Data Execution Prevention and How it Works

data execution protection

No matter what you do or where you work, you are likely to encounter Windows software at some point or another. Courtesy of Microsoft, Windows operating software has a massive client base worldwide. With such widespread popularity, it is crucial to understand all the different features and security systems within the software. One such security system that is vitally important but rarely talked about is data execution prevention or DEP. In this article, we’ll take a look at data execution prevention and how it works.

What is data execution prevention and what does it do? How does it work? Why is data execution prevention software important? How can you access data execution prevention settings on your windows device?

Here is a detailed guide to understanding data execution prevention on Windows.

What Is DEP and What Does It do?

Data execution prevention, or DEP, is a security system implemented on all Windows devices. DEP is a memory-oriented security feature that was implemented with Windows 10 software. DEP can be both hardware or software policy setting and is generally decided upon by the user.

The purpose of data execution prevention is to protect your devices against potentially harmful or malicious codes. DEP operates through various programs by scanning its memory for potentially harmful viruses or codes. When used correctly, data execution prevention can be extremely beneficial in protecting your device from external threats and data loss. On occasion, DEP systems can disable and prevent legitimate programs from operating correctly. This is why it’s very important that Windows users understand DEP and how to use it effectively.

How Does It Work?

Data execution prevention systems operate by constantly monitoring and double-checking programs that access memory space. This monitoring of memory space is known as system memory checks. During system memory checks, DEP security systems will filter through and flag any potentially harmful coding or programs. If something is flagged, the program will be immediately shut down and an error notification will be shown to the user. On occasion, DEP systems will incorrectly flag programs that are not harmful, although this usually only happens with older programs developed before the implementation of DEP.

The memory space where programs operate is usually limited on space. Because of these limitations, harmful or excessive coding can overload these memory systems. If the memory space becomes overloaded or corrupted it can lead to software buffering, or worse, it can leave your system and data vulnerable to outside threats.

Why Is Data Execution Prevention Software Important

It is important to note that data execution prevention systems are not a comprehensive way to protect your entire device. Instead, they should be viewed as a helpful defense that can protect one specific part of your Windows systems. While data execution protection doesn’t stop all threats, its function in protecting your Windows memory locations is vital in securing your device.

As aforementioned, if your memory storage becomes overcrowded or corrupted it can lead to many harmful effects. These effects can include slower system operation, increased risk of viruses, data leaks, and much more. In the past hackers could take advantage of overloaded memory systems buffering. They would attack the buffering systems and overload them to gain access to previously secure locations. DEP systems attempt to flag and shut down any of these harmful programs before they have the chance to overload your memory storage.

How Can You Access These Settings on Your Windows Device?

As we mentioned earlier, although DEP serves a crucial function, it can sometimes incorrectly flag legitimate programs. So what do you do if this happens? Here is a guide on how to enable or disable DEP services for specific programs on the latest Windows software:

  1. Click Start and select the Settings tab.
  2. Scroll to the bottom of the page and locate the About button. Click it.
  3. Locate the Device Specifications tab.
  4. In Device Specifications, choose the option labeled Advanced System Settings.
  5. Under this option, find and select the tab labeled Settings.
  6. This should open the Windows DEP settings. From here you can toggle DEP services on or off according to your needs.

Summary

Data Execution Prevention is a security system implemented primarily on Windows products. DEP operates by performing system memory checks constantly in all memory storage locations. If the DEP system notices a program or code that is potentially harmful, it flags it, shuts down the program, and notifies the user with an error message.

So, the goal of data execution prevention is to keep harmful programs and coding from overcrowding or overloading these limited memory storage systems. Likewise, if these harmful programs are allowed to run unchecked it can lead to software buffering and potential external threats. In some cases, DEP can incorrectly flag legitimate programs. However, in these instances, users can follow the aforementioned guide to enable or disable the DEP systems for programs as needed. With the prevalence of Windows software, it is vital to understand what data execution prevention is and how it works.
