Enterprise anti-ransomware software is designed to safeguard user data in response to the ransomware threat that is a serious threat as well as one of the most significant security threats of the moment. But, it’s an entirely new kind of threat since significant ransomware attacks began over three years ago. it took a while before the public realized that ransomware was an entirely new threat that is different and more harmful than usual malware.
Naturally, many were expecting antivirus software to deal with this new threat just as it has occurred with all kinds of security threats throughout the past. However, it was discovered that the standard antivirus programs aren’t effective in stopping and detecting ransomware to an adequate degree. The anti-malware method of stopping malicious processes in a proactive manner does not work with ransomware since it mimics user behavior well. However ransomware is packaged in complicated software with features that are specifically designed to block antivirus technology such as Sandbox, Application Control, Heuristics and so on. Only signature-based detection is able to stop ransomware, but unfortunately, it does not protect against new or custom variants and needs constant updates.
In this sense there are new anti ransomware enterprise-specific software technologies have emerged to offer the protection of enterprises against ransomware. It detects ransomware in a reactive manner by analyzing the actions it performs on a system, but not in a proactive manner, prior to when it can be executed. These are the major characteristics of the anti-ransomware software that is specialized:
Responses to ransomware and detection
The method of detecting reactively ransomware provides a better detection system that can block custom and new ransomware variants and not rely on signatures or updates. However this method of behavioral analysis permits the ransomware to run in a way that certain files could be encrypted by the time that the malicious process has been stopped and is subsequently quarantined. Certain implementations also offer security of the Master Boot Record to protect against ransomware trying to start up its own program. Additionally, there are detection strategies which combine behavior analysis and honeypot detection techniques. These include putting decoy files on the computer and monitoring them. Certain solutions rely only on the former, however their effectiveness in stopping ransomware is a questionable.
In addition to stopping and removing the ransomware’s malware and removing the ransomware payload, the anti-ransomware program allows IT administrators to handle the situation by shutting down the affected machine, informing the administrator and user, as well, and in some rare cases to isolate the affected machine away from network.
In terms of the rate of detection, it is much higher than that of conventional antivirus software and allows for a quick response to ransomware attacks which reduces the amount of downtime and loss of data. If it comes to false positives, most implementations have a decent rate and in very rare instances it’s possible to ensure a minimal amount (next up to one) in false positives.
Backup capabilities in real-time based on changes to files
Because the detection occurs within seconds or minutes after the ransomware is executed, anti-ransomware technologies should provide a method to retrieve encrypted files prior to the time that the ransomware process ended. Therefore, certain solutions incorporate an automatic backup system that is designed to ensure that encrypted files can be retrieved when the encryption process has been stopped.
There are a variety of solutions for anti-ransomware in the enterprise However, generally, the strategy relies on analysing modifications to files and making copies of the files that have been altered in a suspicious manner. Certain solutions use the Windows shadow copy function to accomplish this, however there’s a danger when using this method since the majority of ransomware families ensure that data cannot be recovered this way.
File protection capabilities
Alongside detecting ransomware, and restoring the affected data during the detection process some anti-ransomware products also offer protection against ransomware through the creation of copies of user data to secured zones in the local drive. This guarantees that, even if the ransomware attack the data, the malware is unable to access the protected zone , and consequently, cannot attack the copies that are protected. Technically , this allows data to be recovered in the event successful ransomware attacks. The safe repository could be utilized by backup software to ensure that backups are encrypted.
