Today, as technology advances, the sophistication of cyber-attacks also increases rapidly. BEC attacks, phishing occur frequently and bring greater damage to businesses. Therefore, equipping a secure email system is essential for all businesses. Every user is at risk of becoming the target of scammers from employees to company directors. An effective email security solution must stay ahead of attacks and provide timely warnings to users. Artificial Intelligence (AI) technology has been applied in network security and is gradually becoming the trend of email security.
Email is the most preferred method of formal communication. According to Statista, 306.4 billion emails were sent and received every day in 2020. Based on the current growth rate, it is estimated that by 2025, it will be 376.4 billion emails per day. With this growing trend, businesses need to start adopting more innovative ways to combat these threat actors.
Artificial Intelligence and email security
Using Artificial Intelligence to secure email is not a thing anymore. Some businesses are using AI to read emails and detect fraudulent activities. Anti-phishing and email security services deploy AI and ML in tandem to combat the threat in the following ways:
Remember past attack trends
Attack methods of cybercriminals are increasingly evolving with the aim of bypassing the security systems used by businesses. However, sometimes they also use old techniques and methods to sneak into the system. AI technology is being used to identify such intrusion methods and perform defense exercises to fend off attacks. This is also where Big Data comes in handy. The AI-driven Big Data engine will filter through tons of data to pinpoint the exact attacker to the system.
Machine learning
One of the key points of Machine Learning (ML) is to train them to work independently and identify threats on their own. And that is done through the use of Artificial Intelligence. AI-powered Machine Learning tools can sift through thousands of emails to determine the cause of the disruption. Then the system will proceed to remove those dangerous agents.
Data saving
AI can memorize suspicious emails. When similar emails are encountered, they will be moved to the trash folder for later deletion. This method is a giant leap over previous ways of working. However, this approach is still reactive and not defensive. The system needs to identify the incoming threat and neutralize it immediately.
With Covid-19 raging around the world, scammers took advantage of it by purchasing 130,000 pandemic-related domains. Attackers used these domains to send emails to individuals seeking grants, financial information, and vaccine registrations. These fake links will send victims to fake websites and record their financial information. This information will then be used to impersonate and extract funds from the accounts. But fortunately, Artificial Intelligence technology now has some solutions against such emails.
The improved threat detection engine
With the current increase in cybercrime, the traditional security tools themselves have been radically improved. Anti-ransomware software using AI technology has helped organizations feel somewhat more secure. Most organizations today are using new technologies like AI and ML, to scan and identify potential threats. It helps IT, staff, enterprise security teams prevent damage in the long run.
Detect and warn before being attacked
Most traditional security tools only react after the attack has been performed. The phishing email has now been sent to the user’s inbox and is waiting to be opened. After that, the system will only notice which links inside it are fake and advise users to be careful. But today, 4.0 technology will be one step ahead of that. The system will build barriers to prevent these emails from reaching users. It is done by extrapolating different data points, which come from the emails received by the user. The AI will then analyze these email samples and draw conclusions. This helps the software understand what kind of secure email an individual usually receives. When the system remembers these characteristics, any suspicious details will be considered an indication of an attack.
The development direction of Artificial Intelligence in the field of Secure Email
Artificial Intelligence can be used to solve many problems, email protection being one of them. It can be seen that although the Internet is increasingly advanced, email is still trusted by individuals and businesses. Over the past 40 years, the format and usage of email have remained the same. However, sending and receiving email security has been enhanced with SSL encryption and many other add-ons. Artificial Intelligence has been applied to the system to increase the awareness of the email gateway and security system, increasing the detection of fake messages. By introducing concepts like threat prediction, pattern recognition, and more, AI will change the way email is secured in the future. And its role will not be limited to information security. Its detection capabilities will also extend to all actions related to secure email, such as email forwarding, and email archiving.
SECU E Cloud - Email security solution using AI and ML technology
With many years of experience in the field of network security, VNETWORK Joint Stock Company is proud to provide businesses with an intelligent secure email system with AI and ML applications. Thanks to Artificial Intelligence (AI), SECU E Cloud easily prevents smart attacks from hackers, filters out viruses and new ransomware. Filtering for greater accuracy thanks to Virtual Zone censorship. Every email before being sent to users must go through the Virtual Zone for content moderation. This is considered a big step forward for email security systems, this technology prevents attacks before users can do any action. The system checks the security of email security according to the following criteria:
- Sending and receiving history : Check transaction history with email
- Check for Spoofing Addresses : Determine the Trustworthiness of Emails
- Attachment moderation : Inspect attachments to endpoints. Even if the scammers send nested links, they will still be detected up to the final link.
- Filter Sender IP Address : Check the sender IP to make sure email is not spoofed or spammed. Check the security of the IP and check if the address is on the blacklist.
After evaluating the email received, SECU E Cloud will recommend to the recipient whether to open this email or not. If the security level of the email is over 80%, the new system will send the secure email to the user or just send it in the encrypted form of the system to the user. Emails that are rated as unsafe will be counted and sent to users with a warning.
In addition, emails that are found to contain malicious links or attachments will be converted to images so that users cannot perform any malicious operations. AI and ML technologies get ahead of phishing attackers by eliminating threats before it has a chance to reach recipient mailboxes.
After each email is sent, SECU E Cloud also remembers URLs, attachments, email paths… From there, it creates a data warehouse to warn users when there is something unusual in exchanged emails. daily. Nowadays the importance of secure email is greatly appreciated. Businesses need to equip themselves with a security system, a smart email firewall with the most advanced technology to combat sophisticated attacks. Investing in security is never a waste when a single malicious email can cause millions of dollars in damage to a company. See more features of SECU E Cloud in the video below:
