Context: Security issues have increased recently because of the increased use of networking. The researchers have proposed many models, approaches, and models, for example, attack graphs. The attack graph model is a valuable tool for vulnerability analysis as well as for displaying all network paths. In general, attack graphs can be utilized for a variety of purposes, including the calculation of security metrics. Nonetheless, in order to sufficiently safeguard networks, a technique for gauging the security degree provided by these activities is required, as “you cannot improve what you cannot measure.” The security level of a system or network is typically represented by network security metrics in qualitative and quantitative ways. The network security metrics are typically employed to evaluate a system's security level and meet security objectives. Aim: This study aims to present a review of attack graph-based security metrics and analyse the previous work. Provides the limitations and issues the researchers faced to improve this important research area. Methodology: The attack graph security metrics field was thoroughly investigated in all research, and four databases—ScienceDirect, Web of Science (WoS), Scopus, and IEEE—were used to collect data between 2001 and 2022. Results: 46 papers were founded on attack graph security metrics with different methods and techniques based on the exclusion and inclusion criteria. The results of the taxonomy created three significant categories: proposed, implemented, reviewed, and surveyed. We believe this study will aid in highlighting research ability, which will subsequently broaden and establish new research topics.

Background: Pericallosal tuberculoma, a rare form of intracranial tuberculoma, affects the corpus callosum and results from tuberculosis (TB), a bacterial infection that can cause a myriad of symptoms. Diagnosing this condition can be challenging but can be confirmed through imaging studies and biopsy. Treatment involves a combination of antitubercular medications and surgical removal of the lesion if it is in a critical location or causing significant symptoms. This article describes the surgical management and imaging characteristics approach to a patient with intracranial tuberculoma., Case Description: A 17-year-old female with a history of TB meningitis nine years ago presented with one week of recurrent seizures and mild third nerve palsy, later diagnosed as a tuberculoma of the corpus callosum through radiological imaging and biopsies. A total surgical resection of the lesion was performed using a contralateral interhemispheric frontal parasagittal approach. The patient went under observation and suitable follow-up plans., Conclusion: Surgical management can effectively treat cerebral granulomas and improve neurological deficits in patients with recurring TB. Despite the possibility of complications, the benefits of such measures are highlighted in this case, suggesting that surgical intervention can be a viable option for achieving optimal outcomes in these patients., Competing Interests: There are no conflicts of interest., (Copyright: © 2023 Surgical Neurology International.)

Background: Mentorship programs are crucial for continuous medical education, improving personal confidence, knowledge, and skills, and have been associated with staff retention and overall career satisfaction. However, there are limited studies evaluating the effectiveness of mentorship programs in neurosurgery. The study aims to evaluate the effectiveness of mentorship programs in neurosurgery, focusing on knowledge and skill development, personal growth, and networking opportunities., Methods: A cross-sectional study was conducted during the 9th Hoz Neurosurgery Mentorship Program, involving 175 participants from 16 countries. Precourse and postcourse surveys assessed participants' neurosurgical knowledge, research experience, personal abilities, and acknowledgment of neurosurgical subspecialties., Results: Of the participants, 89% were from Iraq, with the remaining from various countries. Most participants were medical students in their early years. The average neurosurgical knowledge score increased from 35.29/60 precourse to 38.4/60 postcourse. The total passing percentage increased from 71% precourse to 86% postcourse. Prior to the program, 87% of participants had not participated in research projects, and 69% had not presented at scientific meetings. Feedback from the postcourse survey highlighted personal development, leadership, teamwork, public speaking skills, and ethical and moral aspects of being a neurosurgeon., Conclusions: Mentorship programs are effective in advancing the skills and capabilities of medical students, junior residents, and physicians. Evaluation of their effectiveness should consider not only scientific knowledge but also practical capabilities, personal growth, and critical thinking development. Free-of-charge programs with diverse participants and overall effectiveness make such experiences unique compared to other mentorship opportunities., (Copyright © 2023 Elsevier Inc.
