The learning objective of this lab is for students to gain first-hand experience with a variant of the bufferoverflow attack; this attack can bypass a protection scheme currently implemented in major Linux operating systems. A common way to exploit a buffer-overflow vulnerability is to overflow the buffer with malicious shellcode, and then cause the vulnerable program to jump to the shellcode that is stored in the stack.

This exercise explores basic network routing concepts in a Linux environment. These include use of the route command to modify Linux routing tables, defining a DNS server in the /etc/resolv.conf file, and an example of using Linux iptables to implement Network Address Translation (NAT).

The learning objective of this lab is for students to understand how environment variables affect program and system behavior. Environment variables are a set of dynamic named values that can affect the way running processes will behave on a computer.

SQL injection is a code injection technique that exploits the vulnerabilities in the interface between web applications and database servers. The vulnerability is present when user’s inputs are not correctly checked within the web applications before being sent to the back-end database servers.

This lab illustrates the use of an SSH agent to manage private keys used to authenticate to SSH services on Linux computers. The goal is to allow a user to use SSH to securely authenticate from the client to a local server, and then from the local server to a remote server, without providing either a password or a passphrase, (after initial setup and initialization of an SSH Agent).

Challenge 157
Mountain Climber

Stacks Image 2543
The scenario of the lab is that an attacker has done appropriate reconnaissance to find out the IP addresses, host names and at least one userid on each host, on a path from base to hostd. You might think the the attacker could set up a direct ssh connection to hostd but the gateways along the way, except for gw4 don’t know about hostd’s network and hence wouldn’t be able to route the packets. Hence the need for the tunnel.

This Labtainer explores the use of SSH from a client computer to connect securely to a server using public and private key pairs. In this example, mere possession of the private key is sufficient to access the remote host. In general, password-protected private keys are more secure.

Challenge 159
Special Invasion

This lab requires that you use SSL certificates to authenticate devices on a simulated industrial control system network shared by Programmable Logic Controlers (PLCs) and Human Machine Inteface (HMI) devices. The concepts covered by this lab are applicable to pairs of clients and servers, e.g., a web broswer and a web server.

This exercise introduces management of users and groups on a Unix system. The lab includes the following objectives:
 Add users to a shared system.
 Define a group on the system, and assign users to that group.
 Observe how user and group IDs can affect access to files.
 Observe a limitation of discretionary access controls.
 Grant a user sudo or superuser privileges.

Challenge 165
Angel Alert

Stacks Image 2374
This Labtainer exercise illustrates a simple host-to-host vpn implemented with openvpn, and a static shared key. The example network includes a client and a server with a router between them. The server offers a simple HTTP service, and the student will use wget on the client to retrieve html files from the server.

Behavioral targeting is a type of online advertising where ads are displayed based on the users web-browsing behavior. The user leaves a trail of digital foot prints moving from one website to the other. Behavioral targeting anonymously monitors and tracks the sites visited by a user. When a user surfs internet, the pages they visit, the searches they make, location of the user browsing from, device used for browsing and many other inputs are used by the tracking sites to collect data.

Challenge 167
Alien Emergency

Stacks Image 2335
The objective of this lab is to help students understand the Cross-Site Request Forgery (CSRF or XSRF) attack. A CSRF attack involves a victim user, a trusted site, and a malicious site. The victim user holds an active session with a trusted site while visiting a malicious site. The malicious site injects an HTTP request for the trusted site into the victim user session, causing damages.

Cross-site scripting (XSS) is a type of vulnerability commonly found in web applications. This vulnerability makes it possible for attackers to inject malicious code (e.g. JavaScript programs) into victim’s web browser. Using this malicious code, the attackers can steal the victim’s credentials, such as session cookies. The access control policies (i.e., the same origin policy) employed by browsers to protect those credentials can be bypassed by exploiting the XSS vulnerability. Vulnerabilities of this kind can potentially lead to largescale attacks.
