Networks

Network security services like Google Cloud Armor enable you to filter incoming traffic so that you can prevent attacks from overwhelming your system or from reaching critical components of your application. However, these services often handle threats automatically, making it difficult to gain visibility into attempted security breaches.

Cyber security investors, vendors and the press are abuzz with a new concept introduced by Palo Alto Networks (PANW) in their recent earnings announcement and guidance cut: Platformization. PANW rightly wants to address the “point solutions fatigue” experienced by enterprises due to the “point solution for point problem” mentality that has been prevalent in cyber security over the years.

In this second post of our threat hunting with Corelight and CrowdStrike blog series we dive into Persistence, which is one the many tactical categories outlined in the MITRE ATT&CK framework. In our previous blog, we reviewed some of the common techniques in the Initial Access category, like Drive-By Compromise and Spearphishing. In this post, we examine and provide some useful threat hunting tips on some of the common tactics attackers use to maintain long-term access to a target's environment.

Before I became a Sale Engineer I started my career working in operations and I don’t remember the first time I heard the term zero trust but I all I knew is that it was very important and everyone was striving to get to that level of security. Today I’ll get into how AlgoSec can help achieve those goals, but first let’s have a quick recap on what zero trust is in the first place.

The “Network access: Restrict clients allowed to make remote calls to SAM” security policy setting manages which users are permitted to view the list of users and groups stored in both the local Security Accounts Manager (SAM) database and Active Directory through remote calls. This policy setting allows you to restrict remote RPC connections to SAM. If not selected, the default security descriptor will be used.

Short for High Availability Proxy, HAProxy is an open source and high-performance HTTP load balancer and proxying solution. It enhances website and application performance by distributing workloads across multiple backend web servers. This results in reduced response times, increased throughput, and high availability. Although HAProxy is free and open source, there is also a commercial option called HAProxy Enterprise.

Every business needs to manage risks. If not, they won’t be around for long. The same is true in cloud computing. As more companies move their resources to the cloud, they must ensure efficient risk management to achieve resilience, availability, and integrity. Yes, moving to the cloud offers more advantages than on-premise environments. But, enterprises must remain meticulous because they have too much to lose.

In my previous blog post, What you can’t do with Kubernetes network policies (unless you use Calico): Advanced policy querying & reachability tooling, I talked about this use case from the list of nine things you cannot implement using basic Kubernetes network policy — advanced policy querying and reachability tooling. In this blog post, we’ll focus on the use case — the ability to log and analyze network security events.
