![]() Change default passwords, as soon as possible, to a sufficiently strong and unique password. Default usernames and passwords are readily available to malicious actors. ![]() Change default usernames and passwords.It is best to use long, strong passphrases or passwords that consist of at least 16 characters. Select passwords that will be difficult for attackers to guess, and use different passwords for different programs and devices. Note: Because detection relies on signatures-known patterns that can identify code as malware-even the best antivirus will not provide adequate protections against new and advanced threats, such as zero-day exploits and polymorphic viruses. Be sure to enable automatic virus definition updates to ensure maximum protection against the latest threats. It can automatically detect, quarantine, and remove various types of malware. A reputable antivirus software application is an important protective measure against known malicious threats. (see Understanding Patches and Software Updates for more information.) If this option is available, you should enable it. Many operating systems offer automatic updates. Install software patches so that attackers cannot take advantage of known problems or vulnerabilities. To minimize the risks of cyberattacks, follow basic cybersecurity best practices: Attackers take advantage of these errors to infect computers with malware or perform other malicious activity. They can be caused by software programming errors. Vulnerabilities - Vulnerabilities are flaws in software, firmware, or hardware that can be exploited by an attacker to perform unauthorized actions in a system.For example, a program that claims it will speed up your computer may actually be sending confidential information to a remote intruder. Some malware claims to be one thing, while in fact doing something different behind the scenes.This malware can also propagate via email, websites, or network-based software. Once the victim computer has been infected, the malware will attempt to find and infect other computers. Some forms of malware propagate without user intervention and typically start by exploiting a software vulnerability.This action could be opening an email attachment or going to a particular webpage. It might require you to actually do something before it infects your computer.(See Protecting Against Malicious Code for more information.) Malicious code may have the following characteristics: Various classifications of malicious code include viruses, worms, and Trojan horses. Malicious code - Malicious code (also called malware) is unwanted files or programs that can cause harm to a computer or compromise data stored on a computer.The results can range from mere mischief (creating a virus with no intentionally negative impact) to malicious activity (stealing or altering information). Although their intentions are sometimes benign and motivated by curiosity, their actions are typically in violation of the intended use of the systems they are exploiting. Hacker, attacker, or intruder - These terms are applied to the people who seek to exploit weaknesses in software and computer systems for their own gain.Familiarize yourself with the following terms to better understand the risks: The first step in protecting yourself is to recognize the risks. What can you do to improve your cybersecurity? There is no guarantee that even with the best precautions some of these things won't happen to you, but there are steps you can take to minimize the chances. Among these dangers are malware erasing your entire system, an attacker breaking into your system and altering files, an attacker using your computer to attack others, or an attacker stealing your credit card information and making unauthorized purchases. There are many risks, some more serious than others. How much of your daily life relies on technology? How much of your personal information is stored either on your own computer, smartphone, tablet or on someone else's system? What are the risks to having poor cybersecurity? It seems that everything relies on computers and the internet now-communication (e.g., email, smartphones, tablets), entertainment (e.g., interactive video games, social media, apps ), transportation (e.g., navigation systems), shopping (e.g., online shopping, credit cards), medicine (e.g., medical equipment, medical records), and the list goes on. Cybersecurity is the art of protecting networks, devices, and data from unauthorized access or criminal use and the practice of ensuring confidentiality, integrity, and availability of information.
