Why engage managed services?
• I don’t have the bodies
• Painful to do 24x7x365
• Brains onsite, muscles offsite
• Cannot scale team with business
• I can’t find or retain the skills
• I want the Network Effects
• I need it now!

Meet Bob
Snapshot• Anxious Account Manager @ Global MSSP• Personally manages dozens of customers• Incented on SLA adherence and customer sat• Competent but over-stretched
Bob’s Complaints• “I’m still waiting for XYZ requirements”• “You don’t show up to meetings”• “You only talk to me when it’s an emergency”• “I need your attention”
Meet Alice
• Snapshot• Crafty CISO of Major Retailer• Small team of engineers• Budget increasing but no headcount• Multiple “strategic partners”• Has little influence over business units
• Alice’s Complaints• “You use to ask me how I’m doing”• “You don’t show me things anymore”• “Why do I have to ask for everything? You should know!”• “You use to give me more attention”
What’s the nail? (Blind Spots)
Bob the MSSP
• Incented to ‘set and forget’
• Wants to get paid quickly – rush onboarding
• Demands requirements but isn’t proactive
• Missing Alice’s business context
• Meet SLA and that’s it
Alice the Client• Minimal organization influence
• Outdated technology with default configs
• Doesn’t have access to stuff herself
• Doesn’t know what do to with an escalation

What logs to collect (Initially)?
Low Hanging Fruit• Firewall• Active Directory• IPS• Critical Servers• Anti-Virus
Possible Added Value• Application Logs• DB Logs• Security Devices (URL, DLP, WAF, Endpoint)

Big Data Analytics Improving Context
Traditional SIEM• Rules based environment
• Linear detection of logs for incident reporting
Big Data Analytics• Seeks anomalies to correlate
• Examines entire environment for log relationships
• Tracks unusual activity working backwards to context
Actively investigate anomalies and provide context around incident detection.
Proactively identify the unknown through machine based learning to identify data pattern changes. Alert Trending creates a visual context for the behavioural anomalies.
Anomaly Detection
Do you have your house in order?
• CSIRT Ready – Is Incident Response defined, documented, practiced?
• Asset Classification and Owners – Defined and updated?
• Ticket Pile-Up – How reactive are IT and Product teams to findings?
• War Games – When was the last table-top IR exercise?
• Response Procedures – What will we actually do when attacked?
What happens during onboarding?
Onboarding is conducted using systematic processes with detailed operational readiness checklists
Operational Item Description
Develop detailed project plan Define a comprehensive project plan including stakeholders, timelines, and key assumptions/risks
Asset list Document the asset list of record including serial and version numbers
Architecture documentation Define reference implementation architecture including security zones, network information, and management interfaces
Account creation for the operational team Catalog the authorized users and account permission levels including the approved process to provision and manage system accounts
Run and Build Books Establish operational run books for managed technologies
OS and application are up-to-date Validate the operating systems are updated and have the appropriate licensing defined
Endpoint Catalog Documentation of valid end-points and procedures for adding and removing endpoints into protection scheme
Establish Health Monitoring Assure visibility into the system health of the managed devices to provide up/down reporting
Provide appropriate ticket system access Assure access to the system and appropriate permissions exist to manage tickets as defined in SLAs
Complete Escalation Process Document Document the end-to-end escalation tree for primary, secondary, and backup contacts for all levels of agreed upon service descriptions
Production Readiness Plan the cutover deployment timing and relevant stakeholders to approve transition rollback criteria
Six Onboarding Best Practices
1. Define “notable event" vs "incident" based on triple ds (disruption, degradation, nuisance)
2. Build work products such as asset lists, critical applications, SEV priority
3. Vulnerability scoring definition
4. Defined ownership of process and escalation
5. Poor man’s owner lists: use top users, emp directory, last logon
6. Agreed upon operational readiness checklist
Sample Operational Readiness Checklist
• How many users on the network?• What is the make model of each appliance and the management server?• Are any of the appliances near eol?• Any unresolved support issues with the manufacturer?• What policies are in place today? Fim? Ips? Firewall?• What new policies are required?• Are the devices strictly firewall only, or multi-purpose/next-gen?• Are there other features enabled? AV, IPS, email GW, web proxy/GW?• How many physical appliances are in-scope for managed services?• What is the location of each appliance? Head office? Main data center? • Any new physical or virtual interfaces on existing platforms to be operationalized?
Fundamentals of SecOps
• Detection
• Evidence Collection
• Containment
• Forensic Analysis
• Remediation
• Communication
Mr. Fundamental
It’s all about the use cases
1. Identify and Analyze MVAs and HBIs devices (Most Valuable Assets) (High Business Impact)
2. Model use-cases around your MVA and HBI devices
3. Use cases will tell you what logs you need (not the opposite)
4. Then pick the tech to implement use cases
Six Best Practices for Use Case Dev
1. First Things First - Ensure critical conditions produce notification
2. Environment Centric - Build alert rules specific to environment and requirements
3. Fluid Thresholds - Ensure appropriate thresholds are applied to reduce false alarms
4. WhatandWhy- Know what event sources are logging to the SIEM and why
5. What’smostimportant- Categorize alerts according to severity levels
6. TrackThemAll- Ensure non-critical events are excluded from notification but reviewed
Sample Use Case References
• Popular SIEM Starter Use Cases
• AlienVault SIEM Use-Cases
• SANS Critical Security Controls ***
• NIST 800-53 ***
***Not purely use cases, but great source to help brainstorm
Sample Use Case Checklist
• What situations keep you up at night? • What alerts and reports do you expect to get from the SIEM? • Will the platform be managed internally or outsourced? • Is there a list of all devices/assets to be monitored by the SIEM? Which are most critical?• Which devices are natively supported by the SIEM and which ones require a custom parser?• Is the SIEM required to meet some form of compliance (e.g. HIPAA, PCI, SOX)?• How are the monitored devices geographically dispersed? • How do asset owners (of the monitored devices) feel about an agent versus agentless solution?• What devices need to send logs to the SIEM in order to get those alerts and reports? • Is there a requirement to incorporate network data elements into the SIEM? • If managed internally, what training options does the vendor provide and who exactly will be
managing/monitoring/maintaining the solution?
Do’s and Don’ts
• Don’t do a POC of MSSP
• Do unannounced VA scans and pen tests
• Don’t have 5 minute SLAs
• Do provision enforceable SLA penalties
• Don’t just default on a one-year contract
• Do define success with simple KPIs

Information Security Is What We Do
DIY vs Outsource?
• Is your focus Strategic or Tactical?
• How important is scale?
• How important is control?
• Where’s the Data?
• Quality will cost millions
• Incur lengthy IT implementations
Can 8×5 monitoring be just as good as 24×7?
• YES – Of Course!
• Don’t need 24x7 until good at 8x5
• Focus on fundamentals of incident detection and response
• Prioritize key indicators and alerts to “page out” if fired
• Mature to a SOC for 24x7 to transform IR (NOT other way around)
• NO - Not a Chance!
• Bad guys don’t follow store hours à staff burn out • Downward Spiral: Focus on tactical vs strategic
• Not enough security talent to retain
