In May 2021, Jim Gosler, known as the Godfather and commander of US agencies' cyber offensive capability, said, ''Either the Intelligence Community (IC) would grow and adapt, or the Internet would eat us alive.'' Mr Gosler was speaking at his retirement only several months before the terrorist attacks of 9/11. He possibly did not realise the catalyst or the tsunami that he and his tens of thousands of US IC offensive website operatives had created and commenced. Over the last two decades, what Mr Gosler and his army of Internet keyboard warriors created would become the modus operandi for every faceless, nameless, state-sponsored or individual cybercriminal to replicate against an unwary, ill-protected, and ignorant group of executives and security professionals who knew little to nothing about the clandestine methods of infiltration and weaponisation of the Internet that the US and UK agencies led, all in the name of security. This book covers many cyber and ransomware attacks and events, including how we have gotten to the point of massive digital utilisation, particularly during the global lockdown and COVID-19 pandemic, to online spending that will see twice the monetary amount lost to cybercrime than what is spent online. There is little to no attribution, and with the IC themselves suffering cyberattacks, they are all blamed on being sophisticated ones, of course. We are witnessing the undermining of our entire way of life, our economies, and even our liberties. The IC has lots to answer for and unequivocally created the disastrous situation we are currently in. They currently have little to no answer. We need--no, we must demand--change. That change must start by ensuring the Internet and all connections to it are secure and no longer allow easy access and exfiltration for both the ICs and cybercriminals.

A real-life technological thriller about a band of eccentric misfits taking on the biggest cybersecurity threats of our time. Scattered across the world, an elite team of code crackers is working tirelessly to thwart the defining cyber scourge of our time. You've probably never heard of them. But if you work for a school, a business, a hospital, or a municipal government, or simply cherish your digital data, you may be painfully familiar with the team's sworn enemy: ransomware. Again and again, an unlikely band of misfits, mostly self-taught and often struggling to make ends meet, have outwitted the underworld of hackers who lock computer networks and demand huge payments in return for the keys. The Ransomware Hunting Team traces the adventures of these unassuming heroes and how they have used their skills to save millions of ransomware victims from paying billions of dollars to criminals.

Secure your systems better, with simple (though not always easy) practices. Plan to patch often to improve your security posture. Identify the most common software vulnerabilities, so you can avoid them when writing software. Discover cryptography - how it works, how easy it is to get wrong, and how to get it right. Configure your Windows computers securely. Defend your organization against phishing attacks with training and technical defenses. Make simple changes to harden your system against attackers. What You Need: You don't need any particular software to follow along with this book. Examples in the book describe security vulnerabilities and how to look for them. These examples will be more interesting if you have access to a code base you've worked on. Similarly, some examples describe network vulnerabilities and how to detect them. These will be more interesting with access to a network you support.

A compelling argument that the Internet of things threatens human rights and security "Sobering and important."--Financial Times, "Best Books of 2020: Technology" The Internet has leapt from human-facing display screens into the material objects all around us. In this so-called Internet of things--connecting everything from cars to cardiac monitors to home appliances--there is no longer a meaningful distinction between physical and virtual worlds. Everything is connected. The social and economic benefits are tremendous, but there is a downside: an outage in cyberspace can result not only in loss of communication but also potentially in loss of life.   Control of this infrastructure has become a proxy for political power, since countries can easily reach across borders to disrupt real-world systems. Laura DeNardis argues that the diffusion of the Internet into the physical world radically escalates governance concerns around privacy, discrimination, human safety, democracy, and national security, and she offers new cyber-policy solutions. In her discussion, she makes visible the sinews of power already embedded in our technology and explores how hidden technical governance arrangements will become the constitution of our future.

Get Started Fast with SQL! The only book you need to gain a quick working knowledge of SQL and relational databases.  Many SQL texts attempt to serve as an encyclopedic reference on SQL syntax--an approach that is often counterproductive because that information is readily available in online references published by the major database vendors. For SQL beginners, it''s more important for a book to focus on general concepts and to offer clear explanations and examples of what various SQL statements can accomplish. This is that book.   Several features make The Language of SQL unique among introductory SQL books.   First, you will not be required to download software or sit with a computer as you read the text. The intent of this book is to provide examples of SQL usage that can be understood simply by reading.   Second, topics are organized in an intuitive and logical sequence. SQL keywords are introduced one at a time, allowing you to grow your understanding as you encounter new terms and concepts.   Finally, this book covers the syntax of the latest releases of three widely used databases: Microsoft SQL Server 2019, MySQL 8.0, and Oracle 18c. Special "Database Differences" sidebars clearly show you any differences in syntax among these three databases, and instructions are included on how to obtain and install free versions of the databases.    Use SQL to retrieve data from relational databases Apply functions and calculations to data Group and summarize data in a variety of useful ways Use complex logic to retrieve only the data you need Design relational databases so that data retrieval is easy and intuitive Update data and create new tables Use spreadsheets to transform your data into meaningful displays Retrieve data from multiple tables via joins, subqueries, views, and set logic Create, modify, and execute stored procedures Install Microsoft SQL Server, MySQL, or Oracle

Unlike some operating systems, Linux doesn't try to hide the important bits from you—it gives you full control of your computer.
