Second part of the Top 20 mitigations for industrial environments. This part will focus on mitigations related to network architecture, industrial protocols, network configuration and vulnerability scanning.
In the industrial world, there are a large number of systems, equipment, networks, areas, ducts, cloud environments, IT-OT environments, etc. In recent years, the number of attacks on industrial environments has been growing exponentially, and not only on purely industrial environments, but also on corporate environments that are connected to industrial environments. These IT environments being access points for attackers due to this IT/OT connectivity.
Managing and predicting vulnerabilities has become an essential task for cybersecurity. The Exploit Prediction Scoring System (EPSS) is a methodology launched in 2019, which uses algorithms and threat intelligence data to predict the likelihood of a specific vulnerability being exploited by threat actors in a short space of time.
In an environment where organizations are faced with an increasing number of vulnerabilities, EPSS effectively prioritizes responses to vulnerabilities based on their risk of exploitation. Through meticulous information collection and analysis, this system offers an efficient view of the threats affecting the business, allowing organizations to act proactively. This article focuses on understanding EPSS, how it improves security posture, and best practices for its implementation.
The Hive ransomware (especially in its v5 version) stands out for its sophistication, and for the impact caused to hundreds of companies and organizations worldwide, bypassing conventional defenses and challenging analysts with its advanced techniques.
In this article, we unravel its features, from its encryption methods to its anti-analysis countermeasures, illustrating not only the threat it poses, but also how it can be combated. Through a technical analysis, it is intended to empower readers with the knowledge necessary to understand and ultimately defend against these types of threats.
