This Cyber Security Awareness month, we’re thrilled to launch The 403 Circle, our new community-driven approach to building a safer world. It isn’t for everyone, but it might be for you. We are surrounded by an overwhelming trove of information, from AI chatbots and mile-long whitepapers to social networks or ‘communities’ that treat you like a product—to acquire, upsell, and renew contracts. At Astra, we strive to simplify proactive security.

In the realm of network security, safeguarding communication ports is a fundamental aspect of protecting a network’s integrity and confidentiality. Port 139, primarily used by the Server Message Block (SMB) protocol for file sharing in Windows networks, stands out as a critical point of vulnerability when not properly secured. This port facilitates network communications, allowing computers to share files, printers, and serial ports over a network.

As the official implementation date approaches for the Digital Operational Resilience Act (DORA) – financial institutions and their information and communication technology (ICT) service providers, across the European Union are gearing up for a significant shift in their operational landscape.

Product security leaders face the monumental task of identifying and safeguarding their most critical cloud and application assets within large and complex cloud environments.

In the intricate matrix of network communications, TCP port 445 stands as a crucial node, facilitating the swift and efficient exchange of resources like files and printer services between computers on the same network. Yet, its significance as a channel for Server Message Block (SMB) communication within Windows operating systems also marks it as a vulnerable target for cyber threats.

Runtime security in multi-cloud environments encompasses the continuous monitoring and protection of cloud-based resources during their active operation. Unlike traditional security approaches that focus on static configurations or pre-deployment checks, runtime security emphasizes: This approach ensures that potential risks are identified and mitigated in real-time, providing an additional layer of protection against both known and emerging threats in complex multi-cloud setups.

Due to their numerous components and dependencies, web applications often have multiple vulnerabilities—many of them unknown and susceptible to zero-day attacks—that can be exploited by malicious HTTP requests. Determining whether a vulnerability exists is challenging without visibility into an application’s real-time data and event flows, which isn’t possible with existing firewall-based solutions.
