How To Guard Against Ransomware

Enterprise anti ransomware software was designed to safeguard user data as a response to the phenomenon of ransomware which is a significant concern as well as one of the major security threats of the moment. It is, however, an entirely new kind of threat since massive ransomware attacks first appeared three years ago. it took a while before the public realized that ransomware was an emerging threat, distinct and more harmful than usual malware.

Naturally, the public believed that antivirus programs would be able to handle this new threat just as it has occurred with all kinds of security threats throughout the past. But, it was quickly established that traditional antivirus products do not have the capability of stopping and detecting ransomware to an adequate degree. The anti-malware method of actively stopping malicious processes does not work with ransomware since it mimics user behavior well. However ransomware is packaged in complicated applications that have features that are designed to thwart antivirus technologies such as Sandbox, Application Control, Heuristics and more. Only signature-based detection is able to stop ransomware, but unfortunately, it doesn’t protect against new or custom versions and is constantly updated.

In this sense there is a new, specialized anti-ransomware for enterprises software technologies have emerged to offer the protection of enterprises against ransomware. It detects ransomware in a reactive manner in response to the activities it observes on a system, but not in a proactive manner, prior to when it begins to execute. Here are the key advantages of anti-ransomware products that are specialized:

The detection of ransomware and the reactions

The method of detecting reactively ransomware provides a better detection method that will stop custom and new ransomware variants, without relying on signatures or updates. However this technique of behavioral analysis permits the ransomware to run which means that certain files could be encrypted at when the malware is shut down and removed from the system. Some versions also provide security of the Master Boot Record to protect against ransomware which tries to launch its own program. Additionally, there are detection methods which combine behavior analysis with honeypot detection methods that include putting decoy files on the computer and monitoring them. Certain solutions rely only on the latter, however their effectiveness in stopping ransomware is not certain.

In addition to stopping and removing the ransomware’s payload in the software, it can also allow IT administrators to handle the situation by shutting down the affected system, notifying the administrator and user, and, on rare instances to isolate the affected machine completely from networks.

In terms of the rate of detection, it is much higher than that of the traditional antivirus systems and allows for a quick response to ransomware-related incidents that reduce the time it takes to recover data and downtime. In the case of false positives, most implementations have a decent rate and in very rare instances it is able to keep a low percentage (next up to one) in false positives.

Real-time backup capabilities that are based on changes to files

Since detection can occur in a matter of minutes or seconds after ransomware is executed, anti-ransomware technologies must offer a means to retrieve the encrypted files before the ransomware procedure was shut down. Therefore, certain solutions incorporate the ability to backup in real-time to ensure that encrypted files are able to be recovered when the encryption process has been stopped.

There are many applications for enterprise anti-ransomware however, in general the strategy relies on analysing the changes to files and creating copies of files that have been altered in a suspicious manner. Certain solutions use the Windows shadow copy function to achieve this goal, however, there’s a significant danger in doing this since numerous ransomware families guarantee that data cannot be recovered using this method.

File protection capabilities

Alongside detecting ransomware, and restoring the affected data during the detection process some anti-ransomware products offer protection for files against ransomware by generating copies of user files that are placed in designated zones of the hard disk. This means that even if the ransomware attack the data, the malware will not be able to access the protected area and consequently, cannot attack the copies that are protected. This allows the data to be recovered in the event successful ransomware attacks. The safe repository could be used by backup tools to ensure that backups are encrypted.
