Detecting preventing or mitigating DoS or Distributed DoS attacks Research Paper

Detecting preventing or mitigating DoS or Distributed DoS attacks - Research Paper Example This process requires a large network of computers running malicious program. To acquire the network, the attacker uses software that recruits vulnerable computers (Glen, 2013). That is, the computers with improperly patched antivirus, out of date antivirus and without antivirus (FU, 2012). To recruit machines into his/her DDoS attack, the attacker may follow several processes. Firstly, the attacker may use a machine infected with malicious programs to search, find, and infect another machine (Patrikakis, Masikos, & Zouraraki, n.d.). The infected machine joins the previous in the haunt of the unprotected machine and infects them. Secondly, the attacker may create a long list of the machine he/she want to recruit before infecting them with the malicious software to make them join his/her army of attacking computers (Glen, 2013; Patrikakis, Masikos, & Zouraraki, n.d.). Notably, some public servers, when compromised, become effective to the attacker when creating the hit list (Patrikakis, Masikos, & Zouraraki, n.d.). For instance, the attacker may run topological scanning where one machine is infected and finds other machine to infect through url it stores (UMUC, 2012). Local subnet scanning uses a compromised host to attack another computer within its own network without firewall detection as it uses the information stored in the local addresses (UMUC, 2012). Lastly, permutation scanning infects the machines allocated a regular pseudorandom combination record of IP addresses (Patrikakis, Masikos, & Zouraraki, n.d.). It searches for uninfected machine in the IP addresses and infect it. When it identifies the infected machine, it jumps over it to the uninfected (UMUC, 2012). The process stops when the infected machine finds several infected machines while it scans (Patrikakis, Masikos, & Zouraraki, n.d.). There are various frames used in the wireless network as a way of

What is the role of management information systems in the reporting Essay

What is the role of management information systems in the reporting process in a multinational enterprise Discuss the statement, Inadequate MIS in foreign affiliates can become a control problem for MNEs - Essay Example Therefore, these management information systems and the information produced by them are usually considered as crucial components of sensible and practical business decisions. For effective management in the organization, an MIS provides decision makers with facts and supports and enhances the overall decision making process. For top management and local managers, it provides the data and information that is needed to assist the board and management in making strategic decisions. At other levels, management information system offers the capabilities for monitoring and distribution of information to the management, employees, and customers (Comptroller of the Currency, 2000). Information management with in an organization is a sequence of processes that assists the organization in managing the information that flows across organizational units, identifying information needs, obtaining the information, storage and organization of information, developing information products and services, distributing information, and using information that information for effective decision making. Managing the information in this way proposes new strategies for getting the most out of the value of information in organizations, and for a redefinition of the roles of organizational professionals, be they top management, local managers, employees, or other staff (Choo, 1995). Now a days Managers have to cope with high information-processing demands in various circumstances because of the uncertainty of environmental factors and the increasing complexity of organizational activities. Operating in international markets has resulted in significant increase in information- processing demands for top managers. International growth may also cause increased proper information management demands because of the reasons such as: more complex organizational structure of MNEs, communication problems, and the geographical distance between the head office
