Subject Re: 答复: [DISCUSSION] Merging HDFS-7240 Object Store (Ozone) to trunk
Date Fri, 20 Oct 2017 16:37:26 GMT
I previously sent this same email from my work email and it doesn't seem to
have gone through - resending from apache account (apologizing up from for
the length)....

For such sizable merges in Hadoop, I would like to start doing security
audits in order to have an initial idea of the attack surface, the
protections available for known threats, what sort of configuration is
being used to launch processes, etc.

I dug into the architecture documents while in the middle of this list -
nice docs!
I do intend to try and make a generic check list like this for such
security audits in the future so a lot of this is from that but I tried to
also direct specific questions from those docs as well.

1. UIs
I see there are at least two UIs - Storage Container Manager and Key Space
Manager. There are a number of typical vulnerabilities that we find in UIs

1.1. What sort of validation is being done on any accepted user input?
(pointers to code would be appreciated)
1.2. What explicit protections have been built in for (pointers to code
would be appreciated):
  1.2.1. cross site scripting
  1.2.2. cross site request forgery
  1.2.3. click jacking (X-Frame-Options)
1.3. What sort of authentication is required for access to the UIs?
1.4. What authorization is available for determining who can access what
capabilities of the UIs for either viewing, modifying data or affecting
object stores and related processes?
1.5. Are the UIs built with proxying in mind by leveraging X-Forwarded
1.6. Is there any input that will ultimately be persisted in configuration
for executing shell commands or processes?
1.7. Do the UIs support the trusted proxy pattern with doas impersonation?
1.8. Is there TLS/SSL support?


2.1. Do the REST APIs support the trusted proxy pattern with doas
impersonation capabilities?
2.2. What explicit protections have been built in for:
  2.2.1. cross site scripting (XSS)
  2.2.2. cross site request forgery (CSRF)
  2.2.3. XML External Entity (XXE)
2.3. What is being used for authentication - Hadoop Auth Module?
2.4. Are there separate processes for the HTTP resources (UIs and REST
endpoints) or are the part of existing HDFS processes?
2.5. Is there TLS/SSL support?
2.6. Are there new CLI commands and/or clients for access the REST APIs?
2.7. Bucket Level API allows for setting of ACLs on a bucket - what
authorization is required here - is there a restrictive ACL set on creation?
2.8. Bucket Level API allows for deleting a bucket - I assume this is
dependent on ACLs based access control?
2.9. Bucket Level API to list bucket returns up to 1000 keys - is there
paging available?
2.10. Storage Level APIs indicate “Signed with User Authorization” what
does this refer to exactly?
2.11. Object Level APIs indicate that there is no ACL support and only
bucket owners can read and write - but there are ACL APIs on the Bucket
Level are they meaningless for now?
2.12. How does a REST client know which Ozone Handler to connect to or am I
missing some well known NN type endpoint in the architecture doc somewhere?

3. Encryption

3.1. Is there any support for encryption of persisted data?
3.2. If so, is KMS and the hadoop key command used for key management?

4. Configuration

4.1. Are there any passwords or secrets being added to configuration?
4.2. If so, are they accessed via Configuration.getPassword() to allow for
provisioning in credential providers?
4.3. Are there any settings that are used to launch docker containers or
shell out any commands, etc?

5. HA

5.1. Are there provisions for HA?
5.2. Are we leveraging the existing HA capabilities in HDFS?
5.3. Is Storage Container Manager a SPOF?
5.4. I see HA listed in future work in the architecture doc - is this still
an open issue?
