Comparison of Gantt chart and Critical Path methodology

Gantt charts do not show how activities relate to one another, but Critical Path methodology shows how each activity is related to one another
Gantt chart is in the form of a bar chart that lays out project activities and timelines for each activity. The critical path method represents a network diagram that displays each project activity and connects them to show task dependencies

The CPM and Gantt chart are essential concepts for the CISA exam. The CISA certification is a globally recognized certification developed to validate candidates’ skills to manage, monitor, and protect the organization’s IT business environment. The CISA certification training course aims to provide candidates with hands-on knowledge to detect vulnerabilities, report compliance issues, and deploy IT security control.
Critical Path Analysis is commonly used with all forms of projects, including construction, aerospace and defense, software development, research projects, product development, engineering, and plant maintenance.
Any project with interdependent activities can apply this method of mathematical analysis.
All project schedules have (at least) one critical path, usually only one in non-manipulated project schedules.
The critical path is important because if everything goes according to the schedule, their duration gives the shortest possible completion time for the overall project
Activities that are not in the critical path have slack time
Slack time – It is defined as the amount of time a task can be delayed without causing another task to be delayed or impacting the completion date of the overall project.

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
