Cybersecurity Threats & Prevention Presented by Vrushank Mehra | Roll No. 23BIT215
Why Cybersecurity Matters in 2025 $10.5 Trillion Projected annual cybercrime damages globally by 2025 Every 11 Seconds A ransomware attack strikes a business worldwide Universal Targets Cyber threats affect individuals, enterprises, and critical infrastructure
Understanding Cybersecurity Threats What Are Cyber Threats? Malicious activities designed to steal, disrupt, or damage sensitive data and computer systems. These threats operate at multiple levels, from individual account compromise to large-scale infrastructure attacks. Who Are the Attackers? Cybercriminals seeking financial gain Nation-states conducting espionage Malicious insiders abusing privileges Hacktivists pursuing ideological goals
Top Cyber Threats Today Malware Viruses, worms, Trojans, spyware, cryptojacking, and fileless malware designed to infiltrate and compromise systems silently. Ransomware Encrypts critical data and demands ransom payments, often in untraceable cryptocurrency, causing operational paralysis. Phishing & Social Engineering Deceptive emails, messages, and pretexting tactics designed to manipulate users into revealing credentials or sensitive information. DDoS Attacks Distributed Denial of Service attacks overwhelm servers with traffic, rendering services unavailable to legitimate users. Insider Threats Employees or contractors exploiting trusted access to steal data, sabotage systems, or compromise security from within.
Case Study: The 2024 Ransomware Surge 1 60% Increase in Attacks Healthcare and financial sectors faced unprecedented ransomware campaigns, compromising patient records and financial systems. 2 Colonial Pipeline Attack A critical infrastructure attack caused nationwide fuel shortages and resulted in a $4.4 million ransom payment, demonstrating real-world impact. 3 Key Lessons Learned The importance of offline tested backups and comprehensive incident response plans in mitigating ransomware damage and recovery time.
How Threat Prevention Works Proactive Detection Identify and block attacks before they cause damage through continuous monitoring and threat intelligence. Multi-Layer Defence Deploy firewalls, antivirus software, intrusion prevention systems, and real-time threat analysis across all systems. Vulnerability Management Apply patches promptly and manage security configurations to eliminate exploitable weaknesses attackers target. Access Limitation Restrict attacker lateral movement through segmentation and principle of least privilege, containing breach impact.
Best Practices for Prevention Regular Patching Apply security updates immediately to block known exploits and close vulnerability windows before attackers act. Strong Authentication Implement multi-factor authentication (MFA) everywhere to prevent unauthorised access even when credentials are compromised. Employee Training Regular cybersecurity awareness programmes significantly reduce phishing success rates and insider threat incidents. Offline Backups Maintain tested, offline backups to ensure business continuity and rapid recovery from ransomware attacks. Network Segmentation Isolate critical systems to limit attacker lateral movement and contain breach scope effectively.
Emerging Technologies in Cybersecurity AI-Powered Detection Machine learning algorithms identify threats faster than humans, detecting anomalies and responding automatically to evolving attack patterns. Zero Trust Architecture "Never trust, always verify"—continuous authentication and authorisation across all network access, regardless of location or device. Behavioural Analytics Monitor user behaviour patterns to detect insider threats, account compromise, and anomalous activities in real time. Cloud Security Innovation Advanced security solutions protect hybrid environments, ensuring consistent protection across on-premises and cloud infrastructure.
What To Do When Things Go Wrong 1 Detect & Alert Identify the breach quickly through monitoring systems and activate your incident response team immediately. 2 Contain the Threat Isolate affected systems to prevent further spread and preserve evidence for investigation and forensic analysis. 3 Eradicate the Attack Remove malware, close vulnerabilities, and reset compromised credentials to eliminate attacker presence completely. 4 Recover & Report Restore systems, notify authorities and stakeholders promptly as required by law, and conduct thorough post-incident analysis.
Conclusion: Stay Vigilant, Stay Prepared Cyber threats evolve constantly. Prevention demands continuous effort, investment, and vigilance across technology, people, and processes. Defence Strategy Combine technology controls, comprehensive training programmes, and robust security policies for effective protection. Your Role Cybersecurity is everyone's responsibility. Awareness and immediate action protect data, systems, and organisational trust. Stay Alert Report suspicious activity, follow security protocols, and engage continuously with cybersecurity initiatives. Thank you! Questions?
