Data Breaches are result of:
• Poor IT operational practices (e.g. late decommission of servers)
• Application vulnerabilities
• Advanced Persistent Threat (APT)
• Deficiency in outsourcing management
• Etc.
Organizations need to have a holistic security strategy – combining people, process and technology to reduce exposure to current & future attacks
