It's impossible to deny that weak passwords will never safeguard your business from data theft or hacking. It's essential to review the passwords and phrases used by your office staff and enhance them according to the tips provided below.

Email Security Tips

It is tough to guess a strong password without any relevant information. The only way for a hacker to gain unauthorized access to a system is by employing specialized software designed to run through millions of password combinations.

The software takes longer to crack complex passwords. Following the best practices below, breaking a password would take 200 to 500 years.

Essential elements for a secure password:

  1. Use capital and small letters
  2. Use numerals and symbols
  3. Avoid using personal information such as your date of birth, hometown, educational institutions, or brand names.
  4. Refrain from using typical letter and number replacements.
  5. Consider concepts rather than individual words.
  6. If you're uncertain about the importance of strong passwords and how to implement them, your organization requires a comprehensive enterprise password management strategy.


2. Double Security: Adding an Extra Layer to Your Login

Implementing two-factor authentication may seem complex, but it's pretty simple. Moreover, it ensures an additional level of security for your emails. Many email clients offer built-in options to enable this feature, and you can also opt for specialized software or switch to a different cloud email provider if your current system doesn't support two-factor authentication.

The idea is straightforward, yet it is a highly effective method for preventing data loss. Implementing this practice increases the challenge for hackers and individuals seeking unauthorized access to your emails.

If a criminal somehow obtains or deduces your account passwords, two-factor authentication ensures they still require a code to access your messages and cause any harm. Typically, this code is sent to their phone via text message. It is essential not to make the error of sending it to your computer, as you cannot be sure who may be observing.

Implementing two-tier authentication is an effective method for safeguarding a social network or web application against data breaches. Furthermore, it is compatible with virtually all cloud storage services that may be in use.

3. Watch Out for Tricky Emails: How to Avoid Scams

Before assisting you in staying vigilant against phishing attacks, educating individuals unfamiliar with the term about the nature of these deceptive practices is essential. Phishing involves a straightforward tactic employed by hackers to obtain email and account information by deceiving individuals into divulging their details.

Typically, the procedure operates in the following manner:

The hacker sends deceptive emails with a link to a website that appears familiar to the recipient, often resembling their bank's site. When the victim clicks on the link and attempts to log in, thinking it's their actual account, the fake site captures their login details and sends them back to the hacker.

If a company member becomes the target of sophisticated malware attacks and deceptive emails, it can be catastrophic.

This is particularly true when the company employs identical passwords for all its office staff. This emphasizes the significance of creating robust, individual passwords for each employee.

Phishing attacks have become increasingly subtle, making it more challenging to detect them without careful attention to detail, as hackers are growing more sophisticated.

Take this phishing email pretending to be from a bank as an example. How quickly could you determine that it's a fraudulent scheme?

4. Attachments 101: Safely Opening Emails Without Risks

At times, your company may receive emails with attachments. This is typically not an issue if you recognize the sender as your accountant and know they expect information from you. Emails from clients or customers rarely pose a problem in this regard.

Now and then, your company may encounter a phishing email, which typically originates from an unfamiliar sender and includes attachments for you to access.

Safely Opening Emails Without Risks

Certainly, discarding all those messages outright isn't feasible, as some of them could be authentic. Therefore, procuring email security solutions to combat potential threats is advisable. This could involve deploying antivirus and antimalware software for email scanning and incorporating sophisticated spam filters. These measures will help identify any potential risks associated with opening email attachments.

If the program alerts you to an issue, you can remove the message, prevent further communication from the sender, and fortify your system. This action will help you avoid a commercial email compromise and any resulting data breach.

5. Email Etiquette at Work: Keep it Professional

To prevent hackers from targeting your email system, it's essential to reduce the opportunities for them to do so. The most effective approach is introducing sophisticated endpoint security measures and controlling the flow of work-related messages to your computers.

Email Etiquette at Work

It is essential to advise your employees against using company communication systems for personal activities such as chatting with friends or shopping online, as this could make the company more vulnerable to cybercriminals.

Implementing such measures does not make you feel uneasy; instead, it demonstrates your commitment to safeguarding the interests of your business and all those working for you.

It's crucial to understand that you must adhere to the same regulations as a business owner. Avoid the error of using your professional accounts for non-work-related purposes.

Instruct your colleagues to use their smartphones and mobile internet to access their accounts whenever necessary.

To maintain a low profile and protect against hackers, preventing anyone from linking their smartphone to your office's WIFI network is essential.

One effective method to ensure their comprehension of the rationale is organizing comprehensive security awareness training for the entire company. This approach can be an excellent means to enlighten them about the significance of safeguarding data, provide insights into email security best practices, and alert them to potential cyber threats and emerging technology trends.

6. Keeping Emails Clean: Spotting and Removing Viruses

Recall the malware and antivirus software we recommended obtaining earlier. It has capabilities beyond simply scanning attachments before opening them. Many top virus-scanning solutions can also examine all incoming emails for vulnerabilities as they arrive in your inbox. The software will alert you if any issues are detected, allowing you to isolate affected emails before they can inflict harm.

Hosted email service users frequently discover that their provider implements consistent security protocols in the cloud, alerting them to any suspicious content in incoming messages.

You are accountable for reviewing your security settings and activating specific options. Occasionally, you may need to pay for this service as an additional feature, so please inspect your account promptly and ensure that your provider scans all emails with antivirus solutions.

If you lack protection, it's the perfect moment to incorporate it.

7. Emails on the Go: Staying Safe in Public Places

Public WIFI is inherently insecure, leaving it vulnerable to various methods through which hackers can intercept and steal all data transmitted across the network.

All it takes for criminals to infiltrate public WIFI networks and eavesdrop on all data is a laptop and simple software. If you or someone in your organization uses email on such a network, you're handing over your passwords and sensitive information to potential thieves. This could lead to a future targeted attack.

If individuals require access to their messages while not in the office, there are a few available choices that should not compromise the security of your operation.

If you cannot access a secure WIFI network, your employees can use their smartphones and mobile data for connectivity.

It offers a higher level of security compared to any public WIFI service, and taking this step will safeguard your cloud data and interests.

Another option is investing in mobile internet dongles for workers to use with their laptops while moving. Both choices are effective and can enhance the security of your business email.

8. Fight Spam Effectively: Building Strong Filters

In the modern era, a significant advantage of cloud-based email services is their inclusion of effective spam filters.

Google's Gmail service effectively filters out most spam from your inbox. It is essential to activate your spam filter or consider switching to a provider that offers more robust security solutions than your current one. Spam filters play a crucial role in sorting through emails and ensuring you are not inundated with numerous marketing messages and weight loss emails each week, thereby preventing annoyance.

Frequently, you can modify your spam filter settings to prevent emails containing specific words or phrases from reaching your inbox. This can prove beneficial if you know current scams, as it allows you to block a wide range of keywords. Doing so can safeguard your employees from inadvertently opening spam emails containing suspicious links or malware.

9. Think Twice: The Risks of Clicking 'Unsubscribe' in Spam Emails

Suppose an email manages to bypass your spam filter and antivirus software. Upon opening it, you realize it appears to be a phishing scam or something. At the bottom of the page is an unsubscribe link, and you might be contemplating whether it's a good idea to click on it to stop receiving further emails from this unwanted source. However, you should never click on the unsubscribe link, as hackers frequently include them in emails to deceive you.

Should you choose to click on the unsubscribe link or do so accidentally, there is a high likelihood that you will be directed to a phishing website attempting to collect any available information. Clicking the link may also grant hackers access to your system, so it's essential to refrain from doing so. Instead, label the message as spam, allowing your spam filter to detect it in the future, and then delete it.
