Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

1. SDN, OpenFlow and the ONF
OpenFlow/Software-Defined Networking (SDN)
“OpenFlow/SDN is emerging as one of the most promising and
disruptive networking technologies of recent years. It has the potential
to enable network innovation and create choice, and thus help realize
new capabilities and address persistent problems with networking. It
also promises to give network operators more control of their
infrastructure, allowing customization and optimization, therefore
reducing overall capital and operational costs. “
Source: http://opennetsummit.org/why.html
2. OpenFlow – Started 2008 at Standford
• Enabling innovation on campus
• Standard way to control flow-tables in
commercial switches and routers
• Being deployed at Stanford
• Consider deploying it at your campus too
OpenFlow
(Or: “Why can’t I innovate
in my wiring closet?”)
The Stanford Clean Slate Program http://cleanslate.stanford.edu
8. #1 CLI Automation
“Expect is quickly becoming a part of
every UNIX user's toolbox. It allows you
to automate
Telnet, FTP, passwd, rlogin, and hundreds
of other applications that normally
require human interaction. Using Expect
to automate these applications will allow
you to speed up tasks and, in many
cases, solve new problems that you never
would have even considered before.”
9. #3 Netconf / SNMP
Formal protocols to configure
and monitor network devices.
• Often read only!
• Back to CLI for configuration!
10. #3 Dynamic Configuration
Complex Standards and Protocols
to adapt Network Behavior for
requested Services.
• Carrier Centric approach
• Based on AAA Protocols
(RADIUS, DIAMETER=)
11. Conclusion!
You always Configure existing
Functionality!
There is no common API to Program
the network functionality!
12. Program your Network!
With SDN/OpenFLow you get an API to
program the network behavior with your
language of choice!
Rule Action Stats
Packet + byte counters
1. Forward packet to port(s)
2. Encapsulate and forward to controller
3. Drop packet
4. Send to normal processing pipeline
Switch MAC MAC Eth VLAN IP IP IP TCP TCP
Port src dst type ID Src Dst Prot sport dport
13. #1 Cellubi m2m Network
• Production Network for
m2m Communication
• Overlay Network over
four 3G provider across
the globe
• Fine granular policy
control and 1:1 NAT
funtionality
14. #2 Distributed BRAS
• Proof of Concept implementation
• Distributed PPPoE Termination close to the
Edge of a Carrier FTTH Network
• Eliminates huge, central, costly BRAS
installations
• Multicast Replication point is pushed to the
edge for IPTV optimisation
17. Classic Network Switch
• Static control path (static configuration)
VLANs, AAA, Filter, L3 Forwarding specified in
configuration
• Limited matching in forwarding
decision, mostly only things like MAC, VLAN
and/or QoS tags
• Once a forwarding decision has been made, it
can‘t be revised until it expires
18. Packet in Port Y:
SRC MAC: 00:11:11:11:11:11 Interessting Questions:
DST MAC: 00:55:55:55:55:55
• How can a MAC be moved to different
port (e.g a VM migrating to a new host)
Learn SRC MAC on Port Y • Can a switched be sliced into different
network partitions? E.g. Spanning Tree
with multiple VLANs
DST MAC on Port X ?
Forward on Port X ?
• How can ports isolated from each other
while still forming a single L2 domain?
e.g. Ethernet-to-the-Home and
Fibre-to-the-Home (FTTH) deployments
Flood on all Ports
19. Software Defined Network (SDN)
• Control Plane decoupled from Forwarding
Plane
• Network Control Plane accessible through API
• One Control instance can control multiple
forwarding instances
• Can match on everything in the packet and in
any combination (e.g. MAC+VLAN+IP+Port)
• Can alter packet during forwarding
20. Controller
• Controller can talk to multiple control plane instances
• Flexible matching
• MAC/Port learning over multiple instance
• Proactive moving MACs of to different ports
• Once forwarding decision has been made, forwarding
occurs in dedicate hardware at line speed
Control Path API
Data Path (specialized hardware)
21. What is OpenFlow (OF)?
• Protocol specification and reference
implementation of Software Defined Network
(SDN)
• OF Datapath imlementation for Linux Kernel
(replaces bridging) and FPGA board
• Used as basis in several commercial openflow
enabled switches
22. Typical OF message flow
packet_in <Port, Payload>
OF enabled datapath element
OF controller
flow_add <Match, Action>
flow_mod <Match, Action>
flow_removed <Match, Statistics>
23. OpenVSwitch
• Linux Kernel Datapath, Controller and
Configuration Database
• Can control OF enable hardware switch
• Used as software switch in Xen
• Supports for many standard management
interfaces and protocols (e.g.
NetFlow, sFlow, SPAN, RSPAN, CLI, LACP, 802.1
ag)
• Extensions over OpenFlow 1.0 Protocol
24. FlowER
• Modular platform for build OpenFlow
switches in Erlang
• Concentrate on the Switch and Flow
logic, Flower does the rest.
Provides:
• OpenFlow protocol, connection and data
abstraction
• Tools and algorithms typicaly needed for a
controller implementation

28. Theory of Operation
• flower_datapath module reads events from
network element
• flower_dispatcher forwards events to
interested parties (controller)
• controllers are chainable through events
• controllers implement full switch or parts of
it, generates new event processed by other
controllers or sends answer to datapath
29. flower_datapath
flower_datapath
• Abstracts the ‚real‘ OF enabled network
element
• Manages connection setup and keep-alive
• Controllers register for events from datapath
elements such as join, leave, packet-in
• Controllers messages to datapath elements
such as packet-out or flow-mod
31. Network Information Base (NIB)
NIB Library
Library for implementing:
• Network and network range based lookups
• Routing Tables
Nib = flower_nib4:new(),
Nib1 = flower_nib4:add({<<10,0,0,0>>, 8},
priv1, Nib),
{value, priv1} =
flower_nib4:lookup(<<10,10,10,10>>, Nib).
32. MAC Learning DB
MAC Learning DB
• MAC address learning and lookup table
• Addres expiry
• Filter for special MAC addresses
• MAC to string formater
33. Flow Decoder
Flow Decoder
• Raw packet decoded into all matchable fields:
– Src and Dst MAC Address
– VLAN Id
– L2 Protocol Type: IP, IPv6, ARP, LACP, ...
– IP Protocol Type: UDP, TCP, ...
– Src and Dst IP Address
– Src and Dst Port
– .....
34. De/encoder for network protocols
Packet De/Encoder
Decodes and build packet fragments for:
• IP, TCP and UDP header
• ICMP
• ARP
• more to come...
make_icmp({dest_unreach, pkt_filtered}, VLAN,
DstMAC, SrcMAC, IPSrc, IPDst, Payload).
36. Given a decoded flow construct a match on IP
Protocol and Src IP:
IP = <<127,0,0,1>>,
Flow = #flow{dl_type = ip,
nw_src = IP, nw_dst = IP},
encode_ofp_matchflow([{nw_src_mask,32}, dl_type],
Flow).
38. Further Work
• IPv6 support
• Replace the MAC learning database with
something much faster
• Improve and extend NIB Library
• Add load distribution in dispatcher
• …
• Extend Documentation ;-)
