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.
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 ...
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 ...
Privilege (computing) In computing, privilege is defined as the delegation of authority to perform security-relevant functions on a computer system. [ 1] A privilege allows a user to perform an action with security consequences. Examples of various privileges include the ability to create a new user, install software, or change kernel functions.
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.
Penetration test. A penetration test, colloquially known as a pentest, is an authorized simulated cyberattack on a computer system, performed to evaluate the security of the system; [ 1] this is not to be confused with a vulnerability assessment. [ 2] The test is performed to identify weaknesses (or vulnerabilities ), including the potential ...
Outline of computer security. The following outline is provided as an overview of and topical guide to computer security: Computer security is commonly known as security applied to computing devices such as computers and smartphones, as well as computer networks such as private and public networks, including the whole Internet.
