ASM PROTECTS AGAINST TOP APP VULNERABILITIES OWASP Top 10 Web Application Security Risks: 1. Injection 2. Cross-Site Scripting (XSS) 3. Broken Authentication and Session Management 4. Insecure Direct Object References 5. Cross-Site Request Forgery (CSRF) 6. Security Misconfiguration 7. Insecure Cryptographic Storage 8. Failure to Restrict URL Access 9. Insufficient Transport Layer Protection 10. Unvalidated Redirects and Forwards Source: www.owasp.org

How Does ASM Work? Security at application, protocol and network level Request made Security policy checked Server response Content scrubbing Application cloaking Response delivered Security policy applied Actions: Log, block, allow BIG-IP enabled us to improve security instead of having to invest time and money to develop a new, more secure application.

Three Ways to Build an ASM Policy Security policy checked Security policy applied Dynamic policy builder Automatic No knowledge of the app required Adjusts policies if app changes Manual Advanced configuration for custom policies Integration with app scanners Virtual patching with continuous application scanning

How was your Heartbleed?

Heartbleed and F5 If F5 has been terminating your SSL for the last two years your applications have been safe from Heartbleed. Upgrade /hotfix your BIG-IP if If you have version 11.5.0 If you have version 11.5.1 Your BIG-IPs were vulnerable if You were using version 11.5.0 or 11.5.1 and You were using the COMPAT stack or Your management interface was accessible to the Internet. Use No irule if You are terminating SSL using a clientssl profile at the BIG-IP. Use clientside irule if You are passing SSL through the BIG-IP to vulnerable servers Use serverside irule if You have vulnerable servers accessible from Internet and intranet F5 Networks, Inc 31

Crypto s Dirty little secret SSL is always this close to being broken SSLv2 MD5 SHA1 RC4 TLS1.0 (BEAST) TLS1.1 (CRIME) TLS1.2 (Heartbleed)

What is SAML? Its Web Single Sign-On (federated auth) Eliminates Need for Multiple Passwords/Password Databases in Multiple Locations. I.e., Keep your directory behind your firewall Enables enterprise apps in the Cloud

SAML lets you do this with your apps Think of it as the enterprise version of OAuth

SAML - Claims Based Authentication The process of authenticating a user based on a set of claims about its identity contained in a trusted token. Such a token is often issued and signed by an entity that stores and maintains this information about the user Claims in Action: 1) Illinois has my information and driving test results 2) I carry an Illinois driver s license 3) Georgia does not have my information, but they trust Illinois 4) So I am allowed to drive in Georgia.
