问题 I have a backing bean ( somebean ) with three boolean properties a , b , and c , each has a getter and setter. I have a form which looks like this: <h:outputText rendered="#{somebean.b}"> B is true </h:outputText> <h:form id="blah"> <h:inputHidden value="#{somebean.a}" id="a"/> <h:commandLink id="zzzz" value="do it" action="#{somebean.doIt}"/> </h:form> Which of the three properties a , b , and c can be set by the client? I tried adding b=true and c=true to the POST request, but SomeBean.setB

问题 Should one really use external commands while coding in Perl? I see several disadvantages of it. It's not system independent plus security risks might also be there. What do you think? If there is no way and you have to use the shell commands from Perl then what is the safest way to execute that particular command (like checking pid, uid etc)? 回答1: It depends on how hard it is going to be to replicate the functionality in Perl. If I needed to run the m4 macro processor on something, I'd not

问题 I'm running Jenkins in a local trusted environment where I'm trying to run this pipeline. This Jenkinsfile is checked into git. #!groovy node('master') { def ver = pomVersion() echo "Building version $ver" } def pomVersion(){ def pomtext = readFile('pom.xml') def pomx = new XmlParser().parseText(pomtext) pomx.version.text() } The first few times I ran the build, I needed to manually approve changes (Jenkins->Mange Jenkins-> In-process Script Approval). Now I get this Exception and there is

问题 What are the security considerations of using --allow-external or --allow-all-externals options of pip ? The documentation sections where these options are described (pip install, pip wheel) are very terse and do not explain the dangers of using them. I couldn't also find any resource on the Internet that would do so either. 回答1: I have asked this question on the FreeNode #pip channel. The following is my interpretation of the replies I've got there. Thanks go to agronholm and dstufft from

问题 I am very new to iPhone development. I downloaded the iPhoneHTTPServer application from bellow link. https://github.com/robbiehanson/CocoaHTTPServer/tree/master/Samples/iPhoneHTTPServer It works fine for HTTP request. Now I want to make it as a secure server. (use HTTPS) for that I have override following two methods in MyHTTPConnection.m I am sure about changes in this method: /** * Overrides HTTPConnection's method **/ - (BOOL)isSecureServer { // Create an HTTPS server (all connections will

问题 This is related to another question I asked. In summary, I have a special case of a URL where, when a form is POSTed to it, I can't rely on cookies for authentication or to maintain the user's session, but I somehow need to know who they are, and I need to know they're logged in! I think I came up with a solution to my problem, but it needs fleshing out. Here's what I'm thinking. I create a hidden form field called "username", and place within it the user's username, encrypted. Then, when the

问题 I cannot obtain a (private) key from KeyStore on Android. Problem occurs mainly on Samsung devices (S6, S6 Edge) and Android 6. android.security.KeyStoreException: Invalid key blob is thrown when following line is called (where alias is name for store key). KeyStore.PrivateKeyEntry privateKeyEntry = (KeyStore.PrivateKeyEntry)keyStore.getEntry(alias, null); The KeyStore itself is obtained by KeyStore.getInstance("AndroidKeyStore"); And key is generated by the following method: private static

问题 Using @Autowired public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception { auth.inMemoryAuthentication().withUser("dba").password("root123").roles("ADMIN","DBA"); my example works fine. For example for http.authorizeRequests() // ... .antMatchers("/db/**").access("hasRole('ADMIN') and hasRole('DBA')") .and().formLogin() .and().exceptionHandling().accessDeniedPage("/Access_Denied"); If I have changed inMemoryAuthentication to spring jdbc default - i got an role
