AWS Networking – Part VIII: AWS Network ACL (NACL)
In this section, I am going to introduce the default Network ACL for subnets in VPC NVKT-VPC-01.
Figure 1-28 shows the complete structure of our VPC NVKT-VPC-01. We have a Public subnet 10.10.0.0/24 in AZ eu-west-2c a Private subnet 10.10.1.0/24 in AZ eu-west-2a. Both subnets are protected by the default VPC’s NACL named NWKT-NACL. NACL allows all traffic to and from the subnet by default.

In this post, we create a Subnet with the set of properties and attach it to VPC. We also specify a Route Table, which we associate with the Subnet using association.
1) AWS::EC2::VPC (NwktVPC)
2) AWS::EC2::Subnet (NwktSubnet)
3) AWS::EC2::RouteTable (NwktPUB2RouteTable)
4) AWS::EC2::SubnetRouteTableAssociation(NwktRouteTableAssociation)
We are using a Ref function for defining the dependencies between AWS resources when the actual AWS resource Identifier is unknown. For example, the Ref function in AWS::EC2::Subnet resource [2] refers to the resource AWS::EC2::VPC’s logical name NwktVPC (A). We have to use an intrinsic function because we don’t know which VPC Identifier AWS generates to VPC. After creating the subnet, we specify the subnet-specific Route Table [3]. First, we need to bind it to VPC using the Ref function value NwktVPC (B). Next, we “glue” the Route Table to Subnet using RouteTableAssociation, where we use two Ref functions. The first one refers to Route Table (C), and the second to Subnet (D).

Worth Reading: Breaking Down Silos
Here’s another masterpiece by Charity Majors: Why I hate the phrase “breaking down silos”. A teaser in case you can’t decide whether to click the link:
When someone says they are “breaking down silos”, whether in an interview, a panel, or casual conversation, it tells me jack shit about what they actually did.
Enjoy ;)

Contributors: Jason Zhang (NSBU TAU), Stefano Ortolani (NSBU TAU)
Introduction
Formerly known as the Malware Information Sharing Platform, MISP is a leading open-source threat intelligence platform (TIP) that organizations of all sizes can leverage to store, share, and enrich threat indicators of compromise (IoCs).
The MISP ecosystem primarily comprises two parts: MISP core (or engine) and MISP modules. MISP core is responsible for the main functionality of the platform, while MISP modules were introduced to extend the capability of MISP without changing MISP core components.
Thanks to the simple API interface provided by MISP, many third-party MISP modules have been developed to greatly extend MISP’s capabilities. There are mainly three types of MISP modules: expansion modules, import modules, and export modules. More details on MISP modules can be found on MISP’s GitHub MISP module repository, which includes three modules developed by Lastline (now part of VMware) that integrate MISP with VMware NSX Advanced Threat Analyzer (ATA), as we reported earlier.
Recently VMware’s Threat Analysis Unit (TAU) developed a new expansion module, which replaces the three Lastline modules. The improvements from the new module are twofold: a simplified enrichment process and an augmented enrichment capability.

Over the course of this summer, I had the incredible opportunity to join the Workers Developer Productivity team and help improve the developer experience of Workers. Today, I’ll talk about my project to implement the OAuth 2.0 login protocol for Wrangler, the Workers command line interface (CLI).
Wrangler needs to be authorized in order to carry out its job. API tokens are one way to authorize Wrangler, but they do not provide the best user experience as the user needs to manually copy and paste their tokens. This is where the OAuth 2.0 protocol comes into play.
Wrangler login and OAuth 2.0
Previously, the wrangler login command used API tokens to authenticate Wrangler. However, managing API tokens can sometimes be cumbersome, since you need to go to the Cloudflare dashboard to create or modify a token. By using OAuth 2.0, we can allow users to directly choose permissions or scopes from Wrangler. OAuth 2.0 helps simplify the login process while making it more secure.
OAuth 2.0 is an industry-standard protocol for allowing users to authorize applications without having to share a password. In order to understand this protocol, we need to define some Continue reading
What Are Mesh Routers For Wi-Fi
There may be many reasons as to why the Wi-Fi at your house does not work. Weakened Wi-Fi signals could be a result of any physical obstruction or it can also be caused by dead spots. This is the reason as to why the Wi-Fi at your home does not work well. But what can we do to fix this problem? Is this even a problem? Yes definitely it is a problem. Weakened Wi-Fi means nothing but slow internet connectivity which means that you might not be able to join your online class on time, might miss the meeting, might not be able to send in the email to your boss or simply just experience a pause at life. In the rowing times people almost across the globe are highly dependent on Wi-Fi and internet connectivity. Having a slow internet can defiantly become a headache for many of us. The solution can be simple: a mesh router for Wi-Fi or full home Wi-Fi is the most ideal solution
