why is the speed of malicious attacks making the challenge of keeping computers secure more difficult?
The speed of malicious attacks is making the challenge of keeping computers secure more difficult because;
attackers are constantly developing new and sophisticated methods to exploit vulnerabilities in computer systems.
These methods are becoming more advanced and automated, making it harder for defenders to detect and respond to them in a timely manner.
Additionally, the increasing connectivity and interdependence of computer systems makes it easier for attackers to spread malware and launch attacks across multiple systems, making it even harder to contain and mitigate the damage.
Another factor that makes it more difficult to keep computers secure is the speed at which attacks can be launched. In the past, it might have taken days or weeks for an attacker to launch an attack. Now, with the use of automation and the internet, an attacker can launch an attack in a matter of minutes or even seconds. This makes it harder for defenders to respond quickly enough to stop the attack.
In summary, the speed of malicious attacks and the constantly changing landscape of threats, along with the growing interconnectedness of devices and systems and the use of automation and AI in cyber-attacks, make it more difficult to keep computers secure.

your team is meeting to prioritize user stories for a coming iteration. each team member has a set of cards with numerical weights associated to them and has been asked to ranked the user stories based on complexity. as each user story is read, each team member flips over their card to indicate their ranking. those that have given the user story a high rating and low rating are given an opportunity to quickly make their point to the team. this process is repeated until a consensus is reached. what tool is described?
The tool described is Planning Poker. It is a consensus-based technique used by agile development teams to estimate the relative effort or size of development goals in software development. Each team member uses cards with numerical weights, such as the Fibonacci sequence, to indicate their estimation of the complexity of a user story. The team members flip over their cards simultaneously, and any outliers, high or low values, are given an opportunity to explain their reasoning to the team. The process is repeated until a consensus is reached on the complexity of the user story. Planning Poker is often used in Scrum and other agile methodologies to plan and prioritize the work that needs to be done in an upcoming iteration.

what is binary notation of 5
In binary notation, 5 is represented as "101".
Binary is a base-2 number system, which means that it uses only two digits, 0 and 1, to represent all values. Each digit in a binary number represents a power of 2. The rightmost digit represents 2^0 (or 1), the next digit to the left represents 2^1 (or 2), the next digit represents 2^2 (or 4) and so on.
To convert a decimal number (such as 5) to binary, the number is repeatedly divided by 2 and the remainder is recorded. The process is continued until the quotient is 0. The remainders are then read from bottom to top to obtain the binary representation of the number.
In the case of 5:
5 divided by 2 is 2 with a remainder of 1. So the first digit is 1.2 divided by 2 is 1 with a remainder of 0. So the second digit is 0.1 divided by 2 is 0 with a remainder of 1. So the third digit is 1.So the binary notation of 5 is "101".
