Abey, a software developer, is working on a prestigious project. John, a
colleague of Abey, is a disgruntled employee in the same company. John, with
malicious intent, decides to access confidential information regarding the
project, which Abey is sharing with the higher management. For this purpose,
he uses sniffing programs and captures the traffic originating from Abey's
system. As a result, he is able to obtain crucial project details.
,Identify the information assurance principle on which John has performed the
attack in the above scenario. Answer - Confidentiality
Which of the following network defense techniques examines the causes for
attacks in networks by using fault-finding mechanisms, security forensics
techniques, and post-mortem analysis? Answer - Retrospective Approach

information passing through the network and preserves the privacy and
reliability of the data? Answer - Encryption and Protocols
Which of the following components of technical network security controls
examines the network devices and identifies weaknesses in the network?
Answer - Auditing
Bob has recently purchased a new laptop and enabled all the required security
controls. The next day while verifying whether all the security mechanisms
were enabled on his system or not, he found that the "firewall" was disabled.
He immediately enabled the firewall option on his laptop.
Identify the component of technical security controls that Bob enabled to
protect his laptop from network-related threats. Answer - Network security
devices

TACACS+ authentication involves the following steps:
1.) The router and the user exchange authentication parameters
2.) The server responds with the REPLY message based on the provided
information
3.) A user initiates the connection for authentication
4.) The router sends the parameters to the server for authentication
I
dentify the correct order of steps involved. Answer - 3-1-4-2
, Which of the following protocols provides centralized authentication,
authorization, and accounting (AAA) for remote access servers to communicate
with a central server? Answer - RADIUS
Which of the following protocols is an application layer protocol used for
sending digitally signed and encrypted email messages? Answer - S/MIME
Margaret, a system administrator, regularly administers the devices connected
to the organizational network. She found that certain devices are vulnerable to
sniffing attacks. To protect the device from such attacks, Margaret employed a
protocol that encrypts the entire communication between the client and the
server, including the user's password, which protects it from sniffing attacks.
Identify the protocol employed by Margaret in the above scenario. Answer -
TACACS+
Benson, a security professional plans to implement more stringent security
practices in his organization. For this reason, he uses a protocol that provides
cryptographic security by encrypting the email messages and digitally signing
them to ensure confidentiality, integrity, and nonrepudiation of messages.
Which of the following protocols was employed by Benson in the above
scenario? Answer - S/MIME
James, a software engineer, is working from a remote location and connects his
laptop to the company's server through a VPN. The company has implemented
a security protocol that provides authentication as well as encryption of the
data passing through the VPN tunnels.
Identify the network security protocol implemented by the company for secure
communication. Answer - IPsec
