What is remote access?

Remote access refers to connecting to a company computer or internal network in the office from a remote computer or tablet at home or on a business trip.

By using remote access, there is no need to come to work and you can work in a flexible way that suits you, without being tied to your work place.

Advantages of introducing remote access

No longer tied to location

Using remote access eliminates the restrictions on where you work.

You can work not only at home, but also in cafes, satellite offices, coworking spaces, etc.

Also, you don’t have to take a crowded train to go to work every morning.

In addition, by eliminating restrictions on work locations, business can continue using remote access even in the event of natural disasters such as earthquakes, typhoons, and heavy snow.

Reduce your commute time

Leverage remote access to reduce commute time.

On the company side, there is no need to commute, and transportation costs can be expected to be reduced, leading to a reduction in miscellaneous expenses.

Mitigation and reduction of environmental pollution

Off-duty benefits include easing or reducing traffic congestion and, today, curbing the spread of COVID-19.

Security risks hidden in remote access

Unauthorized access to corporate networks

Weak corporate network security can lead to unauthorized access.

When using remote access, in many cases, a company email address is set as an ID. Also, when remote work is done at home, in many cases, the company computer is connected to the home’s local network.

Therefore, if someone gains unauthorized access to your home’s local network, you can control that device and connect to your company’s network.

Tampering with sensitive data

The most typical damage caused by unauthorized access is “data falsification.”

If a company server or web server is invaded and data is tampered with, not only will it hinder normal business operations, but information on corporate sites such as homepages may also be tampered with.

Disclosure and leakage of tampered and erroneous information leads to loss of data integrity and credibility, which in turn leads to loss of credibility as a company.

Eavesdropping and eavesdropping on data

Eavesdropping of data when unauthorized access is permitted is called “eavesdropping.”

As mentioned in the “Unauthorized access to the company network” section, remote access may lead to intrusion into the company network.

By installing monitoring software on the network you are using in the event of an intrusion, you can easily obtain the contents of the data that is sent and received on the network.

Build a communication environment that prevents eavesdropping and eavesdropping, and prevent important information from being leaked.

Malicious use or spoofing by a third party

“Third party spoofing” is also a typical problem that can occur with remote access. Impersonate a user and spy on company information.

Basic causes include the leakage of IDs and passwords due to virus infection and unauthorized access.

Encourage them to change their passwords regularly and introduce a log monitoring tool just in case.Security checkpoints for remote access

Are you using a VPN

RAS (remote access service) and VPN are services used when building a remote environment.

RAS (Remote Access Service) is a service that allows remote control of internal computers and systems from external devices.

On the other hand, VPN is a private network that builds a virtual dedicated line on the Internet and can be used only by specific people.

Since VPN uses its own dedicated line, it is possible to restrict access to unauthorized persons. Therefore, security is stronger than RAS.

Are the access policy and user settings correct?

When using remote access, it is necessary to make sure that the basic security policy, security policy'' andaccessible users” are properly set.

Set a security policy and raise security awareness of each employee.

Also, be sure to configure users properly and grant access privileges carefully.

Thorough log management

Thoroughly perform log management (history management) in order to respond smoothly when trouble occurs during remote access.

Thorough log management will make security measures more robust.

Recommended remote access tools
