Currently, since March 2018, SSL/TLS certificates (more commonly called HTTPS certificate) can have a maximum lifetime of 825 days.
But in March 2020, Apple announced that they only will allow SSL/TLS certificates on Safari that have a maximum validity of 398 days (13 months). And Google will follow this path (announced by the chair emeritus of CA/B Forum on Twitter in June 2020, awaiting official announcement).
There are several types of IT security audits: organizational audits, technical audits and penetration testing.
All these variants are complementary and enable to analyze optimally an organization’s level of security. In this article, we will voluntarily leave aside the organizational audits in order to focus on the technical aspects of security audits.
Storing passwords securely is a recurring concern.
But what are the main methods, how do they work, and what are they worth against current password cracking techniques?
In this article we explain the main principles of secure storage (hash, salt, pepper, iteration) and highlight their importance for resisting password recovery methods. Finally, we will talk about a reliable hash function for secure storage.
The current trend is to strengthen the security requirements for customers, partners and investors. Security audits have been democratised to small and medium-sized companies, for whom they represent a prerequisite to be able to collaborate on IT issues with large companies. In fact, large accounts almost systematically integrate requests for security audit reports into their purchasing processes. The introduction of the GDPR 2 years ago also enabled companies to become aware of data security issues in business sectors where risk awareness was previously low. Security certifications (ISO 27001, HDS, PCI-DSS, SOC2, etc.) are increasingly popular among small and medium-sized companies, as a way of differentiating themselves and making security a quality issue.
Conducting a security audit has a cost. When companies are asked about the budget they devoted it, we often hear “between €10k and €20k”, sometimes a little more, sometimes a little less. However, there isn’t really a standard price for this type of service: it all depends on what is done, how, and by whom. If the main objective is to be able to show that a pentest has been done less than 6 months ago, it is possible to make concessions to respect an extremely limited budget.
Abraham Lincoln (repeating a woodsman) would have answered the question: what would you do if you had just six hours to chop down a tree? I would spend the first four hours sharpening my axe.
What does it tell us? That preparation is key.
You cannot protect what you don’t know, therefore knowing your attack surface is the first essential step to protect it efficiently.
Once you have decided to go for a pentest, you may wonder if it should target your production environment.
Depending on the risks, it can be appropriate to pentest either a production environment or a test environment. Below is a summary of the pros and cons for each alternative.
Vaadata is a start-up specialized in security audits. We are looking for a cybersecurity consultant (M/F) to join our team, at the interface between technical and business issues.
25 pages to know the existing and exploitable vulnerabilities on these technologies, as well as the means to counter or reduce the risks.
The OWASP Top 10 2017 introduces the risk of insufficient logging and monitoring. Indeed, inherent problems in this practice are often underestimated and misunderstood. But why is a seemingly simple task ending up being a crucial point of information system security?
