Are there any constraints known that bear on the ability to perform Linux Security work? How is the team addressing them? How do we maintain Linux Security's Integrity? Are there any specific expectations or concerns about the Linux Security team, Linux Security itself? How will the Linux Security team and the organization measure complete success of Linux Security? Who will be responsible for documenting the Linux Security requirements in detail? Defining, designing, creating, and implementing a process to solve a business challenge or meet a business objective is the most valuable role... In EVERY company, organization and department. Unless you are talking a one-time, single-use project within a business, there should be a process. Whether that process is managed and implemented by humans, AI, or a combination of the two, it needs to be designed by someone with a complex enough perspective to ask the right questions. Someone capable of asking the right questions and step back and say, 'What are we really trying to accomplish here? And is there a different way to look at it?' For more than twenty years, The Art of Service's Self-Assessments empower people who can do just that - whether their title is marketer, entrepreneur, manager, salesperson, consultant, business process manager, executive assistant, IT Manager, CxO etc... - they are the people who rule the future. They are people who watch the process as it happens, and ask the right questions to make the process work better. This book is for managers, advisors, consultants, specialists, professionals and anyone interested in Linux Security assessment. Featuring 608 new and updated case-based questions, organized into seven core areas of process design, this Self-Assessment will help you identify areas in which Linux Security improvements can be made.

Enhance Linux security, application platforms, and virtualization solutions with SELinux 3 to work within your boundaries, your rules, and your policies Key FeaturesLearn what SELinux is, and how it acts as a mandatory access control system on LinuxApply and tune SELinux enforcement to users, applications, platforms, and virtualization solutionsUse real-life examples and custom policies to strengthen the security posture of your systemsBook Description Linux is a dominant player in many organizations and in the cloud. Securing the Linux environment is extremely important for any organization, and Security-Enhanced Linux (SELinux) acts as an additional layer to Linux system security. SELinux System Administration covers basic SELinux concepts and shows you how to enhance Linux system protection measures. You will get to grips with SELinux and understand how it is integrated. As you progress, you'll get hands-on experience of tuning and configuring SELinux and integrating it into day-to-day administration tasks such as user management, network management, and application maintenance. Platforms such as Kubernetes, system services like systemd, and virtualization solutions like libvirt and Xen, all of which offer SELinux-specific controls, will be explained effectively so that you understand how to apply and configure SELinux within these applications. If applications do not exert the expected behavior, you'll learn how to fine-tune policies to securely host these applications. In case no policies exist, the book will guide you through developing custom policies on your own. By the end of this Linux book, you'll be able to harden any Linux system using SELinux to suit your needs and fine-tune existing policies and develop custom ones to protect any app and service running on your Linux systems.

This book was written by IBM® IT specialists who have experience implementing IBM Z® solutions, especially Linux on IBM LinuxONETM (LinuxONE) or IBM Z servers. Therefore, the content of this book follows the guidelines from Linux and IBM z/VM® regarding LinuxONE and IBM Z installations. The preferred practices described in this book are gathered from the experiences of those specialists in hundreds of projects at IBM and customer environments. This publication provides you with all of the information that you need to decide the best scaling architecture when implementing Linux on IBM Z or LinuxONE. This book has the following goals: To inform you about x86 sprawl problems To inform you that x86 Vertical Scale out architectures are problematic going forward To provide solutions to x86 server sprawl problems To inform you about the LinuxONE and IBM Z differentiation for each x86 server sprawl problem To provide virtulization and security options for LinuxOne and IBM Z The scaling up and scaling out architectures enable you to scale the capacity of an existing system to attend a sporadic application demand or an application workload. This gives you some freedom to operate in the environment. However, if this activity is performed without correct planning and the correct architecture choice, it leads to a server sprawl situation where your environment houses more servers than it should based on its current and predicted requirements. Although scaling out on x86 systems is a common form of scaling because of their popularity, the x86 systems were originally designed as cheap computers. Unfortunately, the scale out on x86 can easily become a problem in terms of total cost of ownership (TCO) when the environment starts to increase in terms of number of physical servers. The LinuxONE and IBM Z servers solve the sprawl problem caused by the scaling out of x86 servers, and are an excellent choice for cloud, mobile, big data, blockchain, analytics, and other workloads that require a robust and flexible environment. This publication describes the advantages and disadvantages of the scaling options. The audience of this publication consists of the following groups: Customers, IBM Business Partners, and IBM consultants planning and installing Linux on IBM Z, IBM Z family or x86 platform System administrators administering the Linux Systems If you are a customer considering LinuxONE and IBM Z family as a platform for your applications (analytics, blockchain, cloud, or other) or a pre-sales person, read those publications.
