Prevention is the best strategy for dealing with cybersecurity threats. Ransomware, DDoS attacks, and malware can damage your network in a matter of seconds, so the best policy is to protect against these issues.
However, hackers find new methods and vulnerabilities to exploit, so you also need to be prepared to respond to security breaches and cyberattacks. Here are three steps to stop network threats and avoid damage.
Monitoring Network Traffic
Network monitoring helps ensure a network is functioning correctly. IT professionals can look at uptime, connected devices, speed, performance, and other information in real-time. These network assessments can also help you quickly spot suspicious, unexpected, or unnatural activity, which could signal a security threat.
Network security experts monitor specific types of network data. Network telemetry, which collects information from different areas and organizes it for easy analysis, can help you locate changes to devices on the system. Look at traffic patterns within the network. A breach could cause unexpected amounts of unexpected traffic. You can also monitor protocols and look at communications between devices, the router, and servers.
The rise in ransomware attacks makes data backups extremely important. If you have the information backed up elsewhere, the ransom may not be necessary.
In other cases where there is a security breach, you can shut down, remove, or block off the compromised portion of the network and rely on backups to continue normal operations.
Block Access to Untrusted Sites
Cybersecurity policies, training, and best practices can help everyone in your company remain secure when using the network. However, be sure that someone doesn’t inadvertently or knowingly visit a dangerous site. You can block access to untrusted sites throughout the system by blocking them via network settings. You can also block access on modems and routers so that people cannot use personal devices to access unsafe URLs.
