You’re responsible for network security. How do you ensure your protocols are up to date?

To ensure network security protocols are up to date, regular scanning of the network is essential. This involves using specialized tools and software to conduct vulnerability assessments and penetration tests to identify potential weaknesses in the network infrastructure. By scanning the network regularly, security professionals can detect any outdated protocols, misconfigurations, or vulnerabilities that could be exploited by attackers. Additionally, staying informed about the latest security advisories, patches, and updates from vendors and security communities helps in promptly addressing any security gaps and keeping protocols up to date.

1. Access Control to System (Limit privileged user accounts) 2. Network Compliance with always the latest standards 3. Awareness must be carried out in the workplace 4. Physical Security to Network Devices must be monitored

To ensure network protocols are up to date: Stay updated on security vulnerabilities from reliable sources. Regularly apply software updates and patches released by vendors. Subscribe to vendor notifications for immediate alerts. Conduct vulnerability scans to identify outdated protocols. Audit network configurations and remove deprecated protocols. Implement security best practices and industry standards. Segment the network to minimize potential breaches. Provide continuous education and training for the security team. Perform regular security assessments and penetration testing. Have an incident response plan and monitor the network for anomalies.

1. Regularly conduct comprehensive assessments of current security infrastructure 2. Stay informed about latest developments and best practices in cybersecurity 3. Actively participate in industry forums, attend conferences, and pursue professional certifications 4. Communicate and provide ongoing training to team members about security protocols and procedures 5. Foster a culture of security awareness within the organization

- Staying informed of new developments and instantly trying to analyze your network for the same vulnerabilities and fixing it. - Periodic scanning of the network with a good tool that is trusted and is a industry standard - Updating the protocols in a canary based manner in-order to prevent the downfall of the entire system. Updating to the latest and greatest is not always possible and is not reliable as there might be some regression.

To ensure that our network protocols are up-to-date, we regularly review them for any known vulnerabilities and apply patches or updates. Additionally, we stay informed about the latest security trends and best practices to ensure our protocols are robust against emerging threats. This involves monitoring security advisories, participating in security communities, and conducting regular security audits.

Industry best practices serve as a benchmark for security standards. They represent the collective wisdom and experience of experts in the field, distilled into actionable guidelines. Following these standards ensures that your organization meets a certain level of security maturity and reduces the risk of vulnerabilities.

Staying aligned with industry best practices is akin to having a roadmap. Adhering to established guidelines provides a benchmark for security standards and helps in implementing proven strategies that evolve with emerging threats.

Consultar e seguir essas orientações do setor é uma maneira eficaz de garantir que os protocolos de segurança estejam alinhados com as últimas recomendações e que a rede esteja protegida contra ameaças emergentes.

We should usually have the list of services that the organisation uses for day-to-day operations, Configuring them on the basis of SECURITY COMPLIANCE standards helps in removing any config-related vulnerabilities

Constant monitoring is a must, as this helps in getting a birdseye view using dashboards, and then you check granular details, Many tools offer dashboards, however using SIEM tools provides more granular insights as you do not want to login to all the tools just for monitoring, it's better to integrate and check everything at one place. Specifically, first remediating vulnerabilities that are exploitable due to config helps. Enabling automatic updates is a easy an effective way to ensure that your network is secure.

I usually check on needed updates and fix the existing vulnerabilities through a deep scan through my cyber security solution which solves any existing vulnerabilities by installing the needed patches and hot fixes.

From my perspective, vigilantly monitoring and updating network devices is paramount for ensuring robust protocols and security. Regularly checking routers, switches, firewalls, servers, and other devices for firmware or software updates is essential to enhance functionality and address security vulnerabilities promptly. Enabling automatic updates or scheduling them for convenient times streamlines the update process. Additionally, replacing or upgrading unsupported or incompatible devices is crucial to maintaining protocol compatibility and bolstering network resilience. This proactive approach safeguards against potential exploits, enhances system performance, and reinforces overall cybersecurity posture.

Again keeping up with updating every instance within the network, scanning for security vulnerabilities/ breaches and looking for updates/ patches/ fixes to close them.

Updating devices ensures seamless interoperability and reduces compatibility issues. It may also reduce the risk of security breaches or compliance violations

User education is a must, as many times organisations are hacked due to user negligence towards security, It is better to set a quarterly call with end users and make them aware about the best practices as per your organization

Many security breaches occur due to human error or social engineering tactics. Educated users are less susceptible to phishing attacks, malware downloads, or accidentally compromising security measures. Educating users on creating strong passwords and proper password management practices. Conduct simulated phishing attacks to test user awareness and effectiveness of training. This helps identify areas where users need further education and reinforces best practices. Develop clear, concise, and easy-to-understand security policies that outline user responsibilities and acceptable usage of the network.

Conduct regular security training sessions to educate employees about cyber security best practices and test the effectiveness of incidents responsive procedures

The security of a network is directly influenced by the actions of its users. Even with robust security measures in place, the network remains vulnerable to breaches if users do not adhere to best practices or remain vigilant against potential threats, hence proactive training and reviews of current practices are essential

I agree that educating end users is a necessity. However, setting up education plans for them without follow-up and accountability, is setting everyone up to fail. Too many times, I have seen money spent on phishing campaigns, pen-testing, policy implementation, etc., only to see them fail because "it doesn't matter if we don't comply/do the education". Unfortunately, IT education seems to be near the bottom in priorities.
