A host-based firewall system is an essential component of any network’s security infrastructure. It acts as a policy-based traffic filter, allowing or blocking access to and from a host based on predefined rules. Unlike a network-based firewall that protects an entire network, a host-based firewall is installed on individual devices, providing a higher level of ...
A Virtual Private Interconnect (VPI) is a service that allows for the secure connection of two or more networks over a shared infrastructure. It operates at the network layer and works by encapsulating packets within a specific protocol, such as ATM (Asynchronous Transfer Mode). When a packet is sent across a network, it contains a ...
The growing amount of data exchanged over the internet has made it imperative for organizations to prioritize the monitoring and prevention of security breaches. Intrusion detection systems (IDS) play a vital role in protecting networks and hosts from unauthorized access and malicious activities. Host-based intrusion detection systems (HIDS) focus on analyzing and monitoring activities within ...
Nowadays, malicious attacks and security incidents have become a major concern for individuals and organizations. To strengthen their defense against these threats, advanced technologies and software have been developed, and one such technology is Host Intrusion Detection Systems (HIDS). HIDS is a security software that monitors and analyzes the activity of a host or a ...
A Layer 1 switch, also known as a network switch or simply a switch, is a device that enables the connection and transfer of data between multiple devices in a network. Unlike Layer 2 and Layer 3 switches, which operate at higher layers of the network protocol, a Layer 1 switch operates at the physical ...
A bastion host is a dedicated and highly secure server or gateway that is used to authenticate, authorize, and control access to a private network from an external network, such as the internet. It acts as a point of defence and protection for the internal network, filtering and managing traffic to ensure only authorized and ...
Snort is a powerful and widely-used tool in the world of network security. It is an open-source software that serves as an Intrusion Detection System (IDS) and Intrusion Prevention System (IPS). With Snort, network administrators can monitor network traffic for potential security breaches and take appropriate actions to protect their systems. Snort works by analyzing ...
A modem is an essential device for connecting to the internet through an Internet Service Provider (ISP). However, its functionality goes beyond just providing an internet connection. A modem can also function as a bridge, connecting multiple devices to a network. Furthermore, a modem can act as a server, allowing devices on a network to ...
The Advantages of VLANs: How Virtual LANs Benefit Your Network The implementation of Virtual LANs (VLANs) in a network brings numerous benefits, including scalability, redundancy, management, flexibility, security, isolation, and reliability. VLANs allow for the partitioning of a physical network into multiple virtual networks, each with its own set of broadcast traffic and configuration settings. ...
Networking plays a crucial role in the modern world, connecting devices and facilitating communication across networks. Whether you’re a seasoned network engineer or just starting out, having a strong understanding of essential networking concepts is vital to getting ahead in this field. One fundamental aspect of networking is understanding IP addresses and how they are ...
