Security function benefits from DevSecOps
#GISEC 2020 @FintoNT 8
Rapid Business value delivery Rapid user feedback Scalable and Auto SizingFast to Market, Market Edge
1. Shift Left – Security is baked-in in early stages
2. Products have inbuilt security controls – Robust , Secure products to market
3. Less vulnerable product – Build test will fail automatically while developer “commit” (save) the code
4. Security is everyone's responsibility – Better collaboration among the whole app development chain
5. High Returns on security Investment – Early detection and remediation save effort and time

9.
Developers benefits from DevSecOps
#GISEC 2020 @FintoNT 9
Rapid Business value delivery Rapid user feedback Scalable and Auto SizingFast to Market, Market Edge
1. Instant feedback - Developers getting faster feed back on security tests and use cases (~5 mints)
2. No more surprises from Security reports – Security is a part of pipeline and transparent to all
3. Better Security awareness and collaboration – One Team + One agenda + One delivery

10.
Operational benefits from DevSecOps
#GISEC 2020 @FintoNT 10
Rapid Business value delivery Rapid user feedback Scalable and Auto SizingFast to Market, Market Edge
1. Early detection and prevention systems – Security threats and Incidents can be identified early stages of pipeline
2. Easy to fix production issues– Isolate it with out production impact
3. Expectations are more clear and simple – Compliance , Hardening etc are established in early stages as “user
stories”
4. Automation reduces Ops team effort from security maintenance – repeatable remediation steps can be automated

11.
Key constraints
#GISEC 2020 @FintoNT 11
1. Asset/Service Inventory, tracking and billing – Orphan and testing containers and systems
2. Identity and Access Management - Hardcoded and decentralized credentials
3. High Cost of Enterprise Tools & limitations – Language specific , Cloud licensing need attention
4. Skill shortage on DevSecOps – Market adoption still in early stages
5. Adoption of new mindset and tools – Definition of perimeter changes and it is no more traditional

Methodologies and Culture
#GISEC 2020 @FintoNT 13
1. Embrace Developers with right tools and advises, find Security tools that Developers will actually use
2. Security needs to adopt Agile – Sprint models and process that’s fit for new environments. Automation is key.
3. Identify and eliminate the Risk early as possible in the workflow with relevant prioritizations and trade-offs

14.
Peoples and Skills
#GISEC 2020 @FintoNT 14
Zero Trust
3. Collaborate on Problem solving, avoid blame game
1. Build Personal Trust and break silos
2. Encourage Security mindsets and Security champions with relevant trainings and incentive programs

15.
Tools and Technologies
#GISEC 2020 @FintoNT 15
3. Traditional Security tools often do not work with new environment
2. Traditional Security solutions are logically valuable, but need to adopt with new environment
1. Adopt new programable tools, which Developers really use, Security team role is advisory and enablers

16.
Maturity Assessment

Key Takeaways
Technology and Tools Process and Methodologies People and Skills
#GISEC 2020 @FintoNT 17
DevSecOps = New Culture + New Skills + Automation
Bake in Security into DevOps flow,
do not try to bolt security later
Security control must be
programable and automated
wherever possible
Keep an eye on simpler and better
programable options
Use tools and methods that
developer team actually use
Adopt Agile and lean methods
Involve security as early as possible
in the workflow and best to do at
design & planning phase
Fix by priorities, do not attempt to
fix it all
DevSecOps feedback process must
be smooth and governed
Metric and KPI needs to relevant
and easy to generate
Build personal relations and trust
Break silos; do not isolate
Identify and nurture “security
champions” in each team
Focus on problem and solution; Do
not blame the person or team
Conduct short and repeatable
training sessions and training
