This document discusses how to hack wireless networks and how to prevent it. It begins with a disclaimer from the speaker that he works for Aruba Networks and has no time to actually hack networks. It then asks if people see wireless as less secure than wired, pointing out that wireless can be more secure if implemented correctly. Finally, it questions if wired networks authenticate all users, encrypt all traffic, and control access based on identity, implying wireless can do all these things too if set up properly.
The following is a smart grid security presentation I developed for my fellow task force members on NERC's 2010 Smart Grid Task Force. The charts included are very helpful in understanding at a glance, where the risks and threats to smart grid reliability and security lie. In the end though it is the 'human factor' that is most important to keep in mind in risk mitigation.
This presentation addresses the unique challenges of securing Smart Meters and SCADA devices within the power grid. The Revere Security Hummingbird cipher is introduced as a solution to the problem of securing microprocessors below 32-bit.
Cyber Crime http://bit.ly/2Ygftys
Cybercrime is defined as a crime in which a computer is the object of the crime (hacking, phishing, spamming) or is used as a tool to commit an offense (child pornography, hate crimes). Cybercriminals may use computer technology to access personal information, business trade secrets or use the internet for exploitative or malicious purposes. Criminals can also use computers for communication and document or data storage. Criminals who perform these illegal activities are often referred to as hackers.

Network Vulnerabilities Assessment and Recommendations
Introduction
Today network security is a big concern for many organizations. Today, one of the biggest security challenges is the level of sophistication of attacks. Attackers are using common internet tools and protocols to carry out attacks [1]. This makes it difficult to distinguish between an attack and a legitimate traffic. Vulnerability is caused by insufficient protection of sensitive data and network and an attacker can exploit the weakness to access sensitive information [2].
This report is an analysis of network vulnerability of a small accounting firm. The firm has 21 workers, including the owner. Out of the 21, 10 are accountants, 3 are administrative assistants, 1 vice president, 1 financial manager, 2 interns, and 1 manager, who is also the owner. The company has 20 computers and two multi-purpose printers. The manager uses his personal iPad to read and responds to emails. The firm’s network is simple and all computers are connected to the internet via a wireless NETGEAR MT814 device.
A sketch of the current network setup
The Identified Vulnerabilities
Router: Wireless routers can be an ideal target for network hackers. The accounting firm’s network uses a NETGEAR MR814 router that is connected to a Motorola SB3100 cable modem. The router has the following vulnerabilities:
· Denial of service (DoS) attack: Happens when attackers bombard a target resource with unauthorized requests, which makes the resource to become unavailable to the authorized users. Comment by Roger Seeholzer: Source? Comment by Edwige Kouassi:
· Network injections: In this case, an attacker can inject networking re-configuration codes, which might affect the router and other intelligent networking devices. Comment by Roger Seeholzer: Source
· Default passwords or weak passwords: Leaving the default password of the router unchanged provides a perfect point of network infiltration. Similarly, weak password for the firm’s router can be risky and vulnerable to hackers. Comment by Roger Seeholzer: Was it found or are you just saying this?
Access Points:
· The firm’s wireless network is not limited or controlled to have physical boundary, which would prevent accidental associations.
· Rogue access points: Comment by Roger Seeholzer: What about this? Why have you listed rogue access points?
· Eavesdropping: Hackers can try to listen and to collect data between nodes in the wireless network. Comment by Roger Seeholzer: How is this done? Did you find this to be happening here?
· Mac spoofing: Hackers can listen to the traffic of the network and try to identify the MAC addresses of privileged workstations. Comment by Roger Seeholzer: Did you find any spoofed addresses on the wireless network (while reviewing router logs)?
· Default shared keys: Comment by Roger Seeholzer: What is thius here for? How do ...

Testing IoT Security shouldn't fear you if you have got a hacker mindset - By...Santhosh Tuppad
Most of us have fear when we have spent so much of time in doing something and all of a sudden we are made to embrace a new change which could be in terms of technology. Recently, IoT, AI, ML and Automation have been great subjects and are made to be believed by testers as “Problem Solvers” for “Testing” problem which isn’t really true. They do add value, but let’s not compare them with testing because they are elements of testing while Testing still remains a profession which requires intelligence and is backed by Science.
In this talk, Santhosh Tuppad will try to help the testers to kick-out the fear and embrace the new technologies and learn them by helping them to understand Mindset concept and built their mindset very well. He shall also speak about IoT Security Elements and then relate them to daily life and and current web / mobile hacking. In short, “Once a tester has a mindset of Security or Hacking, it’s much easier to embrace new technologies or domains or software as most of the ideas from web/mobile hacking or life are relevant.
This talk relates very much too, Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime. ATTRIBUTION: Chinese proverb

How companies approach this type of transition is critical to their success. How should organizations prepare? Why is it important to understand the dependencies within their line of business applications when migrating to a virtual environment? How can they manage the physical and virtual worlds as single environment? How can organizations verify that their systems conform to corporate and government oversight requirements in a way that meets their needs without becoming burdensome? Get the answers to these questions and more.
How taking a strategic approach to WAN optimization supports application deli...digitallibrary
Enterprises and service providers tend to offer WAN optimization as a tactical �quick fix� to performance problems in certain parts of the network. Taking a more strategic approach to WAN optimization can yield benefits across the enterprise that are not limited to fixing short-term performance and bandwidth challenges.
File Area Network (FAN) is a term used to describe a more formal approach to architecting a heterogeneous, enterprise-wide, service-oriented file storage infrastructure. FAN enhances standard network and storage infrastructure with technology that provides centralized, heterogeneous, and enterprise-wide network file management and control. This technology includes a decoupling or virtualization layer that separates logical file access from physical file locations and a variety of value-added file services.
Virtualization is becoming the IT infrastructure of the enterprise�s datacenter. This presentation discusses the advantages of utilizing this infrastructure for WAN optimization deployments. Learn the benefits of virtualization, WAN optimization deployment options, virtualization and WAN optimization in the remote branch and VDI and WAN optimization.
