    IS 3230Unit 4 Assignment 1

    Looking at the network diagram provided I determined that the user, workstation, LAN, LAN-to-WAN, and system/application domains involved in the company should be redesigned to implement better access controls to provide multi-layered security. The most important access control implementation would be the user domain where the company should put emphasis on training; how to recognize social engineering attacks, how to create strong passwords, and how often they should be changed. The workstation domain should focus security via virus and malware scanning, operating system patching, and other types of application-level firewalls. To achieve a multi-layered security approach in the LAN domain I would recommend using an intrusion detection system (IDS) and an intrusion prevention system (IPS) to prevent unauthorized access. Security for the LAN-to-WAN domain should be implemented through the use of a firewall or DMZ to also prevent unauthorized access into the company’s network.…

    However, there is growing interest in protocols and other mechanisms for use with novel telecommunications services. Next-generation value-added services are bound to introduce new vulnerabilities. The interaction between all these communications and security protocols, and the mechanisms used for distributed systems security, is fertile ground for both interesting research. Ways to enhance these protection tools to make sure our technology is safe from IT attacks are evolving all the time. The systems or measures used to protect a company system at present might not be of any use in the future as technology is always enhancing to higher levels. Telecommunication businesses tend to be comparatively adept at managing information security risks. And many are taking action to achieve an enhanced level of ongoing insight and intelligence into ecosystem vulnerabilities and dynamic threats. Companies like Celcom must be ready to invest in this expensive research so as to be able to aggressively compete in the intense telecommunication market and to be able to sustain itself in this industry. Today, information security is a discipline that demands advanced technologies and processes, a skill set based on counterintelligence techniques, and the unwavering support of top executives. As telecom operators become more similar to technology companies, they will face a raft of new challenges. Core practices like employee awareness and training, policies and tools to reduce insider risks, and protection of data, including intellectual property, will need to be updated. The confluence of mobility, cloud, and social networking have multiplied risks, yet few operators have addressed these threats or deployed technologies that monitor user and network activity to provide insight into ecosystem vulnerabilities and threats. These…
