[IDS] Edits suggested for HCD ESRs today

Hi Alan,

[clarified wording of three ESRs from today's IDS WG discussion]


Per Gerry and Graydon's comments, change 3.b.i. from:

HCD shall verify the integrity of initial boot, operating system, and
application software/firmware.

to:

HCD shall verify the hardware-anchored integrity of firmware/software,
including initial boot, operating system, and applications.

(delete both 3.a.ii. roots of trust and 3a.iii. secure boot ESRs)


Per Bill's comments, change second 4.a. from:

(Conditionally mandatory) Regardless embedded or Field-Replaceable, the
nonvolatile storage device should be encrypted to protect the document data
and/or HCD critical data.

to:

(Conditionally mandatory) If nonvolatile storage is present, then the
nonvolatile storage device (either embedded or Field-Replaceable) should be
encrypted to protect the document data and/or HCD critical data.

(revised to make the "condition" the prefix of the sentence)
Per today's discussion, change 4.c. from:

Do not store the encryption keys as a plaintext-form, obfuscated-form,
encoded-form or another obscure way. To protect these keys, HCD WG strongly
recommends using the dedicated security component such as TPM, security
element, or USB thumb drive.

to:

Do not store encryption keys in a plaintext-form, obfuscated-form,
encoded-form or another obscure way. To protect these encryption keys, HCD
WG
strongly recommends using the dedicated security component such as a TCG
TPM or Global Platform Secure Element.

(delete reference to the completely unsafe use of a USB stick for key
storage
because, even when encrypted, the USB interface itself is unsafe and has
been hacked often, including embedded malware from nation-states)


All - any further comments?

Cheers,
- Ira
