Vous devez protéger les données sensibles de votre entreprise. Comment construire un réseau de cybersécurité ?

Here's a strategic approach: Assess and prioritize risks: Conduct a comprehensive risk assessment to identify potential threats and vulnerabilities to your company's sensitive data. Design a defense-in-depth strategy: Implement a defense-in-depth approach to cybersecurity, layering multiple security controls and measures to protect your network from various threats. Encrypt sensitive data: Use robust encryption algorithms and secure communication protocols to ensure the confidentiality & integrity of data transmissions. Monitor and detect threats: Utilize security information & event management (SIEM) systems, intrusion detection systems (IDS), and endpoint detection and response (EDR) solutions to detect and mitigate threats effectively.

Building a cybersecurity network to protect your company's sensitive data involves a combination of technological solutions, policies, and practices to defend against cyber threats. Here's a strategic approach to constructing a robust cybersecurity network: Assess Your Current Security Posture Develop a Comprehensive Security Strategy Implement Strong Access Controls Deploy Defensive Technologies Monitor and Respond to Threats Educate and Train Employees Backup and Disaster Recovery Stay Compliant with Regulations Constructing a cybersecurity network is an ongoing process that requires continuous assessment, improvement, and adaptation to emerging threats.

The first step should be identifying the data sets that is to be protected. - What datasets ? - Where is my data ? - What is the security posture of the data? - What apps and processes use those data - segregate data in cloud and on premises and data that is being shared with 3rd parties Answer to above questions will help organizations follow the comprehensive data security plan and achieve compliance

To construct a cybersecurity arrange for ensuring delicate company information, begin with a comprehensive chance appraisal to distinguish vulnerabilities. Execute multi-layered guards counting firewalls, interruption discovery frameworks, and encryption. Set up strict get to controls, implement solid watchword approaches, and conduct customary security preparing for representatives. Utilize progressed endpoint security, frequently upgrade computer program, and perform visit security reviews. Finally, have an occurrence reaction arrange in put to quickly moderate any breaches.

Start by identifying and evaluating the cyber threats your company faces. Understand the data you have, its storage, transmission, access, and potential impacts if compromised. Analyze the threat landscape, including attacker types, motives, capabilities, and methods. Utilize frameworks like NIST or ISO to guide risk assessment and establish cybersecurity goals and priorities.

After assessing risks, apply security controls to prevent, detect, and respond to cyber threats. These controls include administrative (rules and guidelines), technical (hardware and software), and physical (locks and barriers) measures to safeguard data, systems, and networks.

There are three types of Security Controls Physical , Technical and Administrative Physical security like CCTV cameras, Access control , Alarm and Locks Technical controls like all software and hardware needed to secure the network like Firewalls , IDPS, NAC, SIEMs, EDR , SOCs , etc Administrative control like rules and governance that used to rule or govern your firm

You cannot fight what you cannot see That mean you have to make all attacks , threat visible and that can happen by effective monoitorying and analyzer tools SOC and NOC are now essential part of any comany SOCs focus on security, while NOCs focus on network operations. SOCs use security tools to monitor threats, while NOCs use network management tools to monitor network performance.

Regularly monitor and test your network to ensure security controls are effective. Analyze data for anomalies and vulnerabilities, conduct tests like penetration testing, and use results to enhance security.

Train staff on cybersecurity best practices to boost defense against threats. Foster a culture of security awareness and encourage incident reporting.

This is the most important part of cybersecurity. People are the weakest link in cybersecurity. They are chronically responsible for the failure of security systems. Everything begins and ends with people. It’s not necessary to possess advanced knowledge; rather, starting from the basics is crucial, since many people unknowingly violate fundamental principles of cyber hygiene.

Engage stakeholders internally and externally to foster collaboration on cybersecurity. Communicate policies and expectations while sharing insights and learning from others' experiences.

Continuously evolve and innovate your cybersecurity network to meet evolving threats and business needs. Stay informed about emerging trends and technologies, and be open to adopting new solutions and approaches. Embrace innovation and creativity to enhance your security posture and adapt to changing circumstances.

The information here is summarised from a generative point of view. Start with EDM and ERM policy, drive classification, discuss access control then drive data lineage, understand the flow of your data and bring in the controls like encryption, retention, monitoring etc. Your ERM will create the wider piece that covers sensitive data on assessing the risk, the mitigation you put in place and include data privacy across geo specific requirements. Then don't forget IR and BCP. Your EDM and EDR policies should compliment each other and remember to review these at least annually.
