Network sandboxes: advanced shield against cyber threats

A primary protection tool in the cybersecurity landscape is represented by the network-based sandbox. This technology, which has shown remarkable maturity, is effective for detecting, disrupting and investigating incidents related to Advanced Persistent Threats (APT). The sandbox allows a constant and timely analysis of suspicious files. It also has the ability to feed collected data into security information management platforms such as Security Information and Event Management (SIEM) and Extended Detection and Response (XDR). The heart of this system lies in its ability to dynamically analyze suspicious files within an isolated environment, producing a detailed report ready for further examination or to be sent to advanced security tools for further processing.

Technical features and sandbox implementation

The sandbox is an isolated digital territory used for the analysis of potentially harmful objects, such as suspicious email attachments. It collects as much data as possible from sensors scattered throughout the network, which can include devices or applications of various types. Static analysis doesn't always detect malicious code, so the sandbox allows you to dynamically examine the behavior of a sample. This tool is effective against all types of malicious code, from backdoors and trojans to banking malware and ransomware. Its fields of application are vast: computers, mobile devices, applications, operating systems and much more.

Detection of threats and evasion strategies used by criminals

The sandbox proves extremely effective in detecting malware, vulnerabilities in a corporate DNS server or flaws in Google Play libraries that allow mobile apps to escalate their privileges, thus making it easier for attackers to mask their tracks. Additionally, the sandbox is able to detect backdoors in process memory, where behavioral analysis usually fails. However, attackers are always looking for new ways to circumvent the sandboxes, whether it's looking for signs of a hypervisor, analyzing document and browser history, or examining processor characteristics.

Sandbox market: future predictions and conclusions

In the future, sandboxes will become smarter and easier to use, enhancing their protection capabilities with the use of machine learning modules. The global sandbox market is growing rapidly and is expected to double in the next couple of years. Cloud-based solutions, delivered as a sandbox-as-a-service, represent one of the main evolutionary vectors for this technology. In addition, the ever-tighter integration with DDP platforms and the strengthening of machine learning modules are important trends. Despite growing automation, the intervention of an information security expert remains essential for effective management of the sandbox.
