What is Alias/Secondary IP Address?IP aliasing is the process of assigning several IP addresses to a network interface. It allows a single node on a network to have many network connections, each having a different purpose.Multiple network addresses can be provided on a single physical interface using IP aliasing. One rationale for doing so could be to make a single computer appear to be several computers.How to configure?In Linux, to use IP aliasing, the Kernel must be compiled with network aliasing and IP options. Then the aliases would attach to the virtual network device or interface with a specific virtual ... Read More

What is RDMA?The access of one computer's memory by another in a network without the involvement of any computer's operating system, processor, or cache is referred to as RDMA. Because many resources are freed up, it aids in improving system throughput and performance.On a remote machine, read and write operations can be performed without being interrupted by the CPU of that machine. The data transfer rate is increased, and networking latency is reduced, thanks to this technology. It uses zero-copy networking for transferring data directly into system buffers by enabling network adapters.RDMA was earlier used only in high-performance computing (HPC) ... Read More

Inter-Switch LinkISL is a VLAN protocol that stands for Inter-Switch Link. Cisco's ISL is a proprietary protocol that is only utilized between Cisco switches.A point-to-point VLAN context can support up to 1000 VLANs and is only compatible with Fast Ethernet and Gigabit Ethernet networks.ISL encapsulates an Ethernet frame with a header that sends VLAN IDs between switches and routers. The tag in IEEE 802.1Q is internal.An Ethernet encapsulated ISL frame will typically start at 94 bytes and grow to 1548 bytes in size. Encapsulation is used to develop the protocol.The frame is given a 26-byte header and a 4-byte CRC ... Read More

What is a Denial-of-Service Attack?A Denial-of-Service (DoS) attack is an attack on a computer network that limits, restricts, or stops authorized users from accessing system resources.DoS attacks work by flooding the target with traffic or sending it data that causes it to crash. It deprives genuine users of the service or resources they expect to receive.DoS assaults frequently target high-profile corporations such as banks, commerce, media companies, and government and trade organizations' web servers.Even through DoS assaults seldom result in the theft or loss of critical information or other assets, they can take a lot of time and money to ...

TCP stands for Transmission Control Protocol and IP stands for Internet Protocol. TCP/IP is a suite of protocols used for the communication of devices on a network. The network can be of any type: Internet or personal networks like the intranet, extranet, etc.The modern developments that we use on the Internet are only possible because of the TCP/IP suite. Although the name suggests only two protocols, it contains other protocols in it. Let us look at the functioning of this suite in detail.Working of TCP/IPIn simple terms, TCP takes care of how data is transferred in a network.It breaks down ... Read More

The United States military is considered to be one of the most sophisticated forces in the world. However, it was challenged and called into question by a 2019 attack on one of the United States' naval stations.Ryuk RansomwareThe US Coast Guard's Christmas 2019 celebrations were apparently ruined by a Ryuk Ransomware assault, which purportedly interrupted government agencies' activities for more than 33 hours. A risk management program was created in accordance with the security protocol, following the best practices outlined in the NIST Cybersecurity Framework (CSF) and NIST Special Publication 800-82.This is a form of ransomware assault that may have ...

Datalink is a layer in the Open System Interconnections. It is the second layer in between the physical layer and the network layer. It manages the connection between the two nodes. Data links integrate certain methods like error control, flow control, and associated link management functions.Some of the main functions of the data link layer include providing a straightforward service interface to the network layer, framing flow control and error recognition, and frame formatting.Types of Data Link LayersData Link layer is mainly of two types −Logical Link Control Sub-Layer (LLC)Media Access Control Sub-layer (MAC)Logical Link Control Sub-Layer (LLC)It gives logic for ...
