Cyberspace is a threatened place. Over 300,000 new malware files are created every day, millions of digital identities are leaked, and new methods for compromising digital systems are constantly being devised. Most recently, the case of the Colonial Pipeline hack in the U.S. and also the spectacular SolarWinds hack have shown again how vulnerable critical infrastructures in the digital space are today, despite all precautions and security efforts.
This permanently insecure situation not only causes incredibly high costs, but also continually shakes confidence in the digital technologies and infrastructures without which our lives no longer function and our prosperity cannot be sustained. They also put the brakes on economic momentum. This applies in particular to the much-needed digital transformation of SMEs and the implementation and testing of new digital ideas by startups. Networked systems with inadequate protection provide a perfect ecosystem for spreading malware and scaling its damaging effects, enabling the DDoS and APT attacks on sensitive IT systems that occur every day, including in public administration, healthcare systems, and schools.
For the general population, the Internet and the Web are a daily commodity – not much goes on without access to the Internet and the digital services it provides – but to speak of secure, non-threatening, and enlightened use is far from reality. On a large scale, usage data and confidential personal data are disclosed thoughtlessly on the Internet, and for many users it does not even matter who gains access to this data. The widespread and extensive use of social media on foreign digital platforms is sad proof of this carelessness and lack of awareness of the problem. The lax handling of one’s own digital identities is also frightening. The most popular password worldwide is still “123456”, and it is used to “protect” about 1% (!) of all digital identities.
Establishing and ensuring cybersecurity is a very complex undertaking. Each new smart device and user adds to the complexity of the digital space and potentially provides new gateways for cybercriminals and cyberattacks. Interestingly, dealing with, combating and mitigating threats in cyberspace can be compared very well with the state of societal hygiene measures to maintain and raise the level of health and to prevent and combat diseases and epidemics. There, too, the spread of diseases depends not only directly on the behavior of people themselves, but also on the existence and condition of appropriate public infrastructures. In light of such a comparison, the digital space and our cyber vulnerability currently find themselves in a situation similar to that found worldwide in the pre-industrial age with regard to the health issue: ignorance of the causes of diseases, lack of hygiene awareness among the population, and lack of sanitary infrastructures for the general population.
It was only 110 years ago when the spell of biological epidemics was broken, at least in the Western world. At that time, the “1st International Hygiene Exhibition” took place in Dresden, Germany. It attracted more than five million visitors at the time, underscoring a claim to world stature. This “World Health Exhibition” of 1911 documented the breakthrough of a social movement that had already formed on a broad front in the 19th century and had set itself the goal of familiarizing broad sections of the population with the rules of health and hygiene in order to increase public health. As a result, infectious diseases in particular, which were widespread in Western societies, declined rapidly, leading to greater health, well-being and economic prosperity.
The current pandemic reminds us that human existence and the prosperity of societies are under constant threat. Before the Industrial Revolution, epidemics were permanent companions of mankind. In Europe, the severe plague epidemics are well anchored in the collective memory. Also, everyone has heard of epidemics introduced by colonists in the Americas. Disease and pestilence have been a pervasive leitmotif of human civilizations, in Europe at least until the Industrial Revolution, and in some regions of the world to this day. They brought disease and death, were accompanied by economic decline and stagnation, sparked or intensified political and religious extremism, and in the worst cases led to the demise of entire cultures.
Since the era of Enlightenmen,t we have been increasingly successful in counteracting the spread of epidemics and diseases and increasing public health. Research into the causes of diseases was carried out on a scientific basis. Bacteria and viruses were discovered as pathogens and triggers of epidemics, which were able to multiply well in contaminated water, through poor cleanliness and lack of waste disposal. The response of the Enlightenment was to educate people at large about the causes of disease, to propose simple measures to diminish ecosystems for bacteria and viruses, and to build societal infrastructures – both private and governmental – to make it more difficult or impossible for pathogens to spread.
Thus, a broad “hygiene movement” formed in the 19th century, manifesting itself in the form of associations, government regulations, infrastructure projects, and private initiatives by industrialists. Hygiene associations ran large-scale educational campaigns to establish simple hygiene rules, such as hand washing, as a cultural practice. Physicians and scientists, such as the St. Gallen physician Jakob Laurenz Sonderegger, and representatives of the Red Cross societies succeeded in bringing hygiene issues relating to the handling of air, water, housing and food into widespread discussion via numerous regional groups that branched out deep into working-class milieus. Hygiene guidelines for work in hospitals or at factory workplaces were also developed and their observance enforced.
The state invested heavily in science and research to discover the causes of diseases and develop effective preventive measures and medicines. The discovery of the pathogens of syphilis (at the Berlin Charité), tuberculosis, and cholera (by Robert Koch, founding father of modern microbiology) were milestones of research. Ignaz Semmelweis proved that pathogens could be contained by disinfection, and doctors henceforth washed their hands when in contact with patients. Joseph Lister used disinfectants for wounds before surgical interventions, and Louis Pasteur developed the process that is still used today to disinfect food by heating it.
Infrastructurally, too, decisive steps were taken to make it easy for people to keep themselves clean. Although there was already a sewer system for wastewater disposal in Roman antiquity with the “Cloaca Maxima,” these systems did not become widespread until the 19th century, starting in the European metropolises of Vienna, Hamburg, London, and later Berlin. Similarly, drinking water and fresh water supply via cast iron pipe systems could not be widely spread and installed to provide clean water to households until the Industrial Revolution.
These measures were flanked by private initiatives, such as that of Odol founder Karl August Lingner, who in the wake of the “1st International Hygiene Exhibition” in Dresden, founded the “German Hygiene Museum” in 1912, which to this day is known far beyond Saxony. The museum was conceived as a place of education on public health and is still today a platform for various information events around basic hygiene and health.
Today, it seems natural to us to have sanitary infrastructures in every home. Education on cleanliness measures such as hand washing, dental care or other cleanliness measures begins as early as infancy. This has not only promoted general health, but also increased life expectancy and ultimately contributed to greater economic stability and prosperity.
Seen in this light, we can learn a great deal from the historic hygiene movement of the 19th century for developing strategies to contain and combat cyberthreats. In many respects, we are still in a similar situation in the field of IT security that prevailed in the Middle Ages with regard to infectious diseases: the Internet and our dependence on its increasingly widespread use is a wonderful biotope for digital diseases and epidemics, like the expanding cities in the pre-industrial age.
Cyberthreats seem like an uncontrollable external force whose origins we do not know. Far too often, businesses and other institutions hope (and “pray”) not to be affected by the compromise of their IT systems. In particular, SMEs and startups are at risk to their existence if cyberattacks are successful. Attributions remain vague and culprits are quickly found to blame without compelling evidence, and exclusion as in the case of foreign technology is commonplace. Often, there is no alternative but to completely abandon the IT systems in question and rebuild them.
Not only is there a lack of secure manners on the part of users of digital systems, i.e. there is no digital hygiene awareness, but there is also a lack of secure and sovereign IT infrastructures for state administration and its interaction with citizens, as well as a lack of binding standards for the development of trustworthy and reliable IT systems. There is a lack of “sewerage and sanitation” in the digital world, which is very conducive to the spread of malware and the success of cyberattacks.
“Governance” structures are also not yet sufficiently adapted to the necessities and paradigms of the digital world. Responsibilities for IT security are fractionalized, and the pursuit of cyberthreats follows the logic of national boundaries and sole responsibility of state action. This is not appropriate for cyberspace, where national borders play virtually no role and the most powerful actors are not states but large digital companies.
Just as with controlling biological pandemics, we need a concerted effort by policymakers, business, and civil society – we need a digital hygiene movement. The good news is that we have the means and knowledge to address digital hygiene on a broad scale. But it needs the understanding and the political will, and the economic incentives are there.
As with biological pandemics, digital malware spreads along digital transmission media (networks and IT infrastructures) and their weakest links. 90% of all cyber risks can be avoided by following basic digital security rules. However, these must become as natural for everyone as washing one’s hands and brushing one’s teeth.
In education, we now have powerful tools to provide low-threshold access to knowledge that will protect us in cyberspace. Via digital learning platforms such as openHPI and learning infrastructures such as the HPI School Cloud, the state, authorities, IT experts and companies can bring simple digital hygiene rules to all layers of the population.
It is a fact: Every student uses digital systems in their private environment on a daily basis, but education on how to use them safely is lacking. IT security and digital hygiene measures must be practiced early on with the help of digital school platforms, just like washing hands, swimming and traffic rules. No one needs to have a degree in computer science to do this. Basic digital rules can be practiced in structured form in various educational contexts via the many high-quality and low-threshold digital learning programs. The openHPI ecosystem alone, with partners from SAP, the World Health Organization, AI Campus, the eGov platform, etc., can already provide solid basic knowledge on digital education and digital hygiene.
In numerous corporate contexts, other learning platforms provide relevant courses for your employees, of which important contributions are offered through the Charter of Trust Education Taskforce – a network of globally-acting companies, research institutions, and government agencies. Increased use of secure and privacy-compliant digital platforms in school and other educational contexts will create a natural ecosystem in which many new low-threshold and free educational offerings can be made available. All that needs to be done is to ensure that these topics are included in teaching and training curricula.
Our efforts can also intensify in research and development. Aside from basic security rules, procedures must be developed to make it easy to check new IT systems for security vulnerabilities and opportunities for compromise. Ideally, there would be methods such as pasteurization for digital systems, which could be applied without much effort by SMEs and startups (as well as any citizen) to make their digital products secure.
It must also be possible to regularly exchange knowledge about vulnerabilities in common IT systems in a trustworthy manner in order to gain collective protection against known “pathogens”. Jointly operated IT infrastructures (even across national borders) can help here in order to install “IT security as a service” firmly in the portfolio of digital products and thus enable “herd protection”.
Complex IT security standards and certifications must be designed in such a way that they can be applied by everyone without great cost or prior knowledge, which can also be enabled through the use of shared infrastructures. These infrastructures would then be the sewers and fresh water pipes of the digital world, with which digital pandemics can be effectively prevented.
Finally, one can also think about establishing a “Digital Hygiene Museum” – quite possibly as a physical place that can be visited, for example, in the context of school field trips to get a comprehensive picture of cyber hygiene using “touchable” exhibits, such as live hacks. This could also be an important focal point for relevant information events, a meeting place for the exchange of science, business and politics, where the common will to achieve digital hygiene is regularly reinforced and reaffirmed.
We have it in our hands to initiate an epochal shift from the Middle Ages to the modern era in the digital world and, with the help of the resources of science, cooperation, and technology, to make cyberspace a safe and prosperous place for all people.
