It further demonstrates audit techniques and collecting evidence to write important documentation by following the ISO 27001 standards.The book:Elaborates on the application of confidentiality, integrity, and availability (CIA) in the area of audit planning and preparationCovers topics such as managing business assets, agreements on how to deal with business assets, and media handlingDemonstrates audit techniques and collects evidence to write the important documentation by following the ISO 27001 standardsExplains how the organization’s assets are managed by asset management, and access control policiesPresents seven case studies

This textbook offers the knowledge and the mathematical background or techniques that are required to implement encryption/decryption algorithms or security techniques. It also provides the information on the cryptography and a cryptosystem used by organizations and applications to protect their data and users can explore classical and modern cryptography. The first two chapters are dedicated to the basics of cryptography and emphasize on modern cryptography concepts and algorithms. Cryptography terminologies such as encryption, decryption, cryptology, cryptanalysis and keys and key types included at the beginning of this textbook . The subsequent chapters cover basic phenomenon of symmetric and asymmetric cryptography with examples including the function of symmetric key encryption of websites and asymmetric key use cases. This would include security measures for websites, emails, and other types of encryptions that demand key exchange over a public network.Cryptography algorithms (Caesar cipher, Hill cipher, Playfair cipher, Vigenere cipher, DES, AES, IDEA, TEA, CAST, etc.) which are varies on algorithmic criteria like- scalability, flexibility, architecture, security, limitations in terms of attacks of adversary. They are the core consideration on which all algorithms differs and applicable as per application environment. The modern cryptography starts from invent of RSA (Rivest-Shamir-Adleman) which is an asymmetric key algorithm based on prime numbers. Nowadays it is enabled with email and digital transaction over the Internet. This textbook covers Chinese remainder theorem, Legendre, Jacobi symbol, Rabin cryptosystem, generalized ElGamal public key cryptosystem, key management, digital signatures, message authentication, differential cryptanalysis, linear cryptanalysis, time-memory trade-off attack, network security, cloud security, blockchain, bitcoin, etc. as well as accepted phenomenon under modern cryptograph. Advanced level students will find this textbook essential for course work and independent study. Computer scientists and engineers and researchers working within these related fields will also find this textbook useful.

This book is designed with the goal of providing a comprehensive understanding of the structure of a computer and its operations, the RTL and Micro-level operations and control in a computer, the concepts of I/O and memory organization and operating systems. Able to visualize the organization of different blocks in a computer, able to use micro-level operations to control different units in a computer, able to use Operating systems in a computer in a single textbook. In addition, the book contains an entire chapter on computer organization and operating systems. This book covers both the fundamentals of computer organization and operating systems. Separate chapters are allocated to cover design methodologies of simple and complex combinational and sequential circuits. The book covers Basic Structure of Computers, Register Transfer Language and Micro Operations, Micro Programmed Control, The Memory System, Input-Output Organization, Operating Systems Overview, memory organization, Principles of Deadlock, File System Interface and File System Implementation.

Computer forensics is the process of methodically examining computer media (harddisks, diskettes, tapes, etc.) for evidence. In other words, computer forensics is thecollection, preservation, analysis, and presentation of computer-related evidence. Computer forensics also referred to as computer forensic analysis, electronic discovery, electronic evidence discovery, digital discovery, data recovery, data discovery, computeranalysis, and computer examination. Computer evidence can be useful in criminal cases, civil disputes, and human resources/employment proceedings

This book presents a new trust based light weight authentication routing protocol. In this approach, the secure path is established based on the node‟s trust value and this trust is measured based on packet success ratio (PSR). If the trust value of any node is below threshold value, then it is authenticated using the secret sharing technique. This authentication technique enhances the reliability, redundancy and network lifetime.To achieve data confidentiality and integrity a new secure multipath routing and data transmission protocol presented. This protocol accomplished a digitally signed Route Request (RREQ) at every source node to find a secure route towards the destination node. The choosing of the next node in every path is based on these signatures only.A Certificate Authority Distribution and Trust based Threshold Revocation method is developed. Based on the Certificate distribution and threshold revocation, the nodes which are malicious can be detected by its neighbour nodes.The officials of the certificate distribute the secret key to all nodes. Following, a threshold revocation technique based on confidence is calculated. Here the nodes of misbehavior are removed.

This book presents the subject of Compiler Design in a way that's understandable to a programmer, rather than a mathematician. Our basic premise is that the best way to learn how to write a compiler is to look at one in depth; the best way to understand the theory is to build tools that use that theory for practical ends. So, this book is built around working code that provides immediate practical examples of how given theories are applied. We make no claims that the code presented here is the only (or the best) implementation of the concepts presented. We've found, however, that looking at an implementation-at any implementation--can be a very useful adjunct to understanding the theory, and the reader is well able to adapt the concepts presented here to alternate implementations.
