Working on a vulnerability assessment tool works : A vulnerability assessment tool works in the following way as follows. • Classifies the system resources. • Allocates the enumerable values to the classified resources. • Detects the possible threats (vulnerabilities) in each resource. • Eliminates the vulnerabilities on a priority basis. Features : • It allows an attacker to cause undesirable operations or gain unauthorized access. • Open VAS is a framework that is licensed under the GNU General Public License (GNU GPL). • It is based on a client-server architecture that works on the basis of OpenVAS Transfer Protocol (OTP), Open VAS Management Protocol (OMP), and Open VAS Administrative Protocol (OAP). Categories of Open VAS architecture : Open VAS architecture has the following categories as follows. • Clients – Open VAS CLI and Green-bone Security Assistant (GSA) are interfaces available for clients.| • Services – Open VAS Scanner and Open VAS Manager are services that actually perform the tasks of scanning the host machine on the network for Network Vulnerability Tests (NVTs). • Data – NVTs results and configs are data used in the process of scanning the host machine.

What is Cyber Security? The technique of protecting internet-connected systems such as computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks is known as cybersecurity. We can divide cybersecurity into two parts one is cyber, and the other is security. Cyber refers to the technology that includes systems, networks, programs, and data. And security is concerned with the protection of systems, networks, applications, and information. In some cases, it is also called electronic information security or information technology security. Some other definitions of cybersecurity are: "Cyber Security is the body of technologies, processes, and practices designed to protect networks, devices, programs, and data from attack, theft, damage, modification or unauthorized access." "Cyber Security is the set of principles and practices designed to protect our computing resources and online information against threats." Types of Cyber Security Every organization's assets are the combinations of a variety of different systems. These systems have a strong cybersecurity posture that requires coordinated efforts across all of its systems. Therefore, we can categorize cybersecurity in the following sub-domains: • Network Security: It involves implementing the hardware and software to secure a computer network from unauthorized access, intruders, attacks, disruption, and misuse. This security helps an organization to protect its assets against external a...

Because email is the most used mode of communication, according to Statista, 4.03 billion people will use email in 2021, and that number is expected to climb to 4.48 billion by 2024. Every day, emails are sent and received across devices, necessitating the need to secure these interactions. Because of the amount and type of sensitive data in a commercial firm, this criticality is increased. Assume you work in a field where sensiti...

A salami attack is a method of cybercrime that attackers or a hacker typically used to commit financial crimes. Cybercriminals steal money or resources from financial accounts on a system one at a time. This attack occurs when several minor attacks combine to create a sturdy attack. because of this sort of cybercrime, these attacks frequently go undetected. Salami attacks are used for the commission of economic crimes Those who are found guilty of such an attack face punishment under Section 66 of the IT Act. Working of Salami attack: During this kind of attack, an awfully insignificant change is introduced that goes completely unnoticed. as an example, a bank accountant inserts a program, into the bank’s servers, that deducts a satiny low amount of cash from the account of each customer. No account holder will probably notice this Unauthorized debit, but the bank accountant will make an outsized amount of cash each month. as an example, an employee of a bank in the USA was terminated from his job. Disgruntled at having been supposedly mistreated by his employers the person first introduced a logic bomb into the bank’s systems. Types of Salami attacks: • Salami Slicing: Salami Slicing occurs when the • Penny Shaving: when the Prevention From Salami attack: Users are encouraged to oversee their weekly transactions and month-to-month bank statements to shield their bank accounts from being hindered by a salami attack. you’ll monitor any potential charges on your account by a...

Cross Site Scripting (XSS) is a vulnerability in a web application that allows a third party to execute a script in the user’s browser on behalf of the web application. Cross-site Scripting is one of the most prevalent vulnerabilities present on the web today. The exploitation of XSS against a user can lead to various consequences such as account compromise, account deletion, privilege escalation, malware infection and many more. In its initial days, it was called CSS and it was not exactly what it is today. Initially, it was discovered that a malicious website could utilize JavaScript to read data from other website’s responses by embedding them in an iframe, run scripts and modify page contents. It was called CSS (Cross Site Scripting) then. The definition changed when Netscape introduced the Same Origin Policy and cross-site scripting was restricted from enabling cross-origin response reading. Soon it was recommended to call this vulnerability as XSS to avoid confusion with Cascading Style Sheets(CSS). The possibility of getting XSSed arises when a website does not properly handle the input provided to it from a user before inserting it into the response. In such a case, a crafted input can be given that when embedded in the response acts as a JS code block and is executed by the browser. Depending on the context, there are two typesof XSS – • Reflected XSS: If the input has to be provided each time to execute, such XSS is called reflected. These attacks are mostly carr...

Cyberattacks are frequently making headlines in today's digital environment. At any time, everyone who uses a computer could become a victim of a cyber attack. There are various sorts of What is a Botnet? The words "robot" and "network" together give rise to the term Botnet. Botnet refers to a network of hijacked internet-connected devices that are installed with malicious codes known as malware. Each of these infected devices is known as Bots, and a hacker/cybercriminal known as the "Bot herder" remotely controls them. A bot is also called a zombie, and a botnet is referred to as a zombie army. The bot herder can direct every bot to carry out a coordinated illegal action from a single central location. A botnet can have several bots and thus allows the attacker to carry out large-scale attacks. Infected devices can acquire updates and modify their behavior easily and quickly since a remote attacker controls them. The bots are used to automate large-scale attacks, including data theft, server failure, malware propagation, spam email generation, and malicious traffic generation for distributed denial-of-service (DDoS) attacks. How Does a Botnet Work? Now that you have a good understanding of what is a botnet, it’s time to dive deeper into learning how a botnet works. Below are the steps that are carried out to initiate a botnet attack: • Prepping the Botnet Army: The first step in creating a botnet is to infect as many connected devices as possible, to ensure that there are...

Steganography definition Steganography is a millennia-old concept that means hiding a secret message within an ordinary-looking file that doesn't raise any suspicions. The word has Greek roots, being a combination of steganos, which translates to "concealed, protected ," and graphein, which means "writing." APT groups, ransomware gangs, and other threat actors often hide information when attacking a target. For example, they might conceal data when exfiltrating it, cloak a malicious tool, or send instructions for command-and-control servers. They could put all this information in unassuming image, video, sound, or text files. Steganography has a critical advantage over cryptography: In cryptography, you know the secret message is there, only its content is concealed; in steganography, the existence of the secret message is often difficult to notice. Threat actors sometimes use the two techniques together, encrypting a message before sneaking it inside a file. How steganography works Steganography is one way malicious actors fly under the radar. "We often see it being used as the initial entry point, and once the threat actors are in the network, there are more tools and code that they will use to move laterally," Jon Clay, vice president of threat intelligence at Trend Micro, says. Frequently, the secret data is cleverly hidden inside an image by manipulating a few bits. Still, if users look at the original photo and compare it with the altered one, they can't tell the dif...

What is the Cyber Kill Chain? The cyber kill chain is an adaptation of the military’s kill chain, which is a step-by-step approach that identifies and stops enemy activity. Originally developed by Lockheed Martin in 2011, the cyber kill chain outlines the various stages of several common cyberattacks and, by extension, the points at which the information security team can prevent, detect or intercept attackers. The cyber kill chain is intended to defend against sophisticated cyberattacks, also known as 2023 CrowdStrike Global Threat Report The 2023 Global Threat Report highlights some of the most prolific and advanced cyber threat actors around the world. These include nation-state, eCrime and hacktivist adversaries. Read about the most advanced and dangerous cybercriminals out there. 8 Phases of the Cyber Kill Chain Process Lockheed Martin’s original cyber kill chain model contained seven sequential steps: Phase 1: Reconnaissance During the Reconnaissance phase, a malicious actor identifies a target and explores vulnerabilities and weaknesses that can be exploited within the network. As part of this process, the attacker may harvest login credentials or gather other information, such as email addresses, user IDs, physical locations, software applications and operating system details, all of which may be useful in phishing or spoofing attacks. Generally speaking, the more information the attacker is able to gather during the Reconnaissance phase, the more sophisticated and...
