The word cyber comes from the term cybernetics, which means the study of systems, control or machines. And, we all know the meaning behind the word security: it is protection. Combining both words, we can say that cybersecurity is the process of protecting the system or machine from external malicious attacks. <\/p>\n\n\n\n
Cybersecurity<\/a> has several measures to provide security to hardware, software and data. It includes measures such as firewalls, encryption, antivirus software and multi-factor authentication(MFA). Let\u2019s see these measures in detail in the upcoming sections.<\/p>\n\n\n\n A cyber attack<\/a> is a malicious attempt to gain unauthorized access or cause damage to a system, network, software or data. The main objective of cyber attacks is to steal sensitive information, cause financial damage, and disrupt or damage the operations of an organization. According to Identity Theft Resource Center(ITRC)<\/a>, the annual breach report recorded 2,365 cyberattacks in 2023. That\u2019s approximately 6.5 attacks per day, but the number of victims is higher, over 343 million per year, i.e., 9,40,000 per day or nearly 11 per second.<\/p>\n\n\n\n There are several types of cyber attacks. Here are the most common types:<\/p>\n\n\n\n Malware is also known as Malicious Software. This software program or attack is designed to cause damage to a system. It has various types of software programs that are malicious to the system. It includes the following.<\/p>\n\n\n\n Viruses are a type of malicious software that replicates itself and spreads to all the other systems, damaging files and software.<\/p>\n\n\n\n Ransomware is a type of malware that encrypts the user\u2019s files and demands payment(ransom) to restore access.<\/p>\n\n\n\n Trojan horses are malware disguised as a legitimate program, if executed once, they will give unauthorized access to the attackers.<\/p>\n\n\n\n Let\u2019s consider a user downloading a free game from an untrustworthy website. The game may contain trojan that provides hackers access to the user\u2019s bank account when they log in.<\/p>\n\n\n\n The next type of cyber attack is phishing. It is a practice of tricking people to provide sensitive information such as usernames, passwords or credit card numbers by pretending to be a trustworthy person or a website. This attack mostly happens through fake emails, websites or social media messages that look legitimate but are designed to steal personal information.<\/p>\n\n\n\n For example, you are receiving an email from your bank asking you to verify your account information or additional documentation. The email contains a link to a fake website that is designed to steal your login information.<\/p>\n\n\n\n The next common type of cyber attack is Denial of Service (DoS) or also known as Distributed Denial of Service(DoS). This attack sends an overwhelming traffic to a target system, server or network, causing it to become slow or completely unresponsive. Distributed Denial of Service (DDoS) involves multiple computers or devices working together to launch the attack, making the user harder to defend against.<\/p>\n\n\n\n Consider you are navigating to some website or let\u2019s take google.com as an example, if it returns a 404 error or the server is busy. That is known as a denial of service attack. <\/p>\n\n\n\n SQL Injections are a type of attack that targets databases through insecure input fields on websites or web applications. By inserting malicious SQL code into a form or search box, the attacker can gain access to databases and retrieve or alter the sensitive information in the database.<\/p>\n\n\n\n For example, the attacker is inducing malicious SQL code into the login details of your banking website. Without knowing it, you may include your login credentials and that will provide hackers with unauthorized access to the bank’s database.<\/p>\n\n\n\n The next most common type of attack is password attacks. These attacks attempt to steal passwords to gain unauthorized access to the accounts or systems. There are several types of password attacks, such as brute force attack, where the attacker tries all the possible password combinations until they find the correct one and credential stuffing, where the attacker uses previously leaked usernames and passwords to gain access.<\/p>\n\n\n\n An attacker tries all the possible combinations of your mobile password until they find the correct one to gain access to your mobile.<\/p>\n\n\n\n Similar to SQL injection, in a cross-site scripting attack, the attacker injects malicious scripting code into the websites or web applications. These scripts execute in the user’s browser, stealing cookies, session data and other sensitive information stored in the browser. <\/p>\n\n\n\n Let\u2019s consider an attacker who injects malicious JavaScript code into a website\u2019s comment section. When the user clicks on a link in the comment, the script executes and steals their login credentials and forwards them to the hacker.<\/p>\n\n\n\n As we discussed earlier, attacks are happening every day all around the world. Cyber attacks such as Phishing, Spoofing, Password Attacks and XSS can have significant effects on our personal lives, privacy, professional and social lives. With the help of cybersecurity measures, we can avoid these effects in our lives. Let\u2019s see some of the impacts on our lives.<\/p>\n\n\n\n These are the areas where cyberattacks have an effect on our lives. In the next section, we will look into the importance of cybersecurity in our daily lives.<\/p>\n\n\n\n So far, we have discussed cyber attacks and how they impact our lives. Now, we will look into the measures that the cybersecurity field uses to secure our lives and how it is important.<\/p>\n\n\n\n Cybersecurity measures are the technologies and practices that are designed to protect computer systems from malicious attacks. In this increasingly digital world, personal financial and professional data are stored and transmitted electronically. To safeguard this information, cybersecurity measures play a major role. Below are some of the key cybersecurity measures and their importance to our daily lives.<\/p>\n\n\n\n A firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between trusted networks and untrusted external networks.<\/p>\n\n\n\n Firewalls play an important role in preventing unauthorized access to your device or network. For example, when you connect your computer to the internet, a firewall ensures that only trusted traffic passes through and blocks malicious attempts. Without a firewall, your system would be more vulnerable to cyberattacks.<\/p>\n\n\n\n The next most common cybersecurity measure is encryption. Encryption is the process of converting the data into a hash code to prevent unauthorized access. Only authorized users with the correct decryption key can access the original data.<\/p>\n\n\n\n Encryption protects sensitive information such as passwords and personal communications by making it unreadable to unauthorized users. Without encryption methods, the passwords can be easily breached and misused.<\/p>\n\n\n\n Next up is multi-factor authentication. It is a security mechanism that requires users to provide two or more forms of verification before they can access an account. This includes a password, a phone or security token or a biometric identification.<\/p>\n\n\n\n MFA provides an additional security layer that makes it much harder for attackers to gain access. Even if someone steals your password, they would also need access to your second factor to log in. This method is crucial for protecting your sensitive bank accounts, emails, and social media accounts.<\/p>\n\n\n\n From the name itself, we can predict what this software will do. Anti-virus software is designed to detect, block and remove malicious software such as viruses, worms, trojans and spyware from your system.<\/p>\n\n\n\n Anti-virus tools prevent malicious programs that have the potential to infect your system for steal your data or cause damage to your files. Regularly updating and executing the antivirus software reduces the risk of infection and data breaches.<\/p>\n\n\n\n The last important cybersecurity measure is the Intrusion Detection System. It monitors the network traffic for signs of malicious activity or policy violations. If it detects any suspicious activity, it alerts the system admin.<\/p>\n\n\n\n It helps detect potential cyber attacks in real-time, enabling rapid responses to threats before they cause serious damage. It is important for organizations that store sensitive data or have large networks that provide quick identification.<\/p>\n\n\n\nWhat are Cyber Attacks?<\/strong><\/h2>\n\n\n\n
