Deep Security: Securing the New Server Cloud Virtualized Physical Servers in the open Servers virtual and in motion Servers under attack 2 11/9/09 2

Dynamic virtual machines Dynamic: Reverted Paused Restarted Cloned Moved Security challenges Achieve and maintain consistent security Propagation of vulnerabilities and configuration errors Maintaining an auditable record of the security state 3 Third Briga

Virtual Machines Need Specialized Protection 1. Same threats in virtualized servers as physical: OS & Application vulnerabilities and Configuration errors allow Malware to attack & infect 2. Plus Dynamics of virtualization causes some new challenges: Dormant VMs Resource contention VM Sprawl Inter-VM traffic vmotion 4

Virtualization Challenge: Securing dormant VMs Dormant VM Dormant VM Active VM Active VM Active VM AV App AV App AV App AV App AV App ESX Server Dormant VMs are unprotected These include VM templates and VM backups Dormant VMs cannot run scan agents yet still can get infected Dormant VMs have problem of stale AV signatures 7/7/2009 5

Virtualization Challenge: Full System Scans Scan 3:00AM Scan 3:00AM Scan 3:00AM Scan 3:00AM Scan 3:00AM Scan 3:00AM AV App AV App AV App AV App AV App AV App Typical AV Console ESX Server Resource Contention with Full System Scans Existing AV solutions are not VM aware Simultaneous full AV scans on same host causes severe performance degradation No isolation between malware and anti-malware 7/7/2009 6

Virtualization Challenge: VM sprawl Dormant VM Dormant VM Active VM Active VM Active VM Newly deployed VMs Sec App Sec App Sec App Sec App Sec App Sec App AV App AV App Sec App ESX Server Infrastructure Managing VM Sprawl New VMs are just a click away, security weaknesses replicate quickly Security provisioning creates bottlenecks in VM deployment or VMs emerge without adequate security Lack of visibility into or integration with virtualization console increases management complexity 7/7/2009 7

Virtualization Challenge: Inter-VM traffic AV App AV App AV App AV App Inter-VM traffic Network IDS/IPS vswitch ESX Server vswitch ESX Server Inter-VM traffic Network IDS/IPS solutions cannot see VM to VM traffic within an ESX server First-generation security VMs require intrusive vswitch changes 7/7/2009 8

Virtualization Challenge: VM Mobility AV App AV App vmotion AV App AV App Network IDS/IPS vswitch ESX Server vswitch ESX Server Mobility of VMs (vmotion & vcloud) Existing solutions need reconfiguration and are cumbersome to manage Can result in VMs of different sensitivities landing on same server Deployment of VMs in cloud (IaaS) environments are unprotected 7/7/2009 9

Retreat To The Server (VM)! De-Militarized Zone (DMZ) IDS/IPS Firewall IDS/IPS Gateway (Malware) Firewall & IDS/IPS File Integrity Monitoring & Log Inspection Anti-Malware Mission Critical Servers Business Servers / Endpoints 5/28/2009 13 13

Deep Security Modules Firewall Centralized management of server firewall policy Pre-defined templates for common enterprise server types Fine-grained filtering: IP & MAC addresses, Ports Coverage of all IP-based protocols: TCP, UDP, ICMP, IGMP Deep Packet Inspection Enables IDS / IPS, Web App Protection, Application Control Examines incoming & outgoing traffic for: Protocol deviations Content that signals an attack Policy violations. Integrity Monitoring Monitors critical files, systems and registry for changes Critical OS and application files (files, directories, registry keys and values) Flexible, practical monitoring through includes/excludes Auditable reports Log Inspection Collects & analyzes operating system and application logs for security events. Rules optimize the identification of important security events buried in multiple log entries. 11/9/09 14

Now, Practically Speaking Firewall Enables: Comprehensive control over inbound and outbound traffic Incident containment Location awareness of resources in virtualized environments Deep Packet Inspection Enables: Vulnerability specific protection (i.e. Microsoft Tuesday) Application-layer control Prevents: Zero-day attacks on known and unknown vulnerability Web application attacks including SQL Injection and Cross Site Scripting (XSS) Attacks hidden in encrypted data Integrity Monitoring Enables: Near real-time detection* of potentially malicious changes Extensive file property checking, including attributes (PCI 10.5.5) Alerting on errors signaling attack Golden host to compare changes against a predefined baseline and manage acceptable change * Log Inspection Enables: Optimized collection of security events across the datacenter, multiple server types Based on the OSSEC rule syntax, widely deployed HIDS Saves bandwidth in log collection from servers 11/9/09 15

Firewall Decreases the attack surface of physical and virtual servers Centralized management of server firewall policy Pre-defined templates for common enterprise server types Virtual machine isolation Fine-grained filtering IP & MAC addresses, Ports Coverage of all IP-based protocols TCP, UDP, ICMP, Coverage of all frame types (IP, ARP, ) Prevents Denial of Service (DoS) attacks Design policies per network interface Detection of reconnaissance scans 11/9/09 18

Deep Packet Inspection IDS/IPS Vulnerability rules: shield known vulnerabilities from unknown attacks Exploit rules: stop known attacks Smart rules: Zero-day protection from unknown exploits against an unknown vulnerability Microsoft Tuesday protection is delivered in synch with public vulnerability announcements. On the host/server (HIPS) Web Application Protection Enables compliance with PCI DSS 6.6 Shield vulnerabilities in custom web applications, until code fixes can be completed Shield legacy applications that cannot be fixed Prevent SQL injection, cross-site scripting (XSS) Application Control Detect suspicious inbound/outbound traffic such as allowed protocols over non-standard ports Restrict which applications are allowed network access Detect and block malicious software from network access 11/9/ 09 19

Integrity Monitoring Monitors files, systems and registry for changes Critical OS and application files (files, directories, registry keys and values, etc.) On-demand or scheduled detection Extensive file property checking, including attributes (PCI 10.5.5) Monitor specific directories Flexible, practical monitoring through includes/excludes Auditable reports Useful for: Meeting PCI compliance Alerting on errors that could signal an attack Alerting on critical system changes 11/9/09 20

Log Inspection Getting visibility into important security events buried in log files Collects & analyzes operating system and application logs for security events. Rules optimize the identification of important security events buried in multiple log entries. Events are forwarded to a SIEM or centralized logging server for correlation, reporting and archiving. Useful for: Suspicious behavior detection Collection of security-related administrative actions Optimized collection of security events across your datacenter Advanced rule creation using OSSEC rule syntax 11/9/09 21
