OVAL for Inter-networking Devices
The OVAL specification currently supports a diverse set of
platforms. We see Windows and a variety of UNIX operating systems
supported of which there is only one Inter-networking platform. Inter-
networking devices are routers and switches that connect the Internet.
Currently Cisco is only vendor and platform that is represented in the
area of inter-networking devices. In this session we propose a new
platform to be supported by the OVAL specification. The session will
cover new schema, content and tool (jOVALdi) associated with the new
platform. The session will also compare similarities between the Cisco
IOS schema and the new platform schema.

jOVAL SecPod Apex Assurance
 Collaboration with alignment of interests.
 Apex Assurance – Juniper is a good customer to Apex. This was a
worth while effort to get Juniper on the SCAP map and also contribute
to the community.
 jOVAL – Natural to further extend the tool to other networking
platforms.
 SecPod – Further expand in content capabilities.
 We encourage others to collaborate on common interests.


Project Martini Goals
 Get Juniper Junos supported in OVAL
 Proof of concept
 “rough consensus and running code”
– Tool – jOVAL(jovaldi, Xpert)

– Content OVAL, XCCDF, CCE, CPE

– Junos OVAL schema
 Acceptance of prototype concept into official OVAL release
 Think big but keep it simple


Current list platforms supported on OVAL

Candidate Platform


Ingredients to making this work
 Specification support for Junos within OVAL
 Content – STIG, SCAP (OVAL, CPE, CCE, XCCDF)
– SCAP 1.2 data streams
 Tool – jOVAL
– Xpert

– Jovaldi


Juniper Junos OVAL Schema

Junos definition schema

Junos system
characteristics


OVAL tests (Inter-networking devices)


DISA Network Infrastructure STIG
 Cisco IOS specific checklists (XCCDF)
 Juniper Junos specific checklists (XCCDF)


Juniper Junos Content – SCAP 1.2 data stream
• sp- junos-cce-xccdf.xml
• sp-junos-cce-oval.xml
• sp-junos-cpe-oval.xml
• sp-junos-cpe-dictionary.xml

OVAL CCE

Junos

XCCDF CPE


DISA STIG NET0400 test
 STIG ID NET0400 – Interior routing protocols are not authenticated
 Sample Junos CCE
 Junos command line interface (CLI) output
 Curly brace CLI example
[edit protocols ospf]
ospf {
area 0.0.0.0 {
interface em0.0 {
authentication {
md5 1 key "$9$FYPx3tOylMWxdWLkPfQCAxNdV4Z.PQz6Az3vLXN2g69AtIcWLN”;
}
}
}
}

 set CLI example
set protocols ospf area 0.0.0.0 interface ge-0/0/0.0 authentication md5 1 key
"$9$FYPx3tOylMWxdWLkPfQCAxNdV4Z.PQz6Az3vLXN2g69AtIcWLN"


DISA STIG NET0340 test
 STIG ID NET0340 – Login banner is non-existent or not DOD
approved
 Sample Junos CCE
 Simple check
 Variable
 Junos command line interface (CLI) output
 set CLI example
set system login message “test banner page”

Demo Content
 OVAL JunOS schema
 OVAL definition
 XCCDF – based on DISA STIG
 CPE
 CCE


Challenges and Lessons Learned
 Lack of inter-networking vendors participation in the specifications
 The focus of the specifications on Windows and Linux Operating
Systems. Slow adoption to other platforms.
 Incentives to adopt

Lack of support for Inter-networking devices
 OVAL board members: Tool Vendors, OS Vendors, Others
 No Incentives?
 Is there demand for (OVAL) routers and switches? Yes
