Ransomware continues to be one of the most damaging and costly cybersecurity threats today. Whether you’re an employee or leading an organization, knowing how to prevent ransomware is critical. While strong cybersecurity software is helpful, human error remains one of the most common entry points for ransomware attacks. That’s why adopting a proactive, people-first defense strategy is key.
In this blog, AISN’s Chief Operating Officer, Eddie McAndrew shares five essential ransomware prevention tips to help protect your systems, your data, and your peace of mind.
1. Start With Security Awareness Training
The most significant vector of attack is the person sitting in the seat. Firstly, train your users! The number one defense against ransomware is an informed and cautious user. According to security expert Norton, most ransomware attacks have been linked to poor protection practices by employees.
Ransomware attacks can begin with a phishing email, a suspicious link, or a deceptive attachment. Educating employees on how to recognize and respond to these threats is one of the most effective ransomware prevention strategies. Train staff not to click unfamiliar links, download unverified files, or share personal information with unknown contacts via email, text, or phone.
Tip: Regular security awareness training and phishing simulations can drastically reduce your risk of a successful ransomware attack.
2. Use Vulnerability Scanning and Endpoint Protection
Comprehensive endpoint protection and regular vulnerability scans are essential for identifying and closing security gaps before attackers can exploit them. Keep antivirus and anti-malware tools up to date, and use email/web filtering to block malicious content. Firewalls and access controls should be configured to limit malware spread and contain attacks early.
Tip: Contact AISN for expert services in vulnerability scanning and endpoint protection to strengthen your cybersecurity posture.
3. Back Up Your Data
Having a reliable backup and recovery system is your strongest safety net in the event of a ransomware attack. Maintain regular, automated backups with an extended retention schedule—at least 30 days. Ensure backups are stored offline or in isolated environments, so they remain untouched by ransomware infections that may linger undetected for weeks.
Tip: Test your backup and recovery process regularly to ensure fast restoration when you need it most.
4. Keep Systems and Software Up to Date
Outdated systems are prime targets for ransomware. Apply patches and security updates to your operating systems, software applications, browsers, and plugins as soon as they’re released. The sooner the update is implemented, the lower the chances your network is compromised. This also helps close known vulnerabilities that attackers often exploit.
Tip: Implement automated patch management tools to stay current and secure without manual effort.
5. Have a Ransomware Response Plan in Place
Preparation is critical. The key factor is having a plan laid out for what needs to be done when an attack does occur and succeeds in encrypting your data and files. By planning out the steps beforehand, an organization will have a much better chance of combating and remediating the incident, and minimizing asset loss, especially in critical sectors like healthcare.
Tip: Practice your response plan through tabletop exercises to identify gaps and improve readiness.
Ransomware Can Happen to Anyone—Be Ready
