The data link layer and its associated protocols govern the physical interface between the host computer and the network hardware. The goal of this layer is to provide reliable communications between hosts connected on a network. Services provided by this layer of the network stack include: [2]
This is a list of cybersecurity information technology.Cybersecurity is security as it is applied to information technology.This includes all technology that stores, manipulates, or moves data, such as computers, data networks, and all devices connected to or included in networks, such as routers and switches.
Pivoting is usually done by infiltrating a part of a network infrastructure (as an example, a vulnerable printer or thermostat) and using a scanner to find other devices connected to attack them. By attacking a vulnerable piece of networking, an attacker could infect most or all of a network and gain complete control.
In computer security, a cold boot attack (or to a lesser extent, a platform reset attack) is a type of side channel attack in which an attacker with physical access to a computer performs a memory dump of a computer's random-access memory (RAM) by performing a hard reset of the target machine.
The attack surface of a software environment is the sum of the different points (for "attack vectors") where an unauthorized user (the "attacker") can try to enter data to, extract data, control a device or critical software in an environment. [1] [2] Keeping the attack surface as small as possible is a basic security measure. [3]
This attack is a type of Denial-of-Service (DoS) attack that is used to flood connected devices using CDP. [8] An attacker can exploit this functionality by sending thousands of spoofed CDP packets to the multicast MAC address 01:00:0C:CC:CC:CC to fill neighbor tables in any devices on the network that run CDP. [9] When this happens, other ...
The deception is designed to lure the attacker in – the attacker may consider this a worthy asset and continue by injecting malware. Deception technology generally allows for automated static and dynamic analysis of this injected malware and provides these reports through automation to the security operations personnel.
A denial-of-service attack (DoS) or distributed denial-of-service attack (DDoS) is an attempt to make a computer resource unavailable to its intended users. It works by making so many service requests at once that the system is overwhelmed and becomes unable to process any of them. DoS may target cloud computing systems. [5]
