How can malware typically enter a system?

Malware typically enters a system primarily through the method of being downloaded via infected emails or applications. This is a common vector for malware distribution, where unsuspecting users may open email attachments or click on links in phishing emails that appear legitimate but actually contain malicious code. Once the user interacts with these infected files or applications, the malware can execute and compromise the system.

This method exploits human behavior, as users often trust emails from known contacts or official-looking sources. Additionally, malware can be embedded within software applications that users download from untrusted or compromised sources, allowing it to bypass security measures if the user does not have adequate protection or awareness.

Other options, while related to security and connections, do not serve as typical entry points for malware. For instance, software updates and patches are intended to enhance security and address vulnerabilities, not introduce malware, provided they come from legitimate sources. Secure connections are meant to protect data in transit, reducing the likelihood of interception. Network segmentation is a strategy used to improve security by dividing networks into smaller parts to limit the spread of malware, rather than a means for malware to enter a system.
