Page 45: C Encryption Overview & Implementation
Targa Systems Division S4 Ethernet NAS DTS Installation Guide 32003272-1 Rev 5 Encryption Overview & implementation C.1 Overview Targa's Gen2 Series 4 Ethernet DTU (S4eDTU) supports Logical Volume encryption on a per-partition basis. The volume is encrypted using the AES algorithm with a user selected 128/192/256 bit key size in the Cipher Block Chaining (CBC) mode with an S4eDTU generated Encrypted Salt-Sector Initialization Vector (ESSIV). - Page 46 Targa Systems Division S4 Ethernet NAS DTS Installation Guide 32003272-1 Rev 5 C.3 Creating & Managing Encrypted Volumes The S4eDTU supports the creation of up to 4 partitions per DTD. Encrypted partitions will be created by reallocating an existing NAS partition via the DTD Setup partition management support page.
- Page 47 Targa Systems Division S4 Ethernet NAS DTS Installation Guide 32003272-1 Rev 5 C.3.2 Manage Encrypted Partition Each LUKS encrypted volume has 8 key slots (passphrases). The administrative user can either “Enable” a key slot by providing a passphrase or “Disable” by removing the passphrase (kill key slot).
- Page 48 Targa Systems Division S4 Ethernet NAS DTS Installation Guide 32003272-1 Rev 5 C.4 Passphrase Exchange “ targa-unlock-volume” A remote entity will have to provide a passphrase(s) to the S4eDTU after each reboot (or door open/close cycle) in order to access the data on an encrypted volume(s).
- Page 49 Targa Systems Division S4 Ethernet NAS DTS Installation Guide 32003272-1 Rev 5 C.4.3 SSH User Authentication By default, ssh uses username/password authentication. It should be made clear that this authentication mechanism is also encrypted. No password is transmitted in the clear. As with the discussion of password entropy in section C.2, it is most important that good quality passwords are chosen.

Targa Systems Division S4 Ethernet NAS DTS Installation Guide 32003272-1 Rev 5 Network Data Capture Function With F/W version 3.1.8 and above, the Targa Series 4 NAS DTU has the ability to log network traffic to the removable Data Transfer Device (DTD). This capability uses tcpdump v4.1.1 (www.tcpdump.org) to capture information from the network in a libpcap v1.1.1 format that can be later replayed by tools such as tcpdump or Wireshark (www.wireshark.org). - Page 54 Targa Systems Division S4 Ethernet NAS DTS Installation Guide 32003272-1 Rev 5 netcapture – control parameters and filter commands ETHx_NC_BASENAME Change capture file basename (runY.pcapZ is unchanged) eg: ETH0_NC_BASENAME="netcap-eth0-" ETHx_NC_DEST Specify “destination” directory within DTD where netcapture was found … can be a different partition or directory to store the capture files eg: ETH0_NC_DEST= "part2/capture"...
