Here are some examples of how the command prompt looks for the 3 major operating systems:. A distributed denial of service is a malicious attempt to disrupt normal traffic of a service, a server, or a network by overwhelming the infrastructure with a flood of fake traffic. In other words, a DDoS attack tries to create a traffic jam on the route to prevent genuine traffic from reaching your service, server, or network. DDoS attacks are initiated by flooding the bandwidth or resources of a target system.
Such attacks are effective as they utilize a network of compromised computers or IoT Internet of Things devices as a source of attack traffic. The attackers gain control over a large number of computers or IoT devices by infecting them with malware , and then use the infected devices as a botnet to launch their attacks. File transfer protocol is a network protocol used for transferring files between a client and a server on a computer network.
For example, if you want to install WordPress on your webserver to host your website, you will have to use FTP to copy your files to the server. Although it is less common nowadays as most companies use the cloud, some businesses still use FTP to share files. Companies that prefer to keep the files hosted on their on-premises server, use FTP to share files stored on their server.
Employees upload files to their FTP server and share links to those files with their colleagues, similar to how you would share a file on Google Drive.
It is a set of rules for the routing and addressing of data so that they can travel across networks and reach the correct destination. When traveling across a network such as the Internet, data is divided into small pieces called packets. Attached to each packet is the IP information, which helps the routers send those packets of data to the right address.
Each device or domain connected to the internet has a unique IP address and the packets are directed to the correct IP addresses using the IP information. An internet service provider is an organization that provides you with access to the internet. To connect your device such as a laptop to the internet, you need special networking, telecommunications, and routing equipment. ISPs make Internet access possible by routing Internet traffic, resolving domain names, and maintaining the network infrastructure.
A local area network is a computer network that interconnects devices within a limited physical location, such as an office or home. It can be large such as an enterprise network with thousands of users and devices or small such as a home network with one user.
A typical office LAN is made up of cables, APs, switches, routers, and other components, which enable the devices to connect to internal servers and other LANs. A LAN allows the connected devices to use a single internet connection, use shared printers, share files, and even access the connected devices. A mobile device management software is a type of security and management software that allows IT administrators to monitor, manage, and secure business or personal mobile devices.
An MDM application is an excellent security tool and is greatly appreciated by any system administrator because it provides a unified platform for managing all the different devices across the organization. It gives the IT admin remote access to all company devices, on which the MDM is installed, and allows them to deploy security patches, configure settings, update operating systems and applications. Additionally, they can even allow the admins to remotely wipe the data on the devices in case they are lost or stolen.
Multi-Factor Authentication is a security system, which requires a user to provide multiple types of credentials to verify their identity.
