Database security is a set of practices and technologies used to secure database management systems against malicious cyber-attacks and unauthorized access. Ensuring a database is intricate because it requires knowledge of multiple areas of information security, including application security, data security, and endpoint security.
Moreover, Database Security is the safeguarding of sensitive data and the prevention of data loss. Database Administrator (DBA) is responsible for ensuring database security.
Database security involves protecting data from unauthorized access, alteration, or deletion. It ensures only authorized users can view, change, or delete data according to their access privileges. Key aspects of database security include access controls, encryption, auditing, and monitoring for compliance with security standards to protect the confidentiality, integrity, and availability of the data.
This document discusses techniques for securing databases. It describes database security as protecting databases from threats to their confidentiality, integrity and availability. It identifies various threats such as unauthorized access, malware infections, and physical damage.

Legal and ethical Standards
Availability – the system should allow data to be available to the authorized person at the right time and with less effort needed to access it.
Integrity – data in the database should modified by only the authorized persons and in the correct way. Such that such modification or alterations do not bring conflict in the database meaning data should not be tampered with. If tampered this could amount to misuse.
Confidentiality factor- a system should be designed in such a way that it does not allow unauthorized person to access information which they don’t have permission for Vinyl records . There should be restriction to data accessed by different parties.
The system being developed should not negatively affect the health, safety and welfare of the users instead it should make life better.
A system developed should not perform illegal actions such as corrupting data, leaking of information or used in spying.
The policies and procedures used in the operation to the system being developed should must assure reliable data.
A system developed should be licensed; the legal process of obtaining license should be used.
One should not use software product that they don’t have license or are not authorized to use by the owner. Intellectual rights should not be violated.
Legal compliance
To ensure accurate data is entered every time the system should be able to validate data before Restricting access to data in the database through separating data into different tables with where user privileges are restricted. The design of the database should enable separating different object attributes of entities to restrict access to the whole entity information hence able to protect data from unauthorized access.
Database design methodology used in this case must allow scalability of the information such that the database will continue to function properly even when the data is increasing and hence ensure availability and reliability.
Integrity of the data should be done by setting access privileges in the physical design of the database which is implemented.
Security should be incorporated in all phases of the database development cycle. In the design phase the system.
Standards
The access to different types of databases is done through DBMS only, so for this the standards are easier to enforce. Standards may include and relate to structure of data, format of data, naming of data etc.... generally standardized data is used for the purpose of data exchange between various systems.

This document discusses enforcing multi-user security policies in cloud computing. It describes using key-policy attribute-based encryption (KP-ABE) to allow flexible and fine-grained access control of encrypted data stored on cloud servers. The database is encrypted using KP-ABE before being stored. A key management authority generates key sets for authorized users to decrypt portions of the database according to assigned access policies. This allows complex queries to be run on the encrypted database while protecting data confidentiality even from the cloud server.

A robust and verifiable threshold multi authority access control system in pu...IJARIIT
Attribute-based Encryption is observed as a promising cryptographic leading tool to assurance data owners’ direct
regulator over their data in public cloud storage. The former ABE schemes include only one authority to maintain the whole
attribute set, which can carry a single-point bottleneck on both security and performance. Then, certain multi-authority
schemes are planned, in which numerous authorities distinctly maintain split attribute subsets. However, the single-point
bottleneck problem remains unsolved. In this survey paper, from another perspective, we conduct a threshold multi-authority
CP-ABE access control scheme for public cloud storage, named TMACS, in which multiple authorities jointly manage a
uniform attribute set. In TMACS, taking advantage of (t, n) threshold secret allocation, the master key can be shared among
multiple authorities, and a lawful user can generate his/her secret key by interacting with any t authorities. Security and
performance analysis results show that TMACS is not only verifiable secure when less than t authorities are compromised, but
also robust when no less than t authorities are alive in the system. Also, by efficiently combining the traditional multi-authority
scheme with TMACS, we construct a hybrid one, which satisfies the scenario of attributes coming from different authorities as
well as achieving security and system-level robustness.

Network security policies are important to protect organizational assets from threats. The document discusses:
1) Identifying key assets that need protection, such as critical databases, applications, customer/employee information, and servers.
2) The purpose of security policies is to inform users of obligations, specify security mechanisms, and provide a baseline for protection.
3) Network security involves securing access across different segments, applying device security, and implementing policies for internet access, remote connections, firewalls, and acceptable use. Layered security makes it harder for attackers to compromise critical systems.
Database security is a growing concern as the amount of sensitive data collected and retained in databases
is fast growing and most of these data are being made accessible via the internet. Majority of the companies, organizations and teaching and learning institutions store sensitive data in databases .As most of these data are electronically accessed , It can therefore be assumed that , the integrity of these numerous and sensitive data is prone to different kind of threat such as{Unauthorized access, theft as well access denial}. Therefore, the need for securing databases has also increased The primary objectives of database security are to prevent unauthorized access to data, prevent unauthorized tampering or modification of
data, and to also ensure that, these data remains available whenever needed. In this paper, we developed
a database security framework by combining different security mechanism on a sensitive students information database application designed for Shehu Shagari College of Education Sokoto (SSCOE) with the aim of minimizing and preventing the data from Confidentiality, Integrity and Availability threats
This document presents a database security framework developed by the authors to secure a student information database. The framework combines various security mechanisms to enforce confidentiality, integrity, and availability (CIA) of the data. The framework was tested on exam officers who were either granted or denied access based on correct or incorrect login details, demonstrating the effectiveness of the security measures. The framework models the database system using use case and class diagrams and divides it into three layers - the presentation layer, application logic layer, and data/domain layer. The results indicate the framework successfully authenticates authorized users and restricts unauthorized access in line with the CIA principles.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Locking Down Your Data: Best Practices for Database Security
1. Database security is a set of practices and technologies used to secure
database management systems against malicious cyber-attacks and
unauthorized access. Ensuring a database is intricate because it requires
knowledge of multiple areas of information security, including application
security, data security, and endpoint security.
Moreover, Database Security is the safeguarding of sensitive data and the
prevention of data loss. Database Administrator (DBA) is responsible for
ensuring database security.
The purpose of database security is to safeguard not just the information
stored in the database but also the data management system and any
applications that connect to it against unauthorized usage, corruption, or
intrusion. A database’s physical or virtual server and the surrounding computing
and network environment must be guarded and hardened for maximum security.
Another aspect of database security involves safeguarding and strengthening
the physical or virtual server that hosts the database and the associated
computing and network infrastructure.

3. Conclusion: Best Practices for Database Security
3. Database security refers to the measures taken by businesses to safeguard
their databases, DBMSs, and associated systems from intrusion and data loss.
The data is harder to access and use thanks to the security controls, which
include architectural methods, application design, procedural protocols,
processes, and tools.
Inadequate implementation of database security measures can adversely affect
operational efficiency, application performance, and user experience. Security
must weigh functional requirements to reduce risk to an acceptable level while
preserving usability. Furthermore, Database security in DBMS is a method for
protecting and securing a database from malicious or unintentional attacks.
Best practices and procedures for database security design exclusively for
databases. Organizations must protect their databases and the entire
environment in which they operate. Implementing more general security best
practices applicable to linked systems is also necessary for adequate database
security.
Database Security Best Practices
Keep databases in a secure area with limited access to prevent hacking. The
following are the eight best practices for Database Security.
Separate Database Servers
Regarding attacks, web servers are prime targets since they must be publicly
available to use. A successful attack may grant the attacker access to the
website or application’s host server, allowing them to access any other content
hosted on the server.
4. Place databases on a distinct container, physical server, whether that be a
physical or virtual server, to provide for further hardening and to prevent access
in the event of a website or application compromise. For the separate server,
merely activate the necessary ports. If feasible, change the default
communication ports to make attacks more difficult to execute.
Certain experts suggest implementing an HTTPS proxy server as an
intermediary between the database and the queries. However, functionally
segregating the web and database servers can yield an equivalent outcome. But
a proxy server may be helpful for internal network databases that can be
accessed directly by authorized network users or devices. For enhanced
database security, allocating the database server to a separate physical or
virtual network segment and enforcing strict access privileges is advisable.
Ensure The Physical Database Security
When selecting the best hosting provider, consider finding a web hosting firm
with a track record of treating security issues with the seriousness they
deserve. If you want your website to be safe, you should avoid using free
hosting services whenever possible.
Having video cameras, locks, and security personnel in place will help keep your
servers safe from outside threats. All physical server access should be logged
and granted only to the appropriate personnel to minimize the danger of harmful
activity.
If you intend to use web servers, investigate the hosting company. Ensure that
there are no red flags regarding previous data intrusions or loss. For enhanced
5. database security, allocating the database server to a separate physical or
virtual network segment and enforcing strict access privileges is advisable.
Secure Database User Access
Few people should use the database as feasible and as few programs and APIs
as possible. To ensure secure access, grant access only after receiving network
or application permission, and by the principle of least privilege. Additionally,
grant access for the shortest feasible duration. User authorization, privileged
access, and the usage of databases in development and operations (DevOps)
are the three main branches of this best practice.

User Authorisation
6. The admin, or system administrator, controls who can access the database and
how. The administrator assigns users the appropriate database roles and grants
them rights. Row-level security (RLS) limits who can read and write to rows of
data based on the user, their roles, and the query which runs.
Centralized identity and permission management, password storage reduction,
and password rotation policies are possible with database security systems.
Permissions should be managed by roles or groups rather than individual users
in smaller organizations. Moreover, access control in DBMS prevents data
breaches by restricting access to sensitive information to user groups and
denying access to others.
Privileged Access
Admins should only have the privileges they need to do their jobs. Privileges
should be provided and removed periodically. Larger companies use privileged
access management (PAM) software to automate access management.
Authorized users receive a temporary password, PAM logs activity, and inhibits
password sharing.
DevOps Database Use
DevOps teams use test environments to ensure that applications can connect
to and properly utilize databases, even though they are not technically users.
Using production databases might cause unintended disclosures of sensitive
information.
Use Database Firewalls
Access to databases makes them useful, but that access must be protected.
Database-specific firewalls, which by default prevent access, form the first line
7. of defense. The firewall should only allow traffic from authorized clients, such
as programs, web servers, and end users. It should also prevent the database
from making outgoing connections unless necessary.
Users should be restricted from having direct database access. Use established
change management processes and security monitoring alarms to manage
modifications to firewall rules. A more robust database server operating system
firewall may be sufficient for organizations with fewer resources.
Maintain Frequent Application Updates
In nine out of ten applications, obsolete software components exist.
Furthermore, research into WordPress plugins found that 17,383 had yet to be
updated in two years, 13,655 in three years, and 3,990 in seven years. Using out-
of-date software to manage databases or host a website is a significant
security risk.
It’s important always to use database security management software from
reputable providers. The software must also be consistently updated and
patched promptly. Furthermore, it is advisable only to utilize widgets, plugins,
and third-party applications with regular updates.
Harden The Database
It’s crucial for protecting the database, like the server, to prevent vulnerabilities
and security breaches. Database hardening differs depending on the platform,
but everyday actions include improving password protection and access
controls. Safeguarding network traffic and encrypting sensitive database fields
are also important measures.
8. Moreover, to prevent the exploitation of the database in ways that aren’t
immediately obvious, disable or uninstall any services or features that are not
currently in use. The database should enable all security controls. Enable some
features by default. Others may be turned off for specific reasons. For each
feature, examine it and document the reason for disabling it. For sensitive data,
admins should activate row-level security and dynamic data masking.

Maintain Database Backups
It is recommended to back up both your website and database regularly. This
means that private information is safe from accidental deletion or hacking.
Here’s how to make a database backup in Windows or Linux. As an extra
precaution, encrypt the backup file before storing it on a separate server. A
secondary database server keeps your information safe if your primary server
becomes inaccessible or at risk.
9. Assign all Users Security Roles
Finally, we will discuss the majority’s strategy to ensure user database security.
Role-based security is a relatively straightforward but highly effective method
for restricting data access. Organizations that provide API access to their
databases will benefit from this best practice.
In addition, security authentication is necessary for accessing a database using
an API. Attempting to access the database without authentication severely
restricts access and modifications. This method ensures that the database
remains secure.
Conclusion: Best Practices for Database Security
Data breaches can result in penalties, adverse business effects, and legal
action. Unfortunately, accidents and security incidents can occur even in well-
prepared businesses. The cost will depend on how much risk the company is
10. willing to take. Moreover, a solid database security practice will mitigate the
growing threat of data breaches, even as attacks’ frequency, severity, and
financial repercussions increase. Organizations should review, employ, and
maintain as many best practices as possible in order to reduce their breach risk
and future incident costs.
