Third Flashcards
Steve, a scientist who works in a governmental security agency, developed a technological solution to identify people based on walking patterns and implemented this approach to a physical control access. A camera captures people walking and identifies the individuals using Steve’s approach. After that, people must approximate their RFID badges. Both the identifications are required to open the door.
In this case, we can say:
The solution implements the two authentication factors: physical object an physical characteristic
Which Intrusion Detection System is the best applicable for large environments where critical assets on the network need extra scrutiny and is ideal for observing sensitive network segments?
Network-based intrusion detection system (NIDS)
Which of the following is a serious vulnerability in the popular OpenSSL cryptographic software library? This weakness allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure the Internet.
Heartbleed Bug
Which protocol is used for setting up secure channels between two devices, typically in VPNs?
IPSEC
Which of the following Secure Hashing Algorithm (SHA) produces a 160-bit digest from a message with a maximum length of (264-1) bits and resembles the MD5 algorithm?
SHA-1
When does the Payment Card Industry Data Security Standard (PCI-DSS) require organizations to perform external and internal penetration testing?
At least once a year and after any significant upgrade or modification.
If a tester is attempting to ping a target that exists but receives no response or a response that states the destination is unreachable, ICMP may be disabled and the network may be using TCP. Which other option could the tester use to get a response from a host using TCP?
HPing
Which of the following types of jailbreaking allows user-level access but does not allow iboot-level access?
Userland exploit
What is not a PCI compliance recommendation?
Rotate employees handling credit card transactions on a yearly basis to different departments.
The “white box testing” methodology enforces what kind of restriction?
The internal operation of a system is completely known to the tester.
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.
Cross-Site Scripting (XSS)
This tool is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, as well as the PTW attack, thus making the attack much faster compared to other WEP cracking tools. Which of the following tools is being described?
Aircrack-ng

Port scan targeting 192.168.0.110
You are attempting to run an Nmap port scan on a web server. Which of the following commands would result in a scan of common ports with the least amount of noise in order to evade IDS?
nmap -sT -O -T0
Bob, your senior colleague, has sent you a mail regarding aa deal with one of the clients. You are requested to accept the offer and you oblige.
After 2 days, Bob denies that he had ever sent a mail.
What do you want to “know” to prove yourself that it was Bob who had send a mail?
Non-repudation
