VPN or Zero Trust architecture
• Have a confidentiality agreement (NDA) signed before access — ideally via eIDAS-compliant electronic signature for maximum probative value

Compliance, audit and governance of rights in the IT team

Rights management is not just a technical configuration: it fits into a broader governance framework.

Maintaining an authorisation register

Any organisation handling personal data or managing critical systems must maintain an up-to-date authorisation register. This document lists, for each system and each application:

• The authorised users and their access levels
• The dates of attribution and review of rights
• Associated managerial validations

Under GDPR (article 32), this register forms part of the appropriate technical and organisational measures that the controller must demonstrate. Its absence can be sanctioned by the CNIL.

Access logging and monitoring

The simple fact of granting rights is not enough: you must monitor their use. SIEM (Security Information and Event Management) solutions such as Splunk, Elastic SIEM or Microsoft Sentinel allow you to detect abnormal behaviour: connection outside usual hours, mass file downloads, access to unusual resources.

The NIS2 Directive, transposed into French law at the end of 2024, requires essential and important entities (many of which are IT service providers and critical software publishers) to implement robust detection and logging capabilities.

The role of electronic signature in rights governance

Formalising access rights policies, user charters and confidentiality agreements through electronically signed documents significantly strengthens governance. Unlike a simple email agreement, a document signed with an eIDAS-compliant solution offers proof of integrity and identity that will be admissible in case of dispute.

Certyneo notably allows you to configure signature workflows with precise roles — for example, requiring the CISO to sign before putting a security policy into production — which integrates naturally into a mature rights management policy. You can also estimate the operational gains of this approach using the electronic signature ROI calculator.

Legal framework applicable to user rights management in IT teams

User rights management in an IT organisation is more than just a technical configuration matter: it is governed by a set of binding regulatory texts, the non-compliance with which exposes organisations to significant penalties.

GDPR — Regulation (EU) 2016/679

Article 5 of GDPR sets out the principle of data minimisation, which extends by analogy to the principle of minimisation of access: a user should only access data strictly necessary for their duties. Article 25 (data protection by design) and Article 32 (processing security) require the implementation of appropriate technical and organisational measures, amongst which access control is explicitly listed.

The CNIL clarified in its doctrine that non-compliance with authorisation rules constitutes a breach of Article 32. Fines of up to 4% of worldwide turnover or 20 million euros can be imposed.

NIS2 Directive — Directive (EU) 2022/2555

Transposed into French law by the law of 17 October 2024, the NIS2 Directive significantly widens the scope of entities subject to cybersecurity obligations. It now includes many software publishers, IT service providers and IT companies. Article 21 of NIS2 notably requires access control measures, identity management and logging of security events.

eIDAS Regulation — Regulation (EU) 910/2014 and eIDAS 2.0

For formal documentation of rights policies (charters, security policies, processing agreements), the eIDAS Regulation confers full legal value on qualified electronic signatures. Article 25 of the Regulation specifies that a qualified electronic signature has a legal effect equivalent to a handwritten signature. Article 26 defines the requirements applicable to advanced electronic signatures, notably the unique link with the signatory and detectability of any subsequent modification.

Employment law and employer obligations

Under French law, the employer is responsible for the security of computer systems made available to employees (Article L.4121-1 of the French Labour Code). The case law of the Court of Cassation has repeatedly confirmed that failure to control access engages the employer's liability in case of data breach. The internal regulations or IT charter, the validity of which is governed by Article L.1321-1 of the French Labour Code, must formalise the rules for use of systems and associated rights.

Use scenarios: rights management in IT teams

Scenario 1 — An IT service provider managing projects for multiple simultaneous clients

An IT services company of approximately 80 developers works simultaneously on around ten client projects, some of which are in regulated sectors (finance, healthcare). Before implementing a structured rights policy, access was managed ad hoc: developers retained access to old completed projects, and some API tokens were shared between multiple teams.

After deploying an IGA solution with RBAC-based rights attribution by project and integrating a centralised secrets manager, the company reduced orphaned access detected during quarterly audits by 65%. The time to revoke access at the end of assignments fell from 3 working days to less than 2 hours thanks to automated deprovisioning. Confidentiality charters signed electronically before each project access made it possible to build a documented file during a client audit in the banking sector.

Scenario 2 — A rapidly growing SaaS startup

A SaaS software startup grows from 12 to 45 developers in 18 months. Rapid growth generates an accumulation of uncontrolled access: departed interns still have repository access, temporary administrator rights granted to resolve an incident were never revoked.

By adopting a Zero Trust model combined with semi-annual access reviews formalised and electronically signed by tech leads, the startup reduced its attack surface by 40% (measured by the number of active access rights per user). Implementing a documented onboarding process — including electronic signature of the IT charter on day one — also strengthened the SOC 2 Type II compliance posture necessary for its North American clients.

Scenario 3 — Internal IT department of an industrial group

The IT department of an intermediate-sized industrial group (1,200 employees) manages a team of 35 people responsible for developing and maintaining critical business applications. During an ISO 27001 audit, it is found that access rights to production environments are not formally documented and no periodic review is conducted.

Implementation of an authorisation matrix, reviewed quarterly with each version electronically signed by the CISO and IT Director, made it possible to obtain ISO 27001 certification at the renewal audit. The processing time for access requests was reduced from 5 days to less than 4 hours thanks to an integrated digital workflow, reducing operational blockages and improving business team satisfaction.

Conclusion

Managing user rights in an IT and software development team is a central pillar of organisational security, compliance and productivity. By adopting a structured model — RBAC or ABAC depending on the complexity of your environment —, by applying the principle of least privilege, by automating the attribution and revocation of access, and by formally documenting your authorisation policies, you drastically reduce your risks whilst meeting the requirements of GDPR, NIS2 and frameworks such as ISO 27001.

Electronic signature plays an increasing role in this governance: IT charters, security policies, NDAs with contractors — so many documents for which Certyneo offers an eIDAS-compliant, traceable solution that integrates into your existing workflows.
