Oracle
Access Manager (Access Manager) is the key capability for Web Single Sign-on
(SSO), authentication, authorization, centralized policy administration and
agent management, real-time session management, and auditing in the new Oracle
Access Management platform. Access Manager is a 100% Java solution that is
incredibly scalable, allowing it to manage Internet-scale installations. It
also works with heterogeneous environments that already exist, with agents
certified for hundreds of web and application servers. Access Manager increases
security, improves user experience and productivity, and improves compliance
while lowering total cost of ownership by providing broad capabilities,
scalability, and high availability.

Fusion Applications interview Questions and Answers
Ques: 1). What are the different security modes available in Oracle Access Manager?
Answer:
Open: Allows communication
without encryption. There is no authentication or encryption between the
AccessGate and the Access Server in Open mode. The AccessGate does not need the
Access Server to provide proof of identification, and the Access Server accepts
connections from all AccessGates. Similarly, Identity Server does not require
WebPass to provide confirmation of identity.
Simple: Oracle encryption is
supported. TLS v1 is used to secure communications between Web clients in
Simple mode (WebPass and Identity Server, Policy Manager and WebPass, and
Access Server and WebGate). Oracle Access Manager components only use X.509
digital certificates in both Simple and Cert modes. The standard cert-decode
plug-in decodes the certificate and delivers certificate information to the
standard credential mapping authentication plug-in in Cert Authentication
between WebGates and the Access Server. Oracle Access Manager saves the
associated private key for each public key in the aaa key.pem file for the
Access Server (or ois key.pem for the Identity Server).
Cert: A third-party certificate
is required. If you have an internal Certificate Authority (CA) for processing
server certificates, use Cert (SSL) mode. Communication between WebGate and
Access Server, as well as between Identity Server and WebPass, is encrypted in
Cert mode utilising Transport Layer Security (RFC 2246). (TLS v1).

Ques: 2).
What Is Oracle Access Manager's Architecture?
Answer:
Identity
Server, WebPass, Policy Manager, Access Server, and a WebGate are the primary
components of the Oracle Access Manager architecture. Identity Server is a
stand-alone C++ server that connects to LDAP directly.
It
also receives requests from Webpass and responds to them. WebPass is a web
server plugin that allows information to be passed between the identity server
and the web server. It sends Identity XML SOAP requests to Identity Server and redirects
HTTP requests from the browser to Access Server.
A web
server plugin called Policy Manager (PMP or PAP) interfaces directly with user,
configuration, and policy repositories. Access Server, commonly known as PDP,
is a stand-alone C++ server. It receives requests from WebGates/AccessGates and
responds to them.
It
also uses LDAP for communication. It responds to queries from the Access Server
SDK. WebGate (PEP) is a web server plugin that communicates with the access
server. It passes user authentication data to access server for processing.

Ques: 3). In Oracle Access Manager, what is the Iwa mechanism?
Answer:
The
OAM offers a feature that allows Microsoft Internet Explorer users to
authenticate to their Web packages using their computing device credentials on
a regular basis. Windows Native Authentication is the term for this. The user logs
in to the computer, and the Windows Domain Administrator authentication
mechanism is used to complete the local authentication.
The
user launches an Internet Explorer (IE) browser and asks a Web assist from the
Access System.
The
browser notifies the IIS Web server about the neighbourhood authentication and
sends a token.
The
token is used by the IIS Web server to authenticate the user and to set the
REMOTE USER HTTP header variable, which indicates the customer name provided by
the customer and authenticated by the server.
The
WebGate creates an ObSSOCookie and sends it lower back to the browser.
The
Access System authorization and different techniques proceed as usual.
The
maximum session timeout length configured for the WebGate is applicable to the
generated ObSSOCookie.

4). What Is An Access Server Sdk?
Answer
:
The
Access Manager Software Developer's Kit (SDK) allows you to extend the Access
System's access management features. You can use this SDK to construct a
customised AccessGate. The Access Manager SDK provides an environment in which
you can establish an AccessGate by creating a dynamic link library or a shared
object. You'll also need configureAccessGate.exe to make sure your client is
working properly.

Oracle Financials Interview questions and Answers
Ques: 7). What is IIS?
Answer:
Internet
Information Services (IIS, formerly Internet Information Server) is a Microsoft
extensible web server designed for use with the Windows NT family of operating
systems. [2] HTTP, HTTPS, FTP, FTPS, SMTP, and NNTP are all supported by IIS.
Since Windows NT 4.0, it has been a fundamental element of the Windows NT
family, albeit it may be missing from other editions (e.g. Windows XP Home
edition). When Windows is installed, IIS is not enabled by default. The IIS
Manager can be accessed through the Control Panel's Microsoft Management
Console or Administrative Tools.
Oracle Cloud Interview Questions and Answers
Ques: 8). What is the meaning of an Oracle Access Manager Basic License?
Answer:
The
Oracle Access Manager (OAM) Basic licence was intended to support Oracle AS
Single Sign-On (OSSO) customers who purchased the Oracle iAS Suite or other
Oracle E-Business Suite products. Customers who have valid Oracle Single
Sign-On (OSSO) licences can swap them for an equivalent number of Access
Manager licences under the OAM Basic licence, with some restrictions. Access
Manager must employ Oracle infrastructure components due to the constraints;
this was also a requirement for OSSO. The LDAP directory, for example, must be
Oracle Internet Directory or Oracle Virtual Directory, and only Oracle
application resources can be protected. Customers who want to remove the
restrictions must acquire the complete Access Manager licence.
Oracle PL/SQL Interview Questions and Answers
Ques: 9). What is Oracle Webgate, and how does it work?
Answer:
Oracle
WebGate is a Web server plug-in that comes with Oracle Access Manager out of
the box. Users' HTTP requests for Web resources are intercepted by the WebGate
and forwarded to the Access Server for authentication and permission.

Interview Questions and Answers
Ques: 10). 11g Access Manager Oracle HTTP Server 11g and IBM HTTP Server 7.0 support WebGates, but I prefer Apache Web Servers. If I want to use Access Manager 11g, what should I do?
Answer:
Oracle
Access Manager 10g WebGates can communicate with Access Manager 11g servers.
Oracle Access Manager 10g WebGates have a wide range of web server
certifications, including Apache, Domino, Microsoft IIS, and many others. With
thousands of applications, I have a massive Oracle Access Manager 10gR3
implementation. Do I have to transfer them all at once to the new 11gR2
platform? No. Both Oracle Access Manager 10gR3 and Oracle Access Manager 11gR2
servers can be live in production at the same time, protecting distinct sets of
applications, thanks to server side coexistence in Access Manager 11gR2. End
users will continue having a seamless single sign-on experience as they
navigate between applications protected by the two servers. This capability can
be leveraged by customers with large deployments to perform the server
migration in a phased manner over a period of time without impacting end users.
Oracle RDMS Interview Questions and Answers
Ques: 11). With thousands of applications, I have a massive Sun Access Manager 7.1 or Sun Access Manager 7.1 deployment. Is it necessary to migrate all of them to the new Access Manager 11gR2 platform at the same time?
Answer:
No.
Both the OpenSSO 8.0 (or Sun Access Manager 7.1) and Access Manager 11gR2
servers can be live in production at the same time safeguarding distinct sets
of apps with Access Manager 11gR2. End users will continue to have a seamless
single sign-on experience as they move between the two servers' protected apps.
Customers with big deployments can utilise this capability to migrate servers
in stages over time without affecting end users.
BI Publisher Interview Questions and Answers
Ques:
12).What Is An Identity Xml?
Answer:
IdentityXML
provides a programmatic interface for performing the actions that a user can
perform while using a browser to access a COREid application. A software can,
for example, submit an IdentityXML request to find members of a group defined
in the Group Manager software or to add a person to the User Manager. Simple
moves and multi-step procedures can be applied to trade person, institution,
and company object profiles using IdentityXML. After you've finished
constructing the IdentityXML request, you'll need to put up a SOAP wrapper to
send the IdentityXML request to WebPass over HTTP. XML over SOAP is used by the
IdentityXML API. Using an HTTP request, we send IdentityXML parameters to the
COREid Server. A SOAP envelope is included in this HTTP request. When WebPass
receives an HTTP request, the SOAP envelope identifies it as an IdentityXML
request rather than a standard browser request. The request is passed to the
COREid Server, which executes the request and returns a response. You could
also use WSDL to put together the SOAP request. This appears to be the SOAP
content material: SOAP envelope (with oblix namespace described), SOAP body
(with authentication information), genuine request (with software name and
params). Userservcenter, groupservcenter, or objservcenter are examples of
application names (for companies).
Oracle 10g Interview Questions and Answers
Ques:
13). What are Header Variables and How Do I Use Them?
Answer:
The
Header Variable contains Oracle Access Manager allows administrators to build a
web of trust in which a user's credentials are confirmed once and then
delivered to each application that the user uses. The programme does not need
to re-authenticate the user with its own mechanism when using these
credentials. Users who have been authenticated by Oracle Access Manager are
able to access applications without having to re-authenticate. A user's
credentials can be sent in one of two ways:
•
Using Cookies: A specific value is set on the browser's cookie that the
application must extract to identify a user.
•
Using Header Variables: An HTTP header set on the request by the agent and
visible to the application. Authorization Policy Response in the Administration
Console Header response values are inserted into a request by an OAM Agent, and
can only be applied on Web servers that are protected by an agent registered
with OAM 11g If the policy includes a redirect URL that is hosted by a Web
server not protected by OAM, header responses are not applied.
Ques:
14). Explain the Oam-oaam Integration Architecture and Integration.
Answer:
Using
all of these products together will provide you complete control over the
authentication process and comprehensive pre-/post-authentication testing
capabilities against Adaptive Risk Manager models.
Two
Oracle Access Manager AccessGates are used in the OAAM's ASA-OAM integration:
one for fronting the Web server (a traditional WebGate) to Adaptive Strong
Authenticator and one for the embedded AccessGate. The access server SDK must
be installed and configured before the AccessGate device can be used. The ASDK
location will be updated in the ASA bharosa papers. An application that will
use the ASA authentication mechanism and will be tested for the ASA login
touchdown page.
Ques:
15). What Happens When A User Submits A Request That Is Protected By An Access
Gate (No Longer Webgate)?
Answer:
The
following is an example of the flow:
The
consumer sends a resource request to the application or servlet that has the
access gate code.
The
access gate code creates an ObResourceRequest shape and calls the Access server
to determine whether or not the resource is protected.
The
server responds to the request for entry. If the aid isn't secured, gaining
access to the gate allows anyone to gain access to the resource. Otherwise,
Access Gate creates an ObAuthenticationScheme shape to inquire about the
credentials the user wishes to send to Access Server. The request for entry to
the server is granted. To get the credentials, the programme employs a form or
one of several additional methods. The AccessGate creates the ObUserSession structure,
which provides the Acc Server with user information. If credentials are
verified valid, get admission to gate creates a session token for the person
after which sends an authorization request to the get admission to server.
Access server validates if the user is authz to get right of entry to that
useful resource. Access gate permits user to get entry to the asked resource.
Ques:
16). What exactly is SSO?
Answer:
SSO
(single sign-on) is a session/user authentication method that allows a user to
access different apps with just one username and password. The procedure
authenticates the user for all of the programmes to which they have been
granted access and removes the need for further questions when they switch
applications during a session.
Overview:
- Provides users with
unified sign-on and authentication across all their enterprise resources,
including
- desktops,
client-server, custom, and host-based mainframe applications
- Provides a centralized
framework for security and compliance enforcement
- Eliminates the need
for multiple usernames and passwords
- Helps enforce strong
password and authentication policies.
- Uses any LDAP
directory, Active Directory, or any SQL database server as its user
profile and credential repository
Benefits
- Reduces deployment
risk and operational costs.
- Allows enterprises to
provide fast, secure access to applications for employees and partners.
- Eliminates the
overhead and limitations of traditional desktop client deployments.
- Seamlessly integrates
with Oracle Identity Management for common security policy enforcement
and compliance reporting across applications
Ques:
17). What is Reverse Proxy?
Answer:
A reverse
proxy gives you architectural flexibility by allowing you to expose the same
application on both the intranet and the extranet without having to make any
changes to the existing application. By sending all requests through the proxy,
you may safeguard all Web content from a single logical component.
This
is true even for platforms that Oracle Access Manager does not support. All
content on these servers can be safeguarded if you have multiple types of Web
servers, such as iPlanet, Apache, and others, running on different platforms,
such as MacOS, Solaris x86, mainframe, and so on. A reverse proxy can be used
as a workaround for unsupported Web servers, removing the requirement to
develop custom AccessGates for unsupported Web servers or systems that do not
support AccessGates. This creates a single management point. You can manage the
security of all of the Web servers through the reverse proxy without
establishing a footprint on the other Web servers.
Ques:
18). What is Identity Store and how does it work? Describe the many types of
identity stores.
Answer:
The
term "identity store" refers to a database that contains business
users and groups. Weblogic includes an inbuilt LDAP that is used as the
identity store by default by fusion middleware components. External LDAP
servers, such as OID, AD, and others, can be configured to serve as identity
stores.
System
Store -
Represents the identity store which will have groups or users that will act
as “Administrators” to OAM that is only members of this identity store
group/user can perform admin functions via oam console.
Default
Store - This
will be the identity store that will be used at time of patching for migration
purpose or by Oracle security token service.
Ques:
19). In OAM, what are Authorization Policies?
Answer:
The
process of assessing whether a user has the permission to access a requested
resource is known as authorization. Administrators can establish the
circumstances under which a subject or identity has access to a resource by
creating one or more authorization policies. A user may seek to view data or
run a policy-protected application programme. The requested resource must be
part of an application domain and be covered by a specified permission policy
within that domain.
Ques:
20). In comparison to the ECC, what are the benefits of the DCC?
Answer:
From a
security and flexibility standpoint, the DCC has several advantages. The DCC
can be placed anywhere in the DMZ because it is totally detached from the
Access Manager server. It also adds security by terminating all unauthenticated
end user login requests at the DCC in the DMZ, isolating the server from
unauthenticated network traffic.
