Network Basics: The definition of networks, network types (local area network, wide area network, metropolitan area network) and network topologies (star, bus, ring, mesh).
Network hardware: This section describes network devices, such as routers, switches, servers, and workstations.
Network protocols and services: Describes protocols such as TCP/IP, HTTP, FTP, and DNS, as well as network services such as email and file sharing.
Network architecture: Discusses client-server architecture, peer-to-peer architecture, and cloud computing.
Cyber Security Overview: The importance of cyber security, the types of cyber attacks (e.g., denial of service, man-in-the-middle), and the consequences of security breaches.
Encryption technology: An explanation of encryption principles, encryption types (symmetric and asymmetric), and common encryption algorithms (such as AES, RSA).
Firewalls and Intrusion Detection/Prevention Systems (IDS/IPS): discusses the configuration and functionality of firewalls, as well as IDS/IPS technologies.
Security Protocols and standards: An introduction to secure communication protocols, such as SSL/TLS, and security standards, such as ISO 27001.
Physical security: Precautions for physically protecting network infrastructure, including data centers and server rooms.
Cybersecurity Best Practices: Guidelines for implementing and maintaining a secure network, including regular updates, patches, and employee training.
Networking concepts involve understanding how devices communicate over a network, including the protocols and technologies that enable data exchange. Secure networks involve implementing measures to protect the network and its data from unauthorized access, threats, and attacks. This includes using encryption, firewalls, secure protocols like HTTPS, and network access controls to ensure the confidentiality, integrity, and availability of data transmitted over the network and the following are some key components of secure networks:
1、Firewalls: Firewalls are security devices or software applications that monitor and control incoming and outgoing network traffic based on predefined security rules.
2、Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS): IDS and IPS are security mechanisms that monitor network traffic for suspicious patterns or anomalies and take proactive measures to detect and prevent unauthorized access and malicious activities.
3、Virtual Private Networks (VPNs): VPNs provide secure remote access to private networks over public networks like the internet.
4、Encryption: Encryption is the process of encoding data into a secure format to prevent unauthorized access and protect sensitive information from eavesdropping or tampering.
5、Access Control: Access control mechanisms enforce authentication and authorization policies to regulate user access to network resources and sensitive information.
