This week, companies across at least 64 countries fell victim to a cyberattack attack known as Petya, which encrypted the hard drives of thousands. Making matters worse is the fact that it exploited the security flaw that enabled past ransomware around the globe in May.
Here are six key tips that enterprises can take to better manage ransomware risks, according to PwC.
Enterprises should conduct frequent risk assessments that seek to understand how sophisticated hackers might be able to undermine their security system.
Companies must strengthen their ability to rapidly identify, detect, and contain threats when they do occur.
Individual user systems and important servers should be able to be restored rapidly from backups in the event of a breach. Backups should be tested regularly and thoroughly to ensure a smooth recovery.
Enterprises must ensure formal procedures exist in which employees and those responsible for managing high-priority security incidents are able to streamline the organization's response to ransomware attacks.
The most common ransomware delivery vector is phishing emails. IT leaders can help prevent ransomware from entering their network by training employees in the latest security threats and how to spot spam and phishing emails.
As mentioned in our previous blog post earlier this month, effective patch management is one of the keys to preventing malware and any malicious activity. You can read more about effective patch management on our blog.
