‘Personal data law needs to be tightened’ (Updated) Act should require online systems to be stress-tested and certified to avoid security breaches, say experts Pix for illustration purposes. PETALING JAYA: There is a need for a revision of legislation covering personal data if security breaches are to be avoided, or at the very least minimised, cyber security experts told theSun. Assoc Prof Dr Selvakumar Manickam of Universiti Sains Malaysia said data breaches can be extremely damaging, citing the leak involving Malaysian telcos in 2016, which gave rise to Macau scams. “As we rely more on online services, we have to share our personal data with these service providers to ensure smooth delivery of their services,” he said.
