Strategy Guide to Defeat the Three Most Common EPoS Enemies


In this guide, you'll learn how to quickly find how to use a variety of low-cost techniques that will help defend your business against the most common threats to the EPoS system.


At the time of writing, malware accounted for 24 percent of all point-of-sale knowledge violations. Coincidentally, your approach to the EPoS system against malware is similar to that of your PC / laptop:

  • Make sure you have the latest security updates for your operating system (for example, Windows 8 / Windows 7 / Linux / XP).
  • Install the anti-virus package on your system
  • Before you buy, think about following the anti-virus suite
  • Make sure you have at least one firewall, package, or hardware.
  • Software firewall: creates a defense between your PC and the network. So, if another PC on the network is infected, the software firewall can help stop the spread on your PC.
  • Hardware firewall: Routers work effectively as a hardware firewall, providing a barrier between your PC and the network. Routers provide protection for all the computers behind the hardware firewall, making it easier to scale.
  • Download the associated anti-spyware program, such as SpyBot Search & amp; Destroy, this can immunize your PC against spyware (software that secretly collects user data).
  • Some operating systems such as Microsoft Windows 8.1 include Defender software, an anti-spyware software – make sure it is configured and active.

Once you have installed your chosen anti-virus and anti-spyware software, you are halfway to fully protecting your EPoS system

Prevention of hackers

The majority of "hacks" on EPoS systems are easy to manipulate and trust the mental object of the user instead of the hacker's talent and information.

Here are some ways to get rid of vulnerabilities exploited by hackers:

  • Change the default passwords and accounts with administrator access.
  • Set a strong password with 9 or more characters, using a combination of characters, symbols, and numbers on all user accounts.
  • Enable a lockout in case of recurring connection failure

Hackers can also access your systems through remote desktop applications that exploit the vulnerabilities in the code to acquire devices through your EPoS system, your PC, and your network.

To minimize the risk of hackers gaining access through remote desktop applications, make sure your applications are corrected and the most recent update has been updated. .

Physical attack

Piracy and physical attacks are related to the most used techniques to steal information, but physical attacks require a lot of talent and skills, because a data thief must steal a PINpad or quickly connect a skimmer or key logger at the ring road.

Once the thief is successfully assigned, the attack is more difficult to detect because it requires basic information about computer security.

To reduce the risk and injury of a physical attack, do the following:

  • Track your payment terminals and their serial numbers
  • So you can just spot an exchange
  • Use EPOS secure booths
  • Inspect your device frequently
  • Check the seals and protective labels for signs of change of status
  • Note the stripes or marks
  • Train employees to recognize altered devices

Another action plan used by information thieves is for example social engineering techniques: they can create engineers as PDS and "repair" your terminal. While repairing your terminal, the hacker can take this opportunity to drastically alter elements of your EPoS system and thus cause your employees to question any repairer.


It may seem that we have provided you with a long list of tasks to minimize attacks on your network through a compromised EPoS system. But once applied, ongoing maintenance will be relatively minimal. To summarize the essential components:

  • Install firewall, anti-virus and anti-spyware software
  • Frequently transfer patches and updates for the software system and applications
  • Change all default settings
  • Do not use obvious passwords
  • Check for forgery

By following these steps, you will significantly reduce the risk of information theft and ensure the security of your customers' personal data. In the end, the company should have someone (employee or external contractor) to make sure of the company's protective position.
