Network Assessment and Defense Training Manual

You work for Strategic Security Consulting Group (SSCG). Recently, one of your clients located in Los Angeles, North Star Software Developers (NSSD), called with a big problem. NSSD’s strategic security goals include protecting the software development process and code as well as sensitive client information from internal and external breaches. Some of its network servers were compromised, resulting in the possible loss of personal information and credit card numbers of purchasers of the company’s software products. It is not presently known whether this attack came from inside or outside of the company. NSSD is currently dealing with this problem as best as it can, but it needs your company to help prevent this from happening again in the future. You have been assigned to create a training manual for NSSD’s IT personnel in which you test, describe, and recommend a variety of network security tools that, when used properly, will mitigate both the risk of future breaches and the effects of a breach when it takes place. Given the above scenario, you will also create an executive overview that describes the appropriate areas of concern from your research in this course. This should be written in language that can be understood by a nontechnical audience of company management and stakeholders. In this assignment, you will demonstrate your mastery of the following course outcomes: Interpret results of network and vulnerability scans for identifying security vulnerabilities Implement appropriate methods that protect against and address network threats and vulnerabilities using appropriate risk mitigation techniques Categorize the severity of security incidents using industry best practices for determining the appropriate immediate response Recommend timely countermeasures that minimize the consequences of current security incidents Communicate response and mitigation strategies that align with an organization’s strategic goals Prompt Specifically, the following critical elements must be addressed: Network Assessment and Defense Training Manual: Executive Overview Create a brief description of the purpose of the manual that is in consumable terms for the stakeholders. Be sure you address the company’s strategic security goals and the value of the policy changes or updates. Assess the role of network defense methods and strategies for securing the network. Support your findings with research and experience from the lab exercises. Evaluate the role of mitigation methods and strategies in reducing security risk. Support your findings with research and experience from the lab exercises. Summarize the role of incident response methods and strategies in minimizing the impact of breaches. Support your findings with research and experience from the lab exercises.

Network Assessment and Defense Training Manual

Executive Overview

This manual is designed to provide IT personnel at North Star Software Developers (NSSD) with the knowledge and skills necessary to assess and defend the company's network against security threats.

NSSD's strategic security goals include protecting the software development process and code as well as sensitive client information from internal and external breaches. The recent breach of NSSD's network servers demonstrates that the company needs to improve its network security posture.

This manual will cover the following topics:

Network assessment: How to identify security vulnerabilities in the network.
Network defense methods and strategies: How to protect the network from security threats.
Mitigation methods and strategies: How to reduce the risk of security breaches and minimize the consequences of breaches that do occur.

Full Answer Section

The policy changes or updates that are recommended in this manual will help NSSD to achieve its strategic security goals and reduce the risk of future security breaches.

Role of Network Defense Methods and Strategies

Network defense methods and strategies are essential for protecting the network from security threats. These methods and strategies can be used to prevent attacks from happening in the first place, or to mitigate the effects of attacks that do occur.

Some common network defense methods and strategies include:

Firewalls: Firewalls can be used to block unauthorized access to the network.
Intrusion detection systems/intrusion prevention systems (IDS/IPS): IDS/IPS systems can be used to detect and block malicious traffic.
Access control lists (ACLs): ACLs can be used to control who has access to what resources on the network.
Data encryption: Data encryption can be used to protect sensitive data from unauthorized access.
Security awareness training: Security awareness training can help employees to identify and avoid security threats.

Role of Mitigation Methods and Strategies

Mitigation methods and strategies are used to reduce the risk of security breaches and minimize the consequences of breaches that do occur.

Some common mitigation methods and strategies include:

Vulnerability scans: Vulnerability scans can be used to identify security vulnerabilities in the network.
Patch management: Patch management is the process of applying security patches to software and operating systems.
Incident response planning: Incident response planning is the process of developing a plan for responding to security incidents.
Backups: Backups can be used to restore data that has been lost or corrupted due to a security breach.

Conclusion

Network assessment and defense are essential for protecting networks from security threats. By implementing the network defense methods and strategies and mitigation methods and strategies described in this manual, NSSD can reduce the risk of future security breaches and minimize the consequences of breaches that do occur.

Recommendations for NSSD Management

I recommend that NSSD management take the following steps to improve the company's network security posture:

Implement a network security program. This program should include a risk assessment, vulnerability scanning, patch management, incident response planning, and security awareness training.
Invest in network security tools and technologies. This includes firewalls, IDS/IPS systems, ACLs, and data encryption.
Provide security awareness training to all employees. This training should teach employees how to identify and avoid security threats.
Keep software and operating systems up to date. This will help to reduce the risk of security vulnerabilities being exploited.
Have a plan in place for responding to security incidents. This plan should include steps to contain the incident, eradicate the threat, and recover from the incident.

By taking these steps, NSSD can significantly reduce the risk of future security breaches and protect its data and systems from unauthorized access and modification.
