IT System Connection Table CMGT/430 Version 5 University of Phoenix Material IT System Connection Table When securing the modern enterprise, consider that IT systems do not operate alone. Securing them involves securing their interfaces with other systems as well. It is important to know the different interconnections each system may have. Fill out the following table for four different IT systems. · Note two enterprise systems they connect with and their connection type. · Note two security vulnerabilities the connection may have and 2 to 4 ways each vulnerability could be potentially exploited. Some Comments: · An example row has been entered into the table. · Keep in mind that enterprise systems cover a certain task in the enterprise (HR, CRM, Identity Management, etc.). They are not the components of a system (such as servers). · Connections can often be a direct connection/pipe, a file, a common database or something else. · The vulnerability is what would make the connection vulnerable to an attack. · The related risk is an attack that could target the weakness.

Paper For Above instruction

The security of enterprise IT systems is a critical concern for modern organizations. These systems are interconnected with various other platforms within the enterprise, creating potential vulnerabilities that malicious actors could exploit. Identifying these interconnections, understanding their vulnerabilities, and assessing associated risks are crucial steps in developing a robust cybersecurity strategy. This paper explores four different enterprise IT systems, their connection types with other systems, their vulnerabilities, and the potential exploits that could threaten organizational assets. Through this analysis, best practices for securing these connected systems are outlined to mitigate risks effectively.

Introduction

Enterprise systems such as Human Resources (HR), Customer Relationship Management (CRM), finance, and identity management play vital roles in organizational operations. These systems require integration with other systems for data sharing, process automation, and operational efficiency. However, these connections introduce vulnerabilities that can be exploited to compromise sensitive data, disrupt operations, or gain unauthorized access. Therefore, understanding the nature of these connections and their security implications is imperative for safeguarding enterprise IT infrastructure.

Enterprise IT Systems, Connections, Vulnerabilities, and Risks

1. Human Resources (HR) System

  • Connected Systems: Identity Management System, Payroll System
  • Connection Types: Feeder Files, API Integration
  • Potential Vulnerabilities:
  • Data modification during transfer (e.g., files could be altered in transit)
  • Unauthorized access via API exploits (e.g., injection attacks or weak authentication)
  • Potential Exploits:
  • People with malicious intent could modify HR data, leading to incorrect employee records or payroll errors.
  • Attackers could leverage API vulnerabilities to access sensitive personnel information or escalate privileges.

2. Customer Relationship Management (CRM) System

  • Connected Systems: Marketing System, Sales Database
  • Connection Types: Direct Database Connection, REST API
  • Potential Vulnerabilities:
  • SQL Injection via poorly secured database connections
  • Intercepted API requests revealing sensitive customer data
  • Potential Exploits:
  • Malicious actors could exploit SQL injection to manipulate or extract customer data.
  • Interception of API data could lead to customer identity theft or competitive intelligence theft.

3. Financial System (Finance Accounting)

  • Connected Systems: Banking Institutions, Audit Software
  • Connection Types: Secure File Transfer Protocol (SFTP), Encrypted APIs
  • Potential Vulnerabilities:
  • File transfer interception or tampering due to lapses in encryption
  • Insider threats exploiting access privileges to modify financial data
  • Potential Exploits:
  • Attackers could intercept financial data during transfer, leading to fraud or data breaches.
  • Malicious insiders might alter or delete financial records, resulting in accounting fraud.

4. Identity Management System

  • Connected Systems: HR System, Access Control Systems
  • Connection Types: LDAP Protocol, Secure API
  • Potential Vulnerabilities:
  • Weak LDAP authentication allowing unauthorized access
  • APIs exposing user credentials due to poor security policies
  • Potential Exploits:
  • External attackers might bypass identity controls to access restricted areas.
  • Credential theft via API exploits could lead to lateral movement within the network.

Conclusion

Securing enterprise IT systems requires comprehensive understanding of their interconnections, vulnerabilities, and associated risks. Each connection point, whether through files, APIs, or direct database links, presents potential avenues for cyberattacks. Implementing strong access controls, encrypting data in transit, and regularly monitoring system activities are essential measures. Additionally, conducting regular vulnerability assessments and staff training further enhance security resilience. Organizations must adopt a layered security approach to protect interconnected systems from evolving cyber threats, ensuring business continuity and safeguarding sensitive information.
