Critical path Method

 What is the critical path in project management

  • the critical path is the longest sequence of tasks that must to executed in order to complete the task
  • the tasks on this path are called critical activities, if they are delayed, the entire project completion is delayed
  • non-critical task sequences can be delayed without affecting overall project time, as long as they do not get delayed past the end of the critical path
  • the critical path can be found using a method called CPM or critical path method, however it can now also be automatically calculated by project scheduling software equipped with Gantt charts
  • Finding the critical path allows managers to:
    • Accurately estimate total project duration
    • identify the critical activities, to be able to closely supervise them
    • likewise, find tasks that could be delayed or rescheduled without affecting the total time of the project
    • create realistic schedules
    • identify task dependencies, resource constraints and project risks

Technical and Non-Technical Threats to Organizations

Technical and Non-Technical Threats to Organizations Several threats to organizations are capable of doing large damage. These are either technical or non-technical (environmental, human, and procedural). Technical Threats Botnets: A botnet is a collection of hacked computers operated by cybercriminals. Bot herders scan for vulnerabilities, infect systems, and use them for malicious activities, such as DDoS (Distributed Denial-of-Service) attacks. EG the Mirai botnet in 2016 that infected IoT devices, leading to a massive DDoS attack. Denial-of-Service (DoS) & Distributed Denial-of-Service (DDoS) Attacks:  These attacks overwhelm a system with requests, making it unavailable for the average person to use, it can be: Application-layer flooding: In this attack type, an attacker simply floods the service with requests from a spoofed IP address in an attempt to slow or crash the service Unintended DoS (accidental overuse) DDoS (many computers attacking one target) EG...

Test yourself 241  A botnet aims to take control of digital systems. It is a type of malware that allows a cyber security attacker to take control of someone's system without their knowledge.   The aim of a DOS attack is to make a network inaccessible to users. It does this by flooding the network with traffic which in turn slows its speeds down to a point where it is basically unusable.  One of the main differences between a DOS attack and a DDOS attack is a DDOS attack tends to use multiple devices to try and infiltrate a network. The types of networks that are usually under threat from these would be ones like websites, banks, and payment websites.   Some of the main websites that are targeted by DDOS attacks would be ones like banks and payment websites.   Test yourself 242 One way of trying to find a password is using a dictionary software. This goes through some of the most common passwords and trying them when trying to get access to the account....
