   Data center (Wikipedia)

   WikipediaPublished Oct 8, 2026Checked Oct 11, 2026

   “A data center is a physical room, building, or facility for storing, managing, and disseminating data and information, including computer systems and associated components, housing IT infrastructure, and training artificial intelligence. The United States' act of Congress, the Energy Independence and Security Act of 2007, defines a data center as "any facility that primarily contains electronic equipment used to process, store, and transmit digital information." This includes "a free-standing structure" or "a facility within a larger structure, that uses environmental control equipment to maintain the proper conditions for the operation of electronic equipment." According to IBM, data centers date back to the 1940s, with the U.S. military's Electrical Numerical Integrator and Computer (ENIAC) as an early example. Data centers have different models depending on their workloads.”

   A Survey of Emerging DDoS Threats in New Power Systems.

   Sensors (Basel, Switzerland) (Luo et al.)Published Feb 8, 2026Checked Oct 11, 2026

   “Although attack-chain models are standard for Advanced Persistent Threat (APT) analysis, they have seldom been applied to DDoS, which is often framed as a single-step volumetric assault. However, ubiquitous intelligence and ambient connectivity increasingly enable DDoS campaigns to unfold as multi-stage operations rather than isolated floods. In parallel, large language models (LLMs) create new opportunities to strengthen traditional DDoS defenses through richer contextual understanding. Reviewing incidents from 2019 to 2024, we propose a three-phase DDoS attack chain-preparation, development, and execution-that captures contemporary tactics and their dependencies on novel hardware, network architectures, and application protocols. We classify these patterns, contrast them with conventional DDoS, survey current defenses (anycast and scrubbing, BGP Flowspec, programmable data planes, adaptive ML detection, API hardening), and outline research directions in cross-layer telemetry, adversarially robust learning, automated mitigation orchestration, and cooperative takedown.”

   Cyber-resilient Intensive Care Unit: Ransomware is a Patient-safety Crisis-A Resource-stratified Approach for India.

   Indian journal of critical care medicine : peer-reviewed, official publication of Indian Society of Critical Care MediciPublished May 25, 2026Checked Oct 11, 2026

   “India faces a compounded risk-the 2022 All India Institute of Medical Sciences (AIIMS) Delhi ransomware attack exposed fragmented systems, an absence of post-incident clinical surveillance, and the operational reality that "Western" cybersecurity fixes do not translate directly to resource-variable settings. This Viewpoint reframes cyber-resilience as a bedside safety competency rather than an information technology (IT) concern and proposes a resource-stratified three-tier preparedness framework. Tier 1 defines minimum viable controls achievable by any ICU: Downtime kits, paper medication administration records (MARs), designated roles, and structured drills. Tier 2 adds targeted redundancy; tier 3 outlines advanced capabilities for tertiary centers. When digital systems fail, patient survival depends on analog competencies practiced before the crisis.How to cite this articleChoudhuri B, Prakash J, Pal B, Veenith T.

   Comprehensive security review and challenges for smart and power grids to prevent cyber-attacks in IoTs.

   “This SG offers resilient, adaptive, self-recovery, and sustainable power distribution. The recent past has seen a gradual shift from unidirectional power systems towards the SG's bi-directional model. However, these large, complex, and self-healing SG systems have numerous vulnerabilities that threaten the exchanged data and power control commands. Therefore, many research efforts have been directed towards the enhancement of the SG security. In this paper, an overview of threats, attacks, vulnerabilities, security measures, and limitations for the IoT-based SG are described. We also give detailed descriptions of the Supervisory Control and Data Acquisition (SCADA) architecture as well as cloud computing as critical components of the smart grids. Moreover, this survey paper discusses tools and methods for verifying security protocols. The outcomes indicate the necessity of ensuring Quality of Service (QoS) in various communication technologies and networks deployed in SGs. The findings also point to the significance of developing network models and middleware to enhance QoS of the smart grid networks, which collect various data from diverse smart components and sensors.”
