Due to lack of time or resources, SMEs neglect the risk of hacking. Some common sense rules, however, are enough to partially ward off threats.

Losing data after a computer attack can have serious consequences for a start-up or an SME. The company may never even recover. Website piracy, USB flash drive, password theft, spyware hidden in attachments … Cyber ​​threats are more and more common. What are the simple rules to protect yourself? The point with Stéphane Dahan, president of Securiview, a company specialized in the management of computer security.

5: Protect mobile devices

Mobile stations are potential access points for hackers. According to ANSSI (National Agency for the Security of Information Systems), they must benefit from at least the same security measures as fixed stations. Although this represents an additional constraint, the conditions of use of nomadic terminals even require the reinforcement of certain security functions.
