- Keywords:classified information; crisis situations; technology
- Summary/Abstract:The management of classified information is a critical aspect of organizational operations, especially in sectors such as government, defense, and private enterprises dealing with sensitive data. Effective information activity encompasses a range of processes and protocols designed to safeguard classified information from unauthorized access, disclosure, modification, or destruction. The policy of the Republic of Bulgaria on the protection of classified information is implemented in accordance with the directives on interoperability with NATO and the EU, which requires the creation of new laws and regulations related to the security of sensitive information. The term "classified information" was first introduced by the Classified Information Protection Act (CIPA). By its very nature, this is information constituting state secrets, official secrets and foreign classified information. The need to protect classified information arises from its importance for the national security of the Republic of Bulgaria. It protects facts and circumstances, free access to which could harm the interests of the State as a whole. Restricting access to classified information aims to minimise risks, prevent threats or damage to the interests of the Republic of Bulgaria relating to sovereignty, independence, territorial integrity, defence, constitutional order, foreign policy and international relations.

- Summary/Abstract:Intrusion Detection and Prevention Systems (IDPS) are critical components of modern cybersecurity infrastructure. These systems help organizations protect their networks and data by detecting and preventing unauthorized access, misuse, and attacks. However, choosing the right type of IDPS can be a challenging task due to the complexity of modern cyber threats and the diversity of IDPS solutions available in the market. This paper discusses some of the challenges in choosing the type of IDPS to increase the level of cybersecurity in an organization. For this purpose, a comparative analysis of the correspondence between IDPS types and their ability to protect against ransomware has been developed, using the classification of tactics and techniques by the MITRE ATT&CK framework.

Upon designing their accounting policy, pension insurance companies must consider the impact of the economic, political and social environment and the factors that affect their specific pension insurance business in order to be able to present truly and fairly, completely and accurately, authentically and comparatively the information for their financial position, financial performance, movement of their cash flows, changes in equity and in the specific (technical) provisions they have established. The accounting policy is a model of organising the accounting reports of the respective company and of subsequent disclosure of the outcomes of this activity in the company’s financial statements during different reporting periods, in accordance with the changes that have occurred in the external economic environment. In the course of designing and practical implementation of their accounting policy, pension insurance companies must observe specific accounting conceptual frameworks, statutory principles, common rules and approaches to organise their accounting reports. Any legally established accounting policy is always able to adequately respond to the changes in the society in the context of crisis – economic, political, social, or healthcare.

The practical analysis of said parameters and values can be made promptly and efficiently by using the respective software. It is necessary that real estate companies have such software to allow teams to con-duct the financial management of such companies relatively quickly while establishing precisely the different values of the basic value parameters and value levels, respectively, namely ‘financial result from sales’ and ‘financial result of the company’, as well as gaining a general approximation for the other two value levels - company liquidity and solvency. The report is based on the applicable accounting legislation in Bulgaria while also taking into account certain theoretical premises. Therefore, it has considerable practical implications.
