Information Security

The primary goal of encryption is to secure data so that only those with the correct authorization (the key) can access and read the original information.

Asymmetric encryption (public-key cryptography) uses a pair of keys (public and private) to provide security services like authentication and confidentiality.

Symmetric encryption uses the same secret key for both encryption and decryption. The statement is false because it implies a specific type of key usage that is often contrasted with asymmetric encryption.

Encryption does not prevent the interception of data; it only ensures that the intercepted data remains unreadable to unauthorized parties. The question is poorly phrased, but option A correctly identifies what encryption fails to stop.

Encryption is defined as the process of encoding information to prevent unauthorized access. The other options are unrelated concepts.

Human error is widely recognized as the leading cause of security failures, including those related to encryption implementation and key management. The other options are clearly incorrect distractors.

The standard ethical hacking methodology begins with reconnaissance (information gathering) to identify targets and vulnerabilities before proceeding to scanning and exploitation.

Keylogging is the act of recording the keys struck on a keyboard, typically in a covert manner. This allows the attacker to capture passwords and other sensitive data.

A firewall acts as a barrier between a trusted internal network and untrusted external networks. Its primary purpose is to control traffic and prevent unauthorized access.

IPS stands for Intrusion Prevention System. It is a network security/threat prevention technology that examines network traffic flows to detect and prevent vulnerability exploits.

Enumeration involves actively interacting with the target system to gather detailed information such as user accounts, shared resources, and network topology. This phase typically follows initial network scanning during a security assessment.

A proxy server acts as an intermediary for requests from clients seeking resources from other servers. Hackers use them to mask their true IP address and hide their identity during attacks.

Cain and Abel is a well-known password recovery tool for Microsoft Windows operating systems. It can recover various types of passwords by sniffing the network or cracking encrypted passwords.

White Hat hackers are ethical hackers who use their skills to improve security by finding vulnerabilities and reporting them to the owners, rather than exploiting them for malicious gain.
