Topics available for training include cyber and network defenses, penetration testing, incident response, digital ...
An example of a physical security measure: a metal lock on the back of a personal computer to prevent hardware tampering. Computer security (also cybersecurity, digital security, or information technology (IT) security) is the protection of computer software, systems and networks from threats that may result in unauthorized information disclosure, theft of (or damage to) hardware, software, or ...
In computer networking, promiscuous mode is a mode for a wired network interface controller (NIC) or wireless network interface controller (WNIC) that causes the controller to pass all traffic it receives to the central processing unit (CPU) rather than passing only the frames that the controller is specifically programmed to receive.
Description. Network access control is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network. [ 3] NAC might integrate the automatic remediation process (fixing non-compliant nodes before ...

A network interface controller ( NIC, also known as a network interface card, [ 3] network adapter, LAN adapter and physical network interface[ 4]) is a computer hardware component that connects a computer to a computer network. [ 5] Early network interface controllers were commonly implemented on expansion cards that plugged into a computer bus.
Network security consists of the policies, processes and practices adopted to prevent, detect and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. [ 1] Network security involves the authorization of access to data in a network, which is controlled by the network administrator.
A network interface controller (NIC) is computer hardware that connects the computer to the network media and has the ability to process low-level network information. For example, the NIC may have a connector for plugging in a cable, or an aerial for wireless transmission and reception, and the associated circuitry.
