Software-defined wide area networking (SD-WAN) is a distributed networking approach that provides organizations a sustainable alternative to high latency hub-and-spoke network topologies.

Wireless networks have become an integral part of how we conduct our businesses. They ease many processes and help us get rid of the clutter caused by hundreds of wires yet keeping wireless networks safe poses some challenges. Wireless technologies offer convenient solutions to our needs. They are practical and fast, moreover they set us free of the clutter caused by wires and cables. On the other hand, it is no secret that wireless networks are more vulnerable to attacks and intruders.

Being one of the most popular tools used in network security, Encapsulating Security Payload (abbreviated as ESP) offers the help we need in keeping the integrity, authenticity and confidentiality of the information we send across networks. Keep reading to learn more! With the technological advancements, the way we conduct our business processes has changed immensely. Now, we heavily rely on the internet technologies and transfer massive amounts of data daily.

IT Services rely on an individual port assigned to them in order to receive and transmit information, therefore, it’s imperative that an organization keeps track of what ports are open within their IT environment, the function of the port and what services it’s associated with. Detecting and disabling unwanted ports is part of an ongoing hardening process.

This Investigation was initiated on the basis of several Network Anomaly alarms triggered by ongoing suspicious activity on an employee device owned by a financial institution. During the discovery phase of the Investigation, we identified abnormal egress traffic to a known Indicator of Compromise (IOC) based on intelligence from the Open Threat Exchange™ (OTX®).

Internet Key Exchange (also known as IKE, IKEv1 or IKEv2) is a protocol that is used to generate a security association within the Internet Protocol Security protocol suite. In this article, we will discuss Internet Key Exchange in detail and explain why it is important for network security.

Creating security policies for the devices connected to your network is critical to ensuring that company data is safe. This is especially true as companies adopt a bring-your-own-device model and allow more personal phones, tablets, and laptops to connect to internal services. These devices, or endpoints, introduce unique vulnerabilities that can expose sensitive data if they are not monitored.

The Server Message Block Protocol (SMB Protocol) is a client-server communication protocol used for sharing access to files, printers, serial ports, and data on a network. It can also carry transaction protocols for authenticated inter-process communication. In short, the SMB protocol is a way for computers to talk to each other. SMB works through a client-server approach, where a client makes specific requests and the server responds accordingly. This is known as a response-request protocol.

Global health events in 2020 have accelerated a trend. Office workers are working from home more frequently. This is great for many reasons. Companies can save money on office space. People are often more productive in the environment they’re most comfortable in, their homes. Rush hour can be mitigated with fewer cars on the road.

New applications and workloads are constantly being added to Kubernetes clusters. Those same apps need to securely communicate with resources outside the cluster behind a firewall or other control point. Firewalls require a consistent IP, but routable IPs are a limited resource that can be quickly depleted if applied to every service.
