What type of encryption is employed by Sailpoint Zero Knowledge in the Virtual Appliance?

• A. AES 256
• B. Blowfish 64 bit
• C. RSA 2048
• D. 3DES

Answer: (C)

SailPoint's Zero Knowledge encryption mechanism in the Virtual Appliance utilizes RSA 2048 encryption. RSA, which stands for Rivest-Shamir-Adleman, is an asymmetric encryption algorithm that relies on the mathematical properties of prime numbers, making it secure for encrypting sensitive data. The 2048-bit key length signifies a robust level of security, as it is currently considered strong enough to deter even advanced cryptographic attacks.

Using RSA, data can be securely exchanged and validated without exposing the encryption keys used for the process. This mechanism is essential for maintaining confidentiality and integrity of identity data in SaaS applications and cloud environments. The Zero Knowledge principle ensures that even SailPoint does not have access to the actual data, further enhancing user privacy by allowing all operations to be conducted without knowledge of the data itself.

In contrast, while other encryption methods like AES 256 and Blowfish are widely used for symmetric encryption and provide strong protection, they function differently than RSA. Symmetric encryption uses the same key for both encryption and decryption, requiring secure key management and distribution. Additionally, 3DES, an older encryption standard, has largely been phased out due to vulnerabilities and performance issues, making it unsuitable for modern security requirements.

Thus, RSA 204
