First Response

The NFS offers the Linux and UNIX users the ability to share and even transfer information and data from a single PC to another. The NFS system is highly available in the Windows operating system, more than it is in the UNIX system. The NFS, however, can be loaded by the use of the Server Message Block (SMB), which make up the CIFS. The NFS processor makes information readily available. The operation of the NFS system depends on the relationship between the UNIX and the Linux operating systems. For the information to be transmitted from one place to another, ...

Network Security.

Network security is primarily the protection of data, files, and directories in a computer from unauthorized access. As a corporate network administrator, it is paramount to secure such records and foster client confidentiality. Any security breach/ attack affects the confidentiality and the integrity of the system. There are various types of network attacks which affect different organizations. A close-in attack is one of the most common types of attack.

Answer 1: Wired Equivalent Privacy (WEP) is not a very robust and secure protocol. There are many free tools available which even naïve hackers can use to crack the security where WEP is used. Thus, with very simple programs and tools WEP keys can be cracked. Once done, the hackers can connect to the Wi-Fi network and even decode the traffic on this network (Stobing, 2014). Answer 2: Instead of WEP, we should use Wi-Fi protected access (WPA) or Wi-Fi protected access 2 (WPA2). The encryption which this protocol uses is AES/ CCMP which is very robust and ...
