RESILIA™ Foundation: In-House Training AXELOS RESILIA™: Cyber Resilience Best Practice is designed to help commercial and government organizations around the world prevent, detect, and correct any impact cyber attacks will have on the information required to do business. Adding RESILIA to the existing AXELOS global best practice portfolio, including ITIL® and PRINCE2®, brings a common cyber resilience best practice for security, IT service management, and business. Active cyber resilience is achieved through people, process, and technology. The RESILIA™ Foundation course starts with the purpose, key terms, the distinction between resilience and security, and the benefits of implementing cyber resilience. It introduces risk management and the key activities needed to address risks and opportunities. Further, it explains the relevance of common management standards and best practice frameworks to achieve cyber resilience. Subsequently, it identifies the cyber resilience processes, the associated control objectives, interactions, and activities that should be aligned with corresponding ITSM activities. In the final part of the course, it describes the segregation of duties and dual controls related to cyber resilience roles and responsibilities. What you will Learn At the end of this course, you will be able to: Demonstrate your knowledge of the purpose, benefits, and key terms of cyber resilience Demonstrate your knowledge of the risk management and the key activities needed to address risks and opportunities Demonstrate your knowledge of the purpose of a management system and how best practices and standards can contribute Demonstrate your knowledge of the cyber resilience strategy, the associated control objectives, and their interactions with ITSM activities Demonstrate your knowledge of cyber resilience design, the associated control objectives, and their interactions with ITSM activities Demonstrate your knowledge of cyber resilience transition, the associated control objectives, and their interactions with ITSM activities Demonstrate your knowledge of cyber resilience operation, the associated control objectives, and their interactions with ITSM activities Demonstrate your knowledge of cyber resilience continual improvement, the associated control objectives, and their interactions with ITSM activities Demonstrate your knowledge of the purpose and benefits of segregation of duties and dual controls Course Introduction Course Learning Objectives Course Agenda Activities Course Book Structure RESILIA Certification Introduction to Cyber Resilience What is Cyber Resilience?

This course bundle is ideal for anyone looking to establish their Cisco networking career. It consists of one Cisco Certified Network Associate (CCNA) certification, one Cisco Certified DevNet Associate (CCDA) certification, and four Cisco Certified Networking Professional (CCNP) certifications. Although there are no formal prerequisites to enrol on the CCNA, CCDA, or CCNP certification courses and sit the exams, learners should have a good foundation knowledge in networking. The newly retooled CCNA covers a breadth of topics, including: Network fundamentals Network access IP connectivity IP services Security fundamentals Automation and programmability Achieving CCNA certification is the first step in preparing for a career in networking technologies. To earn your CCNA certification, you only need to pass one exam – which covers a broad range of fundamentals for IT careers, based on the latest networking technologies. The Cisco Certified DevNet Associate certification validates your skills and knowledge in understanding and using APIs, Cisco platforms and development, application development and security, and infrastructure and automation. Ideally, DevNet Associates candidates also have one or more years of experience with software development including Python programming. The CCNP is the next level from the CCNA and CCDA. As with the CCNA, there are no formal prerequisites to enrol on the CCNP certification course and sit for the exams. Learners taking a CCNP course generally have an in-depth knowledge of networking, as well as a good understanding of Cisco technologies. The typical certification path for most learners would begin with either the CCDA or CCNA, then progress onto the CCNP. Learners need to pass two exams (one core exam and one concentration exam) in order to gain one CCNP certification. This course bundle includes the core exam and three concentration exams. Once a learner has passed the core exam, they can choose to specialise in one or all three of the CCNP concentration areas listed in this course. The core exam’s focus is based around implementing and operating Cisco enterprise network core technologies.
