Reviewer 2 Report

Comments and Suggestions for Authors

The proposed work has a contemporary theme. The work is of a practical nature and applicability. The authors propose a way to secure against DoS attacks on GPS devices, by integrating their developed IPS/IDS algorithm embedded in the firmware of a specific GPS device. The work is written comprehensibly without using complex expressions.
Work strengths:
1. The authors have developed their own IPS/IDS algorithm. The same is described in detail in the work;
2. Multiple simulations were carried out to prove the applicability of the developed algorithm;
Recommendations and remarks:
1. To add a new section with number 2 under the name "State of the problem" or another, more appropriate title according to the authors. The present subsections 1.1 and 1.2 shall be included in this section;
2. Subsection 1.1 to be renamed subsection 2.1 with another title, such as “DoS and DDoS attacks into IoT tracking devices” or another, more appropriate title according to the authors. In this subsection, describe in detail the principle of DoS and DDoS attacks directed against GPS devices: principle of execution of the attack (how it is carried out through the GPS network or through the mobile data network); whether or not they differ from standard DoS and DDoS attacks, in IP networks (Internet); what happens to the GPS devices when they are subjected to these attacks and more;
3. Subsection 1.1 to be renamed subsection 2.2 with the same title;
4. To add subsection 2.3 with the title "proposed IDS/IPS mechanism", including lines 147 - 164 in this section;
5. The present section 2 to be divided into two subsections. In the first subsection, describe the test device used, and in the second subsection, include the developed algorithm;
6. In the "Discussion" section, describe in more detail the advantages and disadvantages of the proposed algorithm; where it can additionally be applied and for what; are there any restrictions in its application, etc.
