Marriott International Data Breach: Network Security Analysis
This paper analyzes the Marriott International data breach, widely considered one of the largest corporate security failures in history, in which hackers gained unauthorized access to the Starwood guest reservation database for approximately four years and compromised data on 500 million guests. The paper reviews the network security practices in place at the time of the breach, identifies key contributing factors — including inadequate security infrastructure inherited during the Starwood merger and the absence of real-time intrusion alerts — and proposes a plan of action centered on intrusion detection and prevention systems. Additional preventive measures discussed include cyber risk monitoring, artificial intelligence-based threat detection, and stronger authentication protocols.

What makes this paper effective
- Grounds the analysis in a real, high-profile case study, giving abstract cybersecurity concepts concrete stakes and making the argument immediately relevant.
- Moves logically from diagnosis (what happened and why) to prescription (what should be done), giving the paper a clear cause-and-effect structure that is easy to follow.
- Balances technical specificity — naming AES-128 encryption, HIPS, and NIPS — with accessible explanation, making the paper readable without sacrificing accuracy.
Key academic technique demonstrated
The paper demonstrates applied case-study analysis: it uses a single, well-documented real-world incident as the lens through which to evaluate broader principles of network security. Rather than surveying cybersecurity theory in the abstract, the author anchors every claim — about vulnerabilities, recommended tools, and preventive strategies — to the documented facts of the Marriott breach, then cites industry sources to validate each proposed solution.
Structure breakdown
The paper opens with a brief contextualization of the cyber-threat landscape, then introduces the Marriott case and describes the network practices in place at the time of the breach. A dedicated section identifies the specific vulnerabilities that allowed the attack to succeed. Two subsequent sections shift from diagnosis to remedy: one outlines an immediate action plan (IDS/IPS implementation), and the other proposes longer-term preventive measures such as AI-based monitoring and stronger authentication. A short conclusion ties the lessons back to the broader business environment.
Introduction
Data breaches have become common in today's business environment as organizations are increasingly vulnerable to cyber-attacks. Jain and Ropple (2018) state that many companies and institutions face significant challenges in successfully managing cyber risk despite increased expenditures on network security. Even though some industry standards have been established, they remain relatively vague. Additionally, existing solutions for safeguarding organizations against data breaches are not entirely effective. Sophisticated criminal methods have compounded organizations' vulnerabilities to data breaches and cyber-attacks. This paper examines the recent data breach at Marriott International, a large American hotel chain. The evaluation discusses the existing telecommunication and network practices at the time of the breach, the factors that contributed to it, and a plan of action to alleviate those vulnerabilities.
