Clearly, the first half of 2020 was quite challenging for organizations in terms of cybersecurity along with the adoption of new normal changes. Besides, we are still unsure of what cybercriminals have in store for the next six months of 2020. 

Although, by learning lessons from the recent data breaches, we can secure our organizations from emerging cyber threats. Here are some of the “must follow” security measures for your organization to stay secured in these unsecured times: 

  1. Educate your employees with security awareness training to help them in recognizing and combating emerging cyber threats.
  2. Incorporate phishing incident response tool to instantly report suspicious-looking and unsolicited emails.
  3. Secure your email domains against email spoofing attacks by implementing email authentication protocols such as DMARC, SPF, and DKIM.
  4. Keep all your software and applications updated with the latest security patches from time to time.
  5. Use a VPN connection for a protected network to keep hackers and other threat actors at bay while working remotely.
