Application Of Access Control System

The system should also allow users to access the network from anywhere as long as they can verify authenticity. The system should also be able to prevent brute force attacks. The system should also make it possible for admins to see suspicious activity. Overall the components in the system should work as intended, to ensure top notch reliability and availability.

Privacy: In a wireless network all the devices are able to hear data traffic within their ranges which can be a threat to the security of the link. IEEE 802.11 counters this problem by offering a privacy service option that raises the security level of the 802.11 network to that of a wired network.

When you have a single server, users will have to login to their local machines via a local account. Any data that they would need access to on the network will need to be authenticated via a set of credentials on the server itself. The user in this case will be using two different set of credentials to access all of their data. When you move into a directory-based network with multiple servers in different roles, things become very easy for both the users and the administrators. The administrators will need to connect each computer to the domain that way the computer will become trusted and the user accounts will be able to be authenticated by the domain controller. Both the local computer logins as well as access to all of the data on each and every server will be the same and configured from just one location. This makes it easier for the

Formal user access control procedures must be documented, implemented and kept up to date for each application and information system to ensure authorised user access and to prevent unauthorised access. They must cover all stages of the lifecycle of user access, from the initial registration of new users to the final de-registration of users who no longer require access. These must be agreed by IDI. User access rights must be reviewed at regular intervals to ensure that the appropriate rights are still allocated. System administration accounts must only be provided to users that are required to perform system administration tasks.

The network level security will form the relationships of authentication, encryption and authorization for the wireless network and its connectivity between wireless clients to the internal network. Some recommendations are:

To improve security, the Wi-Fi uses various built-in WEP encryption technologies to prevent attacks from

Outline a wireless network and technology that you use regularly. The WLANs which are derived from the IEEE 802.11 standards, and marketed under the Wi-Fi trademark name. The WLANs security is neither forthright/candid nor simple, and it is continuously varying. Even though, as WLAN increase client output, they also expose the networks to a new group of potential hackers. With the present inherent security weakness of the 802.11 standard, all companies, small, medium or large, need to find out their security conditions derived from the applications using the WLAN. The standards also provide requirements for high-speed networks that support most modern-day applications. What sorts of security issues do

Windows 7, 8, 8.1 64bits. These types of an operating system have good performance and new features. These are the latest operating systems and same familiar OS should be used. These OS will be used in every client PC’s in the department.

The first server is the Domain controller which stores the users account information and responsible for authentications while also enforces security policy due to the Active Directory Domain

Users that have a wireless LAN should add security to ensure only intended users have access. Some safeguards include use of WEP (Wired Equivalent Privacy) encryption, IPsec, WPA (WiFi Protected Access), with a firewall or DMZ. A DMZ (demilitarized zone) is a physical or logical sub-network that separates the LAN from other entrusted networks

In Extensible Authentication Protocol, a random set of authentication mechanism is used such as using smart cards or certificates or using user’s credentials. Primarily the WLAN uses EAP for the purpose of passing messages during the authentication process.

WEP is an older security protocol for wireless networks that encrypts transmitted data. WEP uses a security code chosen during configuration called a WEP key, which uses a sequence of hexadecimal digits. WEP keys can be formed in different lengths depending on the type of WEP encryption being utilized. However it is generally not recommended to use WEP especially when we’re talking about networks that need more advanced security. The biggest disadvantage found with WEP is really it’s main weakness, a skilled hacker could actually crack the security key within a matter of minutes using special software.

Wireless media access will be protected using WPA2 security with AES 256 encryption and a pre-shared key to prevent eaves dropping.
