Firewall technology for network security has undergone considerable advancement with the introduction of cloud computing and the vanishing network perimeter with hybrid and multi-cloud environments. All along this transformation one thing that did not change is the way endpoints are identified – through the TCP/IP stack, specifically the IP address. This design principle needed a change for container-based applications. How did the NGFWs fare?
This is how Maya, a devSecOps team lead at one of the prominent software development companies, started her presentation in front of Security leaders to show how the Agentless vulnerability management approach helped her: In this blog post, we’ll introduce you to Sysdig’s new Agentless scanning for vulnerability management.
While the cloud serves as a powerful accelerator for businesses, it also speeds up threat actors. Automation and an ever-increasing level of sophistication allow threat actors to execute complex attack chains in merely minutes, sometimes even less.The risk factors are amplified by the ability to chain together exploits and quickly move laterally in cloud environments, where a single breach could lead to a business critical compromise.
In the modern software ecosystem, containerization has become a popular method for packaging and deploying applications. Alongside this growing trend, ensuring the security of software supply chains has become a critical concern for businesses of all sizes. Implementing best practices, such as signing and verifying images to mitigate man-in-the-middle (MITM) attacks and validating their authenticity and freshness, play a pivotal role in safeguarding the integrity of the software supply chain.
This is a follow up discussion of some advanced use case scenarios for Egress Gateways. In a previous blog post, Policy-based routing with Egress Gateways, I explained how to achieve connectivity to multiple destinations using policies based on the destination of the traffic. One of the use cases described was the ability of connecting to different services based on the destination, so we can use a different source IP that can be included in an allowlist for such services.
According to CSO the fines incurred for data breaches or non-compliance with security and privacy laws, for only a handful of companies, has cost $4.4 billion. The global average cost of a data breach in 2023 was $4.45 million, a 15% increase over 3 years (IBM). The challenge for organizations is how to safeguard sensitive information while adhering to the law, but without compromising innovation. Cyber threats loom large, affecting businesses in every industry.
By default, traffic leaving a Kubernetes cluster lacks a meaningful network identity, making it challenging to associate it with its source workload. This is an issue because, in an on-premises infrastructure, companies rely on firewalls, for example Sophos Firewall, to inspect this traffic which loses its identity as soon as it leaves the cluster.
