Top 70 Web Services Interview Questions & Answers

This page presents several best practices that have a significant, positive impact on your app's security. When you safeguard the data that you exchange between your app and other apps, or between your app and a website, you improve your app's stability and protect the data that you send and receive.

If an implicit intent can launch at least two possible apps on a user's device, explicitly show an app chooser. This interaction strategy allows users to transfer sensitive information to an app that they trust. When sharing data between two apps that you control or own, use signature-based permissions.

These permissions don't require user confirmation and instead check that the apps accessing the data are signed using the same signing key. Therefore, these permissions offer a more streamlined, secure user experience. Unless you intend to send data from your app to a different app that you don't own, you should explicitly disallow other developers' apps from accessing the ContentProvider objects that your app contains.

This setting is particularly important if your app can be installed on devices running Android 4. To learn more about how to request biometric credentials, see the guide about biometric authentication. If your app communicates with a web server that has a certificate issued by a well-known, trusted CA, the HTTPS request is very simple:. If your app uses new or custom CAs, you can declare your network's security settings in a configuration file.

This process allows you to create the configuration without modifying any app code. This element overrides your app's security-critical options during debugging and testing without affecting the app's release configuration. The following snippet shows how to define this element in your app's network security configuration XML file:.

Related info: Network Security Configuration. Your SSL checker shouldn't accept every certificate. You may need to set up a trust manager and handle all SSL warnings that occur if one of the following conditions applies to your use case:. To learn more about how to complete these steps, see the discussion about handling an unknown cerificate authority. Whenever possible, load only allowlisted content in WebView objects.

In other words, the WebView objects in your app shouldn't allow users to navigate to sites that are outside of your control. In addition, you should never enable JavaScript interface support unless you completely control and trust the content in your app's WebView objects. If your app must use JavaScript interface support on devices running Android 6.

Your app should request only the minimum number of permissions necessary to function properly. When possible, your app should relinquish some of these permissions when they're no longer needed. Whenever possible, don't add a permission to your app to complete an action that could be completed in another app.

Instead, use an intent to defer the request to a different app that already has the necessary permission. Better still, after a user selects content at a particular URI, the calling app gets granted permission to the selected resource. Follow these best practices in order to share your app's content with other apps in a more secure manner:. Apps should load only the binary code that's embedded within an app's APK file.

This includes any shared object. Related info: android:grantUriPermissions. Although your app might require access to sensitive user information, your users will grant your app access to their data only if they trust that you'll safeguard it properly.

Store all private user data within the device's internal storage, which is sandboxed per app. Your app doesn't need to request permission to view these files, and other apps cannot access the files. As an added security measure, when the user uninstalls an app, the device deletes all files that the app saved within internal storage.

Note: If the data that you're storing is particularly sensitive or private, consider working with EncryptedFile objects, which are available from the Security library , instead of File objects.

Use external storage for large, non-sensitive files that are specific to your app, as well as files that your app shares with other apps. The specific APIs that you use depend on whether your app is designed to access app-specific files or access shared files. If your app interacts with a removable external storage device, keep in mind that the user might remove the storage device while your app is trying to access it.

Include logic to verify that the storage device is available. If a file doesn't contain private or sensitive information but provides value to the user only in your app, store the file in an app-specific directory on external storage.

If your app needs to access or store a file that provides value to other apps, use one of the following APIs depending on your use case:. If your app uses data from external storage, make sure that the contents of the data haven't been corrupted or modified. Your app should also include logic to handle files that are no longer in a stable format. To provide quicker access to non-sensitive app data, store it in the device's cache. Each method provides you with the File object that contains your app's cached data.

Note: If you use getExternalCacheDir to place your app's cache within shared storage, the user might eject the media containing this storage while your app is running. You should include logic to gracefully handle the cache miss that this user behavior causes. Caution: There is no security enforced on these files. Related info: Saving cache files. That way, only your app can access the information within the shared preferences file. If you want to share data across apps, don't use SharedPreferences objects.

Instead, you should follow the necessary steps to share data securely across apps. Related info: Using Shared Preferences. Most apps use external libraries and device system information to complete specialized tasks. By keeping your app's dependencies up to date, you make these points of communication more secure.

Note: This section applies only to apps targeting devices that have Google Play services installed. If your app uses Google Play services, make sure that it's updated on the device where your app is installed. This check should be done asynchronously, off of the UI thread.

If the device isn't up-to-date, your app should trigger an authorization error. Before deploying your app, make sure that all libraries, SDKs, and other dependencies are up to date:.

The topic of this article is provided in two parts. The first part covers WS-Security features, the relationship between business participants, and the mechanics of how WS-Security capabilities are implemented. Design choices and implementations that address security requirements often have an adverse impact on a solution's performance. This is not to imply that all security technologies used in solutions result in slow performance. Rather, you should be aware that web services solutions requiring authentication of business participants, digital signature of message content, and encryption of XML data can have very different performance characteristics based on the technology or method used to secure a solution's exposed business functions and data.

Hi, i want to call java web service so i used WCF the soap header request should contain caaabbbb-cccc-dddd-eeee-ffffffffffff.

It has some specification which could be used across all applications. SOAP is a protocol or in other words is a definition of how web services talk to each other or talk to client applications that invoke them. SOAP was developed as an intermediate language so that applications built on various programming languages could talk easily to each other and avoid the extreme development effort. For example, there could be a web application designed in Java, another in.

The ILO Constitution sets forth the principle that workers must be protected from sickness, disease and injury arising from their employment. Yet for millions of workers the reality is very different. According to the most recent ILO global estimates, 2. In addition to the immense suffering caused for workers and their families, the associated economic costs are colossal for enterprises, countries and the world. The losses in terms of compensation, lost work days, interrupted production, training and reconversion, as well as health-care expenditure, represent around 3. Employers face costly early retirements, loss of skilled staff, absenteeism and high insurance premiums.

Security standards are implemented in non-XML frameworks at the transport level, and in XML frameworks at the application level. The following sections describe the standards that are key to providing secure and manageable SOA environments at both the transport and application levels. Oracle considers interoperability of Web services platforms to be more important than providing support for all possible edge cases of the Web services specifications. Oracle complies with the following specification from the Web Services Interoperability Organization and considers it to be the baseline for Web services interoperability:. Basic Security Profile 1. SSL provides the following:.

Ясно, что тот не собирался сдаваться. Скорее всего идет по его следу пешком. Беккер с трудом вел мотоцикл по крутым изломам улочки. Урчащий мотор шумным эхо отражался от стен, и он понимал, что это с головой выдает его в предутренней тишине квартала Санта-Крус. В данный момент у него только одно преимущество - скорость. Я должен поскорее выбраться отсюда.

How To Add Security Header To Soap Web Service Client On Java

Беккер взглянул на часы. Час сорок пять ночи. Он в недоумении посмотрел на двухцветного. - Ты сказал - в два ночи.

Тогда-то виновников компьютерных сбоев и стали называть вирусами. У меня нет на это времени, - сказала себе Сьюзан. На поиски вируса может уйти несколько дней. Придется проверить тысячи строк программы, чтобы обнаружить крохотную ошибку, - это все равно что найти единственную опечатку в толстенной энциклопедии.

 - У нас внизу работают лучшие программисты в мире. И мы нашими совместными усилиями даже близко не подошли к математической функции меняющегося открытого текста. А вы хотите сказать, что какой-то панк с персональным компьютером придумал, как это сделать. Стратмор заговорил тише, явно желая ее успокоить: - Я бы не назвал этого парня панком. Но Сьюзан его не слушала.

 Подними. Беккер заморгал от неожиданности. Дело принимало дурной оборот. - Ты, часом, не шутишь? - Он был едва ли не на полметра выше этого панка и тяжелее килограммов на двадцать. - С чего это ты взял, что я шучу.

Конец веревочки. Он набрал номер. - Escortes Belen, - ответил мужчина.

 Заметано. - Ну вот и хорошо. Девушка, которую я ищу, может быть. У нее красно-бело-синие волосы.

Грохнуться с этой лестницы означало до конца дней остаться калекой, а его представления о жизни на пенсии никак не увязывались с инвалидным креслом.

Немного рано для алкогольных напитков, подумал Беккер, наклоняясь. Когда серебряный кубок оказался на уровне его глаз, возникло какое-то движение, и в полированной поверхности смутно отразилась приближающаяся фигура. Беккер заметил металлический блеск в тот самый миг, когда убийца поднимал пистолет, и, как спринтер, срывающийся с места при звуке стартового выстрела, рванулся .

Разве это не услуга. Сьюзан промолчала. Она поняла: все дело в деньгах. Она перенеслась мыслями в тот вечер, когда президент Джорджтаунского университета предложил Дэвиду повышение - должность декана факультета лингвистики.

Сьюзан стояла прямо и неподвижно, как статуя. Глаза ее были полны слез. - Сьюзан. По ее щеке скатилась слеза. - Что с тобой? - в голосе Стратмора слышалась мольба.

 - Он сказал, что на кольце были выгравированы какие-то буквы. - Буквы. - Да, если верить ему - не английские.
