Your company's network is vulnerable to cyber attacks. What are you doing to protect it?

Acá un enfoque conciso: 1. Inventario de Activos: Identifique y clasifique activos de red. 2. Amenazas y Vulnerabilidades: Analice amenazas potenciales y realice escaneos de vulnerabilidades. 3. Políticas y Controles: Revise políticas de seguridad, controles de acceso y cifrado. 4. Monitoreo y Detección: Evalúe capacidad de detección de actividades sospechosas. 5. Parches y Actualizaciones: Verifique implementación oportuna de parches de seguridad. 6. Educación y Concientización: Refuerce conciencia sobre seguridad entre empleados. 7. Respuesta a Incidentes: Asegúrese de tener un plan de respuesta a incidentes sólido. 8. Auditorías de Seguridad: Realice auditorías regulares de seguridad internas o externas.

Securing a company's network from cyber attackers involves implementing a combination of technical and procedural measures. 1. Firewall Implementation and Regular Monitoring: Deploy a robust firewall to monitor and control incoming and outgoing network traffic. 2. Employee Training and Awareness: Conduct regular cybersecurity training for employees to raise awareness about potential threats and best practices. 3. Regular Software Updates and Patch Management: Ensure that all software, including operating systems and applications, is regularly updated with the latest security patches.

Start from the Architecture, most of the problems are solved or created here. Cyber attacks are a reality and one should be prepared well in advance with preventive and reactive plans. There are 2-3 main areas that are resposible for 80-90% of attacks. Divert your focus on the following: 1. All the public facing endpoints need to be behind WAF or similar security services. Make sure your LB's are guarded. 2. Scan your endpoints peridically, it cant be ontime task. 3. Make sure no privilaged software is running on your network and is also publically accessible with VPN 4. No CICD without VPN

To safeguard my company network, I will employ robust firewalls and Intrusion Prevention Systems, control traffic meticulously, and regularly update software for the latest security patches. Network segmentation, strong user authentication, and continuous monitoring add layers of defense, while encryption safeguards sensitive data. Security audits, employee training, and a well-defined incident response plan further strengthen our resilience. Regular data backups and testing restoration processes ensure business continuity, creating a comprehensive defense against cyber threats.

Debe abstraerse de que se trata de un sistema de información, debe pensar de una catástrofe que anule su capacidad de operar con su empresa, cuando cobre conciencia de esa situación estará en condiciones de evaluar los riesgos y estará dispuesto a tomar las medidas necesarias para hacerlo de manera eficiente.

As you know, cyberattacks can damage our network and data, so we need to take some measures to prevent them. Here are some of the things we should do: -Make sure we have antivirus software on all our devices and keep it updated. -Use passwords that are hard to guess and have different types of characters. -Learn how to spot and avoid cyber threats like phishing, spyware, and ransomware . -Set up a firewall and anti-malware software to stop unauthorized access and detect suspicious activity . -Encrypt and backup our data to protect it from loss or theft . -Get cybersecurity insurance to cover the costs of possible breaches or damages . -Create a security-focused culture that supports best practices and regular audits .

Implementing network security measures is essential to protect your organization's digital assets and sensitive information from various cyber threats. Ensure that your network security measures comply with industry regulations and legal requirements. Regularly review and update security policies to align with changing compliance standards. Conduct periodic security assessments, penetration testing, and vulnerability assessments to identify and address potential weaknesses in your network security posture. Divide your network into segments to limit the impact of a security breach. Segmentation helps contain and isolate potential threats, preventing lateral movement within the network.

Create a firewall Isolate confidential information Create a demilitarized zone Develop an authentication scheme Develop an encryption system Develop a social engineering blocking system

-Take security as a top priority by having users have strong password of eight characters long with numeric,symbols ,special characters. -Identify all devices in the network and prioritize who has access to the network. -Make sure the firewall and antivirus are on devices and are up to date . -Make sure users are not sharing sensitive things like passwords and login credentials . -Sensitize people to cyber security best practices so as to ensure the cause of the attack was not because of lack of knowledge.

The key to implementing security measures is first understanding that at its core, cybersecurity is a people problem. So, start off by educating your administrators and users about best practices. Next, create and disseminate detailed secure configuration, patching, vulnerability scanning, and incident management procedures. Finally, execute those procedures with the understanding that security isn't a "once and done thing." Rather, it's an ongoing process requiring constant monitoring and refinement.

By continuously monitoring and analyzing network traffic, you can detect unusual patterns, potential security threats, and unauthorized access. Firewall Configuration: Ensure that your firewall is properly configured to filter and monitor incoming and outgoing traffic. Intrusion Detection System (IDS) and Intrusion Prevention System (IPS): Deploy an IDS and/or IPS to detect and prevent malicious activities. These systems analyze network traffic for suspicious behavior and can take automated actions to block or alert administrators. SIEM (Security Information and Event Management) Systems: Implement a SIEM system to collect,analyze,and correlate log data from various sources across your network. Tools like Splunk or ArcSight can be used.

The data collected during monitoring software must be analyzed in detail and interpreted. Especially at the point of making sense of this data, reaching the relevant error is very important in terms of taking precautions about this error. The importance of repeated mistakes in taking precautions in eliminating the risk in question cannot be taken for granted.

Whenever possible, it's crucial to have a NOC and a SOC in your organization to be constantly monitoring your network, devices, systems, and more, so that any threat or incident can be quickly detected and mitigated.

Si vous en avez la possibilité, achetez-vous un service SOC. Quelques compagnies proposent des services de surveillance (et parfois de réponse et correction) en H24. Si vous n'avez pas cette capacité à externaliser ce service, ne rognez pas sur les outils de surveillances intégrés dans vos outils de sécurité, et surtout configurez de vraies alertes. Stop aux remontées génériques qui vous polluent et que vous ne consulterez même plus au bout de quelques mois ...

Let's be honest: without an operational SOC, do not implement any security plan! Otherwise, it would be a big trouble very hard to maintain. Everything, I mean all assets and all services, MUST comply with our deployed SIEM to have its behaviour monitored. By operational, I mean an SIEM that has all steps of sdetecting uspicious behaviours already implemented: log gathering, considering security use cases, implementing security alerts, reports, and dashboards, orchestrating security events, etc.

- Conduct periodic phish simulation exercises and retest failures. - Implement User Awareness Training on topics like passphrases for passwords, how to identify potential phish emails.

Products like KnowBe4 are vital for educating end users about cybersecurity, and addressing the human factor in cyber threats. Using phishing simulations and providing continuous learning, KnowBe4 strengthens users' ability to recognize and resist tactics like phishing. Products and training like this help to foster cybersecurity awareness, emphasizing shared responsibility and accountability. We have seen a substantial change in culture since implementing their product. We have also changed the way our IT staff react to false phishing reports, we would rather someone report something than not.

Engage in casual conversations with your users, whenever you can. Don't immediately reproach them, and listen first. You'll hear things that will make your eyes roll and will boil your blood, but you have to keep it cool. By listening, you'll know very well what are your worst security shortcomings.

User awareness is critical in maintaining network security. I will organize regular training sessions for all network users, educating them about safe online practices, recognizing phishing attempts, and using strong passwords. This security aspect is often the first line of defense against cyber attacks.

here are Some examples of modules that the training sessions could contain : Module 1: Introduction to Cybersecurity Module 2: Identifying phishing emails Module 3: Secure Web Browsing Practices Module 4: Social Engineering Awareness Module 5: Password security and secure file handling. As a training method, we can combine several methods including: - Interactive online learning modules. - Phishing simulation exercises. - Group Discussions. - Real-life examples and case studies...

1. Scan the network to identify risks, vulnerabilities, and threats to the network 2. Keep ALL software and systems fully up to date 3. Enforce Endpoint protection 4. Ensure that all internal systems are protected by a firewall and that the firewall is configured properly. 5. Data backup 6. Control access to systems and all network elements 7. Enforce Access Management best practices 8. Enforce security policies 9. Multi-factor Authentication (MFA) and use of strong passwords 10. Continuously monitoring and analyzing network traffic 11. Deploy an IDS/IPS to detect and prevent malicious activities.

Pentest is different from a vulnerability assessment in the sense that vulnerability assessment identifies weaknesses and Pentest will test if the weaknesses can lead to exploitation. Pentest can't replace vulnerability assessment and vice versa. Both are important.

This proactive approach helps in identifying vulnerabilities and addressing them promptly. It's also essential to stay informed about the latest security threats and trends to anticipate and mitigate potential risks. Engaging in continuous improvement through training and awareness programs for staff can further reinforce network security, making it a resilient and dynamic defense against evolving cyber threats.

Effectuer des Évaluations et Audits de Sécurité Réguliers : Planifiez des évaluations de sécurité périodiques pour tester l'efficacité des mesures de sécurité en place. Réviser et Mettre à Jour la Politique de Sécurité : Examinez régulièrement la politique de sécurité réseau et ajustez-la pour tenir compte des évolutions technologiques et des nouvelles menaces. Apprendre des Expériences : Utilisez les retours d'expériences et les commentaires pour identifier et implémenter les améliorations nécessaires à la sécurité de votre réseau.

Regular testing of our network security is essential. I will conduct simulated attacks, like penetration testing, to evaluate the effectiveness of our security measures. These tests will help identify weaknesses, allowing us to improve our defenses continually.

Use a VPN to enable more privacy and security when remote accessing your company's system and help protect sensitive data . Protect your network by setting up firewall and encryption information. It's important to stay vigilant and keep up to date with latest cyber security trends and best practices.

I will implement strict control to minimise unauthorised access like RBAC or VPN . I will deploy advance firewall rules for prevention systems. Network segmentation to our network to limit the impact of potential breaches. I will utilise encryption for both data and at rest. I will proactively update the patch of system and application time to time and conduct the regular security audit and the monitoring. For the third party tool or vendor I will ensure that they follow security standards. For regular security I will conduct periodic testing and vulnerability assessment.

One big lack in cyber security is having a specific and formal organisational chart with defined roles and responsibilities for responding to cyber incidents. This chart should practice a clear and operational incident response process with fully documented tools. There should also be a ticketing system to bond the process and to provide management reports for all incidents.

Cyber attack should be immediately reported to concern cyber security officer. If required quarantine the device. Never click suspecious link

Strongly agreed on this and it is an important step that needs to follow once the device is attacked. If your device got attacked please do not hesitate to report to your cybersecurity team.

Focus on the fundamentals first. Once you have those down, the next thing to look at is credential and access exposure via the criminal underground. Every day, millions of credentials are shared in the criminal underground. If that weren’t bad enough, tens of millions of cookies a day are compromised. Cookies allow access after authentication, so MFA won’t help you avoid compromise due to cookie exposure. Many organizations have policies in place for remediating malware infections, but very few clean up the exposed credentials and cookies. This leaves the criminals with open access to secondary targets to attack. Network defenses today need to consider remediation of access exposure.

Consider your BYOD (Bring Your Own Device) policy carefully. Staff using their own devices on the company network can introduce security issues.

Contar con dispositivos móviles totalmente gestionados permite aplicar configuraciones de Red permanentes no modificables que disminuyen los riesgos vinculados a las redes. Usar APN privados, VPN per device y otras configuraciones permite canalizar todo el tráfico para que sea analizado y supervisado. #UEM #mobility #cibersecurity

If the server doesn't have to be exposed, do not expose it. Assess the risk carefully, and consider going on premise if the tool is business critical, your network admin can connect it to the support if and when you need it, it will be risk free and cheaper than all the protection you have to implement. Nothing is safer than offline.

Avant d'appliquer des règles de sécurité, il faut comprendre comment les collaborateurs travaillent, quels sont leurs besoins, quels sont leurs usages. Sécuriser un SI ne veut pas dire se transformer en Fort Knox et pénaliser les collaborateurs dans leur quotidien. Cela ne signifie pas non plus d'accepter des brèches béantes pour un usage spécifique mais apporter une analyse et expertise en sécurisant intelligemment l'usage.
