ABC Enterprise is a global operation. As such, it needs to send regular, confidential messages and data between offices to communicate important market information, employee decisions, financial decisions, etc., for management consideration and senior-level decision making. Since these decisions impact the local employees and global businesses, they suspect that these data may be prone to attacks from threat actors internally and externally. While one of the senior systems administrators suggested implementing steganography to achieve this objective, the IT Department head at another branch suggested implementing cryptography. The management team has now called you for expert advice to select the best method to implement in the enterprise.What should your advice be, and why?
Cryptography should be implemented because it allows information to be viewed only by authorized users and checks whether the information has been altered or changed by anybody. It also makes the information unclear, even if other users see it. Cryptography is a more advanced technology than steganography. These features make cryptography the right choice for the enterprise to implement.
