Basics of Network Security Flashcards
What is the significance of network security in cybersecurity?
Network security protects the integrity, confidentiality, and availability of networks, preventing unauthorized access and ensuring secure data transmission.
What is multi-factor authentication and why is it important?
Multi-factor authentication requires users to provide multiple forms of evidence (e.g., password and fingerprint) to enhance security and prevent unauthorized access.
How do firewalls contribute to network security?
Firewalls monitor and control incoming and outgoing network traffic based on security rules, acting as a barrier between trusted and untrusted networks.
What are common forms of malware?
Common forms of malware include viruses, worms, trojans, and ransomware.
Why are strong passwords and regular updates important?
They prevent attackers from exploiting weak or default passwords, reducing unauthorized access risks.
What is the role of encryption in network security?
Encryption converts data into an unreadable format (ciphertext) to protect it from unauthorized access during transmission or storage.
How does network monitoring help in cybersecurity?
Network monitoring involves observing network traffic to identify unusual patterns or activities that may indicate security threats.
What are intrusion detection systems (IDS)?
IDS are systems that analyze network traffic to detect and alert on potential security breaches using attack signatures or behavior patterns.
What are best practices for securing wireless networks?
Best practices include changing default router credentials, updating firmware, and enabling encryption protocols like WPA2.
Why is network security more important than ever?
The growth of technology and interconnected devices has increased vulnerabilities to threats like unauthorized access and data breaches.
What are access controls in network security?
Access controls are mechanisms that limit who can access resources or perform actions, protecting data and systems from unauthorized use.
What is the function of a virtual private network (VPN)?
A VPN secures data transmission by creating an encrypted tunnel between devices, protecting it from interception.
How can organizations protect against malware?
Organizations can protect against malware by using antivirus software, educating users, and implementing email and web filtering.
What is the significance of firmware updates for network security?
Firmware updates address security vulnerabilities and improve the overall security of network devices.
