In Chapter 8, we discussed different defensive strategy tactics for STRIDE. Considering where you work now (if you do not work, then consider your last job). For each item in STRIDE, provide at least one example of how you would mitigate attacks at your workplace. Provide the following: 1. A brief definition of the threat (e.g., S in STRIDE stands for Spoofing). 2. An example of the threat at your job that you have experienced (or could have experience). 3. What was done to combat the threat (or what could be done if the threat arises). 4. Each threat should be at least 50 words or more to receive full credit (no graphics).

Paper For Above instruction

In Chapter 8, the discussion centered around STRIDE, a comprehensive model used to identify and mitigate security threats within an organizational context. Applying this framework to a real-world workplace scenario involves understanding each threat type within STRIDE—Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege—and developing strategic measures to address them effectively.

Spoofing

Spoofing refers to the act of impersonating another entity to gain unauthorized access or deceive users. It aims to forge identities or data to appear legitimate, thereby breaching authentication mechanisms. For example, at my previous workplace, I encountered an incident where an attacker impersonated the company's email address to send phishing emails requesting sensitive information. This threat exploited the trust users had in legitimate communications, leading to potential data breaches. To combat spoofing, the organization implemented email authentication protocols like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance). These measures verified email sources, making it difficult for attackers to successfully impersonate legitimate addresses. Additionally, staff education on recognizing suspicious emails was reinforced to prevent falling victim to spoofing attempts.

Tampering

Tampering involves malicious modifications to data or systems with the intent to cause harm or unauthorized changes. It includes altering code, data, or hardware components. A relevant example at my workplace was during routine software updates when a malicious insider attempted to modify configuration files to introduce a backdoor. Although the tampering was detected early, it highlighted the importance of access controls. To mitigate tampering, strict access controls and audit trails were implemented, ensuring only authorized personnel could modify critical systems. Regular integrity checks, such as file hashing and version control, helped detect unauthorized alterations promptly. Role-based access control (RBAC) minimized the risk by assigning permissions based on the least privilege principle, further reducing the likelihood of tampering perpetrated by internal or external actors.

Repudiation

Repudiation occurs when an individual denies having performed an action, which can undermine accountability and audit processes. An example from my experience involved an employee denying responsibility for unauthorized data deletion logs. The lack of proper audit trails made it difficult to prove accountability. To mitigate repudiation, implementing robust logging and audit trails is essential. In our organization, we adopted comprehensive logging mechanisms that recorded all user actions with timestamps and user identifiers. Digital signatures and non-repudiation technologies like secure logging ensured that users could not deny actions they performed. These measures enhanced accountability and allowed for thorough investigations in case of suspicious activities.

Information Disclosure

Information disclosure refers to exposing sensitive data to unauthorized individuals, leading to privacy violations or data breaches. At my previous job, a misconfigured database schema inadvertently exposed customer information via a web interface, risking unauthorized access. To address this, the organization applied encryption for data at rest and in transit, along with access controls limiting data exposure based on user roles. Regular vulnerability assessments and security patches were prioritized to prevent exploitation of known vulnerabilities. Additionally, data masking techniques were employed in user interface displays to prevent sensitive data from being seen by unauthorized personnel, thereby reducing information disclosure risk.

Denial of Service (DoS)

Denial of Service involves overwhelming systems with excessive traffic or requests, rendering services unavailable. For example, our company's online portal experienced a simulated DoS attack during a security exercise, which temporarily slowed response times. To counteract such threats, we employed traffic filtering, rate limiting, and intrusion detection systems to identify and block malicious traffic. Implementing redundant server architectures and load balancers ensured service availability even under attack conditions. Regular security monitoring enabled quick responses to potential DoS incidents, minimizing downtime and maintaining user trust.

Elevation of Privilege

Elevation of privilege occurs when a user gains higher access rights than authorized, potentially allowing malicious actions. In one instance, a junior employee exploited a vulnerability in the internal admin tool to escalate privileges and access sensitive data. To prevent this, the company enforced strict access controls, multi-factor authentication, and regular privilege audits. Patch management and vulnerability assessments were also continuous, reducing the likelihood of exploitation. By isolating administrative privileges and monitoring privileged account activities, the organization minimized the risk of unauthorized elevation and maintained a secure operational environment.
