 Review company standards, policies, and procedures.
 Consider most common attack vectors.
 Interview development teams, business professionals, or
others.
 Evaluate system code or test security product functionality.
Cybersecurity AssessmentsMinimum.
Not great.
Also, cheap.

16.  Find and exploit system vulnerabilities.
 Sort of like a hacker, but not really
 Much more limited time frame
 Limited by scope (provided by customer)
 Network, internal, cloud, deployments, applications, products
 Some access to expose vulnerabilities
 Objective: Coverage or target?
 Approaches: scanning, reverse-engineering, social engineering
Penetration Tests

21. Malware on
infected
machines scans
for other
machines to
attack on the
Internet and
within internal
networks.
Zero Trust!

22. People Many security
incidents involve
human actions!

23.  Verify it’s a security problem.
 Capture evidence in a way that proves no one tampered with
it.
 Handle evidence in a secure manner (chain of custody).
 Contain the malware to prevent spread.
 Potentially observe it or use the copy for analysis.
 Remove it from systems – completely!
 Report and learn from the incident.

24. Q: How did our systems get breached?
A: An attacker got ransomware onto our systems.
Q: How did the attacker get ransomware onto our systems?
A: They got onto one of the machines in our network.
Q: How did they get onto the machine?
A: General: Evil link in email, vulnerability, misconfiguration.
Q: What was the link? What was the vulnerability?
A: Specific: The actual link, CVE, IP address, port, software.

 Reduce risk of a data breach and potential damage.
 Attack vectors: The different attacks available on your
systems.
 Attack surface: The amount of exposure available to
attack.
 Blast Radius: How much damage unauthorized access
can cause.
Key to security

29. 1. Immutable software deliverables in Solar Winds
deployments.
2. Identification of C2 network traffic by affected customers.
3. Least-privilege for credentials on infected systems.
4. Just-in-time and conditional access for high-risk actions.
What could have prevented the attack?
Security architecture
Security operations or analyst

30.  Security has a lot of rules and lists!
 Where should you start?
 How do attackers get in?
1. Abstract the details to core principles.
2. Prioritize fixing highest risk findings.
3. Avoid over-analysis.
4. Avoid repeat problems.

31. The Concept of Abstraction
Less to manage.

32. The same set of
principles can stop or
limit damage for a
myriad of attacks!

33. 20 cybersecurity questions
 Key factors that drive data breaches.
 Learn fundamental cybersecurity.
 Study how attacks work.
 Abstract common attack vectors.
 Understand what stops them.
 Reduce the chances you give attackers.
 Create metrics that make a difference.
 Automated reporting + Manual analysis.

34. 20 questions to ask your security team
How many CVEs? Developer security training? Network, data, app?
Percent of systems exposed to the
Internet?
What are our security policies?
Data exposed to Internet? Who generates most exceptions? Why?
Total attack paths on our network? Security checks built into deployment systems?
Potential damage if credentials stolen? Are we vetting our vendors? How?
Percentage of accounts with MFA? Proof that our security solutions provide value?
Percentage data encrypted when stored? Do we have an incident handling team or plan?
Percentage of network traffic encrypted? What percent activities can be and are
automated?
Findings from pentests and assessments? What is the overall risk level? Getting better?
Can we restore from backups? Tested? How is the threat landscape changing?

be solved by
automation.
Analysis

40.  Executives
 Developers
 Marketing
 Human resources
 Salespeople
 Interns!
 Contractors
 Third-party vendors
Everyone needs security awareness!
All it takes is one mistake…

41.  People need to understand why rules exist.
 Communication is critical.
 Email and videos not that effective.
 Iterative fixes.
 Test before blocking.
 Get executive support.
The organization still needs to function
