Cyber Security - Policy-Based Information Management Systems Or IMS Solutions.



Several publications that chronicle the history and development of the PBM paradigm can be found in the present literature. 

The early publications devoted to this paradigm emphasized the importance of security concerns. 

In this sense, the first policies in charge of determining the rules by which access control systems were governed were security policies. 

Access control methods determine whether a resource's access should be permitted or prohibited based on the system administrator's security rules. 

Different access security levels may be assigned to security policies, each with its own set of criteria for determining what should and should not be permitted. 

To safeguard diverse things on shared computers, the access control matrix was created. 

Objects shared across domains, such as files, memory, and terminals, were secured by various access privileges. 

Each matrix element had a collection of access characteristics that defined the domain's access rights to the objects. 

Read, write, owner, call, and control are all examples of attributes. 

Another method provided as an alternate way to the access control matrix was Access Control Lists (ACLs), which presented the matrix information in a column format. 

Confidentiality and integrity are two crucial components of the security problem that IMSs take into account. 

The first formal model to prohibit unauthorized exposure of information was the confidentiality policy model. 

This concept was designed to formalize the Department of Defense's security. 

It was based on the state machine idea, in which a specified set of access control rules were organized by states and transition functions were used to connect them. 

The levels of security varied from the most sensitive (Top Secret) to the least sensitive (Top Secret) (Public). 

Users could only access and produce material if their security level was equal to or higher than their own. 

Finally, despite the fact that role-based access control (RBAC) is not directly related to policy definition, it has been acknowledged as a security paradigm for defining and enforcing organizational access control rules. 

RBAC is a security method that separates user assignment to roles and enables for authorization management. 

Information integrity, on the other hand, is the assurance that data has not been tampered with or corrupted by malevolent users or system failures. 

Integrity rules, in this sense, explain how the system's information's validity should be maintained. 

The first integrity policy model outlined the factors that must be taken into account when designing safe computer systems. 

Another important feature of the security area is privacy. 

Individuals and organizations have the opportunity to regulate the conditions under which their personal information is collected and used. 

Many works based on privacy rules and aimed to safeguard sensitive information have been developed in recent years. 

Business practice and legal issues drive privacy policies, which are long-term pledges given by an organization to its end users. 

In this regard, in, a system was presented that makes privacy policy writing, implementation, and compliance monitoring easier. 

A framework was presented that could describe and enforce privacy standards by providing a formal definition of purpose and offering a modal-logic language for explicitly expressing purpose limitations. 

Enterprise Privacy Practices (E-PP) is a platform that specifies technologies for privacy-enabled consumer data management and communication. 

This approach distinguishes between an enterprise-specific deployment policy and a privacy policy that spans the whole data life cycle. 

In terms of evaluating the effectiveness of privacy policies, several tests were conducted to see if apps with privacy policies were more likely to protect personal information than apps without privacy policies, as well as an empirical study of online privacy policies and tools for users with privacy concerns. 

The link between privacy policies and user responses was researched in the e-commerce arena, revealing that privacy risks transmit the impacts of a privacy policy's contents on user behavior. 

Various security theories and techniques that have been used to assure computer security in recent years are investigated. 

The authors of this research also go through a number of security principles and the models that are used to guarantee that these security standards are followed. 

Various higher-level and complicated models are built on the foundation of security models (such as access control models and protection rings). 

An authentication and confidentiality technique based on homomorphic encryption and directed to Mobile Cloud Computing (MCC) was described. 

This work also includes a recovery method for mobile users to get secure access to faraway multi-cloud servers. 

The authors have supplied a prototype of the suggested framework to show its robustness, efficiency, and security. 

Privacy and security are also important considerations in the Internet of Things (IoT) paradigm. 

The security problems of IoT and MCC technologies are researched and assessed in this regard in. 

According to the authors of this paper, cloud computing technology enhances the IoT's functionality. 

In recent years, the networking paradigm has attracted interest from both corporate and academic research communities as one of the many current study subjects where policies may be implemented to simplify managerial responsibilities. 

Several proposals aimed at policy-based network management (PBNM) with various goals can be found in the literature. 

In, a methodology for refining rules in PBM systems was presented for network security and privacy. 

To turn high-level aims into low-level policies, the refining process followed a set of phases. 

A policy-based access control system was proposed in another proposal, which prevented detrimental interference caused by faulty equipment or malevolent users. 

A set of policy-based components was created for this solution, which was combined with the algorithms used by software-defined radios to identify interference produced by malfunctioning devices. 

The suggested policy-based components assured that a radio did not deviate from policy standards. 

This research also provided safe policy administration and dissemination systems to prevent malevolent users from adding or changing policies that already exist. 

FRESCO was an OpenFlow security application development framework that made it easier to create detection and mitigation modules quickly and modularly. 

The compatibility of the Destination Addressing Control System (DACS) scheme for the cloud environment with virtualization technology was investigated in terms of network communications privacy. 

They specifically advocated including the DACS into the PBNM in order to control network resources through policies. 

Ethane was another system that used the Flow-based Security Language to enable network administrators to specify access control rules (FSL). 

With the introduction of SDN in recent years, network management has become more dynamic. 

OpenSec was, in this sense, an OpenFlow-based framework that enabled network administrators to develop and enforce security rules. 

These regulations established which security services must be used and the security levels that govern how OpenSec responds to hostile traffic. 

The efforts of business and academia in recent years have also been concentrated on energy-efficient network techniques. 

A deep survey with a deep comparison of a number of energy-efficient network approaches can be found in the current literature in this regard. 

The power consumption of mobile communication systems was quantified in the solution published in. 

It was discovered that enhancing the energy efficiency of base stations (BSs) with low traffic loads has a large potential for lowering energy usage. 

In, another idea was presented to improve the efficiency of power amplifiers for wireless BSs. 

In, the variance in traffic patterns over time was analyzed in order to determine whether BSs should sleep or not. 

Another option was to use a control system that allowed tiny cells to turn off all components when they weren't servicing active connections. 

A transfer actor-critic algorithm (TACT) was devised to speed up the decision process of turning on/off the BSs by using past data from surrounding areas. 

The usage of software routers for mimicking network equipment capabilities was suggested, as well as the advantages of the emulation environment. 

Finally, in, another approach aimed at improving energy efficiency was proposed. 

It was specifically characterized as a policy-based framework for resource management in fog computing. 

This solution took the fog computing idea a step further by allowing for safe cooperation and interoperability across various user-requested services. 

To demonstrate the importance of policy management as a basic security management module in a fog environment, many scenarios were given. 

Another major subject in networks is Quality of Service (QoS), for which numerous policy-based solutions have been developed. 

Procera was an event-driven network control framework that managed and configured the network state using high-level rules. 

This technique allowed the controller to manage the network state using dynamic policies that were converted into a set of forwarding rules. 

A novel goal function for IPv Routing Protocol for Low Power and Lossy Networks (RPL) based on Fuzzy Logic was proposed to address the constraints of the established objective functions, allowing the optimal pathways to the destination to be selected. 

In, a suggestion was presented for a new transfer learning approach for spectrum management in cognitive radio networks to enhance QoS. 

Transfer learning offers much greater QoS and throughput than dispersed reinforcement learning, according to this approach. 

When several policies coexist, conflict resolution is a critical part of operating a policy-based system. 

When implementing rules to offer QoS, the issue of conflict resolution is handled. 

PolicyCop, a QoS policy management system based on SDN and aimed at OpenFlow, followed the SDN methodology. 

PolicyCop enabled the definition of QoS service level agreements (SLAs) and policy enforcement control. 

This approach also kept track of the network's state and used rules to change the network's settings.
