The terms "cybersecurity" and "information security" are often used interchangeably, but there is a slight difference between them. Cybersecurity focuses on protecting computer systems and networks from online threats, while information security covers a wider scope by protecting data in all forms. Cybersecurity mainly focuses on external threats, while information security considers both internal and external risks. Organizations should adopt comprehensive information security strategies to reduce the risk of breaches and leaks with serious consequences. Integrating cybersecurity and information security is key in today's digital world to ensure protection against cyber threats and defend valuable data.
