Cloud computing is known for its capability to deliver on-demand access to a shared pool of configurable computing resources (such as networks, servers, storage, applications, and services) over the internet. This model allows users to quickly scale resources up or down based on demand, pay only for what they use, and access applications and data … Read more
Techniques of QoS encompass various methods used to prioritize and manage network traffic to ensure reliable performance for critical applications. One key technique is Traffic Classification, which categorizes packets based on criteria like source/destination IP addresses, protocols, or application types. This allows network devices to distinguish between different types of traffic and apply appropriate QoS … Read more
Network service model refers to the framework that defines how network services are provided to users and applications. It specifies the characteristics and capabilities of the services offered by the network, such as reliability, security, and performance guarantees. Common network service models include connection-oriented (e.g., TCP) and connectionless (e.g., UDP) protocols, which dictate how data … Read more
Network security process refers to the systematic approach of implementing measures and controls to protect a computer network from unauthorized access, misuse, modification, or denial of service. It involves identifying potential threats and vulnerabilities, implementing preventive and detective measures, monitoring network activities, and responding to security incidents. The process typically includes activities such as risk … Read more
To implement Zero Trust, start by identifying all assets and resources within your network. Next, classify and categorize these assets based on sensitivity and importance. Then, establish strict access controls and policies based on the principle of least privilege, ensuring only necessary access is granted. Implement multi-factor authentication across all systems. Monitor and log all … Read more
The four steps of DHCP (Dynamic Host Configuration Protocol) involve the process of a client obtaining an IP address and other network configuration information from a DHCP server: Discover: In the Discover step, the client broadcasts a DHCP Discover message to find available DHCP servers on the network. This broadcast message is sent to the … Read more
MAC (Media Access Control) access control offers several advantages in network security by restricting access based on physical addresses of devices: Enhanced Network Security: MAC access control prevents unauthorized devices from connecting to the network, reducing the risk of network attacks and unauthorized access to sensitive information. Device Authentication: It allows administrators to authenticate devices … Read more
Network security encompasses measures and practices designed to protect the integrity, confidentiality, and availability of data and resources within a computer network. It involves safeguarding network infrastructure, devices, and data from unauthorized access, attacks, and vulnerabilities. Network security aims to prevent unauthorized users or malicious entities from compromising network resources, stealing sensitive information, disrupting network … Read more
In cloud computing, a hotfix refers to a software update or patch that is applied to fix a critical issue or vulnerability in an application, service, or infrastructure component hosted in the cloud. Hotfixes are typically deployed urgently to address specific problems that could impact system stability, security, or performance. Unlike regular updates or patches, … Read more
The four steps of DHCP (Dynamic Host Configuration Protocol) involve the process by which a client device obtains an IP address and other network configuration parameters from a DHCP server. These steps are: 1. Discover: The client broadcasts a DHCP Discover message on the network to find available DHCP servers. 2. Offer: DHCP servers respond … Read more
