Impressive concepts about security and email
Sometimes, we think that the mail is not an important aspect for the security of an SME. Have you ever stopped to think about how much relevant information each day passes through your business email? Professional email solutions have evolved at the rate that they have increased (and continue to increase) the number of Internet threats, in addition to all the improvements related to business mobility and other functionalities that facilitate collaboration.
Email is one of the preferred means by cybercriminals to transmit malware of any kind, due to the great diffusion capacity that is achieved.
Malware (from malicious + software). As the name suggests, it is a software that infiltrates your computer or computer system to damage it. It is installed without us being aware and often spreads via email between our networks of contacts (exponential effect).

Tips to protect your equipment and professional email
Upgrade : keep updated operating systems on computers and servers, browsers and applications across all your devices. The updates usually include improvements in security.
Use original software : in addition to the legal consequences to which you are exposed as responsible (administrator or manager) and your company is exposed, if you do not have original and updated software, you will be facilitating access through security cracks. When you use patches so that they do not identify your illegal software, you are also blocking all updates and, possibly, giving access to your system to the creator of that “crack”.
Be careful with emails : avoid opening suspicious emails or unknown senders. Pay attention to this type of emails and do not get lost! In general, they tend to be based on false offers of employment, an imminent deactivation of the service, changes in the security policy, technical problems or new security recommendations for the prevention – precisely – of fraud.
Browse safely : avoid visiting websites of dubious content, use whitelisting applications-you’ll still have a strong antispam system- and connect to the internet with virtual private networks whenever possible -require authentication and be more secure-.
Limit the number of accounts and protect them with strong passwords : use complex and difficult-to-decipher passwords, and account lockout policies before a certain number of access attempts. In addition, it uses accounts with administrator permissions only when essential and eliminates or disables unnecessary user accounts.
Install security tools : use malware detection tools such as sandboxing techniques , have antivirus systems updated correctly and install security and vulnerability analysis tools.
Avoid sharing sensitive information -account number or similar-by email and in the case where you have to do so, send the documents through illegible files, such as images or graphics-screen captures or photos taken with your mobile, for example -.
