Network security is an ever-changing field that is constantly evolving to protect your data from cybercriminals, hackers, and other malicious entities.
This is why it's essential to stay up-to-date with all of the newest developments in network security so you can thwart any attempted attack by criminals or foreign governments.
The future of antivirus will consist of many different elements, including new computer languages, better sensors for malicious software, robots capable of recognizing signs of infection before they have a chance to do any damage, and more. However, as technology advances, consumers must remain informed to secure their devices and data. Let's look at how network security will continue to develop in the coming years.
What is antivirus?
Let's start with the basics of what antivirus is. An antivirus program protects your computer from viruses, spyware, and other forms of malicious software (malware). The first computer virus was created by two Pakistani brothers in 1986. Still, before that point, there was no form of the security program to protect your computer because nobody had ever thought to create a virus that would spread from one computer to another.
Antivirus software typically works in two different ways: prevention and detection.
- Prevention software works by identifying malware before it gets on your device and preventing it from infecting the system at all. This can be done in several ways, including checking the file for malicious programming and behavior, blocking a file from entering your system, or scanning all of the files on your computer to catch a virus before it attacks.
- Detecting software is slightly different because it works to identify malicious programs already running on your device. This is usually done by checking for specific processes being executed by malware, monitoring files on your system to identify any changes made by malicious software and more.
How does antivirus work?
An antivirus program will scan every file created on your computer or transfer it. Typically, a program will scan all of these files in search of viruses before they have a chance to infect the system. However, this method can sometimes cause issues such as slowing down your computer or causing it to freeze up.
The most common method that antivirus programs use is heuristics detection. Heuristics detection identifies suspicious coding and behavior that may indicate a dangerous file based on experience and research. This system is more effective than other methods but can still cause problems if developers create malicious software specifically designed to avoid detection by heuristic methods.
Some antivirus programs have remotely-controlled scanning functions available, so you can scan files from an outside source without downloading them onto your device first.
Since 2000, antivirus software has been used to scan emails and links to identify spam. Since spam is typically made up of text with links, antivirus programs can scan the source code for these messages to see whether or not it's dangerous.
How does malware infect your computer?
Malware is a pretty broad term that can be applied to any type of malicious software. It's essential to understand how malware infects your devices and what kinds of software you should watch out for.
- Viruses usually spread through files by infecting them with destructive code to replicate themselves to spread across multiple systems. If an antivirus program does not detect a virus, it can travel to other computers through removable USB drives or memory cards.
- Another way that malware spreads is through peer-to-peer (P2P) file-sharing. The malware will infect a computer's hard drive or memory card and then pass itself to a person who has the infected item and take that person's computer with it. When this happens, the person with the infected device will have no idea that their computer is infected.
Attachments can also spread malware. If you open an email attachment and do not scan it for viruses first, it will infect your device with malicious code passed in the attachment.
How will virus protection work in the future?
The future of antivirus protection is becoming increasingly complicated. New computer languages and coding methods make it easier to create viruses to avoid detection by antivirus scanning.
There are several ways that antivirus programs can adapt to this changing technology, including heuristics, behavior-based protection, sandboxing, and more. Such antivirus solutions save you from data theft threats, trojans, ransomware, and other malicious threats. They scan your computer for viruses and spyware before they enter and try to stop them from doing any damage. They also prevent viruses from spreading to other systems through removable media and peer-to-peer files.
- Heuristics is a method used by many antivirus programs to detect viruses that may be difficult for other detection methods. This method identifies suspicious code on your device to protect it from infection without slowing down your device or damaging the infected file.
- Behavior-based protection is used by some antivirus programs to adjust the way it scans files or processes them to catch any future malware. This method adjusts the heuristics of detection based on how the file behaves, so a process could begin to scan malicious code if it's running slowly or making changes that don't follow a regular pattern.
- Sandboxing is a method used in Windows operating systems that allows for an isolated testing environment where viruses can be tested and prevented from spreading. This method limits the risk of infection by removing all of your system tools, files, and settings to prevent infection with malicious code.
In addition to these methods, antivirus programs may also use machine learning techniques, artificial intelligence, and more to create a process that can constantly analyze new code to keep you safe in the future.
Antivirus technology is one of the most effective protection methods against computer viruses because it can quickly identify malicious software and prevent it from spreading. However, this protection is not foolproof and can be defeated by malicious software that can avoid detection by heuristics scanning or monitoring a file's behavior before it infects your computer.
While antivirus programs effectively prevent malware from infecting your device, they cannot detect every type of malware used in the future. In addition, there are many ways for viruses to spread outside of your device that antivirus scanning does not address.
