The average cost of data breach in India grew 7.29 percent year-over-year to reach Rs 12.8 crore from Rs 11.9 crore last year, said a new study by IBM on Tuesday.

Per capita cost per lost or stolen record reached Rs 5,019, which represents an increase of 9.76 percent from the prior year, said the "Cost of a Data Breach" report.

The root cause for 51 percent of data breaches was malicious or criminal attacks, system glitches contributed to 27 percent of breaches and human error led to 22 percent of breaches in India, the findings showed.

"India is witnessing a significant change in the nature of cyber-crimes, it is now extremely organised and collaborative," Vaidyanathan Iyer, Security Software Leader, IBM India/South Asia, said in a statement.

"Organisations need to significantly invest in three core areas when it comes to cybersecurity -- risk assessment based on business objectives, cognitive threat management and ensuring digital trust," Iyer added.

The findings are based on in-depth interviews with more than 500 companies around the world that suffered a breach over the past year.

The study also examined the cost of data breaches in different industries and regions, finding that data breaches in the US are vastly more expensive - costing $8.19 million, or more than double the average for worldwide companies in the study.

Costs for data breaches in the US increased by 130 percent over the past 14 years of the study; up from $3.54 million in the 2006 study.

For the ninth year in a row, healthcare organisations had the highest cost of a breach - nearly $6.5 million on average - over 60 percent more than other industries in the study.
