To Simulate the intrusion attacks in OPNET has contains the setting network scenarios in which an attacker attempts to open or disrupt the network. Intrusion attacks can contain the network-according attacks such as port scanning, SQL injection, distributed denial of service (DDoS), and unauthorized access attempts. This replication assigns the follow-on effect of network resources, server response times, and classify on how the intrusion detection systems (IDS) might respond to such attacks.
Here’s a step to simulate different kinds of intrusion attacks in OPNET:
Steps to Simulate Intrusion Attacks projects using OPNET
- Set Up OPNET Environment
- Open OPNET Modeler, build a new project, and label it something such as “Intrusion Attack Simulation.”
- To configure the workspace has contains the network with several devices of involving the legitimate clients, target servers, routers, and attacker nodes.
- Design Network Topology
- Model a topology that contains:
- Target servers: This can be web servers, database servers, or application servers that can be targeted through intrusion attacks.
- Client devices: Legitimate devices like as workstations or laptops we replicate the normal network traffic.
- Routers or firewalls: Network infrastructure components to handles the routing and replicate the firewall protection.
- Attacker nodes: Nodes setting to establish their specific intrusion attacks on the target network.
- Connect the nodes to replicate a network layout where attackers are either within the local network (insider threat) or externally positioned we replicate the internet-based threats.
- Configure Legitimate Network Traffic
- Configure the regular transmission among client devices and servers. In Application Configuration, describe the general applications like as:
- HTTP/HTTPS for web access.
- FTP for file transfers.
- SQL Database for database requests (if targeting database intrusion).
- Utilized the Profile configure the permits of this application to client devices we generate normal traffic and deliver a baseline for observing intrusion effects.
- Simulate Different Types of Intrusion Attacks
- Port Scanning Attack
- Objective: Classify open ports on the target server that can be vulnerable to further attacks.
- Configuration:
- Setting the attacker node, we transfer their packets in sequentially for several ports on the target server such as TCP or UDP.
- Describe a high scanning frequency for replication of aggressive scan or a lower frequency for a secret scanning.
- Observation:
- As open to observe the ports for attacker findings. Follow many server workloads increases due to the frequent port probes.
- SQL Injection Attack
- Objective: Assigns or manipulate a database through injecting the malicious SQL queries by vulnerable web applications.
- Configuration:
- Configure the attacker node we transfer HTTP requests encompassing the SQL code for the target web server with database access.
- Involves the SQL commands in the HTTP payload for replication of data extraction, modification, or deletion.
- Observation:
- Observe the database query logs to illustrative the unauthorized queries are processed. Checked the server response periods are error rates and an SQL injection can be high the query load of errors.
- DDoS Attack
- Objective: Overcome the target server or network through extreme traffic leading the resource exhaustion.
- Configuration:
- Utilized their multiple attacker nodes we replication of distributed attack, every transferring the high-frequency requests such as HTTP, ICMP, or UDP for the target.
- Setting the packet size, inter-arrival time, and time to replicate a flood of requests.
- Observation:
- Observe the network throughput, packet loss, and latency on the target server. High resource utilization and released connections are general ensembles a DDoS attack.
- Unauthorized Access (Brute Force) Attack
- Objective: Try to gain the unauthorized access through repeating and effort to the various identification of the target server.
- Configuration:
- Setting the attacker node, we transfer the continuously login requests with several username-password combinations.
- Configure a high request rate we replicate the basic force efforts or decrease the low-frequency attack.
- Observation:
- Observe the authentication logs on the target server. Aspect the repeated login attempts, failed access attempts, and potential lockouts due to the attack.
- Man-in-the-Middle (MITM) Attack
- Objective: Interrupt and potentially modify the data passing among two nodes.
- Configuration:
- Placed the attacker among a client and server we seizure the relay traffic.
- Setting the attacker, we transfer packets among nodes but log or alter their packet data for further investigation.
- Observation:
- Follow on the data seized through the attacker has involves their packet contents and session information. Many unauthorized data access or modifications propose a successful MITM attack.
- Enable Data Collection for Monitoring and Analysis
- Configure the data collection on the target server and network infrastructure we seizure the impact of intrusion attacks:
- Connection Attempts and Authentication Logs: Follow on login attempts and failed connections for brute-force attacks.
- Packet Throughput: Calculate the throughput on the target server and network we finding the abnormal increases from DDoS or port scanning.
- Error Rates and Response Times: Monitor the server response duration and error rates we permit the impact of SQL injection or MITM attacks.
- Session and Packet Analysis: utilized the data collection we examine the packet details and session logs for finding the unauthorized data access or packet manipulation.
- Run the Simulation
- Start the replication we follow the effects of the intrusion attacks. Let the attacker nodes operates the setting behaviours although legitimate clients handle the regular network traffic.
- Follow on network responses for particularly on the target servers and infrastructure components, below their attack conditions.
- Analyse Results
- Utilize the OPNET’s analysis tools we assign the effects of every intrusion attack on network performance and security:
- Connection Stability and Resource Utilization: Checked the stability of connections besides the CPU and memory consumption on the target server under several kinds of attacker.
- Latency and Response Times: Observe many latencies in server responses for high delay can be specify the overloaded system.
- Error Logs and Authentication Failures: Follow the server logs for unauthorized access attempts, SQL errors, or repeated failed logins from brute-force attacks.
- Packet Capture and Session Data: Intended for MITM attacks evaluation seized and determine the data if complex information was assigned or modify.
- Experiment with Attack Parameters
- Alter the frequency of time and intensity of attacks we validate the several level of affects:
- Aggressive Attacks: configure the high packet frequencies and short inter-arrival duration for rapid and disruptive attacks.
- Stealth Attacks: Utilized the lower frequencies we replicate the secret attacks which are harder to findings.
- Research the targeting several servers through continuously their assigns of how well multi-target attacks are affect the network resilience.
- Implement Countermeasures (Optional)
- Validate the several countermeasures we follow their effectiveness of finding the mitigating of intrusion attacks:
- Intrusion Detection System (IDS): Setting a IDS network we findings the unusual patterns like as high login failure rates or high port scan rates.
- Firewalls and Rate Limiting: Apply the firewall rules and rate-limiting to block the continuous access the attempts for the equal IP address.
- Access Controls and Authentication Lockout: Setting the login attempt limits and account lockouts we avoid the brute-force attacks.
- Encryption (SSL/TLS): Encode the complex data and protect the MITM attacks we assuring the attackers could not easily interpret the interrupted data.
