The much larger population is composed of application users. Even with a good recovery strategy, it is possible to have multiple days without your key HANA and other systems which could be financially devastating.īut this only addresses some of the potential avenues of attack and a relatively small population of employees and/or contractors. These types of attacks can be crippling and, without a strong recovery strategy, leave the attacked entity no choice other than to pay the hacker. This is one of the most common exploits used by ransomware hackers. These are critical because only those accounts with write authority to HANA and other critical system files can encrypt them and hold the keys to these files until a ransom is paid. admins with privileged access and other avenues by which admin level authority might be commandeered. As noted in that webinar, this addresses some angles of attack of hackers, i.e. Protecting HANA against Ransomware Attacks – Data and ApplicationsĪ few weeks ago, I posted a blog entry about securing SAP HANA systems against ransomware attacks from a Systems and OS perspective.
