Security experts recently issued a warning that a newly discovered cross-browser attack vulnerability will cause terrible security issues that affect all mainstream desktop platforms, including IE, Firefox, Safari, opera and Adobe Flash. This security threat, called clickjacking, was originally to be announced at the owasp nyc appsec 2008 conference, but vendors including Adobe requested not to disclose this vulnerability until they developed a securi

App Gateway on Azure is a seven-tier load balancing service, and WAF is an extension of App Gateway services. The seven-tier load balancer adds the functionality of the WAF to protect the HTTP service in the background.Azure WAF is based on the WAF functionality implemented by the open source modsecurity owasp core rule sets. Please refer to Modsecurity's website for details: https://modsecurity.org/The current version of Azure support for

Java EE have some excellent built-in security mechanisms, but they don ' t come close to covering all the threats that your AP Plications'll face. Many common attacks like Cross-site Scripting (XSS), SQL injection, Cross-site Request forgery (CSRF), and XML eXternal En Tities (XXE) aren ' t covered at all. Can prevent your Web applications and Web services from being vulnerable to these attacks, but it's going to take some Work and testing. Fortunately, the Open Web Application Security Project

XSS attack and defense XSS attacks: cross-site scripting attacks (Cross Site scripting) that are not confused with abbreviations for cascading style sheets (cascading style Sheets, CSS). A cross-site Scripting attack is abbreviated as XSS. XSS is a computer security vulnerability that often occurs in Web applications, allowing a malicious Web user to embed code in a page that is available to other users. For example, the code includes HTML code and client script. An attacker uses an XSS vulnera

decrypted plaintext. The attacker will reverse any bit in the initialization vector (IV) (1 to 0 to 1 ), the corresponding bits in the plaintext group (the plaintext group obtained after decryption) will also be reversed. For example, if a user named admin logs on and uses the CBC encryption mode, the token is "aaabbbccc999". Now there is an attacker named john, logging on, encrypted in the CBC mode, token is cccbbbccc1111. Now john changes token to "ffcbbbccc1111" and finds that the login name

first thing you need to do is to encode untrusted data in HTML Entity. For example, we often need to put user-submitted data into DIV, P, and TD tags, Which is untrusted and must be encoded in HTML Entity. Many Web frameworks provide HTML Entity-encoded functions. We only need to call these functions, while some Web frameworks seem to be more "intelligent", such as Rails, by default, it can encode HTML Entity for all the data inserted into the HTML page. Although it cannot completely defend aga

OWASP top 10 top 3rd threats: "corrupted authentication and session management". In short, attackers can obtain the sessionID By eavesdropping the user name and password when accessing HTTP, or by session, then impersonate the user's Http access process.Because HTTP itself is stateless, that is to say, each HTTP access request carries a personal credential, and SessionID is used to track the status, sessionID itself is easily listened to on the networ

Translation: how to practice your web application testing skills For those who are learning web application security testing (or just trying to stay sharp) it's often difficult to find quality websites to test one's skills. there are a few scattered around the Internet (see the link in the notes section below) but it wocould be nice to have a solid collection of test sites all in one place. Aside from finding them all, another problem with most of these sites is that you can download them for f

must understand that it is not enough to use JavaScript Functions on the client to detect and filter illegal input to Build Secure WEB applications. As described above, attackers can easily use tools to bypass JavaScript verification or even SSL encryption to input malicious data. Encoding dynamic content at the output end can only provide a dual protection function. More importantly, the server should verify the input. PHP provides functions such as strpos (), strstr (), and preg_match () to d

Ensure Ajax applications Program Security is a new challenge for anyone who develops or manages Web Services. The core of most Ajax applications is the Javascript XMLHTTPRequest object, which allows web pages to independently connect to users' web servers and extract cross-origin content. When a service-oriented architecture is combined with other software services that are loosely integrated, this feature has serious security problems. Although Ajax does not create new security vulnerabilities
