Due to the increasing number of computer systems and the wireless network standards that are used to connect them, cybersecurity is becoming more critical. This is also due to the growth of the Internet of Things (IoT) alongside the increasing number of smart devices.

The complexity of the technology and politics involved in cybersecurity makes it one of the world’s most challenging (and threatening) issues today. This article aims to provide a historical overview of the evolution of this field.

The Origins

The evolution of cybercrime has been observed since the first computers were connected to the Internet. Due to the nature of the threats presented today, the risk level that computer users are exposed to has increased.

Despite the technological advancements that have occurred in the field of cybersecurity, criminals are still constantly developing new ways to infiltrate and collect information. They can use ransomware and malware to take down various types of businesses.

The 1970s

The initial development of cybersecurity was observed during the 1970s when Bob Thomas created a program known as Creeper, which could allow it to move across the ARPANET network. This was part of a test, as Ray Tomlinson developed a Reaper program, which chased and deleted the program. It was the first example of a self-replicating program and the first antivirus software.

The 1980s

The birth of commercial antivirus in 1987 was a controversial issue, primarily due to the competition to be the first. During this period, Kai Figge and Andreas Lüning released their first antivirus for the Atari ST. Simultaneously, three Czech Republic residents created the first version of NOD. Following this, John McAfee founded McAfee and VirusScan.

The 2000s

During the 2000s, the rise of professional cybercrime led to an increasing number of criminal organizations funding attacks. Due to the seriousness of the crimes, the sentences handed down to those involved in hacking became significantly harsher. Viruses remain a threat despite the technological advancements that have occurred in the field of cybersecurity.

The Future

The cybersecurity industry is expected to grow steadily during the next few years. According to Statista, the global cybersecurity market is expected to reach around $345.4 billion by 2026. One of the most common threats that organizations are faced with is ransomware. Given the threat that ransomware currently poses, this shouldn’t surprise anyone.
