College simplifies wireless access while increasing visibility and security New College was looking for a new security automation and orchestration solution. The IT office at New College realized that although their homegrown authentication and registration solution had succeeded for many years, new security measures were needed because of student-driven demand for campus-wide wireless and wired connectivity. Among other capabilities, New College needed a solution that would enable them to: • Dynamically manage switched ports that let students use the same password for wired as well as wireless access. • Configure VLANs more productively and assign membership based on level of membership access. • Reduce the incidence of virus-related…

Thesis: Using the principle of least privilege and roles to help secure a government network system. In high security government network systems with Department of Homeland Security, the use of roles and least privilege is necessary to help secure systems. It is essential to define an employee’s job role and provide the tools that are needed to perform their job. However, using the principle of least privilege is crucial in providing the employee access to only resources absolutely needed to…

Proper password security Passwords are is a convenient method of authentication the way it works is the system requires someone to enter a piece of information and then match it to the one that the system has if the information is correct the user will be able to access the system but there is some disadvantages of this some people may try to gain your password by looking over your shoulder or a brute force attack which implies that the person trying to require your password will try to maybe…

industrial control systems and enterprise networks makes it difficult to detect unauthorized activity in critical systems. 2. Least functionality: It is important for organizations to minimize and close unused services, ports, protocols, applications and functions that increases vectors for malicious party to gain access to critical systems. As unauthorized personnel could plug rogue devices into open ports or unplug an authorized device and connect to gain access to the network. 3.…

Wyoming Medical Center, Los Angeles County, and Raymond James all share similar struggles with how to secure the network, computers and mobile devices. Control and security are a concern from both inside and outside of the facilities and organizations. Each organization deployed a multi-level/tier approach was needed to protect the data. The Novell ZenWorks agents are used to manage the operating systems and software that is installed on the desktops/workstations; it allows the information…

environment for users located outside of the corporate offices. The remote users, outside of the corporate network, support various aspects of the business operations. Up to twenty percent of the company users may remote compute at any point in time. The current method of remote computing is based on a company provided laptop and a vpn connection to the corporate data center. In certain cases, employee owned computers are being used to make a vpn connection to the corporate data center. In the…

we have chosen, as well as the particular strategy we will use to handle each risk.  Table 1.2 – Risk Mitigation Strategies Risk Factor Mitigation Type Mitigation Strategy Building fire Mitigation Install proper fire containment systems in all site buildings; fire extinguishers near staff Server failure Mitigation Network administrators monitor hardware at regular intervals for deviation from baseline; spare parts are kept in secure storage…

The reason for blocking ports from the normal traffic is the access control. Firstly, firewalls used to block ports is to defend a network parties which is trying to access the internal service from outside. The unused and unsafe ports should be closed when they are not in use in case of the attacks through these ports. The blocking service prevents the DNS Spoofing, which is an attack to return an incorrect IP address as the response. Secondly, the firewalls restrict the service that are deemed…

regarding the principle of least privilege. This practice was implemented to restrict user access to certain aspects while still allowing them to produce maximum work efficiency. This whitepaper also uses real-world examples as well as theoretical examples to provide the reader a better understanding of the principle of least privilege. Though most examples shown can argue that this is not a flawless concept, the rarity of real life incidences prove that it is an effective practice that is…
