The WebSocket protocol is a protocol of the application layer of the OSI model, which enables to communicate in full duplex (a communication canal where the information can circulate simultaneously in both directions) between a client (a browser) and a web server. In two words, it allows to create real-time web applications, like instant messaging chat.

Penetration Testing for Fintech companies: what are the main challenges?

Fintech companies are generally more exposed to risks and more mature than the average in terms of cybersecurity. The nature of their activities implies the need to take into account the risks of fraud and cyberattacks right from the design of a new product.

The pentest then confronts the security choices and protections in place with the real threat. Depending on the nature of the product (payment solution, credit platform, banking management, private equity, etc.), the business stakes will be different. However, here are a few details on the main risks and the most frequent pentest priorities according to our experience with fintech companies.

When a good time pentest

Doing a pentest might be in your objectives… but it’s not the right time for now. This can be for various reasons: developments are in progress, or a migration is planned, or you don’t have a budget yet…
Considering the different priorities that must be respected, when is a good moment to do a penetration test?
We are going to see together different situations in which the question arises and we’ll give you the keys to choose if it is the right moment to run a pen test.

IT Security Audit

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 database

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.

Cybersecurity Issues for Businesses in 2020

Penetration Testing: Approach, Methodology, Types of Tests and Rates

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.

Doing a Pentest for Less Than €1,500

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.

Knowing its attack surface

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.
