What is Cybersecurity & why it’s so important? Cybersecurity also referred to as information technology security is the process, and practices designed to protect networks, devices, programs, and data from attack, damage, or unauthorized access. It’s important because of most of the institutions like government, military, corporate, financial, and medical collect, process, and store a huge number of data on their servers, and most of the time they carry a significant portion of sensitive data. While doing businesses the organizations have to transmit those sensitive data across the network. Therefore, cybersecurity is dedicated to protecting the information and the system used to process and store it. So how to protect this information? Therefore, to protect these systems and information we must build powerful firewalls and safe logins with strong passwords. To be a cybersecurity system effective, an organization needs to coordinate its efforts throughout its entire information system which consists…

Do you think that your applications are secure? A vulnerability is a weakness or a hole in the application, which can be a design flaw or an implementation bug, that allows an attacker to cause harm to the stakeholders of an application. Application vulnerabilities are not the same as other common types of vulnerabilities, such as network or asset. They arise because web applications need to interact with multiple users across multiple networks, and that level of accessibility is easily taken advantage of by hackers. In cybersecurity, a vulnerability is a weakness that can be exploited by a cyber attack to gain unauthorized access or perform unauthorized actions on a computer system. Vulnerabilities can allow attackers to run code, access a system’s memory, install malware and steal, destroy or modify sensitive data. It means a system flaw or weakness in an application that could be exploited to compromise the security of the application.…

With the technological advancements that are rapidly taking control over the world, we are progressing towards an era where absolutely anything and everything is bound by technology. Most valuable or confidential information is either stored in computers, computer-based systems, or other digital storage devices, which has led to the exponential growth of digital or cybercrimes. As a result, there surfaced the need for a forensic discipline to investigate such computer-based crimes. This gave rise to the discipline of Computer Forensics which emerged as a branch of Digital Forensic Science, to analyze digital media in order to locate, preserve, collect, interpret and present information and observations on digital content. What is Computer Forensics? Forensics is the practice of using analytical expertise to gather, examine, and present evidence to the courts. The word “Forensics”, which has a Latin origin, has the meaning, “to bring to the court”. Forensics primarily concerns the retrieval…

A Denial-of-Service (DoS) attack is an attack meant to shut down a machine or network, making it inaccessible to its intended users. DoS attacks accomplish this by flooding the target with traffic or sending it information that triggers a crash. Victims of DoS attacks often target web servers of high-profile organizations such as banking, commerce, and media companies, or government and trade organizations. When a website suffers a DoS attack, the apparent effect will depend on your perspective. For the average user, it appears that the site has simply stopped displaying content. For businesses, it could mean that the online systems they depend upon have ceased to respond. The symptoms of a DoS attack against industrial control systems may include the inability to retrieve sensor data, or control critical processes. Though DoS attacks do not typically result in the theft or loss of significant information or other assets, they can…

Does increased security provide comfort to paranoid people? Or does security provide some basic protections that we are naive to believe that we don’t need? During these times when the internet provides essential communication between literally billions of people and is used for social interaction, commerce, and exchange of personal information, security has become a tremendously important issue for every user. There are many aspects to security and many applications. One essential aspect of secure communication is Cryptography. WHAT IS CRYPTOGRAPHY? Cryptography – the science of secret writing, is an ancient art, the first documented use of cryptography in writing dates back to circa 1900 B.C. When an Egyptian scribe used non-standard hieroglyphs in an inscription. Some experts argue that cryptography appeared spontaneously sometime after writing was invented, with applications ranging from diplomatic missives to war-time battle plans. It is no surprise, then, that new forms of cryptography came soon after…

Encryption Encryption is the process of encoding information which means the translation of data into secret code. Encryption is an effective way to reach data security. To access/read an encrypted file we must have access to a secret key that enables us to decrypt it. Encrypted virus A  computer virus that encrypts its effects on a computer system with the intention of making detecting the virus more difficult.  If the file is opened it will execute the virus payload(effects of the virus on the system), which is poisonous code. The ransomware runs the code that encrypts user data on the infected computer. The only way it can be recovered is with the decryption key. What is Ransomware It is an encrypted virus designed to block access to a computer system until an amount of money is paid. This is also an encrypted virus. Through the use of techniques called phishing, a threat actor…
