The vulnerability that may affect the website according to the severity factor is FTP Unencrypted Cleartext Login, which has a medium severity level. FTP Unencrypted Cleartext Login is a vulnerability that allows an attacker to intercept or sniff FTP login credentials that are sent in cleartext over an unencrypted connection. An attacker can use these credentials to access or modify files or data on the FTP server. TCP timestamps and UDP timestamps are vulnerabilities that allow an attacker to estimate the uptime of a system or network by analyzing the timestamp values in TCP or UDP packets. Anonymous FTP Login Reporting is a vulnerability that allows an attacker to access an FTP server anonymously without providing any username or password.
An organization's risk management team identified the risk of natural disasters in the organization's current location. Because natural disasters cannot be prevented using security controls, the team suggested to build a new office in another location to eliminate the identified risk. Identify the risk treatment option suggested by the risk management team in this scenario.
Correct Answer:B
Risk avoidance is the risk treatment option suggested by the risk management team in this scenario. Risk avoidance is a risk treatment option that involves eliminating the identified risk by changing the scope, requirements, or objectives of the project or activity. Risk avoidance can be used when the risk cannot be prevented using security controls or when the risk outweighs the benefits2. References: Risk Avoidance
Martin, a network administrator at an organization, received breaching alerts for an application. He identified that a vulnerability in the application allowed attackers to enter malicious input. Martin evaluated the threat severity and extent of damage that could be caused by this vulnerability. He then escalated the issue to the security management team to determine appropriate mitigation strategies. In which of the following threat-modeling steps did Martin evaluate the severity level of the threat?
Correct Answer:C
Risk and impact analysis is the threat-modeling step in which Martin evaluated the severity level of the threat in the above scenario. Threat modeling is a process that involves identifying, analyzing, and mitigating threats and risks to a system or network. Threat modeling can be used to improve the security and resilience of a system or network by applying various methods or techniques, such as STRIDE, DREAD, PASTA, etc. Threat modeling consists of various steps or phases that perform different tasks or roles. Risk and impact analysis is a threat-modeling step that involves assessing the likelihood and consequences of threats and risks to a system or network . Risk and impact analysis can be used to evaluate the severity level of threats and risks and prioritize them for mitigation . In the scenario, Martin received breaching alerts for an application. He identified that a vulnerability in the application allowed attackers to enter malicious input. Martin evaluated the threat severity and extent of damage that could be caused by this vulnerability. He then escalated the issue to the security management team to determine appropriate mitigation strategies. This means that he performed risk and impact analysis for this purpose. Identify vulnerabilities is a threat-modeling step that involves finding and documenting the weaknesses or flaws in a system or network that can be exploited by threats or risks . Application overview is a threat-modeling step that involves defining and understanding the scope, architecture, components, and functionality of a system or network . Decompose the application is a threat-modeling step that involves breaking down a system or network into smaller and simpler elements, such as data flows, processes, assets, etc.
Charlie, a security professional in an organization, noticed unauthorized access and eavesdropping on the WLAN. To thwart such attempts, Charlie employed an encryption mechanism that used the RC4 algorithm to encrypt information in the data link layer. Identify the type of wireless encryption employed by Charlie in the above scenario.
Correct Answer:B
WEP is the type of wireless encryption employed by Charlie in the above scenario. Wireless encryption is a technique that involves encoding or scrambling the data transmitted over a wireless network to prevent unauthorized access or interception. Wireless encryption can use various algorithms or protocols to encrypt and decrypt the data, such as WEP, WPA, WPA2, etc. WEP (Wired Equivalent Privacy) is a type of wireless encryption that uses the RC4 algorithm to encrypt information in the data link layer
. WEP can be used to provide basic security and privacy for wireless networks, but it can also be easily cracked or compromised by various attacks . In the scenario, Charlie, a security professional in an organization, noticed unauthorized access and eavesdropping on the WLAN (Wireless Local Area Network). To thwart such attempts, Charlie employed an encryption mechanism that used the RC4 algorithm to encrypt information in the data link layer. This means that he employed WEP for this purpose. TKIP (Temporal Key Integrity Protocol) is a type of wireless encryption that uses the RC4 algorithm to encrypt information in the data link layer with dynamic keys . TKIP can be used to provide enhanced security and compatibility for wireless networks, but it can also be vulnerable to certain attacks . AES (Advanced Encryption Standard) is a type of wireless encryption that uses the Rijndael algorithm to encrypt information in the data link layer with fixed keys . AES can be used to provide strong security and performance for wireless networks, but it can also require more processing power and resources . CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) is a type of wireless encryption that uses the AES algorithm to encrypt information in the data link layer with dynamic keys .
CCMP can be used to provide robust security and reliability for wireless networks, but it can also require more processing power and resources
An FTP server has been hosted in one of the machines in the network. Using Cain and Abel the attacker was able to poison the machine and fetch the FTP credentials used by the admin. You're given a task to validate the credentials that were stolen using Cain and Abel and read the file flag.txt
Correct Answer:C
hat@red is the FTP credential that was stolen using Cain and Abel in the above scenario. FTP (File Transfer Protocol) is a protocol that allows transferring files between a client and a server over a network. FTP requires a username and a password to authenticate the client and grant access to the server . Cain and Abel is a tool that can perform various network attacks, such as ARP poisoning, password cracking, sniffing, etc. Cain and Abel can poison the machine and fetch the FTP credentials used by the admin by intercepting and analyzing the network traffic . To validate the credentials that were stolen using Cain and Abel and read the file flag.txt, one has to follow these steps:
✑ Navigate to the Documents folder of Attacker-1 machine.
✑ Double-click on Cain.exe file to launch Cain and Abel tool.
✑ Click on Sniffer tab.
✑ Click on Start/Stop Sniffer icon.
✑ Click on Configure icon.
✑ Select the network adapter and click on OK button.
✑ Click on + icon to add hosts to scan.
✑ Select All hosts in my subnet option and click on OK button.
✑ Wait for the hosts to appear in the list.
✑ Right-click on 20.20.10.26 (FTP server) and select Resolve Host Name option.
✑ Note down the host name as ftpserver.movieabc.com
✑ Click on Passwords tab.
✑ Click on + icon to add items to list.
✑ Select Network Passwords option.
✑ Select FTP option from Protocol drop-down list.
✑ Click on OK button.
✑ Wait for the FTP credentials to appear in the list.
✑ Note down the username as hat and the password as red
✑ Open a web browser and type ftp://hat:red@ftpserver.movieabc.com
✑ Press Enter key to access the FTP server using the stolen credentials.
✑ Navigate to flag.txt file and open it.
