Private Hosted Zone in AWS Route53 allows to limit access to DNS records of a domain, thus making it inaccessible for the DNS Enumeration (or DNS brute-force), when an attacker checks for available records in a domain to know endpoints list to check them for vulnerabilities. For such attacks, there is a lot of utilities… Read More »
In the first post – AWS: Web Application Firewall overview, configuration, and its monitoring – we spoke about its main components, created a WebACL and Rules for it, and did basic monitoring. Also, we’ve configured WebACL’s logs collection with AWS Kinesis, but now it’s time to see them Logz.io, as CloudWatch Logs isn’t available for… Read More »
AWS WAF (Web Application Firewall) is an AWS service for monitoring incoming traffic to secure a web application for suspicious activity like SQL injections. Can be attached to an AWS Application LoadBalancer, AWS CloudFront distribution, Amazon API Gateway, and AWS AppSync GraphQL API. In case of finding any request that sits WAF’s rules, it… Read More »
In the previous post ArgoCD: users, access, and RBAC we’ve checked how to manage users and their permissions in ArgoCD, now let’s add an SSO authentification. The idea is that we don’t add user accounts locally in the ArgoCD’s ConfigMap, but instead will use our Okta users databases and Okta will perform their authentication. And… Read More »
ArgoCD has two types of users – local, that are set in the argocd-cm ConfigMap, and SSO. Below, we will speak about local user management, and in the next chapter will see how to integrate ArgoCD and Okta, because local users can’t be grouped in groups. See the documentation on the Local users/accounts page. For… Read More »
For the authentification and authorization, Kubernetes has such notions as User Accounts and Service Accounts. User Accounts – common user profiles used to access a cluster from the outside, while Service Accounts are used to grant access from inside of the cluster. ServiceAccounts are intended to provide an identity for a Kubernetes Pod to… Read More »
So, as a follow-up to the Helm: Kubernetes package manager – an overview, getting started post – let’s discuss about sensitive data in our Helm charts. What I want is to store a chart files in a repository, but even if such a repo will be a private Github repo – I still don’t want… Read More »
The next task is to add a new user who will have access to check pods state and watch logs – any other operations must be prohibited. AWS EKS uses AWS IAM for authentification in a Kubernetes cluster (check the Kubernetes: part 4 – AWS EKS authentification, aws-iam-authenticator and AWS IAM post for details), bot… Read More »
Currently, I’m using KeePass as passwords, RSA-keys, and as the Freedesktop SecretService, see the KeePass: an MFA TOTP codes, a browser’s passwords, SSH keys passwords storage configuration and Secret Service integration post. The first issue I faced with during such a setup is the fact that KeePass’ database is synced between my computers (it’s database… Read More »
When using an MFA for an email account you can face an issue when the same mail account may be used by multiple team members and each of them needs to have the MFA configured. for example, we have a mailbox company-admin@google.com and I’d like to set up an MFA protection on it with Google… Read More »
