Your organization has been very concerned with the recent data breaches across the United States. The chief executive officer (CEO) has summoned his executives to look at IDSs/IPSs to help protect the organization’s computing infrastructure. As an IT manager for the organization, you have been asked to attend the meeting with your chief information officer (CIO). In the meeting, your CIO projected the network diagram and announced that the IT department will purchase five IDS/IPS. There are three main types of IDSs/IPSs—host-based intrusion detection system (HIDS), network-based intrusion detection system (NIDS), and wireless intrusion detection system (WIDS). In your initial post, select a total of five IDSs/IPSs from the three main types of IDSs/IPSs, and explain how each of your selections will protect the infrastructure depicted in the diagram.
In addition, you have been tasked with explaining to a team of executives, in layman’s terms, where you will strategically place the five IDSs/IPSs and how each placement will best serve the organization. For this portion of the interactive assignment, you will create a five-minute maximum screencast presentation of a PowerPoint that provides this explanation. For the screencast portion you may use any screencasting platform you wish. (Quick-start guides for Screencast-O-Matic and Jing are provided for your convenience.)
Create your PowerPoint presentation including the following elements.
State the problem from the CEO’s perspective.
Explain in layman’s terms the design and use of IDS/IPS within the network, including the specific locations for each chosen system.
Justify the use of the chosen IDSs and how these will protect the various subnets of the network.
Explain how each of these solutions presented can address the CEO’s concerns.
Include visual enhancements in your presentation. These may include appropriate images, a consistent font, appropriate animations, and transitions from content piece to content piece and slide to slide.

Slide 3: What is an IDS/IPS?
Layman's Explanation:
"Imagine having a security guard constantly monitoring your network for suspicious activity. That's essentially what an IDS/IPS does. It's like a digital watchdog that watches over your network traffic, looking for patterns or behaviors that indicate potential attacks."
Slide 4: Types of IDS/IPS
Host-based Intrusion Detection System (HIDS):
"HIDS resides on individual computers, monitoring their activities for anomalies. It's like having a security camera inside each device."
Network-based Intrusion Detection System (NIDS):
"NIDS sits on the network, inspecting data packets as they flow through. It's like having a security guard stationed at every network junction."
Wireless Intrusion Detection System (WIDS):
"WIDS specifically monitors wireless networks, detecting unauthorized access attempts and rogue devices."
Slide 5: Strategic IDS/IPS Placement
Layman's Explanation:
"Just as you would position security guards strategically throughout a building, we'll place our IDSs/IPSs at critical points in our network to maximize their effectiveness."
HIDS Placement:
"HIDS will be installed on critical servers and workstations, providing granular protection for sensitive data."
NIDS Placement:
"NIDS will be positioned at network choke points, monitoring all incoming and outgoing traffic."
WIDS Placement:
"WIDS will be deployed in areas with wireless access, safeguarding our wireless networks from intrusion."
Slide 6: Protecting Various Subnets
Layman's Explanation:
"Our network is divided into subnets, each serving a specific purpose. We'll tailor our IDS/IPS deployment to ensure comprehensive protection for each subnet."
Protecting the Data Center Subnet:
"HIDS will monitor servers in the data center, protecting our sensitive financial and customer data."
Protecting the Administrative Subnet:
"NIDS will safeguard the administrative subnet, preventing unauthorized access to critical management systems."
Protecting the Guest Subnet:
"WIDS will secure the guest subnet, ensuring that visitors' devices cannot pose a threat to our internal network."
Slide 7: Addressing the CEO's Concerns
Layman's Explanation:
"By implementing a strategic IDS/IPS deployment, we can effectively address the CEO's concerns about network security."
Preventing Data Breaches:
"IDS/IPS will detect and alert us to potential intrusion attempts, allowing us to take immediate action to prevent data breaches."
Enhancing Network Resilience:
"By monitoring network traffic for anomalies, IDS/IPS will help us identify and remediate vulnerabilities before they can be exploited."
Safeguarding Sensitive Data:
"Our tailored IDS/IPS deployment will ensure that our most critical subnets and data are protected from unauthorized access."
Slide 8: Conclusion
Layman's Summary:
"By implementing a comprehensive IDS/IPS solution, we can significantly enhance our network security posture and protect our organization's valuable assets from cyber threats."
Benefits Recap:
- Proactive intrusion detection and prevention
- Enhanced network resilience
- Safeguarding of sensitive data
- Addressing the CEO's security concerns
Call to Action:
"I urge the executive team to approve the implementation of this critical cybersecurity initiative to safeguard our organization's future."
Slide 9: Thank You
Expression of Gratitude:
"Thank you for your attention and support in addressing our organization's cybersecurity needs."
