• DB_PROT_LEVEL_PKT—Authenticates that all data received is from the client.
  
  
• DB_PROT_LEVEL_PKT_INTEGRITY—Authenticates that all data received is from the client and that it has not been changed in transit.
  
  
• DB_PROT_LEVEL_PKT_PRIVACY—Authenticates that all data received is from the client, that it has not been changed in transit, and protects the privacy of the data by encrypting it.
