Countermeasures Against Tampering of Data Recorded in the File
There are environment definition files and other such files in the operating environment of an OLTP
application. If the information in this file is illicitly tampered with, it may disable an OLTP application and
cause various problems. An effective countermeasure against this threat is to set appropriate access
permissions on this file. For Solaris OE system or Linux system, refer to Enhancing Security (Protecting
Interstage Resources) in Appendix A.
Periodic backup is also effective. For the information about backup, refer to Maintenance (Resource
Backup) in the Interstage Operator's Guide.
Countermeasures Against Exploitation of Information Recorded in Files

these files are also a part of resources, and it is important to prevent exploitation of them. To minimize
the risk of exploitation of information, it is effective to set appropriate access permissions on these files.
For Solaris OE system or Linux system, refer to Enhancing Security (Protecting Interstage Resources)
in Appendix A.
