How To Browse Safely On The Deep And Dark Web.

Google only indexes a tiny fraction of the internet. By some estimates, the web contains 500 times more content than what Google returns in search results. The links that Google and other search engines return when you type in a query is known as the “surface web,” while all the other, non-searchable content is referred to as the “deep web” or “invisible web”. The dark net, or dark web, constitutes a small fraction of the deep web. The dark web is made up of purposefully hidden websites and services. Both the owners and users of the dark web are anonymous. Although not everything on the dark net is illegal, it’s where you’ll find many of the internet’s black markets, hacker forums, malware vendors, and other illicit activity. What is the deep web?  The deep web is just like it sounds — below the surface and not completely dark. What’s on the deep web? The deep web holds the content that’s […]

What is Computer Security? Computer security, also known as cybersecurity or IT security, is the protection of information systems from theft or damage to the hardware, the software, and to the information on them, as well as from disruption or misdirection of the services they provide. It includes controlling physical access to the hardware, as well as protecting against harm that may come via network access, data and code injection, and due to malpractice by operators, whether intentional, accidental, or due to them being tricked into deviating from secure procedures. What are the concerns of computer security? Computer Security is concerned with four main areas:1. Confidentiality:- Only authorized users can access the data resources and information.2. Integrity:- Only authorized users should be able to modify the data when needed.3. Availability:- Data should be available to users when needed.4. Authentication:- are you really communicating with whom you think you are communicating with Why is computer security important? Prevention of data theft […]



Viruses, worms, Trojans, and bots are all part of a class of software called “malware.” Malware is short for “malicious software,” also known as malicious code or “malcode.” It is code or software that is specifically designed to damage, disrupt, steal, or in general inflict some other “bad” or illegitimate action on data, hosts, or networks. There are many different classes of malware that have varying ways of infecting systems and propagating themselves. Malware can infect systems by being bundled with other programs or attached as macros to files. Others are installed by exploiting a known vulnerability in an operating system (OS), network device, or other software, such as a hole in a browser that only requires users to visit a website to infect their computers. The vast majority, however, are installed by some action from a user, such as clicking an email attachment or downloading a file from the Internet. Some of the more commonly known types of malware are […]



Firewalls are network devices that help enforce an organization’s securitypolicy. Since their development, various methods have been used toimplement firewalls. These methods filter network traffic at one or moreof the seven layers of the ISO network model, most commonly at theapplication, transport, network, and data-link levels. Newer methods,which have not yet been widely adopted, include protocol normalizationand distributed firewalls.Firewalls involve more than the technology required to implementthem. Specifying a set of filtering rules, known as a policy, is typicallycomplicated and error prone. High-level languages have been developedto simplify the task of correctly defining a firewall’s policy. Once a policyhas been specified, testing is required to determine if the firewall correctlyimplements it.Because some data must be able to pass in and out of a firewall forthe protected network to be useful, not all attacks can be stopped byfirewalls. Some emerging technologies, such as virtual private networks(VPNs) and peer-to-peer networking, pose new challenges to existingfirewall technology. TYPES OF FIREWALLS Packet-filtering firewalls Circuit-level […]



What is cyberwar? Cyberwarfare refers to the use of digital attacks — like computer viruses and hacking — by one country to disrupt the vital computer systems of another, with the aim of creating damage, death and destruction. Future wars will see hackers using computer code to attack an enemy’s infrastructure, It also involves the actions of a nation-state or international organization to attack and attempt to damage another nation’s computers or information networks through, for example, computer viruses or denial-of-service attacks. RAND research provides recommendations to military and civilian decisionmakers on methods of defending against the damaging effects of cyber warfare on a nation’s digital infrastructure. A short history of cyberwarfair For many people, 2007 was when cyberwar went from the theoretical to the actual. When the government of the eastern European state of Estonia announced plans to move a Soviet war memorial, it found itself under a furious digital bombardment that knocked banks and government services offline (the […]



Foot Printing in Security terms is the process of gathering as much possible information about the Target Organization Footprinting is a part of reconnaissance process which is used for gathering possible information about a target computer system or network. Footprinting could be both passive and active. Reviewing a company’s website is an example of passive footprinting, whereas attempting to gain access to sensitive information through social engineering is an example of active information gathering. Footprinting is basically the first step where hacker gathers as much information as possible to find ways to intrude into a target system or at least decide what type of attacks will be more suitable for the target. During this phase, a hacker can collect the following information − Domain name IP Addresses Namespaces Employee information Phone numbers E-mails Job Information Objectives of Footprinting are as follows To Collect Network Information To Collect System Information To Collect Organizations Information TYPES AND METHODS OF FOOTPRINTING Footprinting through […]



Identity theft is when someone steals your personal information and uses it without your permission. There are several forms of identity theft, and each one can affect you in a different way. There’s no way to inoculate yourself against identity theft completely. But if you’re diligent in learning how your information can be at risk and what fraudsters can do with it, you’ll be better equipped to protect your data and act quickly if someone does manage to steal it. It is the crime of obtaining the personal or financial information of another person for the sole purpose of assuming that person’s name or identity to make transactions or purchases It is also the unauthorized use of someone’s personal data or documents (usually social security card or credit cards) to obtain merchandise, services or credit. 1. Driver’s License Identity Theft Driver’s license theft is the most common form of ID theft. The person who stole your ID may try to […]



Description: To better describe hacking, one needs to first understand hackers. One can easily assume them to be intelligent and highly skilled in computers. In fact, breaking a security system requires more intelligence and expertise than actually creating one. There are no hard and fast rules whereby we can categorize hackers into neat compartments. However, in general computer parlance, we call them white hats, black hats and grey hats. White hat professionals hack to check their own security systems to make it more hack-proof. In most cases, they are part of the same organisation. Black hat hackers hack to take control over the system for personal gains. They can destroy, steal or even prevent authorized users from accessing the system. They do this by finding loopholes and weaknesses in the system. Some computer experts call them crackers instead of hackers. Grey hat hackers comprise curious people who have just about enough computer language skills to enable them to hack a […]


How To Unlock BIOS Password

How to Reset / Remove / Bypass Forgotten BIOS or CMOS Password? A BIOS password is a protective measure that can be used to prevent someone powering up a computer system or making changes in some of the computers most sensitive areas. Many big name computer manufacturers such as Dell and HP lock the customers out of this area because they don’t want the customer changing anything and potentially damaging the machine (which the manufacturer may have to warranty). However, when someone like a computer technician or hardware enthusiast needs to make some hardware changes to the computer, they will need to access the BIOS. Here are some methods to be a bios password cracker, removing a BIOS password. BIOS passwords are used to add some extra security to computers. You can either set a password to prevent access to BIOS settings or to prevent PC from booting. But sometimes this extra security might become a pain when you forget […]

Cross-site Scripting (XSS) Cross-site scripting (also known as XSS) is a web security vulnerability that allows an attacker to compromise the interactions that users have with a vulnerable application. It allows an attacker to circumvent the same origin policy, which is designed to segregate different websites from each other. Cross-site scripting vulnerabilities normally allow an attacker to masquerade as a victim user, to carry out any actions that the user is able to perform, and to access any of the user’s data. If the victim user has privileged access within the application, then the attacker might be able to gain full control over all of the application’s functionality and data. Cross-site Scripting (XSS) is a client-side code injection attack. The attacker aims to execute malicious scripts in a web browser of the victim by including malicious code in a legitimate web page or web application. The actual attack occurs when the victim visits the web page or web application that […]



Web application security remains a major roadblock to universal acceptance of the Web for many kinds of online transactions, especially since the recent sharp increase in remotely exploitable vulnerabilities has been attributed to Web application bugs. In software engineering, software testing is an established and well-researched process for improving software quality. Recently, formal verification tools have also shown success in discovering vulnerabilities in C programs. In this chapter we shall discuss how to apply software testing and verification algorithms to Web applications and improve their security attributes. Two of the most common Web application vulnerabilities that are known to date are script injection, e.g., SQL injection, and cross-site scripting (XSS). We will formalize these vulnerabilities as problems related to information flow security—a conventional topic in security research. Using this formalization, we then present two tools, WAVES (Web Application Vulnerability and Error Scanner) and Web-SSARI (Web Application Security via Static Analysis and Runtime Inspection), which respectively utilize software testing and verification […]


How To Protect Your Website Against SQL Injection Attack

The SQL INJECTION vulnerability is one of the most dangerous issues for data confidentiality and integrity in web applications and has been listed in the OWASP Top 10 list of the most common and widely exploited vulnerabilities since its inception SQL Injection is a hacking technique that was discovered many years ago and is still proving to be devastatingly effective today, remaining a top database security priority. It was used in the run-up to the 2016 U.S. presidential election to compromise the personal data of 200,000 Illinois voters, as well as in high-profile attacks against organizations such as Sony Pictures, PBS, Microsoft, Yahoo, Heartland Payment Systems, and even the CIA. SQL, or Structured Query Language, is the command-and-control language for relational databases such as Microsoft SQL Server, Oracle, and MySQL.

Wireless network security primarily protects a wireless network from unauthorized and malicious access attempts. Typically, wireless network security is delivered through wireless devices (usually a wireless router/switch) that encrypts and secures all wireless communication by default. Even if the wireless network security is compromised, the hacker is not able to view the content of the traffic/packet in transit. Moreover, wireless intrusion detection and prevention systems also enable protection of a wireless network by alerting the wireless network administrator in case of a security breach. Hacking wireless net work to get free internet is now prevalent burt with the underlisted free security and monitoring tools,your network is secure Security managers have a variety of tools available for keeping WLANs safe.

A man-in-the-middle attack is a type of cyberattack where a malicious actor inserts him/herself into a conversation between two parties, impersonates both parties and gains access to information that the two parties were trying to send to each other. A man-in-the-middle attack allows a malicious actor to intercept, send and receive data meant for someone else, or not meant to be sent at all, without either outside party knowing until it is too late. Man-in-the-middle attacks can be abbreviated in many ways, including MITM, MitM, MiM or MIM. A man-in-the-middle attack requires three players. There’s the victim, the entity with which the victim is trying to communicate, and the “man in the middle,” who’s intercepting the victim’s communications. Critical to the scenario is that the victim isn’t aware of the man in the middle. How does a man-in-the-middle attack work? How does this play out? Let’s say you received an email that appeared to be from your bank, asking you […]


How to create a WordPress customer database.

A database is an organized collection of structured information, or data, typically stored electronically in a computer system. A database is usually controlled by a database management systemCDBMS). Together, the data and the DBMS, along with the applications that are associated with them, are referred to as a database system, often shortened to just database. Data within the most common types of databases in operation today is typically modeled in rows and columns in a series of tables to make processing and data querying efficient. The data can then be easily accessed, managed, modified, updated, controlled, and organized. Most databases use structured query language (SQL) for writing and querying data. Participants Database is designed to let you store information about anything in general – it’s not limited to customers. It accomplishes this because it’s incredibly flexible in the information that it tracks. In fact, you’ll be able to configure literally every field that you store data for.

Microsoft Office remains the most popular productivity suite for documents, spreadsheets, presentations, and more – whether as a download software package, or as the cloud-based Microsoft 365 suite. However, a range of alternative competitors have become increasingly attractive, not least because of more price-competitive licensing fees, and some are free to use. However, paying less, or nothing, doesn’t necessarily mean that the software is of lower quality, as the open source community can testify. Yet there can be issues with sharing documents between different office suite platforms, which can be a real concern. This is why when choosing an alternative to Microsoft Office, you need to be certain of any shortfalls that might limit your use of the software, especially if you need to share or collaborative on documents with other users who have one or more different office suites. If you’re using the office alternative as a standalone piece of software there shouldn’t be any such issues, but it […]


What Is Sms Phishing Attack

SMS phishing is a situation when a cell phone receives a SMS (Instant Message or IM) from a fake person or entity. The unsuspecting cell phone user will respond to a fake SMS and visit a URL, inadvertently downloading malware and installing a Trojan without the user’s knowledge. Phishing is all about extracting useful information, so in the case of SMS phishing, the Trojan harvests the data areas of the cellphone and transmits them to the person who created the Trojan at the earliest opportunity. It is a way of performing identity theft, as the inadvertently downloaded malware captures and transmits all of the stored cellphone data, including stored credit card details, names, addresses and other data, like password details for email accounts, which, when opened, increase the vulnerability of online banking and other accounts. The malware can then cover its tracks by wiping the phone clean, including all call records, causing repeated rebooting or similar odd behavior rendering the […]

What Is Cryptography In Cyber Security

Definition Cryptography is a method of protecting information and communications through the use of codes, so that only those for whom the information is intended can read and process it. The prefix “crypt-” means “hidden” or “vault” — and the suffix “-graphy” stands for “writing.” In computer science, cryptography refers to secure information and communication techniques derived from mathematical concepts and a set of rule-based calculations called algorithms, to transform messages in ways that are hard to decipher. These deterministic algorithms are used for cryptographic key generation, digital signing, verification to protect data privacy, web browsing on the internet, and confidential communications such as credit card transactions and email. Cryptography provides for secure communication in the presence of malicious third-parties—known as adversaries. Encryption uses an algorithm and a key to transform an input (i.e., plaintext) into an encrypted output (i.e., ciphertext). A given algorithm will always transform the same plaintext into the same ciphertext if the same key is used. […]

What Is Web Application Security?

Web application security is the process of protecting websites and online services against different security threats that exploit vulnerabilities in an application’s code. Common targets for web application attacks are content management systems (e.g., WordPress), database administration tools (e.g., phpMyAdmin) and SaaS applications. Perpetrators consider web applications high-priority targets due to: The inherent complexity of their source code, which increases the likelihood of unattended vulnerabilities and malicious code manipulation. High value rewards, including sensitive private data collected from successful source code manipulation.

Quantum computing is a branch of computer science that is based on the principles of the superposition of matter and quantum entanglement and uses a different computation method from the traditional one. In theory, it would be able to store many more states per unit of information and operate with much more efficient algorithms at the numerical level, such as Shor’s or quantum annealing. This new generation of supercomputers uses knowledge of quantum mechanics — the area of physics that studies atomic and subatomic particles — to overcome the limitations of classic computing. Although in practice, quantum computing faces evident problems regarding scalability and incoherence, it makes it possible to perform multiple simultaneous operations and eliminates the tunnel effect that limits current nanometric scale programming. Quantum computers are machines that use the properties of quantum physics to store data and perform computations. This can be extremely advantageous for certain tasks where they could vastly outperform even our best supercomputers. USES […]

what is computer programming?

Computer programming by definition is the art of issuing commands and giving computers instructions about what they should do next. These instructions are known as code, and computer programmers write code to solve problems or perform a task. The end goal is to create something: that could mean anything from a web page, or a piece of software, or even just a pretty picture. That’s why computer programming is often described as a mix between art and science; it’s technical and analytical, yet creative at the same time. When I first started looking for courses to teach myself how to code, I realized just how much I didn’t know. My brothers work as programmers, so I’d seen the lines and lines of symbols and letters they wrote, but I had no idea what they all meant. I didn’t even know how what I saw on my screen when I was carrying out simple tasks such as shopping online or browsing […]

Computer networking is an engineering discipline that aims to study and analyze the communication process among various computing devices or computer systems that are linked, or networked, together to exchange information and share resources. Computer networking depends on the theoretical application and practical implementation of fields like computer engineering, computer sciences, information technology and telecommunication. A router, network card and protocols are the essential pillars upon which any network is built. Computer networks are the backbone of modern-day communication. Even public switched telephone networks are controlled by computer systems; most telephonic services are also working with IP. The increasing scope of communication has led to much advancement in the networking field and in its relative industries like hardware, software manufacturing and integration. As a result, most households have access to one or more networks. There are three broad network types: Local Area Network (LAN): Used to serve a small number of people located in a small geographical space. Peer-to-peer or […]

The second type plays dead until the trigger kick starts the malicious code. In other words, the infected program needs to run to be executed. Therefore, it is highly significant to stay shielded by installing a robust antivirus program. ORIGIN OF COMPUTER VIRUS An engineer called Robert Thomas, At BBN Technologies developed the first known computer virus in the year 1971. The first virus was christened as the “Creeper” virus, and the experimental program carried out by Thomas infected mainframes on ARPANET.

Definition Cloud computing is the delivery of on-demand computing services — from applications to storage and processing power — typically over the internet and on a pay-as-you-go basis. Simply put, cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale. You typically pay only for cloud services you use, helping lower your operating costs, run your infrastructure more efficiently and scale as your business needs change. History of cloud computing? Cloud computing as a term has been around since the early 2000s, but the concept of computing-as-a-service has been around for much, much longer — as far back as the 1960s, when computer bureaus would allow companies to rent time on a mainframe, rather than have to buy one themselves. These ‘time-sharing’ services were largely overtaken by the rise of the PC which made owning a computer much more affordable, […]
