Network Administration Jobs

Any organization with an online presence wants to ensure that this presence is seamless, and that users and customers can constantly access their website for information, or to purchase goods and services. A network administrator ensures that this technical support is solid, and works to quickly resolve any potential issues within the network, to make sure that all systems are a go when it comes to the organization.


This often includes testing the network for weaknesses, which could lead to resolving more deep-seeded technical issues that could have been lethal to the company’s growth. It also includes utilizing specific e-mail and internet filters to protect the organization from outside threats of all kinds, and ensuring that the company’s network is updated in every sense possible.

 

A network administrator’s role can be very different, depending on the organization, but almost always requires a diligent eye and a pro-active attitude when it comes to protecting the security and productivity of a company or organization. The position requires a tremendous amount of technical knowledge, and without network administrators, organizations would be susceptible to more attacks, and have much less network resilience, which is essential in terms of overall productivity.

    In this first part of the project you will use OMNet++ to simulate the basic behavior of two data link layer protocols, namely, Time Division Multiple Access (TDMA) and Carrier Sense Multiple Access (CSMA). The simulation you create will be run with different setups/scenarios varying the number of hosts and amount of data to be transferred in each run. For different amounts of data (file sizes) you will measure the average time to transfer the data while varying the host count. To simplify the simulation, we will assume that each packet is 1KB in size, and each file size correspond to certain number of packets, so a 100KB file needs 100 packets to be transferred successfully. In this second part you will use the INET Framework to build a simulation to better understand how the nu...

    Hi guys I had the Q locker virus last year; managed to decrypt my files but now I'm in the process of trying to wipe my drive clean autoruns and do an entire restart of my QNAP system with ALL SECURITY measurements and back up solutions in mind.

I'm absolutely fed up of the QNAP support as they aren't hands on at all and they don't communicate. I need someone to guide me through setting up the Qnap properly with extensive security and perhaps guide me on other steps I can take to increase security measures. I also use Plex media server which is why I would ideally still have Plex/the Qnap accessible online. I want someone to ac...

    Project: Macro : I need my PC to get connected to Irish IP when I'm abroad through VPN and multiple routers (see attached). I will travel with my PC. This PC will be connected to "router 2" through ethernet cable. Router 2 will be connected to local internet but will mirror the irish IP from router 1 which would stay in Ireland. I understand the macro but can't micro configure this myself. Therefore I'm looking for someone to do that. If you're interested just contact me and introduce yourself (background, work experience etc...) Videos : Cheers!

    I will provide JSON files with the extracted features (I will extract these from the pcap files). The features will be from malware and non-malware traffic, so the idea is to detect and classify the malware and non-malware samples. The feature selection should be done two ways: Manual and automated and we should be able to clearly identify the features that are being used and which features work well, and which features do not work well. As there are multiple datasets, we should be able to identify the features that work well across all the datasets. There are different versions of the malware, so we need to clearly identify which features work well across all these malware versions. The manual feature selection should allow me to select which features I want to use for the classificatio...
