You've launched a live website. How do you keep security vulnerabilities in check?

To keep security vulnerabilities in check after launching a live website, regularly update both the security measures and the application itself. This means ensuring all software, including frameworks and libraries, are up-to-date to patch known vulnerabilities. Applying security patches as soon as they are released. Using monitoring tools to detect suspicious activities and potential breaches, here you may try out, Nagios, Splunk, etc. Conducting periodic penetration testing to identify and fix vulnerabilities. Regular backup and educating the team on the latest security practices and threat is the most important thing to do.

To prevent security vulnerabilities after your site goes live, ensure that all software tools used for development are kept up-to-date. Use complex passwords and activate two-step verification for administrator accounts. Regularly back up your website and store these copies securely. Ensure your site is HTTPS certified for encrypted communications. Conduct regular security checks and scan for possible threats using tools such as OWASP ZAP or Nessus, while continuously monitoring for any suspicious behavior.

To maintain security after launching a live website, it's essential to regularly update both security protocols and the application itself. This involves keeping all software, including frameworks and libraries, current to address known vulnerabilities. Implement security patches promptly upon release. Utilize monitoring tools like Nagios and Splunk to detect unusual activities and potential breaches. Conduct regular penetration testing to discover and rectify vulnerabilities. Ensure you perform regular backups and educate your team on the latest security practices and emerging threats.

After launching a live website, it's crucial to prioritize security to prevent hacking and data breaches. Here are some essential measures to keep security vulnerabilities in check: Regularly update software and plugins: Ensure all software, plugins, and themes are up-to-date to prevent exploitation of known vulnerabilities. Use strong passwords and 2FA: Enforce strong passwords and enable two-factor authentication to prevent unauthorized access. Monitor website activity: Keep a close eye on website activity, including login attempts, file changes, and error logs. Keep sensitive data encrypted: Ensure sensitive data, such as passwords and credit card numbers, are encrypted and stored securely.

From my experience, I can share a crucial piece of advice: never use the same password on multiple platforms. Always create unique passwords for each account. Avoid saving passwords in your Google account, as this poses a high risk if your account is compromised. Instead, enable two-factor authentication (2FA) wherever possible and regularly update your passwords, ideally once a week. Write down your passwords in a personal notebook rather than saving them in digital notes or images on your device. This approach ensures your passwords are safe and secure.

My most preferred security measure when securing passwords is a combination of salting and hashing with a twist on the frontend. What do I mean by a "twist"?? I'd ask the users to use pass-phrases instead of passwords and they must be 9 characters long. This still isn't secure cause with a quantum computer, hackers would decrypt all the information in a short amount of time but since my clients don't work for governments, they aren't really at risk for now.

I would strongly advise against using the same password on different platforms based on my own experience. Make sure each account has a unique password. In order to reduce the likelihood of your Google account being hacked, avoid storing passwords there. Set up two-factor authentication (2FA) instead, and change your passwords frequently—ideally once a week. Rather than storing your passwords in electronic files or photos on your phone, write them down in a personal journal. Your passwords will stay safe and secure if you use this method.

Implement and enforce strong password policies across all access points. Use password managers like LastPass for team access. For user authentication, consider implementing multi-factor authentication (MFA) using services like Auth0 or implementing WebAuthn for passwordless authentication. Regularly rotate sensitive credentials, especially for database and API access.

Cryptography is essential to safeguard sensitive information on my website, ensuring all data transfers are secure. Implementing Secure Sockets Layer (SSL) encryption is vital, especially for handling financial transactions or personal data. Beyond just securing connections, SSL certificates build trust with visitors by demonstrating a commitment to privacy. Leveraging my extensive experience in high-profile projects and robust application development, I prioritize strong security measures and streamlined developer workflows, emphasizing both accessibility and user confidence.

Protect sensitive data by implementing SSL/TLS encryption for all communications between the server and clients. Ensure that your SSL certificate is valid and up-to-date. For data at rest, use strong encryption algorithms for storing sensitive information in your database.

In my case when using react and express, for securing a backend what I generally do is that I restrict the requests for all the url using cors and allow only the url of my frontend. Additionally I use frontend as well as backend validation and hashing also.

As an experienced website developer, I can't stress enough the importance of strong, unique passwords as your first line of defense against unauthorized access. Every account tied to your website—from hosting and database access to admin logins—should use complex, hard-to-guess passwords. I recommend using a password manager to generate and securely store these passwords. Additionally, always implement two-factor authentication (2FA) to add an extra security layer. Regularly update passwords and ensure they are never reused across different platforms. By adopting these practices, you greatly reduce the risk of breaches and ensure your website remains secure.

Una vez que has lanzado un sitio web en vivo, es fundamental mantener las vulnerabilidades de seguridad bajo control: ✅Certificados SSL/TLS: mantén actualizados los certificados SSL/TLS y asegúrate de que estén correctamente configurados. ✅Implementar HTTPS: asegúrate de que todo el tráfico entre los usuarios y el servidor esté cifrado utilizando HTTPS. ✅Cifrado de datos en la nube: si utilizas servicios en la nube, asegúrate de que los datos también estén encriptados en tránsito y en reposo.

Having regular backups of your website data is very important. Even with strict security standards, unwanted events like new security vulnerabilities or data loss can occur. Set up automated backups of your website or data to ensure you always have a recent copy. Store these backups in a secure, offsite location or use cloud storage with encryption. Test your backups regularly to make sure they are complete and not corrupted, ensuring they can be quickly restored if needed. Keep clear documentation of your backup and restoration procedures to help with quick recovery during emergencies.

Make regular backups of your website's data and store them in a safe location. To make sure they can be restored in the event of data loss or a security incident, test them on a regular basis. These backups facilitate speedy recovery from security incidents and act as a layer of protection.

Realizar copias de seguridad periódicas es una de las prácticas clave para asegurar que tu sitio web pueda recuperarse de cualquier incidente de seguridad: ✅Automatización de copias de seguridad: configura un sistema automatizado que realice copias de seguridad regulares de tu base de datos y archivos del sitio web. ✅Pruebas de restauración: regularmente realiza pruebas de restauración para asegurarte de que las copias de seguridad se puedan recuperar correctamente y en el menor tiempo posible. ✅Monitoreo y alertas: implementa un sistema de monitoreo que te notifique si una copia de seguridad falla o si no se ha realizado según lo programado.

Ensuring that your website's data is backed up frequently is crucial. It allows you to quickly restore your site to its previous state in case of an attack or data loss. Schedule automated backups and store them in multiple locations, both on-site and off-site. Regularly test your backup restoration process to make sure everything works smoothly when you need it most. By making regular backups a part of your security routine, you can safeguard your website against potential threats and maintain peace of mind.

Implement continuous security monitoring to detect and respond to threats in real-time. Use tools like intrusion detection systems, firewalls, and security information and event management (SIEM) solutions. Regularly review logs and alerts to identify and address potential security issues promptly.

Set up intrusion detection systems (IDS) and web application firewalls (WAFs). Monitor logs for suspicious activity and respond promptly to any alerts.

Stay informed about the latest security threats and best practices. Participate in security training and follow reputable sources for updates on emerging vulnerabilities. Ongoing education helps you stay proactive in identifying and mitigating security risks.

As a sysadmin for a live website, I stay vigilant about security threats. Recently, I learned of the "regreSSHion" vulnerability affecting certain OpenSSH servers. To stay informed, I regularly monitor security mailing lists, CVE databases, and vendor announcements. When new vulnerabilities emerge, I quickly assess their impact on our infrastructure and prioritize patches. This proactive approach is crucial for maintaining our website's security in an ever-evolving threat landscape.

Stay informed about emerging threats and best practices. Learn about common attack vectors like cross-site scripting (XSS), SQL injection, and cross-site request forgery (CSRF).

It's not necessary that you use native solutions, there are a wide range of companies that have already been doing this for years and have been successful in them. Just integrating these solutions would take off a lot of burden as well as keep your security intact. Also, adding the smallest type of securities and following the basic fundamentals of securing your website such as using Authentication, CORS, CSRF and so on are very vital.

In light of recent events like the Polyfill[.]io attack, it's crucial to assess and mitigate supply chain risks. Regularly audit third-party scripts and libraries used in your application. Consider self-hosting critical dependencies or using subresource integrity (SRI) checks. Implement Content Security Policies (CSP) to restrict which sources can load content on your site, helping to prevent malicious script injections. In case your organisation uses docker consider implementing docker scout to proactively enhance your software supply chain security.

Run your websites on CDN: They act as a secure proxy between a user and the origin server. They also help in mitigating DDoS attacks & other cyber security threats

Implement multi-factor authentication (MFA) to add an extra layer of security to user accounts. Conduct periodic security audits and penetration testing to identify and fix potential vulnerabilities before they are exploited. Use web application firewalls (WAF) to filter and monitor HTTP traffic between your website and the internet. Stay informed about new security patches and vulnerabilities by subscribing to security bulletins and advisories. Ensure secure configuration of all servers and services, including disabling unnecessary features and services that could be exploited.
