  14. Serial Exemption Blanket Serial Exemption

  15. Substation Serial-Only Communications

  16. Non-Routable BCS • BES Cyber System and associated BES Cyber Assets are not dependent upon a routable protocol • A BES Cyber System may include only serial devices with no routable devices at all • End point devices (relays) are to be included within the V5 requirements and may be BES Cyber Assets or even BES Cyber System, even if no routable communications exist • Therefore, there are V5 requirements to be addressed (i.e. CIP-007-5)

  17. BCS with External Routable Connectivity • CIP-007-5 Applicable Requirements: • R1.2 Physical Ports • R2 – Patch Management • R3 – AV & Malicious code prevention • R4.1, R4.3, R4.4 – Logging • R5.2 – Default/Generic accounts • R5.4 – Change default passwords • R5.5 – Password complexity

  18. CIP-007-5 Asset Level Requirements • Most of CIP-007 can NOT be performed at a ‘system’ level but at the Cyber Asset level for the following assets: • BES Cyber Asset (BCA) • EACM • PACS • PCA • BCA groupings and BES Cyber Systems are permitted where indicated

  19. V5 Asset Level Requirements • PACS systems (CIP-006-5 Part 3.1) • Ports and Services (CIP-007-5 Part 1) • Patch Management (CIP-007-5 Part 2) • Security Event Monitoring (CIP-007-5 Part 4) • BES Cyber System and/or Cyber Asset (if supported) • System Access Control (CIP-007-5 Part 5) • local system accounts

  20. V5 Asset Level Requirements • Baseline requirement (CIP-010-1 Part 1.1) • Baseline change managements (CIP-010-1 Part 1.2 – 1.5) • Active monitoring -35 days (CIP-010-1 Part 2.1) • Cyber Vulnerability Assessment (CIP-010-1 Part 3.1, 3.2, 3.4) • Testing of new asset (CIP-010-1 Part 3.3) • System reuse or destruction (CIP-011-1 Part 2)

  21. CIP-007-5 Part 1.1 Asset level requirement

  22. Ports and Services • en.able, en.a.ble • Logical network accessible ports

  23. Ports and Services • Control required to be on the device itself or may be positioned inline (in a non-bypassable manner) • Host based firewalls, TCP_Wrappersor other means on the Cyber Asset to restrict access • Dynamic ports • Port ranges or services • 0-65535 • Blocking ports at the EAP does not substitute for the device level requirement • Know what ports are opened and give a reason for enabling service • Measures • Listening ports (netstat -boan/-pault) • Configuration files of host-based firewalls

  24. Tools/commands • Netstat: • Netstat -b -o -a -n > netstat_boan.txt • Netstat-p -a -u -l -t > netstat_pault.txt • NMAP scan results • Nmap -sT-sV –p T:0-65535 <IP_address> >>nmap_tcp.txt • Nmap –sU-sV –p U:0-65535 <IP_address> >> nmap_udp.txt • #show control-plane host open-ports • #show run all

  28. Router Ports/Services

  29. What We Expect [Sample only] SAMPLE FORMAT ONLY

  30. Question • Is it required to capture not only the need for a port to be open, but also the authorization request for the port to be opened? • CIP-010-1 Part 1.1 • "Develop a baseline configuration, individually or by group, which shall include the following items: • 1.1.4. Any logical network accessible ports;’ • need for a port to be open and not an actual authorization request for the port to be opened.

  31. Authorizations • CIP-010-1 Part 1.2 • "Authorize and document changes that deviate from the existing baseline configuration.” • Measure: • A change request record and associated electronic authorization (performed by the individual or group with the authority to authorize the change) in a change management system for each change; or"

  32. CIP-007-5 / CIP-010-1 Relationship • CIP-010-1 baseline configuration requirements • CIP-010-1 Part 1.1.4 • Develop a baseline configuration of any logical network accessible ports • Documented list of enabled ports • CIP-007-5 Part 1.1 is concerned only with the enabling of needed ports • Performance (CIP-007-5) versus documentation (CIP-010-1)

  33. Double Jeopardy? • Failing to maintain the baseline configuration and failing to disable unnecessary ports are two different requirement violations • CIP-007-5 Part 1.1 refers to listings of ports as evidence, but that evidence could be the same evidence required for CIP-010-1. • Utilizing a single piece of evidence for proof of compliance with two different requirements is not double jeopardy

  34. R1.1 Issues & Pitfalls • Accurate enablement of required ports, services and port ranges • Understanding critical data flows and communications within ESP and EAPs • Logical ports include 65535 TCP& 65535 UDP ports • Managing changes of both logical and physical ports • Initial identification of physical port usage and controls – port use mapping • VA, approved baselines, and implemented logical ports and services should always agree (CIP-010-1 and CIP-007-5) • Focus on EAPs inward to ESP Cyber Systems and Cyber Assets

  35. CIP-007-5 Part 1.2 Asset level requirement

  36. CIP-007-5 Part 1.2 Asset level requirement

  37. CIP-007-3  CIP-007-5 Change

  38. Configuration Ports • Change Bios • Upgrade Firmware • Set Baseline Configuration • Build-out devices that have components (like servers) • Perform a variety of Administrative functions • Perform emergency repair or failure recovery when no other port is accessible http://www.tditechnologies.com/whitepaper-nerc-cip-007-5-r1

  39. Part 1.2 Physical Ports • physical I/O ports • Network • Serial • USB ports external to the device casing

  40. Part 1.2 Physical Ports • All ports should be either secured or disabled • Ports can be protected via a common method not required to be per port • “Protect against the use” • Requirement is not to be a 100% preventative control • Last measure in a defense in depth layered control environment to make personnel think before attaching to a BES Cyber System in the highest risk areas

  41. Guidelines • Disabling all unneeded physical ports within the Cyber Asset’s configuration • Prominent signage, tamper tape, or other means of conveying that the ports should not be used without proper authorization • Physical port obstruction through removable locks

  42. Port Locks http://www.blackbox.com/resource/genPDF/Brochures/LockPORT-Brochure.pdf

  43. Physical Access to Ports http://www.supernap.com/supernap-gallery-fullscreen/

  44. Question • Would a Cyber Asset locked in a cage meet this requirement? • Answer • No, the required control needs to be applied on the Cyber Asset level

  45. Part 1.2 Physical Ports • Documented approach to ensure unused physical ports are controlled (identify controls in place) • Controls in place for ensuring that attempts of physical port usage are identified • Think before you plug anything into one of these systems • Controls: 802.1x, physical plugs, port block, signage • Physical port usage documentation – know what is in use versus existing ports not required • Site tours may validate physical port documentation

  46. Physical Ports and Applicable Systems • A routable device with all of its physical network ports blocked which would have otherwise been identified as routable device, now cannot route. • The ability to communicate outside of itself is not a determining factor as to whether a Cyber Asset is or is not a BES Cyber Asset or BES Cyber System • The Cyber Asset’s function as it pertains to BES reliability determines system identification

  47. CIP-007-5 Part 2.1 Asset level requirement

  48. CIP-007-3  CIP-007-5 Change

  49. Part 2.1 Patch Management Process • Patch management documented process • List of sources monitored for BES Cyber Systems and/or BES Cyber Assets • List of Cyber Assets and software used for patch management • Watching and being aware of vulnerabilities within BES Cyber Systems, whether they are routably connected or not, and mitigating those vulnerabilities • Applicable to BES Cyber Systems that are accessible remotely as well as standalone systems

  50. Part 2.1 Tracking • Requirement allows entities to focus on a monthly ‘batch’ cycle of patches rather than tracking timelines for every individual patch • Tracking can be on a monthly basis for all patches released that month rather than on an individual patch basis • Decision to install/upgrade security patch left to the Responsible Entity to make based on the specific circumstances
