Ethical Hacking - Red Team vs Blue Team.pptx

This presentation is about Red Team vs Blue Team in the world of Cyber Security and how they would perform in Real World attack scenarios.

1. Red Team vs. Blue Team Exercises: Simulating Real-World Attack Scenarios Presented By: Aayush Dutta (21/CSE-CS/001) Urooj Ahmed (21/CSE-CS/061)

2. RED TEAM & BLUE TEAM Red Team vs. Blue Team

3. THE TEAMS Red Team Offensive security experts who simulate real-world attacks to identify and exploit vulnerabilities Test and evaluate the effectiveness of the organization's defenses Conduct penetration testing, social engineering, physical security assessments, and exploitation of vulnerabilities Blue Team Defensive security professionals who protect and monitor the organization's assets. Objective is to detect, respond to, and mitigate security threats to maintain the integrity and availability of systems. Activities include security monitoring, incident response, threat hunting, and vulnerability management.

4. The Role of Purple Team in Cybersecurity Exercises Purple Team is a collaborative group that bridges the gap between Red and Blue Teams to enhance overall security effectiveness. The objective of Purple Team is to facilitate continuous feedback and learning between offensive and defensive teams. Activities of Purple Team include joint exercises and workshops, sharing insights and tactics, and improving communication and coordination.

5. Key Differences Red Team vs. Blue Team

6. RED TEAM BLUE TEAM FOCUS Attacking Defending GOAL Identify vulnerabilities Protect and secure assets APPROACH Offensive tactics and techniques Defensive measures and monitoring

7. Red Team Tools Nmap: Network scanning tool for discovering hosts and services. Recon-ng: Web reconnaissance framework for gathering open-source intelligence. Shodan: Search engine for finding vulnerable Internet-connected devices. Nessus: Comprehensive vulnerability scanner for identifying vulnerabilities, misconfigurations, and malware. Metasploit Framework: Platform for finding, exploiting, and validating vulnerabilities. BeEF : Tool focusing on web browser security assessments. SQLmap : Automates detecting and exploiting SQL injection flaws. Empire: Framework with modules for privilege escalation, credential dumping, and persistence. Cobalt Strike: Suite for adversary simulations with post-exploitation tools and payloads.

8. Blue Team Tools SIEM: Splunk, ArcSight, LogRhythm EDR: Carbon Black, SentinelOne NSM: Zeek, Suricata Threat Intelligence: MISP Incident Response: TheHive SOAR: Phantom Log Management: Graylog Packet Capture and Analysis: Wireshark Threat Hunting: Splunk Enterprise Security Deception Technology: TrapX, Cymmetria

9. Phases of a Red Team Exercise Reconnaissance: Gathering information about the target Enumeration: Identifying potential entry points Exploitation: Gaining access by exploiting vulnerabilities Privilege Escalation: Increasing access within the system Lateral Movement: Moving within the network to achieve objectives Persistence: Maintaining access for future exploitation Data Exfiltration: Extracting valuable data

10. Phases of a Blue Team Exercise Establish baseline security measures through Preparation. Monitor for suspicious activity through Detection. React to detected threats through Response. Limit the spread of the threat through Containment. Remove the threat from the environment through Eradication. Restore systems to normal operation through Recovery. Analyze the incident to improve defenses through Lessons Learned.

11. Red Team vs. Blue Team Scenarios Simulated Phishing Attack Red Team: Craft and send phishing emails Blue Team: Detect and respond to phishing attempts

12. Red Team vs. Blue Team Scenarios Simulated Phishing Attack Red Team: Craft and send phishing emails Blue Team: Detect and respond to phishing attempts

13. Network Intrusion Red Team: Breaching the network perimeter Blue Team: Detecting, isolating, and mitigating the intrusion

14. Physical Security Breach Red team attempts unauthorized physical access to the facility Blue team monitors physical security alerts and responds to the breach

15. Case Study: Simulated Attack Scenario Red Team simulates a ransomware attack

16. Red Team Actions 1. Reconnaissance: - Tool: Maltego - Action: Gather open-source intelligence (OSINT) on TechCorp , including employee details, email addresses, and publicly available network information. 2. Initial Access: - Tool: Phishing toolkit (e.g., Gophish ) - Action: Launch a spear-phishing campaign targeting TechCorp employees, aiming to trick a user into clicking a malicious link or downloading a malware-infected attachment.

17. Red Team Actions 3. Execution: - Tool: Metasploit Framework - Action: Exploit vulnerabilities in the target system to establish a foothold. For instance, using a known vulnerability in the company's web server software to gain initial access. 4. Persistence: - Tool: Cobalt Strike - Action: Deploy a beacon to maintain a persistent presence on the compromised systems, allowing for ongoing access.

18. Red Team Actions 5. Privilege Escalation: - Tool: PowerSploit - Action: Use privilege escalation exploits to gain higher-level permissions on the compromised system. 6.Lateral Movement: - Tool: BloodHound - Action: Map out the Active Directory structure to identify potential pathways to move laterally across the network towards the target database server. 7. Data Exfiltration: - Tool: Rclone - Action: Transfer sensitive data from the database server to an external server controlled by the Red Team, using encrypted channels to avoid detection.

19. Blue Team Actions   1. Preparation and Identification: - Tool: Splunk (SIEM) - Action: Set up monitoring and alerting for suspicious activities like unusual login patterns, high data transfer rates, and execution of unfamiliar processes. 2. Protection: - Tool: CrowdStrike Falcon (EDR) - Action: Implement endpoint detection and response solutions across all endpoints to detect and block known malware and exploit attempts. 3. Detection: - Tool: Wireshark - Action: Analyze network traffic to detect anomalies such as large outbound data transfers or communications with known malicious IP addresses.

20. Blue Team Actions   4. Response: - Tool: Cortex XSOAR (SOAR) - Action: Automate incident response playbooks to quickly isolate affected systems, contain the breach, and notify the incident response team. 5. Mitigation: - Tool: Carbon Black Response - Action: Investigate and remediate compromised systems by terminating malicious processes, removing persistence mechanisms, and applying patches to prevent further exploitation. 6. Recovery: - Tool: Veeam (Backup and Replication) - Action: Restore affected systems and databases from clean backups to ensure business continuity and integrity of data.

21. Conclusion Red Team vs. Blue Team exercises are crucial for robust cybersecurity. These exercises provide valuable insights. They improve overall security resilience.
