Cybersécurité

Analyser les risques, mettre en œuvre les solutions

Solange Ghernaouti

Solange Ghernaouti's broad academic survey of cybersecurity — risk analysis, governance, technical and legal dimensions — the standard French university reference, now in its 7th edition.

Sécurité informatique

Principes et méthodes à l'usage des DSI, RSSI et administrateurs

Laurent Bloch, Christophe Wolfhugel

A principles-first treatment of information security for DSI, RSSI and sysadmins — architecture, cryptography, network defence and security policy — from two veteran French practitioners.

Read this if

Students, managers and RSSI who need the whole landscape: risk, governance, legal, organisational and technical defence in one structured textbook. Strong on the managerial and risk-analysis side that purely technical books skip.

System administrators, architects and RSSI who want the reasoning behind security decisions: why a given architecture, protocol or policy holds or fails. Strong on the systems-and-network engineering view.

Skip this if

Hands-on practitioners looking for attacks, tooling or labs. This is a survey and risk-management text, not a technical how-to; it explains the field rather than teaching you to break or build.

Beginners wanting a gentle on-ramp, or readers chasing the latest tooling — the book is principles-oriented and predates much of the cloud-native era.

Key takeaways

The reference French academic textbook on cybersecurity, regularly updated — useful precisely because it's broad and structured rather than deep.
Its strength is risk analysis and governance: how to frame, measure and organise security, not how to exploit a target.
Better as a course backbone or a manager's orientation than as a practitioner's bench reference.

A rare French book that explains the why of security architecture rather than cataloguing tools.
Aimed squarely at the people who run infrastructure — admins, architects, RSSI — not at red teamers.
Principles age slowly, but check the network and crypto specifics against current cloud and identity practice.

How they compare

Cybersécurité and Sécurité informatique are both rated 4/5 in our catalog. Pick by topic preference and reading style rather than by rating.

Cybersécurité is pitched at intermediate level. Sécurité informatique is pitched at advanced level. Read the easier one first if you're not yet comfortable with the topic.

Cybersécurité and Sécurité informatique both cover Foundations, Defensive, so reading them in sequence reinforces the same material from different angles.
