Applocker: Application Control Policy for Windows Network Protection Application whitelist is a powerful technology that can protect our computers from unknown malware, but it has never been used. One of the main reasons is that it is difficult to configure and maintain, and the other is that there are quite a number of bypass technologies, so it cannot effectively prevent identified attackers. Today, let's take a look at the built-in windows AppLocke

The blacklist (the addition and deletion of the white list are the same as those of the black list, so we will not repeat it here), the listener switch, the timed interception switch, and the selection of the interception mode are enabled, the following describes how to implement the core function, that is, the interception function. Main Ideas: 1. There are two main bloc

Simple defense against multiple malicious server submissions Background: The continuous sending or malicious submission of requests by machines puts a lot of pressure on the server. The optimal strategy for this attack is to determine the number of submissions and generate dynamic verification codes, that is, the verification code is displayed when the ip address is repeatedly sent for N times within the specified time. The following is a simple process of identifying ip addresses, recording and

browsers is that they cannot distinguish whether scripts are from their own applications or malicious injection by third-party attackers, which is precisely exploited by attackers. For example, Google's+ 1The button will load and execute a script from the https://apis.google.com/js/plusone.js that we trust, but we cannot expect the browser to differentiate scripts from api.google.com from safe, insecure from apis.evil.example.com. All files are downloaded and executed by the browser. CSP define

so-called whitelist. Note: If the same action method is specified for the blacklist and whitelist, this method will not be blocked. The main method of the methodinterceptor class: protected abstract string dointercept (actioninvocation Invocation): The subclass that inherits this class must override this method and implement the interceptor logic.

. However, this sandbox is different from the Java SecurityManager sandbox, from the code, we can see that this sandbox is a "Shallow" sandbox, which is used to judge whether the expression is legal in terms of expression semantics based on the blacklist and whitelist. The specific code process is as follows: The whitelist can be called as follows: From the preceding
