1.1 Introduction to Network Security Flashcards
What is Network Security?
A set of measures and applications used to protect computer networks from unauthorized access, abuse, interruption, or changes.
What are firewalls used for in network security?
To regulate and screen incoming and outgoing network traffic, block potential threats, and prevent unauthorized access.
What is Access Control and Authentication?
Methods to verify identities of users and devices, including username/password and multi-factor authentication (MFA).
Why is encryption important in network security?
It ensures data remains secure and inaccessible to unauthorized individuals, protecting sensitive information during transmission or storage.
What is network segmentation?
The logical division of a network into distinct segments to isolate traffic and narrow down the potential attack surface.
What are Intrusion Detection and Prevention Systems (IDPS)?
Systems that monitor network traffic to detect and block attacks by identifying known attack types and abnormal traffic patterns.
What is the role of Patch/Update Management in network security?
To address known security vulnerabilities by keeping systems and software up-to-date with regular security patches.
Why is network monitoring and logging important?
To detect and respond to security threats by analyzing network logs for abnormal activities or attacks.
What does physical security mean in the context of network security?
Protecting physical access points such as server rooms, network devices, and data centers.
Why is education and awareness important for network security?
To encourage practices like strong password use, identifying phishing emails, and adhering to security policies.
