During the coronavirus epidemic around the world, many employees of enterprises worked remotely from home, and the ecosystem of remote work also witnessed the exponential growth of network attacks. According to the survey of the research organization, since the outbreak of the epidemic, 71% of security professionals said they had noticed an increase in security vulnerabilities and threats.

However, how does this mode change in the traditional business operation and work environment increase the risk of security events? Cybercriminals are taking advantage of the new defense systems of enterprises, which are striving to enable employees to work remotely as soon as possible.

This leads to weak security system, which is easy to be attacked and destroyed by network attackers. They are committed to finding vulnerabilities in the overall security system of enterprises of all sizes. In addition, the current situation and uncertainty after the outbreak of the epidemic show that the mode of remote work will still exist.

Since employees work remotely from home, enterprises need to make every effort to ensure the security of confidential information. The following measures can help enterprises deal with network attacks in remote working environment.

(1) Adopt the equipment provided and configured by the enterprise

Employees’ work devices (including laptops, smartphones and tablets) need to always be equipped with additional security protection layer and configured by the enterprise’s IT department. IT professionals also ensure that each device is updated and well protected against the latest security threats that may lead to data theft.

On the other hand, due to the lack of basic security and defense measures, employees using their own equipment are more vulnerable to various network security threats. In addition, if a personal device is connected to a public Wi Fi network, a security vulnerability may also occur.

Therefore, it is very important for enterprises to ensure that employees working remotely must use the equipment provided by the enterprise.

(2) Control access

One of the major mistakes many people notice is to provide everyone in the enterprise with access to systems, applications, or resources. Access and user management can help enterprises define specific permissions and access to resources according to specific parameters.

For example, an enterprise can provide marketing department managers with access to monthly marketing reports, but need to restrict access to other employees in the same network.

Since the overall security of the network depends on the employees of the enterprise, measures must be taken to ensure that employees report any security problems as soon as possible in any case.

(3) Conduct network security training for employees

In today’s era when cyber criminals are looking for new ways to access sensitive enterprise information, network security training is very important to improve employees’ security awareness.

Although most employees are too confident in their knowledge and agility, many of them are not even aware of the new security threats. Enterprises must formulate clear policies on the use of office equipment and network types, and must regularly carry out network security awareness training to ensure that their employees are familiar with the types of network fraud and how to identify and report these frauds.

Enterprises must also conduct a monthly or quarterly network security test to evaluate the security knowledge of their employees. After analyzing the performance, the enterprise should carry out safety work in the areas that need attention.

(4) Avoid sharing sensitive information via email

Another common error that can lead to security vulnerabilities is the sharing of sensitive information via e-mail, including login credentials. Because e-mail is not encrypted but transmitted in text form, hackers may find loopholes in the network and gain access to confidential information.

Enterprises need to gradually formulate policies to restrict the use of chat messages, e-mail and even instant messaging platforms, so as to avoid sharing confidential details that may affect the security of enterprise data.

(5) View data log

For enterprises, a comprehensive review of data storage and storage hardware and methods to enhance security is essential.

In the era of working remotely from home, it is very necessary to accurately manage data logs and access lists, records, and correct dates and times. Through timely reporting to minimize losses, this can enhance the overall defense against unauthorized access.

Consistent monitoring of these data access logs may be very beneficial for enterprises to minimize security risks.

(6) Avoid public Wi Fi networks

Many people like to use free public Wi Fi networks to access e-mail or log in to their company’s official account, but these public networks are not as secure as people think.

Security experts suggest not to use public Wi Fi connection to carry out online banking, share confidential business details, and even log in to the enterprise portal.

If an enterprise’s network connection is not secure, cyber criminals may try to access their information in different ways, which may be the reason why enterprises should avoid using public networks to connect to the global Internet.

(7) Analyze third party supplier risks

After the outbreak, many enterprises rely more on third-party software suppliers than ever before.

This is because the total development cost of developing and maintaining any software internally may exceed the total budget allocated for this particular software. For example, an enterprise may purchase and install tracking software on employees’ systems to track overall activities during working hours. If the software is not from a trusted vendor, it may further increase the risk of malware attacks.

Experts suggest that enterprises need to carefully select third-party software suppliers, because many suspicious software programs may install malware on employees’ systems, further undermining security.


Telecommuting ecosystems are more vulnerable to cyber attacks because cyber attackers have more targets.

By considering the above security measures, network attacks against remote working environment can be effectively prevented. In addition, educating employees to prevent human errors may greatly reduce the security vulnerabilities of enterprises providing employees with remote work equipment.
