Privileged Attack Vectors : Building Effective Cyber-Defense Strategies to Protect Organizations
See how privileges, insecure passwords, administrative rights, and remote access can be combined as an attack vector to breach any organization.Cyber attacks continue to increase in volume and sophistication.It is not a matter of if, but when, your organization will be breached.Threat actors target the path of least resistance: users and their privileges. In decades past, an entire enterprise might be sufficiently managed through just a handful of credentials.Today’s environmental complexity has seen an explosion of privileged credentials for many different account types such as domain and local administrators, operating systems (Windows, Unix, Linux, macOS, etc.), directory services, databases, applications, cloud instances, networking hardware, Internet of Things (IoT), social media, and so many more.When unmanaged, these privileged credentials pose a significant threat from external hackers and insider threats.We are experiencing an expanding universe of privileged accounts almost everywhere. There is no one solution or strategy to provide the protection you need against all vectors and stages of an attack. And while some new and innovative products will help protect against or detect against a privilege attack, they are not guaranteed to stop 100% of malicious activity.The volume and frequency of privilege-based attacks continues to increase and test the limits of existing security controls and solution implementations. Privileged Attack Vectors details the risks associated with poor privilege management, the techniques that threat actors leverage, and the defensive measures that organizations should adopt to protect against an incident, protect against lateral movement, and improve the ability to detect malicious activity due to the inappropriate usage of privileged credentials.This revised and expanded second edition covers new attack vectors, has updated definitions for privileged access management (PAM), new strategies for defense, tested empirical steps for a successful implementation, and includes new disciplines for least privilege endpoint management and privileged remote access. What You Will LearnKnow how identities, accounts, credentials, passwords, and exploits can be leveraged to escalate privileges during an attack Implement defensive and monitoring strategies to mitigate privilege threats and risk Understand a 10-step universal privilege management implementation plan to guide you through a successful privilege access management journeyDevelop a comprehensive model for documenting risk, compliance, and reporting based on privilege session activity Who This Book Is For Security management professionals, new security professionals, and auditors looking to understand and solve privilege access management problems

What are vectors?
Vectors are mathematical objects that have both magnitude and direction. They are often represented as arrows in space, with the length of the arrow representing the magnitude and the direction indicating the direction. Vectors are used in various fields such as physics, engineering, and computer science to represent quantities like velocity, force, and displacement. They can be added, subtracted, and multiplied by scalars to perform various operations.
-
How do vectors intersect?
Vectors intersect when they share a common point in space. This point is known as the point of intersection. To determine if two vectors intersect, we can set their parametric equations equal to each other and solve for the variables. If the resulting values satisfy both equations, then the vectors intersect at that point. If the vectors are parallel or skew (non-intersecting and non-parallel), they do not intersect.
-
What are collinear vectors?
Collinear vectors are vectors that lie on the same straight line or are parallel to each other. This means that they have the same direction or are in the opposite direction of each other. Collinear vectors can be scaled versions of each other, meaning one vector is a multiple of the other. In other words, collinear vectors have the same or opposite direction and are located on the same line or parallel lines.
-
How are vectors determined?
Vectors are determined by both magnitude and direction. The magnitude of a vector represents the length or size of the vector, while the direction indicates the orientation of the vector in space. Vectors can be represented graphically as arrows, with the length of the arrow representing the magnitude and the direction of the arrow indicating the direction. Mathematically, vectors can be described using coordinates or components in a specific coordinate system.

Geometric Multiplication of Vectors : An Introduction to Geometric Algebra in Physics
This book enables the reader to discover elementary concepts of geometric algebra and its applications with lucid and direct explanations.Why would one want to explore geometric algebra? What if there existed a universal mathematical language that allowed one: to make rotations in any dimension with simple formulas, to see spinors or the Pauli matrices and their products, to solve problems of the special theory of relativity in three-dimensional Euclidean space, to formulate quantum mechanics without the imaginary unit, to easily solve difficult problems of electromagnetism, to treat the Kepler problem with the formulas for a harmonic oscillator, to eliminate unintuitive matrices and tensors, to unite many branches of mathematical physics?What if it were possible to use that same framework to generalize the complex numbers or fractals to any dimension, to play with geometry on a computer, as well as to make calculations in robotics, ray-tracing and brain science?In addition, what if such a language provided a clear, geometric interpretation of mathematical objects, even for the imaginary unit in quantum mechanics?Such a mathematical language exists and it is called geometric algebra.High school students have the potential to explore it, and undergraduate students can master it.The universality, the clear geometric interpretation, the power of generalizations to any dimension, the new insights into known theories, and the possibility of computer implementations make geometric algebra a thrilling field to unearth.

Framing Animals as Epidemic Villains : Histories of Non-Human Disease Vectors
This book takes a historical and anthropological approach to understanding how non-human hosts and vectors of diseases are understood, at a time when emerging infectious diseases are one of the central concerns of global health.The volume critically examines the ways in which animals have come to be framed as ‘epidemic villains’ since the turn of the nineteenth century.Providing epistemological and social histories of non-human epidemic blame, as well as ethnographic perspectives on its recent manifestations, the essays explore this cornerstone of modern epidemiology and public health alongside its continuing importance in today’s world.Covering diverse regions, the book argues that framing animals as spreaders and reservoirs of infectious diseases – from plague to rabies to Ebola – is an integral aspect not only to scientific breakthroughs but also to the ideological and biopolitical apparatus of modern medicine.As the first book to consider the impact of the image of non-humandisease hosts and vectors on medicine and public health, it offers a major contribution to our understanding of human-animal interaction under the shadow of global epidemic threat.

Are the vectors collinear?
To determine if the vectors are collinear, we need to check if one vector is a scalar multiple of the other. If the vectors are collinear, then one vector can be obtained by multiplying the other vector by a scalar. If the vectors are not collinear, then they will not be scalar multiples of each other.

What are basis vectors?
Basis vectors are a set of linearly independent vectors that can be used to represent any vector in a given vector space through linear combinations. They form the building blocks for expressing any vector in the space. In a 2D space, the basis vectors are typically denoted as i and j, while in a 3D space, they are denoted as i, j, and k. Basis vectors are essential for understanding and working with vector spaces in linear algebra and are fundamental to many mathematical and physical concepts.
-
What are parallel vectors?
Parallel vectors are vectors that have the same or opposite direction, but may have different magnitudes. In other words, if two vectors are parallel, they either point in the same direction or in exactly opposite directions. This means that one vector is a scalar multiple of the other. For example, if vector A is parallel to vector B, then vector A = k * vector B, where k is a scalar.
-
What are lattice vectors?
Lattice vectors are a set of vectors that define the periodic structure of a crystal lattice. They represent the translation symmetry of the lattice and can be used to generate all the points in the lattice by adding integer multiples of the lattice vectors to a reference point. In a 3D crystal lattice, there are typically three lattice vectors that are linearly independent and form the basis for the lattice. The lattice vectors are essential for describing the crystal structure and understanding the physical properties of materials.
