Security information management is a type of software that automates the collection of event log data from security devices, such as firewalls, proxy servers, intrusion detection systems, and anti-virus software. The goals of Security Information Management are to avoid interruptions to business events and provide the correct and secure services of computer and network facilities.Information technology is not only the necessity of our lives but it has more essential for our business as well. The essential asset of an organization is Information and to provide confidentiality and integrity of the valuable and important information and operational procedure in an organization, ...

Suppose we have an array A with N elements and another binary string S. Consider two players are playing a game. They are numbered as 0 and 1. There is one variable x whose initial value is 0. The games has N rounds. In ith round person S[i] does one of the following: replace x with x XOR A[i], otherwise do nothing. Person 0 wants 0 at the end of this game but person 1 wants non-zero. We have to check whether x becomes 0 at the end or not.So, if the input is like A = [1, 2]; S ... Read More
SIM stands for Security Information Management. Security information management is a type of software that automates the set of event log data from security devices, including firewalls, proxy servers, intrusion-detection systems and anti-virus applications.The SIM interprets the logged information into the correlated and simplified structure. Some SIM mechanism supports security documenting, analysis, and documenting for Sarbanes-Oxley, HIPAA, Basel II, FISMA, and Visa CISP compliance audits.A SIM automates group and analysis of data from some security elements in a network. Instead of having to view logs and alerts from the firewall, IDS, anti-virus, VPN, and some security systems, a security manager ... Read More
Internet is considered as the most essential thing for people these days. All the systems and spheres are incompletely or completely dependent on the Internet. Let us consider the world’s banking system, for example, people do not usually think of how all the financial functions in the world are performed out. Generally, all the financial functions and transfers would be unworkable without the authority of the Internet.If the Internet stops functioning, everything fails and the entire system stops. If the Internet stopped working all over the world one day, it can be a real disaster, and some companies, organizations, and ... Read More
Suppose we have two strings S and T. Both are in lowercase letters. Concatenate T and S in this order to generate the final string.So, if the input is like S = "ramming"; T = "prog", then the output will be "programming"StepsTo solve this, we will follow these steps −res := T concatenate S return resExampleLet us see the following implementation to get better understanding −#include using namespace std; string solve(string S, string T){ string res = T + S; return res; } int main(){ string S = "ramming"; string T = "prog"; cout
A management information system is a refined direction of available sources of information that allows managers to tie planning and control processes to operational systems of implementation.A management information system (MIS) is a generally used and used term for a three-resource system needed for efficient organization management. The resources are people, information, and technology, from within and external an organization, with the highest priority provided to people.The system is a set of information management techniques containing computer automation (software and hardware) or otherwise providing and enhancing the quality and effectiveness of business services and human decision-making.An MIS can be used ...

Suppose we have a list of N coordinate points P in the form (xi, yi). The x and y values are permutation of first N natural numbers. For each k in range 1 to N. We are at city k. We can apply the operations arbitrarily many times. The operation: We move to another city that has a smaller x-coordinate and a smaller y-coordinate or larger x or larger y coordinate than the city we are currently in. We have to find the number of cities we can reach from city k.So, if the input is like P = [[1, ... Read More
An information system is the application of data production, flows, and use inside organizations. Information system creates huge use of data technology defines. But it is essential to appreciate that its capacity encompasses systems in their entirety, such as manual events, the interface among manual and automated elements of systems, design elements of IT means, and economic, legal, organizational, behavioural, and social elements of systems.Information systems overlap with both the computer science and business administration disciplines. The information system of an organization can be represented as a system that serves to support data within the organization when and where it ... Read More
Suppose we have five numbers, N, A, B, C, D. We start with a number 0 and end at N. We can change a number by certain number of coins with the following operations −Multiply the number by 2, paying A coinsMultiply the number by 3, paying B coinsMultiply the number by 5, paying C coinsIncrease or decrease the number by 1, paying D coins.We can perform these operations any number of times in any order. We have to find the minimum number of coins we need to reach NSo, if the input is like N = 11; A = ... Read More
Suppose we have four numbers n, x, a and b. There are n students in the row. There are two rivalling students among them. One of them is at position a and another one is at position b. Positions are numbered from 1 to n from left to right. We want to maximize the distance between these two students. We can perform the following operation x times: Select two adjacent students and then swap them. We have to find the maximum possible distance after x swaps.So, if the input is like n = 5; x = 1; a = 3; ... Read More
