Nt1330 Unit 6 Lab 1

Decent Essays

Goal
The objectives of this lab were to install essential services such as Active Directory, Dynamic Host Configuration Service, Domain Name Service and Network Time Service on a Windows Server Platform. I used windows server 2016 technical review version 3 and successfully installed all the mentioned services on it. In this lab we used all services on windows as primary and I configured the services on Linux as secondary services.

Security Consideration
One of the important part of system administration should be secure, so it is very important to understand which factors can affect security inside and outside our system. There are many key decisions that have to be made, for example, what server operating system should a system use to which …show more content…

Linux Security
It is really hard to have an unbiased opinion about each server as the person working with one will normally argue that it is more secure but we should not mistake trust with security as these two are not equal.
Back in 1983 Department of Defense published series of book about security which had color code! The red book was related to network security and the security of system was discussed in the orange book. Base on the orange book an operating system based on its secure design and implementation can be in one of these categories: D, C1, C2, B1, B2, B3, and A1 which is from no security up to Verified protection. Base of Orange book and another evaluation system called Common Criteria both Linux and Windows has similar security. And most security based on how one server implements and being used on each platform.
Microsoft and Linux both provide support for authentication, access control, audit logging, Controlled Access Protection Profile, and cryptography. But , I think Linux is superior due to Linux Security Modules (LSM), SELinux. The user of a Linux system can decide to add additional security mechanisms to a Linux distribution without having to patch the …show more content…

We need to have a secure services and network and also it must be available sometime up to 24/7/365. To make sure that we are close to our Service level agreement (SLA) with our clients, we must check our performance to find the bottleneck. After identifying our bottlenecks we can plan and see what changes can improve our performance.
To measure the performance I used Opsview monitoring solution to monitor both DNS and DHCP on Linux and Windows server. Some sample tools like ping, nslookup and traceroute can be used in Windows and Linux to measure the basic metrics for DNS and DHCP. TO have a real data we need to test inside a real network or with some means generate the amount of traffic near the real traffic to find our network and services' bottlenecks.
For DNS we need also to test how long it takes authoritative DNS servers to respond to a request for your domain or host, including the Domain, the TLD, and the Root DNS server response times. This test provides us with information to help identify possible DNS hosting performance delays resolving our domain. It can be useful when evaluating the DNS performance of hosting providers, and general troubleshooting performance of a
