In May 2013, Glenn Greenwald set out for Hong Kong to meet an anonymous source who claimed to have astonishing evidence of pervasive government spying and insisted on communicating only through heavily encrypted channels. That source turned out to be the 29-year-old NSA contractor Edward Snowden, and his revelations about the agency’s widespread, systemic overreach proved to be some of the most explosive and consequential news in recent history, triggering a fierce debate over national security....

In Spam Nation, investigative journalist and cybersecurity expert Brian Krebs unmasks the criminal masterminds driving some of the biggest spam and hacker operations targeting Americans and their bank accounts. Tracing the rise, fall, and alarming resurrection of the digital mafia behind the two largest spam pharmacies - and countless viruses, phishing, and spyware attacks - he delivers the first definitive narrative of the global spam problem and its threat to consumers everywhere.

Summer 2017: computer screens go blank in 150 countries. The NHS is so affected that hospitals can only take in patients for A&E. Ambulances are grounded. Computer screens turn on spontaneously and warnings appear. Employees who desperately pull the plugs are too late. Restarting is pointless; the computers are locked. And now the attackers ask each victim for money. This is hijack software. It is just one example of how vulnerable the digital world has made us.

This book is a clear and informative introduction to cryptography and data protection - subjects of considerable social and political importance. It explains what algorithms do, how they are used, the risks associated with using them, and why governments should be concerned. Important areas are highlighted, such as Stream Ciphers, block ciphers, public key algorithms, digital signatures, and applications such as e-commerce.

The Internet today connects roughly 2.7 billion people around the world, and booming interest in the "Internet of things" could result in 75 billion devices connected to the web by 2020. The myth of cyberspace as a digital utopia has long been put to rest. Governments are increasingly developing smarter ways of asserting their national authority in cyberspace in an effort to control the flow, organization, and ownership of information.

New technologies have provided both incredible convenience and new threats. The same kinds of digital networks that allow you to hail a ride using your smartphone let power grid operators control a country's electricity - and these personal, corporate, and government systems are all vulnerable. In Ukraine, unknown hackers shut off electricity to nearly 230,000 people for six hours. North Korean hackers destroyed networks at Sony Pictures in retaliation for a film that mocked Kim Jong-un.

The National Security Agency (NSA) formed a Cybersecurity Directorate in 2019 with the charge to prevent and eradicate threats to the United States’ National Security Systems and critical infrastructure, with an initial focus on the Defense Industrial Base and its service providers. Drawing on the NSA’s rich information assurance legacy, the Cybersecurity Directorate refocused to meet the demands of the present and the future. It integrated key parts of the NSA’s cybersecurity mission into a more public-facing organization determined to raise the cybersecurity bar.

As the cyber-attacks heat up and countries like China, Russia, and North Korea target the United States, its individuals, banking institutions, military, and government agencies become targets on a large scale. A recent ISACA and RSA Conference survey indicated that eight out of 10 board of directors are concerned with security. Eighty two (82) percent of organizations predict a cyber-attack is likely. It will take a giant army to fight off the new generation of cyber attackers.
