What is security testing and why it is so important?
Security Testing is described as a type of Software Testing that assures software systems and applications are free from any vulnerabilities, threats, risks that may cause a big loss. Security testing of any system is about uncovering all likely loopholes and weaknesses of the system which might end up in a loss of information, revenue, repute at the hands of the employees or outsiders of the Organization.

Review of behavior malware analysis for android
This document summarizes a review of behavior-based malware analysis for Android. It discusses existing stochastic epidemic models for malware detection that are complex. The proposed system abstracts program behaviors and compares them to reference malware behaviors to detect suspicious activities. It analyzes apps, represents them as trace languages abstracted according to behavior patterns, and detects malware by comparing to a malware database. The system gets installed apps, running tasks, extracts permission information, and detects malware to help users identify potentially malicious apps.
Security testing of mobile applications
The document provides an overview of security testing techniques for mobile applications on various platforms including Android, BlackBerry, and iOS. It discusses topics such as application threat models, traffic analysis and manipulation, insecure data storage, reverse engineering application binaries, analyzing application components and runtime behavior. The goal is to identify vulnerabilities that could impact the confidentiality, integrity or availability of the mobile application or user data.
Attribute-based Permission Model for Android Smartphones
The dependence of users on smartphones to accomplish their daily works is growing increasingly. Every day many mobile applications are downloaded and installed by the users to perform different desirable tasks for them. Before it can be installed in the smartphone, the mobile application requests from the user granting some sort of permissions, which may include the access right to users’ sensitive resources. In absence of a security mechanism that can enforce fine-grained permission control, the application may abuse the granted permissions and thus violates the security of sensitive resources. This paper proposes an attribute-based permission model ABP for Android smartphones to control how the mobile application can exercise the granted permissions. The finer granularity of the permission language used by ABP model ensures that the mobile application cannot violate the user’s security. By using ABP model, the users can enjoy the useful tasks the mobile applications provide while protecting sensitive resources from unauthorized use.

Webinar: Designing a schema for a Data Warehouse
Are you new to data warehouses (DWH)? Do you need to check whether your data warehouse follows the best practices for a good design? In both cases, this webinar is for you.
A data warehouse is a central relational database that contains all measurements about a business or an organisation. This data comes from a variety of heterogeneous data sources, which includes databases of any type that back the applications used by the company, data files exported by some applications, or APIs provided by internal or external services.
But designing a data warehouse correctly is a hard task, which requires gathering information about the business processes that need to be analysed in the first place. These processes must be translated into so-called star schemas, which means, denormalised databases where each table represents a dimension or facts.
We will discuss these topics:
- How to gather information about a business;
- Understanding dictionaries and how to identify business entities;
- Dimensions and facts;
- Setting a table granularity;
- Types of facts;
- Types of dimensions;
- Snowflakes and how to avoid them;
- Expanding existing dimensions and facts.

Android application security unveiled
- 1. Android application security unveiled Jan Hodermarsky
- 2. About me?
- 3. The main idea behind this talk? Every and each single application installed on an Android device presents a potential security risk for the user. -Unless it’s bug-free -Nothing ever developed by mankind is bug-free
- 4. Agenda -Android security principles -Intents -Where the vulnerabilities at? -Real-time exploitation of Odnoklassniki (ok.ru)
- 5. Security model - Linux-based -Linux-style permission system -Each process has its own VM. -Every app runs in its own Linux process.
- 6. Apart from classical Linux security? Android’s own security principles -No application, by default, has permission to perform any operations that would adversely impact other applications, the operating system, or the user. -Additional finer-grained security features are provided through a "permission" mechanism
- 7. Permissions -Allow apps to access resources -Requested statically in AndroidManifest.xml -No support for dynamically granting apps permissions at run-time.
- 8. Permission protection level -Normal -Dangerous -Signature -Signature or System Can be acquired by any application
- 10. -Typed messages sent between components -Used for inter and intra application communication Inter component communication Intent
- 11. -target component is specified by a fully-qualified class name -usually for calling components contained within your application Explicit intents
- 12. -Destination is left up to device to decide where it will go Implicit intents
- 13. -Can be made public or private -Can be protected by permissions Component protection
- 14. -Overprivileged application -Intent spoofing -Unauthorized intent receipt -Privilege redelegation -Query string injection -Sticky broadcasts -Insecure storage -Insecure communication -Lack of native responsibility Where the vulns at?
- 15. Overprivileged applications -Overprivileged applications -applications that request more permissions that they actually need -Why is it risky? -Any vulnerability may give the attacker that privilege -Users get accustomed to accepting applications requiring unnecessary privileges -> Malware
- 16. Overprivileged applications Badoo android application requires SEND_SMS, RECEIVE_SMS and INTERNET permission Isn’t is suspicious? Would you entrust your privacy to Badoo?
- 17. Overprivileged applications Why does it happen? -General understanding of android principles lacks -Confusing permission names -Testing purposes -Related methods - setters/getters
- 18. Overprivileged applications General danger Security aware users might refuse to install your application
- 19. -When component is public and requires no special permission Aftermath? -A malicious app sends an intent to a legitimate component, resulting in data injection or state change Intent Spoofing
- 20. 1.Mitigation -Explicitly set the value of android:exported -Make use of permissions. -If you write a component that you would like to be accessible only to another application you’ve written Intent Spoofing
- 21. Unauthorized Intent Receipt -Arises when the intent is sent implicitly and does not require the receiving component to have any special permission -Malicious app intercepts an intent Aftermath? -May lead to privacy sensitive information leaks Intent i = new Intent(); i.setAction(“my.special.action”); [startActivity|sendBroadcast|startService](i);
- 22. Unauthorized Intent Receipt Mitigation -Do not use implicit intents for communication between the components of a single app. Intent m = new Intent(); m.setClassName("hoder.john.android", "hoder.john.android.ui.activity.TestActivity"); startActivity(m); -Or require the target application to have a permission Intent n = new Intent(); n.setAction(“my.special.action”); sendBroadcast(n, “my.special.permission”);
- 23. Privilege redelegation -Malware does not have permission to do an action which requires a privilege, still it achieves to do it -Legitimate application has permission. -Legitimate application exposes its component without verification -Malware utilizes the permission of legitimate application to complete the malicious behavior. -avoids AV detection, static analysis tools detection
- 24. -Users are often not aware of any danger -more complex security principles than desktop -Sensitive data stored on Smartphones -“Always-On” makes it a great target for malware Why would we exploit android apps?
- 26. That's all folks Thank you for your attention!
