In cybersecurity, what is an active attack?

• A. An attempt to observe data without interference
• B. A proactive measure to enhance security
• C. An effort to alter system resources or operations
• D. A passive collection of information

Answer: (C)

An active attack in the context of cybersecurity refers to an effort to alter system resources or operations. This type of attack involves an adversary taking direct steps to manipulate, destroy, or disrupt information and system processes, rather than merely observing or collecting data. Active attacks often aim to change the integrity or availability of systems and networks, which can include actions such as injecting malicious code, performing denial-of-service attacks, or altering data.

This understanding contrasts with passive attacks, which focus on eavesdropping or unauthorized monitoring of data flows without interference. Recognizing the differences between active and passive attacks is crucial for developing appropriate security measures and responses within an organization, as active attacks directly endanger the performance and reliability of systems and may lead to significant damage or loss of data integrity.
