The user can share the broadband or the connection with ADSL by using Ethernet cables. Smaller LANs can connect at least 2-3 computers using

Central Bank Heist: internal control weaknesses and techniques used to commit the fraud As part of the scandal considered being one of the largest bank heists in modern history, several internal control weaknesses were discovered, which left a country exposed to future potential threats and an increased need for awareness and information system upgrades. Such a devastating case prompted other Central Banks around the world to examine and upgrade their cyber security measures. In this heist of a
Three techniques can be combined to effectively combat SQL injections. Intrusion prevention(IPS), query level access control, and event correlation. IPS cannot only be the way to prevent as SQL injection strings are prone to false positive and may get a lot of alerts .If it is combined with query level access control then we may get accurate results. In Denial of Service access to network applications or data is denied to intended users. Denial of Service may be invoked through many techniques
the same Local Area Network (LAN) to communicate with each other. Without Active Directory, each computer on the network will operate as a standalone computer. Shiv LLC needs active directory to connect all computers on the network to each other. That is to say that all user’s information is stored in a central place, and not on the local computers’ hard drive. A global catalog is used to control the domain; the catalog keeps a record of all the devices registered on the network. A server running
