Top five ways backup can protect against ransomware

▤ Summary

According to security supplier Trustwave, ransomware attacks outstripped payment card information theft last year. Cloud providers themselves are at risk of ransomware attacks, warns analyst Fred Moore of Horison Information Strategies. Again, CIOs should review policies for frequency of backups, especially how often data is backed up to off-site locations (including the cloud) and mechanically separated media, such as tape. Ransomware often uses time delays to avoid detection, or “attack loops” to target apparently clean systems. As well as strict air-gap policies – such as taking media offline as quickly as possible – up-to-date malware detection tools are essential, as is system patching.
