HOW THIS COURSE IS RUN
SECURITY PRINCIPLES AND SD3 (SECURE BY DESIGN, DEFAULT, DEPLOYMENT)
The course is designed to cover at least the OWASP top 10 and the Secure Application Development part of PCI DSS (Payment Card Industry Data Security Standard). Usually (based on delegate’s current focus) a number of other areas are covered, like for example: Unit/Integration Testing, Static Analysis tools, Penetration Testing, Code Reviews, Secure coding in Agile environments, Self-Defending applications, PHP Security, Security as a key component of Continuous Deployment/Delivery.
TECHNIQUES TO EXPLOIT VULNERABILITIES
SECURE CODING PRACTICES
TESTING AN APPLICATION FOR SECURITY
Common tools and techniques for Developers to use in their day-to-day Agile environment to help test that their applications are robust and capable of withstanding common threats
OWASP TOP 10 VULNERABILITIES
Although secure coding is a large part of the course, there will be the opportunity to learn and write exploits around multiple OWASP Top 10 vulnerabilities (like XSS, CSRF, SQL Injection or Indirect Object Reference).
The workshop will simulate a real-world Threat Modeling session, with (ideally) the target being a application currently maintained by some (or all) of the attending delegates.
A very common outcome is that new high-risk vulnerabilities are discovered during the course (the backup plan is to use vulnerable-by-design demo applications, but the learning impact is not the same as when the delegates see real-world vulnerabilities in their applications).
OWASP TOP 10 – 2017 (NEW)
A1 – INJECTION
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 data without proper authorization.
A2 – BROKEN AUTHENTICATION AND SESSION MANAGEMENT
Application functions related to authentication and session management are often not implemented correctly, allowing attackers to compromise passwords, keys, or session tokens, or to exploit other implementation flaws to assume other users’ identities.
A3 – CROSS-SITE SCRIPTING (XSS)
XSS flaws occur whenever an application takes untrusted data and sends it to a web browser without proper validation or 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.
A4 – INSECURE DIRECT OBJECT REFERENCE
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.
A5 – SECURITY MISCONFIGURATION
Good security requires having a secure configuration defined and deployed for the application, frameworks, application server, web server, database server, and platform. Secure settings should be defined, implemented, and maintained, as defaults are often insecure. Additionally, software should be kept up to date.
A6 – SENSITIVE DATA EXPOSURE
Many web applications do not properly protect sensitive data, such as credit cards, tax IDs, and authentication credentials. Attackers may steal or modify such weakly protected data to conduct credit card fraud, identity theft, or other crimes. Sensitive data deserves extra protection such as encryption at rest or in transit, as well as special precautions when exchanged with the browser.
A7 – MISSING FUNCTION LEVEL ACCESS CONTROL
Most web applications verify function level access rights before making that functionality visible in the UI. However, applications need to perform the same access control checks on the server when each function is accessed. If requests are not verified, attackers will be able to forge requests in order to access functionality without proper authorization.
A8 - CROSS-SITE REQUEST FORGERY (CSRF)
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.
A9 - USING COMPONENTS WITH KNOWN VULNERABILITIES
Components, such as libraries, frameworks, and other software modules, almost always run with full privileges. If a vulnerable component is exploited, such an attack can facilitate serious data loss or server takeover. Applications using components with known vulnerabilities may undermine application defenses and enable a range of possible attacks and impacts.
A10 – UNVALIDATED REDIRECTS AND FORWARDS
Web applications frequently redirect and forward users to other pages and websites, and use untrusted data to determine the destination pages. Without proper validation, attackers can redirect victims to phishing or malware sites, or use forwards to access unauthorized pages.
