Hewlett Packard Enterprise (HPE) Service Virtualization (SV)Jeffrey Nunn
Service Virtualization is an HPE branded solution that helps simulate and emulate the behavior of specific components in heterogeneous component-based applications such as API-driven apps, ERP apps, cloud-based apps, and web services/service-oriented architectures (SOA).
Value Proposition
Empowers developers and testers to easily automate, predict, accelerate and scale their application testing and delivery through virtualization and simulation of dependent components and services that are either off limits, unavailable, inaccessible, or with costly fees to access.
Quantitative Risk Analysis Workshop - focused on working with business risk and factoring in cyber elements, and how to optimize the application of controls for the most effective risk management.
This document discusses DevSecOps at Cimpress, an online printing company. It outlines some of the challenges of their worldwide and decentralized operations with varying technology stacks. Their approach involves threat modeling to identify threats, assets, and controls. They create security assertions based on the threat model and assure test case coverage. The focus is on integrating security into development in a way that is not burdensome to developers. The expected deliverables include automated unit test coverage and tool scans to address the threat model.
Risk metric frameworks cover most of the elements that organizations deal with from an operational perspective. We have identified a gap in those, in which social media activities are not represented well (albeit being the highest growing attack vector). In this talk we’ll present a social media risk metric framework that allows organizations to measure and track both individuals as well as 3rd party entities risk to the organization.

This document discusses cyber security risks in the financial and healthcare industries and their impact on homeland security. It covers three parts: examples of information disclosure vulnerabilities in access points; connecting these vulnerabilities to critical infrastructure protection and homeland security; and arguing that an asset-centric rather than product-centric approach is needed to address industry-specific security challenges.
The document discusses the roles and techniques of red teams and blue teams, with the red team focusing on simulating real threats through activities like social engineering and identifying vulnerabilities, while the blue team aims to assess risks, minimize damage from attacks, and apply lessons learned to strengthen processes, people, and technology. It provides examples of tactics for each team and emphasizes the importance of collaboration between red and blue teams to continuously improve an organization's security.
"Cyber" security - all good, no need to worry?Iftach Ian Amit
This document discusses cyber security risks and incidents over time. It notes that 52% of all incidents are from businesses, with government, medical, and education each accounting for around 15-20% of incidents. The majority (57%) of incidents are caused by outside actors, while 20% are from insider threats and 10% are accidental insider incidents. The number of reported data loss incidents has increased significantly over time from just over 100 in 2004 to over 1600 in 2013. The document advocates returning to basic risk management practices, including prioritizing remediation based on risk, impact, costs, and addressing the most critical gaps in assets, processes, technologies and threats based on priority. It warns against overspending on products and focusing
This document discusses the importance of application logs for security purposes. It notes that while network, system and other logs have improved, application logs are still often lacking crucial context about user actions and application state. To effectively investigate issues, security analysts need a unified view of all log data, including details applications have about user sessions, access and functionality used. The document urges application developers to make more of this type of contextual log data available to defenders to help connect dots between different system components and entities.
Derbycon 2013 - Seeing Red in Your Future?
This talk is designed to complement the “Fifty Shades of Red” talk tomorrow, and provide context for organizations who either think about engaging in a red team test, or have been doing red teaming and want to see more value out of it. In this talk we’ll cover some of the basic elements of what red teaming is, and specifically how it benefits an organization engaging in such a practice. Red teaming by itself is a high-interaction test. Unlike many other tests (namely penetration testing, compliance engagements, vulnerability assessments and other IT related practices), red team is not limited to the technical scope of the organization’s security infrastructure. As such, it is imperative to be able to extract as much value out of a red team engagement as possible, and see return on that investment in as many different areas of the organization as possible. Based on years of experience in conducting red team tests, training and helping organizations improve their security through red teaming, these insights will be applicable to everyone who is seeing red in their future (and you all should in order to really address security in an organization that has people working in it and not just machines).
Hacking involves a single target and shallow attacks using common tools and techniques, motivated by financial or political goals. Cyber attacks are part of cyber warfare involving strategic targets across physical, social, intelligence and electronic domains using custom tools in a coordinated campaign. Cyber defenses require a strategic defense in depth approach across all domains with awareness training, unlike typical IT security products. Hacking is an individual battle while cyber attacks are part of a larger warfare strategy.
This document discusses best practices for securely storing passwords. It notes that passwords are often stored insecurely, such as in plain text. To securely store passwords, it recommends encrypting them using cryptographic hash functions with salts. Specifically, it advises using functions such as SHA-2, bcrypt, and scrypt, which can include salts and be slowed down through key stretching to make passwords very difficult to hack or crack. Following these guidelines helps protect users and companies by securing password data.
This document provides an introduction to bitcoin, including what it is, how it works, advantages, disadvantages, weaknesses, history, data, mining process over time, physical representations, and future possibilities. Bitcoin is described as a decentralized digital currency based on cryptography, without a central authority. Transactions are confirmed by miners who are rewarded with new bitcoins. Key aspects covered include how users can send and receive bitcoins, security issues, increasing difficulty of mining over time, and the currency's value and adoption over its history.
The document discusses strategies for maximizing home-field advantage in cybersecurity defense. It argues that defenders should flip the perspective of red team attackers by mapping assets and security issues, correlating internal and external threat data over time, and taking proactive measures like counterintelligence operations. Examples given include infiltrating hacker communities to booby-trap tools and using attackers' own tools against them. The presentation calls on vendors to develop integrative security products and defenders to own their security data and intelligence in order to focus defenses on real risks rather than compliance.

The document appears to be a presentation about infiltration techniques for cyber attacks. It discusses exploiting technical vulnerabilities like web, email and remote access software. It also covers gaining access through social engineering, like sending malicious links and files to trick users. The presentation emphasizes targeting individuals within an organization and using common tools like ZeuS or SpyEye malware to acquire sensitive data from infected systems.
The document discusses mesh networks, which are wireless networks formed by connecting nodes without centralized administration. It describes the topology and attributes of mesh networks, including that they are self-organizing, self-healing, and scalable. It then provides examples of several existing mesh networks around the world and discusses some of the technical and community challenges in building mesh networks.
HTML5 introduces new features that can be exploited if not implemented securely. Storage mechanisms like local storage, session storage, and IndexedDB can be used to steal sensitive user data if not set with the proper security flags. Cross-origin resource sharing and cross-document messaging allow communication between domains but need controls to prevent CSRF and information disclosure. New HTML5 features provide opportunities for old attacks like XSS through new vectors like autofocus. Developers must implement security best practices to prevent exploitation of HTML5 capabilities.

הבעיה -
דגמנו מידע וקיבלנו "גל מידע" מסויים. אך גל זה לא בהכרח מורכב
מתדרים אותם אנו מסוגלים להעביר.
הסיבה לכך יכולה להיות תכונות התווך )בין השאר, הפרעות חיצוניות(, או
תכונות ציוד השידור.
לדומה, תחום הקול האנושי המועבר בטלפון הוא בין 3.0 ל4- .kHzאם
היינו רוצים לשדר גל אלקטרומגנטי בתדרים אלו היינו צריכים להשתמש

הפתרון -
נייצג את גל המידע אותו דגמנו באמצעות שינויים אשר נבצע בגל אחר,
אותו קל לנו להעביר.
● הגל המקורי נקרא "גל המידע".
● הגל אשר בחרנו להעביר באמצעותו את השידור נקרא "גל נושא".
● הגל שנוצר לנו מתהליך השינוי נקרא "גל מאופנן".
