Prevent Supply Chain Attacks with These 8 Tips

Supply chain attacks are among the most dangerous cyber threats today in the United States. Unlike direct attacks, where hackers target your systems head-on with malicious code, supply chain attacks exploit vulnerabilities in your vendors, software providers, and third-party partners. The consequences can be devastating—data breaches, financial losses, reputational damage, and regulatory fines. The good news? You don’t have to be a victim. By implementing strong security measures, you can significantly reduce your risk. The following are eight helpful strategies to protect your business and prevent you from supply chain attacks.

1. Vet Your Vendors Thoroughly Before Onboarding

Your supply chain is only as secure as its weakest link. If a vendor has poor cybersecurity practices, hackers can use them as a backdoor into your systems.

How to conduct a vendor security assessment? You ought to do the following: ask for compliance certifications for industry-standard security frameworks, review their breach history, evaluate their security policies covering software supply chain attacks, malicious code attacks, unauthorized access, and many more, as well as check for sub-vendor risks.

Top red flags to watch out for include not having any clear security policies, resistance to sharing compliance documentation, and a history of unreported breaches

Pro tip: create a standardised vendor security questionnaire to streamline evaluations and ensure your vendors will help you prevent attacks.

2. Enforce Strict Access Controls (Least Privilege Principle)

Why least privilege is critical? The more access a vendor has, the greater the risk. If their account is compromised, a malicious actor gains a wider reach into your critical infrastructure.

How to implement the least privilege? Check out the following tips:

• Only grant minimal access to vendors with permissions they absolutely need;
• Assign permissions based on job functions;
• Require Multi-Factor Authentication (MFA) for an extra layer of security; and
• Remove access for inactive vendors or employees.

For example, a marketing agency working with your company doesn’t need access to financial records. Restrict them to only the files and systems relevant to their role.

If you need professional help with your security needs, you can work with the cybersecurity team at Attentus and others like them. They’re equipped with the right tools and knowledge to help you with upholding security access control and so on.

3. Monitor for Anomalies in Real Time

Many supply chain attacks go undetected for months. Real-time monitoring helps you spot suspicious activity before major damage occurs.

Key monitoring strategies range from setting up alerts for suspicious activity (like too much network activity, unusual software updates, multiple failed access attempts with digital signatures, and so on) to assigning critical systems managers.

As a general rule, conduct regular log audits by checking for signs of unauthorized access and security incidents periodically. Take note of your observations too.

Risk monitoring can be tiresome. Luckily, you can delegate that to a managed service provider (MSP). If you’re based in Ohio, you can have a look at Akron’s top MSPs and pick your top choice to aid you in your security needs.

4. Patch and Update Software Immediately

Unpatched software is one of the easiest ways for hackers to breach your supply chain security.

Best practices for patch management are below:

• Automate updates where possible to reduce human error and delays;
• Prioritise critical patches of software products; and
• Require your third-party vendors to patch their software to control supply chain security risks.

5. Encrypt Data End-to-End

Why encryption is non-negotiable? If hackers intercept data in transit or at rest of a target organisation (like yours), encryption ensures they can’t read it.

How to encrypt your data effectively? First, secure all communications between you and vendors. Next, encrypt stored data by following industry-accepted methodologies. Finally, manage encryption keys securely; store them separately from encrypted data.

Take into account the following example. Instead of emailing sensitive files, use encrypted cloud storage with strict access controls.

6. Train Employees and Vendors on Security Awareness

Phishing, social engineering, and weak passwords cause most breaches. These can all be avoided if your whole team is well aware of how to spot them and deal with them.

How to build a security-aware culture in your organisation? You can:

• Conduct regular training to help team members spot phishing emails and fake invoices easily;
• Run simulated attacks and test your personnel’s responses; and
• Require vendors to train their teams as well. Why? Because their negligence can still affect you.

7. Develop a Joint Incident Response Plan

When a breach happens, confusion makes things worse. A clear response plan minimises damage caused by malicious activity.

Key steps in your plan include defining the roles (the who’s who like who contacts law enforcement, who manages the public, and so on), establishing communication protocols, carrying out regular drills, and many more.

8. Demand Transparency in Vendor Contracts

Why do legal protections matter? If a vendor causes a breach, you need recourse.

Key contract clauses to include in your partnerships include:

• Mandatory breach notifications wherein vendors must disclose incidents immediately;
• Right-to-audit clauses to help you verify their security teams; and
• Liability provisions detailing information like who pays for damages from a vendor-caused breach and others.

What if a vendor refuses? If they won’t agree to security terms, consider it a red flag.

Final Thoughts: Stay Proactive, Not Reactive

Supply chain attacks won’t disappear, but you can make your business a much harder target. Start with one or two of these tips, then expand your defenses over time. Remember: cybersecurity isn’t just your responsibility—it’s a shared effort with every vendor you work with.

By taking action today, you’ll reduce risk, protect sensitive data, and keep your business safe from the growing threat of supply chain attacks
