...Describe the functions and use of different Servers in benefitting a small web-presence business needs With the 21st century been in the digital era the use and need for technology and computers is increasing and people want everything right there in front of them with only one click away. Web servers Web servers deliver web content from anywhere in the world to your computer, they can either be software which is a computer application the aids the delivery of web content or they can be hardware so the computer itself that delivers web content. A web server works by breaking the URL down into 3 parts, the protocol (http), the server name (web address) and the file name. So your computer communicates with the server name translating it into an IP address which will connect to the desired web server, following the protocol the browser sent a request to the web server asking for the file name and text. A web server can benefit a small business as since it’s designed to run multiple applications such a messaging, databases and email. Having a server makes it easier for your employees to communicate and share data. Due to the server being able to store images, documents etc. It can be used as a hub for sharing information with colleagues, with being able to access the server from anywhere in the world. Most servers are...

...Pfsense firewall linux servers My responsibilities are mainly involved with networking, Linux and security. When installing a new Linux server I have to partition it to fit the needs of the application that will be running on it. Partitioning is essentially managing the hard drive space. I have to anticipate the different needs for each server. For example a ftp server would require a lot more space in the home directory, as each user would be likely storing files in their respective home folder. Partitioning is also used for security as the partitions can be mounted with their own “rules”. For example, the /temp mount point can be mounted with the noexec option. This would prevent executable files being ran in this partition. The noexec option is very important for temp as when a hacker gains control of a system they tend to have a low level account. These low level accounts typically have access to the /temp partition. This is where it is likely a hacker will download a local privilege escalation exploit to gain root privileges. This can break applications, that is why planning is very important for me when setting up new servers and applications. Then there are general rules that have to be applied for all servers. For example, creating separate large partitions specifically for logging. Since this has little chance of breaking anything and is very important this is done on all servers. The logs are important for troubleshooting application issues and auditing...

Avira Server Security is a recommended choice for network that consists of a variety of server points. The anti-virus software updates automatically, including back-up server protection, ensuring all data is protected without the need for an automatic patching systems. A penetrating testing schedule should also be included, along with policy and procedure on how to safely carry out testing by trained administrators, to exploit system vulnerabilities. The handling of sensitive data within departments can be monitored by using monitoring software on desktops, or watching corporate traffic on system network. Monitoring software send all activity and history logs to the Information Technology department, this can be reviewed or analysed at any particular time, to monitor how data is being transferred or handled both internally and externally. These measures can indicate whether the right protocols are being followed within each department. A penetrating testing schedule should also be included, along with policy and procedure on how to safely carry out testing by trained administrators.

It’s benefits include being free for initial start-up, provides secure cloud-based technology and meets the highest standards for maintaining data confidentiality and secure sharing of information (Kareo, n/d). The recommended hardware for UMUC were 1 Desktop Macintosh: Intel or PowerPC G5 with 2GB or more of RAM, 3 iPad Air laptop for examination rooms, 5 Mbps or greater, Firefox 28 or higher on Mac OS X, Apple iOS 5/6 Communications will come from local phone and internet provider (e.g. Verizon or Comcast) both of the options provide high speed service. KAREO also offers Dr. Martin and his staff with a support staff for any issues pertaining to the program. It will also be vital that Dr. Martin, Vivian and Manuella are up to speed and trained equally on the hardware and software. With all member of this team being trained, it will ensure that it can improve the patient visit process currently at the clinic, in addition to the investment of patient check-in kiosk which can alleviate the 1-2 wait times also allowing the nurses to spend more time prepping rooms, attending to patients and less time at the front desk....

... Discussion Forum Student’s Name Institution Affiliation Discussion Forum Question One The responsibility to design the ER model and ensure that it is regularly updated lies with the database administrator. Rather than focusing on a single department or user, the database administrator assesses overall requirements and maintains the database in a manner that benefits the entire organization (Scott, & Rosenblatt, 2017). The ER model is a systems analyst function and not a clinical analyst function since it entails both development and maintenance and focuses on the entire organization. Decision support models such as the clinical information system strategic planning model can be created and maintained by the clinical team rather than the system team. Clinical teams are teams that provide clinical care (Mosser, & Begun, 2013). Decision support systems are critical to the accomplishment of this objective and so clinical teams should be heavily involved. Question Two I would recommend the third approach which entails providing the patients with a list of primary care physicians to select from when registering. Key fields are an essential part of system design since they facilitate effective organization, access, and maintenance of data structures within the system (Scott, and Rosenblatt, 2017). Primary and foreign keys are examples of the various key fields that can be utilized when designing the system. The primary keys that will be used for the patient data...

...Brian Phelps NET260 W01 October 9, 2014 Activity one has us configure the essential security settings for group policy. Theses settings could be the Account Policies which can control Password Policy, Account Lockout, along with Kerberos. For the security you want to take into consider attion how much time you want to go by before haveing the user renew there password. I personally would set the minimum password age for atleast one day then the maximum 60 days. This way they would be forced to renew their password. I would also set the Enforce password history to ten since it would be roughly 1.5 years before the user could resuse a password. I would also change the Account lockout to 3 to give the user atleast three tries to login. The Keberos I might change or leave as is. I could see using this while intially configuring Acitive Directory and Group Policey or making changes to enhance security....

...Question 1(a) VPN is called Virtual Private Network. The objective of VPN is to provide a secure private connection between networks over the public network. It is commonly used in business due to the factors stated below: • When data is transferring on the private network, the data will be secured to prevent hackers to try and extract the data due to encryption. • • Employees are allowed to remote into the company network effortlessly There are two types of connections that are being used for VPN. They are remote access VPN connection and site-to-site VPN connection. • Remote access VPN A remote access VPN connection allows the user to set up a private connection to the company networks. The user is able to access private data in the company server remotely, even if they are not physically in the company itself. The user will need to have VPN client software to be installed on the computer. The software will enable you to establish a connection to the VPN server. The software also handles the encryption to keep the connection safe and secure. • Site-to-site VPN A site-to-site VPN connection allows offices in various locations to set up a secure connection over a public network. This connection is normally used for branch offices to access information from the main office. VPN is able to make use of tunneling to create a private network across the internet. Tunneling is a process to encapsulate the packets of data to outer packets before delivering the data through the internet...

...image-recovery. The content owner first encrypts the original image using an encryption key to obtain an encrypted image. Then, the data-hider compresses the least significant bits (LSB) of the encrypted image using a data-hiding key in order to create a sparse space to accommodate some additional data. At the receiver side, the data embedded in the created space can be easily retrieved from the encrypted image according to the data-hiding key. Since the data embedding affects only the LSB, a decryption using encryption key can then result in an image similar to the original one. By using both the encryption and data-hiding keys, the embedded additional data can be successfully retrieved and the original image can be perfectly recovered [2]. This paper proposes a method for distinct revocable data hiding in ciphered image. As shown in Fig. 2, the content owner initially reserve enough space on original image and then converts the image into its encrypted form using encryption key. Now, the data embedding process in encrypted images is inherently reversible for the data hider as he only needs to accommodate data into the created space. The data extraction phase and image recovery phase are identical to that of Framework Vacating room after encryption. In the new framework, we follow the idea that first losslessly compresses the redundant image content and then encrypts in order to protect privacy. Next, we consider a practical method based on the Framework “Reserving room before encryption”...
