The ransomware threat continues to evolve. Today, high-profile and highly damaging ransomware attacks are becoming increasingly prevalent. Minimizing the cost and damage of these attacks demands rapid threat detection and response. So, how do you detect ransomware attacks? Drew Robb explains the techniques for ransomware detection in this article at CIO insight.
Techniques to Detect Ransomware Attacks
Detect Ransomware Through Abnormal Traffic
As an IT professional, you can detect ransomware at the network level. Anomalous traffic indicates ransomware infection or malware in general. When carrying out a large-scale data breach, hackers must send large amounts of data from inside the network to external systems. While cybercriminals may try to conceal these data transfers, they might create inconsistent network traffic that can be detected and traced back to the ransomware present on the system.
Check for Unusual Activities
“Out-of-the-ordinary activity—like file name or extension changes, data transfers, or permissions updates—can signal a ransomware attack in progress,” says Robb. To ensure this technique works, you must have a baseline for normal activity levels. Once you establish a baseline, it is easier for you to accurately spot attacks in progress.
Conduct Sandbox Testing
When working with new or unrecognized files, test them in an isolated virtual machine before exposing them to your network. This will help you prevent threats from harming your broader network.
Isolate Sensitive Data to Detect Ransomware
Data isolation helps protect sensitive information. By isolating data via backups, you can save your files and detect strange network traffic generally directed toward the isolated data.
How to Prevent Ransomware Attacks
Implement Multi-Factor Authentication (MFA)
MFA reduces the chances of allowing unauthorized access to a company’s network. Furthermore, it ensures that network access is gained through two pieces of information—a password and a one-time authorization code.
Educate Employees on Security Guidelines
Ensure that your staff is aware of the risks. Encourage your employees to identify the most common signs of ransomware and other malware, use strong passwords and update them regularly, and examine the links and file attachments before clicking them.
Regularly Scan Your Infrastructure
Install anti-malware software to help you notice any possible threats. Modern anti-ransomware tools enable you to scan your entire system for existing viruses and active malware threats.
