  2. To prevent malware and viruses from infecting the website

  3. To protect customer data from unauthorized access

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Firewalls play a crucial role in securing e-commerce websites by blocking unauthorized access to the website, preventing malware and viruses from infecting the website, and protecting customer data from unauthorized access.

Multiple choice

What is the primary goal of optimization in signature-based intrusion detection?

  1. Maximizing Detection Rate

  2. Minimizing False Positives

  3. Balancing Detection Rate and False Positives

  4. Reducing Computational Complexity
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In signature-based intrusion detection, the goal of optimization is to find a set of signatures that maximizes the detection rate while minimizing false positives. This balance is crucial to ensure that the intrusion detection system is both effective and efficient.

Multiple choice

In intrusion detection, what is the trade-off between detection rate and false positive rate?

  1. Higher detection rate leads to lower false positive rate

  2. Higher detection rate leads to higher false positive rate

  3. Lower detection rate leads to lower false positive rate

  4. Lower detection rate leads to higher false positive rate
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In intrusion detection, there is a trade-off between detection rate and false positive rate. As the detection rate increases, the false positive rate also tends to increase. This is because the system becomes more sensitive to detecting intrusions, which can lead to more legitimate activities being误报 as intrusions.

Multiple choice

What is the purpose of using optimization in security analytics to detect zero-day attacks?

  1. Optimizing Data Collection

  2. Optimizing Data Analysis

  3. Optimizing Data Dissemination

  4. Optimizing Data Storage
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In security analytics, optimization techniques are used to optimize the analysis of large volumes of security data to detect zero-day attacks. The goal is to identify patterns and anomalies that indicate the presence of zero-day attacks, which are previously unknown and highly sophisticated attacks that can evade traditional security defenses.

Multiple choice

How can data privacy and security be protected in sports technology?

  1. Encryption

  2. Access control

  3. Data retention policies

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All of the above can be used to protect data privacy and security in sports technology.

Multiple choice

Which of the following is NOT a common cybersecurity metric?
