Keeping a Close Watch: Trend Micro Specialized Cybersecurity Report for Latin America and the Caribbean

The objective of the threat landscape regional analysis is to understand how entities from the region view ransomware, targeted attacks, scams, remote work setups, and the adoption of relatively new technologies as cybersecurity concerns, thereby adding valuable insights and a comprehensive perspective of common and differing threats across the region.

Survivor: A Fine-Grained Intrusion Response and Recovery Approach for Commodity Operating Systems

International audienceDespite the deployment of preventive security mechanisms to protect the assets and computing platforms of users, intrusions eventually occur. We propose a novel intrusion survivability approach to withstand ongoing intrusions. Our approach relies on an orchestration of fine-grained recovery and per-service responses (e.g., privileges removal). Such an approach may put the system into a degraded mode. This degraded mode prevents attackers to reinfect the system or to achieve their goals if they managed to reinfect it. It maintains the availability of core functions while waiting forpatches to be deployed. We devised a cost-sensitive response selection process to ensure that while the service is in a degraded mode, its core functions are still operating. We built a Linux-based prototype and evaluated the effectiveness of our approach against different types of intrusions. The results show that our solution removes the effects of the intrusions, that it can select appropriate responses, and that it allows services to survive when reinfected. In terms of performance overhead, in most cases, we observed a small overhead, except in the rare case of services that write many small files asynchronously in a burst, where we observed a higher but acceptable overhead
