问题 How do I use Spring Security in a standalone application. I just need to use the Authentication portion of Spring Security. I need to authenticate users against Windows Active Directory. There are lots of examples in the web for using spring security in Servlets but couldn't find much for using them in standalone applications. I am only looking for something to complete this method boolean isValidCredentials(String username, String password) { //TODO use spring security for authentication

问题 Is ngrok a safe tool to use? I was reading a tutorial which recommended to use ngrok test API responses that I make to outside services that need to connect to my endpoints also. 回答1: There is no source code available for Version 2.0, considering it started as an open source project in 2014. I am suspect of any code that opens a tunnel to my localhost from the cloud. Pretty scary stuff especially without source code! 回答2: I found good rating, but vacuous information here: http://www

问题 While there appears to some documentation on how to expose JMX through various firewall and tunneling schemes, I sort of want the opposite. I want to ensure that JMX is only accessible to local machine. Unfortunately it appears that the "out of the box" management options do not allow restricting the ports to a local interface and netstat shows them listening on any/all interfaces. http://java.sun.com/javase/6/docs/technotes/guides/management/agent.html#gdevf I have to admit I am bewildered

问题 My roles are stored in the database and I am trying to load them dynamically upon login. What I'm doing is querying for the roles and setting them on the user object in my user provider as seen here: public function loadUserByUsername($username) { $q = $this ->createQueryBuilder('u') ->where('u.username = :username') ->setParameter('username', $username) ->getQuery() ; try { // The Query::getSingleResult() method throws an exception // if there is no record matching the criteria. $user = $q-

问题 Does https connection secure cookies and prevents XSS attacks. I have a simple blog that allows users to enter JavaScript code as an input. I want to allow Javascript input by the user while still preventing XSS attacks and cookie stealing. Does https help secure cookies. I only found few sites that talks about this and still a bit unclear. 回答1: HTTPS can prevent a man-in-the-middle attack, not XSS. Unfortunately the session cookie is not secure with this alone, one can request a page with

问题 I wish to know which of these two options is the more secure one to use: #define MAXLEN 255 char buff[MAXLEN + 1] sprintf(buff, "%.*s", MAXLEN, name) snprintf(buff, MAXLEN, "%s", name) My understanding is that both are same. Please suggest. 回答1: The two expressions you gave are not equivalent: sprintf takes no argument specifying the maximum number of bytes to write; it simply takes a destination buffer, a format string, and a bunch of arguments. Therefore, it may write more bytes than your
