Application Security Since apps on your computer are a soft target for attackers, you can protect them with application security. It adds security features to the apps to keep them safe from cyber-attacks. Web application firewalls, antivirus software, firewalls, passwords, and encryption are a few examples of application security systems. Information Security If you are worried about the unauthorized use of your computer system or breach of its confidentiality, availability, and integrity, you may employ information security. This type of computer security focuses on protecting information through the CIA triad model that makes sure that data remains secure at all times without loss of productivity. Network Security Cybercriminals are often on the lookout for loopholes in the network to invade your computer. Therefore, you must have a network security mechanism in place to prevent unauthorized access to your computer networks. Endpoint Security The responsibility of protection from computer threats always rests with the end-user. However, many times, users unintentionally help attackers fulfill their unlawful purposes (for example, users often click on malicious links unknowingly). Therefore, endpoint security aims to create awareness among users about computer security topics, such as phishing/social engineering attacks, creation and usage of passwords, device/physical security, and the importance of cybersecurity. Internet Security As you may already know, the internet is a virtual door to a lot of things, such as information and computer safety risks (like viruses, spyware, and other malware). Therefore, internet security means protecting the computer from various internet-based issues. Above, we have discussed computer security’s definition and its types to give you a basic idea of the topic. Now, in our view, you are well prepared to combat the following personal computer threats that you may encounter. Most Common Computer Security Threats Now, it’s time to know the computer security risks that may come your way. We share them below. 1. Phishing Image Source: IronNet Phishing attacks are common and one of the most potential threats to computer security. According to recent research, over 81% of organizations fell prey to phishing in the past year. Most commonly, phishing attacks occur through emails. The attacker uses a familiar-looking email address to trick you. If you click on the mail, open the given attachment, and fill in the required information, you end up losing your data. Moreover, users even reported financial losses due to computer security threats like phishing. Apart from emails, hackers have also started phishing through the cloud applications of companies. Therefore, you should take appropriate steps to protect them. 2. Malware If you get an error message “Serious security threats have been detected on your computer”, your device might be malware-infected. Malware is malicious software, like spyware, ransomware, viruses, etc. Malware attacks happen when you click on any infectious link or email attachment. Once inside your computer, malware can cause a lot of damage, such as the installation of harmful software, preventing access to the network’s key components, gathering your private information, and more. Note: According to a recent study, ransomware attacks saw an increase of over 140% in 2021’s third quarter alone. Going by the numbers, you can estimate that there might be an exponential increase in malware attacks in 2022. Also Read: Best Free Malware Removal Tools for Windows 3. Man in the Middle MitM or Man in the Middle is one of the types of computer threats where the hacker places himself between a two-party transaction. Once the cybercriminal enters the communication, he may steal sensitive data. Man in the Middle attacks mostly occurs through unsecured public WiFi networks. Hence, you must use them cautiously. 4. Denial of service Another threat to computer cyber security is the denial of service attacks. These kinds of attacks prevent you from accessing the machine or network resources. It floods the system, network, or servers with useless data and requests to make them inaccessible. Moreover, through distributed denial of service, attackers can even attack your device using many infected devices. Note: According to the recent figures, denial of service attacks cost over $20000-$40000 per hour to a company. That’s quite a huge amount! 5. SQL Injection The next computer security risk you may face is SQL injection. Here, cybercriminals insert malicious code into SQL servers to access the database. After accessing the server, the attacker can view the data, change, or delete it. 6. Emotet Let’s now talk about Emotet. It is a Trojan (type of malware) that enters your computer to steal your sensitive or confidential information. Emotet makes its way to your computer through spam emails, malicious scripts, or infected links. It is regarded as one of the most expensive and harmful malware. Note: Emotet does not stay on a single computer. It replicates itself like a worm and spreads the infection to all connected computers. According to recent statistics, Emotet has already affected more than 5% of organizations across the globe. 7. Social engineering attacks Perhaps the most common form of protection from unauthorized use of a computer system is the password. However, with the rise of social engineering attacks, even passwords are at risk. Hackers use social engineering or a strategy involving human interactions to trick users into revealing their passwords. Moreover, other forms of social engineering attacks include accessing the security keys (passwords) through guessing or a password database. Note: According to recent research, social engineering attacks increased by an alarming rate of 270% in the year 2021 and are expected to rise even more in 2022.

Almost all programs have certain vulnerabilities that may pave the way for hackers to invade your system. Zero-day exploits happen when these loopholes become known to notorious minds before the software/app developers release a patch update to fix them. Note: As witnessed by researchers, zero-day exploits increased dramatically by 100% from the year 2020 to 2021. These attacks are on a rise in 2022 as well. 9. Advanced persistent attacks When a malicious actor enters a network or system and remains undetected for a significant period, we call it an advanced persistent attack. Here, the attacker aims to keep a check on your network activity to gain crucial information about the target. The target of advanced persistent attacks is mostly esteemed enterprises, national sites, and other high-value victims. Note: Various researches predicted that in 2022 mobile devices, supply chains, and cloud computing software will be among the top victims of advanced persistent attacks. 10. IoT attacks In the modern world, IoT (Internet of Things) has gained immense popularity. Cybercriminals attack IoT devices through botnets. The botnet malware looks for unguarded devices on the internet and infects as many devices as it can. The botnet uses the power and resources of the infected devices for various automatic activities that are unknown to the device user. Moreover, hackers employ these botnets to execute email spamming, fraudulent campaigns, malicious traffic generation, and other unlawful activities. Note: As reported by Gartner, over 25% of cyberattacks will relate to IoT in the time to come. After learning about the most common computer security threats, you might be wondering how to protect your device from them, right? Well, we share the same in the next section. How to Protect the Computer from Security Threats You can follow some simple tips to safeguard your computer and data. They are given below. Use strong passwords Passwords are the most common tool to protect your computer and data from unauthorized access. You must keep a password that is hard enough to guess. You may use a combination of numbers, letters, and symbols to create such a password. Install an antivirus software Antivirus software is the protective shield you need to safeguard your data from the prying eyes of hackers. It helps keep away viruses and other malware. It also lets you detect and remove viruses with ease if ever your device gets infected. If you are confused about which antivirus to use, you may pick one of our top recommendations. Update your operating system, applications, and browser Updates patch the security loopholes that hackers may exploit for their unlawful purposes. Moreover, the first rule of computer security is to check patches. Hence, we always advise our readers to keep their OS, Web browser, and applications up-to-date at all times. Ignore suspicious looking emails Hackers often use lucrative emails to deceive the target. Thus, if an email looks too good to be true, never click on it. For example, if you get an email that says you won a one million dollars lottery, that’s most likely a scam designed to rob you. Hence, resist the temptation to claim the reward. Employ two-factor authentication Passwords are the most common method of authentication. However, as hackers have now become intelligent enough to crack weak passwords, many websites provide an option of two-factor authentication. Here, you get access after entering your password and another form of verification, such as an OTP (One Time Password) received on your email/mobile number. We find it better to keep the two-factor authentication and recommend doing the same to our readers. Above, were the security threats to your computer and ways to keep them at bay. If you still have any questions or confusion, you can go through the next section to find the needed answers.
