Describes the 4 types of basic security applied on the computer system for the end user?

The security is used to work on the logical level protection applied by the application, operating system or database program or network used antivirus to protect the database saved into the storage device of the personal or official used computer system.

The database included a sensitive database for personal information or an official database related to the business model to protect from the unknown access of the user.

The security protection is necessary available on the application to protect the data of the user of their personal database or official database depends on the protection level and quality of security model such as:- a username is only used to verify without any password then this is a low level of security layer on the user account to access it on the application software. The other password layer is used to make a strong security model to verify the user account which provides more protection on the application software over the user account access on the application software on the computer system.

If the user applied more protection layers using the secret code after the verification of the username and password then secret code to make a higher level of security model to allow the permission to the user to access their user account on the application software. It is also entered by the keyboard input resource used commonly on the computer system on the application software.

The four basic types of security applied to a computer system for end users include physical security, network security, software security, and data security. Physical security involves protecting hardware components from theft, damage, or unauthorized access through measures like locks, biometric authentication, and surveillance cameras. Network security focuses on safeguarding the system from cyber threats such as hacking, malware, and unauthorized access by using firewalls, encryption, and secure Wi-Fi configurations. Software security ensures that applications and operating systems are protected from vulnerabilities through regular updates, antivirus software, and secure coding practices. Lastly, data security involves protecting sensitive information from breaches, loss, or corruption by implementing encryption, backups, and access controls. Together, these security measures help ensure a safe and secure computing environment for end users.

Physical Security involves protecting the computer hardware and peripherals from unauthorized access, theft, or damage, such as using locks, biometric authentication, or secure storage. Password Security involves setting strong, unique passwords for user accounts to prevent unauthorized access, and using password managers to securely store and generate complex passwords. Software Security involves installing and regularly updating antivirus software, firewalls, and other security applications to detect and prevent malware infections and other online threats. Network Security involves configuring the computer's network settings to prevent unauthorized access, such as using secure Wi-Fi connections, disabling file sharing, and configuring firewall settings to block suspicious traffic.

• Database security protected the sensitive database and information related to personal or official database

Let’s discuss these points listed above about the computer system and security system related to the topic of “Describes the 4 types of basic security applied on the computer system for the end user?” explanation following below here:

Network security for the client user and admin user to access it

Network security for the client user and admin user to access it to use the services available on the network model connected into many computers in the network model to the network device to access many computers and connected through the data cables or wireless medium. The wireless medium also needed a protection to access through the userID number to access and their password to verify to access network model and connection to the computer to use the networking service.

The antivirus application is used to protect the transmission of the malicious files if these files are inserted into the computer of the client user in the network model.

Network security for both client users and admin users ensures secure access to network resources while preventing unauthorized intrusions. Client users typically access the network through authentication methods like usernames, passwords, or multi-factor authentication (MFA), ensuring only authorized individuals can connect. Encryption protocols such as SSL/TLS protect data transmission, while firewalls and intrusion detection systems (IDS) help block malicious traffic. For admin users, additional security measures like role-based access control (RBAC), VPNs for remote access, and logging of activities ensure they can manage the network securely without exposing it to threats. Regular security updates, access monitoring, and strict privilege controls further enhance network security for both client and admin users.

Network security measures are implemented to protect the computer network from unauthorized access, ensuring secure data transmission and safeguarding sensitive information. For client users, network security measures include firewalls, intrusion detection systems, and encryption protocols, such as SSL/TLS, to secure online transactions and communication. Additionally, client users are typically restricted to accessing specific network resources and services, with their access rights and permissions defined by the network administrator. For admin users, network security measures involve configuring and managing network security policies, monitoring network activity, and responding to security incidents. Admin users have elevated privileges, enabling them to access and manage network resources, configure security settings, and perform software updates and maintenance tasks.

Operating system or system software security to access the user account use specific services

Operating system or system software security to access the user account use specific services such as:- open an account on the computer system and use their personal options customised by its own usability on the user account of the operating system.

The operating system provides additional security if the user uses a full version of the operating system by the company to use such as:- username/password, image click verification, security code after USername and password, multi factor authentication etc.

Operating system or system software security ensures that user accounts can access specific services securely while preventing unauthorized access and vulnerabilities. It implements authentication mechanisms like passwords, biometrics, or multi-factor authentication (MFA) to verify user identities. Role-based access control (RBAC) and user privilege management restrict access to sensitive system resources based on user roles. Security features such as firewalls, antivirus software, and encryption protect against malware and cyber threats. Regular system updates and patches help fix security vulnerabilities, while audit logs and activity monitoring track user actions for accountability. These security measures ensure that only authorized users can access specific services safely within the operating system.

Operating system or system software security refers to the protective measures implemented to safeguard the operating system and its components from unauthorized access, use, disclosure, disruption, modification, or destruction. To access user accounts and use specific services, operating systems employ various security mechanisms, such as authentication, authorization, and access control. Authentication verifies the identity of users through passwords, biometric data, or smart cards, while authorization determines the level of access and privileges granted to authenticated users. Access control mechanisms, including file system permissions, user account controls, and role-based access control, regulate what actions users can perform on the system and its resources.

Application software security is applied for the end user to use their account into it

Application software security is applied for the end user to use their account into it when the application is open and run the program file then the application execute a program before access the service and shows the security layer if the user applied on it to use and passes after the verification of the user on their user account on the application on the security model.

The application uses high level or low level of security verification of the user such as:- high level security provided the object based or biometric verification and the low level of verification uses as username with password verification of the user which the user applied on the security model for their protection of the database related to the user and connected files of the application software.

Application software security ensures that end users can safely access and use their accounts within an application by implementing authentication, encryption, and access control mechanisms. Secure login methods such as multi-factor authentication (MFA), OAuth, and biometric verification help prevent unauthorized access. Data encryption protects sensitive user information during transmission and storage, while regular security patches and updates fix vulnerabilities that could be exploited by attackers. Role-based access control (RBAC) ensures that users have appropriate permissions based on their roles, minimizing security risks. Additionally, secure coding practices, firewalls, and real-time monitoring help prevent threats such as SQL injection, cross-site scripting (XSS), and other cyberattacks, ensuring a secure and reliable user experience.

Application software security refers to the measures implemented to protect software applications from unauthorized access, use, or malicious activities. To ensure secure usage, application software security is applied to end-user accounts, requiring users to authenticate themselves through usernames, passwords, or other verification methods. Once authenticated, users are granted access to authorized features and data within the application, with their actions monitored and controlled through access controls, encryption, and auditing mechanisms. This safeguards sensitive information, prevents data breaches, and maintains the integrity of the application and its data, providing a secure and trusted environment for end users to interact with the software.

Database security protected the sensitive database and information related to personal or official database

Database security protects the sensitive database and information related to the personal or official database for the end user in the database file. The relational database file is protected through the DCL of the SQL to use the command on the table which is created in the database file of the relational database model to provide the protection from the unknown user to access but the dcl is used to control the data of the table or relation in the RDBMS to provide the protection of the user database or official database. It controls the data and allows the user who knows the right information for verification to access the table or relational database model file.

The database sensitive to protect from the higher security layer of the model to provide the object based verification system on the security model such as:- finger scan, hand scan, eye scan etc, that makes a higher level of security for the privilege to use the sensitive database after verification of these verification input data based on the object database file to verify from the saved database file on the security model.

Database security protects sensitive personal and official information by implementing strong access controls, encryption, and monitoring mechanisms. Authentication methods such as usernames, passwords, multi-factor authentication (MFA), and role-based access control (RBAC) ensure that only authorized users can access or modify the database. Encryption safeguards data both at rest and in transit, preventing unauthorized access even if the database is compromised. Firewalls, intrusion detection systems (IDS), and regular security audits help identify and prevent potential threats. Backup and disaster recovery plans ensure data integrity in case of cyberattacks or system failures. By enforcing these security measures, organizations can protect sensitive data from breaches, unauthorized modifications, and cyber threats.

Database security refers to the measures implemented to protect sensitive database information from unauthorized access, theft, or malicious activities. This involves safeguarding personal and official databases that contain confidential information, such as financial records, personal identifiable information, and business-critical data. To achieve this, database security employs various mechanisms, including access controls, encryption, authentication, and auditing, to regulate who can access, modify, or delete database content. Additionally, database security also involves regular backups, updates, and patches to prevent data breaches, SQL injection attacks, and other cyber threats, ensuring the confidentiality, integrity, and availability of sensitive database information.
