Multi-Step Attack Detection Based on Pre-Trained Hidden Markov Models

Sensors, 2022
Currently, hidden Markov-based multi-step attack detection models are mainly trained using the unsupervised Baum–Welch algorithm. The Baum–Welch algorithm is sensitive to the initial values of model parameters.

DDoS Attack Detection and Attacker Identification

International Journal of Computer Applications, 2012
DDoS attack is a form of DoS attack in which attacker uses authorized user IP address to attack on a particular victim. Of the two types of attack it falls in the active category. The main aim of the attacker is to jam the resources in order to deny services to the recipient. The attacker can use several strategies to achieve this goal, one of which is

Clinical Insights Into Hypercalcemia of Malignancy in Childhood

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.
