User rights in IT teams: a guide for developers

Introduction

In the IT and software development sector, the management of user rights within teams is far more than a simple question of internal organisation. It determines systems security, regulatory compliance and collective productivity. According to an IBM Security study from 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 top-level strategic issue. 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 widespread model in development environments. It consists of assigning permissions not to individuals directly, but to predefined roles (junior developer, tech lead, DevOps engineer, systems 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 will be able to validate pull requests and trigger CI/CD pipelines, while 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 suitable for teams managing projects for clients in the financial, healthcare or defence sectors, where compartmentalisation requirements are maximum.

Concretely, an engineer may have access to a Git repository in the morning from the company's offices, but be denied that access on weekends from a non-approved 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 rights policies. This principle, inscribed in the ANSSI recommendations and formalised in the ISO/IEC 27001 standard, stipulates that each user or process should only have the rights strictly necessary to accomplish their missions.

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

Structuring rights by environment and by project

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

Partitioning dev, staging and production environments

Strict separation of environments is a fundamental best practice. In the majority of 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 systems administrators and automated pipelines (CI/CD) with mandatory multi-factor authentication

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

Managing rights in collaborative development tools

Platforms such as GitHub, GitLab or Bitbucket offer granular rights systems that deserve particular 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 the 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 think about applying the same level of rigour: an external contractor should only access the tickets that concern them, never the complete strategic roadmap.

Automating rights management in CI/CD pipelines

Rights do not only concern 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 secret manager (HashiCorp Vault, AWS Secrets Manager, Azure Key Vault) rather than plain text environment variables
• Configure API tokens with short lifespans with automatic rotation
• Regularly audit service account rights and remove those no longer in use

These practices are part of an approach to documentary compliance and traceability that Certyneo supports notably through the 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 should trigger a formalised process for attributing rights, 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 assigned on day one and especially revoked on the last day. According to a Ponemon Institute survey (2023), 58 % of companies admit that former employees can still access systems after they leave.

This onboarding process often includes the signature of IT charters, security policies or confidentiality clauses — documents for which enterprise electronic signature provides impeccable legal traceability.

Periodic reviews of rights (Access Reviews)

DORA (Digital Operational Resilience Act) and security frameworks such as SOC 2 or ISO 27001 require periodic reviews of access rights — usually quarterly or semi-annual. These audits involve 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 guide to electronic signature.

Managing special cases: contractors, freelancers and interns

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

Best practices:

• Create separate accounts for contractors (never share internal accounts)
• Apply automatic expiration dates to external accounts
• Restrict network access via a dedicated VPN or Zero Trust architecture
• Have them sign a confidentiality agreement (NDA) before any 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 limited to technical configuration: it is part of a broader governance framework.

Maintaining a record of authorisations

Any organisation processing personal data or managing critical systems must maintain an up-to-date record of authorisations. This document records, for each system and each application:

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

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

Logging and monitoring of access

Simply assigning rights is not enough: you must monitor their use. SIEM (Security Information and Event Management) solutions such as Splunk, Elastic SIEM or Microsoft Sentinel make it possible to detect abnormal behaviour: logon outside usual times, 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 documents signed electronically significantly strengthens governance. Unlike a simple email agreement, a document signed with an eIDAS-compliant solution offers evidence of integrity and identity that will be admissible in case of dispute.

Certyneo notably makes it possible to set up signature workflows with specific roles — for example, requiring the CISO to sign before a security policy is put into production — which naturally integrates 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

Managing user rights in an IT organisation is not just a matter of technical configuration: it is governed by a set of binding regulatory texts, ignorance of which exposes organisations to significant sanctions.

GDPR — Regulation (EU) 2016/679

Article 5 of the GDPR establishes the principle of data minimisation, which extends by analogy to the principle of access minimisation: a user should only have access to data strictly necessary for their missions. Article 25 (data protection by design) and article 32 (security of processing) require the implementation of appropriate technical and organisational measures, among which access control is explicitly mentioned.

The CNIL has specified in its doctrine that non-compliance with authorisation rules constitutes a breach of article 32. Fines of up to 4 % of global turnover or 20 million euros may be imposed.

NIS2 Directive — Directive (EU) 2022/2555

Transposed into French law by the law of 17 October 2024, the NIS2 Directive significantly broadens the scope of entities subject to cybersecurity obligations. It now includes many software publishers, IT service providers and IT services companies. Article 21 of NIS2 notably imposes measures for access control, 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 legal effect equivalent to a handwritten signature. Article 26 defines the requirements applicable to advanced electronic signatures, notably the uniqueness of the link with the signatory and the detectability of any subsequent modification.

Labour 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 Labour Code). The case law of the Court of Cassation has confirmed on several occasions 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 Labour Code, must formalise the rules for using systems and associated rights.

Use cases: user rights management in IT teams

Scenario 1 — An IT services company managing projects for multiple clients simultaneously

An IT services company of about 80 developers working simultaneously on a dozen 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 several teams.

After deploying an IGA solution with rights assignment based on RBAC roles per project and integration of a centralised secret manager, the company reduced 65 % of orphaned access detected in quarterly audits. The time to revoke access at the end of an assignment fell from 3 business days to less than 2 hours thanks to automation of deprovisioning. Confidentiality charters signed electronically before each project access made it possible to build a robust file during an audit by a banking sector client.

Scenario 2 — A SaaS startup in hypergrowth

A SaaS software startup goes from 12 to 45 developers in 18 months. Rapid growth creates an accumulation of uncontrolled rights: interns who have left still have access to repositories, administrator rights granted temporarily to resolve an incident but never revoked.

By adopting a Zero Trust model combined with formalised and electronically signed semi-annual access reviews by tech leads, the startup reduced its attack surface by 40 % (measured by the number of active access rights per user). The implementation of 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 — An internal IT department of an industrial group

The IT department of a medium-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 reviews are conducted.

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

Conclusion

Managing user rights in an IT and software development team is a central pillar of security, compliance and organisational 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 assignment and revocation of access, and by formally documenting your authorisation policies, you drastically reduce your risks while meeting the requirements of GDPR, NIS2 and frameworks such as ISO 27001.

Electronic signature is playing an increasingly important role in this governance: IT charters, security policies, NDAs with contractors — so many documents for which Certyneo offers an eIDAS-compliant, tracked and integrable solution into your existing workflows.
