Meeting minutes October 27th 2008

At October 27th, the Dutch OWASP chapter came together at the office of the sponsor of the evening; ps_testware in Doorn. The subject of the evening was 'Privacy and the Internet’. There were 2 speakers and approximately 25 attendees.

After a short welcome talk by both the sponsor and OWASP, Mario de Boer had an announcement about a new OWASP project; ORPRO, the Open Review Project. The goal of the project is to review Open Source Software from an independent point of view. Reviews will be done both manually and with the aid of source code analysis software provided by Fortify. The first software package to be reviewed is already available so reviewers are needed. More information can be found on the OWASP project page. [1]

First presentation: Privacy & the Internet presented by Frank Fruijthoff and Ellen Hoving.
The goal of this presentation was to show the problems in regulating privacy on the internet by law. The presentation was roughly split in 3 parts: definitions, requirements and context.
The main problem with regulating privacy is that the concept of privacy is very broad and not well defined. Privacy can have different meanings and consequences in different contexts. Most laws therefore focus on the individual and define privacy as 'protection of personal information' where 'personal information' is all data that can be tracked back to a single person. The last years many countries within the EU developed internet laws concerning privacy on the internet. These laws state that information can only be used what it originally was intended for and usage of that information must be reported at central register. This register also makes it possible to file a complaint and check what companies use personal information for what purposes. While these rules are mostly sufficient for local databases they often fail when applied to information stored on or with use of the internet. Problems encountered are captured in the "four D's";
- Internet is deterritorialized; internet has no boundaries.
- Internet is deregulated; internet has no law, only terms of use.
- Internet is dematerialized; internet is not physical.
- Internet is decentralized; there is no single regulating or controlling organization.
Although the protection of personal data is more and more covered by laws, the increasing usage of external storage and connections over the internet will make it harder to enforce them. The main conclusion of the evening was that, although many initiatives improving privacy exist, the very properties of the internet make it hard to ensure privacy completely.

Second presentation: Vulnerability and source code scanners presented by E. Strijbos. This presentation showed the results of a research concerning the feasibility of a Web Application Security Certification by the usage of vulnerability scanners.
With the daily increasing amount of threads and vulnerabilities in web applications there is a market-driven demand for an independent and automated scan service. Current scan services often lack coverage and depth of scanning and give no details about the used scanning methods.
In this research several commercial vulnerability scanners and static analysis tools were compared and checked for scantime, accuracy, false positives, and ease of use. The results showed that almost all scanners find most of the vulnerabilities, but also produce many false positives. Also, without proper configuration the amount of results can be overwhelming and inconclusive. Furthermore results showed that static analysis scanners are much faster than vulnerability scanners, but have a more limited usage. The main conclusion was that although vulnerability scanners and static analysis tools can be very helpful in identifying vulnerabilities, their current efficiency is not high enough to use as the basis for an automated vulnerability scan.

Meeting October 27th 2008: Privacy and the Internet

Summary
The main goal of the upcoming OWASP-NL meeting is to provide information to developers and security professionals about personal and technical privacy on the internet. The speakers focus on privacy regulations related to the internet and on the mass amount of personal and technical information available about persons and companies on the internet, with and without their consent. Furthermore tools will be discussed that help prevent leakage of privacy related and other kind of data. They will give specific examples and there will be time to ask questions.
Please register before October 20th because of the necessary catering arrangements.

20.15 – 20:30 Break

20:30 – 21:00 Vulnerability and source code scanners (Dutch), Emile Strijbos
For his Master thesis in computer science at the Radboud Universiteit in Nijmegen, Emile Strijbos investigated vulnerability scanners and source code scanners. These are automated tools that try to detect security flaws, either in running web-applications or in their source code.
Emile tried out several of these tools, including both free and commercial ones, to see how good they are at detecting standard vulnerabilities, such as SQL injection, XSS, CSRF, etc.

Meeting minutes March 23th 2008

At March 23th, the Dutch OWASP chapter came together in the Mercury hotel in Nieuwegein. The meeting was sponsored by Fortify Software. The subject of the evening was 'Software Vulnerability Assesment’. There were 3 speakers and approximately 40 attendees.

After a short introduction of Migchiel de Jong (Fortify) about the subject of Static and Dynamic Analysis and the tools that Fortify provides the speakers of the evening where introduced.

First presentation: Practices of Complex(ity) matters (Dutch), Mario de Boer
Mario de Boer has spent much of his free time the last 16 years into disassembling various pieces of software and analyzing the code and its statistics. The main advantage in analyzing binaries is that no access to source code is needed, all dependencies (i.e. the compiler) are included and it’s independent of the tool used. Disassembling compiled code gives great insight in the complexity of the software and the entry and exit points of data. Although there is no direct relation between the complexity of software and its security, statistically the most vulnerabilities appear in the most complex portions of a program. Data entry points in complex portions of the code can give rise to possible exploits so static analysis can give insight in the most vulnerable places in software which is useful information in testing. The disadvantages of static analysis are that an extensive knowledge of assembly is needed and, due to its statistic nature, it gives rise to many false positives. In conclusion static binary analysis, when used by experts, can be a powerful tool to gain insight in the most vulnerable parts of the software and be a valuable tool in both developing and testing software.

Second presentation: V.A.C: SQL injection (Dutch), Marinus Kuivenhoven
A new reoccurring topic on OWASP presentations will be the so called VAC. In these presentations an expert will talk about a Vulnerability, how to Assess it and possible Countermeasures. This evening Marinus started with the second vulnerability in the OWASP top ten; SQL injections.
With the aid of Webgoat, a few simple examples and the possible consequences were shown. SQL injection is particularly useful exploit in the reconnaissance phase since it can be abused for information leakage and in getting information about e.g. the table structure.
On the internet and in literature many countermeasures against SQL injections are described. However, many of these countermeasures are not usable in a maintainable system or cannot prevent SQL injections completely. The most important conclusion was that input should never be trusted and should never be directly used.

Third presentation: Secure Programming with Static Analysis (English), Brian Chess
The last speaker of the evening was Brian Chess who presented his new book ‘Secure Programming with Static Analysis’. Brian made clear that, although a powerful tool, static binary analysis is already too late in the SDLC to be successful in preventing vulnerabilities. Scanning for possible vulnerabilities should be implemented as early as possible i.e. during coding. The main advantages of static analysis are the cost and speed. Since errors and bad practices are identified in an early stage they can be solved at the spot, making auditing the software more efficient in term of time and depth.
Static analysis can successfully be used for style and type checking, program understanding and verification, and for security reviews. The success of static analysis, however, is fully depending on the rules implemented in the scanner. Static analysis is also unable to identify design flaws, right problems, or wrong user input.
The conclusion was that scanning for vulnerabilities can probably only be successful with the aid of static analysis, but many requirements should be met. Firstly it should become part of the SDLC and culture. Secondly the right tool should be picked and people should be trained in its use. Lastly investments should be made in building up a good rule set and metrics.

Program
17.30 - 18.30 Check-In (catering included)

18.30 - 18:50 Introduction (OWASP, sponsor)

18.50 - 19.30 Complex(ity) matters (Dutch), Mario de Boer
Various methods exist to locate specific vulnerabilities in software. In the presentation we will look at static analysis of binaries, and the problems we face when trying to locate vulnerabilities. Several ideas will be discussed to make the search easier, but at the same time less exact. The first idea is trivial: automate as much as possible. The second idea is nearly trivial: don't aim at exact vulnerabilities but relax the search to locating potential vulnerabilities. We will give examples that illustrate the results.
Mario de Boer is a senior security consultant at Logica, and as such focuses on security management aspects like security frameworks, compliance, monitoring and control and risk management. Before joining Logica, Mario worked at the Dutch ministries of Defense and Justice, he co-founded a security company and worked as a project manager in the financial sector. For several years he taught courses in software security analysis and secure software development. Besides security management, Mario has interest in software security, reverse engineering and cryptography. Within Logica Netherlands, he is knowledge manager application security. Mario holds a PhD in Mathematics and is CISA and CISSP.

19.30 - 19:50 Break

19:50 - 20:20 V.A.C: SQL injection (Dutch), Marinus Kuivenhoven
Vulnerability:
An application which uses a database for its information needs, communicates with it trough SQL. SQL injection is an attack in which malicious code is inserted into strings that are later passed to an instance of a Database for parsing and execution.
Assessment:
SQL injection can threaten the confidentiality, availability and integrity of the data. The various types of SQL injection and their impact will be shown.
Countermeasure:
Any procedure that constructs SQL statements should be reviewed for injection vulnerabilities because a database will execute all syntactically valid queries that it receives. How this should be done will be shown for the most popular languages.
Marinus is a Technology Specialist with Sogeti Nederland B.V. specializing in service oriented architectures and secure application development. His experience includes developing and administrating Oracle-based systems.

20.20 - 21.00 Secure Programming with Static Analysis (English), Brian Chess
Creating secure code requires more than just good intentions. Programmers need to know how to make their code safe in an almost infinite number of scenarios and configurations. Static source code analysis gives users the ability to review their work with a fine tooth comb and uncover the kinds of errors that lead directly to vulnerabilities. This talk frames the software security problem and shows how static analysis is part of the solution. We will look at how static analysis works, how to integrate it into the software development processes, and how to make the most of it during security code review. Along the way we'll look at examples taken from real-world security incidents, showing how coding errors are exploited, how they could have been prevented, and how static analysis can rapidly uncover similar errors.
Brian Chess is a founder of Fortify Software and serves as Fortify's Chief Scientist, where his work focuses on practical methods for creating secure systems. His book, Secure Programming with Static Analysis, shows how static source code analysis is an indispensable tool for getting security right. Brian holds a Ph.D. in computer engineering from the University of California at Santa Cruz, where he studied the application of static analysis to the problem of finding security-relevant defects in source code. Before settling on security, Brian spent a decade in Silicon Valley working at huge companies and small startups. He has done research on a broad set of topics, ranging from integrated circuit design all the way to delivering software as a service.
