• Secure Your Network Infrastructure

Ensuring the security of your network infrastructure is paramount to prevent unauthorized access and data breaches. It is essential to use a combination of security measures to achieve this. Firewalls, secure routers, and intrusion prevention systems should be deployed to safeguard the network perimeter. 

These devices act as the first line of defense, monitoring and controlling incoming and outgoing network traffic. Regularly updating and configuring these devices is crucial to ensure they are optimized for security and capable of defending against evolving threats. Implementing network segmentation and encryption protocols can also add more protection to your network infrastructure. 

Network segmentation involves dividing the network into smaller, isolated sectors and limiting the potential impact of a breach. Encryption protocols, such as secure socket layer (SSL) or transport layer security (TLS), encrypt data as it travels across the network. This makes it more challenging for attackers to intercept and exploit sensitive information.

• Implement Strict Access Controls

Organizations should implement strict access controls to ensure only authorized individuals have the necessary privileges. Access should be granted on a need-to-know basis, meaning that users are given the minimum access required to perform their job functions. This reduces the risk of unauthorized access or accidental exposure of sensitive information.

Regularly reviewing user access rights is essential to promptly identify and address any discrepancies or vulnerabilities. User accounts no longer needed or associated with individuals who have left the organization should be deactivated promptly. 

Implementing multi-factor authentication (MFA) for critical systems also adds an extra layer of security. MFA requires users to provide multiple forms of authentication, such as a password and a unique verification code sent to their mobile device, further mitigating the risk of unauthorized access.

NTM’s expertise in multi-factor authentication (MFA) ensures that the risk of unauthorized access is reduced even if passwords are compromised.

• Conduct Regular Security Audits

Periodic security audits are crucial in identifying vulnerabilities and gaps in existing security measures. These audits involve comprehensive network infrastructure, applications, and systems assessments to uncover potential weaknesses. Conducting these audits regularly allows organizations to proactively identify and address security vulnerabilities before malicious actors can exploit them.

During a security audit, various techniques are used, such as vulnerability scanning, penetration testing, and code review, to assess the effectiveness of existing security controls. Any identified issues or weaknesses should be promptly addressed to fortify the security posture. This may involve applying software patches, updating configurations, or implementing additional security measures.

Regular security audits ensure that security measures remain effective and current. They provide organizations with valuable insights into their security posture, enabling them to strengthen their defenses against cyber-attacks.
