There were eight mega breaches in 2013, compared with only one in 2012. - Viruses and Malware. Some security experts estimate there are more than 250,000 new malware variants detected daily and more than 30,000 websites exploited daily. These numbers are staggering. - Email Security. Learn how to reduce the amount of SPAM that makes it to your inbox. Improve your email security habits and discover better ways to communicate safely and with privacy. - Internet and Browsing Security. You cannot afford to leave the security of your sensitive information up to your ISP. It is actually easy to apply a layered approach to security and minimize your risk. Learn about your options; then pick and choose what works for you and your situation.

If a network is not secure, how valuable is it? Introduction to Computer Networks and Cybersecurity takes an integrated approach to networking and cybersecurity, highlighting the interconnections so that you quickly understand the complex design issues in modern networks. This full-color book uses a wealth of examples and illustrations to effective

So whether you're a cyber security professional, hobbyist, business manager, or student aspiring to becoming an ethical hacker or just want to learn more about the cyber security aspect of the IT industry, then this book is definitely for you. What You Will Learn Use SET to clone webpages including the login page Understand the concept of Wi-Fi cracking and use PCAP file to obtain passwords Attack using a USB as payload injector Familiarize yourself with the process of trojan attacks Use Shodan to identify honeypots, rogue access points, vulnerable webcams, and other exploits found in the database Explore various tools for wireless penetration testing and auditing Create an evil twin to intercept network traffic Identify human patterns in networks attacks In Detail Computer networks are increasing at an exponential rate and the most challenging factor organisations are currently facing is network security. Breaching a network is not considered an ingenious effort anymore, so it is very important to gain expertise in securing your network. The book begins by showing you how to identify malicious network behaviour and improve your wireless security. We will teach you what network sniffing is, the various tools associated with it, and how to scan for vulnerable wireless networks. Then we'll show you how attackers hide the payloads and bypass the victim's antivirus. Furthermore, we'll teach you how to spoof IP / MAC address and perform an SQL injection attack and prevent it on your website. We will create an evil twin and demonstrate how to intercept network traffic. Later, you will get familiar with Shodan and Intrusion Detection and will explore the features and tools associated with it. Toward the end, we cover tools such as Yardstick, Ubertooth, Wifi Pineapple, and Alfa used for wireless penetration testing and auditing. This book will show the tools and platform to ethically hack your own network whether it is for your business or for your personal home Wi-Fi. Style and approach This mastering-level guide is for all the security professionals who are eagerly waiting to master network security skills and protecting their organization with ease. It contains practical scenarios on various network security attacks and will teach you how to avert these attacks.

For some small businesses, the security of their information, systems, and networks might not be a high priority, but for their customers, employees, and trading partners it is very important. The size of a small business varies by type of business, but typically is a business or organization with up to 500 employees. In the U.S., the number of small businesses totals to over 95% of all businesses. The small business community produces around 50% of our nation¿s GNP and creates around 50% of all new jobs in our country. Small businesses, therefore, are a very important part of our nation¿s economy. This report will assist small business management to understand how to provide basic security for their information, systems, and networks. Illustrations.

Cybersecurity for Beginners is an engaging introduction to the field of cybersecurity. You'll learn how attackers operate, as well as how to defend yourself and organizations against online attacks. You don’t need a technical background to understand core cybersecurity concepts and their practical applications – all you need is this book. It covers all the important stuff and leaves out the jargon, giving you a broad view of how specific attacks work and common methods used by online adversaries, as well as the controls and strategies you can use to defend against them. Each chapter tackles a new topic from the ground up, such as malware or social engineering, with easy-to-grasp explanations of the technology at play and relatable, real-world examples. Hands-on exercises then turn the conceptual knowledge you’ve gained into cyber-savvy skills that will make you safer at work and at home. You’ll explore various types of authentication (and how they can be broken), ways to prevent infections from different types of malware, like worms and viruses, and methods for protecting your cloud accounts from adversaries who target web apps. You’ll also learn how to: • Use command-line tools to see information about your computer and network • Analyze email headers to detect phishing attempts • Open potentially malicious documents in a sandbox to safely see what they do • Set up your operating system accounts, firewalls, and router to protect your network • Perform a SQL injection attack by targeting an intentionally vulnerable website • Encrypt and hash your files In addition, you’ll get an inside look at the roles and responsibilities of security professionals, see how an attack works from a cybercriminal’s viewpoint, and get first-hand experience implementing sophisticated cybersecurity measures on your own devices.

The perimeter defenses guarding your network perhaps are not as secure as you think. Hosts behind the firewall have no defenses of their own, so when a host in the "trusted" zone is breached, access to your data center is not far behind. That’s an all-too-familiar scenario today. With this practical book, you’ll learn the principles behind zero trust architecture, along with details necessary to implement it. The Zero Trust Model treats all hosts as if they’re internet-facing, and considers the entire network to be compromised and hostile. By taking this approach, you’ll focus on building strong authentication, authorization, and encryption throughout, while providing compartmentalized access and better operational agility. Understand how perimeter-based defenses have evolved to become the broken model we use today Explore two case studies of zero trust in production networks on the client side (Google) and on the server side (PagerDuty) Get example configuration for open source tools that you can use to build a zero trust network Learn how to migrate from a perimeter-based network to a zero trust network in production

A practical handbook for network adminstrators who need to develop and implement security assessment programs, exploring a variety of offensive technologies, explaining how to design and deploy networks that are immune to offensive tools and scripts, and detailing an efficient testing model.
