Using Git to Collaborate

While we just saw how Git can perform version control for your local files and how other users can download (or clone) copies of your Git repos on the same computer or across a network (LAN or Internet). Those users can then create commits periodically after making changes to the files in their cloned repo and push those changes back to your original repo.

Any computer running Git can clone a Git repo from any other computer running Git, regardless of the operating system used. There are many free sites you can use to host Git repos online, including GitHub and GitLab.

Let’s experiment with this using another user (root) on the same computer – the only requirement is that the other user has read/write access to your repo folder.

The following commands run by the root user (the other user) create a cloned copy of the myscripts repo (/home/jason.eckert/myscripts) within the root user’s home directory (/root) using the git clone command:

Look back at the output of the git status command from earlier, and you will notice it names you as the “On branch master.” A branch is simply a section of your Git repo, much like the different partitions on a hard disk.

Any changes you make to an original or cloned Git repo are part of the master branch by default. But you can create as many other branches as you like to store changes that you may want to experiment with. Once you are satisfied that the changes work as you expected, you can merge the changes you made in your branch with the files in the master branch.

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.
