3.5 Assess and mitigate the vulnerabilities of security architectures, designs, and solution
elements
Malicious Code - What is the most commonly used technique to protect against virus
attacks?

operating system to allow the malicious code author to gain access to his files. What type of
exploit did this attacker engage in?
A Escalation of privilege
B Back door
C Rootkit
D Buffer overflow
Buffer Overflow
Buffer overflow attacks allow an attacker to modify the contents of a system's memory by
writing beyond the space allocated for a variable.
Domain 3: Security Architecture and Engineering
3.6 Assess and mitigate vulnerabilities in web-based systems
Application Attacks - What type of application vulnerability most directly allows an
attacker to modify the contents of a system's memory?
,A TOC/TOU
B Back door
C Rootkit
D Buffer overflow
Reflected Input
Cross-site scripting attacks are successful only against web applications that include
reflected input.

fsas3alG
Except option C, the choices are forms of common words that might be found during a
dictionary attack. mike is a name and would be easily detected. elppa is simply apple
spelled backward, and dayorange combines two dictionary words. Crack and other utilities
can easily see through these "sneaky" techniques. Option C is simply a random string of
characters that a dictionary attack would not uncover.
Domain 3: Security Architecture and Engineering

Password Attacks - Which one of the following passwords is least likely to be compromised
during a dictionary attack?
A elppa
B dayorange
C fsas3alG
D mike
