07 Jul Secure remote access and communication over VPN
The concept of Virtual Private Network, better known as VPN, emerged as a financial alternative to secure communication through public communication links, such as the Internet, and soon became a technology widely used to approach businesses focused on security, guaranteeing integrity, confidentiality and authenticity of the information.
Currently, several VPN technologies are employed on a daily basis to provide secure communications in the relationship between partner companies within their own business units and for users in transit who increasingly need to be connected to their offices as if they were physically there.
Why are VPNs secure?
Data traveling through public networks is more susceptible to interceptions, as these connections often do not follow appropriate security standards, or simply because security is not the purpose of those connections. For this reason, trafficking critical and confidential company information in these environments requires the use of security mechanisms that hinder the actions of malicious individuals.
When using a VPN, a private tunnel is created within the public network (internet) between the sides involved in the communication (sender and receiver). Before data exits the sender, they are encrypted and encapsulated, going to the receiver. At the destination, the process is exactly the opposite, until the receiver has the original data and performs the processing of the sent action.
This process is only possible because before the connection is established, both sides already have their previous configurations that allow the validity of the access, encrypting and decrypting the network packets that travel the data between the parties.
The encryption allows to provide security for data trafficked, while the tunneling, another technique used in VPNs, allows among other fundamental things the reachability between private networks, or not routable by the Internet. In this sense, not only for the security factor, the VPNs end up being much used to provide remote secure access to companies and people.
Secure remote access: anywhere, anytime
The work of those who use technology as a support tool in their daily life is not limited to a fixed station in company’s office. With the evolution of technology and the companies’ need to make their services available 24 hours a day through the Internet, there is a demand for resources that enable employees to carry out their activities, regardless of where they are.
From this perspective, a company collaborator will have security to access sensitive information through a smartphone on their way to a lunch or even through their laptop at home. One can still work quietly while waiting for a flight at the airport on a business trip if they need to forward an information, check reports, or communicate with colleagues and customers.
Work, especially in medium and large companies, is increasingly decentralized and oriented towards new technologies and mobility. In order to remain competitive in the market, it is necessary to follow this evolution. By allowing employees to perform their work from anywhere, the company gains a considerable increase in productivity and agility, both individual and collective. On the other hand, if access is not offered securely, this can pose a major threat to the business.
Many factors introduce the need to securely route a company’s private data over the internet. As information security evolves, so do cybercriminals, constantly seeking new ways to intercept private data for a variety of purposes. Information systems may not be completely secure, but the use of VPNs to establish remote access drastically reduces the chances of intercepting these data.
Where to start?
The first step is to understand that VPN, by itself, does not characterize a closed product belonging to a single company, but rather, it is a concept and technology, which through the application of solutions and protocols, offer options for secure remote access.
For users who fit the profiles or needs of access and communication mentioned in this post, who do not use VPN to establish communication with their company, can evaluate, together with the technology sector, the possibility of applying the concepts of secure communication, through the deployment of VPN.
For executives concerned about the possibility of exposing information in transit, it is suggested that the responsible sector evaluate the communication processes from the external world to the company, ensuring maximum safety compliance.
