What is the best way to ensure your operating system is always secure? (2024)

Maintaining a consistently secure operating system involves a structured approach to updates. But, testing updates and patches in the testing environment is always recommended. Schedule automatic checks for updates using the built-in update manager, but avoid unverified third-party tools for OS updates & patches. Schedules at convenient times to ensure minimal disruption to daily operations; monitor the update process for failures or errors.Also, perform Application, Driver, and Firmware Updates to prevent compatibility & security issues.More Importantly, Backing up before deploying major updates and maintaining a secure system by consistently updating OS to ensure system stability, reduce vulnerabilities, and optimize performance.

Having a patching strategy and take the time to automate the system hardening. A good tool for that is Ansible.The patching strategy usually involves having a testing environment to apply the patches or updates and test that has no ill effects and then deploying the patch or update to the actual servers in production.The patching strategy should have a define schedule and consider as well zero day vulnerabilities that may require a more agile process.

System,s update and enable firewall and strong password Always use secure softwares and configure your searching browser security

Install patches for the operating system and upgrade outdated operating systems. Give the least privilege access to users to perform their duties. Have a security operations centre team looking out for outliers in the logs.

Being intentional and following best practices such as keeping software updated, use strong authentication, install and automatically update antivirus software, back up your data in a frequent and routine manner, limit privileges, encrypt data at rest, use secure protocols and use a firewall to control ingress/egress points.

Implementing and configuring a Firewall, either Hardware or Software-based, is vital to ensure OS and application security.Selecting a firewall solution that suits the organization's needs, whether OS default or a custom firewall with advanced features. Define network security policies, specifying protection needs, potential threats, and access control rules.Set up rule-based filtering for both inbound and outbound traffic (TCP/UDP). Regularly update firewall rules to adapt to network changes and potential threats. Configure it to filter and block unwanted content and malicious packets. Enable logging and monitoring to track network activity.Keep your firewall software up-to-date with the latest security patches and updates.

Firewall must be configured to each infrastructure.Basics firewall will do most of defense from bots and hackers, advanced configuration will give power and performance to the firewall, establish IPsec in most connections, blocking undesired traffic and web scans.

Enforce policies. Do not use personal hardware in your company. Wireless is usually not a good option. Secure physical access to the network. Use paper shredder in case you want to get rid of documents which contain sensible data.

The layered approach in information security is crucial to mitigate cyber risks. Next-generation firewalls, though crucial, should not be seen as the sole line of defense. By adopting the onion theory, we recognize that a holistic approach, encompassing advanced technologies, user education, and robust security policies, is necessary to tackle constantly evolving threats. It's crucial to alert executives about the illusion of single-security provided by a lone solution. Investing in diversified and balanced measures, considering the human factor, ensures more effective protection against cyber threats. Security is an ongoing journey that requires constant awareness and adaptation to the complexities of the threat landscape.

By employing reliable antivirus and anti-malware, staying updated, conducting regular system scans, and practising safe online behaviours, you significantly enhance your operating system's security against various threats.Select the reputable vendor's antivirus and anti-malware according to your requirements by ensuring the regular latest virus database definition updates for new threats. Keep the software updated for security patches to effectively detect and combat new threats. Permanently activate real-time scanning to monitor files and system activity. Choose and train people for Safe Browsing practices. Enable Email Security filters and caution when handling email attachments or links to prevent malware from spreading.

Antivírus companies deliver major trojan scans daily, and are the best way to protect systems. The continuous scan will keep the system safe and up to date.Don't forget to configure AV to get the latest security updates.

Password policies should require users to create strong passwords and change them regularly. A password manager can help users to create, store, and manage strong passwords. MFA adds an extra layer of security by requiring users to enter a code from their phone or another device in addition to their password. System administrators can monitor user activity to identify suspicious activity, such as multiple failed login attempts or unusual access patterns. Finally, system administrators should educate users about security best practices, such as how to create strong passwords, how to identify phishing emails, and how to report suspicious activity.

The wrong use of passwords with common words or dates that could relate to your private info, can work with MFA. Authentication with two devices will add an extra account login. Only an hacker with access to both devices will successed.

Proteger suas contas e senhas é essencial em um mundo digital interconectado. Elas são chaves para seus sistemas, exigindo medidas de segurança robustas. Use senhas fortes, altere-as regularmente e evite a reutilização. Considere um gerenciador de senhas para armazenamento seguro. Adote a autenticação multifator (AMF) para uma camada extra de segurança, exigindo código, token ou fator biométrico. Evangelize essa prática no âmbito profissional e pessoal, promovendo o uso consciente de cofres de senhas e gerenciamento de acesso.

Here are some more tips and tricks to keep your system secure.• Physically clean your system.• Keep your battery health in check.• Avoid charging your laptop battery to 100% or draining it to 0%.• Keep the system shut down when not in use.• Perform disk cleanup regularly.• Minimize unnecessary settings on the laptop.• Always install stable OS versions or releases.• Keep your system software updated.• Regularly perform virus checks.• Always connect to a trusted network or Wi-Fi.• Do not connect untrusted devices to the system. Always connect trusted or genuine devices to the system.• Restart your systems regularly.• Do not overload system performance or application usage on the laptop.• Always maintain data backups.

In design phase, integrate OWASP principles like threat modeling and encryption to mitigate risks early.Validate inputs, parameterize queries, enforce authorization in code to prevent injection.Leverage platform tools like encoded passwords and hashing Limit dependencies and access scopes to minimize attack surface.Include security testing in sprints. Scan for vulnerabilities in each release. Remediate findings prior to deployment.Enable logging and monitoring in production to detect issues like elevated error rates.Use runtime application self-protection to detect and block threats.Collaborate cross-functionally to apply best practices like OAuth and SAML.Stay current on risks like XSS, CSRF through training and research.

Automate UpdatesAutomating updates is essential for maintaining a secure operating system. Ensure that your system is configured to automatically download and install security patches and updates as soon as they are available. This reduces the risk of missing critical updates that could leave your system vulnerable. Additionally, use automation tools to regularly check for and apply updates to all software and dependencies. This proactive approach helps maintain security without relying on manual processes, ensuring your system stays protected against known threats and vulnerabilities.

Implementing honeypots/Honeynets security mechanism creates a virtual trap to lure attackers. Learn attacker's patterns and mitigate against them. Also, add the Intrusion Detection and Prevention System. Also, consider the user perspectives; they can also be the unintentional part of comprising the system.Also, educate the non-technical end-users by conducting basic security trainings and sessions.

Server 100% secured when he stopped and disassembled. In real life you can only apply different security layers and make hacking process too complicated and not relevant. Antivirus, updates, firewalls, network segmentation, correct users and authorization/authentication management, WAF, proxy... Huge and expensive topic.

Ensuring the security of the operating system is crucial for the protection of the computer from potential threats. However, it is necessary to implement collectively all measures such as keep the system updated, use strong and unique passwords, enable a firewall, install and update antivirus software, be cautious when downloading or installing software, regularly back up data, enable automatic updates for applications, be mindful of phishing attacks, disable unnecessary services, and continue to educate yourself.Stay active, always.
