An ethical hacker is a specialist with in-depth technical knowledge and talents specifically skilled at identifying and exploiting flaws in target systems. The proprietors of the designs have permitted him to work. An ethical hacker's goal is to evaluate the security posture of a target organization or system, and they must abide by the laws of the target owner and the company. It's like a secret shopper. They go into stores covertly to look for issues and give comments on what needs to be fixed. To test a store's security, secret shoppers may even simulate thefts. Similarly, firms that wish ...

In Perl, there are two ways to check if two arrays are equal. We can compare two arrays in Perl with the help of "Storable freeze" function or by creating our own custom function. In this tutorial, we will explore both these approaches with the help of examples. Example 1 Let's first explore the "Storable freeze" code and understand how it works. Consider the code shown below. use Storable qw/freeze/; use strict; $Storable::canonical = 1; my @countriesOne = ('India', 'China', 'Russia', 'USA', 'Germany'); my @countriesTwo = ('India', 'China', 'Russia', 'USA', 'Germany'); my @countriesThree = ...

Suppose we get a variable at runtime in Perl and we want to check if the value that it contains is numeric or not, then we can use the two approaches shown in this tutorial. We will use two simple examples to demonstrate how it works. Example The most basic approach is to use the length and do keywords and then ignore the warnings. Consider the code shown below for the same. $x = 100; if (length(do { no warnings "numeric"; $x & "" })){ print "x is numeric"; } else { print ... Read More
Nowadays, safeguarding precious data from cybercriminals has never been so essential in this modern world. An organization has vast data, and it is challenging to manage all that without a structured plan. Any organization's IT professionals cannot do it on their own. Hence, they rely on something called Cyber Security Framework. We will discuss many of these Cyber Security Frameworks here, and you'll walk away knowing all the core concepts of these frameworks. What is a Cyber Security Framework? These documents describe guidelines, standards, and best practices for cyber security risk management. These frameworks reduce an organization's exposure to weaknesses ... Read More
Let's consider a scenario where we would want to know if a Perl hash already contains a key or not. To do so in Perl, we can use the exists() function. In this tutorial, we will explore the exists function with the help of two examples. The exists() Function in Perl In Perl, the exists() function checks whether a particular element exists or not in an array or a hash. If the requested element appears in the input array or hash, this function returns "1", else it returns "0". Example 1 Consider the code shown below. In this example, we ... Read More
In Perl, we can check whether an array contains a particular value or not with the help of the "grep" keyword. The grep function in Perl is used to filter the input supplied in the function as a parameter out of the list of items. Similar to Linux, it uses the given input to find the matching value. The grep() Method "grep" is a built-in function in Perl, we can pass our regular expression inside this function. It will check the input for matching values and return a list based on whether the condition is true or false. Syntax As ... Read More
In most programming languages, we can use the "break" keyword to break out of any type of loop. In Perl too, we have the "break" keyword available, but the keyword that is used the most to break out of a loop is the "last" keyword. The "last" Statement in Perl The "last" statement is used in Perl loops to exit a loop immediately; it is the equivalent of the "break" statement in C/C++ and Java. In practice, you often use the "last" statement to exit a loop if one of the conditions is met, for example, you find an ... Read More
Cybersecurity professionals use every available technological edge when formulating a plan to counteract the persistent threats posed by hackers and other cybercriminals. Artificial intelligence (AI) and machine learning (ML) are two cutting-edge technologies that have completely altered the cyber security landscape. The majority of organizations (63%) use machine learning in some capacity, 82% report a financial return on their AI investment, and 88% want to boost AI expenditure this year, as per the Deloitte State of AI in the Enterprise Survey. As for the use of ML and AI in the business world of cyberspace, where exactly would you look ... Read More
There is a lot to study if you want to become a complete security professional. Training in ethical hacking is a fantastic place to begin, but if you want to stand out to potential employers or are simply interested in improving your skills, you should check for ECSA certification. Even if you already have a job in cybersecurity, you should familiarize yourself with ECSA v10. An ECSA course dramatically increases your value to potential employers and knowledge base. What is ECSA? The ECSA certification program develops on the foundation of certifications such as the Certified Ethical Hacker (CEH). It's a ... Read More
Companies are becoming more optimistic about their ability to translate increased IT productivity into tangible cost reductions as they modernize their internal information technology (IT) infrastructures by incorporating game-changing new technologies and industry-standard best practices. It is because these technologies are becoming more accessible and affordable. It is because firms are developing increased confidence in fulfilling these obligations. It is due to the technologies mentioned above being less prohibitively costly and more easily accessible in the present day and age. The IT organization's future looks brighter than ever for several reasons, some of which include enhanced service quality, big data, ... Read More
