Learn Kubernetes Security
Secure your container environment against cyberattacks and deliver robust deployments with this practical guide
Key Features
* Explore a variety of Kubernetes components that help you to prevent cyberattacks
* Perform effective resource management and monitoring with Prometheus and built-in Kubernetes tools
* Learn techniques to prevent attackers from compromising applications and accessing resources for crypto-coin mining
Book Description
Kubernetes is an open source orchestration platform for managing containerized applications. Despite widespread adoption of the technology, DevOps engineers might be unaware of the pitfalls of containerized environments. With this comprehensive book, you'll learn how to use the different security integrations available on the Kubernetes platform to safeguard your deployments in a variety of scenarios.
Learn Kubernetes Security starts by taking you through the Kubernetes architecture and the networking model. You'll then learn about the Kubernetes threat model and get to grips with securing clusters. Throughout the book, you'll cover various security aspects such as authentication, authorization, image scanning, and resource monitoring. As you advance, you'll learn about securing cluster components (the kube-apiserver, CoreDNS, and kubelet) and pods (hardening image, security context, and PodSecurityPolicy). With the help of hands-on examples, you'll also learn how to use open source tools such as Anchore, Prometheus, OPA, and Falco to protect your deployments.
By the end of this Kubernetes book, you'll have gained a solid understanding of container security and be able to protect your clusters from cyberattacks and mitigate cybersecurity threats.

Analysis of computer virus propagation behaviors over complex networks: a case study of Oregon routing network
This paper mainly aims to explore the propagation behaviors of computer virus over complex networks under the combined effects of network topology and removable storage media. To this end, a dynamical model is established and analyzed theoretically, including the outbreak threshold, equilibria and their global dynamics. It is found from the systematic analysis that the virus will die out or persist in the network depending on the outbreak threshold, which is associated with the network topology and removable storage media. Moreover, a set of well-designed experiments are performed over the Oregon routing network to verify the proposed model and its theoretical analysis results. Experimental results show that the predicted results of the model are in good agreement with the simulation results over the above network, and the removable storage media have a great effect on viral spread. To this regard, some preventive measures against virus infection are recommended.

Stochastic fractional order model for the computational analysis of computer virus
This work presents a novel mathematical framework for analyzing the propagation dynamics of computer viruses by formulating a fractional-order model. The classical integer-order differential model of computer virus spread is reformulated using Caputo fractional derivatives, yielding a fractional computer virus model that captures the inherent memory and persistence characteristics of digital infection processes. A comprehensive analytical investigation is conducted, including the verification of fundamental properties such as positivity and boundedness of the system. The existence and uniqueness of the solutions are rigorously established using the Banach fixed-point theorem. The model exhibits two equilibrium states whose global stability is thoroughly analyzed. To incorporate the stochastic behavior of networked systems, such as fluctuating traffic, random user activity, and unpredictable system responses, the fractional computer virus model is extended into a stochastic fractional computer virus model by introducing white noise terms. Unlike previous studies, which often neglect the combined impact of stochasticity and memory, this research provides a rigorous treatment of both, ensuring the unique solvability of the stochastic fractional computer virus model. A Grunwald–Letnikov-based nonstandard finite difference scheme is developed to obtain reliable numerical approximations of the model while preserving essential qualitative features such as solution positivity and boundedness. Numerical simulations, based on realistic test scenarios, support the theoretical findings and illustrate the complex dynamics introduced by both fractional-order behavior and stochastic influences. This study provides a robust and realistic framework for understanding and predicting the spread of computer viruses in complex digital environments.

A Numerical Study Based on Haar Wavelet Collocation Methods of Fractional-Order Antidotal Computer Virus Model
Computer networks can be alerted to possible viruses by using kill signals, which reduces the risk of virus spreading. To analyze the effect of kill signal nodes on virus propagation, we use a fractional-order SIRA model using Caputo derivatives. In our model, we show how a computer virus spreads in a vulnerable system and how it is countered by an antidote. Using the Caputo operator, we fractionalized the model after examining it in deterministic form. The fixed point theory of Schauder and Banach is applied to the model under consideration to determine whether there exists at least one solution and whether the solution is unique. In order to calculate the approximate solution to the model, a general numerical algorithm is established primarily based on Haar collocations and Broyden’s method. In addition to being mathematically fast, the proposed method is also straightforward and applicable to different mathematical models.
