Study Notes
Cybersecurity Threats
- Cybersecurity threats are constantly evolving and present a challenge to individuals and organizations.
Understanding the Threat Landscape
- Advanced Persistent Threats (APTs) are sophisticated and persistent cyberattacks targeting specific organizations.
- Malware is malicious software designed to damage, steal or gain unauthorized access to computer systems.
- Phishing is a deceptive attempt to trick users into revealing sensitive information or granting access to their devices.
- Denial-of-Service (DoS) Attacks overwhelm a target system with traffic, preventing legitimate users from accessing services.
Common Cyberattack Vectors
- Email: Phishing emails are a common method for delivering malware or stealing credentials.
- Websites: Compromised websites can host malware or redirect users to malicious sites.
- Mobile Devices: Malicious apps, SMS phishing, and insecure Wi-Fi networks pose risks to mobile devices.
Social Engineering Tactics
- Pretexting: Creating a believable scenario to gain access to information.
- Baiting: Offering something enticing to lure victims into a trap.
- Scare Tactics: Using fear to manipulate users into making hasty decisions.
- Authority: Posing as someone with authority to gain trust and access.
Ransomware and its Impact
- Infection: Ransomware infiltrates a system through various methods.
- Encryption: Ransomware encrypts files, making them inaccessible.
- Demand: Attackers demand payment in exchange for decryption keys.
- Impact: Disruptions to operations, data loss, and financial losses.
IoT Security Challenges
- Default Credentials: Many IoT devices ship with weak or default passwords, making them easy to exploit.
- Lack of Updates: Security vulnerabilities may not be patched, leaving devices open to attacks.
- Data Privacy: IoT devices collect personal data, raising concerns about privacy and security.
