security

问题 I am creating a publicly available API using API Gateway which is backed with lambda functions to do some processing. I have secured it with a custom security header that implements hmac authentication with timestamp to protect against replay attacks. I understand that API Gateway protects against DDOS attacks through its high availability, but any invalid requests will still be passed to the lambda authentication function. So, I guess an attacker can submit invalid unauthenticated requests

问题 My application uses Spring Security, and my client requires: users to be able to automatically login after signup. an admin to login as any user without knowing their password. So I need to figure out how to login as any user automatically without knowing their password. How can this be accomplished using Spring Security? 回答1: To get this to work, I had to: Configure a reference to the UserDetailsService (jdbcUserService) <authentication-manager> <authentication-provider> <jdbc-user-service

问题 I can't wrap my brain around why this isn't work... I really think it should be. Please help. Here is the error I get: signature_invalid base_string:GET&https%3A%2F%2Fwww.google.com%2Faccounts%2FOAuthGetRequestToken&oauth_callback%3Dhttp%253A%252F%252Fnoveis.net%252Fauthsub%252Findex.php%26oauth_consumer_key%CONSUMER KEY HERE%26oauth_nonce%3D3bafa031c03f6d1590f2539091245270%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1282159845%26oauth_version%3D1.0%26scope%3Dhttps%253A%252F

问题 Now that there are a couple of neat canvas demo's of both classic platform and even 3D fps games in HTML5, the next step might be to try developing a multiplayer HTML5 game. HTML5 socket support makes this relatively straight-forward, but with client-side source being viewable by anyone in the browser, what are some solutions for basic game security features for a HTML5-frontend multiuser game -- such as being able to prevent a faked high-score submit ? 回答1: The simple answer is: You can't

问题 Looking to improved the security of my Android app to flag if the .apk has been extracted, modified, repacked and resigned. Here's article from Zdnet noting the issue link1. The concern is if the app is targeted by hackers they could add malicious code and upload to an alternate app store and dupe users in to downloading it. So I'm thinking code to verify a checksum of the apk or signing certificate? I appreciate the app code could be repacked and any security code removed, but it does

问题 I have a problem where I have a frameset consisting of a parent frame loaded from one domain and a contained frame from a different domain. The contained domain also sets a cookie before the frameset is loaded. However, because of the 'same orgin' policy, enforced by most browsers, a contained frame will not pass cookies if it is not from the same domain as the parent. Unfortunately I have no control over the parent frame (or its url) and the url for the contained frame is effectively static.

问题 This is a follow-up of a question I asked earlier this morning (posted here.) Following the instructions provided, I've managed to query my SQL Server 2000 database for a SID associated with an AD Group. The SID, however, looks like this: 0x0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF01234567 What can I do to obtain the name of the AD Group referenced by the SID? I've tried googling PowerShell scripts, however, most of their examples of SIDs look like this: S-1-5-21-1454471165-1004335555

问题 In java to pass the values between some classes we can use System.setProperty. But using System.getProperties() we can get all the system properties. So if i use any third party API's means they can also access my properties and also they can change. SO is System.setProperty safe ? 回答1: It depends what you mean by safe. It is good practice 1 treat the System Properties object as read only, but you can't rely on 3rd-party libraries to do that. If you are worried about "trusted" 3rd-party code
