Humans are often regarded as the weakest link in a cybersecurity program. Whether resulting from manipulative cybersecurity tactics or limited cybersecurity awareness, human errors remain the most prevalent attack vectors in every information security program, no matter how sophisticated your cybersecurity stack may be.
In this post, we examine some of the human factors facilitating cybersecurity breaches and recommend security measures for fortifying what is arguably the most fragile line of defense of every cybersecurity strategy.
Human cyber risk refers to potential human behaviors that could result in a cyber incident. These could include clicking on malicious phishing email links or providing sensitive internal information to unauthorized persons.
Human risk is the potential for individuals to play a direct role in a security incident that may not be linked to a cyber attack. An example of this is the Microsoft PowerApps misconfiguration, which UpGuard discovered before it facilitated a large-scale data breach.
Human risks in cybersecurity are a challenging cybersecurity threat to mitigate. Unlike digital data breach attack vectors, like software misconfigurations, human cyber risks are difficult to anticipate and, therefore, prevent. Their environment-agnostic nature adds another level of complication, with the potential of impacting both digital interactions, such as phishing attacks, and social interactions, such as social engineering attacks occurring via phone calls.
In cybersecurity, a human vulnerability is any area of weakness that could result in a security breach. Unlike digital cyber threats, which could be exploited programmatically by reverse engineering software flaws, human vulnerabilities are exploited by manipulating human behavior.
The human element is complex, and not all individuals share the same vulnerabilities—some are more susceptible to a phishing attack than others. An experienced cybercriminal determines each person’s unique area of weakness and devises a plan to exploit that weakness to advance their cybercrime objectives.
Understanding the nuances between human cyber risks, human risks, and human vulnerabilities is essential for addressing the complete range of human elements contributing to operational disruptions, a discipline known as Human Risk Management.
The following is a high-level example of a risk management strategy across the three primary categories of human-related security exposures as part of a Human Risk Management program:
Human cyber risks
Human risks
Human vulnerabilities
Because human risks map to a variety of security incidents, they must be addressed holistically.
Human risks are predominantly concentrated at the IT security boundary, at the interface of cybercriminals, and in an organization’s private network. This is why human errors usually facilitate initial network access to unauthorized users. Cybercriminals aim to exploit this gateway, and they have cultivated their tactics to exploit the human factors of cybersecurity with the following types of attacks:
Even without prompting from hackers, human errors can permeate the information technology boundary with the following poor cyber hygiene actions:
The following statistics highlight the significant impact of human error in cybersecurity programs.
Understanding how to formulate a successful strategy for mitigating cyber risks associated with human errors beings with understanding the limitations of current approaches
Cybersecurity awareness training is a popular approach to human risk mitigation since it’s a mandatory requirement for many cyber regulations, including GDPR, HIPAA, FISMA, PCI DSS, and NYDFS. However, this approach alone is ineffective.
Training sessions and their subsequent quizzes usually guide users to the correct answers, allowing them to mindlessly rush through each session. Simply completing a training session is sufficient to achieve a passing grade and satisfy any regulatory requirements in this area.
A 2019 study found that mandatory training sessions for high-risk employees who failed phishing simulation tests did not improve human cybersecurity. Offenders were just as likely to click on a malicious email link again after the awareness training.
Compartmentalizing human cyber risk mitigation strategies into separate human risk categories produces a point-in-time risk management framework, encouraging false confidence about an organization’s human error potential.
Even when risk detection methods produce accurate insights, they only reflect an employee’s level of cyber threat awareness at the time of the assessment. Other critical factors arising between assessment schedules, such as falling victim to identity breaches, are not considered, significantly limiting the effectiveness of risk management processes.

Depending on point-in-time human cyber risk management, which is usually a by-product of a check-the-box mentality towards regulatory compliance, undermines the “Identify” and “Protect” pillars of the NIST CSF framework.

The most effective approach to Human Risk Management is a holistic consideration of all human factors leading to security incidents, quantified as a score representing each employee's evolving cyber risk exposure.
The most effective approach to Human Risk Management is a holistic consideration of the primary factors of human cyber risks leading to security incidents, which can be consolidated into three risk factors:
For an illustration of how UpGuard manages human risks across these three categories, watch this video.
The following more traditional human error mitigation strategies could still help reduce human errors leading to security breaches if augmented with a Human Risk Management platform as part of a unified Human Risk Management strategy.
A phishing simulation is a cybersecurity exercise in which employees are sent fake phishing emails to test their ability to identify and respond to these attacks. All interactions with these emails are tracked and analyzed to calculate each employee’s susceptibility to falling victim to phishing attacks.
Phishing simulations are only effective if coupled with other methods of human cyber risk monitoring. A simulated phishing attack may not occur when an employee is in a state of mind that’s most vulnerable to cybercriminal compromise, i.e., when they’re exhausted, highly stressed, or too distracted by their workload to consider the implications of their actions.
When combined with a human risk management platform, phishing simulations could reduce the User Identity factor of each employee’s cyber risk exposure, shifting the focus to other human factors increasing an organization’s risk of suffering a security incident.
Social engineering testing extends human vulnerability evaluations beyond email-based attacks to include scenarios involving phone calls (telephone vishing), social media messaging, and even physical interactions.
Social engineering testing aims to determine a company's level of cyber threat awareness beyond the digital realm. This helps employees understand that sensitive internal information can also be exposed through seemingly innocuous interactions, such as sharing the company’s WI-FI password or holding entry doors open as a kind gesture to a stranger without a swipe card.
Social engineering tests effectively evaluate a company’s baseline of digital and physical cyber threat awareness. However, due to the point-in-time nature of these tests, they don’t account for the volatility of cyber threat vigilance levels of employees between testing schedules, which could result in a false sense of corporate security.
