Download file to see previous pages In the context of network security definition, it consists of concerns related to network communication privacy, confidentiality of data over the network, accessing unauthorized classified data, access to prohibited network domains and utilizing Internet for concealed communication (Network Security. 2007). The security predictions that were published in an article for the year 2010 incorporates new advanced threats named as advanced persistent threats (APT), Cyber war escalates, VoIP attacks, Perimeter shrinks and harden, social networking sites, malware, DLP for intellectual property protection and malware as a service (MaaS) (Watchguard Unveils Top 10 Security Predictions for 2011. 2011). In order to protect the computer network, organizations emphasize on implementing hardware and software application as well as a security policy. This policy is followed by constructing a security policy document that defines rules and procedures. A typical security policy is constructed on a set of rules that defines authorization and access of network resources of an organization (, what is security policy? definition and meaning).The aim of implementing these security policies is to establish rules and procedures for improper use of network services. Moreover, the objective is to create a framework that will assist in identification and prevention of unauthorized access of network services (, Network Security Policy). Network security issues can lead to many different aspects. For example, if the server containing customer data is breached, organization will lose its credibility and trust among the customer and that will result in business loss. Similarly, if a critical system is hacked by internal or external sources, organization’s financial data along with goals and objectives can be revealed to other competitors. In order to eliminate the threats including unauthorized access, viruses, Trojans, malware and malicious codes, a security policy document is required. The document will provide a consistent framework to secure the integrity of the network along with eliminating risk abided by security threats and vulnerabilities. 2 Risk Assessment Risk assessment is a process to evaluate risks associated with threats and vulnerabilities to the network. Three factors will be considered in this scenario i.e. Assets, Threats and Security Priority Identification. 2.1 Assets The identification of information assets is vital before conducting risk assessment. Information assets are defined as the entities that hold organization data. A good definition is available on ‘’ which states it as, “information assets are specific to your business functions and business strategies, they may be contained within broad categories such as contractual and legislative compliance, those needing virus prevention, those critical to business recovery following security compromises, etc.” The information assets for an organization will be technology assets, data asset, service asset and people asset. In case of educational establishment the assets that need to be prioritized are: file space server, Linux web server, finance server, student database and email server. 2.2 Threats Threats are defined as ...Download file to see next pagesRead More

...Investigation of How Memory Is Implemented In a Modern Operating System Such As WindowsXP Microsoft Corporation recommends that computers running Windows XP have at least 128 megabytes (MB) of Random Access Memory (RAM) installed. For this memory size, Windows XP has shown itself to be consistently superior to previous versions of Windows. Performance only gets better with additional resources, particularly when you run memory-intensive multimedia applications. Many users will want to expand their computer's memory to take advantage of multimedia applications and to achieve even better performance. In general, adding memory is the easiest and most effective way to improve a computer's performance....

...Operating Systems The two sections that important for this discussion are the Linux I/O and Windows I/O. The Linux I/O service mainly offers the tools used for program profiling and monitoring the performance of the computer CPU. Disk scheduling in Linux allows the execution of many program processes at the same time. The Linux Page Cache aids in fast data access and transmission. This is because during an I/O operation, such as disk read information, the operating system kernel checks for data in the page cache to facilitate fast reading of the data. The advancements in the Linux I/O services is the optimization of disk scheduling through the use of...
