Currently, many of the financial operations, consultations, and decision-making processes of large corporations and also of small and medium-sized companies, including banks, insurance companies, and financial consultants, to mention a few examples, are carried out through electronic means.
As this trend became established, leading to a complete change in the paradigm of how the world's economic and financial resources are managed, as well as all sectors of the different industries, the need to guarantee the protection of web pages against computer and cyber attacks began to emerge, giving priority to what is now known as online security .
Website protection
Faced with the increasing development of strategies by cybercriminals, both malware or badware and ransomware , as well as identity theft and phishing , it has become necessary to take increasingly aggressive measures to prevent these types of threats from damaging websites.
Measures
Among the measures taken to ensure the protection of web pages, I will begin by mentioning something called VPN ( Virtual Phone Network ). Many entities, including multinationals that have their headquarters in another country, use VPN to communicate with their remote sites to generate a tunnel through which the data activates the SSL and TLS protocols, alternatively, in addition to AES encryption ( Advanced Encryption Standard ), to prevent this secure and confidential connection from being altered, discovered or decoded.
Another method that is complementary to the VPN is the token: a device that can be physical or digital, which generates a series of numbers that, when accessing different websites, adds another layer to user validation, preventing unauthorized access to information profiles.
In this token system the numbers change based on a table assigned to the token's ID.
There are currently some companies that provide this type of system so that companies in any economic sector can apply this layer of protection to their websites, intranets and internal systems.
CAPTCHAS
CAPTCHAs are part of the strategy used to protect websites. This system was macau business email list designed to establish an additional layer of security since several cybercriminals generated bots ( automated malicious attack microprograms) trying to access secure pages with different user identities until they managed to enter with a password found by elimination.
The above refers to the fact that they tried all the available amounts of combinations until they managed to enter the website or online page of their interest.
CAPTCHAs are a case analogous to what a lock combination would be. They are based on a flat image or photo, and in most cases blurred to avoid image identification by bots , making the user enter the content of that image, usually letters and numbers or objects placed in an image, which requires reasoning on the part of the person who wants to access, thus eliminating the possibility of bots violating the security of a website.
Two-step verification
Another widely used method to protect websites in any economic sector is two-step verification. Nowadays, it is very common for smartphones, tablets and mobile devices in general to access the Internet and many companies or institutions are turning to this type of authentication or two-step verification security layer to make unauthorized access by cybercriminals more difficult.
For this validation to work, the phone or tablet must be registered with a telephone number on the website or computer system, which, upon receiving an unauthorized login or access attempt within the website or system, will send a code to the mobile device by text message or SMS, requesting that you enter said site or system and review the alphanumeric code that appears in the text message.
This system requires the user to have their mobile device at hand and if someone attempts unauthorized access without the phone, they will not be able to enter.
Another advantage of this method and the process it uses to protect is that it allows real-time alerts of unauthorized access attempts, allowing real and legitimate users to take appropriate measures, such as changing their access password.
PIN
Finally, the PIN. That old four-digit PIN system is still valid these days as it is used as a complement to passwords: when trying to enter the system we must have previously registered with a PIN that will be required at the time of access, adding another layer of protection for access to web portals.
These website protection systems for any economic sector can be used in combination or separately.
