Network Security Assignment. Each of the organization's assets faces a security threat from within (internal) and from outside the organization (external).Security issues that will arise from within the organization (internal attacks) include access attacks such as eavesdropping (listening to a conversation that one is not part of) by fellow employees or through wireless networks, and snooping (looking through information files). Others include interception of transit information, unauthorized access to computers by employees, computer attacks by viruses, worms, Trojans, internal hackers and theft of hardware from within the organization (Maiwald, 2003). External attacks include hackers and cyber terrorists, and malware. The organization needs to address the measures that will be used to ensure the security of both information, physical hardware, internal and external attacks are checked.

Internal threats from employees are both intentional and accidental, where an employee can eavesdrop on another employee, hence gaining access to some information during conversation. In addition, employees can forge passwords of their colleagues and hence gain access to their computers, use, modify, and transfer information to other unauthorized members outside the organization. Moreover, employees may bring external or foreign insecure hardware into the organization, resulting in virus infection and transmission. Lastly, employees could steal portable small size hardware from the organization. Information and communication within the organization will be affected in one way or another. There might be lots of network traffic caused by attacks on the network, utilization of bandwidth by other clandestine programmes across the network, the security of both information and communication channels will face a threat.Encryption is one of the information security techniques that refer to the transforming of information (plaintext) using a defined algorithm so that the information becomes unreadable except to the parties involved who have the algorithm (hiding of information) to protect the information during transit.
