MVC locks session variables to ensure thread safety and concurrency control, but takes a conservative approach to. Unfortunately the ASP.NET pipeline will not process requests belonging to the same session concurrently but queues them, and executes them serially. MD5 Hash of the configuration item record.Д¬onfiguration item record stored in XML format. The design of ASP.NET includes the valuable session variables that enable the application to keep track of individual sessions. The RECORD_SCHEMA column stores an XML schema that can be used to validate the structure of the item or relationship XML documents.Д¬onfiguration item type - foreign key to CMDB_TYPES Each type has a system generated id and a unique name + version. An XML Type column in CMDB_RELATIONSHIPS can be used to store XML documents that include data to describe the relationship.Д¬MDB_TYPES stores metadata that describes configuration items and relationships. It uses the source and target configuration item ids in conjunction with the relationship type to identify the relationship. This can be used to help identify configuration items that exist in more than one configuration.Д¬MDB_RELATIONSHIPS stores the relationships between configuration item records. An MD5 hash value is created for the XRECORD. The configuration record is stored as an XML document in the XRECORD column. The name, version and type combination form an unique constraint for the table. Each record has a system generated id along with a name, version and type id. CMDB_ITEMS and CMDB_RELATIONSHIPS are arranged in a bill of materials structure.Д¬MDB_ITEMS stores configuration item records. It has 3 tables: CMDB_ITEMS, CMDB_RELATIONSHIPS and CMDB_TYPES. The diagram below shows an example of this. One way around this is to incorporate XML Type columns into the design. It is difficult to design a database schema that is able to record metadata for a diverse range of configuration items. This can be a problem when you decide to store configuration item records in a database. The structure of configuration item records will also differ. For example, the properties of a network switch are different to the ones for a database. The storage requirements for these systems may differ. Assign users to the appropriate profile.The configuration management database needs to be able to store records for every configuration item and relationship in the systems it supports. Create profiles that conform to the DoD requirements. Limit concurrent connections for each system account to a number less than or equal to the organization-defined number of sessions using the following SQL. If the DBMS settings for concurrent sessions for each profile are greater than the organizationally defined maximum number of sessions, this is a finding. SELECT * FROM SYS.DBA_PROFILES WHERE RESOURCE_NAME = 'SESSIONS_PER_USER' Retrieve the settings for concurrent sessions for each profile with the query: Oracle Database 11.2g Security Technical Implementation Guide For example, 2 might be an acceptable limit for general users accessing the database via an application but 10 might be too few for a database administrator using a database management GUI tool, where each query tab and navigation pane may count as a separate session. In deciding on the appropriate number, it is important to take into account the work requirements of the various types of user. The organization will need to define the maximum number of concurrent sessions by account type, by account, or a combination thereof. Unlimited concurrent connections to the DBMS could allow a successful Denial of Service (DoS) attack by exhausting connection resources. This requirement addresses concurrent session control for a single information system account and does not address concurrent sessions by a single user via multiple system accounts. Limiting the number of allowed users, and sessions per user, is helpful in limiting risks related to Denial of Service attacks. Properly implemented RBAC controls should include lock down based on day, date, time and location. Application management includes the ability to control the number of users and user sessions utilizing an application. Session management is a comprehensive IT Security process to control, monitor and record administrative access to servers, databases and network devices.
