It’s no surprise SQL (pronounced ‘sequel’) tops the job list since it can be found far and wide in various flavors. Database technologies such as MySQL, PostgreSQL and Microsoft SQL Server power big businesses, small businesses, hospitals, banks, universities. Indeed, just about every computer and person with access to technology eventually touches something SQL. For instance, all Android phones and iPhones have access to a SQL database called SQLite and many mobile apps developed Google, Skype and DropBox use it directly.

...Unit 2 Part 1 Shamica Jones Kaplan University Business Law September 1, 2013 The factors that indicate whether Davis owed Esposito a duty of care, so as to avoid allegations of negligence consist of three basic elements. “They are: 1. The likelihood that Davis’ conduct will injure others, taken with 2. The seriousness of the injury, if it happens, 3. Balanced against the cost of the precaution he must take to avoid the risk of negligence. . If the product of the likelihood of the injury exceeds the burden of the precautions, the risk is unreasonable and the failure to take precautions is negligence.” The Louisiana law that set precedents over trip-and-fall cases was Frelow v. St. Paul Fire & Marine Ins. The ruling in this case was that Louisiana law recognizes a legal duty on the part of employees to exercise reasonable care not to obstruct the flow of pedestrian traffic. Esposito was walking out of an exit of an arts and crafts show when Davis, an employee of the show’s producer decided suddenly to turn, without warning, and knock Esposito to the ground. One witness account said, “It appeared as if Davis had forgotten something because he snapped his fingers while quickly turning”. Davis admitted that he did not look when he turned. These factors indicate that Davis was negligent. It was the show’s producers’ responsibility to make sure that precautions were taken to avoid risk on the property. Esposito had to prove that Davis...

...Unit 1 Assignment 2 The Internal Use Only data classification standard of Richman Investments has many different infrastructures domains that are affected via internal use only data classification. More than all others, the three infrastructures that are affected the most are the User Domain, Workstation Domain and the LAN Domain. The reason why the User Domain infrastructure is one of the most affected infrastructures is because the User Domain infrastructure is the infrastructure that allows users to access the network. This is a problem because many users do not fully understand everything, all the time and thus is bound to make a mistake sooner or later. With so many users on our network, this is probably the most vulnerable domain infrastructures in our network. The Workstation Domain is also another domain infrastructure that has great reason to be affect by internal use only data because this is where the user connects to the our network. The reason that this can cause security threats and other problems is because this domain can be connected via a personal laptop or even a cell phone or other mobile device. The final infrastructure domain that is greatly affected is the LAN domain. The reason that this domain infrastructure is affected by internal use only data is because this domain is the open domain available companywide, to anybody in the building or even near the building via a wireless device. If we watch these specific areas closer and implement some......

...IS3340-WINDOWS SECURITY | Recommendations for Access Controls | Unit 2 Assignment 1 | | [Type the author name] | 4/3/2014 | | Access Control is the defined as “the selective restriction of access to a place or other resource”, in the RFC 4949. “The act of accessing may mean consuming, entering, or using. Permission to access a resource is called authorization.” Simply put the ability to read, write, modify, or deleting information or files is what Access Control is. It is more than this, in the permissions (authorization) granted to each Security Group or Individual User. The permissions mentioned in the previous paragraph are rights that a user is allowed to access, create, modify, or delete the file(s) inside a file folder, or objects. These are all permissions (authorizations) controlled by the Authorized Windows Security Personnel of the file structure. We will list some examples of how this outlined and what the impact would be, but first understand that requirements for the permissions is controlled from the Group Level, other than by Individual User, because it is easier to control from a security standpoint when you want to modify these abilities. There are four folders created (D:\ERPdocuments, D:\ERPdocuments\HRfiles, D:\ERPdocuments\SFfiles, D:\ERPdocuments\MGRfiles) which we want to allow specific permissions for certain functions (tasks). For example; by modifying the permissions under the specific user account for HRmanager to include...

...Eric Satchell NT1330 Service Provider Types Unit 2 Assignment 1 July 3, 2014 Comparing Service Providers There are a lot of companies providing services, but AT&T provided telephone communication to the public. AT&T monopolized the telecommunication industry until the United States took them to court for antitrust and won. AT&T was broken up into eleven smaller companies, call Baby Bells. One of the companies that derived from this law suit was the Regional Bell Operating Company or RBOC. RBOC was a term that described one of the US telephone companies that provided telephone, telegraph, and long distance to the consumers. RBOC is part of a local exchange carrier allowed to compete for business. RBOC services internet service which in turn dealt with digital data. The merging companies provided different types of service based on the Telecommunication Act of 1996. ILEC or incumbent local exchange carrier is a telephone company that provided local telephone communications before the ruling to break up the Ma Bell Company. The FCC ruled that the ILECs must provide other telecommunications service providers access to their equipment to be able to provide a better rate to the consumer. This......

With company users, any outsiders, contractor’s or third party agents will also need to agree and comply with the Acceptable Use Policy. Any violation will be taken up with management or the proper establishments to access further corrective action. Work Station Domain: This is where most of the company’s users connect to get to the IT set-up. No personal devices or removable media may be allowed on this network ever. All devices and removable media will be issued by the company for official work use. Access Control Lists (ACLs): ACLs will be tired up to appropriately define which access the users are allowed to use.

...Introduction to Networking Unit 2: Assignment 1 Indentifying Network Topologies Identify the major needs and major stakeholders for computer networks and network applications. The major stakeholders for computer networks and network applications are the ones who use it or relay on it to do business. The main stakeholders are the ones who uses the network or applications to get their work done for their company. The next stakeholder is the company or people who rely on the first company to get what they need. The ones who design the applications or the network are stakeholders in the fact they need to make sure their work is done properly so others can do their job. The owners are also stakeholders in the fact that others rely on their people and software to get their work done. Then there is the end-users who are also stakeholders because we need the network and applications to do our daily job. Identify the classifications of networks and how they are applied to various types of enterprises. PAN (Personal Area Network)—personal. You as an individual and the range is around that person LAN (Local Area Network)—network of interconnected computers within a small geographic area. Area of LAN’s are a room, building or group of buildings, offices, schools. The range is 10m – 1km MAN (Metropolitan Area Network)—a network design for a town or a city.

...10/ 1/ 2014 NT2580 Unit 2 assignment 1 The workgroup consists of three primary workgroups, which contain group membership lists of users within the Active Directory infrastructure that currently exists on the SMB Server that is located within the confines of the LAN structure. The security breach, which is defined as any event that results in a violation of any of the CIA (confidentiality, integrity, availability) security principles, was caused by the SMB server being accessed by an unauthorized user due to a security hole that was detected by the server software manufacturer the previous day. The security patch will not be available until possible as long as three days, but hopefully within that timeframe. In addition, the LAN administrator needs at least one week (minimum) to download, test, and install the patch. To calculate the Window of Vulnerability (WoV) for this security breach, the following timeline will be used as a guideline to determine the basis for calculation: First it is important to understand the variables considered in this timeline formula. The WoV is the period within which defensive measures are reduced, compromised, or lacking. The WoV covers a timeline from the moment vulnerability is discovered and identified by the vendor. It also includes the time taken to create, publish, and finally apply a fix to the vulnerability. It is also important to explore the device(s) that were targeted by the attack. In this instance, being the SMB server within...

Unit 2 Assignment 1

...NT1310 Week 2 – Unit 2 Assignment 1 Service Provider Types There are five different types of telecommunication types to date. First of which is RBOC – (regional bell operating company) which was a telephone company created as a result of the breakup of AT&T. The seven original regional Bell companies were Ameritech, Bell Atlantic, BellSouth, NYNEX, Pacific Bell, Southwestern Bell, and US WEST. The reason why this was so important was because these companies are what provided local telephone service while AT&T provided the long distance phone service. These are what made up the Local Exchanges or the LEC’s. ILEC or incumbent local exchange carrier was a telephone provider that provided local service prior to the telecommunications act of 1996. These play a major role because these carriers are what own the local loops/exchange and facilities in that area. CLEC’s are the exact same thing except they are the competitor to the ILEC’s but provided their own networking and switches for local service. MSO or Multi system Operator – is owner of multiple cable and satellite television systems. This ties into what an ISP is. An ISP is simply and Internet service provider that provides a mean for accessing the internet. MSO is majorly known for being cable companies, because of this cable companies are providing internet to cable customers (usually as bundles with their plan). They work within each other because......

Unit 2 Discussion 1

...Unit 2 Discussion 1: Familiar Domains As an IT Admin you mainly deal with all seven domains, but the ones I deal with currently are work station, user domain and remote access. In any environment that you work with any of these 7 domains countermeasures are needed. It’s very important to make sure your network is secure and there are quite a few actions to take to ensure that it is safe as possible. Although no domains are 100% secured it’s always good to make sure all updates and patches are up to the most recent. I will also name a few other ways to protect certain domains in a typical IT infrastructure. Some countermeasures to take for user domain are making sure to have all users aware of security. Also have restricted access for a company’s terminal server and observe abnormal employee activity. Anti-virus is also needed to make sure the computers servers aren’t infected with malicious programs that cause loss in important documents. With a work station you can add a firewall to prevent unwanted traffic from infiltrating the network. Ensuring that your workstation has the latest service packs and patches update will also help protect any holes that could lead to hacking. Also with remote access it’s good to make sure only that person has access to certain files and must keep their password secure and not make a weak password so it does not get compromised. All these......
