THE FIREWALL IS OUT OF ORDER: WHAT TO DO?

Even the best configured rules will not help if the firewall is out of order. Such shutdown can last from several minutes to several hours. It is necessary to prepare for such situations in advance: you need not only to have a replacement device, but also to make sure that the replacement turns on automatically in the event of a failure. Thus, you can have one firewall configured and active, while the other is in standby mode. It will be enough to connect both devices with a failover cable and configure them so that both firewalls send messages at a specified interval, for example, every few seconds. List further communication attempts in case the communication request remains unconfirmed network security firewall.

If the device does not respond to further communication attempts, the system can assume that the firewall has failed and activate the backup device. It is also desirable to connect the firewall to the monitoring module. This will ensure that the packets that the firewall should block are being blocked. You should also integrate a mechanism for reporting problems and errors.

CONCLUSION

Firewalls are essential to protect your online store from manipulation, unauthorized access, and espionage. Thanks to the ability to distribute access rights, the firewall protects against unauthorized access both from inside the network and from outside. Unwanted traffic is blocked, so the firewall also protects your system from malware. In conclusion, we can say that ideally a firewall performs the following functions:

controls access to the Internet and the network,

protects traffic for incoming and outgoing connections,

actively monitors the operation of applications,

ensures confidentiality,

notifies about events that deviate from the norm and therefore may be suspicious.

Without a doubt, a firewall belongs to the main protection tools, but its mere presence cannot guarantee complete security. The firewall settings should be tailored to your needs based on your threats, risks and IT infrastructure. You should also constantly check the operation of the firewall and document all actions so that the firewall protects your online store as effectively as possible.
