Once your network is set up securely, you must continue to be vigilant.

Whether it be an innocent user’s risky behavior or an actual break-in, it is the IT professional’s responsibility to know what is happening on their network. Labs in this category explore how to identify systems on a network and the services they provide—either intentionally, through misconfiguration, or by malicious action.

### Identifying Live Machines and Services on an Unknown Network

Students will use tools such as nmap, unicornscan, and fping to identify systems on a local network, including both Unix and Windows targets. Students will identify the operating systems these systems are running, as well as the types of network services they are providing.

##### Prerequisites
• Familiarity with the Unix/Linux command line
• Basic networking concepts (TCP/IP, DNS, etc.)
##### Expected Duration

2 hours, self-paced. Pause and continue at any time.

2 CPEs awarded on successful completion.

$79 for 6 months of access. Free if you are a subscriber to any package that includes this lab. This lab is also available as part of the CYRIN Network Monitoring and Recon Package as well as the CYRIN Cyber Range All Access Package. ### Service Identification I Students will use multiple tools to identify services, including software package and version information, running on unknown systems. Network services to be targeted will include those running on non-standard ports or behind firewall rules. ##### Prerequisites • Familiarity with the Unix/Linux command line • Basic networking concepts (TCP/IP, DNS, etc.) ##### Expected Duration 2 hours, self-paced. Pause and continue at any time. 2 CPEs awarded on successful completion. ##### Cost$79 for 6 months of access. Free if you are a subscriber to any package that includes this lab.

### Service Identification II

Students will build on the Service Identification I exercise to use service-specific information-gathering tools. Students will gather vendor, software, and version information, as well as any configuration information available remotely. Students will then use scripting tools to automate this process.

##### Prerequisites
• Familiarity with the Unix/Linux command line
• Basic networking concepts (TCP/IP, DNS, etc.)
##### Expected Duration

Students will learn to configure log forwarding on the clients, and log rotation and filtering on the server. They will also learn to use Logwatch to analyze logs and fail2ban to automatically respond to suspicious activity found in the logs. ##### Prerequisites • Familiarity with the Unix/Linux command line • Basic networking concepts (TCP/IP, DNS, etc.) ##### Expected Duration 2 hours, self-paced.

### Log Analytics with Splunk

In this lab the student will learn how to configure and securely run the Splunk Enterprise security information collection and analysis platform. The objective of the lab is to deploy multiple instances of Splunk data forwarders through a deployment server and analyze the logs received from the servers. The student will write custom scripts to generate logs, create both visual and textual reports, organize these reports into a single dashboard, and learn to recognize malicious activity.

##### Prerequisites
• Ability to use a command line editor (vi, vim, nano, or emacs).
• Familiarity with the Linux and Windows environment and command line tools.
• Basic understanding of shell scripting in BASH and PowerShell.
• Intermediate understanding of networking concepts and services (TCP/IP, SSH, ...).
##### Expected Duration

2 hours, self-paced. Pause and continue at any time.

In this lab, Elastic Stack will be used for log analytics. Students will learn to set up and run the Elasticsearch, Logstash and Kibana components of Elastic Stack. Multiple computers in a small network will forward their logs to a central server where they will be processed by Elastic Stack. Student will use Kibana to view logs, filter them and set up dashboards. Information in the logs will be used to identify and block an on-going attack. ##### Prerequisites • Basics of Linux/Unix shell commands • Some familiarity with the concepts of sudo and ssh ##### Expected Duration 2 hours, self-paced. Pause and continue at any time. 2 CPEs awarded on successful completion. ##### Cost$79 for 6 months of access. Free if you are a subscriber to any package that includes this lab.
