1-8 Introduction The Type Enforced environment Files available to a process Process-to-file access is controlled by a Domain Definition Table that maps out the various classes of data files and processes that may be running on the Sidewinder G2. The table specifies which process domains can access different types of files and what type of access is allowed (such as read/write/execute). This table cannot be circumvented. Your system is pre-configured so that domains have access only to the files they need. The Domain Definition Table cannot be changed while the Operational kernel is running. This prevents intruders from tricking the kernel into modifying the table. Also, Type Enforcement prevents intruders from installing software that may be used to circumvent Sidewinder G2 security mechanisms. Type Enforcement’s effects The previous section outlined how Type Enforcement works. Listed below are the major ways in which Type Enforcement affects you and other users: Non-administrative users will not be aware of Type Enforcement (unless they try to perform unauthorized activities). In the Operational kernel, there is no concept of a super-user who can have complete system control. The “root” account has no special privileges. The Admin role operating in the Admn domain has access to most system files, but is still not as powerful as root on a standard UNIX system. Domains make it difficult for an intruder to do damage. Breaking into the domain in which an application is executing does not provide access to the files required for administering that application. Some system administration cannot be performed in the Operational kernel and must be done in the Administrative kernel. While in the Administrative kernel, the Sidewinder G2 is not accessible to any other user or the Internet. When the Administrative kernel is running, Type Enforcement is turned off, which allows you to perform procedures such as a software upgrade or a full system backup and restore.
Additional Sidewinder G2 operating characteristics Figure 1-4. Multiple Type Enforced areas (burbs) on Sidewinder G2 Additional Sidewinder G2 operating characteristics This section lists additional significant differences between Sidewinder G2 and a standard UNIX system. Burbs and network stack separation While installing or managing the Sidewinder G2, you will notice the use of the term "burb." Burb is a term that refers to a set of one or more interfaces that are to be treated the same from a system security policy point of view. Each burb has a unique name (for example, internal, external) that you assign during initial configuration. As an example of how burbs are used, suppose your organization has two internal (protected) networks that need to be connected to the external network (Internet), but the corporate security policy requires that there be limited or no information flow between the two internal networks. In this scenario, you would configure three burbs for your Sidewinder G2, as shown in Figure 1-4. The security policy must be defined to enforce the required control over information flow between the two internal security burbs and between the external burb and the individual internal burbs, while also protecting the internal burbs from unauthorized access from the Internet. trusted networks Sidewinder G2 showing Type Enforced network areas (burbs) R router Internet Introduction 1-9
