Drop Project Security Manager

Custom Security Manager used by Drop Project to sandbox students' submissions.

Current checks include:

• Calling System.exit()
• Trying to read a file outside the working dir (or one of its subdirs)
• Trying to write a file outside the working dir (or one of its subdirs)

Any of these will be detected by the Security Manager and will lead to a SecurityException being thrown.

How to use

Include the following dependency on your pom file:

<dependency>
    <groupId>org.dropproject</groupId>
    <artifactId>drop-project-security-manager</artifactId>
    <version>0.2.4</version>
</dependency>

Now, just set the security manager when calling your application like this:

java -Djava.security.manager=org.dropproject.security.SandboxSecurityManager YourMainClass

Remarks

Since this usually runs within Drop Project, it is expecting a system property dropProject.maven.repository
