1. Presented By Md. Saiful Islam (221-15-5463) Md. Abu Sayed(221-15-5908) Nazmul Huda Badhon(221-15-4772) Md. Abrar Awal Prochod(221-15-5912) Tomal Ahmed Sajib (221-15-5406) Presentation on Smart Home Security Breach Presented to Md. Moniruzzaman Hemal Lecturer, Dept of CSE Daffodil International University

2. Introduction to Smart Home Security Breach What is a Smart Home? A smart home uses internet-connected devices to enable remote management and automation of home systems such as lighting, heating, security, and appliances. What is a Security Breach? A security breach is unauthorized access to a system, network, or device, often leading to data theft, privacy invasion, or system compromise.

3. Problem Identification Interconnectivity Creates Vulnerabilities. Lack of Standard Security Measures. User Awareness is Low. Consequences are Serious:- Unauthorized surveillance- Break-ins via compromised smart locks- Identity theft from exposed data- Loss of trust in smart technologies

4. Why This Problem Why This Matters? As smart homes become more common, they become more attractive targets for cybercriminals.

5. How Did the Hacker Get In? In this smart home case, the hacker used a cyberattack to break into the system. The most possible attack was- Credential Theft The hacker guessed or stole the password. Man-in-the-Middle The hacker secretly watched the app’s messages and entered.

6. Attack Method Intercepted app-to-device communication (unsecured Wi-Fi or cloud server vulnerability). Used default or weak passwords (common issue in smart home devices). Possibly used phishing to gain user login data. Why This Attack Worked? Lack of multi-factor authentication (MFA). No encryption on data transmission between mobile app and home system Devices had minimal built-in security settings.

7. Real Life Examples Ring Camera Hack (USA, 2019) Hackers got into Ring home cameras by using old or stolen passwords. They talked to family members and scared them through the speaker. Nest Thermostat Hack (USA, 2018) A hacker used a reused password to log into a family’s Nest account and kept changing the temperature again and again. Mirai Botnet Attack (Worldwide, 2016) Hackers used default passwords to break into thousands of smart devices. They used these devices to attack major websites in a large cyberattack.

8. Cyberattack on Smart Homes: An Impact Analysis Explore how a recent cyberattack compromised the fundamental security principles of a smart home: Confidentiality, Integrity, and Availability. Presented by: Nazmul Huda Badhon ID: 221-15-4772

9. Breaching the CIA Triad Confidentiality Unauthorized access to live security camera feeds and stored footage, compromising residents' privacy and daily routines. Integrity Remote manipulation of smart door locks, demonstrating unauthorized tampering with system commands and unintended device behavior. Availability Disruption or disablement of critical camera systems, rendering essential security devices inoperable during crucial moments.

10. Key Takeaways & Next Steps Attack Implications Privacy violations through data exposure. Operational disruption from system tampering. Loss of critical security functionality. Strengthening Defenses Implement robust encryption for all data streams. Enhance authentication protocols for remote access. Establish redundant systems for critical functions. This incident highlights the interconnectedness of the CIA triad and the need for a holistic security approach in smart home ecosystems.

11. IoT Security Challenges in Smart Homes Delve into the inherent vulnerabilities of smart home ecosystems, exploring how specific Internet of Things (IoT) characteristics contribute to significant security risks. Understanding these challenges is crucial for developing robust defense mechanisms in an increasingly connected world.

12. Common Vulnerabilities in Smart Home Devices Weak Authentication Many IoT devices come with easily guessable default passwords or allow users to set simple, weak credentials, creating immediate entry points for attackers. This oversight is a primary target for automated hacking attempts. Unencrypted Communications Data exchanged between smart home apps and devices often lacks proper encryption, making it susceptible to interception. Sensitive information, like door lock commands or camera feeds, can be read or manipulated by malicious actors. Infrequent Firmware Updates Manufacturers frequently neglect to provide timely security updates for IoT devices, leaving known vulnerabilities unpatched. This creates a widening window of opportunity for attackers to exploit flaws over time.

13. Common IoT Security Weaknesses in a Smart Home System This diagram highlights common vulnerabilities across a typical smart home setup, from individual devices to the overarching network. Each weak point represents a potential entry for malicious actors, underscoring the need for comprehensive security measures.This diagram highlights common vulnerabilities across a typical smart home setup, from individual devices to the overarching network.

14. Systemic Security Gaps Absence of Built-in Protections Unlike computers, most IoT devices lack integrated antivirus software or firewalls. This leaves them exposed to direct malware attacks and unauthorized network access, turning individual devices into weak links.

15. Lack of Standardized Security The IoT landscape is fragmented, with numerous brands operating on diverse platforms and protocols. This absence of unified security standards makes it challenging to implement comprehensive protection across an entire smart home system.

16. Scenario: Smart Home Security Breach Imagine a typical evening. You control your home's lights, temperature, and security through a smart home system . But one night, a hacker exploits a vulnerability in your smart lock, gains unauthorized access, disables the security cameras, and enters your home. This scenario highlights the real risks of smart home devices.

17. Understanding the Risks of Smart Home Devices Smart Locks : Vulnerable to hacking, especially if default passwords are not changed. Smart Cameras : Can be compromised, allowing hackers to spy on your home. Smart Lights : May be used as entry points to access your entire network. These devices often have weak security protocols, making them easy targets for cyberattacks.

18. Recommended Security Solutions Strong Passwords : Use unique, complex passwords for each device and your network. Regular Software Updates : Keep all devices updated to patch known vulnerabilities. Security Patches : Install security patches promptly to protect against exploits.

19. Network Security Best Practices Firewalls : Use a firewall to monitor and control incoming and outgoing network traffic. Network Segmentation : Segregate your smart home network from personal devices to limit exposure. Guest Networks : Use a guest network for visitors to prevent them from accessing your main network.

20. Secure Device Configuration Disable Unnecessary Features : Turn off features you don't use to reduce attack surfaces. Change Default Settings : Always change default usernames and passwords to prevent easy access. Two-Factor Authentication : Enable two-factor authentication for an extra layer of security.

21. Machine Learning (ML) ML can be used for threat detection , identifying unusual patterns in network traffic . Deep Learning (DL) DL enables anomaly detection , spotting deviations from normal device behavior . Blockchain Blockchain can secure data transactions , ensuring data integrity and preventing tampering . Future Trends in Smart Home Security

22. Conclusion: Proactive Security Measures Securing your smart home requires vigilance and proactive measures . By adopting strong passwords, keeping devices updated, and implementing network security best practices, you can protect your home from potential breaches. Embrace new technologies like ML, DL, and blockchain to enhance your security posture.
