In our experience, an alarming number of enterprise firewalls are configured to inspect traffic coming in but neglect to keep an eye on the data that’s leaving the network. The fight against encrypted injection attacks is a great example of how cybersecurity training, modern firewall solutions, and strong antivirus protections work together hand in hand.Ī firewall’s job isn’t just to inspect incoming traffic, it’s there to make sure nothing unexpected leaves the network too.

Modern DPI-enabled firewalls stand a much better chance of dealing with encrypted threats, but as yet unidentified (“ zero-day”) threats can still slip through the net. Older software systems are less well equipped to adequately inspect and filter encrypted traffic. The phishing link may also ask the user for login credentials (or other sensitive information) as well as delivering its encrypted payload for a cybercrime double-whammy. The email will trick the user into clicking a certain link that injects encrypted code onto the machine – this can be regular malware, fileless malware, or some kind of data access backdoor. Put simply, a firewall with DPI will inspect all of the data packets entering and leaving your network to check for malicious code, malware, and other network security threats.Įncrypted injection attacks are usually delivered via phishing emails. This kind of exploit is particularly dangerous for companies with older firewalls or those that don’t use a feature called “deep packet inspection” or DPI.
