Open-source components are prevalent in approximately 97% of modern applications and dominate anywhere between 60-80% of their codebases. This is hardly surprising given how integrating open source accelerates software development and enables organizations to keep up with today's frantic release pace and standards of constantly supplying new features and improvements. However, taking into consideration the fact that recent years have seen an upsurge in reported open-source vulnerabilities, whose details and exploits are publicly available, it's no wonder that organizations are increasingly directing focus towards ensuring that their open-source components are securely integrated into their software. Join Guy Bar-Gil, Product Manager at WhiteSource, as he discusses: The four layers of open-source security; How to integrate continuous security into your SDLC; Best practices for organizations to own and execute the security process.

1The Equifax Breach

5. • Consumer credit reporting agency
• Equifax collects and aggregates information
• 800M+ individual consumers
• 88M+ businesses
• Publicly traded (NYSE), 9.5K+ employees, $3.14B in revenues (2016)

6. Apache Struts
• Open-source framework, for creating
Java web applications.
• CVE-2017-5638 allows remote code
execution through the web
applications.

The Equifax Breach – A Timeline
March 9th:
• CVE-2017-5638 was published.
• The Apache Software Foundation released a patch for the vulnerability.
• Equifax administrators were told to apply the patch to any affected systems.
March 10th: Hackers gained access to Equifax’s systems.
March 15th: Equifax's IT department ran a series of scans to identify unpatched systems.
May 13th: Hackers begin exfiltrating data.
July 29th: Equifax renews their expired public-key certificate
September 7th: Equifax publicized the breach

8. Incident Aftermath

SmallComp’s M&A

11. SmallComp’s M&A
• SmallComp required to do an open-
source audit
• Each component comes with certain
terms
• Found a dependency licensed under
AGPL
11

12. $4M Dollars in Escrow
12
• Terms of the escrow:
• Remove any trace of AGPL from the
software.
• 80% of customers must deploy the
updated software to production.
• Two year timeframe.
• Development/deployment-related costs
taken from the escrow.

13. 13
Solving The Problem
Isn’t So Easy
Two main obstacles:
• Development + QA time is 1 year for 1 person
• SmallComp’s customers are hospitals, where
solutions are often manually deployed and
technicians are required to train staff

14. They Did It!
SmallComp was able to fulfill the terms of the escrow
after 1 year and 8 months!

How Do We Avoid This Situation?

3Staying Secure

17. Step 1:
Create Transparency
• Transparency is the baseline to everything
• How can you detect and solve issues in your open-
source components if you have no idea what they
are?
• Understand exactly what you’re using:
• Direct Dependencies
• Transitive Dependencies
• Source files

Lots of jars
?

19. 19
Lots of jars, but lots more java beans
?

20. Step 2:
Detect Potential Issues
• Match your components to the most
comprehensive DB possible:
• Published CVEs
• Vulnerabilities published in security advisories
• Vulnerabilities detected by research teams
• Thorough license detection
20

21. Step 3: Prioritize
How would you prioritize your vulnerabilities?
21

22. Step 3: Prioritize
• Prioritize by:
• Business risk
• Exploitability
• Severity
• Effectiveness
• Availability of fixes
22

23. 23
Vulnerabilities Prioritization

24. 24
After testing 2,000 Java
applications, WhiteSource
found that 85% of all
detected vulnerabilities
were deemed ineffective.

25. Step 4:
Execution
• Understand the best path to remediation
• Upgrade the component’s version?
• Change the component?
• Set up an external defense?

Implementation!

28. Step 1 : Creating Transparency
Identify the processes in your software development lifecycle (SDLC)

29. Step 2: Detect
• Where you want to implement security checks
• Where you can automate

Step 3: Prioritize
• Act on early -> Shifting left
• Avoid allowing vulnerable components
reach deployment
• How much does it cost?

35. 35
Detect Issues As Early As Possible

36. Step 4: Execution
Who’s responsibility is it?
• Security team:
• Setting policies
• Educating developers
• Development team:
• Execution

37. 37
Developers need robust tools,
that fit into their workflows

38. 38
Educate
About the basics of open-source security & compliance
Empower Teams
By providing them the right tools
Enable Success
By creating a shared mission
