If you’re running workloads in Oracle Cloud Infrastructure (OCI) then it’s likely you’ll be familiar with Virtual Cloud Network (VCN) resources such as Subnets, Route Tables, Gateways etc. These software defined components allow you to build networks in OCI for you to deploy and run your workloads.
When it comes to implementing network access controls, you can use Security Lists, Network Security Groups or both. They are virtual firewall features that control traffic at the packet level. I’ll be covering Network Security Group reviews in a later post as I want to focus on Security Lists, specifically how you can easily review and validate rules to ensure they align with your workload, organisational, security and compliance requirements.
If you’re like me, then working in IT means you also assume Tech Support duties for friends, family, and those distant relatives that only seem to call when they’ve got a problem.
I just clicked on this link, and my computer is doing something weird. I think my PC has a virus, what do I do?
When it’s just a single computer, the answer is simple, contain and validate the rouge software is removed, install an AV solution, change their passwords, enable MFA, and provide some education on what to look out for next time.
But now imagine you’re an organisation building a new application, or are moving applications to the cloud. Are you simply performing a lift-and-shift or are you planning to make use of cloud native services? Where are you going to store your data, specifically user uploaded files? Object Storage was built specifically to solve the challenges of how to store unstructured data in the cloud.
However, there is a catch. If you were previously storing files on a server file system, then it’s likely you were also running an anti-virus / anti-malware solution to identify malicious files. With Object Storage the underlying file system is transparent, so you can’t install AV, yet many compliance requirements still state “Uploaded files must be scanned for viruses and malware”.
