7 Steps to Prevent and Minimize the Impact of Ransomware

7 Steps to Prevent and Minimize the Impact of Ransomware

From small organizations to large enterprises, ransomware attacks are happening everywhere. We can all help prevent them by continuously updating our knowledge, staying alert, and using reputable anti-ransomware software. Below are seven essential steps to help prevent attacks and minimize the impact of ransomware.

What Is Ransomware?

First, it is important to understand what ransomware is. It is a type of malicious software that blocks access to systems, devices, or files until a ransom is paid. Ransomware achieves this by encrypting files on endpoints, threatening to delete data, or restricting system access.

It is especially dangerous when targeting critical institutions such as hospitals, emergency call centers, and other vital infrastructure.

7 Steps to Prevent Ransomware Attacks

1. Regularly Back Up Data

The Multi-State Information Sharing and Analysis Center (MS-ISAC) recommends backing up critical data as the most effective way to recover from ransomware attacks.

However, backups must be properly protected and stored offline or offsite so they cannot be targeted by attackers. Cloud services can help reduce ransomware impact, as many platforms keep previous file versions that allow recovery of unencrypted data.

Be sure to test your backups regularly. In the event of a cyberattack, verify that backups are clean before restoring them.

2. Develop Incident Response Plans and Policies

Create an incident response plan so your IT security team knows exactly what to do in case of a ransomware attack. The plan should define roles and include shared contact information.

It should also list partners and vendors who need to be notified. Does your organization have a “suspicious email” policy? If not, consider implementing one company-wide. This helps train employees on how to respond to suspicious emails, such as forwarding them to the IT security team.

3. Review Port Settings

Many ransomware variants exploit Remote Desktop Protocol (RDP) port 3389 and Server Message Block (SMB) port 445.

Review these settings in both on-premise and cloud environments. Work with your cloud service provider to disable unused RDP ports and secure exposed services.

4. Strengthen Endpoint Management

Ensure your systems are configured with strong security settings. Secure configurations help reduce attack surfaces and close security gaps left by default settings.

CIS Benchmarks are a reliable and free resource that provides consensus-based security configuration standards for organizations.

5. Keep Systems Up to Date

Make sure all operating systems, applications, and software are updated regularly. Applying the latest patches helps close vulnerabilities that attackers may exploit.

Whenever possible, enable automatic updates to ensure timely installation of security patches.

6. Train Employees

Security awareness training is key to preventing ransomware attacks. When employees can recognize and avoid malicious emails, everyone contributes to protecting the organization.

Training programs teach staff how to identify suspicious links, attachments, and phishing attempts before clicking or downloading.

7. Deploy an Intrusion Detection System (IDS)

An Intrusion Detection System (IDS) monitors network traffic and compares it with known malicious signatures.

A strong IDS updates its signatures regularly and quickly alerts your organization when potential threats are detected.
