This True or False quiz helps you judge claims about script attacks and why they can be unpredictable, so you practice spotting facts vs myths in network security. Choose how you play: go statement by statement or mix in quick random items . You'll sharpen recall and find gaps in minutes.

Script attacks like Cross-Site Scripting (XSS) are always predictable.
True
False
Script attacks such as XSS exploit different contexts and payloads, making each attack scenario unique and often unpredictable. Variations in application code, user input points, and encoding techniques contribute to this unpredictability. Even minor changes in parameters or response handling can yield entirely different attack vectors. .
Script attacks exploit vulnerabilities in web applications.
True
False
Script attacks target security flaws in web applications to inject or execute malicious scripts. These vulnerabilities often arise from improper input validation or output encoding. By exploiting such weaknesses, attackers can hijack sessions, steal data, or redirect users. .
Validating user input on the server side can help prevent script attacks.
False
True
Server-side input validation ensures that malicious payloads are caught before processing or rendering. While client-side validation can be bypassed, server-side checks provide a reliable barrier. Combining both validation methods greatly reduces attack surfaces. .
Script attacks can only exploit poorly written JavaScript.
False
True
Script attacks leverage any weakness in how code is handled, not just poor JavaScript. Vulnerabilities in HTML, CSS, or browser APIs can also be abused. Attackers exploit logic errors, misconfigurations, and improper sanitization across the entire stack. .
Content Security Policy (CSP) can mitigate the impact of script attacks.
False
True
CSP allows administrators to define trusted sources for scripts and other resources. This reduces the risk of loading unauthorized or malicious code. However, misconfigured policies can leave gaps. .
Script attacks cannot bypass HTTP-only cookies.
True
False
HTTP-only cookies are inaccessible to JavaScript, reducing the risk of theft via XSS. However, script attacks can still trigger actions using those cookies, like authenticated requests. Attackers may leverage CSRF or other techniques in conjunction with script attacks. .
Reflective XSS requires malicious scripts to be stored on the server before triggering.
False
True
Reflective XSS occurs when user-supplied code is immediately returned by the server in the response. It does not require script storage on the server. Instead, the payload is reflected back through URL parameters or form inputs. .
Script attacks are always detectable by standard antivirus software.
False
True
Standard antivirus solutions focus on known malware signatures and binary threats. Many script attacks exploit runtime environments in browsers and servers dynamically, with no static signatures. Advanced or zero-day scripts often evade traditional detection. .
Script attacks involving DOM-based XSS rely solely on client-side code to inject payloads.
True
False
DOM-based XSS occurs when the vulnerability exists in client-side scripts handling data without proper sanitization. The payload is injected and executed entirely in the browser's DOM. The server is unaware of the malicious content. .
Subresource Integrity (SRI) completely eliminates the risk of supplying malicious external scripts.
True
False
SRI ensures that externally loaded scripts match a known cryptographic hash, preventing tampering. However, if the original script source is compromised or the hash isn't updated correctly, risk remains. It also doesn't guard against compromised inline scripts. .

Study Outcomes

  1. Analyze Script Attack Predictability -

    Interpret whether attacks conducted by scripts are usually unpredictable by evaluating key behaviors and patterns of automated threats.

  2. Evaluate DoS Attack Targets -

    Assess the statement that dos attacks cannot be launched against routers to understand real-world disruption tactics.

  3. Differentiate Fact from Fiction -

    Distinguish true versus false network security questions in this network security true false quiz to spot common misconceptions.

  4. Apply Critical Assessment Skills -

    Utilize critical thinking to challenge assertions about network vulnerabilities in a true false quiz format.

  5. Reinforce Key Security Concepts -

    Solidify your understanding of automated threats and denial-of-service tactics through targeted quiz questions.

  6. Boost Security Confidence -

    Gain confidence in identifying and responding to unpredictable script attacks and DoS scenarios in professional settings.

Cheat Sheet

  1. Predictability of Script Attacks -

    Although many believe that attacks conducted by scripts are usually unpredictable, security research (SANS Institute) shows they often follow identifiable patterns like fixed delays or signature payloads. Familiarize yourself with randomization techniques such as jitter timers to recognize when an exploit is mimicking unpredictability. This understanding demystifies the myth that script attacks are always random.

  2. Automated Exploitation Frameworks -

    Tools like Metasploit or sqlmap demonstrate how automation streamlines vulnerability scanning but introduces signature traits - like consistent user-agent strings - that defenders can spot (OWASP). When preparing for a network security true false quiz, recall that these frameworks use repeatable modules rather than pure randomness. Recognizing these traits helps turn unpredictability into pattern analysis.

  3. DoS Attacks on Routers: Myth Debunked -

    The statement that dos attacks cannot be launched against routers is false; devices with TCP/IP stacks like Cisco routers can be targeted with ICMP floods or TCP SYN storms (Cisco, NIST). Routers have resource constraints - CPU, memory, routing tables - that attackers exploit to degrade network performance. Keep in mind "Every device counts" as a mnemonic to recall that any IP-enabled hardware is vulnerable.

  4. Key Traits of Script-Based Threats (PRO) -

    Script attacks often leverage Polymorphism, Randomization, and Obfuscation - remember the "PRO" mnemonic to review these three tactics quickly (Symantec Labs). By associating each letter with a trait, you retain core characteristics essential for true false network security questions. This cheat-sheet approach boosts recall under test conditions.

  5. Strategic Approach to Network Security Quiz -

    When tackling a network security quiz, watch for absolutes like "always" or "never" and verify if exceptions exist according to NIST or academic sources. Use elimination: mark statements true only if no counterexample (e.g., some routers are susceptible to DoS). This disciplined method transforms guesswork into informed reasoning.
