What do attack-signature-detection tools focus on identifying?

1. Unusual network traffic

2. Specific sequences of unauthorized access attempts

3. Trends in system performance

4. Data loss incidents

The correct answer is: Specific sequences of unauthorized access attempts

Attack-signature-detection tools are specifically designed to identify patterns that match known attack signatures. These signatures are predefined characteristics or patterns of malicious activity, such as unique sequences of commands or data that are typically used during unauthorized access attempts. By recognizing these specific sequences, the tools can effectively alert security personnel to potential intrusions or attacks, allowing for a prompt response to mitigate threats. The emphasis on identifying specific unauthorized access attempts distinguishes this approach from broader monitoring techniques. For instance, while unusual network traffic could be a sign of an attack, it is not as definitive as recognizing a known attack signature. Similarly, trends in system performance and data loss incidents are commonly monitored for overall system health and security but do not directly relate to the identification of specific attack attempts. Therefore, focusing on specific unauthorized access attempts aligns precisely with the functionality of attack-signature-detection tools.
