Top 5 Cyber Security Threats of 2021 and How to Protect Against Them
As our world is becoming increasingly digitized and connected, cyber threats have become a prevalent concern for businesses and individuals alike. Cyber attacks can result in a significant financial, reputational, and operational damage, which is why understanding top cyber threats should be a top priority. Here are the top 5 cyber security threats of 2021 and how you can protect against them.
1. Ransomware
Ransomware is one of the most dangerous cyber threats that companies are currently facing. Ransomware or malware that encrypts or locks data until a ransom is paid. In 2021, we have seen a significant increase in the number of ransomware attacks, and sophisticated criminals continue to use it as a tool for extortion. To combat this threat, businesses should ensure that they have a robust backup system, routinely test data restoration processes and invest in strong anti-malware and anti-phishing measures.
2. Phishing attacks
Phishing attacks are a form of social engineering that tricks users into divulging sensitive information like login credentials or credit card numbers. As emails and messaging platforms are now prevalent, phishing attacks have become an increasing threat. To avoid phishing scams, users must refrain from clicking links or attachments in unfamiliar emails. Ensure that employees receive regular training on identifying and reporting phishing scams.
3. Insider Threats
Unfortunately, many of the cyber threats businesses face may come from within their organization. Insider threats are a real concern for businesses. These threats can come from employees who intentionally or accidentally compromise sensitive data. Businesses can prevent insider threats by implementing policies that limit access to sensitive data, monitor employee activity, and conduct regular security training.
4. Advanced Persistent Threats (APTs)
Advanced Persistent Threats or APTs are cyber attacks that remain undetected for an extended period. Attackers use this technique to monitor and collect sensitive data over prolonged periods. APTs are challenging to detect, so businesses must implement security measures such as multi-factor authentication, firewalls, and intrusion detection systems to protect against them.
5. Internet of Things (IoT) Hacking
As more and more devices are connected to the internet, IoT hacking has emerged as a new cyber threat. Smart home devices, wearable technology, and even cars can be hacked. To protect against IoT hacking, businesses and individuals should ensure that every device is updated to the latest software, use strong passwords, and invest in anti-malware and security software.
In conclusion, these are the top 5 cyber security threats of 2021. Prevention and mitigation of threats require a combination of proactive measures such as the ones mentioned above and an informed, security-aware user base. By taking steps to protect against these cyber threats, businesses and individuals can minimize the chances of falling victim to attacks, and keeping sensitive information safe.
