17 Vulnerability Trends Zero-day Key Definition: A zero-day vulnerability is one for which there is sufficient public evidence to indicate that the vulnerability has been exploited in the wild prior to being publicly known. From July 1st - December 31st 2006, Symantec documented 12 zero-day vulnerabilities, a significant increase over the previous two reporting periods H dropped to 6 documented zero-day vulnerability attacks - but these are still risks Attacks with no protection No patches No Anti-virus signatures No pre-built Firewall rules No attack (Network IPS) signatures SCSP Product Overview 17

28 VMWare ESX 3.5 Host Protection Challenges VMWare ESX Host is a RHEL kernel and increasingly subjected to vulnerabilities and attacks. A malware can potentially use the host as launching pad for attacks to the guest OS. Host Guest Guest Guest SCSP Benefits Provides Host IDS to monitor user, system and resource activities and report on realtime intrusions Protects ESX host with its IPS policies to provide firewall protection, device control, configuration and system lock down, admin access control and file system protection Provides protection so you can comfortably put PCI Server in virtualization Symantec Critical System Protection 28

53 Windows Out-of-the-Box Prevention Policies A starting point for customers. Each policy is built on the same core components (BCDs, PBR, macros, etc). The only difference is which options are defined by default. Easily move from policy one to another by just adjusting options. Core Strict Core OS protection with maximum application compatibility Instant hardening of commonly attacked processes/applications + Buffer Overflow (BO) protection All unspecified programs* are treated as safe, except for BO protection and inbound network controls Recommended policy for server deployments Strict OS and application control BO & Network lockdown no inbound access, outbound limited to ports 80, 135, 389 & 443 Unspecified programs* are confined (cannot write critical system files nor system executables) Limited Execution Limits execution of non-server applications Same functions as Strict, except all interactive processes are denied except those in whitelist * Unspecified programs are handled by Default process sets 53

54 HIPS Configuration Comparison System Process Traditional IPS/Firewall Monolithic Policy Priority Denies System Process SCSP Modular Policy Global Policies/rules are in a sequential list, with each system call being checked against the whole policy list. Allows Denies Processes are assigned to a Process Set; then only the corresponding Process Set rules are scanned Process Set X General Services Application X Actual response is dependent on rule order. To add to a policy, the user must understand exactly how resulting rule sequence will execute To control a new application, the user need only be concerned with the new process (rule) set SCSP Product Overview 54

55 HIPS Operational Comparison Traditional IPS/Firewall Monolithic Policy System Process Priority Denies Priority Denies System Process SCSP Modular Policy Global Every process call check starts at the top and work sequentially down the entire list Allows Denies Allows As a process starts, it is assigned to a Process Set. From that point on, process calls are checked against a limited set of policies Process Set X #3 #2 #1 General Services Application X As the policy is customized, the list grows leading to slower and slower performance. Denies As the policy is customized, performance impact is small - only affected with changes to call related rules in Global, General or the app specific process sets New app, but unrelated Network IPS policies work the same way, adding extra impact reassembling & scanning every packet into/out of the system SCSP Product Overview 55

56 PCI Firewall Requirement (Req. 1) Primarily focused on network firewall features SCSP augments network firewalls with host based protection, so not all features are required on the host SCSP protects against additional attacks from within the network security perimeter and ensures inappropriate application communications are controlled SCSP Product Overview 56

57 PCI Monitoring Requirements (Req. 10) SCSP provides both host lockdown (IPS) and monitoring to audit all of these items SCSP s host based prevention capabilities can monitor and control access to audit tools and data. This includes locking audit data to access/use by only authorized users and applications Real-time IPS lockdown limits access and changes to system audit logs not possible with log collection tools IPS events provide immediate notification about abnormal system behavior and access. Events can trigger , SNMP and/or log based alerting SCSP Product Overview 57

58 PCI Data Restriction Requirements (Req. 7) SCSP can limit user access to files and registry keys based on application and user/group SCSP IPS policies can block access to files/registry keys by any user include root or administrator accounts, but allow specific applications to still access and/or modify files SCSP s default IPS policies block changes to applications and system files. Customers can specify acceptable patch/system management tools (and users), as well as lock down their implementations of sensitive applications/content SCSP Product Overview 58

59 PCI Data Restriction Requirements (Req. 11) SCSP s IPS feature includes a firewall to control application traffic SCSP s behavioral IPS can detect and block threats that network technologies can miss including insider abuse or abuse of insider accounts Host based protection is needed to detect all changes Note: once a week may meet PCI, but is not enough to prevent hacking SCSP s IDS and IPS policies protect and monitor key system and application files SCSP meets and exceeds the minimum PCI recommendations by providing exploit prevention and configurable auditing to monitor access and usage on the system in real-time SCSP can identify which users and applications were used to modify files using either IPS or IDS file auditing policies SCSP Product Overview 59
