Network Defense projects examples using omnet++

Network defense projects has encompass making and mimicking systems or mechanisms to protect a network from numerous cyber threats, like attacks, intrusions, or unauthorized access. We can feign several network defense strategies and estimate their efficiency in obtaining network infrastructure by using OMNeT++. Given below are several network defense project instances that can be executed using OMNeT++:

1. Firewall Implementation and Testing

• Objective: Mimic a firewall that strainers network traffic based on predefined security rules to avoid unauthorized access.
• Implementation: Make a network where traffic passes via a firewall module. Execute the rules to block or allow traffic based on criteria like IP address, port number, or protocol. The firewall inspects incoming and outgoing packets and applies the security rules.
• Extension: Examine the firewall’s effectiveness by mimicking numerous kinds of attacks, such as IP spoofing, port scanning, or DDoS attacks. Compute the impact of the firewall on network performance and security.

2. Intrusion Prevention System (IPS)

• Objective: Feign an Intrusion Prevention System (IPS) that not only identifies but also actively blocks malicious traffic in real-time.
• Implementation: Design a network where an IPS module monitors traffic for signs of intrusion like known attack signatures or behavioral anomalies. When an intrusion is identified, the IPS takes immediate action, such as dropping malicious packets or blocking suspicious IP addresses.
• Extension: Execute several intrusion detection methods like signature-based, anomaly-based and liken the efficiency of the IPS in avoiding numerous kinds of attacks. Evaluate the trade-offs among detection accuracy and response time.

3. DDoS Attack Mitigation System

• Objective: Mimic a system to detect and mitigate Distributed Denial of Service (DDoS) attacks, make sure network availability during an attack.
• Implementation: Form a network where numerous nodes attempt to flood a target server with traffic (DDoS attack). Apply a defense mechanism that detects the excessive traffic and mitigates the attack by rate-limiting, filtering, or rerouting traffic.
• Extension: Test with various DDoS mitigation strategies, like scrubbing centers, load balancing, or traffic diversion. Compute the efficiency of each strategy in maintaining network performance during the attack.

4. Network Segmentation for Security

• Objective: Mimic network segmentation as a defense strategy to limit the spread of attacks in a network by dividing it into smaller, isolated segments.
• Implementation: Build a network topology with many segments, each isolated from the others using firewalls, VLANs, or subnets. Execute security policies that control traffic among segments, permitting only authorized communication.
• Extension: Feign an attack in one segment like malware infection and establish how segmentation avoids the attack from spreading to other parts of the network. Calculate the influence of segmentation on network performance and security.

5. Network Access Control (NAC)

• Objective: Mimic a Network Access Control (NAC) system that applies security policies to control which devices can access the network and what they can do once linked.
• Implementation: Execute a NAC system that needs devices to authenticate before getting network access. The NAC applies policies based on device type, user credentials, and security posture such as up-to-date antivirus software.
• Extension: Feign scenarios where unauthorized devices attempt to associate to the network and consider how the NAC system responds. Assess the system’s efficiency in maintaining network security and integrity.

6. Encryption-Based Network Defense

• Objective: Emulate the use of encryption to defend data in transfer in a network, make sure confidentiality and integrity.
• Implementation: Form a network where data is encoded before transmission using protocols such as SSL/TLS or IPSec. Execute encryption and decryption processes at the sender and receiver nodes, correspondingly.
• Extension: Mimic different kinds of attacks, like man-in-the-middle (MitM) or replay attacks, and establish how encryption avoids these attacks. Examine the impact of encryption on network performance and security.

7. Endpoint Security and Defense

• Objective: Emulate endpoint security measures that defend individual devices in a network from threats such as malware, unauthorized access, or data breaches.
• Implementation: Perform the security measures on network endpoints such as workstations, servers, like antivirus software, firewalls, and encryption. The system observes endpoint activities and blocks any suspicious behaviour.
• Extension: Feign scenarios such as a malware infection or an attempted data breach on an endpoint, and assess how well the security measures identify and avoid the threat. Liken the effectiveness of various endpoint security solutions.

8. Secure Network Protocols Implementation

• Objective: Feign the execution of secure network protocols that defend communication from several threats, like eavesdropping, tampering, or impersonation.
• Implementation: Execute secure versions of general protocols, such as HTTPS (secure HTTP), SFTP (secure FTP), and SSH (secure shell). Nodes communicate using these protocols, make sure that all data transmitted is encrypted and authenticated.
• Extension: Mimic attacks on these protocols, like SSL stripping or SSH brute force, and show how the secure protocols defend versus these attacks. Compute the trade-offs among security and performance when using secure protocols.

9. Threat Intelligence-Based Network Defense

• Objective: Feign a network defense system that incorporates threat intelligence feeds to proactively block known malicious IP addresses, domains, and other threat indicators.
• Implementation: Execute a system that endlessly updates its firewall rules, IDS/IPS signatures, and other defense mechanisms based on real-time threat intelligence. The system automatically blocks traffic related with known threats.
• Extension: Mimic the network’s response to a developing threat detected by the threat intelligence feed and calculate the system’s ability to avoid the threat from impacting the network. Liken the effectiveness of using static defense measures against dynamic threat intelligence-based defense.

10. Behavioural Analytics for Network Defense

• Objective: Emulate a network defense system that uses behavioural analytics to find and react to threats based on deviations from typical network behaviour.
• Implementation: Execute a behavioral analysis module that observes traffic patterns, user activities, and system performance over time to found a baseline of “normal” behavior. The system raises alerts and activates defenses when significant deviations happen.
• Extension: Experiment the system versus numerous attacks, like insider threats, lateral movement, or data exfiltration, and calculate how well it detects and responds to these threats. Examine the impact of behavioural analytics on the network’s complete security posture.

11. Honeypot Deployment for Network Defense

• Objective: Mimic the deployment of honeypots in a network to lure attackers, collect intelligence on their methods, and strengthen complete network defense.
• Implementation: Use honeypot nodes within the network that mimic vulnerable systems or services. Observe and log all interactions with the honeypots to find attack patterns, tools, and methods used by adversaries.
• Extension: Examine the data gathered by the honeypots to advance network defenses, like updating firewall rules or improving IDS signatures. Simulate numerous kinds of honeypots like low-interaction vs. high-interaction and liken their efficiency in attracting and detecting attackers.

12. Network Defense Using Artificial Intelligence

• Objective: Mimic a network defense system that uses artificial intelligence (AI) and machine learning to guess and react to potential threats in real-time.
• Implementation: Execute an AI-driven defense module that evaluates network traffic, system logs, and user behaviour to identify potential threats. The AI system studies from past incidents and endlessly expands its threat detection and response capabilities.

13. Zero Trust Network Access (ZTNA) Implementation

• Objective: Feign a Zero Trust Network Access (ZTNA) model where no device or user is trusted by defaulting, even if they are inside the network perimeter.
• Implementation: Execute a ZTNA model where every access request is authenticated, authorized, and encrypted before being allowed. The system endlessly observes and validates user and device identities during the session.
