user sys and locking system
Hi allWe have 10.2.0.4 on solaris 10.
Currently we have I.T. audit on our environment, and the auditor commented to lock the user sys and system and use a single user with any name (not the name generic oracle) and grant him the privilege of sys and system and use this user for admin purposes. is this true?... is it recommended?
Please notify
Hello
I think that this is not a good way to lock SYS.
In addition, if you connect as administrator (root for Unix/linux) operating system on the server and use
Authentication of the BONE and then, you can connect to SYS AS SYSDBA anyway.
So, in fact, it is not possible to lock SYS even if you run the following:
ALTER USER SYS ACCOUNT LOCK;
If you want to prevent access on SYS, you must set a password long and complex and
apply the same rule for the admin / root user OS.
These passwords must be known very little and well - to identify the people and written nowhere
(in files or scripts).
Plus more, you should restrict DBA role to SYS and SYSTEM and remove this powerful role
other Oracle users.
Then, you can enable the CHECK in order to control the connection to the session database and,.
create a LOGIN TRIGGER to verify the connection, the workstation, the program end-users
that connect to the database.
In 10g, DBConsole EM shows an alert whenever a user is logged on with SYS.
Please find attached, an interesting paper written by Pete Finigan on this topic:

Hope this helps.
Best regards

you are the owner of the HOUSE of the ORACLE, you need to connect. Yes its because of external authentication.
Of course you can not connect the user to the system. Have you tried?2. don't lock the user SYS standard practice? If so, why?
Depends on the security, some cases, a user will be created with DBA roles.

Question about user SYS and ROLES
Hello
When I create a role, such as:
I see that as soon as the role is created, it is automatically granted to the SYS.create role atestrole;
I thought that, given the fact that SYS has already all the privileges system and object in existence, that the automatic grant was superfluous and unnecessary. To test this, I have revoked the role of 'atestrole' of SYS and then tried to give "atestrole" as user SYS to SCOTT. As expected, SYS has been able to give "atestrole" SCOTT.
At this point, it seems that the automatic granting of new roles to SYS does not SYS, being able to do something that he would be able to do otherwise.
Question: SYS automatically grant all newly created roles, cause SYSTEM to have a few abilities that he would or not is superfluous (as seems to be)?
Thank you for your help,
John.
PS: the new roles are automatically awarded to SYS by Oracle itself, it is not something to be done "manually".
Published by: 440bx - 11 GR 2 on 20 Sep, 2010 08:23 - added PS.I don't know if it will clear the cloud or not! but the result is "a user who creates a role is granted also that default role.
So, if you created the ROLE with SYS is authorized for SYS otherwise DO NOT default. See the example below.SQL> conn sys@xe as sysdba Enter password: ****** Connected.

Subsidies granted by user SYS and SYSTEM
Hi all
Please, help me to understand this problem.
I have a few schema named maps_ref where I create a view. (table abc discovers abc01).
Here, I have granted the create view, creates all privs view to maps_ref by linking the SYS as SYSDBA.
He alllowed me to create the view.
As a test, I revoked the privileges by connecting as a SYSTEM and he revoked the privileges granted by SYS as SYSDBA.
Later, of course, I couldn't create the view.
This means that subsidies granted by SYS as SYSDBA resumable system however SYSDBA is then more powerful SYSTEM?
I'm a little confused how it worked? Please explain.
Rgds,
AashishHello

I forget always at the end of the lIve session of Windows before you put it in standby mode, the PC appears and then lock properly said, in response to anything, so I have to do a reboot complete, very annoying.
Also when working within Windows 2011, if you add a lot of attachments to an e-mail, I have often to do and then send it, the list of attachments disappear off the screen, so when you send you do not know really which was transmitted, horrible situation, so you must include send to yourself, then you can check what has been sent. Stupid!.
How can I get rid of these flaws?

By default, the user SYS and SYSTEM are assigned the DEFAULT profile. According to this profile setting (PASSWORD_LIFE_TIME), the password is suppose to be expired every 180 days, but the SYS and system accounts State is OPEN even after 1 year, not EXPIRED. Pls someone clarify this point.
USER NAME CREATED THE ACCOUNT_STATUS PROFILE
------------------------------ --------- -------------------------------- ------------------------------
SYS 24 AUGUST 13 OPEN BY DEFAULT
24 AUGUST 13 OPEN BY DEFAULT
PROFILE RESOURCE_NAME RESOURCE LIMIT
------------------------------ -------------------------------- -------- ----------------------------------------
PASSWORD_LIFE_TIME 180 DEFAULT PASSWORD
1762432 wrote:
When was the last time that someone actually tried to connect as SYSTEM?
--> No not tried until now. This means if try to connect as a SYSTEM, then it gets only EXPIRED remains OPEN even if the PASSWORD_LIFE_TIME stretches limited 180.
Have you read the link I gave you? In particular, the discussion on the fig. 5 and fig. 6.
If you had, you would have the answer to this question.
I thought the account that EXPIRES based on PASSWORD_LIFE_TIME even gets does not attempt to connect DB via the account.
Then, you thought wrong. As I said earlier, the database does not spend time constantly trawling through accounts looking to see if something has passed its expiration date. If she did that, he would never time to do something else. He checks in the context of a connection request and responds
as a result.

The user sys and system can be locked? If so, what is the effect on the database?
My user sys and system database showing has already expired and locke date is null.
Please suggest.
USERNAME LOCK_DATE EXPIRY_DA ------------------------------ --------- --------- ACCOUNT_STATUS -------------------------------- MGMT_VIEW 18-FEB-11 OPEN SYS 18-FEB-11 OPEN SYSTEM 01-MAR-11 OPEN
You need to use or create a profile for which PASSWORD_LIFE_TIME is set to UNLIMITED. It is normally the case for the DEFAULT profile.
Example to use the DEFAULT profile:
SQL> alter user sys profile default; User altered.
For example, to create a profile:
SQL> create profile sp limit password_life_time unlimited; Profile created. SQL> alter user sys profile sp; User altered.
But you must take into account all the resources limits related to the PASSWORD_LIFE_TIME not only profile.

With my new desktop Windows 7 hardware configuration, I decided (before you consider VMware Player) to retry Windows Virtual PC; but instead of using Windows XP Mode (which is useless because the disk is inaccessible), I decided to use my own Windows XP Pro OEM. [I use it for games that won't play on Win7. Security issues are also irrelevant, because for these games, I'm not likely to use the Web. Of course, I always Windows Security Essentials in my OEM customers.]
The problem here is, whenever I have to Activate my integration, features VPC opens as if the Windows XP Mode have been installed (it is not); and when the screen is turned on, it asks my user name and password. I tried to use the name and the password that I entered when installing my XP OEM; but I get this message:
"The system could not log. Make sure that your user name and domain are correct. Type your password again. Letters in passwords must be entered using the proper case. »
How is it that I can't access my Windows XP OEM guest when the integration features are enabled? Only when they are disabled can I activate my OS; invited but it's counterproductive, because I won't be able to move items from my host in my comments. Once more, if I should decide to use VPC as my host VM for Linux Ubuntu/Kubuntu, what chance is there that the activation of the integration features will lock out me my Linux guest?
Another thing: in the Start Menu under Windows Virtual PC folder I have shortcuts for ' Windows Virtual PC ' or 'Virtual Machines' (according to the Win7 version I use, 32-bit or 64-bit); but I also have "Windows XP Mode", I have not installed. How is that possible? I checked the shortcut, and point it to rundll32.exe. Should I just get rid of the shortcut, or I will incur damage to my VPC if I do?

Why is password for SYS and SYSTEM different
I use 10g Express
During the installation I created the password and I use it as a password with SYS, but it does not work with the SYSTEM
(I'm with Windows 7 on AMD x 64)
Thank you.Hello
The SYS and SYSTEM password are asked during the database creation process.
May be that a different password has been set.
Anyway, as you know the password for SYS, you can change the password for the SYSTEM with the following statement:
alter user system identified by

If you want to protect the data dictionary, then use 07_DICTIONARY_ACCESSIBILITY parameter to deny users that has 'SELECT ANY TABLE' privilege to select the data belonging to SYS
And don't forget, if you share the password for user SYS or SYSTEM, it means that you share all the information as data dictionary
