Network encryption protects your business against threats — and prevents data loss, unauthorized access, or disruptions in business.
There are plenty of things network encryption entails, such as:
We’ll now take a closer look at all of these — and help you create a bulletproof security strategy that minimizes the attack surface, minimizes potential security breaches, and eliminates any security flaws.
Let’s jump in!
Network encryption is an encryption tool for securing data you send over the network.
It protects you against unauthorized users and eavesdropping – so you can securely send confidential information.
There are two main reasons why you absolutely need network encryption:
Is your network secure – or are you allowing malicious actors to have unauthorized access that can potentially put your organization at risk?
To find out, check whether you’re leveraging these 19 best practices for network security.
There are different encryption methods/algorithms you can use to secure your data. For instance, some of the most popular algorithms include:
Which one you choose depends solely on your needs.
But even if you have an mathematical algorithm in place, we still recommend reviewing and updating it regularly, so you can be secured against the most up-to-date cybersecurity threats.
Establish a sound decryption process of key management strategy with the regular rotation of keys for encryption.
This practice ensures that even if a key is compromised, the impact is minimized, preserving the confidentiality and integrity of encrypted data over time.
WPA3 (Wi-Fi Protected Access 3) is the latest wireless security protocol for enhancing Wi-Fi security.
As an upgrade from WPA2, WPA3 provides stronger protections against offline dictionary attacks, making it significantly harder for brute-force attacks to guess passwords. You can see a great example of WPA3 in use with Wi-Fi hotspots, such as cafes. WPA3 protects users’ data from common vulnerabilities like man-in-the-middle attacks — even if no strong password is used for a network.
Deploying Virtual Private Networks (VPNs) is critical for securing remote access.
Configure robust authentication mechanisms and regular updates of VPN protocols to bolster defenses against potential vulnerabilities to remote connectivity.
Ensure effective data encryption on endpoint devices to protect sensitive information.
Full-disk encryption will provide you with solid protection — securing you against unauthorized access in the event of device theft or loss.
Having regular security audits is a MUST-DO.
Make timely adjustments to encryption protocols based on audit findings and enhance your network’s strength against threats.
Add access controls to restrict data access based on user permissions.
This ensures that only authorized individuals can access sensitive information — reducing the security risk of data breaches.
Employ robust email encryption process to protect sensitive info during email communication.
Additionally, carry out user training on how to recognize phishing attempts to enhance your security posture against email-related threats.
Deploy intrusion detection and prevention systems to monitor network traffic.
Use real-time analysis of network behavior to detect and respond to security requirements and threats — ensuring a proactive defense strategy.
To limit the potential impact of a security breach, isolate critical systems from the broader network.
Create network segments and use firewalls to contain damage in case one segment is compromised — preserving the integrity of essential systems.
Enhance user authentication by deploying MFA.
This adds an extra layer of security by combining multiple verification methods, such as:
This minimizes unauthorized access — providing a great defense against identity-related breaches.
Ensure disaster recovery and business continuity by maintaining regular backups of encrypted data.
Securely store these backups, regularly test restoration processes, and align with compliance and security policy to form a solid backup strategy.
Avoid social engineering attacks by educating employees on business network encryption best practices.
Conduct regular training sessions focusing on:
This fosters a security-aware organizational culture and massively promotes security standards.
Cyber threats are always involving — and you should be aware of them!
Establish mechanisms for continuous threat intelligence. That way, you can adapt encryption strategies to address new and evolving challenges effectively.
Enhance security by dividing the network into smaller segments.
Restrict lateral movement in the event of a breach by applying segmentation with properly configured firewalls. This minimizes the potential for unauthorized access, which offers more granular control over your network traffic.
Prevent domain hijacking and DNS-related attacks by protecting DNS traffic.
Use DNS security solutions like DNSSEC to verify the authenticity of DNS responses — reducing the risk of malicious domain resolution.
Maintain a robust security posture by conducting regular penetration testing.
This proactive approach identifies and addresses potential weaknesses to ensure the effectiveness of encryption measures.
Efficiently address security incidents by developing a step-by-step incident response plan.
Include predefined steps for identifying, containing, eradicating, recovering, and learning lessons from security events.
Follow network encryption practices with industry-specific compliance standards.
Regularly audit and validate encryption measures against applicable standards to minimize legal and reputational risks.
Business network encryption is one of the most important elements of successful organizations.
From leveraging strong encryption algorithms to staying on top of security trends, by implementing these practices, you can significantly enhance your security posture
