DESCRIPTIONToday’s software applications are often security-critical, making security testing an essential part of a software quality program. Unfortunately, most testers have not been taught how to effectively test the security of the software applications they validate. Join Jeff Payne as he shares what you need to know to integrate effective security testing into your everyday software testing activities. Learn how software vulnerabilities are introduced into code and exploited by hackers. Discover how to define and validate security requirements. Explore effective test techniques for assuring that common security features are tested. Learn about the most common security vulnerabilities and how to identify key security risks within applications and use testing to mitigate them. Understand how to security test applications—both web- and GUI-based—during the software development process. Review examples of how common security testing tools work and assist the security testing process. Take home valuable tools and techniques for effectively testing the security of your applications going forward.

Copyright 2011 Coveros, Inc.. All rights reserved.7What is Information Security? Definition of Information Security Information Security means protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, perusal, inspection, recording or destruction. The key concepts of Information Security include: Confidentiality Integrity Availability Authenticity Non-Repudiation Copyright 2011 Coveros, Inc..

All rights reserved.9Understanding Risk How to Define Security Risk in Software Common Security Nomenclature Risk: a possible future event which, if it occurs, will lead to an undesirable outcome Threat: A potential cause of an undesirable outcome Vulnerability: Any weakness, administrative process, or act of physical exposure that makes an information asset susceptible to exploit by a threat. An exploit is a piece of software, a chunk of data, or sequence of commands that takes advantage of a vulnerability in order to cause unintended or unanticipated behavior to occur on computer software, hardware, or something electronic.

Security Testing is testing used to determine whether an information system protects its data from its threats. Security Testing is not a silver bullet for your enterprise security. Security Testing doesnt fix your security, it only makes you aware of it. Security must be built into your software A sound Security Testing process performs testing activities: Before development begins During requirements definition and software design During implementation During deployment During maintenance and operations Copyright 2011 Coveros, Inc..

Always remember that security testing evaluates the security posture of your applications, it does not build security in. Irrespective of your findings, do not become the quality police.

Defines development activities that builds security in Defines security testing activities performed by appropriate parties (development, testing, security org, operations, etc.)Common secure software development models Microsofts Secure Development Lifecycle (SDL) Coveros SecureAgile process There are others as wellSecure software standards Secure coding standard Copyright 2011 Coveros, Inc..

All rights reserved.168 11. 9/5/2012Security testing during definition and design What is a Security Requirement? Security Requirements describe functional and nonfunctional requirements that need to be satisfied in order to achieve the security attributes of an IT system or application.What does that mean? Security Requirements are formulated at different levels of abstraction and provide how the system should act, and what should not happen. The major difference you may notice is the use of negative requirements. We stop thinking about what the application should do and start thinking about how we can get it to do something it was never intended to. Copyright 2011 Coveros, Inc.. All rights reserved.17Functional Requirements Your Standard Definition Functional Requirements: These are statements of services the system should provide, how the system should react to particular inputs and how the system should behave in particular situations. In some cases, the functional requirements may also have explicitly state what the system should not do.Where does the Security fit in? Each Functional Security Requirement utilizes uses case and misuse cases. These requirements reflect potential threats to the system. Copyright 2011 Coveros, Inc..

Each team will identify potential misuse cases with the following security requirement, if any exist. If a misuse case is identified, write a replacement or additional functional requirement(s). It would be best to make sure no misuse cases can be derived from your new requirement(s).Exercise Time Limit: 15 Minutes Copyright 2011 Coveros, Inc..

The system must alert the user that their attempt to authenticate has failed due to an incorrect password (Invalid Password) utilizing the standard error text formatting. When a user attempts to authenticate with a invalid username, the application shall not authenticate the user and return them to the authentication page. The system must alert the user that their attempt to authenticate has failed due to an incorrect username (Invalid Username) utilizing the standard error text formatting. What a user attempts to authenticate using a username and a valid password, the application shall authenticate the user and redirect them to the homepage. Copyright 2011 Coveros, Inc..
