ABAC extends RBAC by introducing attributes as the basis for access control decisions, allowing more dynamic and granular access management. Instead of relying solely on predefined roles, ABAC uses the attributes of users, resources, and the environment to determine access rights. Key Components 1. Attributes: - User Attributes: e.g., Department, Job Title, Clearance Level. - Resource Attributes: e.g., File Type, Data Sensitivity. - Environmental Attributes: e.g., Time of Access, Device Used, Location.
2. Policies: Define rules based on attributes, often written in formats like JSON or XML.
Example Policy | Condition | Access Allowed | |-------------------------------------------|----------------------------| | Department = "HR" AND File Type = "PDF" | View or Download Only | | Clearance Level = "High" AND Time = "9:00 AM - 6:00 PM" | Read, Write, Delete |
💡Benefits: - Flexibility: Adapts to complex requirements. - Granularity: Offers fine-tuned control over resources. - Dynamic Security: Responds to real-time conditions like location or device type.
💡Use Case: ABAC is ideal for systems that require context-sensitive decisions, such as granting access to sensitive financial data only during business hours or limiting operations based on device security.

The Singapore stock market has alternated between positive and negative finishes through the last five trading days since the end of the two-day winning streak in which it had added more than a dozen points or 0.4 percent. The Straits Times Index now sits just above the 3,060-point plateau and it's likely to see a narrow trading range on Monday.
Telegram and Signal Havens for Right-Wing Extremists
Since the violent storming of Capitol Hill and subsequent ban of former U.S. President Donald Trump from Facebook and Twitter, the removal of Parler from Amazon’s servers, and the de-platforming of incendiary right-wing content, messaging services Telegram and Signal have seen a deluge of new users. In January alone, Telegram reported 90 million new accounts. Its founder, Pavel Durov, described this as “the largest digital migration in human history.” Signal reportedly doubled its user base to 40 million people and became the most downloaded app in 70 countries. The two services rely on encryption to protect the privacy of user communication, which has made them popular with protesters seeking to conceal their identities against repressive governments in places like Belarus, Hong Kong, and Iran. But the same encryption technology has also made them a favored communication tool for criminals and terrorist groups, including al Qaeda and the Islamic State.
