What are Cyber threats?
Cyber threats or cyber security threats are actions that pose harm to digital systems. These actions seek to destroy, steal or weaken digital life in general.
Some of these threats include:
• Ransomware is a type of malware that encrypts the data of the victim, rendering them inaccessible, until a ransom is paid (mostly in cryptocurrency) before access is granted.
• SQL injection (SQLi) is a malware that allows cybercriminals to use a malicious SQL code to access and modify private information of the victim.
• Man in the middle is a type of attack where a person secretly eavesdrops and intercepts a conversation between two parties.The attacker monitors and can perhaps change the messages.
• Phishing is a type of attack that aims to deceive the victim by pretending to be a trusted person or family member. We have email phishing, voice phishing, amongst others.
• Denial of Service is a cyber threat that aims to shut down a system, network or machine and prevent access to it.
While there are many types and kinds of cyber threats, the most common ones have been explained above.
Protecting your device against Cyber threats.
These are very useful tips to keep your device protected from the different kinds of cyber threats.
1. Always keep your software and systems updated: Updates often include patches and security fixes that address vulnerabilities, reducing the risk of exploitation by hackers. Regularly installing updates helps maintain the integrity and safety of your system.
2. Make use of Multi-Factor Authentication (MFA): This provides an additional safeguard which helps protect against unauthorized access, adding an extra layer of verification beyond just passwords. It is especially effective in enhancing security for sensitive accounts, including those involving payments and financial transactions.
3. Check the strength of your passwords: Using complex and unique passwords is essential for enhancing security. A combination of numbers, uppercase and lowercase letters, and symbols makes it more challenging for unauthorized individuals to guess or crack your passwords. Avoiding password reuse is also crucial, as it prevents potential compromises if one account is compromised.
4. Be cautious of random emails and links: Avoid clicking on links or opening attachments in such emails to prevent potential phishing attacks or the spread of malware. Verify the sender's identity before interacting with any unfamiliar emails to enhance your online security.
5. Antivirus software is also important in keeping your device safe: Antivirus programs like Malwarebytes and Avast help protect your system by detecting and preventing malicious code or software that could potentially harm your computer. They play a crucial role in safeguarding against various cyber threats.
6. Use a firewall: A firewall is a security device that helps to monitor traffic in one's network. It prevents unauthorized access into the computer network and blocks potential attacks before they can cause harm. It's a crucial component in the overall security strategy for protecting your network and systems.
7. Enable data encryption if not already enabled: Data encryption is a key tool for maintaining the privacy and security of sensitive information, including data and photos. It transforms the data into a coded format that can only be deciphered with the correct encryption key. This adds an extra layer of protection, making it harder for unauthorized individuals to access or understand the encrypted content.
8. Make sure stolen devices can be traced, secured or erased: To do this, ensure it has tracking features activated like, Find My Device (Android) or Find My iPhone (iOS). Regularly back up data to easily restore or remotely wipe if needed.
In conclusion, cyber threats are prevalent in cyberspace, so it is paramount that we keep our devices protected to prevent them from being attacked.
