Today, cyber criminals can break into companies by connecting to their email servers directly. That’s why some business owners choose to implement IP address restrictions to limit the allowed list of connectors to their on-premise mail servers. This prevents hackers from establishing a direct and makes it impossible for them to discover which email server software you run. Leaving no vulnerabilities for hackers to exploit is a good way to keep your system safe.
How does one keep his or her business email intact? One way is to run an ongoing hosted email protection service; these services are often part of managed IT programs. Let’s find out how this type of service deters cyber criminals:
Protects Against Denial of Service (DoS) Attacks
Hackers have the ability to send a large volume of malicious email (email bombs) over a cable modem or limited-bandwidth DSL connection to overwhelm an email server. If a DoS attack takes place, the spammed account will fully expend the given quota of data, which then prevents the victim from accessing genuine messages.
Emails created for the purpose of DoS attacks often contain random/useless information so that they can consume the maximum number of system and network resources. Currently, email DoS attacks can’t be fully prevented but, it is possible to reduce the chance of being victimized. From firewalls to antivirus software, hosted email protection services are also a highly effective solution.
Protects Against Phishing
Phishing is the process of sending emails, with the intention of fraud (posing as a reputable company), to a home user or business user. They are designed to steal login information for social networking sites, banking systems, and other confidential data.
These days, emails are still the critical business service. That’s why the threat of malicious attachments remains huge. You see, more than 60% of the global email traffic is either malicious or spam. Not too long ago, that percentage was a whopping 70%. It is imperative that you use hosted email protection solutions to quarantine these emails before they can be delivered to your email server.
Protects Against Buffer Overflows
What are email buffer overflows? Buffer overflows are recognized as an anomaly where a program, while writing data to a buffer, breaches the buffer’s boundary and starts overwriting adjacent memory. This process often results in erratic program behavior, i.e., causing a breach of system security, system crash, providing incorrect results, and memory access errors.
Unprotected on-premise email servers are susceptible to buffer overflow attacks and that’s why you should opt for a hosted protection service that is infinitely scalable; one that’s able to meet high load demands.
Protects Against Inbound and Outbound Email Flooding
A great array of email servers save their bandwidth and processing capabilities by filtering and processing large volumes of inbound email before allowing legitimate emails to reach on-premise email servers. However, hackers can exploit email server vulnerabilities in an array of ways and turn them into backdoors for future attacks.
Hacking activities facilitated via inbound and outbound email flooding is not an easy task for inexperienced users. If you do not have the experience and knowledge to figure if your email system is under attack or has been compromised, it is time to leave it to the professionals.
