Oracle recently introduced a Web Application Firewall (WAF) service to further enhance and secure its Oracle Cloud Infrastructure offerings. The Oracle Cloud Infrastructure WAF is based on Oracle Zenedge and Oracle Dyn technologies. It inspects all traffic destined to your web application origin and identifies and blocks all malicious traffic. WAF offers the following tools, which can be used on any website, regardless of where it is being hosted: Origin management. Bot...

There are times when we need to encapsulate certain traffic flows in an overlay network. Hopefully it's a rare need, as it adds additional header overhead, processing requirements and complexity to an environment. Drawbacks aside, the ability to create overlay networks is a valuable necessity sometimes and is a good tool to have in your tool belt! Generic Routing Encapsulation (GRE) is a common tunneling protocol, allowing for encapsulating both IP and non-IP protocols...

OCI provides a load balancing service which can be leveraged to distribute incoming traffic from clients amongst a set of servers. A simple example can illustrate this feature. I have two compute instances in OCI running Apache HTTP Server. The Apaches are listening on port 80 for incoming requests. I have defined a Load Balancer in OCI which routes traffic to these two Backend servers. The Load Balancer accepts http requests over port 80 as shown in the figure above. From...

table td { border-width: 1px; border-color: black; border-style: solid; border-spacing: 1px 1px; padding: 10px; background-color: white; } .cb11w1 ul li, .cb11w1 ol li { line-height: 1.4em; color: #404040 } Identity is the new perimeter. Sounds familiar? In a traditional on-prem world, all the workload had one thing in common. They were all part of a large private network. You could shield that common attack vector (network) with strong security policies using both Web...

NOTE: This article describes a legacy (deprecated) way of solving a problem. The best way to solve it today is through the use of OCI Private DNS! See https://blogs.oracle.com/cloud-infrastructure/announcing-oracle-cloud-infrastructure-private-dns and/or the OCI documentation for more info. It's a common scenario to have DNS name resolution between FQDNs in OCI and your on-prem... or between multiple OCI VCNs. How do we make this happen today? By using a hybrid DNS...

Recently a colleague of mine (Kumar) and myself were facing a scenario where we needed to provide a solution providing disaster recovery (DR) functionality between two OCI regions. It is a fairly common requirement to support some sort of disaster recovery (DR) between different geographical locations. It has been a common practice in traditional enterprise data centers for years and has not changed with the adoption of cloud technologies. Indeed, as cloud consumption has...

OCI offers a very robust and high-performance network firewall that's integrated into the very core of the Virtual Cloud Network (VCN). For some customers, this is sufficient, while other customers need more from their cloud security than is provided natively with the OCI VCN. Some environments need application-level inspection (such as URL filtering, malware inspection, etc.) while others just need the ability to view traffic flows for traffic traversing their cloud...
