Business continuity and disaster recovery are not the same but complement each other. Planning on BCP and DRP is necessary for all business. This slide contains information on how to achieve and maintain them.
2. Objectives
ī§ Running a business continuity and
disaster recovery planning project
ī§ Developing business continuity
and disaster recovery plans
ī§ Testing business continuity and
disaster recovery plans
ī§ Training users
ī§ Maintaining business continuity
and disaster recovery plans
4. What Is a Disaster
Any natural or man-made event that disrupts
the operations of a business
in such a significant way that a considerable and
coordinated effort is required to achieve a
recovery.
5. Natural Disasters
ī§ Geological:
earthquakes, volcanoes, tsunamis, landslides,
and sinkholes
ī§ Meteorological: hurricanes, tornados, wind
storms, hail, ice storms, snow
storms, rainstorms, and lightning
ī§ Other: avalanches, fires, floods, meteors and
meteorites, and solar storms
ī§ Health: widespread illnesses, quarantines, and
pandemics
7. Man-made Disasters
ī§ Labor: strikes, walkouts, and slow-downs that
disrupt services and supplies
ī§ Social-political:
war, terrorism, sabotage, vandalism, civil
unrest, protests, demonstrations, cyber
attacks, and blockades
ī§ Materials: fires, hazardous materials spills
ī§ Utilities: power failures, communications
outages, water supply shortages, fuel
shortages, and radioactive fallout from power
8. How Disasters Affect
Businesses
ī§ Direct damage to facilities and equipment
ī§ Transportation infrastructure damage
ī
Delays deliveries, supplies, customers, employees
going to work
ī§ Communications outages
ī§ Utilities outages
9. How BCP and DRP
Support Security
ī§ Security pillars: C-I-A
ī
ī
ī
Confidentiality
Integrity
Availability
ī§ BCP and DRP directly support availability
10. BCP and DRP
Differences and Similarities
ī§ BCP
ī
ī
ī
Activities required to
ensure the
continuation of critical
business processes in
an organization
Alternate
personnel, equipment
, and facilities
Often includes non-IT
aspects of business
ī§ DRP
ī
ī
Assessment, salvage, r
epair, and eventual
restoration of
damaged facilities and
systems
Often focuses on IT
systems
11. Industry Standards Supporting

ī
ī
ī
ī

Contingency plans that provide [near]
continuous operation of critical
business processes

21. Survey In-scope
Business Processes
ī§ Develop interview / intake template
ī§ Interview a rep from each department
ī
ī
Identify all important processes
Identify dependencies on
systems, people, equipment
ī§ Collate data into database or spreadsheets
ī
Gives a big picture, all-company view
22. Performing a Business
Impact Assessment
ī§ Survey critical processes
ī§ Perform risk analyses and threat assessment
ī§ Determine Maximum Tolerable Downtime
(MTD)
ī§ Establish key recovery targets
23. Threat and Risk Analysis
ī§ Identify threats, vulnerabilities, risks, for each
key process
ī
ī
Rank according to probability, impact, cost
Identify mitigating controls
24. Determine Maximum
Tolerable Downtime (MTD)
ī§ For each business process
ī§ Identify the maximum time that each business
process can be inoperative before significant
damage or long-term viability is threatened
ī§ Probably an educated guess for many
processes
ī§ Obtain senior management input to validate
data
ī§ Publish into the same database / spreadsheet
listing all business processes
25. Develop Statements of Impact
ī§ For each process, describe the impact
on the rest of the organization if the process is
incapacitated
ī§ Examples
ī
ī
ī
Inability to process payments
Inability to produce invoices
Inability to access customer data for support
purposes
26. Record Other Key Metrics
ī§ Examples
ī
ī
ī
Cost to operate the process
Cost of process downtime
Profit derived from the process
ī§ Useful for upcoming Criticality Analysis
27. Ascertain Current Continuity
and Recovery Capabilities
ī§ For each business process
ī
ī
ī
Identify documented continuity capabilities
Identify documented recovery capabilities
Identify undocumented capabilities
ī§ What if the disaster happened tomorrow
28. Develop Key Recovery Targets
ī§ Recovery time objective (RTO)
ī
Period of time from disaster onset to
resumption of business process
ī§ Recovery point objective (RPO)
ī
ī
Maximum period of data loss from onset
of disaster counting backwards
Amount of work that will have to be done over
ī§ Obtain senior management buyoff on RTO/RPO

ranking in the criticality analysis)
ī
ī
ī
ī

Do mitigating controls follow best / common
practices
34. Select Recovery Team
Members
ī§ Selection criteria
ī
ī
ī
ī
ī
Location of residence, relative to work
and other key locations
Skills and experience (determines effectiveness)
Ability and willingness to respond
Health and family (determines probability to
serve)
Identify backups
ī§ Other team members, external resources
35. Emergency Response
ī§ Personnel safety: includes first-aid, searching
for personnel, etc.
ī§ Evacuation: evacuation procedures to prevent
any hazard to workers.
ī§ Asset protection: includes buildings, vehicles,
and equipment.
36. Emergency Response (cont.)
ī§ Damage assessment: this could involve
outside structural engineers to assess damage
to buildings and equipment.
ī§ Emergency notification: response team
communication, and keeping management
and organization staff informed.
37. Damage Assessment and
Salvage
ī§ Determine damage to
buildings, equipment, utilities
ī
ī
Requires inside experts
Usually requires outside experts
ī§ Civil engineers to inspect buildings
ī§ Government building inspectors
ī§ Salvage
ī
ī
Identify working and salvageable assets
Cannibalize for parts or other uses
38. Notification
ī§ Many parties need to know the condition of
the organization
ī
Employees, suppliers, customers, regulators,
authorities, shareholders, community
ī§ Methods of communication
ī
ī
Telephone call trees, web site, signage, media
Alternate means of communication must be
identified
39. Personnel Safety
ī§ The number one concern in any disaster
response operation
ī
ī
ī
ī
Emergency evacuation
Accounting for all personnel
Administering first-aid
Emergency supplies
ī§ Water, food, blankets, shelters
ī§ On-site employees could be stranded for
several days
40. Communications
ī§ Communications essential during emergency
operations
ī§ Considerations
ī
Avoid common infrastructure
ī§ Don't have emergency communications through the
same wires as normal communications
ī
ī
ī
ī
Diversify mobile services
Consider two-way radios
Consider satellite phones
Consider amateur radio
41. Public Utilities and
Infrastructure
ī§ Often interrupted during a disaster
ī
ī
ī
ī
ī
Electricity: UPS (Uninterruptible Power
Supply), generator
Water: building could be closed if no
water is available for fire suppression
Natural gas: heating
Wastewater: if disabled, building could be closed
Steam heat

Assurance of data recovery
ī§ Server clusters
ī
ī
Improved availability
Geographic clusters: members far apart
ī§ Data replication

remote places
48. Testing Business Continuity
and Disaster Recovery Plans
ī§ Five levels of testing
ī
ī
ī
ī
ī
Document review
Walkthrough
Simulation
Parallel test
Cutover test
49. Document Review
ī§ Review of recovery, operations, resumption
plans and procedures
ī§ Performed by individuals
ī§ Provide feedback to document owners
50. Walkthrough
ī§ Performed by teams
ī§ Group discussion of recovery, operations,
resumption plans and procedures
ī§ Brainstorming and discussion brings out new
issues, ideas
ī§ Provide feedback to document owners
51. Simulation
ī§ Walkthrough of recovery, operations,
resumption plans and procedures in a scripted
âcase studyâ or âscenarioâ
ī§ Performed by teams
ī§ Places participants in a mental disaster setting
that helps them discern real issues more
easily
52. Parallel Test
ī§ Full or partial workload is applied to recovery
systems
ī§ Performed by teams
ī§ Tests actual system readiness and accuracy of
procedures
ī§ Production systems continue to operate and
support actual business processes
53. Cutover Test
ī§ Production systems are shut down or
disconnected; recovery systems assume full
actual workload
ī§ Risk of interrupting real business
ī§ Gives confidence in DR (Disaster Recovery)
system if it works
55. Maintaining Business Continuity
and Disaster Recovery Plans
ī§ Events that necessitate review and
modification of DRP and BCP procedures:
ī
ī
ī
ī
ī
ī
