EnhancementsSentinel 7.0.3 includes the following enhancements: Out-of the-Box Support for Synchronizing Data to PostgreSQL DatabasesSentinel versions prior to 7.0.3 allowed creating data synchronization policies that would synchronize event data to only external MS SQL 2008 and Oracle 11 databases. Syncing event data to the internal PostgreSQL database could be done only using Report Data Definitions (RDD). Sentinel 7.0.3 now allows you to create data synchronization policies that can synchronize event data to both internal and external PostgreSQL databases. (BUG 758956) Ability to Configure the Number of Processors for mksqaushfsSentinel 7.0.3 includes a new property, mksquashfs.numprocessors, that allows you to specify the number of processors for mksquashfs to use when compressing the index on the event data. This capability enables you to make more use of additional CPUs that may be available on some systems. You can set this configuration in the configuration.properties file. (BUG 774458) Implementation of Intruder Detection and Lockout MechanismsSentinel now supports intruder detection and lockout to prevent potential brute-force attacks. Sentinel provides several configurable parameters that help you implement intruder detection and lockout mechanisms. failedAuthDelay: Specifies the duration that a subsequent authentication request must wait after a failed authentication for a specific user. The default value is 2000 (2 seconds). If the value is 0, the delay is disabled. Note: You must set this value for each user. If an authentication request for User A fails, it does not cause a delay for an authentication request for User B. intruderDetectInterval: Specifies the time period in which consecutive failed authentication requests for a user must occur for Sentinel to identify the failures as a possible intruder detection. For example, if the value is 300000 (5 minutes) and four failed authentication requests happen within 4 minutes, but the 5th consecutive request happens 5:01 (minutes:seconds) later than the 1st failed request, Sentinel does not consider the requests suspicious. If the value is 360000 (6 minutes) and the same sequence of failed requests happen, Sentinel considers the requests to be suspicious. The default value for this parameter is 300000 (5 minutes). intruderDetectMaxFailedAttempts: Specifies the number of consecutive, failed authentication requests that must occur for Sentinel to consider a user name during the intruderDetectInterval for the requests as suspicious. If the value is 0 then intruder detection and lockout is disabled. The default value for this parameter is 5. intruderDetectLockPeriod: Specifies the duration that a Sentinel user account remains locked when the user account is automatically locked in response to a suspicious series of failed authentication requests. If the value is 0, automatically locked accounts are not automatically unlocked. They must be unlocked manually by an administrator. The default value for this parameter is 900000 (15 minutes). intruderDetectAdminAutoLock: Specifies whether or not the Sentinel admin account is subject to automatic locking in response to a series of failed authentication requests. The default is false since a denial-of-service attack exists in which an attacker can continually lock the built-in admin account, unless there is a separate administrator account. The values listed above are defined in the AuthenticationService component of the /etc/opt/novell/sentinel/config/server.xml file. After you make any manual modifications to the values, you must place this component in the component properties override file: /etc/opt/novell/sentinel/config/obj-component.AuthenticationService.properties. This ensures that the modified settings are not lost during an upgrade. (BUG 780789) Software FixesSentinel 7.0.3 provides software fixes for the following issues.
