Replicate Proximity Placement Group workloads in Azure

Chiyo OdikaAZURELeave a Comment

Azure Site Recovery (ASR) now supports proximity placement groups (PPGs) from the Azure portal. Recall that previously, ASR only supported Proximity placement groups when configured via PowerShell. The new functionality in the portal is a lot more seamless, and I highly recommend it for replicating for failover and failback to a secondary region, any workloads that are configured within proximity placement groups. Recall that proximity placement groups is a construct that enables you to logically group your application components together to avoid network latency between the various tiers of your application. The use case for this in the context of site recovery is that while PPGs provide optimal network latency for your application, you also want to ensure that in … Read More

Addressing Critical ZeroLogon Vulnerability CVE-2020-1472

Chiyo OdikaAZURE, SecurityLeave a Comment

The ZeroLogon vulnerability is a privilege elevation vulnerability that exists when an attacker establishes a vulnerable NetLogon secure channel connection to a Microsoft Windows Server Domain Controller, allowing the attacker to perform a NetLogon authentication bypass attack, which simply put, can enable an attacker to obtain domain admin access, and take over an organization’s domain and effectively disrupt the organization’s functionality through ransomeware payload installation, for instance. This Zero-day vulnerability was discovered by Security firm, Secura, and Microsoft has recently confirmed that this vulnerability is actively being exploited in the wild. Secura has released a PoC code on their Github, that actually allows exploitation of this vulnerability and it’s use and deployment is quite intuitive. If the increasing discoveries of … Read More

What retail investors can learn from Warren Buffet’s Investment strategy

Chiyo OdikaUncategorizedLeave a Comment

Last week, Warren Buffet’s Berkshire Hathaway (NYSE: BRK.A) (NYSE: BRK.B) made a sizable purchase to increase its stake in Delta Air Lines (NYSE: DAL)on a major down day and amidst unnerving turbulence in the markets. Last week will linger on in memory for a while as the harbinger of what is now undoubtedly the markets’ slide into bear-market territory, probably precipitated by the oil price collapse, triggered over the weekend by the OPEC-Russia impasse, and fueled on by the inexorable spread of COVID-19. We saw several alternating days in a row of big moves in the S&P 500 of plus or minus 4% or more, and we saw even bigger moves this week with the circuit breaker triggered after the … Read More

NSGs for Azure APIM with VNET

Chiyo OdikaAZURELeave a Comment

I’m doing some work on deploying Azure API Management inside a VNET in order to access backend services and had to enumerate a list of Network Security Group (NSG) rules to allow inbound and outbound traffic into the subnet in which API Management is deployed. Posting the JSON here so for easy reference. Still testing this out, so let me know if I missed any ports. Cheers! { “$schema”: “”, “contentVersion”: “”, “parameters”: { “nsgname”: { “type”: “String”, “metadata”: { “description”: “NSG Name” } }, “location”: { “type”: “string”, “defaultValue”:”[resourceGroup().location]”, “metadata”: { “description”: “location value for all defined resources” } } }, “variables”: {}, “resources”: [ { “type”: “Microsoft.Network/networkSecurityGroups”, “apiVersion”: “2019-11-01”, “name”: “[parameters(‘nsgname’)]”, “location”: “[parameters(‘location’)]”, “properties”: { “securityRules”: [ { … Read More

This is likely the first non-technology article I’m publishing here, and it is the first of many to come. So indulge me, as I lighten the content in this here blogosphere of mine. What a whirlwind week it’s been indeed. What with the global financial markets in a tailspin, and reeling from a coronavirus-driven rout, and Elton John’s beloved, albeit bottom table-dwelling Watford putting paid to Liverpool’s bid for a record-setting 19 unbeaten games in the top flight of English football. But this article isn’t about the market. There’s another 5 articles coming on that subject. This is purely about the beautiful game, football. Yes,  It’s been 422 days since Liverpool lost a game in the Premier league. And while … Read More

Zero Trust and the Azure Firewall service

Chiyo OdikaAZURELeave a Comment

I’m a proponent of zero trust for enhancing network-level security and access control for your Azure resources. The idea is that of demarcating your high-security deployments from the internet, using a perimeter network, aka DMZ. What this enables you to do is focus your network access control, logging, monitoring, alert/event management workflow integration on your edge devices, not necessarily as a stand-alone solution, but as a part of an overarching solution for access control, and oversight at the network layer. Think NSGs/ASGs (in the Microsoft cloud) as fitting somewhere into this picture, and let’s not overlook Identity and the role it plays as a pillar of security, but that’s a topic for another day. Now with that said, most enterprises … Read More

Making the move to Azure Security Center and Azure Sentinel

Chiyo OdikaAZURELeave a Comment

This article is not intended as a technical deep-dive into the Azure Security Center (ASC) and Sentinel solutions from Microsoft. There are loads of instructive docs on these from Microsoft. I intend for this article to simply serve as a reminder for OMS Security and Compliance clients to make the switch to Azure Security Center and explore the Sentinel SIEM solution which is currently in preview and free. The Security and Compliance solution reaches EOL at the end of July 2019.     Recall this security event log filtering feature that informed SecurityEvent table data in your Log Analytics repo, and that lived somewhere in the erstwhile OMS Security & Audit UI? Well it’s wound up in Azure Security Center. … Read More
