Common Human Vulnerabilities

Human behavior is one of the most significant vulnerabilities in any organization's cybersecurity posture, making people a primary target for social engineering and other attacks. Factors like inherent trust, emotional responses, lack of training, carelessness, and even malicious intent all contribute to this risk.

About this video

Technical safeguards can harden a network significantly, but the human element introduces vulnerabilities that are far more difficult to control. Attackers routinely target people rather than systems because human behavior is predictable in exploitable ways. Trust, which is a natural and generally positive social trait, becomes a liability in cybersecurity contexts when employees act on unverified requests or assumptions. Emotional responses to urgency, fear, or authority can also lead individuals to bypass sound judgment, making them susceptible to manipulation tactics commonly used in social engineering attacks. Beyond these behavioral tendencies, practical gaps in knowledge, training, and experience leave many users unable to recognize or respond appropriately to threats. Poor judgment and a tendency toward shortcuts or procedural non-compliance further compound organizational risk. Accidental misconfigurations and careless handling of sensitive information can cause significant damage even without any malicious intent behind them. In rarer cases, insider threats introduce a deliberate dimension to human-driven risk, where authorized users act against the interests of the organization for personal gain. Even skilled and security-aware professionals are not entirely exempt from this category of risk. Accidental information disclosure, an unintentional exposure of sensitive data, can occur regardless of an individual's expertise or vigilance. Taken together, these human factors make people one of the most consequential attack surfaces an organization must address, and underscore why user-focused security awareness and training are critical components of any comprehensive cybersecurity strategy.

Key terms

Social Engineering: A manipulation technique that exploits human psychology to trick individuals into revealing confidential information.
Threat Actor: An individual or group responsible for a security incident or attack.
Phishing: A social engineering attack that uses deceptive emails or messages to trick users into revealing sensitive information.
Vulnerability: A weakness in a system, application, or process that can be exploited by a threat actor.
Insider Threat: A security risk that originates from individuals who have authorized access to an organization's systems — such as employees, contractors, or partners — and misuse that access either maliciously or through negligence.
Accidental Disclosure: The unintentional exposure of sensitive or confidential information by an authorized user.

Transcript

One of the biggest weaknesses to our network is the human component.

We commonly implement things in a secure way to make sure our equipment is locked down, at least as much as we can be locked down. But there is still a big weakness we have on our network, and that's the people.

When an attacker is trying to analyze how to get into a network and what they're going to attack, one of their go-tos is going to be the human factor, the social engineering, getting somebody to gain them access into this system. And that's because we as humans are vulnerable and susceptible to certain things.

Trust

One of the reasons is we generally are trusting to other people. Now, this is a good thing in most cases. We want to be able to trust other people, to live this fulfilled life, to be able to rely on others for at least some things, not for everything. So there is this trusting that we do want to have to a certain degree, but that can be problematic when it comes to cyber security. If we just trust people and just do things for them, then this could be problematic.

Emotion, Knowledge and Habits

We also are emotional creatures, and so we react in certain ways. Well, some of those reactions can be really harmful to the organizations we work with.

Then we also have a lack of knowledge, experience, or common sense. I find that many times people are just not trained to do something, or maybe they understand what they're supposed to do but they just don't have the skills and knowledge to do it, or the experience to do it. And I just find some people really lack common sense. So they're maybe intelligent, but they just don't have common sense when it comes to their approach from a cyber security standpoint.

I also find certain people are accident-prone and just make misconfiguration changes, or tend to do things without really thinking through the process. And then sometimes I just find that people are lazy and they just don't want to do certain processes that you put into place.

Humans can also have some sort of malicious intent as well, that our users that are using the system could have something that they have planned for their own gain. So that could be problematic as well.

Mistakes

But even the best of us, who maybe are skilled and knowledgeable and have a lot of common sense and make sure we don't trust people, at least from a cyber security standpoint, even us are prone to making mistakes. And one of these mistakes is accidental information disclosure. There are times when people will accidentally disclose information. Well, that can be problematic for the company.

So this is one of the vulnerabilities. As humans, we're just vulnerable and prone to mistakes, and so we are one of the biggest weaknesses to a company or an organization.
