Study Notes
Multifactor Authentication
- Combines three elements for security: something you know (like a password), something you are (biometric data), and something you own (like a security token).
Logical Ports
- Misconception: Logical ports are specifically designed for certain cable connectors. This statement is false.
Phishing
- A cyber technique where emails trick recipients into providing personal information.
Firewalls and NAT
- Firewalls utilize Network Address Translation (NAT) to assign IP addresses internally. This helps conceal devices from external hackers.
Social Security Number Privacy
- Important: Never share your Social Security number through websites, emails, or messaging as it can lead to identity theft.
System Backups
- Images or system backups store critical files, including applications, operating systems, and user data.
Rootkits
- A rootkit is a type of malware that allows unauthorized control of a computer unbeknownst to the user.
Boot-Sector Viruses
- These viruses activate from USB drives that remain connected during computer startup, posing significant security risks.
Data Encryption on Mobile Devices
- Contrary to some beliefs, encrypting data on mobile devices like smartphones is a best practice for security.
Hackers
- Individuals who illegally access computers or networks to exploit vulnerabilities.
Ransomware Attacks
- Minimal technical knowledge is required to execute ransomware attacks, as criminals can leverage Ransomware as a Service (RaaS) platforms.
Antivirus Software and Inoculation
- Antivirus programs prevent malware infections by monitoring file attributes and employing a technique referred to as inoculation.
Virtual Private Networks (VPNs)
- VPNs ensure that data transmission over public networks remains as secure as on private networks, safeguarding user information.
Surge Protectors
- A surge protector, appearing like a normal power strip, provides essential protection for devices against voltage spikes.
Packet Analyzers
- Also known as sniffers, packet analyzers capture and decode data packets, monitoring network activity for analysis.
