Bullet Points:

To provide a better understanding of the topics covered, we have included some sample bullet points for each section.

1. Network Security
   Network security is the practice of protecting networks from unauthorized access or attacks.
   The essential elements of network security are confidentiality, integrity, and availability.
   A firewall is a network security device that monitors and controls incoming and outgoing traffic based on predetermined security rules.
   An intrusion detection system (IDS) is a device or software application that monitors network traffic for signs of malicious activity.
   A virtual private network (VPN) is a secure and encrypted connection that allows users to access a private network over the internet.
   A distributed denial-of-service (DDoS) attack is a type of attack that aims to disrupt the normal functioning of a website or network by overwhelming it with traffic.
   A man-in-the-middle (MITM) attack is a type of attack where an attacker intercepts communication between two parties to steal information or compromise the network.2. System Security
   System security refers to the practice of protecting individual computer systems from unauthorized access or attacks.
   An access control list (ACL) is a list of permissions that determines which users or systems have access to specific resources.
   A biometric authentication system uses biometric data, such as fingerprints or facial recognition, to authenticate users.
   Symmetric encryption uses the same key to encrypt and decrypt data, while asymmetric encryption uses different keys.
   A security information and event management (SIEM) system is a tool that collects and analyzes security-related data from multiple sources.
