What exactly does "Cloud Email Security"
Phishing is the biggest cause of data breaches, accounting for more than a third of instances, according to the 2021 Data Breach Investigations Report (DBIR) that was published by Verizon. In addition to that, it is by far the most typical distribution technique for ransomware.
These days, the majority of businesses have switched to email platforms that are hosted in the cloud and enable a dispersed or remote workforce. Both of these aspects contribute to the rising need of an email security solution that can accommodate an organisation that is geographically dispersed.
Common dangers posed by email
Email may be used in a wide range of malicious activities by cybercriminals. The following are some of the most common dangers posed by email:
Phishing is one of the most popular kind of cyberattack and one of the most serious risks to email. Phishing assaults are also one of the most common sorts of online scams. Phishing emails may be meant to deceive users into providing personal information or money to an attacker, drive them to malicious websites for the purpose of credential theft, or transmit malware.
Malware: There are a few distinct methods that malware may spread via email. When the attachment is opened, it might include malicious macros or other material that runs malicious scripts. This could happen if the email contained the attachment. Emails may also include trojan malware disguised as legal software or may drive users to malicious websites that serve malware. Alternatively, emails may contain attachments that contain malware.
Ransomware is becoming one of the most common types of malware and is one of the most costly and disruptive threats to business cybersecurity. Even though harmful software may be distributed via a wide range of attack vectors, a significant number of ransomware organisations rely on phishing emails as their primary distribution method.
Email was created to facilitate communication, which makes it an excellent medium for the theft of data due to its widespread use. An adversary may deploy a phishing assault to deceive workers into submitting important information, or they may hack an email account in order to access the data that it holds and exploit its links to other online accounts. Both of these methods are vulnerable to attack.
Phishing emails often include links to malicious websites, which are meant to trick recipients into visiting the phishers' sites. These websites may offer malware or seem to be genuine websites in order to steal sensitive information from users, such as credit card information, login passwords, and more.
The Principal Characteristics of Cloud Email Security Cloud email security solutions are intended to provide all-encompassing protection against cyberthreats that are sent over email. The following are important aspects that should be included in any cloud-based email security solution:
Anti-Phishing Methods Phishing attacks are becoming more complex all the time, which makes it more difficult to identify and prevent them. A security solution for cloud email should be able to prevent even the most complex assaults, such as impersonation and corporate email compromise (BEC).
Protection against Malware: Malware that is spread by email may include built-in evasion strategies and defences that make identification and analysis more difficult. Sandboxed analysis should be performed by an email security solution in order to detect malware that has been concealed and quickly provide cleansed data.
Protection Against Account Takeover Assaults The expansion of remote work has led to an increase in the frequency of account takeover attacks. Behavioral analytics should be included into an email security system so that warning indicators of abnormal or malicious activity may be recognised and remedial action can be taken to safeguard sensitive data and ensure regulatory compliance.
Email is a typical vector for data leakage, and businesses have a broad variety of sensitive data entrusted to them. Data loss protection ensures that none of this data is compromised. Email security solutions should enable users to create their own rules in order to secure sensitive data and assist with attempts to comply with regulations.
Comparing On-Premises Email Security with Cloud-Based
It is a must for many businesses to have an email security solution, but it may be challenging to decide whether to choose a system that is cloud-based or on-premises. However, the majority of situations call for a solution that is hosted on the cloud.
On-premises solutions that are appliance based are limited in both the places in which they may be deployed and their capacity to grow to meet demand. On the other hand, cloud-based email security solutions are able to make use of the cloud's adaptability and scalability, which enables them to better match the changing requirements of businesses.
How to Protect Your Email Account
Because email may be exploited in a variety of ways, having many layers of protection is vital for protecting email. The following are some of the best techniques for keeping email secure:
Use Robust Passwords Cybercriminals often use credential stuffing and password guessing attacks in order to get access to employee email accounts. To prevent this, use robust passwords. This risk may be reduced to some extent by adopting and strictly adhering to a stringent password security strategy.
Enable Multi-Factor Authentication (MFA) Accessing an email account with multi-factor authentication (MFA) needs more than simply knowing the password for the account. The effect of a lost or stolen employee password is reduced as a result of this measure.
Put in Place a Security Solution for Email: Email security solutions can identify and prevent a wide variety of email risks, such as phishing scams, malware infections, and the loss of sensitive data. In order to effectively manage the continually changing nature of the threats posed by email, it is vital to implement an email security solution.
Employees Should Be Trained: A significant number of email-based attacks are intended to deceive workers into doing activities that are advantageous to the attacker via the use of social engineering. A crucial component of any email security plan is providing staff training on common email risks and the appropriate responses to such attacks.
After compromising an email account, an attacker may set up mail forwarding or modify settings to enable them to send and receive emails from the compromised account without being discovered. This may be done by monitoring configurations. Audits of email setups carried out on a regular basis may assist in the identification of compromised accounts.
