The Hacking Economy: Why Business Continuity is Crucial for SMEs

This article emphasizes the urgent need for small and medium-sized enterprises (SMEs) to prioritize business continuity in light of the rising threats from the hacking economy, which is projected to cost $10.5 trillion annually by 2025. SMEs are increasingly targeted due to their vulnerabilities and limited cybersecurity resources. Implementing a robust business continuity plan is essential for minimizing downtime, protecting sensitive data, and maintaining customer trust. The article also outlines actionable steps for SMEs to develop effective plans, such as conducting impact analyses and training employees. By prioritizing business continuity, SMEs can better prepare for cyber threats and ensure long-term resilience and success.

Cyber Attacks 101: vulnerabilities, exploitations, and defense lines

In this article, various forms of cyberattacks are explored, emphasizing the risks they pose to economic actors. The key attack methods discussed include Social Engineering, where attackers manipulate individuals to gain confidential information; Vulnerability Exploitation, exploiting weaknesses in systems; Bad Configurations, leading to accidental exposures; Password Cracking, using methods like brute force to access accounts; Eavesdropping, intercepting data over public WiFi; and Internal Attacks, threats from within an organization. The article highlights the importance of understanding these threats and implementing robust security measures to protect sensitive data and maintain digital continuity.

A failure showing how fragile is companies’ continuity around the world

On Friday, the world experienced a business interruption caused by the hasty deployment of a software update. This software, Crowdstrike, is deployed on many Windows environments and its failure touched approximately 8.5 million computers.

Unlock the Secrets to Managing Financial Risk from Ransomware

The guide leverages the Factor Analysis of Information Risk (FAIR) model, a cutting-edge framework that quantifies cyber risks in financial terms. Unlike qualitative models like NIST CSF, ISO/IEC 27001, OCTAVE, and COBIT, the FAIR model offers a detailed financial analysis, helping you prioritize risks based on their potential financial impact. This approach ensures you have a clear picture of the economic consequences of cyber threats, enabling more informed decision-making.

Advancing Multi-cloud Storage Security with Multi-party Threshold Schemes

The NIST Workshop on Multi-party Threshold Schemes (MPTS) 2023 was a landmark event that brought together experts from around the world to discuss advancements and future directions in cryptographic security. Among the distinguished speakers was Gilles Seghaier, our Chief Product Officer at Astran, whose insights captivated the audience and shed light on the pivotal role of multi-party threshold schemes in enhancing security for multi-cloud storage.

Adversarial Models in Cryptography

Let's take a deep dive into adversarial models in cryptography. Get an overview of the evolving nature of internet security, starting from its inception as a secure space to its current state where cyber-crime is prevalent. The distinctions are made between static vs. adaptive, classic vs. quantum, and computationally bounded vs. unbounded adversaries.

The New Era of Cyber Resilience: Surviving Ransomware with Astran

Astran is excited to announce its pioneering webinar, "The New Era of Business Resilience: Surviving Ransomware with Astran," scheduled for June 5, 2024. This event marks a significant milestone in advancing how businesses address and recover from cybersecurity threats, particularly ransomware.

Ransomware Warfare: Defending your Business and Bottom Line

Learn how to protect your organization from evolving ransomware threats with our latest ebook, "The CIO Guide for Surviving Ransomware." Gain insights, defensive strategies, and actionable advice to navigate the dynamic threat landscape with confidence.

Secret Sharing as used by Astran

In this blog, we will start by defining the various techniques we use in Astran S5 and explore some further applications present in the literature, such as Multiparty computing (MPC), and how we differ. The first technique is the All or Nothing Transform (AONT). The second one is the Shamir Secret Sharing. We will then explain how we combined these techniques to implement our zero-trust storage solution. Later, we will explain the Secure Multiparty Computation and how it works. And finally, how the Shamir Secret Sharing is used with the SMPC.

AONT: an essential gadget for Multi-Party Threshold Cryptography Workshop

In this presentation, we will focus on a multi-cloud storage security use case. We present a multiparty threshold protocol that leverages multiple cloud service providers (CSPs). Our solution allows a client to store data by sending it to a proxy, which splits it before spreading the shares amongst a set of CSPs. We make use of a combination of primitives, including Secret Sharing Schemes (SSS), All-Or-Nothing Transform (AONT), and an additive Homomorphic Encryption (HE) scheme.

Cloud’s data storage : Astran, first effective technical measure post Schrems II approved by the CNIL

Astran, the software editor building zero trust storage in the clouds, becomes the first effective technical measure approved by the French Data Protection Authority (CNIL) in the context of the use of non-European cloud solutions, in particular for data archiving and multi-party processing.
