Install macOS a Second Time

You can easily (and safely) install macOS multiple times on the same system because Apple now uses the APFS filesystem, which supports multiple logical volumes on the same underlying partition.

Modern Macs come with a small ARM processor (called the T2 chip) that acts as the SSD storage controller, sound controller, touch bar controller, Trusted Platform Module (TPM) and more.

When you get a new Mac, the filesystem on the SSD is encrypted by default, and this encryption is performed entirely by the T2 chip. While this is generally a good thing for personal files, it causes havoc if you perform many small writes to the filesystem because the multipurpose T2 chip just can’t handle the load like other dedicated storage controllers can.

One of the common themes from the first weeks of the pandemic was businesses realizing that a remote workforce could get the job done (assuming they had the proper tools for working). As time has passed, the situation has become more complicated. From a technical perspective, there are few hurdles in the way of most employees getting their work done. But working in isolation takes a toll, and collaborating over video calls isn’t the same as collaborating in person. There is certainly a cultural element to this, as managers need to be even more in tune with the preferences and mental well-being of their employees. Then the technology has to support the culture of the organization while also evolving to address the needs of a mostly remote workforce.

This technology trajectory is happening today, and the businesses that capitalize on these trends will be more prepared for whatever the future may hold.

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. Our SmartWall®  DDoS mitigation solutions  protect on-premise, cloud, virtual and hybrid environments.   Moreover, cloud-based DDoS defenses a
