LAW, ETHICS, AND SECURITY
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.
· The design of the database should be organized in a manner that the database system provides the overall service which is best for the organization. By this it can give response for the high critical applications when compared to less critical applications.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
4. What is Security And Authentication
Security definition: Data security refers to
protective digital privacy measures that are
applied to prevent unauthorized access to
computers, databases and websites.
Authentication Definition: Authentication is
the process of recognizing a user's identity. It is
the mechanism of associating an incoming
request with a set of identifying credentials
5. 4 Keys of Authentication
Data security is also known as information
security (IS) or computer security.
Introduction to User Authentication: A
basic security requirement is that you must
know your users. You must identify them
before you can determine their privileges
and access rights, and so that you can audit
their actions upon the data.
6. Passwords for Authentication
Passwords are one
of the basic forms of
authentication.
A user must provide
the correct
password when
establishing a
connection to
prevent
unauthorized use of
the database.
7. Strong Authentication
Strong authentication has important
advantages:
More choices of authentication mechanism
are available, such as smart cards,
Kerberos, or the operating system.
Many network authentication services, such
as Kerberos and DCE, support single sign-
on.
8. Proxy Authentication and Authorization
It enables the database administrator to regulate
which users are allowed to access the database
server through a given application.
It enables the administrator to audit actions of the
application acting on behalf of a given user.
11. The security of the location
where the database is stored
Even if you know that the
contents of a database file
are safe, if the file is stored
in a location that is not fully
secure.
Someone might introduce
unsafe content into the
database.
You should be careful when
deciding to trust database
files that are stored in
locations that might not be
secure.
13. Level of data security
Human level
Corrupt/careless user
Network/user interface
Database application program
Database system

Physical level
14. 14
Physical/OS Security
• Physical level
– Traditional lock-and-key security
– Protection from floods, fire, etc.
• E.g. WTC (9/11), fires in IITM, WWW conf website, etc.
– Protection from administrator error
• E.g. delete critical files
– Solution
• Remote backup for disaster recovery
• Plus archival backup (e.g. DVDs/tapes)
• Operating system level
– Protection from virus/worm attacks critic
15. Database and Application Security, Nov 2006

Security at the Database
• Authentication and
authorization
mechanisms to allow
specific users access
only to required data
• Authentication: who
are you? Prove it!
• Authorization: what
you are allowed to do
16. SECURITY Policies
Database security officer secures the
system and data
Work with the database administrator.
Security policy
Collection of standards, policies, procedures to guarantee security.
Ensures auditing and compliance
Security audit process identifies security vulnerabilities.
17. Security Pearls
Back up key files
Use encryption on sensitive data
Use good passwords
Network security requires expertise
authentication
encryption
firewalls
18. 18
User Authentication
• Password
– Most users abuse passwords. For e.g.
• Easy to guess password
• Share passwords with others
• Smartcards
– Need smartcard
– + a PIN or password
