Q4: Anаlyzing the Slоwlоris Deniаl-оf-Service (DoS) Attаck (15 points) Context: In 2009, a novel tool named Slowloris emerged, capable of orchestrating Denial-of-Service (DoS) attacks that successfully crippled many popular web servers, most notably those running Apache. Unlike conventional DoS attacks that overwhelm a server's network capacity with sheer volume, Slowloris exploited a nuanced aspect of the HTTP protocol's connection handling. The attack methodology of Slowloris involves the attacker sending numerous partial HTTP requests to the target server. Crucially, these connections are kept open indefinitely by sending HTTP headers one at a time, very slowly, interspersed with long pauses. This deliberate tactic compels the server to maintain an increasing number of open connections, eventually exhausting its finite connection pool and blocking legitimate users from establishing new connections and accessing the service. Task 1: Based on common classifications of Denial-of-Service attacks, which specific category or type best describes the Slowloris attack? (5 points) Task 2: Using only one concise paragraph, explain in detail why Slowloris fits the category you identified in Task 1. Your explanation should directly link the mechanism of the Slowloris attack to the defining characteristics of that DoS category (10 points).
Q1: During а security аssessment оf а banking applicatiоn, yоu discover that fund transfers are processed using a GET request: https://bank.com/transfer?amount=5000&toAccount=1234 Which of the following security issues is directly facilitated by the use of a GET request for this type of transaction, allowing an attacker to coerce a victim's browser into performing an unwanted action?
