File permissions is used by allowing individual users and groups access to files based on a set of security settings for each file and directory. Linux uses a system of user IDs and group IDs to protect access to files, directories, and devices. Linux stores information about user accounts in the /etc/passwd file, and information about groups in the /etc/group file. Each user is assigned a unique numeric user ID, along with a text login name to identify the user in the system. Groups are also assigned unique numerical group IDs, and text group names.
Network devices provide a way for a computer or device to physically connect to the network via cable or media. The components of network devices are what allow a device to transmit and receive data. As a network becomes more complex, internetwork devices are used to connect between networks as well as networks using different protocols. Within every device is a network interface card (NIC) or network adapter. The NIC provides the physical connection between the device and the network (Ciccarelli, et al 2013).
The maximum amount of system memory supported by Windows 7 enterprise is 192 GB. Lesson 2 1. Windows Easy Transfer supports to types of migrations, called wipe-and-load migration and side-by-side migration. 2. When a serious problem occurs with Windows 7, you might be able to repair it by starting the Windows PE operating system and running diagnostic tools.
Basically, you would have two switches fed by the server. From there, you would have each station fed by one of the switches as well as any other network device like a printer. You would set security rights from the server software and each user would be able to have different security settings. 2. On a peer-to-peer network, each piece of the network would act like part of the chain would be both the client and the server.
Unit 4 Security Protocols Seminar PA 230-1 In the beginning of the seminar the Prof. Chaiacchia was discussing the information that we receive and give is very important to keep secure and confidential. Metadata was also discussed and is data about data. Unless you know how to access the metadata it will not be visible to the person viewing the file. You have to be careful when messing with a document and changing the metadata. The owner of the file will be able to tell if anything has been changed or modified.
Lab 6 – Introduction to Exchange Server 1. What server roles and components are installed if you select Typical Exchange Server Installation from the Installation Type page? Mailbox Role, Client Access Role, Hub Transport Role, Unified Messaging Server Role, and Management Tools. 2. What will be automatically created on your Mailbox role after selecting yes in the previous step?
Any ISP's network Define the Key Terms Computer networking: The gerund form of the term computer network. Computer network: A combination of many components that work together so that many different devices can communicate. Application: Generally, a function of any kind of computer or electronic device that is useful to the user, which can give the user a reason to want to own and use the device. More specifically, software that performs some useful function for a user. Email: Electronic mail.
With many network client devices, this results in the detected network displaying as an unnamed network and the user would need to manually enter the correct SSID to connect to the network. Unfortunately, turning off the broadcast of the SSID may lead to a false sense of security. The method discourages only casual wireless snooping, but does not stop a person trying to attack the network. It is not secure against determined crackers, because every time someone connects to the network, the SSID is transmitted in clear text even if the wireless connection is otherwise encrypted. An eavesdropper can passively sniff the wireless traffic on that network undetected and wait for someone to connect, revealing the SSID.
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. The system/application domain would require virtual testing of everything before any implementation, hardening of all servers, and keeping up with patches and updates regularly after testing has been completed. Some of the more efficient ways to implement better access controls in a company would start with the proper level of authorization policies including physical controls for facilities. The authorization policy would appropriate entry system access controls that specify what areas are to be locked at all times and what type of locking mechanism should be implemented. It would also include the implementation of secondary locks on specific equipment and storage cabinets within the facility, and training goals on the recognition and prevention of social engineering attacks.
Because transactions take place over the internet companies have to ensure that the customer’s personal information is safe along with the company’s information. Companies use different types of security programs to keep information safe from computer attacks. Computer attacks on a company can happen when the security program is not effective enough to keep these attacks from happening or from the lack of monitoring of the security program from management. The task of monitoring the security program is given to management, so companies should be held liable for losses sustained in a successful attack made on its AIS by outside sources. In the following an explanation of management’s role and why a company should be held liable.
