==The project in a nutshell==
  
−
The OWASP Top 10 Privacy Risks Project aims to develop a top 10 list for privacy risks in web applications because currently there is no such catalog available. The list will cover technological and organizational aspects like missing data encryption or the lack of transparency.
+
The OWASP Top 10 Privacy Risks Project provides a top 10 list for privacy risks in web applications and related countermeasures. It covers technological and organizational aspects that focus on real-life risks, not just legal issues. The Project provides tips on how to implement privacy by design in web applications with the aim of helping developers and web application providers to better understand and improve privacy. The list uses the OECD Privacy Guidelines as a framework and can also be used to assess privacy risks associated with specific web applications.

==Introduction==
+
Part 2:
  
−
Discussions about how to protect privacy and personal data are ongoing and mostly pushed by lawyers and legal experts. But there is no specific description of privacy risks for web applications that companies can apply during development and for users to check whether their privacy is protected well. There are helpful concepts like Privacy by Design, but no detailed description of real life risks causing incidents and privacy breaches in practice. This project will mitigate this gap and create a Top 10 list with technical and organizational privacy risks in web applications and possible counter-measures. Beyond that, we want to raise the awareness of the management and people who are involved in creating and operating web applications for privacy risks during the SDLC and the usage of the data, bring visibility to the right issues and create a community of people that gives practical input for further developement of this project.

; Why is this project only about web applications and not about any kind of software?
+
==Frequently Asked Questions==
−
: Web applications can easily collect data from users without their permission or informing them about the usage of their data. Trackers and cookies deliberately enable the monitoring of the users behaviour, often for selling those data. That is the reason why this subject is so important, especialy for web applications.

 +
===Why is this project only about web applications and not about any kind of software?===
 +
Web applications can easily collect data from users without their permission or without adequately informing them how their data is used. Cookies, and other trackers, enable the monitoring of user's behaviour, and this information may be used for a variety of commercial purposes, including targeted advertising, profiling, and the sale of aggregated data. This is why the subject is so important, especially for web applications.
 +
 
 +
===Are the Top 10 Privacy Risks applicable for mobile apps as well?===
 +
Privacy risks for mobile apps are very similar. The rating might be slightly different and there might be some additional risks related to the loss of devices and the use of location data, but in general the Top 10 Privacy Risks are applicable for mobile apps as well.

===What is the difference between this project and the OWASP Top 10?===
−
: There are two main differences. First, the OWASP top 10 describes technical risks, that are not primarily affecting privacy. Second, the OWASP top 10 does neither regard intended parts of the software like cookies or trackers nor organisational issues like privacy agreements or profiling.

The project in a nutshell

The OWASP Top 10 Privacy Risks Project provides a top 10 list for privacy risks in web applications and related countermeasures. It covers technological and organizational aspects that focus on real-life risks, not just legal issues. The Project provides tips on how to implement privacy by design in web applications with the aim of helping developers and web application providers to better understand and improve privacy. The list uses the OECD Privacy Guidelines as a framework and can also be used to assess privacy risks associated with specific web applications.

Top 10 Privacy Risks

P1    Web Application Vulnerabilities
P2    Operator-sided Data Leakage
P3    Insufficient Data Breach Response
P4    Insufficient Deletion of personal data
P5    Non-transparent Policies, Terms and Conditions
P6    Collection of data not required for the primary purpose
P7    Sharing of data with third party
P8    Outdated personal data
P9    Missing or Insufficient Session Expiration
P10  Insecure Data Transfer

Further information is provided in the Top 10 Privacy Risks tab.

Top 10 Privacy Risks 2014

Version 1.0 of the OWASP Top 10 Privacy Risks list. Further information and related countermeasures are provided in this PDF document.

No. Title Frequency Impact     Description
P1 Web Application Vulnerabilities High Very high Vulnerability is a key problem in any system that guards or operates on sensitive user data. Failure to suitably design and implement an application, detect a problem or promptly apply a fix (patch) is likely to result in a privacy breach. This risk also encompasses the OWASP Top 10 List of web application vulnerabilities and the risks resulting from them.
P2 Operator-sided Data Leakage High Very high Failure to prevent the leakage of any information containing or related to user data, or the data itself, to any unauthorized party resulting in loss of data confidentiality. Introduced either due to intentional malicious breach or unintentional mistake e.g. caused by insufficient access management controls, insecure storage, duplication of data or a lack of awareness.
P3 Insufficient Data Breach Response High Very high Not informing the affected persons (data subjects) about a possible breach or data leak, resulting either from intentional or unintentional events; failure to remedy the situation by fixing the cause; not attempting to limit the leaks.
P4 Insufficient Deletion of Personal Data Very high High Failure to effectively and/or timely delete personal data after termination of the specified purpose or upon request.
P5 Non-transparent Policies, Terms and Conditions Very high High Not providing sufficient information to describing how data is processed, such as its collection, storage, and processing. Failure to make this information easily-accessible and understandable for non-lawyers.
P6 Collection of data not required for the primary purpose Very high High Collecting descriptive, demographic or any other user-related data that are not needed for the purposes of the system. Applies also to data for which the user did not provide consent.
P7 Sharing of Data with Third Party High High Providing user data to any third-party, without obtaining the user’s consent. Sharing results either due to transfer or exchanging for a monetary compensation or otherwise due to inappropriate use of third-party resources included in the web site like widgets (e.g. maps, social networks buttons), analytics or web bugs (e.g. beacons).
P8 Outdated personal data High Very high The use of outdated, incorrect or bogus user data. Failure to update or correct the data.
P9 Missing or insufficient Session Expiration Medium Very high Failure to effectively enforce session termination. May result in collection of additional user-data without the user’s consent or awareness.
P10 Insecure Data Transfer Medium Very high Failure to provide data transfers over encrypted and secured channels, excluding the possibility of data leakage. Failure of enforcing mechanisms limiting the leak surface, e.g. allowing to infer any user data out of the mechanics of Web application operation.

Note: The values between 0 to 3 used for frequency and impact rating were replaced by a textual description: 0-1: Low, 1-1.5: Medium, 1.5-2: High, > 2: Very high

Frequently Asked Questions

Why is this project only about web applications and not about any kind of software?

Web applications can easily collect data from users without their permission or without adequately informing them how their data is used. Cookies, and other trackers, enable the monitoring of user's behaviour, and this information may be used for a variety of commercial purposes, including targeted advertising, profiling, and the sale of aggregated data. This is why the subject is so important, especially for web applications.

Are the Top 10 Privacy Risks applicable for mobile apps as well?

Privacy risks for mobile apps are very similar. The rating might be slightly different and there might be some additional risks related to the loss of devices and the use of location data, but in general the Top 10 Privacy Risks are applicable for mobile apps as well.

What is the difference between this project and the OWASP Top 10?

There are two main differences. First, the OWASP Top 10 describes technical risks, that are not primarily affecting privacy. Second, the OWASP Top 10 do not address software such as cookies or trackers, or organisational issues like privacy notices, profiling, or the sharing of data with third parties.

Why should companies and other organisations be concerned about privacy risks?

Privacy risks may have serious consequences for an organisation, such as:

  • perceived harm to privacy;
  • a failure to meet public expectations on both the use and protection of personal information;
  • retrospective imposition of regulatory conditions;
  • low adoption rates or poor participation in the scheme from both the public and partner organisations;
  • the costs of redesigning the system or retro-fitting solutions;
  • failure of a project or completed system;
  • withdrawal of support from key supporting organisations due to perceived privacy harms; and/ or
  • failure to comply with the law, leading to enforcement action from the regulator or compensation claims from individuals.
