Bulding Soc In Changing Threat Landscapefinal Bulding Soc In Changing Threat Landscapefinal Presentation Transcript

  • building  a  Security  Opera2ons  Center  and   KPI  for  a  SOC  Mahmoud YassinLead Security Architect Mahmoud.yassin@outlook.com
  • 2 Overview Companies like yours ? Insights into building a SOC team in a changing threat landscape? Measuring the effectiveness of SOC using key performance indicators Using 24*7 monitoring to minimize overall risk across an organization Conclusions
  • 3 Companies like yours ?
  • 4 Threat changed landscape §  Who is targeting you? §  What are they after? §  Have they succeeded? §  How long have they been succeeding? §  What have I lost so far? §  What can I do to counter their methods? §  Are there legal actions I can take?
  • Today’s Threat Landscape Undetected Attacks External Attacks Vulnerabilities and compromised Trojans, viruses, worms, phishing .. machines may lay dormant for Not protected by firewalls. Requires months, awaiting an attacker to IPS exploit them. Requires vulnerability Intrusion Vulnerability awareness and end-point intelligence. Prevention Assessment Network Intelligence User Intelligence Physical / Data Center Security Network Network Behavior Access Porous Perimeter Analysis (NBA) Information Leakage Control (NAC) Every machine a peering point Point-point VPNs + desktop and Laptops carry infection past mobile internet connections firewalls. Requires IDS provide ample opportunity. Requires compliance monitoring and enforcement

  • The 3 (main) functions of a SOC §  The reason for a SOC: Business Continuity, Risk Mitigation, Cost Efficiency §  What does the SOC do? 1.  Real-time monitoring / management §  Aggregate logs §  Aggregate more than logs §  Coordinate response and remediation §  “Google Earth” view from a security perspective 2.  Reporting / Custom views §  Security Professionals §  Executives §  Auditors §  Consistent 3.  After-Action Analysis §  Forensics §  Investigation §  Automate Remediation §  Virtues of a SOC: cost efficiency, measurable improvements in availability, lower risk, relevance to the business, transparency, passing audits, consistency, reproduce-ability §  Vices of a SOC: expensive, little meaning to the business, opacity to the business, no impact on risk, failing audits, inconsistency
  • Prioritization and Remediation §  Deal with what’s most relevant to the business first! −  Gather asset data −  Gather business priorities −  Understand the business context of an incident §  Break-down the IT silos −  Automate the Action after incident discovery −  Coordinate responses −  Inform all who need to know of an incident −  Work with existing ticketing / workflow systems §  Threat * Weakness * Business Value = Risk §  Deal with BUSINESS RISK

  • SOC KEY DIFFERENTIATION AREAS
  • Integrated CMDB CMDB Data§  Configuration Management Database (CMDB) features: §  Connectors sync data with external systems Config Work §  Create, update, and view CIs Items Items §  Create relationships among CIs, WIs, IT staff, and Active Directory® Domain Services (AD DS) users §  Automatically track CI change history Relationships §  Service definition and mapping Integrated | Efficient | Business
  • Incident ManagementKeep users and data center services up and running, and restore service quickly §  Process workflows −  Escalations −  Notifications −  Remediation §  Customizable templates §  Knowledge & History §  Automatic incident creation −  Desired Configuration Monitor (DCM) errors −  Operations Manager alerts −  Inbound Email −  Portal
  • Case ManagementEnables organizations to identify and track problems •  Problem creation from similar incidents or Attacks •  Link Incidents and Change requests to problem •  Auto resolution of Incidents linked to the Problem
  • Change ManagementMinimize errors and reduce risk §  Typical Change Models −  Standard, Major, Emergency… −  Review and Manual activities §  Customizable Templates §  Workflows and Notifications §  Analyst Portal −  Approvals via Web §  Relate Change Requests to Incidents, Problems and Configuration Items
  • Vulnerability Management Process 1. DISCOVERY (Mapping) 2. ASSET 6. VERIFICATION PRIORITISATION (Rescanning) (and allocation) 5. REMEDIATION 3. ASSESSMENT (Treating Risks) (Scanning) 4. REPORTING (Technical and Executive)
  • Investigations and Forensics §  Being able to investigate and manipulate data §  Visualization §  Post-event correlation §  Managing by case / incident §  Chain of custody §  Integrity of data §  Remediation Automation
  • SOC Objectives A Framework for Security OperationsSecurity Environment SIEM Perimeter Network Internal Systems & Applications eCommerce Capabilities Operations Operations Security Objective ü Log Management " Privileged user monitoring ü Asset Identification Access Control Enforcement " Corporate policy conformance ü Baseline " Troubleshoot network & security Real-time Monitoring events ü Report & Audit " “What is happening?” " Confirm IDS alerts ü Alert False Positive Reduction " Enable critical alert escalation ü Forensic Analysis " Watch remote network areas Correlated Threat Detection " Consolidate distributed IDS alerts ü Incident Management " External threat exposure ü Automate learned Inciden Watchlist Enforcement " Internal investigations Automate Remediation Unauthorized Network Service " Shutdown rogue services Detection " Intellectual property leakage " Proof of delivery SLA Compliance Monitoring " Monitor against baselines = Most critical = Highly desired = Desired
  • 33 SOC Recommendation for APT(cont.,)§  SOC Process automation§  have VIM service feeding your SOC and follow-up with different parties .§  Scan for zero days§  Insure security of your security products (patches zero days focus on perimeter devices ).§  Forensic is not an luxury service SOC should have the tools and ability to analyze. (payloads – sandbox…..)
  • 34 SOC Recommendation for APT (cont,…) §  Correlate across layers (perimeter with end point output of IDS & IPS) §  Monitor privileges on suspected or alerted workstation. §  Enforce Privilege change if there is an infection. §  Manage Exceptions §  Contact Authorities (Cert , ISP’s , Law Enforcement)
