Talk21 - moving to security model of Yahoo

Hi there,
I wonder if anyone can advise on this. I have an older Talk21 e-mail account which has been transferred to Yahoo. I've had this for over 10 years.
I notice when new customers sign up to Yahoo, there are now more advanced security options such as special characters in password, customised secret questions, credit card verification for password recovery and Log-in Activity.
I'd be interested to improve the security of my account using these methods.
Is there any way I can get these on my talk21 account, or is there a possibility of moving my talk21 account to the new security model of Yahoo?
Thanks

Hi Jon.
Not sure if this is applicable to BTinternet/Talk21 email addresses, as opposed to actual Yahoo! ones.
However in case you were unaware, Talk21 email addresses can be accessed as a BTinternet email address as follows.
If you append .t21 (including the dot) after the bit of the Talk21 email address before the @, and then added @btinternet.com at the end, it will be treated as a BTinternet email address.

Java update (3 days ago) won't let me play yahoo games anymore. I've tried moving java security to Medium and adding web address as "permissive use". Still nothing. I'd really like a fix. Really, apple? What's your beef with yahoo games?

Installed Java update three days ago. Now, can't play yahoo games as it's now blocked by security settings. Already have tried moving Java security to Medium and adding yahoo.games.com (including web address of game) as a "Permissive exception". Also tried removing java and installing older version. Still nothing. Really Apple?!? What's your beef with yahoo games?

csnorth,
all of the older update versions of Java SE 7 can be found here. If 7u45 also didn’t work with your Yahoo! games, you can choose from any of the even older versions there as well.

Hi,
Steps Done
1)     Imported the BIPSiebelSecurityWS.XML
2)     Replaced Existing address with the specific address of the Siebel Server
3)     Enabled Local Super user checkbox, entered a Super user name and password
4)     Configured the Siebel Security Model by pointing the Siebel Web Service end point with Siebel Username/Pwd
5)     Restarted the Bipublisher
6)     When I try to login to Bi Publisher with Siebel Credentials I am getting the error
The server cannot be used due to configuration error, please contact admin..
Please let us know the necessary steps ..

Login using the credentilas used for super user. Siebel user do not work here, it will only fetch the responsibilities here as a roles for that super user.

BIP: Upload error (Invalid BI Publisher Security model SBL-RPT-50532)

Hi, We have Siebel 8.1.1.5 running and having trouble integrating with BI Publisher 10.1.3.4.2 . I have setup and configure BIP as per the instructions.
When we try to upload reports from Reports - Standard Templates View, getting the following error messages:
Invalid BI Publisher Security Model Setting (SBL-RPT-50532) && Error (null) invoking method (null) for business service (null).
I have setup the security model to siebel in BIP and able to login tot he console using SADMIN/SADMIN. All the required components are also online and updated the params as per the instructions.
Any help would be greatly appreciated. Thanks in advance!

Hi Hakan,
Please check whether your EAI Object manager is using different srf to one that application set to. In that case try to
set the EAI to same srf Or compile report stuff to that particular srf. And befiore that have you declared the Siebel securiy model setting in BIP.
Please reach me at [email protected] for any issues.
Thanks,
Ravi

Java Security Model: Java Protection Domains

1.     Policy Configuration
Until now, security policy was hard-coded in the security manager used by Java applications. This gives us the effective but rigid Java sandbox for applets.A major enhancement to the Java sandbox is the separation of policy from mechanism. Policy is now expressed in a separate, persistent format. The policy is represented in simple ascii, and can be modified and displayed by any tools that support the policy syntax specification. This allows:
o     Configurable policies -- no longer is the security policy hard-coded into the application.
o     Flexible policies -- Since the policy is configurable, system administrators can enforce global polices for the enterprise. If permitted by the enterprise's global policy, end-users can refine the policy for their desktop.
o     Fine-grain policies -- The policy configuration file uses a simple, extensible syntax that allows you to specify access on specific files or to particular network hosts. Access to resources can be granted only to code signed by trusted principals.
o     Application policies -- The sandbox is generalized so that applications of any stripe can use the policy mechanism. Previously, to establish a security policy for an application, an developer needed to implement a subclass of the SecurityManager, and hard-code the application's policies in that subclass. Now, the application can make use of the policy file and the extensible Permission object to build an application whose policy is separate from the implementation of the application.
o     Extensible policies -- Application developers can choose to define new resource types that require fine-grain access control. They need only define a new Permission object and a method that the system invokes to make access decisions. The policy configuration file and policy tools automatically support application-defined permissions. For example, an application could define a CheckBook object and a CheckBookPermission.
2.     X.509v3 Certificate APIs
Public-key cryptography is an effective tool for associating an identity with a piece of code. JavaSoft is introducing API support in the core APIs for X.509v3 certificates. This allows system administrators to use certificates from enterprise Certificate Authorities (CAs), as well as trusted third-party CAs, to cryptographically establish identities.
3.     Protection Domains
The central architectural feature of the Java security model is its concept of a Protection Domain. The Java sandbox is an example of a Protection Domain that places tight controls around the execution of downloaded code. This concept is generalized so that each Java class executes within one and only one Protection Domain, with associated permissions.
When code is loaded, its Protection Domain comes into existence. The Protection Domain has two attributes - a signer and a location. The signer could be null if the code is not signed by anyone. The location is the URL where the Java classes reside. The system consults the global policy on behalf of the new Protection Domain. It derives the set of permissions for the Protection Domain based on its signer/location attributes. Those permissions are put into the Protection Domain's bag of permissions.
4.     Access Decisions
Access decisions are straightforward. When code tries to access a protected resource, it creates an access request. If the request matches a permission contained in the bag of permissions, then access is granted. Otherwise, access is denied. This simple way of making access decisions extends easily to application-defined resources and access control. For example, the banking application allows access to the CheckBook only when the executing code holds the appropriate CheckBookPermission.
Sandbox model for Security
Java is supported in applications and applets, small programs that spurred Java's early growth and are executable in a browser environment. The applet code is downloaded at runtime and executes in the context of a JVM hosted by the browser. An applet's code can be downloaded from anywhere in the network, so Java's early designers thought such code should not be given unlimited access to the target system. That led to the sandbox model -- the security model introduced with JDK 1.0.
The sandbox model deems all code downloaded from the network untrustworthy, and confines the code to a limited area of the browser -- the sandbox. For instance, code downloaded from the network could not update the local file system. It's probably more accurate to call this a "fenced-in" model, since a sandbox does not connote strict confinement.
While this may seem a very secure approach, there are inherent problems. First, it dictates a rigid policy that is closely tied to the implementation. Second, it's seldom a good idea to put all one's eggs in one basket -- that is, it's unwise to rely entirely on one approach to provide overall system security.
Security needs to be layered for depth of defense and flexible enough to accommodate different policies -- the sandbox model is neither.
java.security.ProtectionDomain
This class represents a unit of protection within the Java application environment, and is typically associated with a concept of "principal," where a principal is an entity in the computer system to which permissions (and as a result, accountability) are granted.
A domain conceptually encloses a set of classes whose instances are granted the same set of permissions. Currently, a domain is uniquely identified by a CodeSource, which encapsulates two characteristics of the code running inside the domain: the codebase (java.net.URL), and a set of certificates (of type java.security.cert.Certificate) for public keys that correspond to the private keys that signed all code in this domain. Thus, classes signed by the same keys and from the same URL are placed in the same domain.
A domain also encompasses the permissions granted to code in the domain, as determined by the security policy currently in effect.
Classes that have the same permissions but are from different code sources belong to different domains.
A class belongs to one and only one ProtectionDomain.
Note that currently in Java 2 SDK, v 1.2, protection domains are created "on demand" as a result of class loading. The getProtectionDomain method in java.lang.Class can be used to look up the protection domain that is associated with a given class. Note that one must have the appropriate permission (the RuntimePermission "getProtectionDomain") to successfully invoke this method.
Today all code shipped as part of the Java 2 SDK is considered system code and run inside the unique system domain. Each applet or application runs in its appropriate domain, determined by its code source.
It is possible to ensure that objects in any non-system domain cannot automatically discover objects in another non-system domain. This partition can be achieved by careful class resolution and loading, for example, using different classloaders for different domains. However, SecureClassLoader (or its subclasses) can, at its choice, load classes from different domains, thus allowing these classes to co-exist within the same name space (as partitioned by a classloader).
jarsigner and keytool
example : cd D:\EicherProject\EicherWEB\Web Content jarsigner -keystore eicher.store source.jar eichercert
The javakey tool from JDK 1.1 has been replaced by two tools in Java 2.
One tool manages keys and certificates in a database. The other is responsible for signing and verifying JAR files. Both tools require access to a keystore that contains certificate and key information to operate. The keystore replaces the identitydb.obj from JDK 1.1. New to Java 2 is the notion of policy, which controls what resources applets are granted access to outside of the sandbox (see Chapter 3).
The javakey replacement tools are both command-line driven, and neither requires the use of the awkward directive files required in JDK 1.1.x. Management of keystores, and the generation of keys and certificates, is carried out by keytool. jarsigner uses certificates to sign JAR files and to verify the signatures found on signed JAR files.
Here we list simple steps of doing the signing. We assume that JDK 1.3 is installed and the tools jarsigner and keytool that are part of JDK are in the execution PATH. Following are Unix commands, however with proper changes, these could be used in Windows as well.
1. First generate a key pair for our Certificate:
keytool -genkey -keyalg rsa -alias AppletCert
2. Generate a certification-signing request.
keytool -certreq -alias AppletCert > CertReq.pem
3. Send this CertReq.pem to VeriSign/Thawte webform. Let the signed reply from them be SignedCert.pem.
4. Import the chain into keystore:
keytool -import -alias AppletCert -file SignedCert.pem
5. Sign the CyberVote archive �TeleVote.jar�:
jarsigner TeleVote.jar AppletCert
This signed applet TeleVote.jar can now be made available to the web server. For testing purpose we can have our own test root CA. Following are the steps to generate a root CA by using openssl.
1. Generate a key pair for root CA:
openssl genrsa -des3 -out CyberVoteCA.key 1024
2. Generate an x509 certificate using the above keypair:
openssl req -new -x509 -days key CyberVoteCA.key -out CyberVoteCA.crt
3. Import the Certificate to keystore.
keytool -import -alias CyberVoteRoot -file CyberVoteCA.crt
Now, in the step 3 of jar signing above, instead of sending the request certificate to VeriSign/Thawte webform for signing, we 365 - can sign using our newly created root CA using this command:
openssl x509 -req -CA CyberVoteCA.crt -CAkey CyberVoteCA.key -days 365 -in CertReq.pem -out SignedCert.pem �Cacreateserial
However, our test root CA has to be imported to the keystore of voter�s web browser in some way. [This was not investigated. We used some manual importing procedure which is not recommended way]
The Important Classes
The MessageDigest class, which is used in current CyberVote mockup system (see section 2), is an engine class designed to provide the functionality of cryptographically secure message digests such as SHA-1 or MD5. A cryptographically secure message digest takes arbitrary-sized input (a byte array), and generates a fixed-size output, called a digest or hash. A digest has the following properties:
� It should be computationally infeasible to find two messages that hashed to the same value.
� The digest does not reveal anything about the input that was used to generate it.
Message digests are used to produce unique and reliable identifiers of data. They are sometimes called the "digital fingerprints" of data.
The (Digital)Signature class is an engine class designed to provide the functionality of a cryptographic digital signature algorithm such as DSA or RSA with MD5. A cryptographically secure signature algorithm takes arbitrary-sized input and a private key and generates a relatively short (often fixed-size) string of bytes, called the signature, with the following properties:
� Given the public key corresponding to the private key used to generate the signature, it should be possible to verify the authenticity and integrity of the input.
� The signature and the public key do not reveal anything about the private key.
A Signature object can be used to sign data. It can also be used to verify whether or not an alleged signature is in fact the authentic signature of the data associated with it.

Need Best Practice - Apex, multiple schemas, security model

We have an oracle database which contains
a) named database users with no objects
b) several schemas with data tables:
sales
marketing
accounting
We need to build GUI for tables in these schemas,
every database users should belong to a group, each user group should have access to several (not all) GUI pages.
1) Is it possible and is it recommended (if not - why?) to create ONE workspace and ONE application inside it to have access to ALL tables in ALL schemas listed with user groups level security?
How to do it properly?
Some link to documentation?
2) Which security model (apex users, database users,..) to choose and why? please recommend some links to comparison...

Hi Marcus,
Our developers like to see all the tables for a single custom application in its own diagram no matter where they come from and the DBA's don't want to wade through several thousand tables to find the handful we need nor have to duplicate table definitions in multiple models. In >Designer we have been doing that with Application Folders.There are no application folders in data Modeler. You can use subviews to define your subject areas. Subview is crated for each application (folder) during import form Designer repository.

CRM 7.0 security model & accessebility of data at table level

Hi CRM Experts,
Firstly i am new to this topic 'CRM 7.0 security model' and i want following information from you, my simple requirement of my on going project.
1. what are different types of roles in CRM 7.0 system and how to define those roles & which table all the role information is stored in CRM 7.0 ABAP & Java stack installled system.
2. How are the ABAP & JAVA roles are different from each other in CRM 7.0 system.
3. How to define portal roles in CRM 7.0 & which table or storage location these portal roles data are stored & is there any way we can extract them from CRM system, if any webservice or any mean this can be achieved?
Basically i am interested in users/roles/authorization data in CRM 7.0 for both ABAP & JAVA stack system. please help me achieving this requirement.
Thanks,
Digamber.

Digamber,
For an overview of the changes in CRM 7.0, visit the following link:
http://www.sap.com/germany/solutions/business-suite/crm/SAP_CRM7_Highlights.pdf
In respect to Security model, CRM 7.0 is a bit different, where a lot of functionality is executed via BSPs that are run on a browser. However, the authorizations should be still need to assign in the the backend.
For CRM specific security guides, I recommend you visit the SAP link - http://service.sap.com/security
In the left pane hierarchy, go to 'Security Guides'. Scroll down to find the CRM section and download the required guides.
Also, further there are new concepts like WEBCLIENT UI (an extra authorization layer, which is UI COMPONENT LEVEL and logical links. (Controlled by object UIU_COMP)). Standard authorization setup in the new WEBUI client is now controlled by both backend authorizations and the UIU_COMP. That means even if the user has SAP_ALL access, he will not able to perform any actions.
Hope this provides some light!!

Assigning role to role doesn't work when applying Database security model

I applied Oracle Database security model for BI Publisher.
then I create some roles and users and assigned roles to users in Oracle Database.
i also assigned appropriate folders to each role in BI Publisher.
the users with direct roles worked successfully but i got problem when i assigned roles to a super role, and assigned this role to a super user.
the super user could only access guest folder.
Please help me.
thanks.
Daniel

Add a Role to a Role:
1. From the Security Center, select Roles and Permissions; this will invoke the
Security Center page. Here you can see the list of existing roles and permissions.
2. Select the Add Roles icon for the Role.
3. Select the desired role from the Available Roles list and use the Move shuttle
button to move it to the Included Roles.
this is from "Oracle® Business Intelligence Publisher User's Guide Release 10.1.3.2 Part No. B40017-01" book, but the security model is BI Publisher Security.

Andre,
It seems you are using the URL
jndi:t3://secuser1:[email protected]:7131/AccountDelegatorEJB
whereas you should not be specifying the "t3:" protocol.
The URL should be like
jndi://secuser1:[email protected]:7131/AccountDelegatorEJB
Please do let me know if you see any issues with this.
Note that this will only allow you to access remote EJBs in the same WLS
domain. For accessing EJBs on another domain, you need to configure
inter-domain communication by
following a few simple steps as mentioned at
http://e-docs.bea.com/wls/docs81/ConsoleHelp/jta.html#1106135. This link has
been provided in the EJB Control Workshop documentation.

Can you try using the following url with username and password

once you add webapp level security, the authenticated is the user who

Advice on Security Model Architecture..

Hi all,
Just looking for the advice of the experts :)
I am working on the security model architecture for multi-tiered java application. The application architecture breaks down roughly as follows:
Presentation Layer (JSP/Java)
Business Layer (Java)
Persistence Layer (JDBC/Oracle DB)
Now, in the DB we will preserve information about various users, as well as the user's application permissions. My question pertains to authentication/authorization. Where is it most appropriate or efficient to verify a user's access to a functionality? Assume that the user and permission information is retrieved upon login and is made available to all levels.
The options, as I see them, include the following:
Presention layer - UI exposes only functionality applicable to the user.
Business layer - Encode the logic in this facade for the backend.
Persistence layer - Encode the logic in the data access objects.
Any thoughts?

Well, the layered approach is one way in which java applications are constructed.. the user interface is the top layer, which is composed of jsp files and other java files, and the objects that talk to the database are the bottom layer. Maybe an example would help..
You're looking at a page on the Java Discussion Forums. It's a jsp page. You click on the 'Watches' link (upper right). The link points to a servlet, which calls a method in an object that is in what I call the "business" or middle layer/tier. An object in this layer has methods that correspond to any request that needs to be made of the db.
This method in turn calls method/methods in the backend, or data layer, which queries the database and returns the watches for this particular user...
So, if you have a request/response transaction (click on a link or button, processing, and new page is loaded), it would make a round trip through the layers:
Presentation -> Business -> Data -> DB -> Data -> Business -> Presentation

Migrate to the Java 2 security model instead...

Since I installed Java 4 ver 1.4 on my computer, I have not been able to access my homebanking. In the Java console I get the following message:
1.4.0 on Windows XP
Netscape security model is no longer supported.
Please migrate to the Java 2 security model instead.
What does it mean, and how do I fix the problem???
Thanks in advance!

This is a real pain. I can't roll out Java 1.4 inside our company because we use several applets for which we do not have the source code, and they no longer work because of this limitation. Sun needs to fix this if they want people to upgrade to Java 1.4.

Migrate to the Java 2 security model

Hi, I've tried to use signed applets but I always get the following message:
Java (TM) Plug-in: Version 1.3.1_02
Netscape security model is no longer supported.
Please migrate to the Java 2 security model instead.
Netscape security model is no longer supported.
Please migrate to the Java 2 security model instead.

I'm using IExplorer 5.5 with the Java Plug-In 1.3.1_02.
What does it mean 'migrate to the Java 2 security model'?
How can I migrate?
thanks in advance.

So you mean your applet is working in Netscape 6.2 after editing prefs.js. In that case, one possible solution is take away the support of netscape.security.* in your applet . Because netscape.* packages 'might' use the Netscape Security model, which is no longer supported(check out). Hence the system asks you to migrate to the current java security model. Even if you remove the netscape.* support, your applet will work, if you have signed it properly. In that case, you don't have to touch prefs.js or java.policy or anything from your client machine.(provided you use standard certificates like verisign).
Since you have only class file of the applet and not the source, decompile the class file and make the alteration and compile it back. A decompiler Jad is available here http://midlet.org/jsp/category.jsp?parentLevel=137.
Let me know if this has helped you.

Netscape vs. Java 2 Security model

Hi, new user here, downloaded and installed Java Virtual Machine plug-in, 1.4.2-b28, Wednesday evening. Added Java capability to IE 6.0.28. Running XP.
Encountered a problem with a URL that had worked with Microsoft VM on another machine on my home network. Found the Java Console, which gave the following message: "Netscape security model is no longer supported. Please migrate to the Java 2 security model instead."
Questions:
1) Might this be the source of the problem I encountered?
2) Is the Java 2 security model something I have to download, or is it some setting in IE?
3) If this isn't the right forum for this question, which one is?
That is, how do I "migrate" to Java 2, and why would I be using a Netscape Security model with the latest version of IE?
I am not a developer, just a frustrated consumer!
Warmest regards

dear sir
I am having the same problem as yours did you find a soloution for this problem
Thanks & best regards
