Cyber-attack risks for companies with employee origins

As part of the initial security relationships we build with new clients, ESET surveys management and responsible employees about what they view as their biggest security challenges. Responses at many large businesses identified the bad security behavior of their employees as one of the biggest security challenges. It is paradoxical that although companies realize that raising security awareness among personnel would increase their organization’s security, by in large they do not invest enough resources into this.

For the purpose of increasing physical security and safety within a company, in many cases employees must attend mandatory training on workplace and process safety, as well as health and fire protection as part of the onboarding process. However, these days a company can not only be put out of operation by a fire, but also via a successful cyber-attack or an angry employee deliberately compromising security. Another very common case is lack of security-mindedness by employees, who might carelessly click on strange attachments or access insecure websites in an effort to solve either personal or work-related queries. Therefore, it is in the interest of employers to raise awareness among all employees about responsible behavior on the network, to support ongoing training and/or e-learning as well as to monitor both access rights and abrupt changes in usage behavior.

Businesses should focus on education along with directives
Companies should implement certain rules of proper internet and network usage. These rules should include what not to click or download, who to consult regarding suspicious mails, and what to do if an employee suspects that something bad has already happened. All this information can be incorporated into a company’s internal directives, which would allow the company to discipline an employee who violates the security directives repeatedly.

However, the directives should go hand in hand with internal education. “Giving a new employee 250 directives to read is not the right way to go. Invariably very few employees ever really read them. It is, therefore, good to educate employees proactively and then assess what they have learned,” says Michal Jankech, the Principal Product Manager at ESET, outlining a more effective way to increase security awareness among personnel.

“Among our customers are companies that invest a lot into IT security training. As a result, every employee knows how to act in specific situations, such as when they see a colleague accessing insecure websites, or when they find a USB key lying in the corridor or sensitive documents left at the printer, and the like. This significantly contributes to the overall security of the company,” explains Jankech.

It may be difficult to recognize a suspicious email
When educating employees on IT security and creating directives, it is important to realize that employees may behave in an unsafe way either intentionally or unintentionally. Bad security behavior can be unintentional when, for instance, an employee is unable to assess whether an email is suspicious or is unaware of what a suspicious link looks like. Attackers often use sophisticated techniques and know-how to make malicious emails look trustworthy – for instance, they may include a link to a fake website of the bank or the company where the employee works. In this case, it is necessary to assess links, validation, and certificates. Of course, that is something an ordinary employee without training would not do.

The unintentional bad security behavior of employees can be further divided into malicious and harmless behavior. For example, if an employee decides to use the Internet for personal purposes and legally buys a movie and downloads it in the corporate network, this can be considered poor security behavior, but is likely unintentional and harmless.

Companies can be held legally responsible for illegally shared content
The situation is completely different when an employee downloads pirated movies or music on the corporate network. In this case, the company may be pursued by the copyright owner for damages and can also receive a hefty fine. This is because in much of the world legal responsibility lies with the person/entity that signed the contract with the internet service provider. In many cases the company would be legally responsible, not the employee who downloaded pirated content at work.

Disgruntled employees can pose a threat to the company
Deliberate malicious behavior occurs when an employee purposely wishes to harm the company. For instance, an employee leaving the company on bad terms could decide to copy the customer database and take it out of the company. Alternatively, a resentful employee could intentionally infect the company’s network or damage its data.

In addition to internal training and the addition of directives, better security behavior of employees can be enforced using technology, such as the use of Data Leak Prevention software designed to protect the company from employee sabotage attempts or data leakage that could cost the company a fine for infringing the General Data Protection Regulation (GDPR).

Comprehensive coverage and visibility
ESET’s security software allows the option to block the transfer of data out of the company on portable media. For instance, the company can determine which employees are allowed to copy data from corporate devices onto USB keys or it can allow data transfer only for specific USB keys that have their content encrypted by ESET Endpoint Encryption. Using ESET Endpoint Security, the company can block access to specific types of websites; for example, websites where employees could upload business data or low-reputation websites that could potentially be a source of malware infection. Another useful tool is ESET Enterprise Inspector, which also enables the search for deliberate malicious behavior of employees.

Data from all these security solutions is made available to IT administrators in a clear, organized form in ESET Security Management Center (ESMC). Thus, IT security within the company not only gain a good overview of what is going on in the corporate network, but they are also be able to solve security incidents in a single click within ESMC.
