Frequently asked questions (FAQs)

1. What is Email Security?

The definition of email security is the controls for keeping sensitive information in email communication and accounts secure against unauthorised access, modification, loss, or compromise. The spread of malware, spam, and phishing attacks is often accomplished using deceptive email messages to trick the recipients into opening malicious attachments, leaking sensitive information or clicking on embedded URL links that install ransomware and other malware on the victim’s computer. Email is also a common starting point for attackers to footprint an enterprise network in the early reconnaissance stages that lead to an actual attack.

2. What are the different types of email security?

Email Filters

Spam is traditionally defined as unwanted or junk email. Whether this is purely nuisance email messages akin to the junk mail that is posted through your front door letterbox or, more frequently, a message is seen to be problematic when it may contain upsetting, profane, racist material or more malicious factors enticing users to click on obfuscated hyperlinks to malware, phishing and spoofed web sites. Email and spam filters can block these messages using multiple detection techniques before they are delivered to the end-user.

Anti Malware and Real-Time threat Protection

Email used to deliver malware to a user can be sent as an infected email attachment containing the malware or an embedded URL or hyperlink to the malware. Sometimes the embedded hyperlink is only weaponised at a later date, so real-time analysis of the hyperlink is essential at ”user click-time”. Infected files can be scanned using signature-based detection techniques and more modern analysis techniques such as real-time sandboxing that can detect ”zero-day” malware over and above that which traditional signature-based detection techniques would miss.

Email Encryption

Email transmitted from organisation to organisation can be sent in clear text, making it vulnerable to interception and subsequent data loss. This data transmission can be encrypted to prevent eavesdropping (data-in-transit) but does not secure against messages that reside on the user’s mailbox (data-at-rest) or inadvertently sent to an incorrect recipient, again causing data loss. Encryption can therefore be performed by a variety of tools and methods, ensuring against loss, tampering, spoofing, and ensuring that only the intended recipient can read the message.

Data Loss Prevention

Data loss prevention stops data infiltration and exfiltration capabilities and can be integrated with industry-leading systems.

User Phishing Awareness Integration

Unique in-built phishing education features can help users adopt best practices and identify those who need additional training to improve their security awareness.

Monitoring Auditing and Reporting

As an admin, it is crucial to keep track of the user’s email activity. Mail traffic and usage reports can identify any email activity anomalies and take necessary action to overcome security incidents and compliance challenges.

3. What is Web Security?

Web security refers to the control and measures in place to protect an organisation from threats and cybercriminals using the web as a communication channel. This communication channel is usually, but not limited to, users web browsing and application access. Web security is crucial for protecting users, data, and organisations from risk. Common risks from web threats include ransomware, malware, phishing, malicious sites, and many other inappropriate categories.

Web security controls are similar to those of email security filters in that anti-malware detection, blocked URL categories, user authentication and enumeration, monitoring, and reporting come together to form a comprehensive security gateway or security service that can be used even by remote workers.

4. What are the Benefits of Combining Web and Email Security?

A cyber-attack often leverages both the Web and Email channels to accomplish an attack on an individual or organisation. The implementation of a combined web and email solution can significantly enhance the security posture of an organisation.
