The Cloud and Mobility revolution, intensified by the quickly evolving threat landscape, heightens the
challenge for businesses to secure their IT infrastructure. Now they must fight security threats that target
their employees, applications, and other assets - not just on-premises, but throughout all of cyberspace.
The document discusses four main problems with the traditional approach to application security:
1. Security testing creates an asymmetric arms race between testers and attackers. Traditional end-of-cycle penetration tests only provide minimal security.
2. Applications often incorporate outsourced, open source, or third party code that may contain vulnerabilities. Dependency issues are rarely tested.
3. It is difficult to manage vulnerabilities at scale across a large number of applications and reports from different testers.
4. Security issues overwhelm developers with too much information, creating "white noise" and prioritizing compliance over risk. Contextualizing risk is important.

The document discusses bypassing web application firewalls (WAFs). It provides 3 key points:
1) WAFs can be bypassed through obfuscation techniques like modified syntax, encodings, and Javascript obfuscation. Typical attacks blocked by WAFs can be modified to evade detection.
2) WAF rules are often closely guarded secrets, but open-source WAFs have publicly available rules allowing better scrutiny. However, all WAFs can potentially be bypassed.
3) Bypassing a WAF typically involves finding allowed characters, making an obfuscated payload, and iteratively modifying it until evasion is achieved. The document provides examples of generating strings and characters in
The document discusses the Metasploit framework, an open-source platform for developing and using exploit code. It summarizes the history and components of Metasploit, how to use exploits and payloads, and how additional tools like Meterpreter allow full control of compromised systems. Advanced techniques are covered like reflective DLL injection, maintaining persistent access, and exploiting client-side vulnerabilities.
This document describes vulnerabilities in public transport systems that use SMS tickets. It notes that the biggest public transport companies in several countries still use systems that are vulnerable to hacking SMS tickets. The vulnerabilities allow an attacker to generate and distribute valid SMS tickets to many users without them actually purchasing tickets. The document outlines several potential fixes that transport companies could implement, but also describes ways an attacker could workaround each fix, such as regenerating tickets after inspection or routing calls and SMS through a central server.
This document provides an overview of SELinux including its history and development. It was originally created by the NSA as a way to implement mandatory access controls on Linux systems. Key points discussed include how SELinux implements the Flask architecture and uses security contexts, domains, and a policy language to enforce access controls at a more granular level than traditional Linux permissions. The document also covers SELinux file system labeling and different object classes.
This document summarizes common web application attacks. It describes how attackers achieve anonymity using TOR or compromised servers. It also explains how attackers look for SQL and XSS injections using tools or obfuscated payloads to evade WAFs. The goal is often extracting sensitive data, credentials, or hashes to crack for admin access and escalating privileges to the system level. Finally, attackers will clean logs and backdoor systems to maintain access.
This document outlines an agenda for a presentation on web application attacks. The presentation will demonstrate common vulnerabilities like unvalidated parameters, access control flaws, session management issues, cross-site scripting, injection flaws, improper error handling, AJAX security issues, authentication flaws, code quality issues, concurrency problems, and parameter tampering.

How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

6. Penetration test phases
Discovery information about the target system is identified
and documented (WHOIS service, public search engines,
domain registrators, etc.)
Enumeration using intrusive methods and techniques to gain
more information about the target system (port scanning,
fingerprinting)
Vulnerability mapping mapping the findings from the
enumeration to known and potential vulnerabilities
Exploitation attempting to gain access through vulnerabilities
identified in the vulnerabilitymapping phase. The goal is to gain
userlevel and privileged (administrator) access to the system
(custom exploit scripts or exploit frameworks are used)
