Windows Networking

How Windows network DDNS replaces WINS in Windows 2000 and later. DDNS replaces WINS by allowing DNS clients to update the information in DNS database files. Because IP address and DNS record are synchronized, DNS and DHCP can be combined seamlessly. WINS listens to the NBT broadcast and when the DHCP lease expires it will not be able to update the IP address information as the NBT broadcast registers the machine's IP address to the WINS server at startup. Because NetBIOS is not routable, things are more complicated.

Malicious DHCP server DHCP server is widely used in Windows network. This is to make it easier to manage the IP address assigned to the client (and possibly even the server). But imagine that the wrong DHCP server is running on the network. What kind of damage does it give? Failure to use the dynamic DNS service may cause incorrect addresses to be assigned to the client, or the address pool to be used up immediately. When using dynamic DNS, the situation gets worse. If the client registers the incorrect address in the DNS database, the number of incorrect address resolution responses of the DNS server increases. Microsoft Windows 2000 provides several solutions to this problem. All DHCP servers running on the Windows platform must be approved in Active Directory to start distributing IP address leases to clients on the network. This operation can only be performed by the enterprise administrator, select "Action" | "Permit" in the DHCP console and execute it.

In contrast to platform networks such as Windows and iOS. Even without programs and applications, the value of the Windows operating system is very high. The value of all 3rd party programs and the value of interoperability with other users exceeds the value of Microsoft program itself (for users) only after the user and developer network becomes very large. Most products with network effects will eventually need to reach a critical mass in order to take full advantage of the defense power provided by that network effect. Before the network size reaches the critical mass, the product is still very fragile and may not be of much value to the user. In the case of such products, the challenge is to establish an initial value sufficient to motivate early adopters to start using the product before the value of the network effect begins.

The company has a network of Windows and Linux servers, commercial products, network management tools. Employees use mobile devices with business applications installed to improve productivity. In this respect, in order to operate the business smoothly, the IT network needs to function as much as possible. However, the risk of cyber security is as follows. You are the information security officer of a medium-sized company (1,500 employees). CIO will ask you to explain why it is important to protect Windows and Unix / Linux servers from known drawbacks and vulnerabilities. Please explain the steps you can perform to make the network infrastructure more secure to the CIO. According to the writing style of APA, this work requires 3 pages (minimum 500 words).
