Todo o mundo how to avoid the main threats to which your company may be exposed?
Spoofing and Phishing
Spoofing is a type of technological forgery that seeks to deceive the user, making him believe that the source of information is reliable, settling on his network. Phishing, in turn, occurs when criminals trick the user into revealing personal information, such as passwords, credit card details, social security numbers and bank account numbers. Just like spoofing, they do this by sending fake emails or directing you to untrusted websites.
These two threats have become quite common and, increasingly, cybercriminals have improved their technique to deceive users. How to protect yourself? In addition to investing in antivirus and firewall software so that these threats do not reach your network, the ideal is also to take some precautions, such as:
Do not respond to any email requesting account information or personal data, even if the sender is from a known user or institution.
If you suspect something, do not open the email or link.
Watch out for any changes in the appearance or behavior of trusted sites. Before passing the information requested on the page, be 100% sure that it is true.
Be wary of a tone of urgency and alarm, they are usually dangerous.
Do not open attachments or install anything that comes from unknown emails or that you are unsure of.
Ransomware (Data Hijacking)
Ransomware is a type of attack that makes stored data inaccessible and, usually using encryption, requires ransom payment to restore access to the user. This type of attack happens mainly with companies, and the demand for payment via cryptocurrency, especially bitcoin, has grown.
The most common ways for ransomware to spread are by e-mails with the malicious code attached or that induce the user to follow a link and intrusion due to system vulnerabilities. It is very important to avoid being infected, because once your data is hijacked, it is very difficult to recover it. So stay tuned:
A network engineer is required to have the necessary skills to plan, implement and oversee the computer networks that support in-house voice, data, videos and wireless network services.
Keep the operating system and programs installed with all updates applied;
Have an antivirus, firewall and other security software active;
Be careful when clicking links or opening files;
Make backups to have access to your data, in case your equipment is infected. |
