This will take user to new window and user without actually typing user name password can re-login to Apps. How to avoid this situation? Execute ssogito.

There are few more steps on SSO server which you can find in link below. We are facing a problem where customer is getting oracle timeout screen after 30 minutes. Proposed solution- they want an alert message to come on Oracle timeout screen by which they can go to Gate keeper screen.

Can anyone please suggest me how to implement the same. It is presently tracked by bug Bug. SSO Global Inactivity time-out GITO also has a known restriction that it does not work automatically for dynamically protected pages, as all pages are on R12 which is dynamically protectedunless each page check for expiration. Hence, there still needs to be a relative Apps code to consume this SSO timeout. My developers did one hibernate application.

For that we need to set DB session time out. For this what i have to do? Please help me out. This is very urgent for me. Did you find a solution to your problem? I am facing the same challenge.

Even regular web applications have these issues. People can easily alter or inject javascript code on a page through the developer console. Mobile apps, such as those on Android and iOS, can be decompiled and inspected. As such, you would not want to embed sensitive information like secret keys or passwords in these types of clients.

In this post, I will cover some of the best techniques to secure webapps and how to handle the pitfalls with those approaches. This post applies to all modern programming languages.

The primary goal of web application security is to prevent malicious code from running in our applications. We want to ensure user credentials are sent to our servers in a secure way. We want to secure our API endpoints. As a bonus, we want to expose access control rules to the client. XSS attacks occur when a vulnerable application allows arbitrary javascript code to be injected and executed on your page.

This often occurs through the form fields on the page. In the clip below, you can see this behavior in action.


This is taken from the app security live example page. I put script tags into the search field of the page form. Since this site is not protected against XSS attacks, it goes ahead and executes that script code, resulting in the alert popup. In a nutshell, the remedy for XSS is to escape all user input. On the cheatsheet referenced above, there are links to a number of XSS protection libraries.

You could miss vectors of attack or even introduce new ones writing your own escaping library. Traditionally, users enter their authentication information in the form of a username and password and transmit that information up to the application server hopefully in a secure fashion as an HTTP POST. Assuming the credentials are correct, the application server creates a unique session id to identify the user and sends it back in the form of a Set-Cookie header on the response.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Periodically less than 30 minutesthe website will attempt to re-authenticate the user with the STS. This would be fine, however the web application is built as a single page aplication so we never reload the page once it is loaded.

Furthermore, the reauthentication request often occurs during an ajax call. Regarding bthe setting you want is the Token Lifetime. As for athe only method I know of is to catch the exception that is thrown by the ajax call and refresh your single page.

Technical site integration observational experiment live on Stack Overflow.Categorized: Access and Authentication Articles. A single-page application SPA is a web application or web site that interacts with the user by dynamically rewriting the current page rather than loading entire new pages from a server.

This approach avoids interruption of the user experience between successive pages, making the application behave more like a desktop application. Source Wikipedia. Common frameworks include React and Angular.

There are at least two schools of thought for authentication with an SPA, either using the existing Web Session via Cookies, or using an API approach using authentication tokens. When using a Session Cookie in a browser, an SPA should require minimal changes to operate through ISAM — with the authenticated state being handled by the standard cookie jar.

The only catch is handling the session timeout and other ISAM responses gracefully. Fortunately, there are a few handy settings to help you do this. Initially an SPA may be loaded from either an authenticated or unauthenticated state — depending on your configured ACLs. See the the Knowledge Center KC entry here for more information on the [rsp-header-names] stanza.

ISAM can be configured to return the operation of a login event as a custom header. This significantly improves the ability to detect in JavaScript a timeout event. In ISAM 9. The full documentation in the KC is detailed here. These can be easily parsed by JavaScript if necessary to extract critical information. See the KC entry here for more information about the enable-html-redirect setting.

See the KC entry here for more information about the preserve-inactivity-timeout setting. Under some circumstances and for some clients, operating with an authentication token can be desirable.

This guide will focus on the use of OAuth 2. In general, when actively using different authentication mechanisms for your API requests token AND cookie for examplethere are benefits to hosting two separate Reverse Proxies. This allows for more customisation on the responses you return to the different calling clients. In either case however — many of the suggestions above for a cookie based approach can still be useful for identifying and handling session timeouts and error events.

Deploying OAuth in this context is quite different to the traditional 3-legged-OAUTH flow, because the OAUTH client is now the same entity as the user-agent, and the authorization server can be the same entity as the resource server. The OAuth implicit flow returns tokens directly from the authorization request, making it the historical method for an in the browser OAUTH client to get bearer tokens to use to for accessing APIs.

It does however have other security concerns around token leakage. When making the request for the token, an authenticated web session is required, or the user directed to login.

This enables ISAM to more appropriately respond to authentication challenges suiting the client requests.

For example the application might be hosted on AWS, making use of an ISAM hosted on-premise or in another enterprise controlled data center. An example of this is shown below:. When a token is received, you can capture the token expiry period. Keeping track of this timeout in your SPA allows you to preemptively handle a timeout gracefully, before API requests are rejected.

Use short lived access tokens within your SPA, requiring a new token before your web session expires, which will prevent unexpected prompts for authentication with continued use. See this article here for more information. In many of the diagrams above, we make use of ISAM as the Reverse Proxy protecting the resource server, but this is by no means critical to the deployment.

There are also patterns where the tokens may be opaque or JWT based, or a combination of both. Using the flexibility and dynamic authentication capabilities of ISAM in conjunction with the API Gateways capabilities to get the best of both worlds. Where the token is not JWT based, the pattern can be consumed via token introspection at the gateway, and Leo has prepared a great technical article here:.Sounds like a good thing — in principle. Session timeout defines an action window which represents the time span in which an attacker can try to steal and use an existing user session.

Session expiration is mandatory unless you want to give an attacker unlimited time to guess or brute-force a valid session token. You definitively need to acknowledge that a session token, for example a cookie, represents your credentials for accessing protected content. During the time of its validity the token is as confidential and worth protecting as username and password itself. This becomes particularly critical if the transport of tokens is in clear, only secured by weak encryption, in shared environments or if you take into account that session tokens can potentially be logged by servers or proxy servers.

Sounds unrealistic? Think of the situation when you go for a meeting and leave you laptop unlocked. Someone can easily access your browser, retrieve cookie information, and go back to his own computer impersonating you. In that case the best prevention would be locking the screen or manually logging out before leaving.

But, in the rare case we forgot to lock the screen, an idle timeout would mitigate the risk of cookie theft. If the attacker steals the cookie, say 20 min after you left your desk, an idle timeout of 15 min would have saved you and your data. OddJob infected Firefox and Internet Explorer stealing session identifiers of online banking applications, intercepting manual logout commands from the user, hijacking sessions and keeping them alive by sending periodic requests to the server.

Ending up with access to banking account information and transactions for a long time. And what is the impact to session timeouts? Forcing the use of export-grade crypto means a downgrade in key length to a bit. If your session lasts longer than 7. An absolute timeout shorter than 7. Coming back to the point: Session expiration should be used to make your systems more secure.

More secure, in the context here, means giving the attacker less time to break your safeguards. Please note: Invalidating sessions after timeout or logouts must be done on the client and server side. The latter is the most relevant and mandatory from a security perspective.

Removing the session identifier e. Manual session expiration: Provide an easily accessible logout button, so that the user has the ability to logout and end the session whenever his work is finished or paused. Unfortunately nowadays in many social applications the logout button is hidden somewhere to keep the users logged in. Idle Timeout: Most applications implement idle timeouts which terminate a session after a certain amount of inactivity.

The length of an idle timeout heavily depend on the kind of application. According to OWASP common idle timeouts for high-value applications are minutes, medium critical applications minutes and low risk applications approx. Absolute Timeout: A timeout after which a session is closed no matter there is user activity or not. The absolute timeout limits the time a hijacked session can be used.We will cover access tokens, how they differ from session cookies more on that in this postand why they make sense for single page applications SPAs.

Single page apps make a lot of sense for customer-centric applications that handle a lot of user data. But it poses an authentication problem: how do you open up your API access in a secure way?

Most websites use a strategy that stores a cookie in the browser. After you login this cookie contains an ID that links you to a session maintained somewhere in the server. This session knows who you are when you make a request using that cookie. There is nothing wrong with this practice as long as you use HTTPS only cookies that cannot be read by Javascript or non-secure transports. You should also implement a CSRF mitigation strategy.

This is a Base64 encoded string. What you see is a header which describes the token, a payload which contains the juicy bits, and a signature hash that can be used to verify the integrity of the token if you have the secret key that was used to sign it. This is the payload of your token, technically called the JWS Payload. It allows you to know the following:.

This provides some interesting optimizations for your backend architecture, but there are some tradeoffs and we discuss them in a later section. Tokens are given to your users after they present some hard credentials, typically a username and password but they could also provide API keys or even tokens from another service. The idea is that you present your hard credentials once and then you get a token that you use in place of the hard credentials.

It provides structure and security, but with the flexibility to modify it for your application. SPAs tend to have many faces: the logged in view, the logged out view, or the restricted view. Your users are all getting the same app but they may not have the same levels of access.

Because tokens contain all this information, they are very portable: they can be used by your UI and your backend to make decisions.

You can share them with partner services as a means of building Single Sign On services that delegate users to the correct application.C ASP. NET has a setting in the web. The default timeout value usually hovers around 20 minutes for ASP. While this is the expected behavior, often clients may require the session timeout to be increased dramatically or even avoid any timeout at all while the user is logged in.

single page application session timeout

This article describes a solution for web applications which require a session to never timeout or for those who have a session timeout occurring before the value set in the web. The solution is invisible and seamless and has been tested in Internet Explorer, Firefox, and Safari.

A typical scenerio where a user may want to remain permanently logged in until specifically logging out could include a phone technical support operator. The operator logs into a web application to begin taking calls and modifying data. A phone call could last over an hour, with the operator modifying data in between on a single page, and a session timeout at this point could result in a loss of data for the operator.

To resolve this, the client may specify to increase the session timeout to several hours. Certainly, the operator would finish a call within a few hours before a page refresh. If sliding expiration is enabled which it is by default in Visual Studiothe moment a postback occurs within your C ASP. NET web application, the session timeout counter is refreshed.

This means that as long as the user is navigating pages or utilizing controls which issue a postback, the session will remain active.

The session timeout problem occurs, such as in the example above, when a user remains on a single page for too long, such as a data-entry page, before clicking the save button. At first glance, increasing the session timeout value in C ASP. You would assume that by changing the timeout value to 60 minutes in the line below, that a user would remain logged into a web application session for a full 60 minutes. However, there are actually two problems with this. The first problem is that setting the timeout value to anything greater than 1 hour will result in excessive memory being held on the server, as IIS holds all session memory for the duration of the session.

Imagine a timeout value of 5 hours on a high traffic site, holding all session data for thousands of user sessions. The second problem may come upon testing the application, where often the web application will timeout after only 15 minutes. What exactly is happening? While the problem may actually be a value configured in IIS for the session timeout or connection timeout properties which in the case of shared hosting, you may not even have access toit becomes apparent we need to take control of the session timeout into our own hands.

Offhand, the most obvious solution would be to ask the user to refresh their web browser at least every 15 minutes if they plan to remain on a single page that long. This is a poor solution for obvious reasons.
