There is a fine line between security and stability. So, how do you keep your IT assets running while maintaining a stringent security posture?
Last week, I attended the NotSoSecure Advanced Web Hacking training. While there were plenty of interesting topics taught, one that caught my attention was Out-of-Band (OOB) Data Exfiltration using DNS. Back in 2018, NotSoSecure published an Out of Band Exploitation (OOB) CheatSheet. In that document, they cover methods by which you can exfiltrate data. One of these uses files written to disk and multiple DNS queries to send large chunks of data.
Interest in digital twin technology is on the rise, likely driven by the pressure placed on IT teams to ensure that their networks are predictable, agile, and secure. Network and security operations teams are actively investigating how implementing a digital twin can help their teams become more proactive and provide confidence that the network will behave as expected, even in the face of constant change.
The digital world is a vulnerable space prone to attacks of various kinds. Denial of Service is one of the regular strategy attacks used to crash any server. A DoS attack attempts to make a computer or network resource unavailable to its intended users by generating enormous traffic and costing the legitimate users valuable time and money.
