Garry is a network administrator in an organization. He uses SNMP to manage networked devices from a remote location. To manage nodes in the network, he uses MIB. which contains formal descriptions of all network objects managed by SNMP. He accesses the contents of MIB by using a web browser either by entering the IP address and Lseries.mlb or by entering the DNS library name and Lseries.mlb. He is currently retrieving information from an MIB that contains object types for workstations and server services. Which of the following types of MIB is accessed by Garry in the above scenario?

LNMIB2.MIB
WINS.MIB
DHCP.MIS
MIB_II.MIB

Correct answer: A

Explanation:

DHCP.MIB: Monitors network traffic between DHCP servers and remote hosts ¦ HOSTMIB.MIB: Monitors and manages host resources ¦ LNMIB2.MIB: Contains object types for workstation and server services ¦ MIBJI.MIB: Manages TCP/IP- based Internet using a simple architecture and system ¦ WINS.MIB: For the Windows Internet Name Service (WINS)

An attacker redirects the victim to malicious websites by sending them a malicious link by email. The link appears authentic but redirects the victim to a malicious web page, which allows the attacker to steal the victim's data. What type of attack is this?

Phishing
Vlishing
Spoofing
DDoS

Correct answer: A

Explanation:

https://en.wikipedia.org/wiki/PhishingPhishing is a type of social engineering attack often used to steal user data, including login credentials and credit card numbers. It occurs when an attacker, masquerading as a trusted entity, dupes a victim into opening an email, instant message, or text message. The recipient is then tricked into clicking a malicious link, which can lead to the installation of malware, the freezing of the system as part of a ransomware attack, or the revealing of sensitive information.An attack can have devastating results. For individuals, this includes unauthorized purchases, the stealing of funds, or identify theft.Moreover, phishing is often used to gain a foothold in corporate or governmental networks as a part of a larger attack, such as an advanced persistent threat (APT) event. In this latter scenario, employees are compromised in order to bypass security perimeters, distribute malware inside a closed environment, or gain privileged access to secured data.An organization succumbing to such an attack typically sustains severe financial losses in addition to declining market share, reputation, and consumer trust. Depending on the scope, a phishing attempt might escalate into a security incident from which a business will have a difficult time recovering.Incorrect answers:Vishing https://en.wikipedia.org/wiki/Voice_phishingVoice phishing, or vishing, is the use of telephony (often Voice over IP telephony) to conduct phishing attacks.DDoS https://en.wikipedia.org/wiki/Denial-of-service_attackA distributed denial-of-service (DDoS) attack is a malicious attempt to disrupt the normal traffic of a targeted server, service or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic.DDoS attacks achieve effectiveness by utilizing multiple compromised computer systems as sources of attack traffic. Exploited machines can include computers and other networked resources such as IoT devices.Spoofing https://en.wikipedia.org/wiki/Spoofing_attack In the context of information security, and especially network security, a spoofing attack is a situation in which a person or program successfully identifies as another by falsifying data, to gain an illegitimate advantage.
