Network security strategies in the new digital era

The reliance on technologies and the number of cyber threats continue to grow, making it crucial to implement robust and up-to-date cybersecurity strategies to protect data and ensure continuity of operations. In this article, we cover the benefits of investing in your company's network security, examples of cyber threats, and strategies that can be applied.

What does network security cover?

Cyberattacks are increasing in number and sophistication around the world. This trend is expected to be accentuated. According to IDC, it is predicted that by 2025, 41 billion devices worldwide will be connected to the Internet of Things (IoT), increasing the number of devices used in everyday life to provide data that could be a target for a cyberattack.

Network security involves policies and practices aimed at combating cybercrime. Among its objectives, the prevention and monitoring of unauthorized access, misuse, modification or interruption of a computer network and the resources accessible through it stand out. Ensuring network security is essential to protect both business and personal data, as a crucial line of defense against information loss and service disruption.

Benefits of network security

• Protection of sensitive data: prevents unauthorized access to confidential information.
• Business continuity: minimizes the risk of operational disruptions caused by cyberattacks.
• Business reputation: protects the company's image before customers and partners.
• Regulatory compliance: ensures that the company is compliant with safety standards and regulations.

Main threats

• Malware: malicious software that can damage, disable systems, and/or steal data.
• Phishing: attempts to obtain sensitive data by disguising themselves as trusted entities.
• Ransomware: a type of malware that encrypts data and demands a ransom to release it.

Impact of cyber threats

• Data loss: important information can be destroyed or stolen.
• Service disruption: attacks can bring critical operations to a standstill.
• High costs: recovery and redemption expenses can be high.
• Reputational damage: damage to or loss of trust of customers and partners.

Network security strategies

• Secure authentication: use systems to ensure only authorized people can access the network.
• Firewalls and intrusion detection systems: create barriers and monitor the network to identify and neutralize suspicious activity.
• Data encryption: protecting sensitive data during transmission and storage, making it inaccessible without the correct key.
• Safety and training policies: ensuring that employees are aware of the risks and adopt safe practices.

Emerging technologies in network security

• AI and ML: these technologies enable proactive threat detection and automatic incident response, analysing large volumes of data to predict attacks.
• Cloud security: with the increased use of the cloud, it's vital to protect data with encryption and identity management.
