Know your level of exposure to cyber threats!


An audit can be defined as a methodical, independent and documented process to gather evidence, and to assess this evidence objectively in order to determine the extent to which previously defined criteria are met. So defined, audits yield a review, an appraisal, an inventory.

When it comes to ISS (Information Systems Security), for any organization, security is, and must be, a key governance issue. Faced with the multiplication of cyber attacks and increasingly sophisticated and targeted threats, it is unfortunately a fact that some firms can still be particularly vulnerable on cybersecurity issues. Synetis, with an offensive and defensive approach, is able to support SMEs and large companies from design to implementation, right through to Maintenance Repair & Overhaul (MRO) for their security environments.

An IT security audit contributes to the overall confidence of the firm by identifying the firm’s IT weaknesses or by reassuring the firm where there are no problems.

Synetis’ SSI Auditing Team is composed of intrusion experts with several years of experience in cybersecurity auditing. Each team member brings their expertise to bear, and participates in the development of skills and knowledge bases. Our expertise is to provide a clear, comprehensible and detailed diagnosis of the security of an information system and/or process. As such, and thanks to its recognized experience in security audits, Synetis can offer “customized” auditing services with a focus on getting pragmatic, actionable results to prevent intrusion risks.

You can count on Synetis consultants to make winning proposals, giving concrete advice to clients in compliance with economic, methodological, organizational, regulatory and technological criteria. Moreover, thanks to the broad and deep expertise of Synetis consultants and our multiple partnerships with the main security software companies on the market, we contribute daily to the improvement of security solutions. Discovering software vulnerabilities on software products, be these renowned market leaders or open-source or partner companies, simply via intelligence gathering on the Internet, our auditors carry out their missions with an ethical approach coupled with ongoing technology watching. Our auditors develop and share their tools with the community.

They pay particular attention to the quality of the work produced, the deliverables as well as the support they deliver to the customer. The deliverables produced by Synetis auditors are:

  • Rigorous, relevant, precise
  • Methodical and pragmatic
  • They deliver high added value and quality in the audited field.

Statistical cryptanalysis of passwords.

The health of an Information System is very strongly linked to the passwords it contains. Employees, application accounts, service accounts, administration accounts… All these keywords are highly prized and targeted by external and internal attackers. In spite of protective measures, identity federation and strong authentication, what is really happening with the passwords in a given database? And, are they compliant with your internal password policy?

A statistical cryptanalysis mission enables these secrets to be tested, and to extract the knowledge and levers needed to strengthen the policies and building blocks of a company’s information system, while at the same time enabling contextualized and recurring awareness.

A SYNETIS cryptanalysis mission, once-off or recurring (every 3 or 6 months), provides concrete statistics, indicators and metrics to decision-makers:

  1. How many user
  2. accounts can be compromised in X hours?
  3. How can a password be broken, by what method and how long would this take?
  4. What is the distribution of accounts that comply with the password policy?
  5. What is the ratio of accounts “*adm*”, “*svc*”, “*app*”, etc. that have been broken?
  6. What is the Top 10 passwords used by employees?
  7. What are the most commonly used “basic words”?
  8. What is the distribution of password lengths?
  9. What are the templates / patterns / masks mainly used by users?
  10. What is the overall robustness index for employee passwords (Standards, ANSSI, etc.)?
  11. How does my company compare to other companies in the same sector?
  12. How many passwords have already been leaked on the Internet or DarkWeb?
  13. What are the password-renewal habits of employees?
  14. What is the distribution of password policies and compromised users by AD domain?
  15. What is the cryptographic robustness and password policy of a given repository?

Recurring: how does the general level of security of company passwords evolve?
