What are the Password Attacks in Information Security?
A Password attack contains multiple techniques used by hackers to steal passwords. There are some password attacks are as follows −Brute-force − It is method in which a hacker attempt to guess a password by frequently entering in new set of words and phrases compiled from a dictionary to steal the password. It is making complex to guess usernames and passwords can avoid it.Packet sniffers − Packet sniffers are the technique used to capture data streams over a network to acquire sensitive information like usernames, passwords, credit card numbers, etc. Therefore, packet sniffers are also malicious forms of threats to ...
Read MoreC++ program to find minimum difference between the sums of two subsets from first n natural numbers
Suppose we have a number n. Consider, first n natural numbers. We have to split them into two sets A and B such that each element belongs to exactly one set and the absolute difference between the sum of elements in A and sum of elements in B is minimum, and find that difference.So, if the input is like n = 5, then the output will be 1, because if we make A = {1, 3, 4} and B = {2, 5}, then the sum values are 8 and 7, so difference is 1.StepsTo solve this, we will follow these ...
Read MoreC++ program to count number of stairways and number of steps in each stairways
Suppose we have an array A with n elements. Let, Amal climbs the stairs inside a multi-storey building. Every time he climbs, start counting from 1. For example, if he climbs two stairways with 3 steps and 4 steps, he will speak the numbers like 1, 2, 3, 1, 2, 3, 4. In the array A, the numbers are representing stair numbers said by Amal. We have to count the number of staircase did he climb, also print the number of steps in each stairway.So, if the input is like A = [1, 2, 3, 1, 2, 3, 4, 5], ...
Read MoreC++ program to find indices of soldiers who can form reconnaissance unit
Suppose we have an array A with n elements. There are n soldiers standing on a circle. For ith soldier, the height is A[i]. A reconnaissance unit can be made of such two adjacent soldiers, whose heights difference is minimal. So each of them will be less noticeable with the other. We have to find the indices of the pair of soldiers that can form a reconnaissance unit.So, if the input is like A = [10, 12, 13, 15, 10], then the output will be (5, 1).StepsTo solve this, we will follow these steps −n := size of A D ...
Read MoreHow does Security Information Management Works in information security?
Security information management is a type of software that automates the set of event log data from security devices, including firewalls, proxy servers, intrusiondetection systems, and anti-virus applications. 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.All Security Information Managements gather data from the sources inside the network. Some will gather data from outside sources as well, ranging from public threat recognition services to proprietary correlation networks. Security Information Management, to a high extent, adds value with its capacity of discovering patterns in network ...
Read MoreC++ program to find order of loading golds on weight scale without exploding it
Suppose we have an array A with n distinct elements, and another number x. There are n pieces of gold. The ith gold weight is A[i]. We will put this n pieces on weight scale one piece at a time. But the scale has an unusual defect: if the total weight on it is exactly x, it will explode. We have to check whether we can put all n gold pieces onto the scale in some order, without exploding the scale during the process. If we can, find that order. If not possible, mark "IMPOSSIBLE".So, if the input is like ...
Read MoreWhat is the importance of Security Information Management in information security?
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, ...
Read MoreC++ program to check xor game results 0 or not
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 MoreWhat is SIM in information security?
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 MoreWhat is the role of Internet and Web Service in Information Security?
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 ...
