IT Security Vulnerabilities and Solutions for Organizations
This paper examines the major categories of IT security vulnerabilities that organizations face and proposes corresponding solutions for each. Drawing primarily on Gerhard Eschelbeck's research and the RAND Vulnerability Assessment and Mitigation Methodology, the paper identifies three generations of external threats — from early macro viruses to fast-propagating worms — alongside internal, physical, cyber, and human/social vulnerabilities. For each threat category, the paper outlines practical countermeasures including antivirus maintenance, network auditing, patch management, firewalls, standardized cyber-threat language, and employee training programs. The discussion highlights the evolving complexity of information security risks and the need for layered, continuously updated defenses.

What makes this paper effective
- Consistently applies a problem-solution structure, making each vulnerability category easy to follow and directly actionable.
- Draws on credible sources, including congressional testimony by Gerhard Eschelbeck and a RAND Institute methodology report, lending academic authority to the arguments.
- Covers a broad spectrum of threat types — external, internal, physical, cyber, and social — giving the paper comprehensive scope without losing focus.
Key academic technique demonstrated
The paper demonstrates effective use of a parallel organizational pattern: each major section introduces a problem category, defines its subtypes with examples, and then prescribes solutions. This pattern helps readers compare threat categories systematically and shows the student's ability to apply a consistent analytical framework across diverse subject matter.
Structure breakdown
The paper opens with a brief contextual introduction establishing the growing importance of IT security. It then alternates between problem and solution sections twice — first for external/internal vulnerabilities, then for physical, cyber, and human/social vulnerabilities. Each problem section uses subcategories and real-world examples (e.g., Melissa virus, SQL Slammer worm), while each solution section maps countermeasures directly to the threats described. The bibliography and footnotes are consistently formatted throughout.
Introduction
In the past, the worst threat to an information system was a natural disaster capable of destroying all stored data. Today, however, the category of risks has become thoroughly diversified. Because of the increasing use of information systems as data storage and processing tools, it has become ever more important to provide suitable solutions for each type of threat. This paper presents a series of problems one may face when ensuring IT security in an organization, together with a set of corresponding solutions. Both external and internal vulnerabilities are addressed, as well as cyber, physical, and social ones.
