Community Picks·2yPostgreSQL databases under attack
Poorly protected PostgreSQL databases on Linux are being targeted by cryptojacking attackers. Aqua Security researchers observed attackers brute-forcing access credentials, creating new high-privilege user roles, removing superuser privileges from compromised roles, and downloading payloads that eliminate competing cryptomining malware. PostgreSQL databases, often found in cloud and on-premises environments, are frequent targets due to lax security or misconfigurations. To protect these databases, using firewalls, VPNs, SSH tunnels, strong passwords, audit logs, and intrusion detection systems is advised.
Cerbos·2y3 Most Common Authorization Designs for SaaS Products
Authorization is essential for securing SaaS applications, ensuring only authorized users access specific resources. This post details three common authorization models: Access Control List (ACL), Role-Based Access Control (RBAC), and Attribute-Based Access Control (ABAC). ACL is simple and quick but may require manual updates as the system scales. RBAC is more scalable, using roles to grant permissions, but can suffer from 'role explosion' as granular control increases. ABAC is the most complex and powerful, using contextual information and attributes to manage access dynamically. Organizations with complex needs might consider third-party solutions like Cerbos for easier implementation.
