What Are the Common Cybersecurity Threats?

Cybersecurity threats can harm your devices, or steal personal information, or block access to your data, or even syphon off money from your bank account. Following are the common cybersecurity threats:

Malware

Malware, or malicious software, is like a digital virus that sneaks into your device if you click an infected link or download something that is unsafe. Once the virus enters your device, it can cause havoc, like gaining access to your photos, bank details, passwords, etc. Some malware spreads from file to file, while some like spyware secretly watches what you do online.

Ransomware

Ransomware or digital kidnapping is where your files get locked and you are asked to pay an amount (ransom) to retrieve the files.

Phishing

Scammers send emails, texts, or messages to potential victims claiming to be from legitimate sources. You may click on it, thinking it is from your bank or credit card company, and enter your details. The moment you enter your personal details, they are used to access your accounts secretly. Without the victim’s knowledge, their bank accounts are emptied.

Denial-of-Service (DoS or DDoS)

In a DoS, a website of a bank, online store, or government is flooded with too much traffic, making it slow or unavailable. It may sometimes cause the site to crash completely.

Man-in-the-Middle (MitM)

In this type of threat, a hacker may secretly get between you and the site you are using and steal your login details or password.

Cryptojacking

Cryptojacking is when hackers secretly steal your device’s power to mine cryptocurrency, that means validating transactions on a blockchain. They don’t steal your data, but your device battery is used, causing it to slow down.

Spoofing

Spoofing is when hackers pretend to be someone you trust. You may receive a phone call claiming that he is your bank’s customer care executive. You might be asked to reveal OTP or password. When you do that, your account is accessed fraudulently and your bank account money may be stolen.

Password Attacks

Hackers may use keyloggers, malware that records every key you press. It helps them to guess weak passwords and access your accounts.

IoT Attacks

Did you know that smart devices like cameras, doorbells, and thermostats can be hacked if they are not secured properly? Since many of these devices have weak passwords or outdated software, they can be hacked. Such devices can be used to spy on you.

What Are the Types of Cybersecurity?

Various types of cybersecurity work together to protect digital systems, data, and networks from cyber threats.

Network Security

Network security protects computer networks from unauthorised access. It uses tools like firewalls that block suspicious traffic and keep data safe.

Application Security

Application security keeps software and apps safe from threats. Developers build security into apps from the start and regularly release updates to fix weaknesses.

Information and Data Security

This ensures that sensitive data is kept private and made available only when needed. Techniques like access controls decide who should be given access so that only authorised people can view or access the data.

Cloud Security

As more data and services move to the cloud (like Google Drive or Microsoft Azure), cloud security is important. But both are responsible: the cloud provider by securing the cloud infrastructure and users by safeguarding their data credentials.

Endpoint Security

This protects individual devices like computers, smartphones, and tablets that connect to a network. Example, antivirus software protects your device since these devices can be entry points for hackers.

IoT and Operational Security

Internet of Things (IoT) security deals with protecting smart devices that connect to the internet. Critical infrastructure security protects systems like power grids and transportation networks from cyberattacks that could disrupt public services.

Best Practices to Follow to Avoid Being a Victim of Cybersecurity Threat

There are some simple things you can do to keep your devices safe and avoid being a victim of a cybersecurity threat:

Be Careful With Links and Emails

Always check who the sender is before opening your messages or emails. If you are doubtful, do not open the link provided in the mail; rather, visit the official website directly.

Do Not Be Reckless With Passwords

Your passwords should be strong enough to prevent others from guessing them. Do not use the same password for multiple websites and do not rely on your password solely for accessing your account. Enable two-factor authentication to strengthen your fight against hackers.

Keep Software Updated

Make sure your phone, computer, apps, and operating system are always up to date so that any weakness can be fixed with the help of security patches.

Using Secure Networks

Protect your home Wi-Fi network with a strong password and avoid using public networks. Also, whenever you enter personal information on a website, check if the web address starts with “https://” and has a padlock icon in the address bar.

Don’t Overshare on Social Media

Do not post too much on social media, like your full birthdate or home address, because it can help scammers guess your passwords.

Turn Off Bluetooth When You Are Not Using It

Hackers can sometimes access your phone or laptop through Bluetooth if it’s left on and discoverable.

Never Leave Your Devices Unattended

Always lock your phone, tablet, or laptop when it is idle and you are not using it.
