The cybersecurity solutions market has ballooned to become a multibillion-dollar industry, perhaps pushing some organizations to focus too much on deploying the latest advanced technology-based defenses. However, it’s important to remember that cybersecurity is not only about tech – it’s about people, too.
With the right skills and knowledge, individuals within an organization can be an effective line of defense against cyber attacks. Only well-trained employees can spot suspicious emails, links, and attachments, preventing them from infecting the organization’s systems. Indeed, to protect your company’s digital assets effectively, you’re going to need a strong human firewall.
What Is a Human Firewall?
A human firewall refers to the combined effort of all employees to protect their organization from cyber attacks. It relies on the tenet that every individual has a role to play in the fight against cyber threats.
Verizon’s 2024 Data Breach Investigations Report (DBIR) findings revealed that the human element played a part in 68% of breaches. Today’s cyber criminals know that cyber defense tech is reasonably capable of stopping the lion’s share of breach attempts, which is why social engineering attacks are on the rise.
Technology alone can’t stop every phishing email from reaching people’s inboxes, meaning that every employee, from the CEO to interns, is a vital part of the human firewall.
How a Potent Human Firewall Stops Cyber Attacks
How, exactly, can the human firewall help prevent cyber attacks? After all, technology is often seen as the primary defense against cyber threats. Here are a few specific ways organizations can build human firewalls to complement their cybersecurity tech solutions in fighting against threats.
Security Awareness Training
A strong human firewall can be developed with regular training sessions on the latest cyber threats and attacker tactics, such as phishing styles, malware distribution techniques, and social engineering attacks. Even the Cybersecurity and Infrastructure Security Agency (CISA) recommends security awareness training, asserting that “that many security breaches are avoidable if people are trained to spot and avoid phishing messages.”
These days, security awareness training is no longer confined within the four walls of a conference room. For example, some interactive games simulate real-world cyber threats, such as phishing, allowing employees to learn through gamification.
Some organizations also employ microlearning, where cybersecurity training is delivered through short, bite-sized modules to efficiently train employees.
Clear Reporting Guidelines
The effectiveness of human firewalls depends on the culture an organization fosters. There must be set and easy-to-follow reporting guidelines to encourage employees to report suspicious activities, such as unexpected emails, weird website behavior, and notifications of failed login attempts.
Additionally, organizations should establish clear and accessible reporting channels to help employees flag anything suspicious immediately.
Strong Security Hygiene
According to Microsoft’s Digital Defense Report, basic security hygiene is effective and can protect against 99% of cyber attacks.
This hygiene involves enabling multi factor authentication (MFA), using strong passwords, applying zero-trust principles, and keeping systems updated with the latest security patches. Ensuring that all of your employees adhere to these standards takes training and vigilance.
Secure Data Handling
Human firewalls may only be considered effective if they can protect sensitive data from exposure and unauthorized access. The first step is to teach employees to classify data based on sensitivity. They must be able to identify if a particular data point constitutes personally identifiable information (PII), intellectual property, financial data, or other data types. Employees also need to know how the data is protected and who can access it.
Secure data sharing should also be established and taught across your organization, especially for sensitive information. This practice involves specifying standard encryption and secure file transfer protocols.
Safe Browsing Practices
Unlike traditional firewalls that stay put, human firewalls are dynamic. People browse the internet using different devices throughout the day. Therefore, it’s essential to educate them on basic safe browsing practices. These include making sure only to access secure websites (HTTPS), avoiding downloading from untrustworthy sources, and exercising caution with pop-ups and redirects.
Additionally, training employees on browser security features and plug-ins can significantly enhance their online safety. Tools like ad and script blockers can provide an extra layer of protection.
Automation
It may sound counterintuitive in the context of human firewalls, but automating repetitive tasks can help make them more effective. For example, software patches, updates, and password expiration alerts can be automated to ensure the human firewall does not overlook these critical tasks.
Network scans and phishing detection can also be automated as a first line of defense. Ultimately, automation can handle routine tasks, while the human firewall interprets alerts, exercises sound judgment, and makes critical decisions.
Characteristics of an Effective Human Firewall
When the human firewall is well-educated in cybersecurity, they become vigilant and more likely to incorporate the zero-trust principle in their day-to-day activities. They triple-check device and software settings and thoroughly scrutinize emails.
They can identify threats and respond accordingly, primarily by reporting to the proper channels right away. As a result, human firewalls can effectively prevent or minimize the impact of cyber attacks.
