DDOS attacks need more handling since DDoS attacks are divided into two general categories: 1) Application Layer 2) Network Layer6. To protect again DDoS attacks the organization may use cloud-based botnet DDoS protection service like Incapsula where malicious requests are automatically filtered out and only legitimate ones are allowed to pass through, enabling smooth traffic flow at all times.

...ACME’s list of needs for the new satellite offices and setup for the main offices needed a long list of supplies that were costly. Each part focused on being able to expand and be cost effective. The parts were also supposed to help eliminate downtime. An example of this is centralized management which bans certain sites from being accessed, and only allowing work websites to be accessed. All of these parts will reduce the office’s downtime and ensure that the loss of important files won’t happen. All information and documentation will be protected. The chart on the case study visualized the set up for the office with a central area containing a server and the central router and a WAP which will provide internet access and Wi-Fi for the office. A VLAN can be set up for the amount of computers needed and be able to communicate efficiently. This will allow employees to save data and store it in the same area. The satellite offices will not have a switch nor a server, they will use the centralized management from the main office. We will set everything up with wires using 52,800 feet of cable. On this VLAN that was created, you’d have to have all of the printers on it. I researched on how to centralize and manage printing, and I found out you have to Open the Control Panel and go to “Change advanced system settings” and turn on File and Printer sharing. This will enable you to start to share your printer on the VLAN. You choose your device and printers in the start menu and select...

The guidelines are approved by the AHA, AHIMA, CMS and NCHS that comprise the cooperating parties for the ICD-9-CM and ICD -10-CM/PCS. Reporting ICD-9-CM and ICD-10-CM codes on submitted claims ensures the medical necessity of procedures and services provided to patients during an encounter, which is defined as "the determination that a service or procedure rendered is reasonable and necessary for the diagnosis or treatment of an illness or injury. A 3-character category that has no further subdivision is a valid code. Codes that have an applicable seventh character are considered invalid without the seventh character. For example, a coder reports a code with the X placeholder in the 5th or 7th-character position is considered an invalid code, because that code requires "x" as a placeholder in either the 5th or 7th-character position. It would be incorrect if reported and results in a denied claim for third-party payer reimbursement. Claims can be denied if the medical necessity of procedures or services is not established. Each procedure or service reported on the CMS-1500 claim must be linked to a condition that justifies the necessity for performing that procedure or providing that service...
