Network Security

Securing information and systems is crucial in today’s digital world, where sophisticated cyber threats frequently target individuals and organizations. This paper examines key vulnerabilities in Distributed Denial of Service (DDoS) attacks, phishing, and password security, alongside strategies for defense.

Ping commands, while useful for network diagnostics, are exploited in DDoS attacks, where overwhelming traffic renders networks inaccessible. Network systems are vulnerable due to their capacity limits, which attackers leverage with excessive requests. Symptoms of DDoS attacks include slowed network performance and unavailability of services. Machine learning tools such as Random Forest (RF) are highly effective for early DDoS detection, enabling timely defenses Becerra-Suarez et al, (2024). Configuring firewalls to filter ICMP requests and setting rate limits are additional protective measures.

Phishing attacks exploit human vulnerability by using deceptive emails and messages to trick users into revealing sensitive data. This risk has grown post-COVID, with expanded digital reliance creating new opportunities for attackers. Symptoms include unauthorized transactions and compromised accounts, often resulting in data breaches. Goenka, Chawla, and Tiwari (2024) suggest that adaptive email filtering and user training can help mitigate these risks by enabling users to recognize and avoid phishing attempts. 

Password cracking, another widespread threat, occurs when weak or reused passwords enable attackers to gain access to systems. Once inside, attackers can extract sensitive information, potentially causing privacy violations and financial losses. According to Vahid and Lysecky (2019), strategies like enforcing complex passwords and enabling multi-factor authentication (MFA) provide essential layers of protection. Additionally, avoiding password storage on shared devices and regularly updating passwords can help maintain account security.

These insights demonstrate the importance of proactive security measures. Using machine learning for DDoS detection, educating users on phishing risks, and enforcing strong password policies are essential steps in safeguarding digital environments from evolving threats.
