Threat ModelingReference:

Identify assets. Identify the valuable assets that your systems must protect.

Create an architecture overview. Use simple diagrams and tables to document the architecture of your application, including subsystems, trust boundaries, and data flow.

Decompose the application. Decompose the architecture of your application, including the underlying network and host infrastructure design, to create a security profile for the application.

Identify the threats. Keeping the goals of an attacker in mind, and with knowledge of the architecture and potential vulnerabilities of your application, identify the threats that could affect the application.

Document the threats. Document each threat using a common threat template that defines a core set of attributes to capture for each threat.

Rate the threats. Rate the threats to prioritize and address the most significant threats first.

Secure Code Perspective-Code ReviewFurther Reading: Threat Modeling- Frank Swiderski, Window Snyder, A Few Billion Lines of Code Later: Using Static Analysis to Find Bugs in the Real World - doing the code review we can take the inputs from the code in the trust boundary, issues from the static tools like Fortiy, Coverity etc and put the focus at the right place for the Code Review

Reconnaissance is a the first and the key phase of penetration testing where the information is gathered. The more time you spend collecting information on your target, the more likely you are to be successful in the later phases. There can be a checklist based approach for information gathering but it need not be constrained to the list. Information Gathering helps teams to think about the product properties upfront.So OnReconnaissance / Information Gathering

SoftwareURLDescriptionMaltego defacto standard for mining data on individuals and companies. Comes in a free community version and paid version.Nessus vulnerabilty scanning tool available in paid and free versions. Nessus is useful for finding and documenting vulnerabilities mostly from the inside of a given network.IBM AppScan's automated Web application security testing suite.eEye Retina is an an automated network vulnerability scanner that can be managed from a single web-based console. It can be used in conjunction with Metasploit where if an exploit exists in Metasploit, it can be launched directly from Retina to verify that the vulnerability exists.Nexposehttp://www.rapid7.comNexpose is a vulnerability scanner from the same company that brings you Metasploit. Available in both free and paid versions that differ in levels of support and features.OpenVAShttp://www.openvas.orgOpenVAS is a vulnerability scanner that originally started as a fork of the Nessus project. The actual security scanner is accompanied with a daily updated feed of Network Vulnerability Tests (NVTs), over 20,000 in total (as of January 2011)HP WebInspect WebInspect performs web application security testing and assessment for complex web applications. Supports JavaScript, Flash, Silverlight and others.HP SWFScan SWFScan is a free tool developed by HP Web Security Research Group to automatically find security vulnerabilities in applications built on the Flash platform. Useful for decompiling flash apps and finding hard-coded credentials, etc.THC IPv6 Attack Toolkit largest single collection of tools designed to exploit vulnerabilities in the IPv6 and ICMP6 protocols.

Pen Test Tools and Guidelines-

Security Tools and Version Analysis

Tools Analysis helps the teams to select the applicable tools upfront and build required competency to use them / acquire license , well before test execution phase.

Scanning is the phase where the vulnerabilities and the weak areas in the system / target can be identified. Tools to be finalized based on the application scope.

Based on the Threat Modeling Analysis, understand the Trust Boundary.Analyze the present Risk Mitigation mechanism and derive test scenariosAnalysis the proposed Risk Mitigation mechanism and device the test scenariosThreat Modeling analysis to be done both at System and at Sub system levelSo OnSo OnSystem Scanning and further AnalysisTest Scenarios from Threat Modeling Analysis
