Page 1 of 4 CCNA SecurityChapter 1 Lab A: Researching Network Attacks and Security Audit ToolsObjectives Part 1: Researching Network Attacks Research network attacks that have occurred. Select a network attack and develop a report for presentation to the class. Part 2: Researching Security Audit Tools Research network security audit tools. Select a tool and develop a report for presentation to the class. Background/Scenario Network attacks have resulted in the loss of sensitive data and significant network downtime. When a network or the resources in it are inaccessible, worker productivity can suffer, and business income may be lost. Attackers have developed many tools over the years to attack and compromise the networks of organizations. These attacks take many forms, but in most cases, they seek to obtain sensitive information, destroy resources, or deny legitimate users access to resources. To understand how to defend a network against attacks, an administrator must first identify network vulnerabilities. Specialized security audit software developed by equipment and software manufacturers can be used to help identify potential weaknesses. In addition, the same tools used by attackers can be used to test the ability of a network to mitigate an attack. After the vulnerabilities are known, steps can be taken to help mitigate the network attacks. This lab provides a structured research project that is divided into two parts: Researching Network Attacks and Researching Security Audit Tools. You can elect to perform Part 1, Part 2, or both. Let your instructor know what you plan to do so to ensure that a variety of network attacks and vulnerability tools are reported on by the members of the class. In Part 1, you research various network attacks that have actually occurred. You select one of these and describe how the attack was perpetrated and how extensive the network outage or damage was. You also investigate how the attack could have been mitigated or what mitigation techniques might have been implemented to prevent future attacks. You prepare a report based on a predefined form included in the lab. In Part 2, you research network security audit tools and investigate one that can be used to identify host or network device vulnerabilities. You create a one-page summary of the tool based on a predefined form included in the lab. You prepare a short (5–10 minute) presentation to present to the class. You may work in teams of two with one person reporting on the network attack and the other reporting on the security audit tools. Each team member delivers a short overview (5–10 minutes) of their findings. You can use live demonstrations or PowerPoint to summarize your findings.
