Cyberattacks in business communication

Business communication relies heavily on technologies such as VoIP telephone systems, email, CRM platforms, and collaboration tools. While these technologies enhance productivity and reduce costs, they also attract cyberattacks. In this article, we will analyze the main threats, how to identify them, and the preventive measures you should take to protect your company's communication.

Main threats in business communication

Cyberattacks on businesses aim to steal data, disrupt operations, or gain financial benefits. Some of the most common threats include:

• Phishing emails: Messages that appear legitimate but attempt to extract sensitive information.

• Denial of Service (DoS): Attacks that disrupt services by overwhelming the network.

• Malware: Malicious software that can access data or monitor communications.

• VoIP fraud: Scams targeting VoIP phone systems, such as unauthorized calls and call interceptions.

Understanding these threats is the first step toward developing appropriate protection strategies.

How to identify cyberattacks

Early detection of a cyberattack can prevent severe consequences for your business. One of the first warning signs is increased network traffic, which is often linked to DoS attacks or malware activity.

Additionally, unusual activity, such as unexplained charges on phone bills or suspicious system logins, may indicate a potential security breach. Moreover, unauthorized changes to files or system settings can be a clear sign of a cyberattack.

Finally, poor VoIP call quality, including frequent disruptions or delays, may result from malicious interference.

To ensure business protection, implementing a monitoring and activity analysis system is essential. This enables the timely detection and management of suspicious activities.

Preventive measures and best practices

Prevention is the best defense against cyberattacks. The following measures can help protect business communications:

1. Employee training: Cybercriminals often target employees through phishing. Train staff to recognize suspicious emails and links

2. Encryption usage: Secure VoIP communications and data with strong encryption (e.g., SRTP or TLS) to prevent eavesdropping.

3. Access control restrictions: Implement access levels so only authorized users can access sensitive data.

4. Software and hardware updates: Updates fix security vulnerabilities exploited by hackers. Keep all systems and devices up to date.

5. VPN implementation: A Virtual Private Network (VPN) protects communications over public networks.

6. Strong password policies: Passwords should be complex, unique, and changed regularly.

7. Continuous monitoring and reporting: Install monitoring systems to detect anomalies and analyze network activities.

The best security strategy is one that identifies and resolves issues before they become critical. If you experience frequent disruptions or suspicious activities, consider outsourcing monitoring and security management to experts. Additionally, regular penetration tests can help identify vulnerabilities before cybercriminals exploit them.
