Bob, a system administrator at TPNQM SA, concluded one day that a DMZ is not needed if he properly
configures the firewall to allow access just to servers/ports, which can have direct internet access, and

Email is transmitted across the Internet using the Simple Mail Transport Protocol. SMTP does not encrypt
email, leaving the information in the message vulnerable to being read by an unauthorized person. SMTP
can upgrade a connection between two mail servers to use TLS. Email transmitted by SMTP over TLS is
encrypted. What is the name of the command used by SMTP to transmit email over TLS?
A. OPPORTUNISTICTLS STARTTLS
B. FORCETLS
C. UPGRADETLS
Answer: B
You are monitoring the network of your organizations. You notice that:
* 1. There are huge outbound connections from your Internal Network to External IPs.
* 2. On further investigation, you see that the External IPs are blacklisted.
* 3. Some connections are accepted, and some are dropped.
* 4. You find that it is a CnC communication. Which of the following solution will you suggest?
A. Block the Blacklist IP’s @ Firewall
B. Update the Latest Signatures on your IDS/IPS
C. Clean the Malware which are trying to Communicate with the External Blacklist IP’s
D. Both B and C

Identify the web application attack where the attackers exploit vulnerabilities in dynamically generated web
pages to inject client-side script into web pages viewed by other users.
A. SQL injection attack
B. Cross-Site Scripting (XSS)
C. LDAP Injection attack
D. Cross-Site Request Forgery (CSRF)
Answer: B
Which of the following options represents a conceptual characteristic of an anomaly-based IDS over a
signature-based IDS?
A. Produces less false positives
B. Can identify unknown attacks
C. Requires vendor updates for a new threat
D. Cannot deal with encrypted network traffic
Answer: B
What is one of the advantages of using both symmetric and asymmetric cryptography in SSL/TLS?
A. Symmetric algorithms such as AES provide a failsafe when asymmetric methods fail.
B. Asymmetric cryptography is computationally expensive in comparison. However, it is well-suited to
securely negotiate keys for use with symmetric cryptography.
C. Symmetric encryption allows the server to securely transmit the session keys out-of-band.
D. Supporting both types of algorithms allows less-powerful devices such as mobile phones to use
symmetric encryption instead.
Answer: D

B. Cain & Abel
C. Nessus
D. Snort
Answer: D
In the field of cryptanalysis, what is meant by a “rubber-hose” attack?
A. Attempting to decrypt cipher text by making logical assumptions about the contents of the original plain
text.
B. Extraction of cryptographic secrets through coercion or torture.
C. Forcing the targeted key stream through a hardware-accelerated device such as an ASIC.
D. A backdoor placed into a cryptographic algorithm by its creator.
Answer: B
