You just had sat down with a real page turner when you got the call. Campbell
from IT went into the office after receiving a couple calls from staff who were not
able to access e-mail or files from the file share.
Campbell says that the e-mail server, file server and a number of other key
servers are inaccessible. All he can see is a text file that contains a cryptic note
about e-mailing a protonmail address to get access to the data.
Campbell asks you what to do.

5. Events, incidents and
“breaches”

6. o A security event is a possible problem that
should be assessed
o An security incident is a confirmed problem
that needs to be managed through the
incident response process
• Cyber attack
• A misconfiguration
• An errant communication
o A “breach” is a legal concept that relates to
unauthorized access to information or loss,
theft…
Learn and use this helpful nomenclature
Events, incidents and “breaches”

7. The incident response
process

8. o Quickly re-establish baseline data security
• Confidentiality (stop leakage and exposure)
• Integrity (get bad actors out)
• Availability (restore services)
o To appropriately manage the legal risks of
the incident, especially those arising out of
data exposure
o To foster leaning and security program
improvement

9. o Stop the incident from getting worse
o May involve
• Disconnecting from the internet
• Fixing a misconfiguration
• Changing a password to a compromised
account
o Steps are taken immediately with available
resources
o Should not entail overwriting data to restore
services, which can cause loss of evidence
Step 1a – Contain (first few hours)
The incident response process
9

10. o Don’t
• Call the police
• Call the privacy commissioner
• Call the board chair
o Do
• Consult a lawyer
• Who will retain one or more experts to help
Step 1b – Get help (first few hours)
The incident response process
10

11. o In a malware event this can become difficult
quickly without expert guidance, with
evidence being destroyed and more
information being stolen
o Can involve
• Negotiating a ransom payment and the
retrieval of decryption keys
• Restoration coaching by expert
• Installation of endpoint mentoring software
tools to watch for signs of persistence
Step 2 – Restore and secure (days two to four)
The incident response process
11

12. o Starts with the gathering of digital evidence
o Evidence is analyzed to answer two key
questions:
• How did this happen?
• What data was exposed and how?
o Not search for things you want to find, but
there will often be a duty to conduct a duly
diligent investigation
o If the expert determines there has been no
exposure, you will rest heavily on that
conclusion in taking no father action
Step 3a – Investigate (days four to…)
The incident response process
12

13. o Mitigate all the harms and potential harms arising
out of the incident, including reputational harms and
harms to people
o We do this primarily by communication
• Media releases
• Notification to affected individuals
• Credit monitoring offerings
• Reporting to law enforcement or sharing threat
information
o Keys to success
• Timing – How fast is your “clock speed”?
• Accuracy – Don’t misrepresent or take risks on making
affirmative statements when you don’t know.
Step 3b – Mitigate (days four to…)
The incident response process
13

14. o Investigation is complete
o Mitigation steps taken
o Final remedial plan developed with an
implementation plan
• Take the “how” from the investigation report…
• …and apply the “5 whys”
• Develop a meaningful list of changes to
address the root and next level causes
o Assess your incident response process too!
Step 4 – Learn and move on

15. Incident response tips

16. o Use a small cross-functional team with the
necessary experts who keeps the matter
confidential
o All communications outside the zone of
confidence are approved
o If a lawyer leads, communications to/from the
lawyer will be privileged
• Lawyer instructs experts for well-defined
purpose that links to privilege
• Substantive issues all brought to the lawyer for
consideration
• Communications between team members who
are not lawyers are limited to what is factual and
administrative
Internal communication and privilege
Incident response tips
16

17. o Don’t say “we value your privacy.” Show it.
o Consider apologizing, but not profusely
o Convey the facts that will be meaningful to
those affected
• What was exposed
• For how long
• To whom
o Include a list of meaningful remedial measures
o Beware of legal requirements for what must go
in a notification letter
Notifying and communicating
Incident response tips
17

18. o Notification is generally based on exposure of
personal information, not a security incident alone
• Though an incident alone may lead you to engage in
the sharing of threat information
o There may be a statutory duty to notify (and report)
o Or there may be another reason to notify
• There’s a real potential for significant harm
• The incident is known
• The incident is likely to become known
o Many organizations notify reactively, too quickly and
without good reason
When to notify

19. The incident response
plan

20. o An “IRP” applies to all forms of security
incidents
o It is premised on the idea that incidents will
occur and can be anticipated
o It structures the response to save time and
support optimal decision-making
• Identifies the key processes and decisions
• Puts information at hand
• Provides decision-making authority
Your response process should be embedded in a PLAN
The incident response plan
20

21. o Frame out the process
o Identify responsibilities
o Append
• Contact information for 24/7 contact
• Pre-retained experts
• Playbooks for certain expected scenarios
o Create playbooks by running scenario
based exercises
