4. Security Security is a very critical issue in many systems, especially distributed systems. This is because the system is distributed across a network over many devices, and so there may be more ways for outsiders to access the system who do not have permission to do such. A security breach is considered to be any time an unsafe state is reached within the system. An unsafe state is one in which data can be illegally intercepted, interrupted, modified, or fabricated. Since a distributed system
problems that arise in the management of information in each section manager, accounts, production and personnel in the company. After analyzing the information obtained by the company, proposed to create a virtual local area network (VLAN) and access control list (ACL). 2.0 Company Background Al Ikhsan is a company selling athletic shoes in the premises at the address Address Lot F.43, First Floor, Ipoh Parade, 105, Jalan Sultan Abdul Jalil, Greentown, Silver Silver Postcode 30450. States are also distributors
disadvantages that cannot be ignored: 1.1 . ACCESS CONTROL LISTS i. Access lists are great for doing simple filtering and security for basic networks. However, there are some things to keep in mind when building and implementing them. First, the longer an access list, the more processor time it uses. Really long access lists can slow your router down significantly and even put an appreciable wait time for users trying to access machines on your network. ii. Second, access lists are not dynamic, so they cannot
of undesired communications. Should a packet come from outside the network, in an attempt to pretend that it is a response to a message from inside the network, the firewall will have no record of it 's being requested and can discard it, blocking access. As many communications will be transferred to high ports, above 1023, stateful inspection will enable the system to determine which sets of high communications are permissible and which should be
between Mandatory Access Control (MAC), Discretionary Access Control (DAC) and Role Based Access Control (RBAC) Models in Database Management Systems Abstract This paper includes the comparison between access control models Mandatory Access Control (MAC), Discretionary Access Control (DAC) and Role Based Access Control (RBAC) and explores the advantages and disadvantages of implementing the subjected models. They provides the fundamental policy and rules for the system level access control. . Role-based
information is protected against disclosure to unauthorized users (confidentiality), improper modification (integrity) and non- access when required (availability)." (ISACA.org, 2017) With confidentiality we refer to information that can be accessed only by authorized people. For instance, the use of passwords to access to software/files, or a personal badge used to access specific areas of the building. Integrity is directly connected to confidentiality and refers to accuracy Information Technology
SOX Compliance: Eleven Essential Controls for the SME Small to mid-sized enterprises (SMEs) can benefit from implementing control objectives for governance, compliance, and improved security. The Securities and Exchange Commission’s (SEC) recent Sarbanes-Oxley (SOX) announcement puts an end to several years of speculation, so SMEs must get on top of their control game. Executive Summary Sarbanes-Oxley (SOX) is here to stay for small to mid-sized enterprises (SMEs), which the Securities and
all other ports blocked. An e-mail server may have only necessary ports for e-mail open, with others blocked. A key to security policies for firewalls is the same as has been seen for other security policies, the principle of least access. Only allow the necessary access for a function, block or deny all unneeded functionality. How an organization deploys its firewalls determines what is needed for security policies for each firewall. The security topology will determine what network devices are employed
forms of data representation or structure are prone to multitude of possible threats/attacks due to the mode of accessibility. Common attack in this has been the denial of service (DoS) attack. This type is more linked to the Web server allowing access to the database, but can also be attached to database itself. A couple of measures can be implemented such as use of firewall to secure the web servers as well as the databases. The information sent and accessed over the distributed systems or network
and State Manager’s Accountability Act of 1983, which “…requires that the head of each State agency establish and maintain an adequate system of internal control within their agencies. A key element in a system of internal control is separation of duties” (Department of General Services of California, 2008). The manual then goes on to list explicitly how entities are designated, the actions they may take, the number of actions each entity may take, and the level of authorization for each duty

architecture models are implemented into computer hardware and software, some are implemented as policies and practices, and some encompass both Information security is made up of three main attributes: Availability is the prevention of loss of access to resources and data. Integrity is the prevention of unauthorized modification of data, and Confidentiality is the prevention

unauthorized entries and hackers INTRODUCTION Over the past few years, Internet-enabled business, or e-business, has drastically improved efficiency and revenue growth. E-business applications such as e-commerce, supply-chain management, and remote access allow companies to streamline processes, lower operating costs, and increase customer satisfaction. Such applications require mission-critical networks that accommodate voice, video, and data traffic, and these networks must be scalable to support

Kerberos was conceived as a secure network authentication technology at Massachusetts Institute of Technology (MIT), where it continues to evolve. Using encryption as a seal, Kerberos credentials, or tickets, vouch for authenticated users. Because every node on the network exclusively trusts the Kerberos server, users' credentials are valid throughout the network. This way, they theoretically have to log in only once. In addition, Kerberos can provide support for real-time encryption of network communications
separated the parts of a building, saving both lives and property. In late 1980s, network securities of firewall were been used to distinct networks from others. Firewall also can be defined like a system or group of systems have two networks over an access control policy. Nowadays, internet security has been a major consideration when someone builds an organization. This is because, by using firewall. It can protect and shield the secret data and file s of an organization. The firewall is very important
also risks that surround it as well. The first major risk is that BYOD makes it easier for untrustworthy employees to steal a company’s information because they own the device they used to do it. A company can manage this risk by having strong access controls, encryption, and endpoint security software to prevent data fro...
Wireless Communication Security Abstract In today’s society advances in technology are growing rapidly. Businesses and people are taking full advantage of the improving ways of transmitting data internally and externally. One of the mediums today in transmitting data is via wireless communication systems. It is obvious that this data will need to be secure for many reasons. These will be the questions I will pose in this paper. Will this be a secure means of transmitting data? How
