Study Notes
Cybersecurity Concepts
- Hackers: Individuals who illegally breach computer systems and networks, often for malicious purposes.
- Boot-sector viruses: Types of malware that infect the boot sector of USB drives, executing upon system startup.
Network Security Tools and Techniques
- Packet Analyzer (Sniffer): A tool that captures and analyzes data packets as they traverse a network, helping in troubleshooting and monitoring.
- Ransomware as a Service (RaaS): A model that has led to an increase in ransomware attacks by enabling even non-technical users to launch such attacks.
Malicious Software
- Rootkit: A type of malicious software that gives unauthorized users complete control of a computer without detection.
- Inoculation in Antivirus Software: A preventative method where antivirus programs record file attributes to monitor for changes and potential infections.
Authentication and Protection Measures
- Multifactor Authentication: Security protocol that requires verification through a combination of something known (password), something inherent (biometrics), and something owned (security token).
- Biometrics: Authentication methods that use personal biological traits like fingerprints or facial recognition for security.
Device Protection
- Surge Protectors: Devices designed to protect electronic equipment from voltage spikes, ensuring device longevity and preventing damage.
- Network Address Translation (NAT): A firewall technique that assigns internal IP addresses to devices, obscuring them from external threats.
Security Best Practices
- Sharing Personal Information: It is unsafe to share sensitive information like social security numbers online or via email.
- Phishing: A fraudulent technique that involves sending deceptive emails to trick users into divulging personal data.
Misconceptions and Truths
- Port Assignments: It is incorrect to assume that the logical port of a computer is always port 8000; port numbers vary based on application and setting.
- Data Encryption on Mobile Devices: Encrypting data on smartphones is critical for security and protecting personal information.
- VPN Security: Utilization of Virtual Private Networks (VPNs) can make sending information over public networks as secure as private ones.
