摘要:
A method for detecting and preventing a Distributed Denial of Service (DDoS) attack in a cloud computing environment including a plurality of clients connected to a server, the method includes collecting, by the server, file deoxyribonucleic acid (DNA) extracted from a file currently being executed by each of the clients and traffic information about network traffic caused by the file, from each client by using an agent that is installed in the client and that monitors the file currently being executed by the client. Further, the method includes analyzing, by the server, a risk level of a DDoS attack based on whether the file DNA of the file is malicious or unidentified and based on the traffic information. Furthermore, the method includes sending a command related to whether to block the file to the client according to the analyzed risk level.
摘要:
The invention relates to an apparatus for preventing infection by malicious code, comprising: a database in which files installed in an agent system, DNA values for each part of the files, and index information for indicating whether each file is normal or malicious are stored; a calculation unit which calculates a DNA value for a part of a file for which an execution is requested in the agent system; and a file inspection unit which searches the database to extract, in a group, files having the DNA value calculated by the calculation unit, inspects whether an object file is normal or malicious on the basis of the index information on the files extracted in a group, and allows the execution of the object file or makes a request for the calculation of DNA values of other parts which selectively include one part of the object file.

Disclosed is a swimming assistance apparatus, which is worn on a user's both feet to provide the user with buoyancy, such that the user can float on water and swim in a good swimming style while repeatedly moving the waist from side to side like a fish, thereby reinforcing the user's waist muscles. Persons who have knee joint arthralgia or backache or persons who have disability in the lower body can use the swimming assistance apparatus for medical purposes, such as pain relief or treatment.

Provided is a swimming assistance apparatus with an ICT function. The swimming assistance apparatus includes: a body part made of a material which floats on water or having a hollow tube which floats on water; a fitting hole formed in the body part and defined to penetrate through the body part to surround a part of a user's body; a cut part defined on at least one side of a wall of the fitting hole; and a sensor unit for measuring at least one of the user's posture information, work rate information and bio-information, so that the user's body floats on water by buoyancy of the body part when the user swims in a state where a part of the user's body is inserted into the fitting hole.
