NEW QUESTION 223
what is the port to block first in case you are suspicious that an loT device has been compromised?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
Explanation
TCP port 48101 uses the Transmission management Protocol. transmission control protocol is one in all the most protocols in TCP/IP networks. transmission control protocol could be a connection-oriented protocol, it needs acknowledgement to line up end-to-end communications. only a association is about up user's knowledge may be sent bi-directionally over the association.
Attention! transmission control protocol guarantees delivery of knowledge packets on port 48101 within the same order during which they were sent. bonded communication over transmission control protocol port
48101 is that the main distinction between transmission control protocol and UDP. UDP port 48101 wouldn't have bonded communication as transmission control protocol.
UDP on port 48101 provides Associate in Nursing unreliable service and datagrams might arrive duplicated, out of order, or missing unexpectedly. UDP on port 48101 thinks that error checking and correction isn't necessary or performed within the application, avoiding the overhead of such process at the network interface level.
UDP (User Datagram Protocol) could be a borderline message-oriented Transport Layer protocol (protocol is documented in IETF RFC 768).
Application examples that always use UDP: vocalisation IP (VoIP), streaming media and period multiplayer games. several internet applications use UDP, e.g. the name System (DNS), the Routing info Protocol (RIP), the Dynamic Host Configuration Protocol (DHCP), the straightforward Network Management Protocol (SNMP).

NEW QUESTION 225
There have been concerns in your network that the wireless network component is not sufficiently secure. You perform a vulnerability scan of the wireless network and find that it is using an old encryption protocol that was designed to mimic wired encryption, what encryption protocol is being used?
- A. WPA3
- B. RADIUS
- C. WEP
- D. WPA
Answer: D
Explanation:
Explanation
Wi-Fi Protected Access (WPA), Wi-Fi Protected Access II (WPA2), and Wi-Fi Protected Access 3 (WPA3) are the three security and security certification programs developed by the Wi-Fi Alliance to secure wireless computer networks. The Alliance defined these in response to serious weaknesses researchers had found within the previous system, Wired Equivalent Privacy (WEP).WPA (sometimes mentioned because the draft IEEE 802.11i standard) became available in 2003. The Wi-Fi Alliance intended it as an intermediate measure in anticipation of the supply of the safer and sophisticated WPA2, which became available in 2004 and may be a common shorthand for the complete IEEE 802.11i (or IEEE 802.11i-2004) standard.In January 2018, Wi-Fi Alliance announced the discharge of WPA3 with several security improvements over WPA2.The Wi-Fi Alliance intended WPA as an intermediate measure to require the place of WEP pending the supply of the complete IEEE 802.11i standard. WPA might be implemented through firmware upgrades on wireless network interface cards designed for WEP that began shipping as far back as 1999. However, since the changes required within the wireless access points (APs) were more extensive than those needed on the network cards, most pre-2003 APs couldn't be upgraded to support WPA.The WPA protocol implements much of the IEEE
802.11i standard. Specifically, the Temporal Key Integrity Protocol (TKIP) was adopted for WPA. WEP used a 64-bit or 128-bit encryption key that has got to be manually entered on wireless access points and devices and doesn't change. TKIP employs a per-packet key, meaning that it dynamically generates a replacement
128-bit key for every packet and thus prevents the kinds of attacks that compromised WEP.WPA also includes a Message Integrity Check, which is meant to stop an attacker from altering and resending data packets. This replaces the cyclic redundancy check (CRC) that was employed by the WEP standard. CRC's main flaw was that it didn't provide a sufficiently strong data integrity guarantee for the packets it handled. Well-tested message authentication codes existed to unravel these problems, but they required an excessive amount of computation to be used on old network cards. WPA uses a message integrity check algorithm called TKIP to verify the integrity of the packets. TKIP is far stronger than a CRC, but not as strong because the algorithm utilized in WPA2. Researchers have since discovered a flaw in WPA that relied on older weaknesses in WEP and therefore the limitations of the message integrity code hash function, named Michael, to retrieve the keystream from short packets to use for re-injection and spoofing.

NEW QUESTION 245
Harry. a professional hacker, targets the IT infrastructure of an organization. After preparing for the attack, he attempts to enter the target network using techniques such as sending spear-phishing emails and exploiting vulnerabilities on publicly available servers. Using these techniques, he successfully deployed malware on the target system to establish an outbound connection. What is the APT lifecycle phase that Harry is currently executing?
- A. Cleanup
- B. initial intrusion
- C. Persistence
- D. Preparation
Answer: B
Explanation:
After the attacker completes preparations, subsequent step is an effort to realize an edge within the target's environment. a particularly common entry tactic is that the use of spearphishing emails containing an internet link or attachment. Email links usually cause sites where the target's browser and related software are subjected to varied exploit techniques or where the APT actors plan to social engineer information from the victim which will be used later. If a successful exploit takes place, it installs an initial malware payload on the victim's computer. Figure 2 illustrates an example of a spearphishing email that contains an attachment. Attachments are usually executable malware, a zipper or other archive containing malware, or a malicious Office or Adobe PDF (Portable Document Format) document that exploits vulnerabilities within the victim's applications to ultimately execute malware on the victim's computer. Once the user has opened a malicious file using vulnerable software, malware is executing on the target system. These phishing emails are often very convincing and difficult to differentiate from legitimate email messages. Tactics to extend their believability include modifying legitimate documents from or associated with the organization. Documents are sometimes stolen from the organization or their collaborators during previous exploitation operations. Actors modify the documents by adding exploits and malicious code then send them to the victims. Phishing emails are commonly sent through previously compromised email servers, email accounts at organizations associated with the target or public email services. Emails also can be sent through mail relays with modified email headers to form the messages appear to possess originated from legitimate sources. Exploitation of vulnerabilities on public-facing servers is another favorite technique of some APT groups. Though this will be accomplished using exploits for known vulnerabilities, 0-days are often developed or purchased to be used in intrusions as required .
