Protecting Your Digital Assets: 10 Cybersecurity Threats You Need to Know About in 2021
As we continue to rely more on technology, the risk of cyber attacks and data breaches increases. Cybercriminals are constantly evolving their tactics and techniques to exploit vulnerabilities in our systems. Here are 10 cybersecurity threats you need to know about in 2021 to protect your digital assets.
1. Phishing Attacks
Phishing attacks are one of the most common threats to cybersecurity. They involve tricking people into clicking on links or downloading attachments that contain malware. Phishing emails may appear to be from a trusted source, such as a bank or a social media platform, and can be difficult to identify. In fact, 32% of data breaches involve phishing attacks. To protect yourself, be cautious of any unexpected emails and avoid clicking on links or downloading attachments from unknown sources.
2. Ransomware
Ransomware is a type of malware that prevents users from accessing their systems or data. Cybercriminals will demand a ransom payment in exchange for restoring access. Ransomware attacks have increased by 350% since 2018, and the average ransom payment is now over $100,000. To prevent ransomware attacks, regularly backup your data and keep your systems up to date with the latest security patches.
3. Malware
Malware is a broad category of malicious software that includes viruses, spyware, and trojans. Malware can be used to steal sensitive data, damage systems, or gain unauthorized access to networks. In 2020, the global cost of malware attacks was estimated to be $11.5 billion. To prevent malware attacks, use anti-virus software and keep your systems up to date with the latest security patches.
4. DDoS Attacks
A DDoS (Distributed Denial of Service) attack involves flooding a network with traffic to overwhelm and shut down the system. This can be used to disrupt websites or online services. DDoS attacks have become more frequent and more powerful in recent years. In fact, the largest DDoS attack on record peaked at 2.3 terabits per second. To prevent DDoS attacks, use a DDoS mitigation service and regularly test your systems for vulnerabilities.
5. Insider Threats
Insider threats involve employees, contractors, or partners who have authorized access to systems but misuse that access for malicious purposes. Insider threats can be intentional or unintentional, and can cause significant damage to organizations. According to a recent study, 60% of organizations have experienced an insider attack in the past year. To prevent insider threats, implement access controls, monitor user activity, and educate employees on cybersecurity best practices.
6. Zero-Day Exploits
Zero-day exploits are vulnerabilities in software that are unknown to the vendor and can be exploited by cybercriminals. Zero-day exploits can be used to gain unauthorized access to systems or steal sensitive data. In 2020, there were over 1,400 new zero-day vulnerabilities discovered. To prevent zero-day exploits, keep your software up to date with the latest security patches and use intrusion prevention systems.
7. Social Engineering
Social engineering involves manipulating people into divulging sensitive information or performing actions that can compromise security. Social engineering attacks can be conducted through phone calls, emails, or in-person interactions. This type of attack has become increasingly common, with 43% of data breaches involving social engineering in some form. To prevent social engineering attacks, educate employees on how to identify and report suspicious activity.
8. IoT Vulnerabilities
The Internet of Things (IoT) refers to the network of devices that are connected to the internet, such as smart home devices and medical equipment. IoT devices can be vulnerable to cyber attacks, as many lack basic security features. In fact, 98% of IoT traffic is unencrypted, making it easy for cybercriminals to intercept data. To protect your IoT devices, change default passwords, keep software up to date, and use a separate network for IoT devices.
9. Cloud Security
More organizations are moving their data and applications to the cloud, but this can create new security risks. Cloud providers may not be responsible for securing all aspects of their customers' data, and misconfiguration or human error can lead to data breaches. In fact, 80% of cloud breaches are caused by misconfiguration. To protect your cloud data, use strong access controls, encrypt data, and regularly audit your cloud environment.
10. Supply Chain Attacks
Supply chain attacks involve exploiting vulnerabilities in a company's supply chain to gain access to their systems or data. This can involve compromising a vendor or partner that has access to the target's network. Supply chain attacks have become more common in recent years, with high-profile attacks on SolarWinds and Microsoft. To prevent supply chain attacks, implement strong vendor security requirements, monitor vendor activity, and regularly test your systems for vulnerabilities.
Conclusion
As technology continues to advance, cybersecurity threats will continue to evolve. It is important to stay informed about the latest threats and take proactive steps to protect your digital assets. By implementing strong security measures and educating yourself and your employees on best practices, you can reduce the risk of cyber attacks and minimize the impact of any breaches that do occur.
