Timely Patch and security updates Efficent XDR system in place Only open the necessary ports,rest all must be blocked Block all USB ports Disable/rename administrator account Only necessary privilege must be granted as per business requirments. Registry backup must be in place And top of it User awarness training and orientation must be in place regularly.

Securing an operating system involves protecting resources like SRAM, where applications set up regions for operations to prevent interference. Using mechanisms like SRD (Set, Read, and Delete) or R/W/X permissions ensures that sensitive information remains secure by managing privileges appropriately. Good programs configure these permissions, limiting access only when necessary and returning memory to the system when unused. This approach prevents breaches by isolating workspaces and maintaining the principle of least privilege, enhancing security while ensuring performance remains unaffected since this is done at the embedded system level. Proper privilege configuration is key to efficient and safe system operation.

Para proteger meu sistema operacional sem comprometer a velocidade, eu: Atualizo Tudo: Mantenho o sistema operacional e os softwares atualizados para bloquear vulnerabilidades. Escolho Segurança Inteligente: Uso ferramentas antivírus leves e eficientes. Otimizo Inicializações: Desativo programas desnecessários para melhorar o desempenho. Aproveito Recursos Nativos: Ativo as funcionalidades de segurança do próprio sistema operacional para uma proteção integrada. Limito Permissões: Concedo apenas o acesso essencial para aplicativos e contas.

Securing the operating system will be done at 2 levels: 1. User Level 2. Kernel Level User Level: 1. Define protection space, improve the resource access requests through some IPC mechanisms, add a security scan before entering into the kernel space and return from user space only this will save lot of time in context saving/restoring, validate user provided inputs thoroughly. Kernel space: 1. Limit the entry points to the kernel. 2. Marked critical resources access under the highly privilege trap table.

Securing an operating system without compromising performance requires a fine balance of proactive measures and efficient tools. First, prioritize regular updates for your OS and applications to patch vulnerabilities. Use lightweight, behavior-based antivirus solutions that detect threats without consuming excessive resources. Additionally, manage startup programs and background processes to ensure optimal boot times and smooth system operation. For advanced users, enabling OS-level virtualization or sandboxing adds an extra layer of security without affecting speed significantly. Security doesn’t have to mean sacrificing performance—smart strategies make all the difference.

One thing that is important is to be in the latest upgrades of the systems, in any OS, the most important is that because they are constantly fixing new vulnerabilities. Use a strong password without a coincidence of any private dates. No into any link, any can be suspicious. The first is to scan that if it's safe.

Protecting your operating system without sacrificing performance might seem challenging, but it's possible to balance security and speed with a few simple practices: - Keep everything updated: Regularly update your operating system and installed programs to fix security vulnerabilities. - Choose lightweight antivirus software: Pick a reliable antivirus program that won't slow down your computer. - Review startup programs: Disable programs you don't use often to improve boot time and overall performance.

Proteger o sistema operacional sem prejudicar seu desempenho pode parecer um desafio, mas é possível equilibrar segurança e performance com algumas práticas simples: - Mantenha tudo atualizado: Atualize regularmente o sistema operacional e os programas instalados para corrigir falhas de segurança. - Escolha um antivírus leve: Opte por um programa de proteção eficiente, que não deixe seu computador lento. - Revise os programas que iniciam junto com o computador: Desative aqueles que você não usa com frequência para melhorar o tempo de inicialização e o desempenho geral.

As a fresher, I would secure the operating system by implementing essential security measures while ensuring minimal performance impact. I’d start with updating all software and applying security patches. Enabling built-in firewall and antivirus tools provides a basic layer of protection. Using lightweight security software ensures system performance remains optimal. Configuring user account controls and permissions helps prevent unauthorized access. Regularly scanning for malware and optimizing system settings can enhance security without compromising speed. Additionally, educating users on best practices and secure behaviors is crucial to maintaining a secure and efficient OS environment.
