In today’s hyper-connected world, networks and email systems are prime targets for cybercriminals. Unauthorized access, data breaches, and phishing attacks can cripple businesses and compromise sensitive information. Network and Email Security (NES) is not just a best practice it’s a necessity.

This post explores key strategies to safeguard your organization’s communication channels and prevent cyber threats.

Why NES Matters

Networks and email systems are the backbone of modern business operations. A single vulnerability can lead to:

• Data Loss: Confidential information falling into the wrong hands.
• Financial Damage: Costly breaches and ransomware attacks.
• Reputation Risk: Loss of customer trust and brand credibility.

FinSequr’s NES Best Practices

NES.1: Deploy and Configure Firewalls

Firewalls act as gatekeepers for your network. To maximize protection:

• Install firewalls at the network perimeter.
• Enable host-based firewalls on individual devices.
• Regularly audit and update firewall rules to block unauthorized traffic.

NES.2: Secure Wireless Connectivity

Wi-Fi networks are often the weakest link. Strengthen them by:

• Using WPA2/WPA3 encryption.
• Setting strong, unique passwords and hiding SSIDs.
• Avoiding factory-default credentials.
• Segregating guest networks from internal systems.
• Preventing endpoints from auto-connecting to public Wi-Fi.
• Enforcing secure wireless configurations across all devices.

NES.3: Implement VPNs for Remote Access

Remote work introduces new risks. Combat them with:

• VPNs that encrypt all traffic.
• Multi-Factor Authentication (MFA) for added security.
• Regular monitoring of VPN logs to detect anomalies.

NES.4: Protect Email Systems from Phishing

Email remains the most exploited attack vector. Secure it by:

• Configuring SPF, DKIM, and DMARC to prevent spoofing.
• Training employees to recognize phishing attempts.
• Deploying advanced email filtering solutions.
