We must remain vigilant and always be thinking about how to handle the next wave of cyberattacks. While external bad actors, ransomware and other malware, are the most common threats, malicious or even careless employee actions can also present cybersecurity risks. In other words, it is virtually a given that at some point most will suffer a failure, disaster or cyberattack. However, given the world’s economic and political climate, the customers I speak with are most concerned about their ability to detect and recover from a malicious ransomware attack.
My advice to these customers is that, beyond protection, organizations must be able to detect ransomware as early as possible to stop the threat and ensure their ability to remediate and recover. A backup solution that includes anomaly detection to identify changes in an environment that warrants the attention of IT is a must. Administrators must be able to tailor anomaly detection to their business’s specific systems and workflows, with capabilities such as customizable filtering and thresholds for each of their backup policies. And those anomalies must be immediately reported to management, as well as aggregated for future ML/analyzing purposes.
Of course, the next step after detecting the anomaly is providing the ability to recover in the event of a successful ransomware attack. This is best accomplished with an immutable backup copy of data (a.k.a., object locking) which makes certain that the data backup cannot be altered or changed in any way.
