Microsoft Fakes help you isolate the code you are testing by replacing other parts of the application with substitute code. These substitutes are called stubs and shims and are under the control of your tests. Microsoft Fakes is ideal when you need to test legacy or “legacy” code that is either restricted for refactoring or “refactoring” practically means rewriting and cost you a lot.

Application Security Vulnerabilities: OWASP Top 10 -2007Vaibhav Gupta
General concepts of web application security vulnerabilities primarily based on OWASP Top 10 list-2007(I know its too old :-))
I, along with Sandeep and Vishal, presented on this at IIIT-Delhi college in April, 2014
International Journal of Engineering Research and Applications (IJERA) is an open access online peer reviewed international journal that publishes research and review articles in the fields of Computer Science, Neural Networks, Electrical Engineering, Software Engineering, Information Technology, Mechanical Engineering, Chemical Engineering, Plastic Engineering, Food Technology, Textile Engineering, Nano Technology & science, Power Electronics, Electronics & Communication Engineering, Computational mathematics, Image processing, Civil Engineering, Structural Engineering, Environmental Engineering, VLSI Testing & Low Power VLSI Design etc.
Web Security has been a major concern today. Battles have long raged over how others can access and use your data.Year on year, online privacy faces new threats , as a result of emerging technologies and new regulatory efforts that could affect how your web based life is protected or exposed. Let's get insight into these secure vulnerabilities and how we can define strategy around security testing with this VodQA.We will be using OWASP ZAP (short for Zed Attack Proxy) is an open source web application security scanner. It is intended to be used by both those new to application security as well as professional penetration testers.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

5. Agenda
Importance of Web Security
HTTP, Sessions, Cookies
Injection
Cross Site Scripting (XSS)
Cross-Site Request Forgery (CSRF)
Security Misconfiguration
Insecure Direct Object References
6. Famous Quote
“Every program has at least two purposes: the
one for which it was written, and another for
which it wasn't.”
-Alan J. Perlis
Alan Jay Perlis was an computer scientist known for his
pioneering work in programming languages, and is the first
recipient of the Turing Award.

string query="INSERT INTO Students VALUES ('"+txtName.Text+"','"+txtSSN.Text+"')";
//Attack: Robert’); DROP TABLE Students;-INSERT INTO Students VALUES ('Robert'); DROP TABLE Students;-Students;--','12345')
Robert');
10. HTTP
Hypertext Transport Protocol
– Language of the Web. Protocol used for
communication between web browsers and web
servers
– Standard RFC 1945, 1996
URL
– Uniform Resource Identifier
Methods
– GET, POST, PUT, HEAD, OPTIONS
11. Statelessness, Cookies
In its nature HTTP it is said to be a stateless protocol.
– i.e. from one web page to the next there is nothing in the
protocol that allows a web program to maintain program “state”
(like a desktop program).
– “state” can be maintained by “witchery” or “trickery” if it is
needed.
Cookie – piece of data sent from a website and stored in a
user's web browser while a user is browsing a website.
– The Server sets the cookie in a response.
– The client includes the cookies in the Http header for
subsequent requests to the server.
– Example Cookie:
ASP.NET_SessionId=haay355s5g0vm5zotvlncqpr
14. Injection
OWASP Definition
– Injection flaws, such as SQL, OS, and LDAP
injection, occur when untrusted data is sent to an
interpreter as part of a command or query. The
attacker’s hostile data can trick the interpreter
into executing unintended commands or accessing
unauthorized data.
17. SQL Queries
Queries constructed with concatenating
strings are vulnerable to SQL Injection.
var categoryId = Request.QueryString["CategoryId"];
var sql =
"SELECT * FROM Products WHERE CategoryID=" + categoryId;
// If we enter "7 OR 1=1" in query string we end up with:
SELECT * FROM Products WHERE CategoryID=7 OR 1=1
// Attacker can use ; to terminate current command and run its
own commands.
SELECT * FROM Products WHERE CategoryID=7; DROP TABLE Products
18. Prevent SQL Injection
Validate untrusted data. If input data is supposed
to be number, convert it to number or check it
with regex.
Use parameterized SQL queries instead of strings
soup.
– Using stored procedures is also a good idea but keep
in mind that stored procedures are vulnerable if they
concatenate strings on their own.
Use ORMs (like Entity Framework) that are
inherently resistant to SQL Injection.
20. Cross-Site Scripting (XSS)
OWASP Definition
– XSS flaws occur whenever an application takes
untrusted data and sends it to a web browser
without proper validation and escaping. XSS
allows attackers to execute scripts in the victim’s
browser which can hijack user sessions, deface
web sites, or redirect the user to malicious sites.
22. Types of XSS Attacks
Stored XSS
• Stored attacks are those where the injected code is
permanently stored on the target servers.
• Users should not be able to create message content that
could cause another user to load an undesirable page or
undesirable content when the user's message is retrieved.
Reflected XSS
• Reflected attacks are those where the injected code is
reflected off the web server, such as in an error
message, search result.
• Reflected attacks are delivered to victims via another
route, such as in an e-mail message, or on some other web
server.
23. Built-in protection
Modern browsers and servers employ many
first line defenses against XSS by default:
– ASP.NET Request Validation, present since version
2.0. In ASP.NET 4.0 it is enabled for all types of
requests not just pages. To be turned off we must
revert to the older mode
requestValidationMode="2.0“
– Output encoding. MVC Razor view engine encodes
everything by default. XSS is possible only if we
use @Html.Raw()
24. Built-in protection
– AntiXSS library is by default included in ASP.NET
Web Forms 4.5. Can be retrofitted on older web
apps.
– Google Chrome has built-in anti XSS protection
25. Cross-Site Request Forgery
OWASP Definition
– A CSRF attack forces a logged-on victim’s browser
to send a forged HTTP request, including the
victim’s session cookie and any other
automatically included authentication
information, to a vulnerable web application. This
allows the attacker to force the victim’s browser to
generate requests the vulnerable application
thinks are legitimate requests from the victim.
27. How CSRF works
Authenticated sessions are persisted via cookies The
cookie is sent with every request to the domain
The attacking site recreates a legitimately formed request
to the target site Although the request has a malicious
payload (query string parameters or post data)
The victim’s browser is tricked into issuing the request
For all intents and purposes, the target website views it
as a legitimate request
28. CSRF Tokens
To mitigate this risk, we can add randomness via a CSRF
token
A token is a random string known to both the legitimate
page where the form is and to the browser via a cookie
29. Security Misconfiguration
OWASP Definition
– Good security requires having a secure
configuration defined and deployed for the
application, frameworks, application server, web
server, database server, and platform. All these
settings should be defined, implemented, and
maintained as many are not shipped with secure
defaults. This includes keeping all software up to
date, including all code libraries used by the
application.
31. Keep up to date
Your servers
– Windows Server 2012 is arguably more secure
than Windows Server 2003
Client browsers (if applicable)
– Modern browsers include built-in defenses against
most prevalent attacks
Keep your frameworks up to date
34. Also don’t forget to turn off
ELMAH
– Cases with unprotected ELMAH handlers are
notorious.
– Googledork: inurl:”elmah.axd”
DEBUG
– Performance penalties
– Although not related with direct security risks on
its own beware of #if DEBUG statements that
can disclose information
35. Also don’t forget to turn off
Script execution on folders where not needed
– Usually folders where various documents or
uploaded files are kept, unless you use App_Data
folder.
HTTP Access to Logs
– Log files can disclose many sensitive details about
your web app. It’s best to keep them outside of
the web app root. If not possible at least keep
them in App_Data.
36. Insecure Direct Object References
OWASP Definition
– A direct object reference occurs when a developer
exposes a reference to an internal implementation
object, such as a file, directory, or database key.
Without an access control check or other
protection, attackers can manipulate these
references to access unauthorized data.
38. Direct Object References
– A direct object reference is an observable key
used to identify an individual record in database
• http://northwind.com/Products?catId=1
• http://northwind.com/Products?catId=3
• http://northwind.com/Products?catId=8
39. Direct Object References
– Another example
• http://webapp.com/Download?f=DSC01031.JPG
• http://webapp.com/Download?f=DSC01032.JPG
• http://webapp.com/Download?f=DSC01033.JPG
40. Prevention
Implementing proper access control
– Validate user data
– Implement security checks before using object
reference
Access via undiscoverable surrogate keys
– Integer and natural string types are vulnerable to
enumeration
– A surrogate key that is not pattern-based can add
further obfuscation
• A GUID is a good example
– However, it is security through obscurity
41. Real example: phishing with
obfuscated SQL injection and XSS
--1. The malicious query appends script to all text values in all tables in the database
DECLARE @T varchar(255),@C varchar(4000)
DECLARE Table_Cursor CURSOR FOR
select a.name,b.name from sysobjects a,syscolumns b

FETCH NEXT FROM Table_Cursor INTO @T,@C
END
CLOSE Table_Cursor

42. Real example : phishing with
obfuscated SQL injection and XSS
--2. The query is wrtten as one line string
'DECLARE @T varchar(255),@C varchar(4000) DECLARE Table_Cursor CURSOR FOR select a.name,b.name from sysobjects a,syscolumns b where a.id=b.id and a.xtype=''u'' and (b.xtype=99 or

--3. We cast the query string as varbinary to obfuscate the XSS attack and to bypass XSS filters.
SELECT CAST('DECLARE @T varchar(255),@C varchar(4000) DECLARE Table_Cursor CURSOR FOR select a.name,b.name from sysobjects a,syscolumns b where a.id=b.id and a.xtype=''u'' and

Editor's Notes
A big part of web application security testing involves attempts to force an application to function in a way it was not intended to.Alan Jay Perlis was an computer scientist known for his pioneering work in programming languages and the first recipient of the Turing Award (Nobel prize of computing)
Code: string query = "INSERT INTO Students VALUES ('" + txtStudentName.Text + "‘,’” + txtSSN.Text+ ”’)";Attack: Robert’); DROP TABLE Students;--Result: INSERT INTO Students VALUES ('Robert’); DROP TABLE Students;-- ‘,’12345’)
q = "INSERT INTO Students VALUES ('" + txtStudentName.Text + "')";Robert’); DROP TABLE Students;--
Enter OWASP, the Open Web Application Security Project, a non-profit charitable organisation established with the express purpose of promoting secure web application design. OWASP was started on September 9, 2001 By Mark Curphey and Dennis Groves. Since late 2003, Jeff Williams served as the volunteer Chair of OWASP until September 2011. The current chair is Michael Coates, and vice chair is EoinKeary. The OWASP Foundation, a 501(c)(3) organization (in the USA) was established in 2004 and supports the OWASP infrastructure and projects.
