Tool of auditing DataBase access「WEEDS DB-Trace」
「I want to grasp DataBase acccess which places personal information.」
「Auditing internal control indicates access log, I don’t know what should I do.」
「In charge of system fears that deterioration of performance, and auditing DataBase can’t start.」
「I can’t audit, because that I don’t know how to see, while getting logs.」
Customers who try to audit DataBase access seems to worry such things.
WEEDS DB-Trace which is offered to wide-range customers when law protecting personal information became in effect in 2005, April can apply various customer situations and be installed without worrying.
What is auditing Database access
What is Database access indicates “SQL”, there are 2 main types of this. One is a sentence of DDL (making and changing table, registering and changing stored procedure), the other is a sentence of DML（referencing,adding,updating,deleteing etc. data）.
And, there are 2 main types of DataBase access.
As the diagram below indicates, ① access from application, ② access directly which is by operations and maintenances.
To grasp types of these accesses, and prove justice access to DataBase is auditing access DataBase.
What is WEEDS DB-Trace
WEEDS DB-Trace is that disposal of getting and anlysis information like when, which user, from where, to which inforamiton, what access on a basis of log which is generated by RDBMS (Oracle,SQL,Server,DB2,Teradata) for getting all accessses.
Logs which is a disposal of anlysis by WEEDS DB-Trace are transfered to log repository server, is loaded with log DataBase. Logs are managed by WEEDs Log-repository Manager, generate auditing report, maintenance of logs (regular avoiding,backup, restore).
Logs of RDB which are outputted for DataBase objected auditing are eliminated by WEEDS DB Trace which after disposal of analysis and we cope without no-burden of Database objected auditing.
Point of auditing Database access
Critical points of auditing this Database access as indicated below.
・To get accesses from all users and all route.
・To keep indispensable information for auditing access
when ,which user from where which information what access
・To audit easily access log (trace that prove auditing)which getting and keeping.
It is indispensable to build situaion above for auditing access.
WEEDS DB-Trace is a tool which has all of these points.
Point：To get all accesses
You can know that WEEDS DB Trace can get all access logs from architecture above
①Because that generate logs which guarantee as inputting、WEEDS DB-Trace which is a structure which disposal of analysis from log files no-leaked also doesn't leak getting.
For example, there is a method of getting from RDBMS memory, but it is possible to cause getting leak, if it disappears from memory. It is difficult to prove no leak getting such feature, because of this, it should be avoided as a means.
Because it adopts things outputted as a file of OS, if by any chance, WEEDS DB Trace doesn't work, logs outputted by RDBMS doesn't disappear.To disposal again, it can get access log.
And, it gets logs if access is from any route by using logs of RDBMS. For example, there is a mean getting access log from network packet, if it access by console of DB server, it gets access log without passing network.
Point：Keep indispensable information for auditing access
It is possible that WEEDS DB-Trace gets following information as a item of access log. Especial critical item is "table and field accessed","application for using access" .

Point：To audit easily access log
Simply "auditing SQL" is no-efficient by eyes and eliminate risk of leakauditing.
The knowledge of SQL is necessary for judging whether injustice or not even though these following simple sentences of SQL
How should we do audit?
It is unreal to audit sentences of SQL case by case by eyes in auditing DataBase access as above indicated.
Monthly auditing, we would like to total up access and audit it, but, we can't total up access when it has SQL as texts.
WEEDS DB-Trace analyze sentences of SQL uniquely、keep logs separately which table, which field which condition which access(referewnce, adding, updating, deleting,etc.)
It will be abvious what access is one by one from which table,which field.
To hold logs extract logs which is goal for auditing from massive logs.
For example, a goal of auditing is "countermesure of personal information protection", it extracts only "reference of personal information". If "injustice manipulation of financial statement", it extracts only changing table which is related to financial statement (insert,updating,deleting).
And, it is possible to adding up accesses by table, to report data access collected by table monthly as following audit report.
It is difficult to audit without these restoring logs.
WEEDS DB-Trace has thefollowing audit report normally.

| The view of SQL | The view of access to DataBase.（By SQL）In case of log-in and DB of an intended audit, it outputs reports. | ||
To audit systematically audit is registered.
It is possible to audit systematically eliminating dependent if holding significative access-log.
The policy of audit previously registered, checking enormous access log and to extract log against policy work out it.
| The policy of audit | |
|---|---|
| Setting overtime | 「The report of access overtime」 outputs operation at no-named hour automatically. |
| Setting authorized user | 「The report of operation by authorized user」extracts automatically history of operation by authorized user. |
| The table audited・ Setting field |
The report of access of table audited extracts atomatically applicable access for table, field registered as an intended audit. |
| Setting massive Data | The report accessing massive Data extracts automatically access over named number of read-bite and of write-bite. |
| Settting loading access of DB | The report high loading access of Data extracts automatically access over level of named hour |
One click creates "the report daily auditing","the report monthly auditing" by setting up policy of audit above.
To classify“Logs of an intended audit”and“Logs of no-intended audit”
to get DB of access-log, it collect massive access-log which can be classified no-intended audit. Access of disposal of night-time automatically batch is applicable.
Because that batch is worked at night is not by manipulation, so that it is classified no-intended audit. However, if holding such access-log, it is not easy to original audit because of massive log-data.
WEEDS DB-Trace classify no-intended audit which is batch night-time, and doesn't restore it as log-data.
The tool classify them as batch night-time while extracting conditions by above items of logs getting. Generally speaking, classifying logs judgingbatch night-time automatically by the name of application.

Is it enough to hold log of Oracle and SQL Server?
People sometimes question that WEEDS DB-Trace uses RDBMS normal log, To hold RDBMS normal log would be log auditing.
However, RDBMS normal log cause high-risk minus-point as a log auditing.
You can refer the following server of Oracle and SQL
| Oracle ： The issue about Audit-log | |
|---|---|
| Log | Oracle Audit log（There are two types of outputting table and event log.） |
| Degree of accuracy of log | ・It can't get access-log of user （In case of outputting table） ・Sentences of SQL hold only until 2,000byte ・Can't know what access from which application ・For example, in case of refer table 3 table by 1 SQL, it generates 3records of same logs. ・Can't get sentences of SQL by method of outputting to event log. （Only“SELECT”etc.） |
| Safety | To hold log without encryption. It has risk that leak personal informtion and confidential information from sentences of SQL （Especially Data itsself in case of sentences of Insert） So that, log itsself cause risk of leak information. |
| Operation auditing | ・Can't audit integrated because of different items of getting by version. ・Can't avoid auditing deterioration of performance （To compete log inserted and log deleted, dumbing down seriously.） ・To give us a trouble for audit operation,because that it is difficult to search by event log and display a list |
| SQL Server ： The issue about Trace-file | |
|---|---|
| Log | Trace file |
| Th packet of log | The all contents is 2 byte even if half-size character, because that file of log is “Unicode”. （It can be compression of 1/2 logs only by altering SJIS） |
| Safety | As Oracle、 To hold log without encryption. It has risk that divulging personal-information and secrecy information from sentences of SQL. （Especially sentence of Insert is Data in itsown ） Log itsself causes risk of divulging-information |
| Operation audit | ・It is difficult to processing and adding and extracting because of audit only SQL profiler. ・When information of log （It is impossible to audit entirely sentences ofSQL.） |
Is it possible to get access-log by reference packet of network and memory.
WEEDS DB-Trace doesn't apply architecture which getting DB of access-log(SQL).
Because that it cause generating leak acccesslog by high-possibility (It is impossible to prove no-leak getting.)
