Ransomware-Resilient Self-Healing XML Documents

In recent years, various platforms have witnessed an unprecedented increase in the number of ransomware attacks targeting hospitals, governments, enterprises, and end-users. The purpose this is to maliciously encrypt documents files on infected machines, depriving victims access their data, whereupon attackers would seek some sort a ransom return for restoring legitimate owners; hence name. This cybersecurity threat inherently cause substantial financial losses time wastage affected organizations users. A great deal research has taken place across academia around industry combat mitigate its danger. These ongoing endeavors resulted several detection prevention schemas. Nonetheless, these approaches do not cover all possible risks losing data. paper, we address facet provide efficient solution that ensure recovery XML from attacks. paper proposes self-healing version-aware (SH-VARR) framework documents. proposed based novel idea using link concept maintain file versions distributed manner while applying access-control mechanisms protect being encrypted or deleted. SH-VARR experimentally evaluated terms storage overhead, requirement, CPU utilization, memory usage. Results show snapshot size increases proportionately with original size; required less than 120 ms are 1 MB highest utilization occurs when bzip2. Moreover, zip gzip used, usage almost fixed (around 6.8 KBs). contrast, it 28 KBs bzip2 used.
