Course Name and Number: _____________________________________________________ Student Name: ________________________________________________________________ Instructor Name: ______________________________________________________________ Lab Due Date: ________________________________________________________________

Overview

In this lab, you explored the common tools available in the virtual lab environment. You

used Wireshark to capture and analyze network traffic and OpenVAS to scan the

network. You reviewed a sample collection of data using NetWitness Investigator,

connected to a remote Windows machine, and explored two file transfer applications,

FileZilla and Tftpd64. You used PuTTY to connect to a Linux machine and ran several

Cisco commands to display statistics for the network interfaces. Finally, you used

Zenmap to perform a scan of the network and created a network topology chart.

Enabling Windows Active Directory and User Access Controls

Course Name and Number: _____________________________________________________ Student Name: ________________________________________________________________ Instructor Name: ______________________________________________________________ Lab Due Date: ________________________________________________________________

Overview

In this lab, you followed the Microsoft approach to securing the CIA triad. You created new user

accounts and security groups, and applied the new user accounts to the security groups, just as

you would in a real world domain. You created nested folders on the remote server and assigned

unique file permissions using the new user accounts and security groups. You modified the

Windows Group Policy enabling each new user account to use remote desktop services to

remotely access the TargetWindows01 server. Finally, you tested the security layers you placed

in the previous parts of the lab by using each new user account to access and modify the nested

folders on the remote server.

Lab Assessment Questions & Answers

1. What are the three fundamental elements of an effective security program for information systems?

2. Of these three fundamental controls, which two are used by the Domain User Admin to create users and assign rights to resources?

3. If you can browse a file on a Windows network share, but are not able to copy it or modify it, what type of access controls and permissions are probably configured?

4. What is the mechanism on a Windows server where you can administer granular policies and permissions on a Windows network using role-based access?

5. What is two-factor authentication, and why is it an effective access control technique?

82 | Lab #3 Enabling Windows Active Directory and User Access Controls

6. Relate how Windows Server 2012 Active Directory and the configuration of access controls achieve CIA for departmental LANs, departmental folders, and data.

7. Is it a good practice to include the account or username in the password? Why or why not?

8. Can a user who is defined in Active Directory access a shared drive on a computer if the server with the shared drive is not part of the domain?

9. When granting access to LAN systems for guests (i.e., auditors, consultants, third-party individuals, etc.), what security controls do you recommend be implemented to

maximize CIA of production systems and data?

Analyzer (MBSA) to assess its security state, and you examined the results of the Microsoft

Baseline Security Analyzer in detail.

Using Encryption to Enhance Confidentiality and Integrity

Course Name and Number: _____________________________________________________ Student Name: ________________________________________________________________ Instructor Name: ______________________________________________________________ Lab Due Date: ________________________________________________________________

Overview

In this lab, you learned how cryptography tools can be used to ensure message and file transfer

integrity and how encryption can be used to maximize confidentiality. You used Kleopatra, the

certificate management component of GPG4Win, to generate both a public and a private key as

both a sender and a receiver. You used the sender’s keys to encrypt a file, sent it to the receiver,

and decrypted it using the receiver’s copy of the keys.

Lab Assessment Questions & Answers

1. If you and another person want to encrypt messages, should you provide that person with your public key, private key, or both?

2. What does Kleopatra allow you to do once it is installed?

3. What key type was used to create the certificate on Kleopatra? What other types of encryption key types are possible?

4. What was the fingerprint generated with your Kleopatra certificate?

5. If someone sends you his public key and you import it into Kleopatra, will he be able to decrypt the encrypted messages you send him?
