Information stored in databases is regarded as a valuable asset from a cooperate perspective (Malik & Patel, 2016). Therefore, the security of this information remains paramount and a vital requirement when dealing with database management. Databases comprise data and information with varying degrees of significance. Some data might be more important than the other.

This calls for the adoption of strategies through which such information can be safeguarded, and the number of people who can access the information can be limited. Since database security is an issue affected by other internal and external factors, it cannot be isolated (Mousa, Karabatak & Mustafa, 2020). To handle it, many other things need to be addressed. "As the organizations increase their adoption of database systems as the key data management technology for day-to-day operations and decision making, the security of data becomes crucial.†In this light, this paper will examine strategic and technical database security measures. The paper will further discuss the Clark and Wilson model of developing databases for organizational security.

Strategic and Technical Database Security Measures Database security requires vast experience to uphold the security of the sensitive data and information stored. Current knowledge about cybersecurity is also essential as new threats emerge every day. The following are some of the golden strategic and technical database security measures. The first one is the separation of web servers from standard servers. Database servers need to be kept and handled separately from the web servers (Malik & Patel, 2016).

Keeping them apart increases cybersecurity of the database and the website in a manner that even if hackers manage to access web server admin, they are not capable of accessing database servers. An application that is not a must for the servers to operate should be kept out of the servers. They can also be used as loopholes through which the hackers can find their way into the information protected. Secondly, all files, together with their backups, should be encrypted. Regardless of how robust database defenses are, hackers’ chances infiltrate typically into the system.

It is worth understanding that cybercriminals are not the only threats to data security. Some employees might be thinking other ways about the information available (Kothari, Suwalka & Kumar, 2016). Encrypting data and storing it in an unreadable form towards employees and hackers creates the final and most secure line of defense against any intruders finding their way into the system. The third measure is regularly updating patches. Database commonly uses plugins and widgets in their operations.

These are the significant roadmaps that the cybercriminals use in bypassing existing database security. This route tends to be simpler for hackers when the patches are not updated. Even though the internal defenses are strong, failure to update the database patches makes them vulnerable (Kothari, Suwalka & Kumar, 2016). Running updates regularly enhances the security in them and hence, keeping intruders far away. The fourth measure is a regular audit of the database to check the degree of security in place.

When databases hold highly sensitive information like consumer credit, hackers make such databases their primary targets (Mousa, Karabatak & Mustafa, 2020). Once it is felt that all security measures have been implemented, testing the security should begin (Kothari, Suwalka & Kumar, 2016). This can be done by self-hacking or auditing the database to identify potential loopholes through which hackers can find their way into the system. Successful hacking of the system implies that database security is not strong enough. The last measure is ensuring the security control of database servers are at their maximum.

There is a need to ensure that the latest version of the database is in use. Having the lasts version helps minimize the existing software vulnerabilities. Security measures and control protocols always remain at par (Mousa, Karabatak & Mustafa, 2020). This also needs to be associated with a regular update of passwords and changing the default passwords. This will ensure that unauthorized or old users do not win access to databases.

Database Security Model Clark and Wilson model This is among the best security models who uphold integrity. Figure 1:The Clark-Wilson Model Figure 2:Clark and Wilson model scientific diagram This model was summarized and contrasted to MAC in 1987 by Clark and Wilson. The approach of the model was developed for the pencil and paper world. The model was aimed at addressing several security constraints using an informative transaction and the principle of separation of duties (Pernul, 1994). When these principles are transferred to the database security management, they are interpreted as follows.

Security subjects: These are assigned according to the roles people have. Users are classified according to their roles in the organization. User roles define the functions they are entitled to. Each role of the user is mapped into the database at an ideal time, and the user is allowed only to play one role at a time. Wilson and Clark permit authorized users to access data alone (Pernul, 1994).

Well-formed transaction: This is a type of transaction that operates on an assigned group of data on the condition that all relevant security measures and integrity hold and that are satisfied. Pernul (1994) points out that "they should provide logging and atomicity and serializability of resulting sub-transactions.†Throughout the model, data elements referenced by the transactions usually are generally not specified. Hence, the model rejects ad-oc database queries. Separation of duties: The principle of separation of duties demands that every set of users be assigned a unique set of responsibilities according to the role the users are assigned in the organization. This leaves out only one way through data that could be accessed.

This is through the user role in the organization. In case a given user needs more information, another user in a different role comes in, forming a transactional domain temporarily to win information (Pernul, 1994). Conclusion In conclusion, the value with which data stored in the database hold is directly proportional to the level of security adopted. In the contemporary world, databases have been regarded as valuable assets of the cooperating organizations. This is regardless of the type of enterprise in place.

Measures through which database security can be upheld include the separation of web servers, all files together with their backups should be encrypted, regularly updating patches, regular audit of the database to check the degree of the security in place and ensuring the security control of database servers are at their maximum. Clark and Wilson's model serves to ensure the integrity of the databases. References Kothari, H., Suwalka, A. K., & Kumar, D. (2019).

Introduction

In the contemporary digital landscape, data serves as a vital asset for organizations. The integrity and security of this data, particularly when stored in databases, have emerged as critical issues faced by enterprises today (Malik & Patel, 2016). Given that databases handle a multitude of sensitive information, including customer details, financial records, and proprietary information, ensuring their security is paramount. This paper explores strategic and technical measures for database security, focusing on the implementation of the Clark and Wilson model for fostering database integrity and security.

The Necessity of Database Security

The increasing reliance on technology for operational management and decision-making amplifies the importance of data security. With the rise of cyber threats from both external actors and potential internal vulnerabilities, organizations must adopt comprehensive strategies to protect their data (Mousa, Karabatak, & Mustafa, 2020). Given the multifaceted nature of threats, effective database security cannot be perceived in isolation; it must account for both internal measures and external vulnerabilities.

Strategic and Technical Measures for Database Security

Adopting a multifaceted approach is essential for maintaining robust database security. The following five strategic and technical measures are crucial:

1. Separation of Servers

One of the most effective strategies for bolstering database security involves separating database servers from web servers. This approach mitigates the risks associated with unauthorized access (Malik & Patel, 2016). When web servers are compromised, having software and databases housed on separate servers reduces the likelihood of exposing sensitive information. This segmentation ensures that potential breaches in the web layer do not extend their reach to the database.

2. Data Encryption

Encryption of files, including backups, stands as one of the most effective measures against unauthorized data access. Regardless of the robustness of a system, the reality is that cybercriminals can exploit vulnerabilities to access sensitive information (Kothari, Suwalka, & Kumar, 2016). By encrypting data, companies ensure that even if hackers manage to gain access, the information remains incomprehensible and thus secure from unauthorized interpretation.

3. Regular Updates and Patching

Failure to regularly update database systems poses significant vulnerability opportunities for cybercriminals. Unpatched software often contains exploits that attackers can utilize (Kothari, Suwalka, & Kumar, 2016). It is crucial that organizations regularly apply patches, updates, and vulnerability fixes. By keeping all software—including plugins and widgets—up to date, organizations can significantly reduce their exposure to potential breaches.

4. Audit and Monitoring

Regular audits of database systems are vital in assessing the efficacy of existing security measures. Testing systems through penetration testing or self-assessment can reveal vulnerabilities that may not have been previously identified (Mousa, Karabatak, & Mustafa, 2020). These audits help organizations to maintain a proactive standpoint, allowing them to respond effectively to identified weaknesses before they are exploited.

5. Robust Access Control

Implementing strict access controls is essential to database security. Organizations should enforce the principle of least privilege, ensuring that users have access only to the data necessary for their role (Mousa, Karabatak, & Mustafa, 2020). Regularly updating passwords and employing multi-factor authentication can further elevate security by limiting unauthorized access to sensitive data.

Database Security Models: The Clark and Wilson Model

The Clark and Wilson model represents a significant approach to database security that prioritizes data integrity through a structured framework. The model focuses on three core principles: well-formed transactions, separation of duties, and constrained interfaces.

Security Subjects

In the context of the Clark and Wilson model, 'security subjects' refer to users and their respective roles within an organization. Each user is assigned specific permissions based on their role, therefore maintaining a clear boundary on what data they can access (Pernul, 1994). Such delineation allows for the minimization of risk associated with internal data management.

Well-formed Transactions

The concept of 'well-formed transactions' refers to any transaction that is properly structured and ensures adherence to required security measures. The model prohibits ad-hoc queries, reinforcing the idea that all access to data must occur through prescribed transactional phases (Pernul, 1994). This limitation plays a pivotal role in preventing unauthorized access attempts.

Separation of Duties

The principle of separation of duties mandates that no single user should possess permissions allowing them to both initiate and approve a transaction (Pernul, 1994). This principle aims to limit the potential for fraud and erroneous actions that compromise database integrity. By requiring collaboration among multiple users in critical transactions, organizations can significantly enhance their overall security posture.

Conclusion

The significance of database security is closely tied to the value of the information held within those systems. Organizations must remain vigilant and proactive in their approach to data management, employing both strategic and technical measures to mitigate risks. Key strategies include separating servers, encrypting data, regular updates, robust audits, and strict access control.
Additionally, employing models such as the Clark and Wilson model creates a structured framework that emphasizes integrity through well-formed transactions and separation of duties. The combination of these measures can significantly enhance database security, thereby protecting valuable organizational data from both internal and external threats.
