Similar to unraveling a math word problem, Security Intelligence: A Practitioner's Guide to Solving Enterprise Security Challenges guides you through a deciphering process that translates each security goal into a set of security variables, substitutes each variable with a specific security technology domain, formulates the equation that is the deployment strategy, then verifies the solution against the original problem by analyzing security incidents and mining hidden breaches, ultimately refines the security formula iteratively in a perpetual cycle. You will learn about:
• Secure proxies - the necessary extension of the endpoints • Application identification and control - visualize the threats • Malnets - where is the source of infection and who are the pathogens • Identify the security breach - who was the victim and what was the lure • Security in Mobile computing - SNAFU
With this book, you will be able to:
• Identify the relevant solutions to secure the infrastructure • Construct policies that provide flexibility to the users so to ensure productivity • Deploy effective defenses against the ever evolving web threats • Implement solutions that are compliant to relevant rules and regulations • Offer insight to developers who are building new security solutions and products

Application‐specific security policies, and www.it-ebooks.info Chapter 1 ■ Fundamentals of Secure Proxies 15 to intercept and decrypt SSL traffic. The NGFW includes all of the capabilities of the traditional firewall and incorporates the full functionality of a signature‐ based IPS. Another key characteristic of the NGFW is its inline deployment as a bump‐in‐the‐wire. In addition, the NGFW can collaborate with external services to incorporate additional security‐relevant data and feeds.
Request against known attacks. Once the request passes the validation phase, the proxy then distributes the request to a server based on some preconfigured load‐balancing algorithms, thus reducing the chance of overloading a specific server. With a reverse proxy the servers do not have to individually implement various security features against threats such as cross‐site scripting and SQL injection. The reverse proxy can also centralize the authentication implementation. Challenges of.
URL (⑥) causes HTTP‐ and Facebook‐ related conditions and properties to be added into that same policy ticket (⑦). While Mary visits her friends’ pages, the transaction is categorized as a Facebook application. Finally, when Mary clicks the “Games” button and then selects the “Play Now” option for “Candy Crush”, the policy engine detects this action after observing the HTTPS request to https://apps.facebook.com/candycrush (⑧); thereafter, the policy engine deposits additional conditions and.
Policies. The proxy runs yet another checkpoint when the server responses are received (⑨ or ⑩ or ). The proxy consults the policy and forwards the content to an off‐box virus scanner for clean content verification. In addition, the proxy does not cache the returned content. Finally, at the proxy may rewrite or transform a subset of the content before responding to the original client request. This example illustrates that the placements of these checkpoints in the processing path are specific to.
In previous sections, lists of such URLs are available from malware databases online. The web crawler first needs to visit those URLs and obtain a copy of the pages behind the URLs for processing. It is worth noting that the crawler extracts common features that are indicators of malicious webpages, which is a different approach from the dynamic content rating system we discussed earlier. In the latter case, the rating is based on the analysis of textual content that is visible to the end user,.
