ESET: With the new data of the coronavirus pandemic, a large number of employees are forced to work from home, without the usual protection of corporate networks.
This significantly increases the chances of attacking a company's digital assets and requires greater responsibility, both from employees and company management. According to ESET, by taking the following steps, employees of any company can greatly enhance their digital security against a potential attack.
1. Check home router settings and change the defaults. Cybercriminals may attempt to "hack" your router and gain access to your network, so it's essential to check your router's settings. Usually, by typing https://192.168.1.1 in the browser, you can see the control panel, and from there change many settings that are directly related to your security. Make sure you change the default usernames and passwords. You will also need to change your home network name (SSID).

2. Scan the home network for unwanted devices. Use tools σάρωσης για να βρείτε ανεπιθύμητες συσκευές στο οικιακό σας δίκτυο. Κατόπιν, αλλάξτε τον κωδικό πρόσβασης και απενεργοποιήστε τις μη αναγνωρισμένες συσκευές από το δίκτυό σας.
3. Firmware update, replacement of old router models. ESET researchers recently discovered the vulnerability Krøk in billionsmillions τσιπ Wi-Fi που χρησιμοποιούνται σε router, γεγονός που αποδεικνύει πόσο σημαντικό είναι να ενημερώνεται το firmware με την τελευταία έκδοση που παρέχεται από τον κατασκευαστή. Αν έχετε ένα παλιότερου τύπου router, η ESET προτείνει να το αντικαταστήσετε, αναζητώντας ένα μοντέλο με δυνατότητες που μπορούν να προσφέρουν μεγαλύτερη ασφάλεια στο οικιακό σας δίκτυο, όπως για παράδειγμα την ανίχνευση και τον αποκλεισμό malware, ιστότοπων phishing και άλλων απειλών σε επίπεδο δικτύου, για κάθε συσκευή που είναι συνδεδεμένη με το router στο σπίτι σας.
4. Use VPN network to encrypt communication. Employees who need access to the company's intranet while working remotely are safer to use a VPN network. In this way, the small data packets that make up communication can remain encrypted as they travel across the Internet, and are only visible on employees' devices and the corporate network.
5. Use of two-factor authentication (2FA). Workers using remote access technologies such as Remote Desktop Protocol (RDP) are quite exposed to attacks. For this reason, if possible, it is a good idea to use 2-step authentication (2FA) solutions. Even if an attacker cracks the passwords, with 2FA they can't proceed, as it requires entering yet another one-time password, usually obtained through an app authentication or SMS.
