Mandatory access control

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…

boundaries between 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…

Thesis: Security is a big concern as hackers have reasons to obtain personal data for monetary gain. Network security risks are increasing and becoming more complex, resulting in many obstructions for information systems specialists. Security threats appear to accompany every new technology invented. I. Security Policy Guidelines Policies are considered highest level of documentation, from which the other major standards, procedures, and guidelines run. Security policy changes over time,…

biometric template has been built and securely stored on a server within a database, the biometric template is scanned into a system in a request for access. When access is requested, the template is recalled and compared to what is located on the network server as described by the template. When a match is identified, access is granted, and if not then access is denied. Blended Attacks…

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…

do not charge it; for mobile phones, if the device is ON, power it down to prevent remote wiping on data being overwritten. - Ensure that you do not leave the device in an open area or other unsecured space. Document where the device is, who has access, and when it is…

Abstract This whitepaper will review the concepts, how to apply them, and issues that arise 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…

1. Message confidentiality means that a message being sent cannot be read by anyone other than the intended recipients, and message remains confidential and it cannot be read by unauthorized ones. Integrity defines the process of data is modified based on cryptographic procedures like hashing and message code techniques that ensures the message is not modified. A message which is encrypted that is modified in transmitting can't be determined the original text, but rather will not have integrity…

Network intrusion takes place when an outside entity gains access to a prohibited network without authorization. A secure computer or network system should provide data confidentiality, data and communication integrity and assurance from a denial of service attack (Mukherjee, Heberlein, & Levitt., 1994, p.28). Network intrusion can have huge effects on an organization as data can be stolen, modified or erased, and equipment or programming can be harmed or annihilated. Organization in the…
