Cyber security is one of the most critical problems faced by enterprises, government organizations, education institutes, small and medium scale businesses, and medical institutions today. Creating a cyber security posture through proper cyber security architecture, deployment of cyber defense tools, and building a security operation center are critical for all such organizations given the preponderance of cyber threats. However, cyber defense tools are expensive, and many small and medium-scale business houses cannot procure these tools within their budgets. Even those business houses that manage to procure them cannot use them effectively because of the lack of human resources and the knowledge of the standard enterprise security architecture. In 2020, the C3i Center at the Indian Institute of Technology Kanpur developed a professional certification course where IT professionals from various organizations go through rigorous six-month long training in cyber defense. During their training, groups within the cohort collaborate on team projects to develop cybersecurity solutions for problems such as malware analysis, threat intelligence collection, endpoint detection and protection, network intrusion detection, developing security incidents, event management systems, etc. All these projects leverage open-source tools, and code from various sources, and hence can be also constructed by others if the recipe to construct such tools is known. It is therefore beneficial if we put these recipes out in the form of book chapters such that small and medium scale businesses can create these tools based on open-source components, easily following the content of the chapters. In 2021, we published the first volume of this series based on the projects done by cohort 1 of the course. This volume, second in the series has new recipes and tool development expertise based on the projects done by cohort 3 of this training program. This volume consists of nine chapters that describe experience and know-how of projects in malware analysis, web application security, intrusion detection system, and honeypot in sufficient detail so they can be recreated by anyone looking to develop home grown solutions to defend themselves from cyber-attacks.

Disability is the functional inability of an individual to perform any activity in the manner or within the range considered `normal'. These are relatively permanent conditions and in most cases can be tackled only by early intervention and long-term therapy.

The accurate diagnosis of a child with a disorder is an important prelude to planning the right programme for intervention and rehabilitation. The book is intended for early identification of such developmental problems in infants and pre-school children. It covers a wide range of impairments, disabilities and handicaps commonly seen in young children. It is meant to enable parents to appreciate their manifestations, prevalence and characteristics.

The book recognizes the importance of home-based programmes and contains lists of more than 400 activities as non-formal curriculum for young children. It carries broad guidelines on how to train children for these activities at home or pre-school settings. This book will be of great help to parents and trainers who are searching for suggestions from professionals on not only what training to impart to these children, but also how to train them at low cost and within their home settings.

The book also serves as a reference guide for students of disability management or rehabilitation sciences. All teaching objectives and items included in this practical guide are empirically validated and located along a hierarchical scale of developmental difficulty. They are worded in behavioural terms so that trainers can readily start working on the given goals for behaviour change in the children.

This book is meant for students and professionals in the field of rehabilitation services for disabled, general or special education programmes, parents of pre-school children, those who run play schools or crèches, non-formal educators, speech therapists, occupational therapists, physiotherapists and paediatricians.
