Module 5: Security Post-test

A biometric system is a method of identification that uses unique physical or behavioral characteristics of an individual to verify their identity. Fingerprinting is a common form of biometric identification where the ridges and patterns on a person's fingertip are scanned and compared to a database of known fingerprints to determine their identity. This method is widely used in various applications such as access control, law enforcement, and personal devices for secure authentication.

IEEE stands for the Institute of Electrical and Electronics Engineers. This organization is a professional association that focuses on advancing technology related to electrical and electronics engineering. They provide resources, publications, and networking opportunities for professionals in this field.

A government is supposed to aid in developing new standards by developing them as the need begins to arise. This means that the government should be proactive in identifying emerging needs and trends in various industries and sectors, and then take the necessary steps to establish standards that address these needs. Waiting until it is absolutely necessary or solely relying on big companies for guidance may result in delays and missed opportunities for the government to provide effective support and regulation in developing new standards. Therefore, developing standards as the need begins to arise ensures timely and relevant standards that can support innovation and growth.

A hashing algorithm is a method used to encrypt passwords. It takes an input (such as a password) and converts it into a fixed-size string of characters, which is typically a combination of letters and numbers. This encrypted string is then stored in a database instead of the actual password, providing an extra layer of security. When a user enters their password, it is hashed and compared to the stored hash to determine if it is correct. Therefore, a hashing algorithm is not a math equation or a cooking recipe, but rather a form of password encryption.

The password "12qw#$ER56ty&*UI" is the most secure because it includes a combination of uppercase and lowercase letters, numbers, and special characters. This makes it more difficult for hackers to guess or crack the password using brute force or dictionary attacks. The length of the password is also important, and "12qw#$ER56ty&*UI" is longer than the other options, providing an additional layer of security.

Multi-factor authentication is a type of authentication that requires multiple types of input. This means that in order to gain access to a system or account, the user must provide more than just a password. It typically involves a combination of something the user knows (such as a password), something the user has (such as a security token or smartphone), and something the user is (such as a fingerprint or facial recognition). This added layer of security helps to protect against unauthorized access and enhances the overall security of the system or account.

Wireless technology helps society by increasing communication. It allows people to connect and communicate with each other without the need for physical wires or cables. This enables easier and more convenient communication, as people can use wireless devices such as smartphones, laptops, and tablets to stay connected and share information. Wireless technology also provides greater mobility, as people can communicate and access the internet from anywhere within the range of a wireless network. Overall, wireless technology has revolutionized communication and made it more accessible and efficient for society.

The statement suggests that digital certifications on information assurance are not worth checking, implying that they are not reliable or trustworthy. However, the correct answer is False, indicating that this statement is incorrect. Therefore, the explanation is that digital certifications on information assurance are not a waste of time to check, implying that they are indeed valuable and should be verified.

The acronym C.I.A. stands for Confidentiality, Integrity, and Availability in terms of business relations. These three principles are essential for maintaining the security and privacy of sensitive information. Confidentiality ensures that only authorized individuals have access to the information, integrity ensures that the information is accurate and trustworthy, and availability ensures that the information is accessible and usable when needed. These principles form the foundation of a secure and reliable business relationship.

A site having a Certification Authority indicates that the site has undergone a verification process and has been issued a digital certificate. This certificate serves as proof that the site can be trusted with data because it ensures that the site's identity has been authenticated and that the data transmitted between the site and the user is encrypted and secure. The Certification Authority plays a crucial role in establishing trust and security in online transactions and communications.

Tunneling Protocol affects VPNs by allowing users to connect to the internet and establish a secure tunnel back to company resources. This means that users can access the company's internal network and resources remotely, while ensuring that the connection is encrypted and secure. This is especially useful for remote workers or employees who need to access company resources while on the go.

Data theft is illegal because it involves the invasion of privacy and infringes upon the rights of others. By stealing someone's data, an individual or organization gains unauthorized access to personal information, which violates the privacy of the data owner. Additionally, data theft can lead to various forms of harm, such as identity theft or financial loss, which further violates the rights of the affected individuals. Therefore, both invasion of privacy and invasion of other peoples' rights are valid reasons for the illegality of data theft.

The correct answer is A. #base$. In the IEEE 802.3 standard, the formula for ethernet cables is commonly referred to as "base". This formula specifies the physical and electrical characteristics of the cables used for Ethernet networks. The use of the # symbol and the $ symbol in the answer options is likely just a formatting choice and not directly related to the formula itself.

Fingerprinting is a very secure authentication method because no two individuals have the same fingerprints. The unique patterns and ridges on each person's fingers make it nearly impossible for someone to replicate or forge another person's fingerprints. This uniqueness ensures that only the authorized individual can access the system or device, making it a highly secure method of authentication.

The presence of anti-virus and anti-spyware on a computer does not guarantee complete safety. While these software can provide a certain level of protection against viruses and spyware, they are not foolproof. New threats are constantly emerging, and there is always a possibility that these security measures may not be able to detect or prevent them. It is important to regularly update the software and practice safe browsing habits to enhance overall security.

A confidentiality contract is necessary because workers may leak confidential details. This contract ensures that employees understand the importance of keeping sensitive information private and provides legal protection in case of any breaches. By signing a confidentiality agreement, employees are bound by contractual obligations to maintain confidentiality, preventing unauthorized disclosure of confidential information. This helps to safeguard sensitive data, trade secrets, and other valuable information from being shared or used inappropriately.

A VPN (Virtual Private Network) uses a tunneling protocol to allow users/workers to securely access the company's network from an outside source. This protocol creates a secure and encrypted connection between the user's device and the company's network, ensuring that data transmitted over the internet remains private and protected from unauthorized access. The tunneling protocol encapsulates the data packets within an outer packet, which is then transmitted through the public internet, creating a virtual "tunnel" for the data to travel through. This helps to maintain the confidentiality and integrity of the data while accessing the company's network remotely.

A VPN stands for Virtual Private Network. It is a technology that allows users to create a secure and encrypted connection over a public network, such as the internet. This enables users to access and transmit data privately and securely, as if they were directly connected to a private network. VPNs are commonly used by individuals and organizations to protect their sensitive information and maintain their privacy online.

Wireless connections are used when the distance between devices is too far for a wired connection. In such cases, it is not feasible or practical to lay down physical cables or wires to establish a connection. Wireless technology allows for communication and data transfer without the need for physical connections, making it a suitable option when the distance is too far for wired connections.

Using Tunneling Protocol offers both flexibility and scalability. Flexibility refers to the ability to adapt and customize the protocol to suit different network configurations and requirements. This allows for easier integration with existing systems and the ability to support various network protocols. Scalability, on the other hand, refers to the protocol's ability to handle increasing amounts of traffic and users without compromising performance. Tunneling Protocol can efficiently handle large amounts of data and can be easily scaled up to accommodate growing network demands. Therefore, the correct answer is C. Both A and B.

The need for data assurance has been on the rise due to both the increase in networks and the increasing number of people seeking access to data. With the expansion of networks, there are more opportunities for data breaches and security threats. Additionally, as more people are interested in obtaining data, the risk of unauthorized access or misuse of data increases. Therefore, the combination of these factors has led to a greater need for data assurance.

Wireless connections are less secure than wired connections because anyone within range can receive the signal, making it vulnerable to unauthorized access. Additionally, passwords used in wireless connections can be easily hacked, further compromising the security. Therefore, both factors contribute to the reduced security of wireless connections compared to wired ones.

False. A keylogger can both be downloaded and installed on a device without the user's knowledge or consent. Once installed, it can record all keystrokes made on the device, including passwords and sensitive information, and send them to a remote location. Therefore, it is important to have proper security measures in place to protect against keyloggers and regularly scan devices for any potential threats.

Non-repudiation refers to the concept that a site or system does not allow the validity of a transaction or communication to be disputed or denied. This means that once a user has performed a certain action or made a certain statement, they cannot later claim that they did not do so. Non-repudiation is important in ensuring accountability and trustworthiness in digital transactions and communications, as it prevents one party from falsely denying their involvement or actions.

IBM is a trusted certification because it is a well-known and reputable company in the field of technology and information technology. IBM offers various certifications in different areas such as cloud computing, cybersecurity, data science, and artificial intelligence. These certifications are recognized and respected by employers and professionals in the industry, indicating that individuals who hold an IBM certification have met certain standards of knowledge and expertise.

The statement is true because the Conficker Working Group is indeed in a well-known G.I.A. partnership.

Hashing algorithms are more secure because they are a type of encryption. Encryption is the process of converting data into a form that cannot be easily understood by unauthorized individuals. Hashing algorithms use mathematical functions to transform input data into a fixed-size string of characters, known as a hash value. This hash value is unique to each input, making it difficult to reverse-engineer the original data. Therefore, hashing algorithms provide a secure way to store and transmit sensitive information without revealing the actual data.

If employees disclose personal customer information, the appropriate action to be taken is to fire them. Disclosing personal customer information is a serious breach of trust and privacy, and it can have severe consequences for both the company and the affected customers. By firing the employees, the company sends a strong message that such behavior is unacceptable and will not be tolerated. This action helps to protect the company's reputation and maintain customer trust in their data security measures.

The correct answer is C. 802.11g. 802.11g is a wireless protocol that has a standard bandwidth of 54 Mbps. This protocol operates in the 2.4 GHz frequency range and is backward compatible with 802.11b. It provides faster data transfer speeds compared to 802.11b and is widely used in home and small office networks.

Being on a network is not a prerequisite for being affected by a network worm. Network worms can spread through various means, such as infected USB drives or malicious websites. Therefore, even if you are not on a network, you can still be affected by a network worm if you come into contact with it through other sources.

A government, industry, and academia partnership refers to representatives from these three sectors collaborating and working together. This collaboration involves sharing resources, knowledge, and expertise to address common goals, challenges, and opportunities. It promotes cooperation and synergy between the government, industry, and academia, leading to the development and implementation of innovative solutions, policies, and initiatives that benefit society as a whole.

The $ symbol in the formula #base refers to the maximum segment length. This means that the formula is used to calculate the maximum length of a segment in a network. The $ symbol is used as a placeholder in the formula to represent this maximum value.

An unaware user is the most unsafe factor for a computer because they are more likely to fall for scams, click on malicious links, or download infected files without realizing the potential risks. A user who is not knowledgeable about safe browsing habits or cybersecurity practices is more vulnerable to various online threats and can unknowingly expose their computer to malware, viruses, or other malicious activities.

802.11n is the correct answer because it is a wireless protocol that has a standard bandwidth of over 100 Mbps. In reality, it can achieve speeds of up to 128 Mbps, making it the protocol with the highest bandwidth among the options given. 802.11a and 802.11b have lower standard and actual bandwidths compared to 802.11n.

802.11n is the correct answer because it offers the highest data transfer rate or Mbps (Megabits per second) compared to 802.11b and 802.11g. While 802.11b has a maximum data rate of 11 Mbps and 802.11g has a maximum data rate of 54 Mbps, 802.11n can provide data rates up to 600 Mbps or even higher with the use of multiple antennas and other advanced techniques. Therefore, 802.11n is the wireless protocol with the highest Mbps.

802.11g has the highest bandwidth among the given options. This is because 802.11g operates on the 2.4 GHz frequency band and has a maximum data rate of 54 Mbps. On the other hand, 802.11a operates on the 5 GHz frequency band and has a maximum data rate of 54 Mbps, while 802.11b operates on the 2.4 GHz frequency band but has a maximum data rate of only 11 Mbps. Therefore, 802.11g provides the highest bandwidth among the three options.

A trojan horse virus activates when it is downloaded in a package automatically. This means that the virus is hidden within another file or program that is downloaded onto the computer. Once the package is downloaded and opened, the trojan horse virus is unleashed and can start causing damage to the system. It is important to be cautious when downloading files or programs from the internet to avoid inadvertently downloading a trojan horse virus.

Salted hashes are considered the most secure encryption method because they add an extra layer of protection to the hashing process. A salt is a random string of characters that is added to the plaintext before it is hashed. This makes it much more difficult for attackers to crack the hash through techniques like rainbow tables, as they would need to generate a separate rainbow table for each unique salt. Therefore, salted hashes provide stronger protection against password cracking and other attacks compared to hashing algorithms or Blowfish encryption alone.

The correct answer is C. 802.11b. The 802.11b wireless protocol has a standard bandwidth of 11 Mbps. This protocol operates in the 2.4 GHz frequency range and is one of the earlier versions of Wi-Fi. It provides a slower data transfer rate compared to newer protocols like 802.11n, but it is still commonly used for basic internet browsing and email on older devices.

Wireless G cannot penetrate a concrete, underground bunker because concrete is a dense material that blocks wireless signals. The thickness and composition of the concrete make it difficult for the wireless signal to pass through, resulting in poor or no connectivity inside the bunker.

The correct answer is C. 10baseT. 10baseT is the formula used for a cable that utilizes Twisted Pairs. Twisted Pair is a type of cable commonly used in Ethernet networks, where two conductors are twisted together to reduce electromagnetic interference. The "10base" prefix refers to the data transfer rate of the cable, which in this case is 10 megabits per second. Therefore, 10baseT is the appropriate formula for a cable that uses Twisted Pairs.

A network worm is considered the most dangerous among the options given because it has the ability to replicate itself and spread across a network without any user interaction. Once it infects a system, it can quickly spread to other connected devices, causing widespread damage and disruption. Network worms can also carry payloads that can further compromise security, such as stealing sensitive information or launching additional attacks. In comparison, a Trojan is a type of malware that appears harmless but can perform malicious actions once installed, and a keylogger is a specific type of malware that records keystrokes, potentially capturing sensitive information. However, neither of these options have the same potential for rapid and widespread damage as a network worm.

The correct answer is B. 10baseF. The formula for a Fiber Optic cable is typically represented as "baseF" which stands for "baseband fiber optic". This indicates that the cable is capable of transmitting digital signals using baseband modulation. The "10" in "10baseF" refers to the maximum transmission speed of 10 Mbps (megabits per second) for the cable.

The formula for a Coaxial cable is 10base2.

The # symbol in the formula #base$ refers to the highest transmission rate. It indicates the maximum speed at which data can be transmitted through a particular channel or network. This symbol is commonly used in formulas and calculations to represent the maximum or peak value of a variable. In the context of transmission rates, the # symbol signifies the fastest possible speed at which information can be transferred.

A digital signature is a way to verify the authenticity and integrity of digital documents or messages. It involves using cryptographic algorithms to create a unique digital fingerprint of the document or message, which can be verified by a trusted third party, such as a certificate authority. This ensures that the document or message has not been tampered with and originated from the claimed sender. In this context, option B is the correct answer as it correctly describes the purpose and role of a digital signature.

The correct answer is C. 802.11a.

The 802.11a wireless protocol has a standard bandwidth of 54 Mbps. However, in reality, it only has about a 2 Mbps bandwidth. This is because 802.11a operates on a higher frequency band (5 GHz) compared to other protocols like 802.11b and 802.11n, which operate on the 2.4 GHz band. The higher frequency band used by 802.11a allows for faster data transmission, but it also has a shorter range and is more susceptible to interference, resulting in a lower actual bandwidth.

During the hashing process, the larger data is broken down into smaller units called "Datum". This allows for easier processing and storage of the data. Each datum represents a smaller portion of the original data, making it more manageable for hashing algorithms to operate on.

The correct answer is B. 802.11a. The 802.11a wireless signal operates on the 5 GHz band.
