TL;DR: This chapter introduces key modes of operation for symmetric cryptosystems, Electronic Code Book (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB), and Counter Mode (CTR) and ensures that the safety of personnel is a key consideration when considering physical and environmental security.
Abstract: Domain 3: Security Engineering, represents a large and complex technical domain. The chapter presents key cryptographic concepts of authentication and non-repudiation in addition to confidentiality and integrity, which are concepts presented in many of the domains. Beyond the foundational operations such as substitution and permutation and types of cryptosystems, symmetric, asymmetric, and hashing, this chapter also introduces key modes of operation for symmetric cryptosystems, Electronic Code Book (ECB), Cipher Block Chaining (CBC), Cipher Feedback (CFB), Output Feedback (OFB), and Counter Mode (CTR). The goal of the domain’s final section is to ensure that the safety of personnel is a key consideration when considering physical and environmental security. To ensure this safety requires an understanding of common issues that could negatively impact personnel’s safety, such as fire, smoke, flood, and toxins, with particular emphasis on smoke and fire detection and suppression. Physical security is the other main focus of this chapter and attention is given to physical access control matters including fences, gates, lights, cameras, locks, mantraps, and guards.
TL;DR: The article relates that while airports in Canada have implemented automated “mantrap” technology into their airport access control systems and the new Restricted Area Identification Card (RAIC), airports in the U.S. are reportedly not required to staff doors leading to restricted areas.
Abstract: This article focuses on the problem of “piggybacking” and “tailgating” at airport security checkpoints. Transport Canada is addressing this issue of unauthorized entry by requiring that all doors leading to restricted terminal areas must be staffed by inspection guards. The article relates that while airports in Canada have implemented automated “mantrap” technology into their airport access control systems and the new Restricted Area Identification Card (RAIC), airports in the U.S. are reportedly not required to staff doors leading to restricted areas. Rather than addressing access control, U.S. airports have put their attention more on passenger and luggage screening. The article gives an overview of the technology and operations of the automated security systems, as well as the costs involved in their application.
TL;DR: This chapter covers Domain 10 of the CISSP, Physical (Environmental) Security and attention is given to physical access control matters including fences, gates, lights, cameras, locks, mantraps, and guards.
