How to shield communications channels from cyberthreats and find actionable strategies to enhance security

The threat of cyberattacks and ransomware is a growing concern for businesses worldwide. As hackers become more sophisticated and their attacks more frequent, it is essential for companies to prioritize the security of their communications channels.

Financial gain, espionage and disruption are the top motivating factors of cyberattacks. But it is the increasing reliance on digital systems and the valuable data they contain that is behind the rise.

Cyberhackers target organizations to gain access to their digital ecosystem and infiltrate their sensitive processes. Their goal is to exploit vulnerabilities in corporate networks to steal sensitive data such as customer information, intellectual property, financial records, or trade secrets.

Furthermore, cybercriminals can disrupt operations or demand ransoms through ransomware attacks, social engineering, phishing, spoofing and so on. Attacks often come from multiple communications channels and a lack of understanding about securing communications.

Securing BYOD

Ignoring security protocols and using unauthorized, insecure resources heightens the risk of cyberattacks.

For Bring Your Own Device (BYOD) policies, it is important to note that BYOD is acceptable when certain conditions are met. Specifically, devices must be equipped with robust security agents such as EDR/XDR. And the use of these devices must be formally reported to the Chief Information Security Officer (CISO) within your organization. This approach ensures a sufficient level of security and protection for a safer computing environment.

Data breaches and leaks

As remote work continues to gain popularity, so have the risks associated with unsecured Wi-Fi hotspots in public places and home internet connections.

These weaknesses have created numerous access points for potential exploitation. Indeed, the use of corporate PCs can help prevent problems of unsecure connections in public/home environments.

Data breaches and leaks are primarily focused attacks, with an initial phase called “reconnaissance”. This initial step involves gathering information on an organization from public habits or conversations, or other open sources (such as OSINT or social media).

The need for improved data security is primarily due to a lack of employee awareness, and the failure to separate personal and professional work environments. It is also important to exercise caution and not share too much information when using social media.

Best practices for cybersecurity

1. To protect your corporation from cyberthreats, it is crucial to implement and follow practical guidelines that will reinforce your cybersecurity defenses.
2. Do not share passwords on browsers
3. Provide employees with regular cybersecurity training for effective recognition and response
4. Get robust, up-to-date antivirus and anti-malware software on all devices, and keep systems and software patched and updated
5. Use strong, unique passwords and implement multi-factor authentication whenever possible
6. Scrutinize security measures, data encryption protocols and vulnerability management when choosing a solution based on the Cloud
7. Regularly back up essential data and store backups offline to limit ransomware risks
8. Limit access permissions and use the principle of least privilege, ensuring employees have access only to what they need
9. Audit and monitor network activity for unusual behavior and have an incident response plan in place to act swiftly in case of cyberattack
10. Stay informed about evolving cyberthreats and adapt security measures accordingly

Encrypted VoIP calls

It is also essential to protect communications and voice conversations over the internet.

For Voice over Internet Protocol (VoIP) calls, users should be aware that encrypted VoIP calls offer a secure shield against eavesdropping and data interception, ensuring the confidentiality of sensitive conversations. Opt for VoIP service providers that employ end-to-end encryption protocols, and use applications or platforms that prioritize security or encrypted VoIP features. By taking these proactive steps, you can bolster your digital defense and keep your conversations truly private.

Flexibility and VPN, are they compatible?

Organizations usually know the importance of using a Virtual Private Network (VPN) for securing data and communications. It is also essential to consider whether the VPN is flexible enough to accommodate the full spectrum of an organization’s requirements.

VPNs protect remote work data but may not suit all digital infrastructures. It is also important to check if your VPN aligns with your scalability, performance wishes and the varied technology system.

Ensuring data sovereignty and compliance

Reviewing certifications and compliance is crucial for data security and reducing cyberattack risks.

Non-compliance with General Data Protection Regulation (GDPR) and the Health Insurance Portability and Accountability Act (HIPAA) can result in severe penalties. Prioritizing compliance safeguards data and enhances reputation and trustworthiness.

In terms of security and certifications, Rainbow by Alcatel Lucent Enterprise takes several robust measures to ensure the fullest protection of its users’ data. The Rainbow solution is independent of any non-sovereign Act.

By doing this, the platform maintains a high level of data integrity and sovereignty. This ensures all data and exchanges on the platform remain shielded from external interference.

The frequency of cyberattacks in today’s digital landscape highlights the crucial importance of robust cybersecurity measures for corporations. When corporations utilize Cloud solutions, they should carefully consider the security measures implemented in their design. For example, corporations must assess their cloud providers’ compliance, certifications and security to safeguard data from emerging threats.
