The paper "Cyber Security Vulnerabilities and Remediation Through Cloud Security Tools" by FNU Jimmy, a senior cloud consultant at Deloitte, USA, explores the growing importance of cyber security in the digital age. With the widespread adoption of digital technologies such as cloud computing, IoT, social media, and cryptocurrencies, traditional crimes have migrated to the digital realm, leading to an increase in cyber attacks. These attacks, including DDoS, phishing, man-in-the-middle, password theft, and malware, are becoming more sophisticated and harder to detect with conventional security measures like firewalls and antivirus software. The paper highlights the need for innovative solutions to combat these threats, emphasizing the potential of cutting-edge technologies such as machine learning, deep learning, cloud platforms, big data analytics, and blockchain. These technologies can enhance malware detection, intrusion detection, spam filtering, DNS attack classification, fraud detection, and the identification of covert channels and advanced persistent threats. However, the paper also notes that some of these solutions, particularly machine learning and deep learning, are susceptible to evasion techniques, requiring careful consideration in defense strategies. The introduction provides a historical context of cyber crime, tracing its evolution from phone phreaking in the 1950s to the sophisticated attacks of the 21st century. It discusses the impact of the COVID-19 pandemic on digital transformation and the resulting increase in cyber attacks. The paper then delves into the fundamental principles of cyber security, including confidentiality, integrity, and availability (CIA), and explores various types of cyber threats such as viruses, worms, Trojans, and rootkits. The paper also examines the causes of cyber attacks, including system errors, network protocol vulnerabilities, and the proliferation of emerging technologies like smartphones, IoT devices, and cloud computing. It highlights the challenges in securing critical infrastructure systems and the role of knowledge in the rise of cyber attacks. Finally, the paper provides a comprehensive overview of common cyber threats, such as spyware, scareware, joke programs, ransomware, and remote access tools, along with recommendations for mitigating these risks. It emphasizes the importance of user education, robust security measures, and continuous vigilance in the face of evolving cyber threats.The paper "Cyber Security Vulnerabilities and Remediation Through Cloud Security Tools" by FNU Jimmy, a senior cloud consultant at Deloitte, USA, explores the growing importance of cyber security in the digital age.
