Chapter 1: Security Risks
1-10
Countermeasures Against Damage to Data
There are some J2EE applications that use databases. For this type of application, the data stored in
those databases should also be protected. In addition to the security function that the database itself
has, periodic data backup is an effective countermeasure against damage to data.
Countermeasures Against Damage to Files
There are required files in the operating environment of a J2EE application. If these files are damaged
for some reason, the J2EE application cannot operate. An effective countermeasure against this threat
is to set appropriate access permissions on these files.
