Database-level Roles

Database roles work the same as server roles, except that they allow you to assign database-level permissions instead of server-level permissions.

To create a database role, use the same procedure detailed above for server roles. For example, you might use the following commands:CREATE ROLE dbrole GRANT SELECT ON DATABASE::TestDatabase TO dbrole ALTER ROLE dbrole ADD MEMBER exampleuser2

Securables

Principals receive permissions to securables. Securables are the resources for which access is regulated. Securables can have nested hierarchies, called “scopes,” which also can be secured. The securable scopes are server, database and schema. (A database schema is a skeletal structure that represents a logical view of an entire database. It defines how data is organized and how the relationships between them are related. It spells out all the constraints that must be applied to the data.)

DDoS Attack Mean for My Security?

You need to prepare and plan to manage a DDoS attack against your systems. You need to monitor, generate alerts, and quickly diagnose a DDoS attack in progress. The next step is shutting down the attack quickly without affecting your users. You can block the IP addresses using your Next-Gen Firewall, or close inbound traffic to the targeted system and failover to a backup. There are other response plans you can implement, make sure to have one. Some CDNs, like Cloudflare, also act as a reverse proxy which can further protect your WordPress site from DDoS attacks. An HTTP Flood attack, for example, is an application layer attack that targets a web server on the target and uses many fast HTTP requests to bring the server down. Think of it as pressing the refresh button in rapid-fire mode on your game controller. That kind of traffic from many thousands of computers at once will quickly drown the webserver. Who should consider using a CDN: Most websites can benefit from integrating a CDN

Profiling Hackers in the MITRE ATT&CK Navigator

Using the MITRE ATT&CK Navigator or similar tools, organizations can categorize attacks by specific threat groups and threat actors. It is even possible to profile the technologies and the procedures attackers use. In short, you will have a strong idea of the next move your opponents are going to make. Notice that each of the technologies is categorized into a version of the hacker lifecycle. The top of the page reads Initial access, Execution, Persistence, Privilege Escalation and so forth. These are the general steps that attackers take as they compromise a network. The MITRE ATT&CK Navigator then allows you to profile specific attack groups. Each group profiles an actual group of cyberattackers. Using this model, you can quickly identify how each group operates. Going back to my baseball analogy, imagine if you knew that a group of pitchers behaved a certain way. Now, you can profile that behavior and train your batters to best address how those pitchers are trying to defea

The Importance of Post-Attack Analysis

Comprehensive visibility into an organization’s network activity is essential not only to quickly combat DDoS threats, but also to enable compliance reporting and archive security event data that enables security audits and forensic analysis of past threats. Organizations can learn from past attacks to uncover hidden patterns of data and identify emerging vulnerabilities within the massive streams of security event data Without this level of visibility, it is impossible to determine how effectively an attack was mitigated and whether there were any false-positives which led to collateral damage that substantiates any service level agreement (SLA) claims. For over a decade, Corero has been providing state-of-the-art, highly-effective, automatic DDoS protection solutions for enterprise, hosting and service provider customers around the world.
