IN THE BEGINNING

COMPLIANCE • 375 PAGE DOCUMENT• MINIMUM BASELINE: 87 RATIONALIZED

CONTROLS• RISK BASED ON IMPACT & LIKELIHOOD

SOFTWARE DEVELOPER• OK – HOW DOES THAT APPLY TO WHAT I

DO?

EVOLUTION

FULL STACK VULNERABILITIES

• API KEY EXPOSURE -> 8

HRS• DEFAULT

CONFIGS -> 24 HRS

• SECURITY GROUPS -> 24

HRS • ESCALATION OF

PRIVS -> 5 DAYS

• KNOWN VULN -> 8 HRS

SECURITY AS CODE

• INFRASTRUCTURE -> TEMPLATES & RECIPES• FIREWALLS -> SECURITY GROUPS• ACCESS CONTROLS -> IAM USERS AND POLICIES• IDS -> HOST AGENTS & RESOURCE TESTING• LOGGING -> API & INSTANCE LOGGING• FORENSICS -> SNAPSHOTS & API PROFILE• VULNERABILITY SCORES -> GRADES

SOFTWARE DEFINED UPS & DOWNS

PLUS• FAR MORE DATA THAT SIMPLY NEEDS TO BE HARNESSED• FASTER DETECTION, CONTAINMENT & REMEDIATION• ABILITY TO REFRESH STACKS TO AVOID CRITICAL ISSUES

MINUS• MUCH EASIER TO MAKE CRITICAL MISTAKES• MOST EVENTS COME FROM DEFAULT IMPLEMENTATIONS• HUGE DATA MAKES EVERYTHING HARDER

• BUILD SECURE COMPONENTS FOR INCLUSION

• MAKE RESOURCE LEVEL CHANGES AND DISSEMINATE TO TEAMS

• APPLY LESSONS FROM SECURITY OPERATIONS & INCIDENT RESPONSE TO BASELINE COMPONENTS

• MANAGE FOR DRIFT BY BUILDING OUT DIFF TOOLS

RESOURCE TESTING & VALIDATION

• RESOURCE AND COMPONENT TESTING IMPROVES RUGGEDNESS OF SOFTWARE DURING INTEGRATION

• TOOLS CAN BE CALLED FROM CONTINUOUS INTEGRATION & CONTINUOUS DEPLOYMENT PIPELINE

• RESPONDERS CAN TRIGGER INLINE TESTING TO IDENTIFY VULNERABILITIES UNDER ATTACK

• ATTACKS ARE DEFINED IN GHERKIN• API TO REQUEST TESTING BY TYPE

LESSONS

TABLE STAKES

• GO NATIVE, WHEN POSSIBLE• MFA -> TABLE-STAKES, USE IT.• PRIVILEGED ACCESS -> USE LEAST PRIVILEGE, ASSUMEROLE WHEN

NEEDED• SECURITY GROUPS -> LIMIT ACCESS AND SCOPE TO SPECIFIC NEEDS• DEPLOYMENT AUTOMATION -> OVER-PRIVILEGED, UNDER-SECURED• RE-STACK OFTEN -> CRITICAL VULNERABILITIES OCCUR ON AVERAGE EVERY 10

DAYS.• USE ENCRYPTION OPTIONS

DON’T BE AN ALL-*

DON’T EMBED SECRETS…

…DON’T PUT ANY API KEYS, SSH PRIVATE KEYS, OR SSL PRIVATE KEYS IN :• CLOUDFORMATION, • USER-DATA, • GIT, • OR ANYWHERE ELSE THAT CAN’T KEEP A SECRET,

SECRET

DON’T OVER-SHARE…

WE DON’T WANT TO KNOW YOUR SECRETS…

…AND YOU DON’T WANT YOUR SECRETS GETTING OUT.
