You have heard of the term quality-of-service (QoS) and know that this could be implemented to prioritize traffic flow as it moves across the network. You do not have all of the details about how QoS works, but want to because you believe it could help.

Using all available resources, complete research on QoS. In 4–6 paragraphs, addressed the following:

  • Describe quality-of-service.
  • Describe why you believe it is important to have this technology configured in a network. Provide at least 1 example of how it could be beneficial.
  • Describe a time that you have utilized quality-of-service in your job. If you have not utilized QoS, describe a situation where you believe it would have been beneficial. Be specific with details in your discussion.

Computer Science 2023 Operation Security

2023 The following scenario is based on an actual attack deconstructed at a seminar I | Assignment Collections

The following scenario is based on an actual attack deconstructed at a seminar I attended earlier this year. The names and locations have been removed to preserve the privacy of the organization in question.

Background:

No-Internal-Controls, LLC is a mid-sized pharmaceutical company in the Midwest of the US employing around 150 employees. It has grown over the past decade by merging with other pharmaceutical companies and purchasing smaller firms.

Recently No-Internal-Controls, LLC suffered a ransomware attack. The company was able to recover from the attack with the assistance of a third party IT Services Company.

Attack Analysis:

After collecting evidence and analyzing the attack, the third party was able to recreate the attack.

No-Internal-Controls, LLC has a number of PCs configured for employee training

These training computers use generic logins such as “training1”, “training2”, etc. with passwords of “training1”, “training2”, etc.

The generic logins were not subject to lock out due to incorrect logins

One of the firms purchased by No-Internal-Controls, LLC allowed Remote Desktop connections from the Internet through the firewall to the internal network for remote employees

Due to high employee turnover and lack of documentation none all of the IT staff were aware of the legacy remote access 

The main office has only a single firewall and no DMZ or bastion host exists to mediate incoming remote desktop connections

The internal network utilized a flat architecture

An attacker discovered the access by use of a port scan and used a dictionary attack to gain access to one of the training computers

The attacker ran a script on the compromised machine to elevate his access privileges and gain administrator access

The attacker installed tools on the compromised host to scan the network and identify network shares

The attacker copied ransomware into the network shares for the accounting department allowing it spread through the network and encrypt accounting files

Critical accounting files were backed up and were recovered, but some incidental department and personal files were lost

Instructions:

You have been hired by No-Internal-Controls, LLC in the newly created role of CISO and have been asked to place priority on mitigating further attacks of this type.

  • Suggest one or more policies that would help mitigate against attacks similar to this attack
  • Suggest one or more controls to support each policy
  • Identify each of the controls as physical, administrative, or technical and preventative, detective, or corrective.
  • Keep in mind that No-Internal-Controls, LLC is a mid-sized company with a small IT staff and limited budget
  • Do not attempt to write full policies, simply summarize each policy you suggest in one or two sentences.  
  • Clearly indicate how each policy you suggest will help mitigate similar attacks and how each control will support the associated policy
  • 3-5 pages in length.
  • APA format.. citations, references etc…
