In this digital era, our reliance on computing devices has increased exponentially. Devices like tablets and tower PCs have become an integrated part of our daily lives, providing us with convenience and efficiency to handle our daily workloads and connections. However, comfort comes at a cost – a higher risk of cyber threats.
Cyber threats range from viruses and malware to Botnet software and sophisticated hacking practices that can wreak havoc on individual users and businesses. These security threats are the masters of disguise and manipulation – they can compromise your tablet or desktop computer, logic, or data and steal, leak, or hold your complete hostage.
Undoubtedly, our tower and tablet PCs are the storehouses of our personal information, so the need to protect them from cyber threats becomes paramount. Unluckily, there is no rule of thumb to avoid the occurrence of cyber-attacks rather than staying vigilant and adopting holistic security approaches.
We’ve all heard of companies paying millions or even going out of the market because of a simple hack into their systems. So, prevention is essential; this article explores different security measures and software to fortify your tower and tablet PCs against the ever-present cyberattacks.
What is Cyber Threat, exactly?
A cyber attack is a malicious practice that can damage data, steal information, or disrupt your digital life. Cyber threats include a range of data breaches, computer viruses, denial of service, and numerous other attack vectors. This is something with the potential to cause serious harm to your stability and well-being.
Cyber threats can also be defined as an act intended to gain unauthorised access to a computer network or damage or steal an information technology asset, intellectual property, or any other form of private data.
Cyber threats can arise from numerous threat actors like trusted users within your circle or external parties from remote locations.
Types of Cyber Threats
Cybersecurity threats are not new to the world. You must be aware of and ahead of all the latest threats in the domain that can impact your tablet PCs and tower desktop computers. Here is the list of potential cyber threats that can attack your devices.
Malware is a general term that refers to any software or file meant to disrupt or harm your computing device. Malicious software acquires unauthorised network access by exploiting vulnerabilities, usually when a user clicks on an email attachment or a malicious link. This might install potentially hazardous software on your device. The following are the types of malware:
Viruses are types of malicious code that install itself on a computer without the user’s knowledge. These viruses can replicate and spread to other files by attaching to computer files. Worms, conversely, are self-replicating like viruses are, but they do not require a connection to another program to reproduce.
Trojan is a form of malicious software that identifies itself as liable, but when you install it can harm your system.
Ransome is one of the leading cyber attacks. It is a type of malware that can steal your information and demand payment for the decryption key. Even if you decide to pay the ransom, there is no guarantee that your encrypted data will be successfully recovered.
Hackers can use this practice to monitor your computing activity and harvest your private information illegally.
Botnet software is specially designed to impact a vast range of devices sharing the same Internet connection. The botnet software combined millions of machines with a single negligible amount of processing power. It may be very challenging to detect the botnets.
- Remote-access Trojans or RATs
Remote-access Trojans or RATs are the most dangerous form of malware in which backdoors are installed on the targeted devices. These backdoors provide remote access and administrative control to the hackers.
- Zero-Day Exploits
These attacks use software or hardware vulnerabilities that developers have not identified or patched.
- IoT Vulnerabilities
Smart gadgets linked to the same network as your PCs can serve as entry points for cyberattacks if not appropriately secured in these cyber-attacks.
- Supply Chain Attacks
Cybercriminals infiltrate the hardware or software supply chain, inserting malware or exploiting vulnerabilities before they reach end users.
- Credential Theft
Hackers and other malicious users can steal login credentials through keyloggers or phishing to gain unauthorised access.
- Drive-By Downloads
In these attacks, infected code is automatically installed and executed when you visit compromised websites and click on malicious links.
In these attacks, people might use their desktop PC’s processing power to mine cryptocurrency without authorisation. It can cause performance lags in your system.
- Wi-Fi Eavesdropping
Cyber attackers intercept data transmitted over unsecured Wi-Fi networks, potentially harming your data.
- Domain name system (DNS)
These poisoning attacks compromise the DNS to redirect your web traffic to malicious sites without hacking the affected sites.
- Distributed Denial-of-service or DDoS
The DDoS disrupts a device’s network by flooding the network with excessive requests from a botnet to prevent legitimate requests.
The Best Hardware Security Measures
To ensure the security of your desktop tower PCs, tablets, and other devices, you must begin by implementing robust physical and hardware security measures. These measures act as the first layer of protection against potential cyber threats. Here are the list of essential hardware security measures you should consider:
Use Strong Passwords
Passwords are the primary type of device security. Some websites have a minimum password complexity. For example, you must put a particular mix of character types to make your account. You must avoid repeating the passwords and try changing them regularly. Refrain from using easily guessable information such as your name, school, birthdate, or common words.
You can also employ a password management application to save and lock your passwords. These applications keep track of your passwords and create randomised strong passwords that are almost impossible to access and guess by hackers and other unauthorised sources.
Use 2-factor authentication (2FA)
2-factor authentication (2FA) is another convenient method to protect your online accounts. It adds a layer of security to your accounts by asking for two ways of proving your identity. One common form of two-factor authentication is the password; you’ll receive a text code or message via your phone number or email to confirm your identity.
With two-factor authentication (2FA), attackers will find it much more difficult to mimic and steal your personal information. This additional protective layer reduces identity theft risk, which can cause significant financial and personal harm.
Make Secure Boot Processes
Secure Boot, also known as UEFI Secure Boot, is a security feature designed into the firmware of the latest tablets and tower PCs that replaces the legacy BIOS (Basic Input/Output System).
It can prevent unsigned or malicious bootloaders, device drivers, and operating system components from loading during system startup. TPM hardware module provides cryptographic functionality for the secure storage of encryption keys, improving data security. You can use it effectively to protect your devices and data.
Use Hardware Firewalls
A hardware firewall is a physical device like a server that filters the traffic to your device. A user plugs a network cable directly into a computer or server. However, with a hardware firewall, the cable is plugged into the firewall first. UTM devices are standard hardware firewalls that combine firewall, antivirus, and other security features into a single package for comprehensive protection.
Get the Most Out of Biometric Security
Biometric security includes using biometric information for identification, access control, and authentication. You must enable biometric authentication on your devices. These security features collect biometric data, which is scanned and algorithmically compared to information previously stored in the database.
The Best Software Security Measures
Protection of your computing devices extends beyond just hardware. You can also implement strong software security measures to fortify your tablet PCs and the best computer tower against various malware, cyberattacks, and vulnerabilities. Here are essential software security measures you can perform:
Keep Your Software Up to Date
One of the easiest ways for your system to protect against viruses and vulnerabilities is to keep the software up to date. Software updates come with security patches and bug fixes that fix the risks of hacker attacks.
You must regularly update your operating system, web browser, and other application software. You can set your PC to update itself automatically when new updates come onto the market, so you don’t have to install them individually.
Use a Secure Web Browser
Outdated web browsers installed on the devices may not have secure default settings. You must use the latest and updated browsers with pre-installed security features to block infected websites and prevent malicious code from installing on your tower desktop computer.
Also, you should only visit trusted platforms and websites and download software from familiar sources. These sites often host malware download or encrypt your device.
Use a Software Firewall
As discussed earlier, a firewall is a security component that protects your PC’s hardware or software by blocking outsiders from gaining unauthorised access and filtering traffic. So, like a hardware firewall, you need to install a software firewall on your system to stop malicious software from infecting your desktop PC.
The firewall acts as a gatekeeper, monitoring attempts to access your operating system and blocking unwanted traffic or brute force attacks.
Install Antivirus Software
Antivirus software protects your computer against viruses, malware, and other internet threats. This software analyses your desktop computer or tablet PCs or detects harmful files, and can prevent them from entering your system. To ensure continual protection, choose a reputable antivirus software provider and keep it up to date occasionally.
Download Anti-malware Software
Anti-malware software is another type of computer software tailored to prevent malware attacks. This software scans your tablet PCs or tower desktops for malware and removes it if found.
It also safeguards your device from malware infections by precisely monitoring it for suspicious activity. Different types of paid and unpaid anti-malware software are available in the market. These include Norton Antivirus, McAfee Antivirus, Kaspersky Antivirus, and Avast Antivirus.
Backup Data Regularly
Backing up all of your data adds redundancy and guarantees that critical information stays secure and undamaged, even in the case of a security compromise. Injections and ransomware might jeopardise the integrity and accessibility of your data.
You can use backup software to schedule many backups a day or week, depending upon the number of tasks you perform on your device. During the backup process, include all the gadgets and software in your backup perimeter and make at least two copies of them.
Save one copy on an external hard drive such as a hard disk, USB key, or NAS. Another copy should be saved in the cloud storage platform, such as Mailfence documents.
Be careful About What Links or Attachments You Click on
You should be aware of suspicious hyperlinks or emails containing attachments. Cybercriminals often send emails with malicious links that can steal your vital information. The attachment is corrupted, and any hyperlink will be a website masquerading as something legitimate.
Cyber attackers aim to trick the recipient into downloading an attachment (which could expose their tablet computer to malware), clicking on a link that leads to a potentially infected website, or disclosing sensitive information like credit card details. Or may demand money in return for that might demand in return of that.
The Best Network Security Measures
Network security is the process of protecting data and information, allowing reliable access and super-tunned network performance. A well-designed network security safeguards your devices from a data breach and ensures legitimate access to websites and applications. Below are the few steps you can take to protect your network:
WI-FI Network Security
You can enable WPA3 or WPA2 encryption for Wi-Fi networks to protect your tablet’s or tower PC’s data in transit. You should update default SSIDs to unique, non-identifiable names to prevent easy identification. In addition, users may also disable Wi-Fi Protected Setup (WPS) as it can be vulnerable to cyber threats.
Remote Access VPN
You can employ a remote access VPN for sheltered and secure access to other telecommuters, mobile users, and extranet consumers. Each host typically installs VPN client software or employs a web-based client. Multi-factor authentication, endpoint compliance scanning, and encryption of all transferred data safeguard the privacy and integrity of critical information.
Cloud Network Security
Protecting modern data demands greater flexibility and innovation to keep pace with migrating application workloads to the cloud. You can use Software-defined Networking (SDN) and Software-defined Wide Area Network (SD-WAN) solutions to enable network security in public, private, and hybrid cloud-hosted Firewall-as-a-Service (FWaaS) activities.
Protecting your computing devices like tablet PCs or tower computers from cyber threats is necessary in today’s digital age. These cyber vulnerabilities pose a significant risk to your personal information and can damage your devices.
