      While assembling a complete list of every advancement that the world has seen in recent decades and how such changes impact cybersecurity in effectively impossible, we can examine several key development area and their impacts on the ever-evolving nature of cybersecurity: technological changes, economic model shifts, and outsourcing.

      Technological changes

      Technological changes tremendously impact cybersecurity. New risks come along with the new capabilities and conveniences that new offerings deliver. As the pact of technological advancement continues to increase, therefore, so does the pace of new cybersecurity risks. While the number of such risks created over the past few decades as the result of new offerings is astounding, the areas described in the following sections have yielded a disproportionate impact on cybersecurity.

      Digital data

      In the last few decades we have witnessed dramatic changes in the technologies that exist, as well as who use such technologies, how they do so, and for what purposes. All of these factors impact cybersecurity.

      Consider, for example, that when many of the people alive today were children, controlling access to data in a business environment simply meant that the data owner placed a physical file containing the information into a locked cabinet and gave the key to only people the owner recognized as being authorized personnel and only when they requested the key during business hours. For additional security, the data owner may have located the cabinet in an office that was locked after business hours and which itself was in a building that was also locked and alarmed.

Today, with the digital storage of information, however, simple filing and protection schemes have been replaced with complex technologies that must automatically authenticate users who seek the data from potentially any location at potentially any time, determine whether the users are authorized to access a particular element or set of data, and securely deliver the proper data — all while preventing any attacks against the system servicing data requests, any attacks against the data in transit, and any of the security controls protecting the both of them.

      Furthermore, the transition from written communication to email and chat has moved tremendous amounts of sensitive information to Internet-connected servers. Likewise, society’s move from film to digital photography and videography has increased the stakes for cybersecurity. Nearly every photograph and video taken today is stored electronically rather than on film and negatives — a situation that has enabled criminals situated anywhere to either steal people’s images and leak them, hold people’s valuable images ransom with ransomware, or use them to create turmoil in people’s personal lives by creating fake profiles on dating sites, for example. The fact that movies and television shows are now stored and transmitted electronically has likewise allowed pirates to copy them and offer them to the masses — sometimes via malware-infested websites.

      The Internet

      The most significant technological advancement when it comes to cybersecurity impact has been the arrival of the Internet era, and, more specifically, the transformation of the Internet from a small network connecting researchers at a few universities to an enormous worldwide communication system utilized by a tremendous number of people, businesses, and organizations. In recent years, the Internet has also become the conduit for communication both by billions of smart devices and by people remotely connecting to industrial control systems. Just a few decades ago, it was unfathomable that hackers from across the globe could disrupt a business, manipulate an election, create a fuel shortage, pollute drinking water, or steal a billion dollars. Today, no knowledgeable person would dismiss any such possibilities.

      Prior to the Internet era, it was extremely difficult for the average hacker to financially profit by hacking. The arrival of online banking and commerce in the 1990s, however, meant that hackers could directly steal money or goods and services — which meant that not only could hackers quickly and easily monetize their efforts, but unethical people had strong incentives to enter the world of cybercrime.

      Cryptocurrency

Compounding those incentives severalfold has been the arrival and proliferation of cryptocurrency over the past decade, along with innovation that has dramatically magnified the potential return-on-investment for criminals involved in cybercrime, simultaneously increasing their ability to earn money through cybercrime and improving their ability to hide while doing so. Criminals historically faced a challenge when receiving payments since the account from which they ultimately withdrew the money could often be tied to them. Cryptocurrency effectively eliminated such risks.

      In addition, not only has the dramatic rise in the value of cryptocurrencies held by criminals over the past few years enriched many crooks, providing evildoers with the resources to invest in enhancing their cyber-arsenals, but also the public’s perception of cryptocurrency as a quick way to get rich has helped scammers perpetuate all sorts of social engineering–based cybercrimes related to cryptocurrency investing.

      Furthermore, the availability and global liquidity of cryptocurrency has helped criminals launder money obtained through the perpetration of all sorts of crimes.

      Mobile workforces and ubiquitous access

      Not that many years ago, in the pre-Internet era, it was impossible for hackers to access corporate systems remotely because corporate networks were not connected to any public networks, and often had no dial-in capabilities. Executives on the road would often call their assistants to check messages and obtain necessary data while they were remote. In later years they may have connected to corporate networks via special dial-up connections using telephone-line–based private lines for extremely limited access to only one or two specific systems.

      Connectivity to the Internet, of course, created risk, but initially most firewalls were set up in ways that did not allow people outside the organization to initiate communications — so, short of firewall misconfigurations and/or bugs, most internal systems remained relatively isolated. The dawn of e-commerce and e-banking, of course, meant that certain production systems had to be reachable and addressable from the outside world, but employee networks, for example, usually remained generally isolated.

      The arrival of remote access technologies — starting with services like Outlook Web Access and pcAnywhere, and evolving to full VPN and VPN-like access — has totally changed the game.

      Likewise, even in the short time since the first edition of this book was published, the dramatic reduction in the cost of cellular-based high-speed Internet access and the availability of mobile data plans supporting data limits sufficient enough to allow effective full-time use have dramatically reduced the need for utilizing public Wi-Fi connections. Risks that one might have deemed reasonable to take a few years ago in order to achieve various business aims have become unnecessary, and as such, policies and procedures regarding public Wi-Fi access must be updated, as is discussed later in this book in Chapters 7 and 21.

      Smart devices

      Likewise, the arrival of smart devices and the Internet of Things (the universe of devices that are connected to the Internet, but that are not traditional computers) — whose proliferation and expansion are presently occurring at a startling rate — means that unhackable solid-state machines are being quickly replaced with devices that can potentially be controlled by hackers halfway СКАЧАТЬ
